Returning to his bedroom again, sun Cheng felt cold all over, as if he had just come out of the ice cave.

    There were three hundred yuan bills in his pocket, which was forced by the fourth. He probably knew that he really had no money now.

    Not much care makes sun Cheng warm, but he still can''t understand the ice cold of his heart.

    Sun Cheng is now quite sure that he has been cheated. He may still be stabbed in the back by a brother he has always thought he was.

    The experience of different worlds not only made him more knowledgeable, but also made his psychology mature.

    Otherwise, if he had discovered such a thing a week ago, sun Cheng could not help thinking that he might have foolishly blocked the door and questioned Liu Kun.

    He closed the door and poured himself a glass of water. Sun Cheng returned to the computer and sat down quietly.

    He needs to be quiet now and sort out his thoughts by the way.

    Although he doesn''t know the details yet, the direction of everything is clear now.

    Someone set him up. Liu Kun estimated that he should be just a helper. Sun Cheng has known him for several years anyway. He doesn''t believe that this guy''s acting skills are so superb. He has kept it from him since he first met him.

    Such a speculation, the result is very interesting.

    Sun Cheng has some self-knowledge. A few years ago, he really stood out from thousands of candidates and was admitted to [Nandu University of technology], one of the top universities of science and technology in China.

    However, with his qualifications and talents, he is not so outstanding in the [Nandu University of technology] where small monsters are clustered and talents are rampant.

    At least NTU has set up millions of scholarships every year to encourage students to make progress, but since he entered the University, he has had a lucky chance to eat once in his sophomore year, and has never had a chance with scholarships since then.

    It can be said that before his entrepreneurship project, sun Cheng could only be regarded as one of the thousands of senior dogs facing graduation in this school.

    So, who''s after him?

    What''s keeping an eye on him?

    This is really a puzzling problem!

    Let''s say it''s entrepreneurial projects. Since the introduction of the college entrepreneurship incubation program by Nanjing University of technology, there are not 100 but also 80 various startups sponsored by the school every year. There are more than 130 of them, including [voice control voice], [shared bicycle], [vehicle system] and other projects with promising prospects based on their names.

    In contrast, although their mobile phone system simulator is less difficult, its temptation has also been thrown away by several orders of magnitude.

    The more he thought, the more he couldn''t grasp the clue. After burning brain cells for a while, sun Cheng had to stop this useless work and turn on the computer screen.

    Before going out, in order to download the IOS system, he turned on the computer and maintained the task all the time.

    The result was quite satisfactory. Although the download speed of the campus network was a bit slow, he still downloaded the latest version of IOS system for so long.

    In the afternoon, sun Cheng had checked some strategies on the Internet, so before he went out, he was added to the download task with the IOS system, as well as virtual machines and several detection software.

    So after installing and loading the software, he learned while watching because his foundation was too poor. Thanks to the ability inherited from "confusion", he quickly got started and began to play with it without much effort.

    "Well, there''s nothing wrong here. The loophole hasn''t been found yet..."

    "When running XX program, there is still a certain chance to cause A9 processor overheating..."

    "XX vulnerability is still there. If it is controlled, you can make emergency calls remotely and continuously..."

    Constantly comparing the IOS system vulnerabilities in his memory, sun Cheng identified them one by one, and soon confirmed with a happy face that all the IOS system vulnerabilities he accidentally cracked when he used to "confuse" the body in a different world are true, and more than 80% of them have not been repaired by apple in the latest version of IOS system, It is likely that it has not been discovered.

    This means that his expected fund-raising plan is feasible.

    He quickly inquired about Apple''s loopholes on the Internet and offered a reward, but Sun Cheng was soon disappointed.

    Apple is undoubtedly stingy. Although the published vulnerability reward is for five categories of vulnerabilities, it will be rewarded up to $200000 if it finds vulnerabilities in the firewall that prevents unauthorized programs from starting. Other reward categories include: discovering the leak of confidential information from secureenclave, with a maximum reward of $100000; The maximum reward for accessing the vulnerability of Apple''s server icloud account is $50000; For the vulnerability of accessing user data outside the security sandbox, the maximum reward is $25000.

    Of course, this is just a statement. It''s high to get half in the end.

    Looking at his harvest, only three of the vulnerabilities detected by sun Cheng can get a high price. The other vulnerabilities are at Apple, which can get a reward of $50-300 at most. It''s pathetic.

    In contrast, he especially visited the vulnerability acquisition platform zerodium in the afternoon. The reward for major vulnerabilities offered by others is 2.5 times higher than that of apple.

    After thinking in his mind for a while, sun Cheng soon had a dispute. He was ready to sell some high-risk vulnerabilities he found to zerodium in batches, while those small vulnerabilities that zerodium didn''t care about were thrown to apple to earn some reputation and hard money.

    When he thought of it, he quickly put part of the vulnerability code he found into two folders. He left complete verification steps for several less serious vulnerabilities, while only the high-risk ones were marked with names. Not only did he not leave the most critical verification steps, but he did not even mark the location of the vulnerability, and then delivered it to the official mailbox of zerodium.

    After doing this, he immediately sent an email to Apple officials with his apple account.

    The rest is to wait for the two families to contact him.

    It took more than an hour to finish these. Before sun Cheng could breathe a sigh of relief, he suddenly heard a knock outside the bedroom door. Immediately a strange Zhongqi Male Stereo got up, "is sun Cheng there?"

    Sun Cheng used to be quite popular, but after he started his own business and began to borrow money everywhere, he began to have fewer and fewer friends. Up to now, he still dares to take the initiative to come to him. In addition to urging him to repay the debt, it is estimated that he will be the same as those in the original bedroom.

    The voice was a little strange. He recalled it carefully for a while and couldn''t remember who it was. It was expected that it must not be an acquaintance.

    As if he was borrowing from the surrounding dormitories, sun Cheng answered, closed the browser and went to open the door.

    At the door stood two young men, one tall and one thin, who looked no older than him.

    Sun Cheng looked at his eyes and looked at them carefully before asking, "are you?"

    "It''s inconvenient to talk outside. Come in and talk!"

    The shorter young man looked very kind, with a smile on his face, but Sun Cheng frowned as soon as he opened his mouth, not to mention that his eyes looked at himself as if they were looking at prey. Just because he was used to the tone of others and the attitude of his master, he was unhappy.

    Before sun Cheng answered, the taller and stronger of the two took the lead in squeezing in without saying a word.

    He was even more dissatisfied, and his tone was wrong. "Don''t rush into the house, you two. Let''s look at the strangers. It''s better to ask first. Who are you? What can I do for you?"

    "Ha ha!"

    The short young man smiled and stopped when he entered the room. The tall man behind him then closed the door. At this time, he heard him say, "just now I was thinking of sun Cheng. My name is Xiao Hong. My friends around me called me ''Hong Shao''. Sun Cheng may not know me, but I should know ''student loan''."

    With that, he gave a look to the tall man next to him. The guy immediately poured out several loan receipts and copies of his ID card from the file bag in his hand.

    Student loan is the campus loan that sun Cheng owes a lot of debt.

    So when the man who claimed to be hongshao mentioned it in front of him, his eyes narrowed, "who should I be? It turned out to be hongshao. It''s rude. I don''t know how to think of my kennel today. Did you come to chat with me?"

    When it comes to debt, he''s not really worried.

    Although sun Cheng was in a hurry to borrow money, he still had some brains. He carefully checked each receipt to ensure that he would sign the overlord treaty. The principal that would be repaid most soon was two months later, and at that time, it was obvious that he would not be short of that money.

    As for the interest, he just paid it back not long ago, otherwise he couldn''t have it in his pocket even before dinner.

    "Ha ha..." Xiao Hong looked at him up and down with interest for a while. He said with a smile: "that will disappoint sun Cheng. In fact, we are here to collect debts!"

    "Of course, it''s natural to pay off debts, but we have to follow the contract!"

    Sun Cheng looked at him blandly, and there was no mood fluctuation on his face: "I have to repay the principal of the student loan with you for two months, and the interest was paid according to the contract last week."

    "Well, that''s right!"

    Xiao Hong smiled and applauded, but there was a little more ridicule in his eyes. "Now the legal system of the Republic of China is booming, and the signed contract should be observed! However, we came in accordance with the contract!"

    He took a copy of the contract from Gao Zhuang''s companion and handed it over. Sun Cheng took it and saw that it was the contract he signed when he started a business loan with the "student loan" in the name of a business project.

    He frowned slightly. After he took it, he didn''t look through it and stared at Xiao Hong: "what do you mean? I still need ten months to repay the principal of the venture loan. As for the interest, I called you last week!"

    "I heard that your business is over!"

    Xiao Hong has made no secret of the irony in his eyes, and even his voice became sharp. "It seems that sun Cheng hasn''t read the contract carefully. According to Article 2.1.1 of the annex to the contract, when the lender can''t guarantee the continued operation of the project, we have the right to ask the lender to repay the principal in advance for our legitimate rights and interests!"

    "So we decided to cancel the loan agreement with sun Cheng in advance. Now, please return the principal of 50000 yuan!"

    With that, without Xiao Hong''s gesture, the tall and strong man next to him sneered, squeezed his fist, pinched his knuckles and bullied him with a crackling sound. It means that if sun Cheng doesn''t pay back, he will invite him to eat an old fist.

    As soon as sun Cheng''s eyes narrowed, he remembered that there was such a clause in the contract signed at the beginning.

    However, his heart was more angry, but there was no panic on Sun Cheng''s face.

    He folded his arms on his chest, sneered and said sarcastically, "Yo, is the news very well informed? I announced in the morning that I would come to the door this evening. It''s really a good means. You installed the surveillance Trojan horse in my computer?"

    Deliberately mentioned the Trojan horse, sun Cheng really saw Xiao Hong''s eyes twinkle.

    Unfortunately, this guy is also cunning. He can''t see any unnaturalness on his face. Instead, he looks at him with an inexplicable expression. "What''s sun Cheng talking about? Do you still want to default?"

    "Liu Kun is one of you. Now I even suspect that you did the job hopping of Huo Miao. Yes, you tried your best to trick me. I''m just very curious. As an ordinary college student, what''s worth your designing so much?"

    Since Sun Cheng has determined that it is him, where can he be fooled by a few words? I am not moved at all. I continue to ask aggressively. In terms of momentum, I have completely turned away from the guest.

    His attitude is so tough that he has noticed so much, which really makes Xiao Hong unable to eat.

    However, Xiao Hong, who quickly reacted, became angry and said coldly, "it''s natural to pay off your debts. No matter how much nonsense you talk, you must pay off your debts. Today I threw my words here. Either fulfill the contract to pay off the money immediately, or borrow money from me to pay off it! Otherwise, let your family pay off your debts for you!"

    After that, he took out a brand-new IOU from his body and threw it over. Sun Cheng, who was quick in his eyes and hands, grabbed it and took it over. His face was colder.

    It turned out that it was a loan receipt that the other party had long drawn up. In order to repay the 50000 yuan principal of the "student loan", he borrowed 120000 yuan from another company he had never heard of, with a monthly interest rate of 3000 and paid off in half a year.

    This is more than usury. Now sun Cheng finally understood what kind of trap he fell into.

    Even if this is a campus loan, it is simply a group of man eating monsters dressed in legal clothes. Once they fall into the mouth of the monster, they will be waiting for him in an endless circle of "pressing for debt, unable to pay back, borrowing and owing more". Until finally, even if the whole family goes to battle to sell cars, houses, kidneys and bodies for him, they may not be able to pay off their debts.

    When sun Cheng saw it, he felt more angry. In front of Xiao Hong, he tore it into several pieces and threw it into the dustbin.

    "... I went fishing this morning, and you couldn''t help jumping out at night. I really think I''m stupid. Now that I know I''ve been set, will I still be led away by you?"

    He sneered at Xiao Hong. "I''ve thrown my words here today. I can pay back the money. Either wait ten months according to the contract, or bring a legal adviser to talk to me tomorrow. In the evening, I''ll work out the process and plan of the entrepreneurial project. Tomorrow, I''ll make an appointment with the school leaders. Let''s have a good chat!"

    "Toast without penalty!"

    Xiao Hong snorted coldly, but when he looked at Sun Cheng again, his eyes were less sarcastic and more dignified.

    His words were like a hint. The tall man next to him immediately rushed to sun Cheng and lifted him up.

    "My ugly words are ahead..."

    Although it was very uncomfortable to be carried by someone with his collar, sun Cheng still looked at Xiao Hong calmly and pointed his right hand at his feet, "this is [Nandu University of technology] , it''s the first university in China, not the street corner of you scum. You have the ability to give me a try. I promise to call the police and say everything. Please believe that there is definitely monitoring on the campus to take pictures of you. I''m looking forward to what will happen if your usury in the guise of "School Park loan" is exposed by public opinion... "

    He smiled at Xiao Hong and said, "if you dare to lend money in Nandu, Hong Shao must have something to do with your family. It''s really expected..."

    "Grass!"

    Xiao Hong''s face was gloomy and his murderous spirit was revealed. For a moment, he was really bluffed by sun Cheng, who was like "rolling knife meat".

    After hesitating for a moment, he gave Gao Zhuangda a cold hum and asked him to put sun Cheng down. Then he said ruthlessly, "OK, I didn''t see it before. You sun Cheng is still a person. But don''t be happy too early. I can''t run if I want to run. I''ll let you go today. From tomorrow on, you can stand it! Army, let''s go!"

    With that, they heard a loud bang from the door. After they looked at him deeply, they left without looking back.

    ps

    Writing the plot of campus loan actually comes from the author. I know the author Jun, who is in college, who is deeply involved in campus loan.

    After borrowing thousands of, he was finally fooled, threatened and trapped by others. He returned more than 30000 before and after, which was returned by his family.

    I have no other meaning in writing. Although I have carried out some artistic processing, the general routine is still the same. In short, I hope you don''t touch that thing easily. It''s black to death.
