The research building was silent late at night. In the middle of the night, all but one room on the third floor had the lights turned off early. Tian Zheng and the others quietly touched over, and while the sentry at the gate was not paying attention, a wolf-toothed soldier quietly touched it and cut the neck of the Japanese sentry with a knife. The sentry's body was quickly pulled into the grass behind and hidden, and the crowd rushed in. When he walked to the second floor, Tian Zheng made a gesture, and everyone stopped. Tian Zheng motioned to take out the bow and crossbow. The two wolf-toothed warriors took out the folding compound crossbow from their backpacks, pulled the bowstring, and loaded the crossbow arrows. Tian Zheng held one in his hand, and another wolf-toothed warrior held one in his hand. Tian Zheng stretched out his fingers and counted from three to one. When the gesture was reached, the two nodded to each other and rolled violently, gently rolling out of the ground. At the same time, the two of them quickly determined the location of the two Japanese sentries at the staircase on the third floor according to what they saw out of the corner of their eyes, and the crossbow arrows in their hands were fired at the same time. Accurately hit the throats of two Japanese sentries. The two Japanese sentries were not yet dead, and they were about to sound the alarm, but the two wolf-toothed soldiers who followed had already thrown the multi-purpose military thorns in their hands, and hit the two dying Japanese sentries in the chest and heart.

The power of the crossbow is strong, but this folding crossbow is not very powerful due to the characteristics of easy carrying. If the central nervous system in the target's forehead is chosen as the attack point, there is a high chance that the bolt will not be able to penetrate the target's skull, so that the enemy will not be able to resist with the first attack. Choosing the throat is the fastest way to kill the enemy, and a single blow can make the enemy unable to make a sound. And because there is no fresh air, the vitality is quickly lost. But he couldn't die in the first place. Then a knife in their heart. The destruction of the heart will stop the heart from supplying blood, thus allowing the target to die as soon as possible.

Bypass the bodies of the two Japanese sentries. The group quietly entered the third floor.

The third floor of this research building is the core of Unit 731 of the entire Japanese army. On this floor. There is the general dispatch room of the Japanese army's biological and chemical weapons research in China, the most complete and up-to-date research results of various branches, the latest production of preparation samples, many virus research reports that have not yet been approved, and of course, the top leaders and core research experts of the entire 731 Research Institute.

In this third layer, there are a total of more than 30 colonel-level officers and four generals, that is, all the core personnel of the entire 731 unit. Nearly one-third of the entire floor of the third floor is designated as the living area of these elite technicians, and the remaining less than two-thirds of the space is a sample warehouse, a reference room, an office, and the like.

The Japanese apparently did not expect anyone to infiltrate the third floor of the building without alarming anyone. Therefore, it is only a sentry at the staircase on the third floor, and its function is more to prevent people who do not have permission to enter the third floor. Arguably. This time, the officers and men of the Wolf Tooth Special Operations Brigade were able to enter the third floor smoothly, which was also directly related to the blind arrogance of the Japanese army.

"The six of you go collect research and virus samples." Tian Zheng pointed at Liu Ming's wolf-toothed warrior and said, "The six of you go to control the school officer's dormitory and escort them out!" You, go to the first floor to patrol! You, follow me to the general's dormitory! ”

Tian Zheng's gesture command was crisp and concise. Suddenly, Tian Zheng seemed to remember something, hesitated, and transferred two of the six wolf-toothed warriors assigned to control the school officer's dormitory. Let them go to the observation area and cell on the second floor, and when they have retreated, they will take all the people inside out of the diabolical compound.

Tian Zheng originally planned to retreat with these detainees. But then it occurred to me that most of them were wounded, and the discipline was too low. If you join in the retreat, it will inevitably increase the risk of a lot. At that time, I am afraid that not only will they not be able to take them out of the army, but even the main target of my troops this time from afar - those backbone personnel of the Japanese army's biochemical virus research will not be able to take them out of the city!

At this moment, Tian Zheng felt a sense of guilt in his heart. But. He quickly got rid of the negativity. As a qualified commander of special forces, Tian Zheng profoundly understands the importance of making decisions on the battlefield. And the order of making according to the importance of the goal is not the slightest psychological hesitation! These poor people, even the most prodigious, were discovered by the Japanese army. After the cooperation of the officers and soldiers of the second group of wolf teeth is broken, the losses should not be too great. But if we can't bring back this group of core personnel of the Japanese army's biochemical virus research. Then this group of frenzied Japanese fascist invaders will cause even greater damage to the land of China!

The operation went well. When more than 30 Japanese military colonel-level officers found out that they had been captured, several of them could not accept this reality and were ready to take up arms to resist, but they were shot on the spot by the wolf-toothed warriors with crossbow arrows from folding crossbows! The remaining twenty-six Japanese military colonel-level officers immediately became honest! Some sources say that the Japanese officers and soldiers during World War II were all masters who would rather die than lack! That's pure nonsense! Although the Japanese army had a militaristic influence, and most of the soldiers were very loyal to the country and the emperor, many of the high-ranking officers were mostly raised by some large families in Japan. In particular, some civilian officers who are engaged in technical research are no worse than those traitors in China in judging the situation and seeing the wind and steering the rudder! The Japanese officers who were shot dead on the spot were probably those pure fanatics! Some horrific behaviors are only taken for granted by these madmen! Therefore, shooting these Japanese officers on the spot, Tian Zheng's summary is not that he regrets the lack of a few talents with research results, but that these scum are innocent!

When he came to investigate in the afternoon, Tian Zheng saw the scene as if he was still in front of him. That situation had already been communicated to the members of the two groups. So when the four wolf-toothed soldiers present looked at these Japanese military academy-level officers, their eyes erupted with fire. If it weren't for Tian Zheng's explanation, I'm afraid that under the situation just now, there would definitely not be just seven Japanese officers and researchers who were killed!

And Tian Zheng took a wolf-toothed warrior and kicked open the door of the dormitory with the words Shiro Ishii written on the door number!

Shiro Ishii was a lieutenant general in the Japanese army. You can enjoy a standard dormitory on your own. The other three major generals share a dormitory. When Tian Zheng kicked open the door of Shiro Ishii's dormitory, another wolf-toothed soldier rushed into the room where the three Japanese major generals were.

Four Japanese generals were escorted to their knees. Shiro Ishii was a rather arrogant Japanese general. Because he not only has military talent, but also is a top student majoring in biology. What is even more worthy of his pride is that he is a high-ranking samurai of the Japanese Jiuju family, the most accomplished person in this generation who has been put into the army! Therefore, Shiro Ishii pays great attention to his appearance on weekdays, and he can't tolerate a trace of messy hair, and he can't tolerate a speck of dust in his shoes! But now he was dragged out of the bed directly, and he didn't have the noble aura he usually had at all, with messy hair and untidy clothes, and he didn't even have time to put on his shoes on his feet, so he was cut behind his back, and his hands were tied tightly with strings and knelt on the ground, completely becoming a prisoner!
