A large number of mechanical spiders entered Passage Seven, and soon discovered that there were some branches in the depths of Passage Seven, which did not know where to lead.

Ye Han really wanted to check all these passages, but the mechanical spider was a little insufficient.

So he led the team into the No. 7 passage, rescued the drones that served as repeaters in the temporary passage, and threw himself into the great cause of exploring the No. 7 passage.

Coincidentally, as soon as the troops entered the No. 7 channel, Ouyang Ping blew up the No. 5 channel, and the communication between the two sides was blocked by the complex terrain.

There are seven forks in the depths of passage seven, marked as minus one to minus seven, and dozens of mechanical spiders scatter into the seven passages, with an average of a dozen per passage.

Then Ye Han found that these negative channels are really intricate, there are more forks in each fork, some of these forks are not related to each other, and some are connected to each other, forming a dense three-dimensional tunnel system like a spider web.

The strange thing is that there is no shadow of aliens in the maze at all, Ye Han couldn't help muttering in his heart, could it be that all the aliens have gone to the fifth passage, so that the troops in the depths of the passage are empty?

Luo Qi suddenly said: "Commander, look, the minus four has found the enemy!" ”

Ye Han immediately received the video turned by Luo Qi and found that the mechanical spider had entered a hemispherical cave hall.

The cave hall is about 30 meters high, with a diameter of not less than 40 meters, and as far as the eye can see, both the wall and the ground are very rough, not like artificial excavation, but like a naturally formed cave.

Europa does not have the conditions for the formation of a cave, and this cave hall is just an ordinary underground cavern.

Through the lens of the mechanical spider, it can be seen that there are thirty or forty aliens in the cave, and they have crossed the cave hall and burrowed into a dark passage on the other side of the cave hall.

The alien's actions immediately caught Ye Han's attention.

The aliens in Passage 7 and Passage 5 are all dead, and it is said that the enemy should concentrate his forces against the Airborne Division at this time, but this group of aliens has come to the opposite direction and gone in the opposite direction.

Although this place is a little far away from the shaft, and it may not be known the situation in those two passages, shouldn't it be time to mobilize troops to focus on containment?

"Let the spiders follow!" Ye Han gave an order, since this passage was marked as minus eight on the map.

The mechanical spider immediately went into action, and the screen shook violently due to the spider's movements, until it was better to chase into the negative eight passage.

At the same time, Luo Qi mobilized the mechanical spiders near the cave hall to concentrate in the direction of Negative Eight, focusing on exploring this area.

After entering the passage, Ye Han found that the cave wall of Negative 8 was obviously much smoother than the cave hall, which was obviously the result of artificial excavation by aliens.

The spider chased all the way down the passage, about seventy or eighty meters, and suddenly a blurry shadow flashed in the shaking lens.

Ye Han suddenly shouted: "Stop, go back!" ”

The mechanical spider immediately stopped, taking a few steps backwards from its original path.

"Retreat!" Ye Han said again.

The spider complied, and the fleeting shadow re-entered the camera.

"Here, lean in!" Ye Han pointed to the position of the shadow and said.

At this time, Luo Qi also saw that something was wrong, and said hesitantly: "This seems to be a person!" "The place where the shadow was was a little collapsed, and a humanoid thing was half-buried between the sand and stones, and it was impossible to see it clearly unless you looked closely.

"Definitely not ours!" Luo Qi said with great certainty.

Passage No. 5 and Passage No. 7 were both in charge of the third regiment, and the soldiers did not rush to the negative head branch hole, how could it appear so far away?

"Probably someone from the multinational force." Ye Han said, "They should have a force in this direction." ”

At this time, the mechanical spider had already climbed onto the man's arm, and the slender mechanical legs swept away the dust, and a tricolor immediately appeared in the camera.

Now all doubts have been answered, there must be a friendly army in the depths of this passage, and those aliens are rushing over to encircle and suppress the multinational forces.

Ye Han let out a long breath and snorted coldly: "The spider will follow immediately, and the troops will set off immediately!" ”

"Yes!" Luo Qi agreed, and immediately asked in a low voice, "Division Commander, are you able to evacuate if you rescue them?" ”

Ye Han scolded with a smile: "Just you are clever!" ”

Luo Qi smiled, why didn't he understand what Ye Han meant?

It is true that the airborne division can be evacuated on the grounds of excessive casualties, but the underground situation is invisible from space, and the multinational fleet can blame the airborne division for not contributing to the work, so the northern capital will be very passive.

But after rescuing a friendly army, it is not the same to evacuate on the grounds that there are too many casualties, and if you rescue a friendly army, you will suffer so many casualties, you can't know that it will be difficult to continue the rescue, and throw all the airborne divisions into it, right?

Even if the multinational fleet is good, the northern capital has to be willing.

The troops were about to set off, and at such a juncture, Ye Han suddenly received a communication from the rear: "No. 1, No. 1, please answer if you receive it!" ”

"Ouyang Ping? Is that you? Ye Han immediately recognized the voice.

"It's me, it's me!" Ouyang Ping was as happy as a child, "Teacher, I've found you!" ”

"Don't be too happy, I can't go out yet."

This sentence was like a basin of ice water poured on Ouyang Ping's head: "Why? ”

"We've spotted a friendly army."

That's good news!

Ouyang Ping hurriedly asked, "Which country?"

"The tricolor, the devil knows which country it is." Ye Han complained very sharply.

He always thought that those featureless tricolors were too strange, and always suspected that the rulers of these countries were too lazy, otherwise why use the tricolor flags that are so easily confused as the national flag?

In fact, he only needs to look through the information stored in the biochip to know which country the flag belongs to, but he just doesn't bother to move.

"So what do we do?" Ouyang Ping asked.

"How many people did you bring?"

"Two companies."

"Call for support immediately, call the guard battalion and the training battalion over, who is in charge of the shaft now?"

"Third Commander."

"Let him watch the shaft and this passage, and don't let the enemy copy our back road."

"Yes!"

"Also, Ouyang, you wait for the follow-up troops, and I'll pass you the route of the first move in a while......"

Ouyang Ping hurriedly refused: "Division commander, the Dragon Regiment has no reserves in its hands, except for the troops I brought, the other troops have tasks, and they can't be withdrawn for a while." ”

"Then you explain the situation to Lao Long first, and then lead the team to follow!"

"Yes!"
