"There have been battles here..."

    Billy searched carefully in the smelly office for a while. His palm was full of cartridge cases, "NATO standard 5.56 mm rifle bullet..."

    Major Dutch took a cartridge case from Billy''s palm, looked down and recognized its specification.

    "It''s weird here!" Billy continued.

    Major Dutch looked up at him. "Anything else?"

    "It''s strange!"

    Billy went to an office and pointed to several rows of bullet holes on the wall: "the bullet holes left by these shots are very divergent, which looks more like those left by aimless shots..."

    "Huh?"

    "It''s the same here... Here... And here. There have been battles here, but these people seem to have lost their reason and shoot everywhere!"

    He immediately went to the three corpses nailed to the wall. He didn''t feel sick. He took out a military knife from his body and pointed to the wound, "the wounds are in the heart, and it seems that they were directly penetrated by some cold weapon, and died on the spot..."

    Major Dutch vaguely grasped the meaning of his words, but there were still some places he didn''t understand. He simply asked, "what do you mean?"

    "Besides dinosaurs, there are some more dangerous things on the island. They may not eat us directly like dinosaurs, but I''m afraid they want our lives like dinosaurs..."

    Billy replied firmly, waving the saber in his hand several times, with an eager expression.

    The dead bodies in the office were quickly counted. A total of 23 were all adult male bodies. However, because their heads were cut off and their skins were peeled, even sun Cheng with a good memory could not tell how many of them were security personnel on the island and staff of international genetic technology companies.

    In addition, it was not clear whether there was any danger in the research center. Major Dutch did not stay in the office full of dead bodies. They quickly locked the doors and windows, and then they withdrew in turn.

    "The search on the second floor is over. Make sure you haven''t found anyone!"

    "The third floor is sure, no one..."

    "The windows on the fourth floor are not damaged. All the rooms have been checked and there is nothing!"

    "No one on the fifth floor..."

    After more than ten minutes of careful inspection from the first floor to the fifth floor, major Dutch returned to the first floor again without finding any survivors or suspicious traces.

    "There are so many people on the island?"

    Major Dutch played with a broken M16, his face as gloomy as iron.

    This M16 was found somewhere on the first floor of the research center. Naturally, it is not difficult to see from his eyes that it was directly cut off by someone using a sharp weapon during forced resistance.

    "It''s impossible. There are no less than 20 security personnel left on the island..."

    Sun Cheng shook his head and rejected his words. His face became more and more anxious.

    Since he entered the research center, the revenge in his arms has never stopped shaking. In just half an hour, I''m afraid I have to remind him more than 20 times. It has been moving almost once a minute. It''s obvious that it has found something very difficult. However, there are people around Sun Cheng from time to time who can''t get away and ask it.

    However, major Dutch did not think much about his abnormal behavior. They had just seen a hell on earth. Even these hundred war veterans have failed to calm down, not to mention an ordinary person in their eyes.

    "Dutch, let''s go eat first!"

    Black soldier Dillon came out of an office with a gun. He didn''t hide his intention of action just now. Therefore, everyone saw him looking around the office. It seemed that he was interested in the cloning, genetics and gene modification technology of the international genetic technology company.

    Major Dutch thought and nodded slowly. "Hawkins and Harlan, you two go to the kitchen and bring some food and two bottles of wine by the way! Bin, try to contact the base."

    When they visited the floors of the research center just now, they had already determined where the kitchen was. Moreover, as sun Cheng said, there were not only a large number of frozen fresh food stored in the freezer, but also a lot of ready-made cooked food.

    "All right, major!"

    Harlan and Hawkins answered, and soon went to the kitchen with their weapons, ready to bring some food.

    As for the messenger bin, after receiving his order, he also took out the satellite communication equipment and tried to connect with the outside world.

    "Dillon, we have to talk about it!"

    Major Dutch glanced at Sun Cheng not far away. The meaning could not be clearer.

    He was worried that he couldn''t be separated from the soldiers temporarily. He couldn''t help but rejoice at the sight, and his anxiety disappeared, "I''ll go to the bathroom!"

    With that, sun Cheng turned and walked to the bathroom not far away.

    After entering the bathroom, he made sure that no one was following him. Sun Cheng quickly pushed open a cubicle and sat down on the toilet. He took revenge from his neck and couldn''t wait to ask, "what''s the situation? It''s been shaking since just now..."

    "In addition to the previously locked stealth unit, after entering the building, I once again captured another unit using ''optical stealth'', and it is now lurking in the building and is currently moving to the first floor. In addition, I just received the communication from the defense, and it has got what you ordered!"

    Defender took the initiative to contact revenge and got what he wanted, which is really good news for sun Cheng.

    However, a trace of excitement had just risen, but Sun Cheng disappeared after he learned from revenge that there was another invisible person!

    "There''s another invisible man!"

    His heart sank. Just now, after meeting an invisible man who used optical stealth for the first time in the hills, their team only lost one person. In addition, revenge determined that he could kill the target, so sun Cheng didn''t have much fear of these invisible people at that time.

    But just now, according to the analysis of Indian soldier Billy, the tragedy in the research center is likely to be caused by these invisible people.

    At the thought of the images of beheaded and skinned corpses in his mind, sun Cheng felt depressed and uncomfortable, but he had the idea to kill them.

    "Where is the defender now? Can you contact him?"

    "It is now in the underground control center to copy data. In addition, according to the data it just fed back, there are several survivors hiding below, including IDA Wang. Do you need me to summon it?"

    "Basement?"

    Sun Cheng suddenly saw dozens of cruelly treated dead bodies in his office just now. He really thought that other people in the research center had escaped, so although he knew there were two floors underground, he really didn''t think about it.

    Unexpectedly, everyone hid in the basement.

    He was thinking about whether to call the defender to protect himself secretly. Suddenly, the revenge lying on his leg squirmed all over, took the initiative to change back to the shape of a Decepticon, flew up, and suddenly shot a slender alloy blowing needle at a place above the compartment.

    Sun Cheng was stunned. He subconsciously looked up at the top. He was so scared that his legs softened and almost didn''t cry out.

    "Squeak!"

    Above the compartment, accompanied by a strange electromagnetic wave, a ferocious tall humanoid monster appeared on his head out of thin air and immediately fell down.
