The soft surface soil was dug up in turn by several armors, and their steel masters were the best excavation tools, especially the two special armors, sharp claws and even hard rocks could be dug out.︾

Digging all the way down until it could not be dug. The scorpion armor entered. The modified Vulcan cannon was tightly pressed against the rock. As soon as the fire signal was turned on, the Vulcan cannon that had removed the bullet link turned at high speed, causing the scorpion tail to quickly drill a big hole in the rock.

The diameter of the large hole is as wide as 70 cm, just enough to be stuffed into a glass detonator.

Multiple glass detonators with different attributes were stuffed in one by one, and a simple detonation device was pressed down on the end, and then the stone was blocked.

After finishing, everyone consciously retreated for a while without Zhang Qifan's instructions.

The detonation device exploded, and the impact force pushed all the glass detonators forward. The glass broke and the liquid inside merged together almost instantly.

Because it is pushed and fused together by the detonating device, the liquid gushed in the same direction before the fusion, and exploded at the moment of the fusion. Most of the power is also released towards the front, creating an effect similar to directional blasting.

A ball of flame exploded on the ground, and the nearby ground shook wildly, and a large amount of dust was sprayed into the sky. Although it was not small, it was completely different from the mushroom clouds that had been stepped on by the simple landmines before.

When the flames and dust dissipated, a large pit of thirty or forty meters appeared on the ground, with a depth of at least thirty meters.

Under Zhang Qifan's command, a leopard armor entered the pit and cleared out all the soil in the pit at the fastest speed. The scorpion retreated and drilled the hole again. The explosives were filled, and this was repeated. A tunnel with a diameter of thirty or forty meters and obliquely penetrated the ground gradually took shape.

Judging from Zhang Qifan's actions, Liu Ye actually had doubts. With the glass detonators on their hands, can they really break through an authentic tunnel that goes straight to the enemy base?

It is only 30 meters at a time, and only 300 meters are traveling back and forth ten times. There are so many giant turrets standing on the plain, and a solid foundation is needed, otherwise they will not need to attack. The recoil of the turret can collapse the plain by itself, so the thickness of the strata is likely to be more than 300 meters.

Besides, they will hit the target diagonally, and the distance required will be longer.

Liu Ye's doubts also arose in the minds of other commandos, but now they have lost contact with the warships, no one can give them orders, and follow Zhang Qifan at least has a clear goal and know what he is doing.

However, this doubt did not last long. With the fifth wave of explosion, a rustling sound suddenly sounded at the bottom of the pit. When I looked over, I saw a large amount of gravel and gravel rolling downwards. The end of the passage was pitch black and bottomless.

The tunnel seemed to have penetrated the rock formation and reached a large underground space.

Zhang Qifan greeted him in the communication channel and took the lead in getting into the tunnel.

Liu Ye and the other commandos hesitated for a moment, gritted their teeth and followed one after another. They crossed the pit. They entered a narrow and long underground space. The height of this space is only seventy or eighty meters, and the width is three or four hundred meters on the left and right. However, it extends downward obliquely, and I don’t know where it extends.

The tunnel they made was connected to the top of this space. The holes they made were almost the shortest route into this space. It is likely that it would take several more times if they were slightly off, just like watching a holographic map.

Liu Ye couldn't help asking: "Chen Wu, don't you have the ground-type data here? The location is so accurate? It's like watching a slap."

Zhang Qifan did watch and hit, but of course it was not because of the ground shape data, but because he could really ‘see’ through the strata. But this reason was obviously unreliable, so he could only agree with Liu Ye’s statement.

Under the leadership of Zhang Qifan, a total of fifty-three armors quickly passed through the narrow underground space. When they reached the middle section, Zhang Qifan pointed to an ordinary position and signaled the scorpion armor to dig holes in this place.

After repeating this four times, all the mines collected by Zhang Qifan were used up.

Once again, Zhang Qifan waved to Liu Ye.

When he came over, Liu Ye's ammunition and energy box were thrown away, leaving only ten drilling bullets on his body. But when his armor energy was full, he could only shoot five shots in a row. Now that he had run so far, the remaining energy could only fire four shots.

The warhead loading in the heavy magnetic drilling ground bomb is a tactical nuclear bomb with very powerful power. It usually fires a few dozen kilometers away. This closed underground space has no room for him to play. It is still a question whether the strata can penetrate if it is shot, but they are definitely in danger.

Seeing Zhang Qifan waved, Liu Ye walked over hesitantly, holding his heavy sniper and asked vigilantly: "What do you want me to do?" He made up his mind that if Zhang Qifan asked him to fire into the pit, he would definitely refuse.

Zhang Qifan took his heavy sniper, freed up all the ammunition, quickly removed the warhead, leaving only the ground-based warhead stuffed into the heavy sniper, threw it back to Liu Ye and pointed at the pit.

Without saying anything, Liu Ye knew what he should do. He stared at the demolished warheads and muttered: "This is OK..."

When the four guns went down, the heavy magnetic drilling warhead was like a pile driver. Each gun extended the pit for more than twenty meters. The four guns used up Liu Ye's armor's energy. Before he could stop, two full energy boxes were moved to his side.

Liu Ye's armor and the commando's armored energy box are both common. There are more than fifty commando armor here, each of which contributes a box of energy, which is enough for Liu Ye to shoot dozens of more cannons. Unfortunately, he does not have so many shells.

Four more guns went down, huh! Liu Ye felt something pierced through. The pit no longer surged back into a large amount of debris and dust like the previous few times. Instead, there was a kind of indescribable coldness that was gushing out of the pit, making Liu Ye shivering smartly.

"Damn it, it's so cold..." Liu Ye subconsciously retreated. As soon as he retreated for enough space, Zhang Qifan's armor rushed past him and drilled into the pit as fast as possible.

As Zhang Qifan entered the pit, the cold feeling that made Liu Ye tremble completely disappeared.

Other commandos asked questions from the channel: "How come it is cold? Is the temperature control of the cockpit broken?"

Yes, how could I feel cold? I am in the cockpit, is it an illusion?

Before Liu Ye could think about it, the commando's armor surrounded him, and their urging sounded from the channel: "Come on, keep up, hurry up."

When he was urging from the people behind, Liu Ye had no choice but to get into the pit and slid down. Not long after, he landed at the bottom of the pit. He raised his head and took two steps forward to get out of the bottom of the pit to avoid being hit by the armor that followed behind him.

But as soon as he raised his head, Liu Ye couldn't walk anymore and he was fixed there.

I saw a huge pyramid standing in the underground space in front. There were countless corpses around the pyramid buried the pyramid, submerging one-fifth of its height. (To be continued, please search for Piao Tianwen, the novel is better and faster!
