At this time, Zhuo Yifan already had an extra high-explosive mine in his hand.He weighed it in his hand, and then asked the master of the Zhuo family: "How powerful is this high-explosive mine? Can this wall be blown up?"

"This... depends on how thick the wall is! It is a conventional high-explosive mine, and the killing radius is the most effective within 15 meters. If it is further away, even if it spreads, it will not have much effect! It is not an ordinary wall, it is It's definitely unstoppable! I just don't know how this wall is?" The master of the Zhuo family explained hesitantly.

Hearing this, Zhuo Yifan couldn't help frowning, and then motioned everyone to retreat 15 meters away.After all, except Zhuo Yifan, Qingyan, and Ryan, the three top experts who can not be afraid of the damage of high-explosive mines, but the rest of the mid-term experts do not have such terrifying internal strength as the protection of Zhuo Yifan and the three.If you are bombed, you will be seriously injured if you don't die!

After everyone retreated to a relatively safe position, Zhuo Yifan stood only five meters away from the wall and threw the high-explosive mine directly in his hand.

There was a loud "boom", and there was a burst of dust at the scene.The ejected clods and debris shot everywhere in the passage.Everyone felt the violent shaking under their feet, but it subsided quickly.

Most people are outside the safe range, so naturally they don't need to worry too much, but what they worry about at the same time is Zhuo Yifan who is the closest to the explosion point.

At this time, Zhuo Yifan, like a normal person, stood with his hands behind his back, squinting his eyes to observe the wall that was just blasted by high-explosive mines.

A large circular pit suddenly appeared on the wall.Presents a concave hemispherical shape.A large piece of steel bar exposed in the middle has been twisted and deformed by the power of the explosion!

But what made Zhuo Yifan's pupils shrink was that the depth of the concave line was about 40 centimeters, and it failed to blow through the wall.If the thickness of the remaining part is not enough to bear the power of the shock wave, even if it is not blown through, it will be broken because it cannot support it.But the wall showed no signs of cracking or piercing except for a recessed piece, which surprised Zhuo Yifan.How thick this wall is, one can imagine.The remaining thickness behind this may still be above the thickness that was blown!

"Such a thick wall! What is it for?" Ryan couldn't help but widen his eyes, showing a surprised expression.

"Ghost knows!" Zhuo Yifan snorted angrily, then walked a few steps, came to the bombed wall, and examined it carefully.

"Do you want us to continue bombing? Maybe with a few more grenades, it will blow through!" Ryan made a suggestion to Zhuo Yifan.

"Do you know how many walls like this are here? How many grenades do you have to waste? Do you think grenades don't cost money?" Zhuo Yifan asked angrily.

Ryan curled his lips, snorted coldly and didn't speak again.

The scene fell into a brief silence.Everyone is frowning, obviously full of worries about the current situation!Encountering such weird problems just after I came in, really discourages people's enthusiasm!

Just when everyone was bowing their heads and thinking about countermeasures, suddenly a strange voice came from the wall.It was a slight crackling sound.Although it was very light, with Zhuo Yifan and the others' ears, they could naturally hear it very clearly.But slowly, the slight noise gradually became louder.
