"Boss, what should I do?" Liu Guangsheng, who was standing beside him, looked back at the groups of barking pips slowly approaching behind. The nearest barking pips had approached within 30 meters of Qin Yang and others in the rear, and could launch an attack at any time.

The number of barks that appeared from the darkness exceeded sixty. They opened their green eyes and made roars of dogs barking from their mouths. The roars of dozens of barks mixed together, with a huge momentum, causing great psychological pressure to everyone.

This gray-white giant wall cannot be seen how high it is, and it is not clear that it is long. It is too late for everyone to bypass it. The only hope is to explode the huge wall, and there may be a glimmer of hope. Otherwise, when the groups of barking rush up, with the amount of ammunition left in everyone's hands, even if everyone can fight with it, there will be casualties.

Zhou Kesheng, Li Zhibao and others didn't speak, but 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 on the wall facing him, and did not answer Liu Guangsheng's words. He just quickly stuffed the assault rifle into his hand, then took out two bundles of explosives from his backpack and rushed forward.

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

"Everyone takes a step back." Sun Tao stuffed two bundles of explosives into the gap in the wall that had just been bombarded. While igniting the two bundles of explosives at the same time.

Everyone was busy retreating one after another, setting apart from the giant gray-white wall.

This specially made explosive is powerful, several times more than that of grenades. It is used to prepare for the use of giant mountain rocks in case of explosion, which is not as convenient as grenades, but the explosion is extremely powerful. At this moment, Sun Tao used two bundles at the same time. Even if the gray-white giant wall was cast with reinforced concrete, it could explode a huge gap and allow people to pass through.

As long as the gap is exploded, everyone can pass through it calmly and then hold it down. It is easy to defend but difficult to attack, so there is no need to worry about these groups of barking.

Everyone pulled apart from the gray-white giant wall. Seeing the eyes of the crowd of barking, it was like everyone suddenly rushed towards them. This was a provocative attack. Suddenly, there were continuous barking and roars. Immediately, dozens of barking roared and rushed up, shooting like sharp arrows in the darkness.

"Fire--" Qin Yang shouted angrily, Barrett in his hand made a loud bang, and the submachine guns in his hands made a slam.

Xiao Ling held a blood-stained saber in both hands and was ready for battle. As long as there was a barking gun rushing up to approach the team in the rain of bullets, he would take action without hesitation.

One-on-one, holding two sharp military waist knives, he was not afraid of such strange beasts barking.

Now he has had some experience in fighting against such dangerous beasts, and he is becoming more and more calm during the battle.

Groups of barking barking roared and rushed up in a fan shape, and Sun Tao was also running away from the gray and white wall at the same time.

"Lying down--" Sun Tao rushed out more than twenty meters and suddenly let out a loud shout. He threw himself into the first place. Zhou Kesheng, Li Zhibao and others were farther away. He heard Sun Tao's yelling and he threw himself into the air.

Then there was a loud roar, and the entire ground seemed to be shaking violently.

The barks who had just rushed up were also frightened. They didn't understand what was going on, and they stopped one after another. The barks retreated, showing panic and confusion.

Two bundles of explosives used to open the mountain and gravel exploded, and their power was amazing. After the deafening explosion, Xiao Ling looked up at the direction of the gray-white wall, and saw black smoke coming out of it. A huge black hole broke out on the wall, enough to allow two or three people to get in at the same time.

In the black hole, thick smoke was pouring 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 one after another and headed towards the giant gray-white wall.

A huge hole was blown out of the gray-white wall, and gray-white stone chips were scattered everywhere. Hu Shengzhe saw it and secretly praised him.

"The project of this giant wall is very large. Who made it? It seems impossible to be a modern man, but was there such a level of construction in ancient times? The material of this giant wall seems to be no less solid than concrete."

Out of curiosity, Hu Shengzhe picked up a few pieces of scattered white debris and put them in his pocket, preparing to study it carefully when he had time. Perhaps he could see from this material that the huge wall was from what age.

Sun Tao led everyone to rush towards the huge hole that was blown out. He turned on the spotlight and shone it into the huge hole in case there was danger inside.

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

Liu Guangsheng followed closely and was about to ask why he stopped, but suddenly he was stunned.

Originally, everyone thought that they could blow up a gap in the gray-white wall and go through the gap and continue to go down the Black Mountain. No one expected that after the gap was blown up, they would enter a huge closed space. This space was like a giant tunnel, with darkness on both sides so dark that it could not be seen.

"This...this is..." Sun Tao was a little confused, and everyone went in one after another.

There were again sounding outside, gunshots and barking whistles.

The frightened group of barking beasts launched another attack. Qin Yang led a dozen team members to retreat while fighting. As everyone entered the exploded wall gap, they also retreated to the edge of the gap.

Retreat to the gap, there is danger to defend, and there is no need to be afraid of the numerous barkings. Qin Yang breathed a sigh of relief and the pressure suddenly decreased.

He and a team member were guarding the gap, watching groups of barking piers approaching, and then took out a grenade and threw it out.

After the grenade exploded, three barking rods were killed, and dozens of other barking rods looked at the gap, obviously hesitating.

They are not stupid.

In the open area, they could surround them by relying on their numerical advantage. Now that everyone escaped into the gap in the giant wall, their numerical advantage cannot be used, and when they rush up, they will easily be killed and cannot effectively attack the enemy.

Qin Yang was relieved when he saw the groups of barking sluts stopping dozens of meters away and barking at them. Although they did not disperse, they did not attack for the time being.

Within the gap, everyone gathered together, watching the giant tunnel beneath it.

"Who was able to build such a giant passage in this Black Mountain? Not to mention the masterpieces of the Qin Dynasty people and Xu Fu and others back then." Wang Lei shook his head as he said.
