The Era of National Martial Arts

"How is it, Brother Lu?" Mu Jianfeng asked.

Lu Min pondered and said, "It is indeed hollow, and the inside is empty. I don't know what is inside."

After saying that, Lu Min looked at Geng Huan.

Geng Huan was taken aback, and smiled wryly, "I really don't know what's inside, and that's how I realized that the rock wall is actually hollow."

"Um……"

Lu Min nodded, he also didn't believe that Geng Huan would know and not report.

"Brother Lu, maybe you can roughly measure the distance?" Mu Jianfeng said after thinking for a while.

"No, you can't feel it, can you?"

Lu Min said, "Not only that, I even feel that I can't shake this rock wall."

Mu Jianfeng was taken aback, and without saying a word, he clapped his hands.

This time I almost gave it my all.

However, it was almost the same as before, only a little more sand and gravel fell, and nothing else changed.

Mu Jianfeng's face changed slightly, and he said in shock, "It's true, the previous three-point strength is almost the same as the eight-point strength just now, it's really weird."

At this time, Lu Min came over, pinched a rock, and squeezed it hard, but it didn't break immediately. 11 Friends who read books, you can search for "Blue Chinese Network", and you can find this site at the first time.

=== Chapter 280 Combat Readiness ===

"what?"

Lu Min let out a light snort, staring at the rock in his hand, and exerted a little more force before barely crushing it.

"what happened?"

Mu Jianfeng came over and asked with a slight frown.

Lu Min put the broken rock in his hand in front of Mu Jianfeng, and said, "This place is really weird, I couldn't crush it just now."

Hearing this, Mu Jianfeng was greatly surprised, and went to the rock wall to take a stone.

Like Lu Min, after a while, the strange color in his eyes became more and more intense.

"Sure enough, the rock surface here is the same as the outside world, but it's hard to crush. It's really weird."

Mu Jianfeng was very surprised and said.

Even as an eighth-rank martial artist, he has rich experience, but he has never seen this kind of rock.

Thinking of this, Mu Jianfeng mobilized his blood and slapped hard on the rock wall.

Even with [-]% of the force, only a rock the size of a head can be removed.

Then, Mu Jianfeng handed the rock to the group behind him, and said, "Take this stone back and study it, and see what the composition is that can withstand the strength of the master."

"Shall we try together?"

Mu Jianfeng looked at Lu Min and suggested.

Lu Min narrowed his eyes, and said to Xu Zhen and others behind him, "Stand back!"

After speaking, Lu Min didn't say much.

Mu Jianfeng smiled wryly, turned around and said, "Retreat outside, we will try our best later, it may be dangerous, so it's better to go out to avoid accidental injury."

Xu Zhen nodded, turned around and left without saying a word.

He didn't want to be shocked to death by the aftermath of his master.

That's probably a joke.

A group of people walked out of the cave deep in the vein.

It was several miles away before stopping.

"Xu Zhen, why did you go so far?"

Being so cautious towards Xu Zhen, Geng Huan was quite speechless.

Before Xu Zhen could explain.

There was a sudden shaking in the mine vein, and then, a deafening loud noise came over.

"Fuck, it's so powerful even after being so far away?"

Xu Zhen swayed from side to side, squatted down immediately, and gradually kept from falling.

After a while, everything slowly returned to calm.

Xu Zhen raised his head, his eyes filled with deep shock.

It was at least a few miles away from Mu Jianfeng and the others.

In order to avoid being accidentally injured, Xu Zhen walked a long way.

Unexpectedly, he still couldn't escape.

Geng Huan was much better than Xu Zhen, he wasn't in such a mess, and he was still a fourth-rank martial artist.

"It seems to have stopped, let's go and have a look."

Xu Zhen's curiosity gradually arose, and he went to the depths first.

A group of people followed Xu Zhen closely, all of them became curious.

Not long after, the group of people looked at the scene inside and couldn't help being dumbfounded.

At this moment, it was a mess inside.

Xu Zhen walked in immediately, ignoring the messy ground, but looking at the rock wall.

Immediately, Xu Zhen's pupils shrank suddenly, and he muttered, "The two great masters failed to cause substantial damage, which is too terrifying.

What the hell is this material that can be so hard? "

Not only Xu Zhen was surprised, but Mu Jianfeng and Lu Min were also surprised.

The two of them can be said to be the strongest in Wancheng, but they can't do anything to a rock wall. If they say it, they will be laughed out of their teeth, which is too shameful.
