After finishing his clothes in the mirror, sun Cheng nodded with satisfaction.

    The casual suit he was wearing was prepared for his business a few months ago. So far, sun Cheng clearly remembers the experience of frugality for more than a month in order to buy himself a decent suit.

    Nandu has been able to feel the heat in mid April, but even so, he must wear a suit to go out today, because after a short wait, Apple''s email reply finally came.

    The corners of his mouth could not help bending an arc, and sun Cheng''s face was also hung with an emotion called "complacency".

    After all, he is still a normal young man. This time, with the loopholes of many IOS systems he has mastered, apple, a giant that can definitely rank among the top 10 enterprises in the world, can''t wait to ask him for contact information. Even when he learned that he was in Nandu, the headquarters of the Chinese branch, he immediately arranged a vice president of the company to meet him.

    How can this not make sun Cheng feel very proud?!

    He cleaned up carefully, took out a brand-new USB drive and put it in his pocket. Then he locked the door and was ready to go out.

    Not far from the dormitory building, sun Cheng saw a familiar face. The man was happy when he saw him and hurried over.

    "Ah Cheng, are you going out?"

    The visitor''s name is Lulan, who is also one of sun Cheng''s classmates and creditors.

    Sun Cheng followed his voice and recognized who it was. He couldn''t help smiling. He nodded and asked, "old road, it''s almost the end of the month. Are you here to ask me for money? I''ve made an appointment with an investor and I''ll meet you later. If you''re not in a hurry, come to my bedroom tomorrow. If you''re in a hurry, I''ll pay you back your 2000 in the evening."

    In order to start a business, he really owed a lot of foreign debt, including several classmates who used to play well.

    However, since the start-up projects also went wrong one after another, some gossip kept blowing in the class, which made the relationship between many people and him cold.

    Therefore, seeing that a return from Apple was about to arrive, sun Cheng thought that the money could not run away. Without waiting for him to speak, he directly determined the debt repayment in advance.

    This forthright attitude obviously stunned Lu Lan. He hesitated and asked, "ah Cheng, aren''t your entrepreneurial projects yellow? If you don''t have money for the time being, just give it to me later to avoid embarrassment!"

    Sun Cheng''s eyes narrowed slightly. In the real world, he just announced the dissolution of the entrepreneurial team the day before yesterday. It spread so quickly. It seems that there are few people behind it.

    After thinking about it, he asked tentatively, "did Lu Lei? Huo Miao? Or did Liu Kun tell you?"

    Lu Lei, Huo Miao, Liu Kun and sun Cheng are the four initiators of his entrepreneurial project. The first two and Lulan are classmates and know each other. Although Liu Kun is sun Cheng''s roommate, he often meets Lulan. Maybe they don''t know each other as well, but they must know each other.

    Lulan really didn''t hide him. Maybe he didn''t feel it. "I met Liu Kun last night. I heard him mention it!"

    Sun Cheng turned his mouth and whispered, sure enough, but he was not ready to mention more about it with him.

    "Liu Kun left the entrepreneurial team more than half a month ago. He doesn''t know the details of us. Well, I''m in a hurry now. If you don''t worry, go directly to the door of my bedroom in the afternoon. Oh, by the way, don''t call me. My phone fell the afternoon before yesterday and is still being repaired!"

    In the end, he was a classmate. He talked about this one. Even if Lu Lan had concerns, it was not good to say more. He nodded at the moment. He didn''t come at the time, but he didn''t refuse. It seems that he believed the rumors.

    After sun Cheng said that, he didn''t delay any longer. After saying goodbye to him, he quickly walked to the school gate, stopped a taxi at the gate, and soon disappeared.

    The meeting with apple and others was arranged by the other party in Jiangning, where sun Cheng is located. It was cheaper for him. It took him less than 20 to get there by taxi. It was a very unique coffee shop.

    "Sir, how many of you..."

    As soon as he got to the place, a waiter came forward. Sun Cheng nodded slightly, "I have an appointment. Where is room 3013?"

    "Please follow me..."

    He followed the waiter all the way to the private room area on the third floor. He soon saw 3013. He quickly thanked the waiter and walked over by himself.

    After taking a deep breath, sun Cheng knocked on the door.

    "Squeak!"

    The door of the private room was soon opened, and a thin middle-aged man wearing gold wire glasses came out.

    When he looked at Sun Cheng, his eyes suddenly brightened. Before sun Cheng could speak, he asked, "is your excellency Mr. Sun Cheng of [Cybertron studio]?"

    [Cybertron studio] is the ID used by sun Cheng when reporting vulnerabilities last time. However, just yesterday, he changed his name at the Bureau of Commerce and changed the original "cross studio" to Cybertron.

    Sun Cheng knows the brand quite well. Only from the other party''s clothes and temperament of no less than five figures, he can judge that the thin middle-aged man who shows his face may occupy a high position in apple.

    But his state of mind adjusted better than he thought. He smiled, nodded and replied, "it''s me..."

    The middle-aged man shook hands with him and said with a smile, "no wonder they all say ''generation is stronger than generation''. Mr. Sun Cheng has such deep computer technology at a young age. At this age, I am still worried about my graduation thesis at MIT!"

    Although he mentioned MIT, a famous American school, sun Cheng didn''t respond much.

    Although he is a famous university in Europe and America, his [Nandu University of technology] is also the leading institution of higher learning in China. It is not necessarily worse than others. Sun Cheng is still proud of this.

    The middle-aged man immediately said, "I haven''t introduced myself yet. I''m Liu Qingmin, vice president of Apple China branch!"

    I didn''t expect to be a big man!

    After introducing himself, Liu Qingmin warmly greeted him into the private room.

    Sun Chengcai walked in and immediately felt several lines of sight falling on himself.

    After a closer look, it turned out that there were two men and a woman sitting in the private room. Except that the woman wearing professional clothes and black framed glasses was still very young, the four men looked over 30.

    After entering the private room, as soon as sun Cheng sat down, Liu Qingmin introduced him: "let me give you a brief introduction. These two are the vulnerability testers of our company, and this is our legal adviser, Miss Chen Wei! Although that may be a little abrupt, I''d like to ask Mr. Sun Cheng first, you [Cybertron studio] Are there any loopholes in our company''s IOS system? "

    "Indeed!"

    Sun Cheng nodded and stopped talking.

    He knows what the IOS system in his hand means for apple, so it''s the other party who should be anxious to sit on the Diaoyutai despite the storm.

    Sure enough, it''s the apple that can''t sit down first.

    Seeing that Liu Qingmin was very mature, he had to say, "thank you again and your studio for your support for our apple company. It''s inconvenient to talk in detail in the email before. We haven''t told you about the loophole reward reported before."

    Sun Cheng''s ears moved, which is really his most concerned problem at present.

    Fortunately, Liu Qingmin didn''t lift his appetite. He nodded with Chen Wei, the legal adviser next to him, took out a document from his briefcase and handed it over.

    Sun Cheng took it and found it was an agreement.

    Although the agreement is only two short pages, a few minutes have passed after reading it word by word.

    After reading the agreement, he put it back on the table. Although sun Cheng could not see many changes on his face, he was still very satisfied with the agreement.

    Apple''s reward to him is not rich, but it''s also authentic. As long as he promises to sign the agreement with a confidentiality period of half a year, they will immediately pay sun Cheng a total of 20000 yuan in cash, about 3000 US dollars, much more than he expected.

    However, although satisfied, sun Cheng felt that he should fight for himself again. He said at the moment: "I have no opinion on other aspects, but the half year confidentiality period is too long. Most of the loopholes we found are just remote. It''s hard to say when they will be discovered by others! You will be held accountable at that time. Our small studio can''t afford your accountability."

    "Mr. Sun, this..."

    Chen Wei, Apple''s legal adviser, was about to argue when Liu Qingmin waved and interrupted.

    Seeing him meditate for a moment, he nodded and made a compromise: "yes, the confidentiality period is shortened to three months!"

    Sun Cheng looked at him in surprise. Obviously, he didn''t expect the other party to make concessions so easily.

    The three-month confidentiality period was almost over. Sun Cheng thought and nodded, "three months, it''s acceptable!"

    Chen Wei then took out another blank document that had not been filled in the controversial part from her briefcase. After making some changes, she handed it over together and said, "please sign in these blank spaces on the document and provide me with a bank account. I will pay the bonus to the account provided by Mr. Sun within five minutes!"

    After sun Cheng did it immediately, Chen Wei quickly took out an apple laptop and transferred 20000 yuan in cash from the financial account to the bank card he provided in front of him.

    Although he only glanced at her transfer in a hurry, sun Cheng felt that such a large apple company should not be able to deceive himself for this money, so when the other party''s prompt was completed, his tight nerve line immediately eased down.

    Liu Qingmin obviously knew the truth of striking while the iron was hot. With this basis for cooperation, he spoke again and went straight to the theme.

    Just listen to him: "I wonder if you can talk to us about other loopholes?"

    "Yes!" Sun Cheng replied simply. Obviously, the other party''s cheerfulness made him very satisfied with apple.

    Took out the newly bought 2G USB drive from his pocket, and sun Cheng directly handed it to him, "there are 31 IOS vulnerabilities in it, including my discovery process and detailed analysis..."

    Hearing that there were so many more, all the people from Apple changed slightly.

    Liu Qingmin thanked him. After receiving the USB drive, he handed it to the two testers he brought. They saw that they inserted the USB drive into the computer, opened it and looked at it for a while, and tested several Apple phones against the same equipment.

    The whole process lasted more than half an hour, and the good news continued.

    "The first vulnerability is determined to be the same as'' dfgh-1562-6584 ''found by the head office!"

    "The second vulnerability is true. There is no problem with process verification!"

    “……”

    The detection reports of the two technicians continued, and the loopholes provided by him were continuously confirmed to exist.

    However, to sun Cheng''s surprise, Liu Qingmin, vice president of apple, who has been paying attention to the progress of testing, looked at Sun Cheng from time to time with brighter eyes and thicker smiles. He took the initiative to chat with him.

    "Mr. Sun Cheng and your [Cybertron studio] really give us Chinese a long face. You don''t know. There have been few bugs found by our Chinese branch in recent years, which have been satirized by the technical team of the headquarters..."

    "I''m older than you. Call you little brother and be closer!"

    "Oh? My little brother used to be a top student of Nangong..."

    "I don''t know how many people there are in your [Cybertron studio]? Are you interested in working in our apple company? With your technology, I guarantee an annual salary of more than 100000. It''s really easy..."

    The other party''s solicitation was so enthusiastic that sun Cheng couldn''t bear it, so he had to flatly refuse: "thank you for the love of president Liu. Our [Cybertron studio] members are some college students of Nanjing University of technology. The reason why we have this studio is to gather everyone with dreams to start a business together, so I can only tell you I''m sorry..."

    Liu Qingmin still had some perseverance and patiently advised: "little brother, you should know that although entrepreneurship has good prospects, the risks can not be underestimated. It is not possible to succeed with technology. After I graduated from college, many classmates and friends joined in the tide of entrepreneurship in Silicon Valley, but there are few Winners..."

    Sun Cheng just smiled and nodded, but he didn''t think so.

    Now he has an adventure. His future achievements are unlimited. How can he go to work for others.

    Liu Qingmin wanted to persuade him again, but when he looked at his firm attitude, he could only sigh a pity, but he still left room for future solicitation: "well, I wish you success in your business. Of course, if you think it through in the future, you can contact me at any time, and the door of our apple will always be open for you..."

    Although sun Cheng disagreed, he still exchanged contact numbers with him.

    Here, two apple testers who have been busy for a long time have finally completed the detection of the last vulnerability.

    When the words "the last loophole is detected and the problem is determined to exist" fell, all eyes in the private room fell on Sun Cheng again.

    Facing the eyes of several people, he smiled gently.

    Sun Cheng knows that in the real world, Yang Fan will set sail!
