Looking back, we should find an appropriate time to send a signal to the outside world. If the members of the sword team have arrived, they should know what to do.

"All the staff should stand separately according to the type of work. The police should come to our side and the scientific research personnel should stand on the other side. The people of each project should not be mixed up in the battle line. No one can be an exception, or they will be killed on the spot!" Just then a man in the shape of an officer stood up and cried.

As soon as the words came out, the originally chaotic crowd began to stand apart in an orderly way. Han Fei saw that it was not good. All the members of the project team knew each other. Besides, there were three new faces of the dragon team, who didn't even have a biochemical suit. After they had assembled, they didn't even have the slightest cover left.

In this case, whether to stay or not, the three men in the dragon group lost their backbone and looked at Han Fei nervously, for fear that Han Fei would leave them behind.

Han Fei also knows that in this case, he must get out as soon as possible, otherwise he will drag on, and then he will face the suppression of the firepower of the entire armed base.

Looking at the location of the entrance just now, we can see that the defense there is still very tight, but if we fight together, there is still a great possibility to break through from here.

"You three follow me closely. It's a dead end to fall behind at this time." Han Fei said to the three men in the dragon group.

The three people's hearts suddenly sank, one of them trembled and said: "instructor Han, do we really want to break through by force? Is there any way to be a little warmer? "

Han Fei looked at the guy's face and joked: "there are gentle ones. You have the potential to be a little white face. If you can get close to one or two fags, it's not impossible to save your life."

The guy subconsciously turned to those bearded men. Just looking at the beards made him sick. If he really wanted to get involved with these fags, maybe even his constipation for many years would have to be cured. He would rather die at the thought of that picture.

"Instructor Han, let's go. We'll follow you." The other guy said.

In fact, this is also their last chance. Seeing those people stand apart one after another, the scene is divided into several squares, and soon they will be exposed.

As for Lin Zifeng's face, he was even more pale. He had been forced by a knife in his chest before. In addition, it was violent exercise to follow Han Fei out of the underground base. At this time, it would be his life to let him break through.

"I'm afraid I can't get out. Don't leave me. I don't want to die!" The wind in the woods was afraid at this time.

If he had died in the laboratory before, it would have given him the hope of life. Now he is faced with despair. The feeling from life to death is maddening.

Han Fei looks back at Lin Zifeng. He can't see a trace of blood on his pale face. He hesitates for a moment. Then he takes out a syringe and says to Lin Zifeng, "do you want to have an injection? You may die with one shot, but if you don't, you will die. "

Lin Zi was full of fear in his eyes, but he also knew that the reality would not leave him much time. As long as he could live, even if he had a chance of life, he would fight for it. Now he gritted his teeth and said, "I'll fight!"

As soon as the voice fell, the syringe was directly inserted into Lin Zifeng's heart. Looking at the decisive hand, it seemed that even if Lin Zifeng didn't agree, Han Fei's needle would stick to him.

At present, time is pressing, so we can only use this way of opening the skylight to achieve quick results, which is also the decision Han Fei made after weighing for a long time.

This reagent was taken by Han Fei from inside the base. If there is no accident, it should be the super serum injected by those soldiers.

Sure enough, this just injected less than two seconds, Lin Zifeng became a lot of spirit, originally not burly body, at this time also had a trend of expansion.

"Now! Go As soon as Han Fei's voice fell, there was a huge explosion at the entrance of the underground base.

Before leaving, Han Fei had already dropped all the button bombs on his body. Now, with remote control, the destructive power of devastation instantly caused the underground entrance to collapse, and the surrounding dozens of meters were affected, and the invisible waves instantly destroyed a large number of people.

The commander on the scene roared, including the soldiers, instinctively rushed towards the entrance. For a moment, all the police forces of the whole base were attracted by the explosion, and the defense force at the gate was also sparse.

Han Fei rushed out at random, and the whole person turned into a shadow. At this time, the three people in the dragon group also took out a desperate posture and distributed all their strength on their legs. At this moment, everyone's speed was as fast as that of a full speed car.

Although this will have a great load on the meridians, and even the risk of disability in serious cases, their lives are at stake now, and they don't care about anything.

At the same time of the explosion, the people in the sword brigade also cheered up. They knew that the explosion would never be accidental.

With the help of high-power telescopes, they clearly saw that three people suddenly rushed out of the original bustling crowd and came straight to the gate. Especially when they saw that the leader was Han Fei, they were all excited.

"Fire!"

Words fall, two rockets directly toward the metal gate, with those people in the guard room also with the disaster, Nuo big metal door was immediately blasted out of a huge hole, which undoubtedly provided great convenience for Han Fei and others to leave.

When those people in the base reacted, a piece of covered fire fell from the sky. For this operation, those people in the sword brigade were equipped with weapons secretly developed by the National Security Bureau. Although they were not as good as the metal storm, they could fire a million bullets in a minute, but it was light and easy to finish a thousand bullets in three seconds.

The super long range is enough for them to attack the base from the ancient trees, but more than ten people form a dense fire suppression network.

Even though the soldiers were willing to resist, they could not find out where the enemy was, and even if they knew the direction, the distance was beyond the range of their guns.

Under the cover of strong external firepower, Han Fei and others quickly evacuated from the inside of the base. Seeing that Han Fei had left the wall, several members of the sword brigade immediately set up an electromagnetic gun to aim at the entrance.

As soon as the switch was pressed, there was a loud bang. The concrete wall with a thickness of several meters collapsed instantly. Large blocks of stones fell from the air and blocked the entrance. It took a lot of effort to clear out the ruins, which also gave them the necessary time to evacuate.

As for how many casualties this attack caused, it's not something they are considering. It's the only way to get out of the rainforest as soon as possible.

Han Fei and his friends were not far away from the dense forest, and then they joined the sword team. When they saw that the only three people in the dragon group were alive, everyone's heart sank slightly.

"Retreat quickly, and be careful of idle armed men in the rainforest." Han Fei said.

As we all know, it's not the time to remember our teammates. We must march and leave here under the cover of the night. Although it's taboo to drive at night, it's hard for them to fly when it's daybreak!

The night has restored its original tranquility. Even the experimental base has calmed down after a period of noise. Everyone is cleaning up the ruins of the entrance in an orderly way. Now it is necessary to repair the circuit, restore communication and get in touch with the outside world as soon as possible.

Unfortunately, the calm inside the base didn't last long. As a bloody hand came out of the collapsed tunnel, fear spread in the base.

There was a lot of gunfire and fear. After half an hour, the inside of the experimental base was quiet

At this moment, in a secret military command of the United States of America, a bearded general looks grim at the picture of the UAV coming back.

Because of the danger and importance of the experiment, they would contact the experimental base every hour, but something went wrong today.

Since the last contact, now a full half an hour has passed, no matter how they call, there is no response in the base.

The general was worried, and then sent a drone to drive past. When he saw the scene taken by the drone, the general was also angry.

"It's definitely the group of people from Huaxia National Security Bureau who have made a comeback!" Cried the general angrily.

With the more detailed pictures brought by the UAV, the muscles on the general's face became stiff, and the original anger was gradually replaced by fear.

"Biochemical man! It turned out to be a biochemical man! "

When he saw that group of biochemical people organized to clean up the ruins of the entrance, the general immediately understood the seriousness of the matter.

Before, in their eyes, those biochemical people were just immature failures, just like wild animals, they only had the instinct of killing, but now this scene undoubtedly refreshes their understanding that these biochemical people are intelligent and hierarchical.

At present, a group of biochemists work together to clean up the ruins. As long as a few biochemists stand far away, it seems that the leadership is the same. This is a shocking discovery. Once this group of biochemists who have wisdom and know how to disguise themselves escape from the base, the consequences will be unimaginable!

After all, wearing clothes, they are no different from ordinary people. Once they lurk in the crowd, God knows what kind of chaos they will cause.

"Blow it up! I blew it all up! Take the experimental base as the center, carry out carpet bombing for me in a radius of 50 kilometers. I want to blast every piece of land into scorched earth. Even an ant can't get out of here alive! " Cried the general crazily.

The people on the side looked at the general in horror. The carpet bombing in a radius of 50 miles was not a joke. Once it was exposed, even the president would be quite passive!
