The people of Boundary Island are on alert. Ancient Source Crystal is a good thing, but it is also a very dangerous thing.

Once the ancient source crystal is affected by some external force and becomes unstable, it may explode violently.

There was once a member of the Boundary Island who was unlucky enough to encounter an attack from a Tianyuan realm creature in the jungle. In a panic, he actually used his supernatural power to attack an ancient source crystal the size of a fingernail that he was carrying.

Then, the ancient source crystal exploded violently, and the Tianyuan realm creature was enveloped in the explosion, leaving no body behind.

This shows that this ancient source crystal can be used as a very powerful weapon.

They had never seen a fist-sized ancient source crystal before, and they didn't know what the red ancient source crystal meant. They just instinctively told them that this thing was very dangerous!

Zhang Mengyu spent a long time groping around on the Italian cannon, but he still couldn't find a place to fill it with ancient source crystals.

"Damn, how do you use this thing?"

"Damn it, you don't know how to show off with your show?" Wang Ling was speechless, "I've thought about all the sexy things to say, I've even taken off my pants, and you just show me? Are you embarrassed?"

"As long as I'm not embarrassed, you will be the ones embarrassed!" Zhang Menglong said with a smile, "Wait a minute, I'll look for the instructions!"

...

"Teacher, I think we are too nervous?"

"Is it possible? This thing doesn't look very powerful."

"Perhaps we are making too much fuss. How can there be weapons that can break our barrier?"

"It's just that it's so inconvenient to use. You can tell at a glance that it has no high-tech content."

Seeing Zhang Mengyu's operation, the people on Jie Island felt an inexplicable sense of security.

...

"Forget it, it's gone!" Zhang Mengyu took out the instruction manual directly through the dean's ring. He compared the instruction manual and finally found a switch.

"Crack!" An energy tank bounced out of the Italian cannon, leaving just a groove big enough to place the fourth-level crystal core.

Zhang Mengyu put the crystal core into the machine behind the barrel. In an instant, a red light filled the air. This force was far ten times more powerful than the force that Wusi erupted when he attacked the barrier...

..

"Woof woof woof!" Wangcai shouted at the Italian cannon. He was extremely intelligent and knew how powerful this thing was.

Wusi also trembled and hid behind Wangcai. It seemed that in front of this force, only its boss Wangcai could give it some sense of security.

It's not like Zhang Mengyu has never seen how terrifying 40 units of energy can be. When he used the power of Yao Chen to kill Hui Jieyan Er, the guy's energy was as high as 42 units.

But this is almost the huge difference between technological weapons and human cultivation. In terms of momentum, technological weapons are more terrifying!

"Back off! Back off!" Tong Xiao shouted loudly. As a Tianyuan realm warrior, no one could feel the terrifying power contained in this cannon better than him.

When did humans invent such a terrifying weapon? It had been five or six years since he last left the island. Have human weapons made such great progress in just five or six years?

Is this the legendary technological explosion?

"Will this barrier really be broken?" Tong Xiao questioned the barrier on Boundary Island for the first time.

"Everyone, cover your ears, we're about to fire!"

Zhang Mengyu was the first to pull Lu Yiyao and hide behind a big tree dozens of meters away.

The instructions for use of this Italian cannon say that when using a crystal core of level 4 or above, those who have not reached the Tianyuan realm must stay away for more than 20 meters.

"Fuck! Tell me earlier!" Wang Ling also quickly pulled Jiang Qiyuan away.

"Woof woof woof!" (Little brother, follow the big brother!)

...

The red light became more and more dazzling, almost covering the entire 10-meter radius.

A moment later, with a deafening loud noise, the entire barrel shook violently, and even the ground cracked with fine cracks.

A huge red energy beam hit the barrier directly.

"boom!"

It was as if the entire island was trembling. The invisible barrier was actually rippled with red ripples by the power of the Italian cannon. The strong energy was tearing at the barrier, making a crunching sound.

"Crack!"

Suddenly a crack appeared in the sky.

The crack began to expand rapidly, widen, and then spread along the entire island, as if it would be completely shattered at any time.

The roar of the Italian cannon lasted for a full 10 seconds, until all the energy was exhausted and the red light slowly extinguished.

At this moment, in the sky over the entire Boundary Island, the barrier has been reflected by a red force. It has become extremely fragile, as if it only needs one more blow to completely break it.

"Boom!" A loud noise came from the depths of Boundary Island, and then, the crack began to recover at a speed visible to the naked eye!

But no one knew that on the thousand-meter-long ancient tree in the center, large tracts of leaves began to wither.

Ever since there were traces of humans on this island, this ancient tree has never withered.

The power of this barrier comes from that ancient tree, which is using its own power to repair the barrier!

At this time, none of the people on Boundary Island could remain calm. Tong Wei's arms and legs were trembling. The shot just now really almost broke the boundary of Boundary Island!

But fortunately, their patron saint did not let them down, and the barrier still stood firm, helping them block this terrifying attack.

"This thing is really powerful!" Zhang Menglong couldn't help but sigh. The energy impact of 40 units could level even a small town, but it was actually blocked by this barrier.

"You have tried it too. Your strength cannot break this barrier. Give up!"

"Who said we can't break it?" Zhang Mengyu took out ten level 4 energy crystals and a level 5 energy crystal core from his body. As long as these things are not used, they can be returned to the Super Seminary.

Counting.

"Ten...he still has ten such ancient source crystals?" At this moment, Tong Wei, who was still complacent just now, was dumbfounded.

The power of this piece of red ancient source crystal almost shattered their boundary island barrier. If it were ten times more powerful, would it directly destroy the entire space?

Especially that black ancient source crystal, even though it was hundreds of meters away, he could actually feel a power full of death and destruction from it.

"This is probably scarier than the red one!"

"Forget it, it seems a bit boring to use this!" Zhang Mengyu actually put away all the Italian cannons and those energy crystal cores at this time.

"What are you doing? Why did you put it away?" Wang Ling asked curiously.

"I think this matter in the ancient martial arts world should be solved through the ancient martial arts world's methods. What's the point of using high-tech weapons?"

"That's not unreasonable," Wang Ling nodded, "Then what are you going to do?"

Zhang Mengyu stepped forward, twisted his neck, and made a rattling sound.

"Didn't you just ask me where I studied?" Zhang Mengyu said to Tong Xiao, "I am indeed self-taught, but you may not know that I am not studying ancient martial arts."

"Not ancient martial arts? Are you a superpower? Or a mutant?"

Everyone knows that practicing ancient martial arts cannot be achieved quickly.

But people with superpowers are different. Some people who are born with special physiques may have the power that ancient warriors only have after decades of practice when their superpowers are activated.

Maybe Zhang Mengyu is a freak!

"No!" Zhang Mengyu shook his head, "Actually, we are cultivators of immortality."

"Have you ever heard of a saying that martial arts practitioners should never mess with immortal cultivators?"
