100 kilometers away from the ga18-313-e position, there is a wind-eroded Gobi Desert and a small rift valley. At this moment, several snake-like people are digging holes in a crazy manner. Their strong body muscle tissue and sharp claws are good at digging holes. The direction they face is the ga18-313-e position. This has happened at multiple locations in the entire ga18 area battlefield.

Local indigenous intelligent creatures also know how to use tactics, which is obviously a strategy of fighting against the west. They also know the huge technological gap between the two civilizations. A breakthrough that may not be achieved with crazy human-sea tactics on the front, and must be prepared for both hands.

At this time, the human troops were indeed attracted by the frontal offensive of the snake-like army, and they had never thought that they would dig into the tunnel underground to find a breakthrough.

In order to gain enough time for the opening of underground passages, snake-like people completely use their lives to pile up, using the "human sea tactics" to restrain humans on the front battlefield without stopping.

The defensive Marines were also frightened. To be honest, they were also scared by these desperate crawlers. They were the real outlaws. Once they broke through the defense line, it would be a nightmare, so the Marines on the defensive position were not ruthless at all. If you don’t die, you will die.

...

At the same time, on the other side, there is a lush mountain ridge here. In fact, this is a large volcano, but it is an extinct volcano, and the inside of the volcano is a natural shelter.

A strong air disturbance suddenly appeared above the volcano. More than 400 vanguard soldiers led by Li Qing were coming from the orbit to the surface and arrived here. The beacon guided them here.

More than 400 people arrived at the top of the volcano. A vanguard soldier walked up and said, "The regiment commander, according to the information sent back by the agents, the shelter of the snake-like people is in the area 3,000 meters below the volcano. This is the map of the ground network that was passed back."

Li Qingzheng's window immediately showed a three-dimensional image. This is an underground network based on volcanic lava rush. Under the transformation of snake-like people, it is connected in all directions, like an underground maze, and it is simply a natural underground and shelter.

"How many asylums are there?" Li Qingzheng said.

"No less than one hundred thousand!"

"Be good, so many, we have to cut one by one with our necks stretched out and we have to cut one by one for three days and two nights. How can we fight this battle?"

Li Qingzheng thought about it and immediately notified the whole team: "Our mission is to safely transfer snake-like eggs. Most of the volcanoes have narrow channels at the bottom. It is good news. The opponent has a large number of people but cannot expand the formation. It can be said that one man is a man who cannot open a thousand men. He uses two people as a unit to guard a necessary passage, thus establishing a temporary safe transfer route, and the rest of the people transfer the mission targets."

While speaking, Li Qingzheng calculated a path to the underground snake-like egg bank through an internal computer, and the forks along the way were also marked. There were 94 narrow barriers to be guarded, which means 188 vanguards were required to guard.

Li Qing immediately dispatched the mission and divided the troops he brought into two groups. One wave of troops was 188 people responsible for guarding the key points, and the remaining vanguards were responsible for transferring snake-like eggs.

"Everyone has it, do you understand their respective tasks?"

"no problem!"

"Action!" Li Qing was saying frankly. Suddenly, more than 400 vanguards jumped into the crater. After entering the bottom, they soon found a pit hole deep into the ground. It was a pitch-black pit with a rough appearance and covered with volcanic ash. However, the inner wall of the pit had a clear rock luster, which was quartz crystal, also called mica, a substance unique to the inside of the volcano.

Li Qing, who led the team, was the first to jump into the pit. It was obviously a slope with a low angle. After a period of time, he stepped on the straight ground steadily, and his eyes were dark inside. However, as a high-tech armed vehicle, the night vision device and the biological thermal imager system are indispensable.

After a while, the vanguards entered one by one along the sloped pits. The silence and gloomy place here is definitely the place where claustrophobia is most reluctant to come.

Li Qing was leading the team to move forward in a small step. Their location was on the top of the narrow slope of the crater, and the slope just now was a good proof.

The team went down the main road, and the deeper the light became, the dimmer the light was until it passed through a corner, and the team entered the complete darkness.

Although this is a volcanic shelter after the transformation of local indigenous civilizations, there is no light source inside. In fact, indigenous civilizations have mastered power technology and light bulbs.

However, darkness is not a hindrance to them, because they can have the ability to position echo like dolphins and bats, and can avoid all obstacles even if there is darkness in front of them.

Although the vanguards are humans and do not have such capabilities, the high technology inside the nanoarms can assist them. At this moment, the vanguards entering the underground network channel display this night vision image on their window panel, and also turn on the biological thermal imaging instrument.

After all, there can be thousands of reptiles hidden inside this extinct volcano.

After walking for a distance, the vanguard would take out a thumb-sized device from his body and embed it on the barrier of the passage. These are communication transponders. They go deep into the bottom of the volcano. The metal minerals contained in the soil inside will affect communication, causing communication interference and poor circulation to occur with the inoculation.

These communication transponders allow encrypted electromagnetic signals to "turn around" and ensure smooth communication between the entire team.

As the team continued to deepen, the main road gradually appeared forks. Every time a fork was encountered along the way, the team would divide two vanguards to guard the other branch line until the task was completed and evacuated.

After reaching a vertical height of two thousand meters, Li Qing was leading the team along the established route. When he turned a corner, a sharp claw suddenly came without warning, and Li Qing was seeing a red biological thermal imaging profile through the window.

Immediately afterwards, a reptile creature exposed half of its body, like a cobra walking. If it was bright here, you could see its small eyes filled with bloodthirst and anger. The anger that could only be brought about by the undying enemy was burning with rage, as if it was burning rage, and opened its bloody mouth towards Li Qingzheng.
