A group of people walked through the weeds and arrived near the first-level laboratory, and were stopped by a five-meter-high barbed wire fence. This was not an ordinary barbed wire fence. Su Chen didn't know the specific material, but he knew that the barbed wire fence contained high voltage.

Electric current can electrocute an elephant instantly, let alone a human being.

This is a national first-level laboratory, which contains many important national confidential documents. All defensive measures are not humane at all. If you are not careful, even a veteran special forces soldier will be at risk of death.

"Lieutenant, is the power outage?" It has been many days since the end of the world, and Su Chen is not sure whether the power grid in front of him still flows with high voltage current.

"Logically speaking, there shouldn't be. Even if there is a power outage in the whole city, the first-level laboratory has backup power, and the first-level laboratory also has an independent large-scale generator. As long as there are enough raw materials, it can last for a month," the lieutenant replied.

.

"Okay, tell me how to get in." Su Chen spread his hands, not wanting to think about these issues.

"Go to the main gate, there is a guard post there." The lieutenant had a detailed map of the Level 1 laboratory. Except for a few classified areas that were not marked, he knew the Level 1 laboratory very well.

Su Chen thought the lieutenant was planning to blow the door to pieces. When he arrived at his destination and saw the door that he couldn't describe, he gave up his ridiculous idea. Not to mention using a gun, the ten-meter-high thickened door in front of him

The steel door, even if a tank comes in, won't be destroyed unless it hits it three to five times.

There is a fifteen-meter-high sentry post outside the gate. The post is not large. It is equipped with four heavy machine guns. It is connected to a computer in the first-level laboratory and can automatically recognize human faces. Once confirmed, it will fire immediately.

When Su Chen and the lieutenant climbed to the top of the outpost and saw the red indicator light, Su Chen was able to confirm that the first-level laboratory was still in operation.

If there is a power problem in the first-level laboratory, the external defense will give priority to cutting off the power. After all, the power consumption of the power grid can be compared with that of several experimental buildings.

The space on the top floor of the post is very small and can accommodate at most two people at a time. After the lieutenant confirmed that there would be no problem with the rope, he threw it towards the post within the power grid. The post within the power grid was manned and was larger and higher than the ones outside.

After the lieutenant made sure everything was safe, he signaled to Su Chen, then grabbed the rope and crawled over slowly.

The rope is at least ten meters above the ground. Falling is no joke. If you accidentally fall onto the power grid, you will be really unlucky.

The distance between the two outposts is only fifteen meters, which is just a few steps for Su Chen, but climbing a rope at high altitude is not an easy task.

Su Chen followed the lieutenant, and the other two special forces were on the tower to confirm the stability of the rope. In case of special circumstances, they could also help.

Su Chen had never climbed a rope before, which put great demands on his shoulders and even his whole body. However, what Su Chen did not lack most was strength. He was just a little nervous.

Soon, Su Chen and the lieutenant arrived at another outpost. The lieutenant reinforced the rope, and other special forces followed closely behind.

After everyone entered the first-level laboratory, hundreds of zombies swept by dust and smoke arrived outside the first-level laboratory.
