The stone blocking the cave entrance was blown away, and a thick smoke spread in all directions, filling the space near the cave entrance.*.*
Zheng Xiao stood up from behind the stone and took the lead to walk towards the hole created by the explosion.
The location they are in now should be underground. Along the way, they blew up no less than four or five rocks before they arrived at the entrance of this underground cave.
From under the stone couch of the Water Curtain Cave, Zheng Xiao and the others found a cave entrance. Although it was not the entrance to the underground cave, according to calculations, it should not be far from the underground cave.
In this way, some special forces members stayed to guard the entrance of the cave, while the remaining special forces members followed Zheng Xiao into the cave.
This cave was originally supposed to be a natural cave, but it was dug out later, so the space inside is very spacious and the ground is very flat, making it easy to walk up.
However, Zheng Xiao and the others walked forward less than 500 meters when they encountered an obstacle. This was a large stone slab with a thickness of 1.5 meters, which blocked the passage.
The stone slab was four to five meters high, two meters wide and one and a half meters thick. Even if there were many people like Zheng Xiao, they could not open it. In the end, they had no choice but to blast it.
The high-explosive guns in their hands were all provided by the Yanhuang Legion, and their power was astonishing. It only took a small piece as big as the belly of a finger to blow up such a large stone.
The products produced by the Yanhuang Army were indeed of high quality. Zheng Xiao praised them while leading the people to move forward. However, after 500 meters, they encountered the same stone slab again.
There was nothing to say, just keep blasting. Anyway, we brought enough explosives this time, so the special operations team members used these stone slabs to practice their blasting skills.
The muffled sound of booming and booming sounded every few minutes, five times in a row.
Finally, after the explosion, there were no stones blocking the way, and the passage was unobstructed and stretched forward, as if there was no end in sight.
Walking and walking, Zheng Xiao and the others walked for another half an hour, and finally reached the end of the passage. There was a stone wall in front of them, and the passage ended here.
Walking to the stone wall, Zheng Xiao stretched out his hand to touch the cold stone, then turned back and asked the special operations team members, "What do you think is behind it?"
The special forces members all shook their heads in disbelief, although they didn't know what was behind the stone wall.
Maybe it's a thicker stone wall, maybe it's the underground cave they're looking for, or something else. It seems that they can only be sure after exploding it.
Zheng Xiao thought for a moment, then stretched out his hand to stop the special operations team member who was about to install the gun, and then ordered, "Let the Pyros behind come up and prepare for support, and the rest of the people are ready to receive fire."
Although something might not happen, Zheng Xiao felt that it was better to be just in case, so as not to be blinded temporarily.
Finally, this time, Zheng Xiao deployed four Pyros from the base, mainly because of the crocodiles he encountered earlier. Perhaps the Pyros would be more effective in dealing with them.
Animals are afraid of fire, especially aquatic creatures such as crocodiles, which have a natural aversion and fear of fire. In this narrow cave where the aircraft cannot support it, the flamethrower can play a very powerful role.
Zheng Xiao calculated the direction and found that the current direction seemed to be consistent with the direction of the mysterious cave. Although the two were not necessarily connected, he had to be careful.
After all, he still hasn't figured out what happened in that cave, and the large number of crocodiles that suddenly appeared is an unsolvable mystery.
Four Pyros rushed up carrying gas tanks on their backs. They all wore fire masks and protective gear for setting fire, and they were holding nozzles in their hands. They looked very individual.
However, no one dares to underestimate them. The nozzle in their hands is definitely a nightmare. Once encountered, it will definitely make people desperate for life and death.
In the warehouse in Qingtangzhai, there are also twelve flamethrowing vehicles stored, which are usually used on the battlefield. The pressure equipped on them is enough to send the burning oil tens of meters, and the covered area will definitely be instantly
It turned into a sea of fire.
Seeing that the Pyro was in place, Zheng Xiao signaled to the engineers to install the gun. He led his men back to the Pyro, watching the engineers vigilantly.
These engineers are the same bandits who built roads and fortifications in Qingtang Village. They were later reorganized into the Longya Special Forces Brigade Engineer Corps. Currently, there are more than 1,500 people, hundreds of machinery and vehicles, and they have strong construction capabilities.
Skillfully fixing the high-explosive gun on the stone wall, the engineer turned around and ran to a safe place, then picked up the detonator and pressed two buttons.
As the red light flashed, a loud noise suddenly sounded from the distant stone wall, making the earth tremble.
Following the explosion of the high-explosive gun, the stones on the stone wall instantly fell apart and turned into pieces of rubble.
The engineer did not move. He arranged several continuous explosions, and now one exploded, followed by a series of others.
Sure enough, the bombs exploded one after another, and the stones on the stone wall fell off one by one, continuing to extend deeper.
After a total of ten explosions, the high-explosive bomb was basically at its end, and the last one with the highest yield did not explode.
The yield of this high-explosive bomb was the sum of the previous ones, and it was much more powerful. Therefore, Zheng Xiao and the others all lay down and hid behind the rocks in the distance.
The engineer touched the detonator with his finger, set a delay, and then shrank behind the stone.
Three seconds later, the high-explosive gun exploded, and a loud bang that was many times louder than before roared in the cave, and a huge air wave swept far away.
Even when he was hiding behind a thick boulder, Zheng Xiao felt the suffocating pressure, but fortunately, it disappeared as quickly as it came.
Zheng Xiao raised his head from behind the stone and looked towards the opposite side. He found that the stone wall had been blasted into the stone wall for more than ten meters. At this time, thick smoke was still rising from the innermost part.
"Wait a moment, wait until the smoke clears before going in." Zheng Xiao thought for a while and decided to wait a moment.
People waited patiently. After more than a minute, the smoke became much lighter, and Zheng Xiao led two special forces members towards the stone wall.
Inside the cave where the stone wall was blasted, there were stones scattered everywhere, making it a bit stumbling to walk up. Zheng Xiao and the others walked through the stones and reached the depths of the stone wall.
Here was the final success of the explosion. Zheng Xiao stood in front of the stone wall and touched the stone that was turned black by the smoke.
Hmm? Weird?
Zheng Xiao glanced at the remaining stone wall, and suddenly his eyes froze, staring at the stone wall. Beside him, the two engineers were also staring at the stone wall, their faces full of surprise.
