Liu Chao stretched out his right arm and gently shook it in the direction of the two metal semicircles.

Suddenly, a larger metal ball appeared out of thin air, enveloping the two semicircular balls inside.

The round metal ball has a diameter of 1 decimeter and is grayish-white in color.

Seeing this scene, Li Di was a little confused, so he couldn't help but look at Luo Nian beside him, and wondered, "Liu Chao, what is this for?" Playing with Blood Drops? ”

"I don't really understand! He did it for his own reasons. Luo Nian shook his head slightly, he also couldn't see through Liu Chao's approach.

However, Chu Ru, who was not far away, was not so calm, and hurriedly beckoned Luo Nian and Li Di to leave here.

Seeing Chu Ru's panicked look, Luo Nian and Li Di did not hesitate, and then rushed to Chu Ru's side as quickly as possible.

After the two of them were inside the high-level defense array, Chu Ru breathed a sigh of relief, "This Liu Chao is too reckless, if you don't agree with each other, you will make a big move!" ”

"It's just a metal ball, what's so strange, I can too!" Li Di muttered in a low voice, he was in the clouds at this time.

As soon as Li Di said this, Chu Ruke was not happy, and immediately glared at him viciously, "If you talk more, I will throw you out!" ”

Hearing this, Li Di had no choice but to scratch his head helplessly, and instead stared at Liu Chao in mid-air.

"Is it really that serious?" Luo Nian stroked Chu Ru's cheek and said gently.

"Well, it's serious, but inside the circle, it's okay, hehe!" Chu Ru's cheeks flushed.

......

On the battlefield!

Liu Chao stared at Tianhe in front of him expressionlessly, like a dragon looking down on an ant.

With Liu Chao gently waving his right arm forward, in an instant, the metal sphere in front of him sped towards Tianhe at a speed of 250 meters per second.

It's terrifying!

Seeing this, Tianhe smiled coldly, and immediately manifested a ten-meter-thick ruby wall in front of him.

The walls are translucent and glowing crimson.

So defensive, impregnable!

"No matter how dense the metal is, I will still break it!" Tianhe said indifferently, his face full of disdain.

Liu Chao's face was like frost, and he did not have a trace of emotional fluctuations due to Tianhe's conceit.

Just as the metal ball was about to collide with the ruby wall.

Tianhe thought that Liu Chao would catch up and break through his defenses with a denser metal.

But Liu Chao's next move greatly surprised him.

Because Liu Chao not only did not attack, but quickly withdrew at an extremely fast speed in the opposite direction to the metal ball.

During the evacuation, he did not forget to manifest dozens of metal walls glowing with silver light behind him.

Each metal wall is 20 meters long and wide, and has a staggering 5 meters thick.

Looking into the distance, the walls are lined up in an orderly manner, like a long dragon standing towering between Liu Chao and Tianhe.

The magnificence speaks for itself!

After pulling away far enough, Liu Chao turned to the side slightly, and then shook it hard in the direction of Tianhe.

Rumble!!! Prosperous!!!

Suddenly, a blinding bright light lit up from the metal sphere in front of Tianhe.

The light was bright, brighter than 10,000 suns combined.

It seems to break through this space and replace this sky!

In an instant, the swaying wind carried thousands of degrees of heat and swept across the land at several times the speed of sound.

What is touched, annihilated!

Under the violent impact, the metal wall manifested by Liu Chao was like paper paste, broken inch by inch.

Fortunately, Liu Chao evacuated in advance, and if he was in the center of the explosion, he would definitely be dead.

At this moment, Tianhe, who must be at the point of the explosion, has turned into a rain of light.

Even if he is strong, even if he is indestructible.

In the face of the destructive power that destroys the withering and decaying, all beings are equal!

And Luo Nian and the others, who were in the high-level defense array, could clearly feel that the earth was shaking violently, and the scorching heat was constantly baking the walls of the array.

If it weren't for the high-level magic circle to isolate the energy waves from the outside world, the three of them would definitely be burned by the high temperature of more than 6,000 degrees, not to mention the super shock wave that was several times the speed of sound.

What is this earth-destroying energy?

Over time, when everything calmed down, a huge mushroom cloud appeared at the center of the explosion, several kilometers high.

In the face of this devastating force, even the yellow-level magic circle arranged by Tian Mo was gone at this moment.

It's terrible, just one blow, the mountains and rivers collapse!

As far as the eye could see, there was no life in the area shrouded by the gravity circle, and even the towering ancient trees that had risen from the ground had already disappeared.

It is precisely because of the blocking of the gravity circle that the explosion range will not be expanded to the extreme, otherwise there will be no grass within a radius of ten kilometers.

When I looked closely, a terrifying hole tens of meters deep and hundreds of meters wide appeared in the ground.

"This? This? What the hell is going on? Li Di was instantly dumbfounded, fortunately, he had the protection of the defensive array, otherwise he would have gone to meet Tiantong at this moment.

"Is this a nuclear explosion? Abbreviated as the atomic bomb! Luo Nian said with a solemn expression.

"That's right, this is a nuclear explosion that shocks the earth and weeps ghosts, fortunately, there are not many plutonium-239 manifested by Liu Chao, otherwise, even if it is protected by a high-level defense array, it will be difficult to resist the shock wave generated by the explosion!" Chu Ru explained with a smile.

"Plutonium-239? Isn't this a radioactive metal? Luo Nian was puzzled.

"Well, that's true, the two semicircles just now are plutonium-239, and the metal that encapsulates them is beryllium, which can be used to reflect the neutrons released by plutonium-239 when it undergoes a chain reaction." Chu Ru patiently explained.

"Chain reaction?" Luo Nian looked puzzled.

"Hee-hee, this is in the atomic realm, and when the radioactive metal plutonium-239 reaches a critical mass, a chain reaction can occur." Chu Ru's smile was like a flower.

"Critical mass?" Luo Nian became more and more incomprehensible.

"Yes, the critical mass of plutonium-239 is 5 kilograms, and only two pieces of plutonium-239 that are equal and reach the critical mass need to be physically contacted, which can trigger the chain reaction of plutonium-239, and the process of chain reaction will release a large number of neutrons, and when the escaping neutrons pass through the metal shell (beryllium) wrapped with plutonium-239, they will be reflected back and re-participate in the chain reaction!" Chu Ru pinched Luo Nian's face, her eyes full of love.

"That's too simple, isn't it, isn't it possible for everyone to make a nuclear explosion?" At this time, Li Di also came up to join in the fun.

"You think everyone can have plutonium-239 and beryllium? It is precisely because Liu Chao's demon genus is more special that he can do so, but his current realm is not enough to control this kind of earth-destroying power. Chu Ru said solemnly.

......

"Congratulations to the Trialist for successfully killing four teams, since your team's realm cannot be assessed, the ultimate purgatory mode has been opened for you, the difficulty of the trial has been doubled, and you only need to kill one more [Machine Spirit] to complete the first stage of the mission! This team will be teleported to the Dream Space in an hour's time! At this moment, a mechanical voice came from Luo Nian's waist again.

As the broadcast ended, a teleportation circle glowing with golden light appeared under the feet of Luo Nian and the others, and in an instant, several people disappeared in place.

In an instant, the four of them returned to the same house from which they came.

Looking at Liu Chao, who was half-lying on the ground, Luo Nian rushed over and helped him up, "Liu Chao, how are you, can you still fight." ”

"It's just a skin injury, just a little adjustment." Liu Chao said with a pale face.

"It's not okay to hold on, in my opinion, your internal organs are all shattered, and if you don't treat it in time, you will fall to the root of the disease!" Chu Ru said calmly, and took out a green medicine bottle from his waist as he spoke.

"Phantom liquid? A bottle worth 20 million magic coins can instantly restore the fatal injuries of cultivators in the Condensation Realm and below the Condensation Realm! Li Di's eyes straightened, and he kept swallowing his saliva.

"It's too wasteful, I'm not worth it!" Liu Chao kept shaking his head, you must know how many people can't earn 5 million magic coins in their lifetime, let alone 20 million magic coins worth of phantom liquid.

"It's okay, anyway, after the qualifying round, you have to join Ashwan, and you will pay me back slowly!" Chu Ru said calmly, with Liu Chao's character, he would never accept it if he gave it directly.

……

After taking the phantom liquid, Liu Chao's complexion instantly improved, but it took a few breaths to return to the same as before.

Liu Chao immediately arched his hand at Chu Ru and said, "Thank you, I will definitely repay it in the future!" ”

"Well, it's okay, just give it back to Luo Nian." Chu Ru smiled slightly, he knew that Liu Chao was not good at words, but Liu Chao's performance today really shocked her.

With the strength of the Condensation Realm, the energy of the Atomic Split Bond Realm was released, which was also equivalent to the power of the earth-level demonic beasts.

Such a method is simply a dimensionality reduction blow for cultivators of the same realm.

If the manifested plutonium-239 is huge enough, it is not impossible to destroy a medium-sized volcanic city in an instant.

"Liu Chao, can you teach me this method of rubbing nuclear bombs, in case I encounter danger one day, it can also be used for self-defense!" Li Di teased with a red face.

Hearing this, Liu Chao immediately manifested two fist-sized plutonium 239 semicircles in front of Li Di, which scared Li Di enough.

You must know that the plutonium-239 manifested by Liu Chao at this moment is more than 5 times larger than the original mass, and if there is really a nuclear reaction, Li Di may have gone to the West Heaven to see the Buddha.

"People are just talking, not that's what they mean, Liu Chao, how did you learn how to make an atomic bomb?" Li Di's voice became demonic, and he hid behind Luo Nian like a little lady, for fear that this unstable metal would have a chain reaction.

"I also tried to imitate the method of the earth's civilization, and I never thought that its power was much beyond my imagination!" Liu Chao said thoughtfully.

As he spoke, he waved his fingers forward, and in an instant, the two metal semicircles suspended in mid-air disappeared without a trace.

"What kind of creature is a machine spirit? And what is the ultimate purgatory mode? Luo Nian looked at Chu Ru on the side, his eyes full of doubts.

Chu Ru also looked at Luo Nian gently, "The machine spirit is also a kind of demonic beast, similar to the spirit on Venus, and it is good at using weapons to fight, but its strength is far from being comparable to the spirit on Venus." ”

"No, if we really have to deal with such a creature later, then we won't have a chance of winning?" Luo Nian frowned and said with sincere fear.

"It's okay, it's absolutely no problem if it's you, the machine spirit is super weak, not to mention that the realm is still suppressed in the condensation realm!" Chu Ru's smile was like a flower.

"Then I'm relieved!" Luo Nian breathed a long sigh of relief, and there was a little more confidence in his eyes.

"It's very weak, it should be as weak as 10 Tenga!" The corners of Chu Ru's mouth lifted slightly, and he said proudly.

After Chu Ru said this, the eyes of the three of them widened in an instant, and they almost said in unison, "What? Is this still weak? ”

"Well, it is indeed very weak, in this vast universe, there are many kinds of spirits, such as annihilation spirits, death spirits, soul spirits, void spirits, emperor spirits, fairy spirits, demon spirits, gods, holy spirits, evil spirits, etc., all of which are the existence of one side of the dominant party, and the machine spirit is not ranked at all." Chu Ruyan smiled, as if she was looking forward to Luo Nian's next performance.

"Okay, although I don't understand it very well, but Chu Ru said yes, then it's absolutely okay!" Luo Nian said comfortably.

After all, Chu Ru was his guide, and without Chu Ru's help, he would not have been able to come all the way so smoothly.
