Shi Peng also sent people to explore the underground before, but he didn't have time to widen, and there was an emergency light every 100 meters, this light was like a firefly at night, the symbolic meaning was greater than the actual meaning, and he could fall if he was not careful.

This is an underground space several kilometers long, the widest is less than 500 meters, the narrowest is more than 10 meters, the ground drop is not large, but there are countless cracks, many of the gaps between the ground is less than a foot wide, some of the cracks on the ground there are more small cracks, I am afraid that it will collapse if you go up.

People who have explored before have also marked the danger symbol here, each gap is a route, but not all routes are safe, to be precise, most of the routes are not safe, some of the knife-edge roads have been missing, many routes need to be halfway first, and then bypass the side, although only two or three kilometers, but like a maze.

Seeing this, Gao Feng was a little entangled, and there was no problem for a small number of people to pass, but he had two thousand soldiers, what if?

The knife-like trails are winding and long, many of the trails are divided into two or three in front of them, and there are very narrow passages that have been gathered by other trails in the process of extension, and finally form avenues, just like the roots of two big trees are entangled with each other, and the blank space of the roots is a bottomless cliff, once it falls, it is a place to die without a place to be buried.

"Let the brethren tie themselves together with ropes......

Can't advance or retreat, Gao Feng gritted his teeth and made a decision, one person may fall, but there will be no ten people falling, right?

Gao Feng naturally doesn't need a rope, he takes the lead in the front, carrying two heavy backpacks, Gao Feng is equivalent to the volume of two people, as long as he can walk over, the people behind can walk over.

The narrow gravel passage made countless slight explosions at the foot of the peak, and grains of sand fell off the sides of the narrow and steep roadbed under his feet, and the peak walked forward step by step, twenty meters behind him, and the endless line followed.

Twenty meters is a safe distance reserved for the peak, and even if something happens, it is impossible to affect the back.

Walking on the narrow roadbed with fear, the peak always pays attention to the changes around him, the eagle eye spent a lot of effort, the high jīng degree night vision device smuggled out from the army allows the peak to see even the narrowest cracks, many seemingly solid road surfaces are actually full of cracks, the peak can only advance three and retreat two, and keep detouring.

In the high tension, Gao Feng walked nearly half the distance, looking back and back, the long line was like a twisted snake, stretching to the end of the last part, and I don't know how many people in the road have not yet stepped on the narrow road, because of the detour, they can never walk in a straight line, so it looks like a strange pattern depicted by the black sè line.

At this time, Gao Feng was slightly relieved, at least the road base was stronger than he imagined, turned around and continued to walk forward, and the Zhilu Dao turned around, the ground under his feet suddenly sank, and the whole person rushed forward.

"Broken ......."

I screamed in my heart, but my footsteps jumped forward quickly, jumping out of a distance of three or five meters every time, but what I didn't expect was that this jump was even worse, he was carrying two backpacks and the weight of the jump, so that the roadbed in front of him exploded like an explosion, and then the entire roadbed began to collapse, as if a big snake rolled, the stretch of roadbed was shattered, and the collapsed roadbed behind the peak was like a fierce monster chasing after him, and the soldiers behind him exclaimed, and the collapsed roadbed was a hundred meters away.

Gao Feng finally found a roadbed that would not collapse, but saw a huge crypt with a radius of 100 meters behind him, and the collapsed roadbed just now also caused the surrounding cracks to collapse, and under the interaction, the entire ground has lost 80% of its foothold.

That is to say, Gao Feng was isolated from the two thousand soldiers behind him, although there were still some cracks around the crypt, but those cracks were less than the size of a palm at the widest, and the soldiers with heavy equipment were even more unbearable to step on, which made Gao Feng suddenly worried.

Although Gao Feng has a way to go back, but more than 2,000 soldiers stuck in the middle of the gap are not easy to do, once there is another accident, the two brigades will lose at least 30% of the population, just when he was bored, a person suddenly shouted from behind him:

"Don't move, don't move, it's already brittle underneath, and everyone will fall down if they move......

This shout reminded Gao Feng of Wudao's loud cry a few days ago, and there was no doubt that the person who shouted was Wudao who was mixing in the middle of the team to make soy sauce.

Spreading his wings, in the surprised eyes of Wudao, Gao Feng flew around the team, and saw at a glance that the roadbed under everyone's feet had also appeared more cracks because of the previous large-scale collapse, and where the cracks did not open, large and small gravels were falling off.

At present, it has reached the most embarrassing situation, and it is not far from a desperate situation, which makes Gao Feng depressed and wants to scold, and before he officially enters the eastern wilderness, these problems appear, which makes him suddenly impetuous.

"Great Elder, Great Elder, why did you stop ...... ahead?"

Don't ask the pole from the communicator on your shoulder, as the deputy regiment commander, the pole is also in the sequence of the expedition, the two of them are one head and one tail, and the communicator is only equipped with the squadron leader and above, and it can communicate within five kilometers for a short distance.

"It is forbidden for the team to make noise, no one is allowed to speak without an order, let the people behind rest temporarily, something ...... a little thing."

Gao Feng took a deep breath and calmed himself down, the problem now is not that he can't get over, but that nearly a thousand people are stuck in the middle of the middle and may lead to huge casualties, and people's panic is the biggest disaster.

"Great Elder, do you want someone to withdraw first, let's sum it up?"

The pole also knew that the road was not good, so he couldn't help but suggest, but Gao Feng knew that the moment was the time when morale was at its strongest, once it was withdrawn, there might be more problems, and the battle plan was also arranged, and if there was an accident, it would cause problems on the side of the Heavenly Claw army.

"No, it'll be solved quickly, give me half an hour to ......." Gao Feng looked up at the oppressive rock wall above him and said.

The climbing rope is a necessary equipment in the peak team, and there are many pitons with the climbing rope, which was originally used as a necessary tool to climb over the cliff, but it is just right to use it here.

The team that followed closely behind Gao Feng didn't make a sound, they didn't talk to each other, they didn't want to cause trouble to Gao Feng, but their legs and stomachs were trembling, even if they were all jīng sharp warriors who drank blood with knives, they were afraid of falling into the abyss and dying without a corpse.

Fortunately, Gao Feng did not sit idle, flapping his wings to find the lowest cave roof, and digging small holes with the teeth of magma behemoths.

When a rope hundreds of meters long was pulled by Gao Feng to the opposite side, a new passage was officially established, but Gao Feng was still uneasy, and the steep roadbed on the opposite side also cracked, and if he was drawn from the opposite side, it would not be possible to make the roadbed collapse again.

Gao Feng thought of a lot of ways, and finally decided to use the clumsiest method.

The solution was to lose the ability to fly in the cave, melt all the metal, embed it in the cracks in the rock roadbed under its feet, and dissolve the metal it carried, but also collected more than 200 shields, more than 500 daggers, and other metal equipment carried by many soldiers, and strengthened the roadbed on both sides, which prevented a new round of collapse.

The road was opened when the first warrior slid on a pulley from the opposite side, and in this way, the team was back on the road, but the road ahead was still not easy to walk, and the shields were relayed from the back to the front, and then turned into liquid in Gao Feng's hands, covering the cracks in the roadbed beneath his feet.

In the end, after Gao Feng led more than 2,000 people to an underground space where he could temporarily rest, none of the more than 1,500 shields in the team remained, less than 10 of the more than 2,000 daggers remained, and all the iron pots, buckets and other hot water utensils were gone.

The army of the peak can use the nutritional pills they carry as food, but in the field, drinking water still needs to be boiled before drinking, so that the army has no hot water to drink.

It was impossible for Gao Feng to go back to the rear to retrieve the metal again, and the team of 2,000 people was as crowded as an ocean in the small underground space.
