"Boss, what should I do?" Liu Guangsheng, who was standing beside him, glanced back at the group of barks that were slowly approaching in the rear, and the nearest bark had approached within thirty meters of Qin Yang and the others in the rear, and they could attack at any time.

The number of barks that emerged from the darkness had exceeded sixty, one by one with green eyes open, and the roar of dogs coming out of their mouths, and the roars of dozens of barks were mixed together, and the momentum was huge, causing great pressure on everyone's hearts.

This gray-white giant wall can't see how high it is, let alone how long it is, it's too late for everyone to bypass it, the only hope is to blow up this giant wall, maybe there is a glimmer of life, otherwise when the hordes of barks rush up, with the amount of ammunition left in everyone's hands now, even if everyone can fight with it, I'm afraid there will be casualties.

Zhou Kesheng, Li Zhibao and others didn't speak, just looked at Sun Tao, at this time, they could only count on him and these team members.

Sun Tao looked at the gap that the assault rifle blasted out in the oncoming wall, and did not answer Liu Guangsheng's words, but quickly stuffed the assault rifle into his hand, then took out two bundles of the most powerful explosives from his backpack and rushed forward.

Everyone understood that Sun Tao wanted to use explosives to blow up the white giant wall.

"Everybody took a step back." Sun Tao stuffed two bundles of explosives into the gap in the wall that had just been blasted out, and while drinking at everyone, he ignited both bundles of explosives at the same time.

Everyone hurriedly retreated, widening the distance between themselves and the huge gray and white wall.

This specially made explosive is huge, more than several times more than the grenade, it is used to prepare for the need to blow up the mountain boulder, it is not as convenient to use as the grenade, but the explosion power is extremely great, at this moment Sun Tao used two bundles at the same time, even if the gray-white giant wall is cast with reinforced concrete, it can also blow up a huge gap, allowing people to pass through.

As long as the gap is blown open, everyone can pass calmly, and then hold the gap, which is easy to defend and difficult to attack, so there is no need to be afraid of this group of barks.

Everyone widened the distance from the gray-white giant wall, and looked at the eyes of this group of barkers, which was equivalent to the crowd suddenly rushing towards them, this was an act of provocative attack, and immediately there was a continuous roar, and immediately, dozens of barking roared and rushed up, shooting like sharp arrows in the darkness.

"Fire-" Qin Yang shouted angrily, the Barrett in his hand made a loud bang, and the submachine guns in the hands of several team members beside him made a clicking sound.

Xiao Ling held a blood-stained saber in both hands, and he was ready to fight, as long as there was a bark rushing up to approach the team in the rain of bullets, he would not hesitate to strike.

One-on-one, holding two sharp military waist knives, he was not afraid of this strange beast barking at all.

Now against this dangerous beast, he already has a certain amount of experience in fighting, and in the battle, he is becoming more and more calm.

A group of barking roared and rushed up in a fan-shape, and Sun Tao also ran away from the gray-white giant wall at the same time.

"Lying down-" Sun Tao rushed out of more than 20 meters, and suddenly let out a loud shout, he fell down first, Zhou Kesheng and Li Zhibao and others were farther away, and they heard Sun Tao shouting loudly, and they fell down one after another.

This was followed by an earth-shattering bang, and the entire ground seemed to shake violently.

The barking that had just rushed up in a group was also frightened, and they didn't understand what was happening, so they immediately stopped, and some of them retreated, showing panic and confusion.

After the deafening explosion, Xiao Ling looked up in the direction of the gray-white giant wall, and saw that there was black smoke there, and a huge black hole was blown out of the wall, which was enough for two or three people to get into it at the same time.

Inside the black hole, smoke billowed out.

"It's done!" Sun Tao jumped up first, very excited, took the assault rifle that had just been handed over to Liu Guangsheng, and rushed towards the huge black hole.

The others stood up and headed for the massive gray-white wall.

The gray-white giant wall was blown out of a huge hole, and gray-white stone chips were scattered everywhere, Hu Shengzhe saw it in his eyes and was secretly surprised.

"The work on this huge wall is huge, who built it? It seems impossible to say that it is modern people, but was there such a level of architecture in ancient times? The material of this huge wall seems to be as strong as concrete. ”

Out of curiosity, Hu Shengzhe picked up a few pieces of this scattered white debris and put them in his pocket, ready to have time to study them carefully, maybe he could tell from this material what age this giant wall came from.

Sun Tao led everyone to rush to the huge hole that was blown out, and he turned on the searchlight to shine into the giant hole, in case there would be danger inside.

After Sun Tao rushed in, he stopped again, with a stunned look on his face.

Liu Guangsheng also followed, and just wanted to ask why he stopped, but he was suddenly stunned.

Originally, everyone thought that after blasting this gray-white giant wall into a gap, they could continue to go down the Black Mountain, but no one expected that after the gap was blown open, they would enter a huge enclosed space, which was like a giant tunnel, and there was no end in sight on both sides.

"This ...... This is ......" Sun Tao was a little blind, and behind, everyone got into it one after another.

Outside again, there was the sound of gunfire and barking.

The frightened barking beasts attacked again, and Qin Yang took a dozen or so team members, retreating while fighting, and as everyone got into the gap in the blasted wall one after another, they also retreated to the edge of the gap.

Retreating to the gap, there is a danger to defend, and there is no need to be afraid of the large number of barks, Qin Yang breathed a sigh of relief, and the pressure suddenly decreased.

He and one of his teammates stood at the gap, watched as a horde of barking approached, then took out a grenade and threw it.

After the grenade exploded, three barks were killed, and dozens of other barkers looked at the gap, apparently hesitating.

They're not stupid.

In the past, in the open area, they could rely on their numerical superiority to surround them, but now that everyone has fled into the gap in the giant wall, their numerical superiority cannot be brought into play, and if they rush up again, they will be easily killed, unable to effectively attack the enemy.

Qin Yang was relieved to see that the group of barks stopped dozens of meters away and barked at them, although they did not disperse, they did not attack for the time being.

Within the gap, everyone gathered together and looked at the huge tunnel that was a little blindfolded.

"Who could build such a giant passage in the middle of this Black Mountain? Not to mention the masterpieces of Xu Fu and their Qin Dynasty back then. Wang Lei shook his head as he spoke.

Such a huge passage is not an overnight effort, and the project is huge. It is a modern building, but this Montenegro and this sea area do not exist on the nautical charts, let alone this possibility.
