"As you wish."

At the moment when Nie Li's words just fell.

'It's this speed again! ’

The rock dragon's eyes shook violently.

Then an unstoppable force suddenly came.

Just like a volcanic eruption or an earthquake, and as violent and incomparable as a snow-capped mountain collapse and countless tons of TNT exploding, Nie Li pressed Yan Long's broad chest with the kinetic energy falling from the sky from high in the sky and the speed of 90 times the speed of sound!

A ring-shaped shockwave of terror was created!

All the concrete structures in the range were torn apart in an instant like papier-mâché, and the violent air waves carried the countless rubble, debris, and smoke and dust to spread and rise in all directions, like gray waves sweeping up.

The sky is falling, the sun and the moon are gone!

The shock wave made everything within a five-kilometer radius feel as if it had been plowed by 15,000 tons of conventional missiles.

This is the power of Superman after his real outburst!

Click!

When Nie Li's palm fell, the rock dragon's eyes suddenly bulged, first the dark red spiritual power field was shattered in an instant, and then the rock muscles on his chest instantly cracked countless fine lines, and the whole person was directly shot away countless meters away, and the person was still in mid-air, and the dark yellow blood was sprinkled outward like no money.

The rock dragon, who had never felt pain since awakening, felt it for the first time.

Pain, pain, pain!

There was pain all over my body, as if I had been hit by a train.

But the blow, although severe, did not kill him.

After all, for a B-level powerhouse in Stage 4, as long as it is not a key part such as the skull and heart, it can be recovered, but the speed of recovery is fast and slow.

"If you have the ability, one more punch,"

In the ruins, the rock dragon got up again, and opened his mouth with a loud urn.

As he got up, the whole person swelled, became taller, and bigger again, and finally turned into a meteorite giant close to 5 meters!

This is the complete body of his spiritual energy that bursts out with all his might!

Defense and power are increased by one notch, but the speed is reduced.

However, at this time, it is very suitable to deal with a person with a high explosion like Nie Li.

Yan Long originally thought that although he couldn't keep up with the speed of the other party, the instinct formed by the long-term battle should be able to react, but he didn't expect that it was still not enough.

As long as the defense can hold up, my injuries will gradually recover. ’

No one likes to stand and be beaten, but he has no better way, so he has to do this.

This is also something that can't be helped, the other party is not only physically strong, but also hangs him in all aspects of speed and strength, and he can't fight at all, so he can only rely on defense to carry it.

If Neve and Instantaneous Light hadn't died, they could have tried to besiege and kill Nie Li, but there was no if, so they could only be blamed for being too light on the enemy.

I never imagined that such a perverted character would exist, and I didn't need psionic energy to be so strong.

However, what makes Yan Long a little fortunate is that there is no shortage of spiritual energy after the B-level second order, as long as the opponent can't break the defense, he can carry it until the other party gives up.

"Huh."

Nie Li didn't expect that under the explosion of his full strength, the person in front of him was actually only injured, and he was suddenly a little surprised.

Moreover, he noticed that after the rock dragon recovered quickly, his aura became stronger again, and his size became even larger.

'What's the matter, what does this old boy mean standing still, waiting for me to make a move?' ’

Nie Li originally thought that the other party was going to put some big move, and he was suspended in the air and waited for a few seconds, but found that the rock dragon just put on a fighting posture and did not make any other movements.

"Why, are you going to let me strike first, or do you think I can't break the defense, so I just mess up and don't attack when I get beaten."

Unexpectedly, Nie Li actually guessed his thoughts, if Yan Long's rocky old face could change color at this time, it would also turn red.

"I have to say, you are really naïve."

Swish!

When Nie Li finished saying this, he quickly came to the vicinity of the rock dragon, and then the heat ray erupted again!

Multiply!

Maybe it was because Nie Li's heat rays had not yet risen to the level of a silver superman, but at this time, the ultra-high temperature could not melt the hard meteorite, but only burned the entire body of the rock dragon red, and the temperature also increased wildly.

But after the change in the molecular structure of the body, the rock dragon no longer has much feeling about the ultra-high temperature, just a little hot.

Seeing that Nie Li's heat ray didn't seem to be able to do anything about him, Yan Long finally breathed a sigh of relief in his heart.

Thinking of the grievances of this battle and the dead teammates, he couldn't hold back any longer, and opened his mouth to sneer:

"Is the donkey skill exhausted, and this is the heat ray of Superman? It's just heating me up. ”

Although he couldn't beat Nie Li, if he could make him uncomfortable through words, Yanlong also felt a little more comfortable in his heart.

Who knew that Nie Li was not angry, he just chuckled, and then said to him with a little deep meaning while continuing to release heat rays:

"Have you ever heard of thermal expansion and contraction?"

Hearing this, Yan Long instinctively felt a little bad, but he didn't know what was wrong:

"Huh? What the heck? ”

Because he had read so little that he didn't know what it meant.

However, even if he could sense that something was wrong, he couldn't resist it, because Nie Li's speed was much faster than his form.

If he returned to the first lithified form, Nie Li would dare to put him down first, and the outcome would be the same.

As the heat rays continued to heat, the entire meteorite body of the rock dragon completely turned red, like a red-hot soldering iron.

Seeing that the time was almost there, Nie Li immediately stopped releasing his heat gaze, and then quickly spat out a frozen breath towards the rock dragon.

Call~

The cold wind as cold as the invincible abyss instantly covered the body of the rock dragon, and a layer of frost began to form on the surface of the body.

'What is he trying to do?' If the high temperature is useless, change it to a low temperature? What's the point. ’

The rock dragon was a little incomprehensible.

But the next moment, his huge meteorite body began to change drastically.

The already extremely tall body began to expand irregularly again at this time, but this time the expansion was not controlled by the rock dragon.

Thermal expansion and contraction refers to the property that an object expands when it is heated and shrinks when it is cold.

And Nie Li took advantage of this characteristic.

"Ahhh

Alternating between cold and heat, the rock dragon roared in pain, only to feel that he was swollen from the inside out, a pain far greater than any time he had ever had.

But in just a few seconds, he wouldn't have to be tortured like this.

Rumble!!

After a loud roar, the huge body of the rock dragon, which was nearly 5 meters tall, suddenly exploded!

Thermal expansion and cold contraction are generally the internal expansion of the object, and the violent expansion of the outside leads to violent separation from the interior and explosion, but the meteorite body of the rock dragon obviously has various characteristics far beyond all kinds of stones in nature, and ordinary thermal expansion and cold contraction naturally do not work.

So Nie Li used the heat rays to burn it to the hottest and then quickly lowered the temperature, which exacerbated this change, and now the outside contracted violently, and the inside was still expanding, and the body of the rock dragon could not resist such a rapid change.

No matter what kind of substance in nature, it has its own expansion coefficient, a low one such as an ordinary rock can be exploded by simply heating it at high temperatures, and a high one such as jade can only crack it when heated at high temperatures.

Although the expansion coefficient of meteorites is very high, they also begin to become extremely unstable under the stimulation of the principle of thermal expansion and cold contraction.

The stimulation of sudden heat and cold causes the interior of the rock dragon to become extremely unstable, so it will explode.

If the rock dragon can make its body molecules almost relatively static like vibranium, then the natural thermal expansion and cold contraction will not work.

Unfortunately, he couldn't.
