Affected by the terrain, the division led by Ma Tianyuan was divided into a combat team of fifty mechas, and they jumped into different pits one after another. The terrain sounder flying in front clearly shows the surrounding situation.

"Alyo, how are you doing there?"

He Qiliao carefully observed the screen, analyzed the elemental detector again, and then answered Ma Tianyuan's question: "For the time being, nothing has been found, and the alien has disappeared underground. ”

The massive mechanical paws of their feet stepped on the slime, and the liquid gurgled out along the tooth marks.

The data of each detachment was unified on the command platform in the mecha, and Ma Tianyuan could see the panoramic information, but he still had no bottom in his heart:

"Be careful not to be too far apart between the squads."

He Qi Liao answered, and took the lead and turned the corner in front of the pothole, which immediately became another world.

A medium-sized cavity appeared here, and at the other end of the cavity, three new holes appeared on the cave wall, and the slope behind it became noticeably steeper.

Faced with this situation, He Qiliao began to hesitate a little, the team he led only had fifty mechas, if he divided the troops to enter, it would be very scattered, and it would not be able to form an effective combat ability, and now he had to wait for the team behind him to come.

Soon, the other two squads burrowed into the hole, and the number of mechs had reached one hundred and fifty.

Just as they were about to burrow into the cave, a "pop" sound came from one of the caves in front of them, and a team of mechs came out of it.

When the leader saw the situation in the cave, he was immediately surprised: "Hey, how did I get on your route?" ”

More information has been gathered here by He Qiliao and Ma Tianyuan, and now everyone has discovered a new situation:

These passages do not go directly into the center of the earth, they are interconnected, and the army burrows into a complex labyrinth.

"Release more terrain sounders, the rear control center will immediately calculate the accurate line, and if the process is affected, the detachments can violently break it."

Ma Tianyuan immediately gave a new order, and the teams went into different caves again.

On the ground, Command stared nervously at the central control platform, where a holographic image showed the movement of each detachment.

The dense red dots representing the combat units dispersed into the "transparent" passages, and then, like mercury seeping into the sand, the red dots became noticeably scattered.

As the depth increases, the "transparent" passages become denser, forcing the human ranks to diverge, and the Red Tide now looks more like a light mist.

"What if the forces are too scattered? The combat effectiveness of our mechs is not as good as that of aliens. ”

Yan Chengjian looked at the map worriedly, and the hearts of every general here began to become worried.

Zhang Binhui pursed his lips: "The quarantine convoy can set off, and it will be attached to the outside of the two combat units."

Don't worry, with the support of the alliance, I added some material to each team. Although the underground labyrinth forced us to disperse our forces, they were still scattered within the "separation walls".

Now the degree of integration of combat units is still acceptable. If aliens are coming, we won't be at a disadvantage in numbers.

My only concern now is whether our troops will be able to adapt to this new combat environment. ”

……

With a "click", Bruce Lee's feet collapsed, and the ground seemed to be deep, and the ground with a radius of dozens of square meters suddenly collapsed, revealing a bottomless black hole underneath.

He Qiliao's eyes were quick, and the huge mechanical arm stretched out and scooped Bruce Lee's mecha in his hand, so Bruce Lee hung in the air.

"Yikes!" He Qi Liao instinctively shouted, and then lifted upwards with force, and the metal weighing more than fifty tons was dragged up by him.

The two men stood side by side on the edge of the black hole, looking down with trepidation. Bruce Lee folded a glowing rod and threw it down the black hole, only to see a circle of light sink into the darkness along the straight hole.

It's so deep!

He Qiliao gasped, and then released the detector on his arm. With a "buzzing" sound, a vertical passage with a depth of about two kilometers appeared on the new map.

"Don't go in, the vertical environment is not conducive to the development of our formation, it's a trap."

Ma Tianyuan issued an order at the first time, and his rich combat experience allowed him to see the effect of these vertical deep holes at a glance.

The observer mapped the inside very clearly, and the diameter of the deep cavern shrank dramatically, apparently to limit the deployment of the human mech.

In such an environment, the aliens can calmly perform their escape skills, while the humans cannot maintain a battle formation. Get in? Surely death!

He Qiliao understood what Ma Tianyuan meant, and his face turned obviously blue. With a strong shake, a jade ball appeared in the "palm of his hand", and He Qiliao threw the spiritual weapon into the deep hole.

A slight "poof" sound sounded continuously, and the ball did not fall into the deep hole, but was suspended in mid-air.

Following the direction of gravity, a series of phantoms flashed along the deep hole, as if they had fallen from a sphere.

Two seconds later, eight spirals of light were released from each of the shadows, reaching the vertical walls of the cave before slowly turning.

"I told you to yin me, but I want to see who is yin and who!"

Gritting his teeth, He Qiliao never looked at this deep cave again, he shouted: "Follow me", and then led the team into another cave.

According to the route given by the command, He Qiliao's team will encounter a solid wall after 300 meters, where their cave will reverse course and return to the line of the G9 team.

"Bang it out for me".

A hundred meters away, two mechs raised their mechanical arms, and the other mechs held a huge shield in front of them.

According to the data transmitted back by the detector, there will be another pothole on the back of this thirty-meter-thick wall, which will be the next forward route for He Qiliao and them.

Just as they were about to fire, the image behind the wall suddenly shook violently in the mech's analog display, and a sharp spike slashed across the camera, and then all images disappeared.

"Spot the alien and fire with all your might!"

He Qiliao's nerves, which had been tense, were immediately "broken", and with a snap of his index finger, a huge cannonball blasted out along the crater.
