The gate opened, and Lin Xi did not rush in at the first time, but raised his gun on guard. No matter how you look at this door, it looks like it was opened by itself, and no one knows how many war beasts are hidden behind the door.

The gate slowly opened, opened to a width of more than two meters, and then stopped. Behind the door was empty, a deep and dim passage, filled with a faint mist, and the visibility was only a dozen meters.

Lin Xi waited for a while, but he didn't see the door move, nor did he see anything rushing out inside. She gestured as a warrior leaned against the door, shining a laser beam into the passage. He shook the laser transmitter and quickly and meticulously swept across the entire cross-section of the channel, and there was no trace of the war beast for at least a few tens of meters.

The soldier used ultrasound to measure again, and made a gesture of safety within 100 meters to Lin Xi.

Lin Xi and Chu Jungui walked in first.

The thickness of the gate is actually two meters, and the part embedded in the passage is as high as 30 meters! People standing in front of such a gate are like small insects.

After Lin Xi and Chu Jun returned to the door, they no longer went deeper, but surveyed on the spot. If the door suddenly closes after entering, everyone will be locked up in the Jedi. It's hard to blow up such a door, even if you want to.

The passage is flat and round, 10 meters wide and 20 meters high, allowing even the largest giant rhinoceros to move freely. The walls of the passage are particularly hard and look like shells, and are dark brown.

On the inside of the gate, a large number of muscle-like tissues appeared. Chu Jungui gently tapped those dark purple tissues, which had the texture of leather, and were indeed muscles.

These two doors are actually like the mouths of some giant creature, and the opening and closing are all muscular force.

Could it be that the whole valley is full of the body of some giant creature, and if so, what are these two doors, the mouth, or something else?

It's not a good thing to think about something so big that you open your mouth and wait for someone to go in. Thinking like this, Lin Xi didn't dare to go in at will.

Chu Jungui stood beside him, thoughtful. He had just opened the door by disturbing the current, but he didn't expect the door to be muscle-controlled.

In other words, the subject quite scratched the big guy, and then the big guy couldn't stand it and opened the door himself.

Then Chu Jungui thought of another possibility, just now he knocked on the door and told the big guy that the food was coming.

The subject didn't want to go deeper.

But everyone can't freeze here, let alone waste more time, who knows when the next round of beast tide will appear. This time it was equivalent to a sneak attack, but it turned out that there was no one in the opponent's lair, so he just picked up a big bargain.

Lin Xi suddenly sneered and said, "So many beast tides have resisted, are we still afraid of a thing that can't move?"

The political component jumped out and tried to say that he disagreed, but was pushed back by the subject.

Aside from the test subjects, the other fighters appeared to be a little hesitant. Although this big guy can't move, it can't stand big enough, and everyone has to go to its stomach. Besides, who knows if this guy can't move?

Lin Xi took everyone's reaction in his eyes, and without much explanation, he ordered the soldiers to go back to the mobile base and bring supplies. Then Lin Xi used armor plates to set up brackets and passages in the center of the gate, once the door wanted to close, these armor plates were the support, not allowing the door to close.

Despite the excellent quality of the armor plates, the doors were too big, and no one had confidence in the 5 centimeters thick armor plates, looking at the small mountains of body tissue.

But then came the killer feature. Lin Xi placed boxes of explosives on the muscles that controlled the gate, and attached a large number of cutting blades. Once the explosives explode, tens of thousands of cutting blades will turn the muscles into meat floss.

After loading the explosives, everyone's hearts immediately settled a lot, and they followed Lin Xi and Chu Jun back to the depths of the passage.

There was almost no light in the passage, and the little natural light from the cave walls was very faint, and it could only illuminate the surrounding area for one or two meters in the dense fog. Standing in the middle of the passage, there is darkness in front of you. The armor's lights could only illuminate less than 20 meters ahead, and it was impossible to see where the end of the passage was.

Lin Xi turned on the sound wave detection system of his personal terminal, which would make a soft sound every second, and according to the echo, he could distinguish the general outline of the environmental object.

Since Lin Xi turned on the sound wave detection, Chu Jungui did not turn it on again. Two different sound sources will interfere with each other, and the subject can simply listen to Lin Xi's echoes.

The team continued to go deeper, and the two fighters on either side constantly swept the surroundings with specialized laser beams to prevent sneak attacks.

The passage was deep and long, and the subject silently calculated the distance, and walked a full 1,000 meters before another gate appeared in front of him.

This gate is exactly the same as the door at the entrance, Chu Jungui concocted it in the same way, interfering with the current in the door, and sure enough, the gate opened on its own, and the amplitude was about the same as the first door. Chu Jungui tried to interfere for a while more, the speed at which the door opened became slower and slower, and finally there was no response at all.

Lin Xi stopped moving forward, and waited for the explosives from the rear to be transported and arranged, and then continued to go deeper.

After walking a little further, everyone's eyes suddenly opened up, and an underground hall appeared.

The underground hall is extremely grand, and the interior is also full of fog, although it is not as bad as the line of sight in the passage, but it can only be seen dozens of meters out, and the opposite side cannot be seen at all.

Chu Jungui walked to the entrance of the passage and looked down, but he couldn't see the bottom at all, he could only see that there were several holes dozens of meters below, which should be passages to other places.

Chu Jungui looked at the curvature of the cave wall of the underground hall, and preliminarily estimated that the diameter of the underground hall was at least 2,000 meters. At this size, the mysterious black shadow was also within the confines of the hall.

The walls of the underground hall are very smooth and straight, and there are no stairs or platforms to be seen. And the edge of the exit of the passage is curved, and I don't know if it's natural or if it's been ground by something. That is, the subject can accurately grasp its own balance, so it dares to stand on the edge of the cave and look down, if it is replaced by someone else, one will accidentally slide down.

Chu Jungui thought about it, took an empty magazine, and threw it down. After hearing the echo, he said, "It's okay, about 100 meters over, not too deep." Wait for me here, and I'll go down and see. ”

Lin Xi immediately said, "I'll go with you." ”

"No, it's easier for me to move alone!" is the answer of the art component.

"No, you need to command here. This is the answer to the political component.

"No, you have to stay here, and if something happens, you have to be able to answer me. Tactical deception answered.

Chu Jungui instinctively chose tactical deception.

This is also quite a good reason, Lin Xi hesitated for a moment and nodded in agreement. She also knew that with Chu Jungui's skills, it was actually safer to act alone.
