On the top of the mountain.

Yao Lao returned to Xiao Yu's side with great speed.

Looking at the piece of coke on the ground, he couldn't help but feel a little worried, this experiment itself was extremely dangerous in his opinion, although Xiao Yu said that it would definitely succeed, he also knew that it was just to reassure him.

Just now, he didn't hesitate to spend a lot of soul power to recover, just to help Xiao Yu cushion the thunder more.

But fortunately, it was mainly the three beast fires that suffered the power of the heavenly thunder, and Xiao Yu himself only endured a little residual power.

Right now, those three beast fires have been tempered.

This newly born blue-purple flame was the product of the three beast fires that merged into one under the tempering of the heavenly thunder.

......

"There is still a trace of qi left, and then it depends on your own creation."

Yao Lao waved his sleeves and returned to the ring.

With the disappearance of Yao Lao's soul body, the thunderclouds in the sky have also disappeared.

The sun is shining back on this small valley.

Click-

The pitch-black humanoid coke cracked.

A crack emerges, and then the crack becomes denser and denser.

The blue-purple flame above the black charcoal floated up and down.

Originally, the three kinds of beast fire were tempered by the heavenly thunder into this only fusion beast fire.

The last vestiges of the three magical beasts had also dissipated.

Now this fusion beast fire, Xiao Yu has been able to control it perfectly.

Of course, the premise is that Xiao Yu can wake up.

......

Minutes and seconds passed.

Xiao Yu's aura is getting weaker and weaker, and it is even no different from a dead person.

However, just when the aura on his body reached the bottom.

Suddenly, a powerful aura erupted from him.

Immediately afterward, the blue-purple beast fire also instantly integrated into his body.

Boom ——!

Black debris was scattered all over the place.

The black shell of Xiao Yu's body, which was perfectly stated, was shattered.

And his eyes opened at this time.

"It worked, I made it!"

Unable to suppress the ecstasy in his heart, Xiao Yu shouted wildly in the depths of this Demon Beast Mountain Range.

His voice echoed through the valley.

Yao Lao's figure also appeared at this moment, looking at Xiao Yu with gratifying eyes.

......

"Here, put on your clothes first."

Yao Lao handed over a black cloth robe, as well as an elixir to restore his injuries.

Xiao Yu noticed that he didn't have any clothes on him just now.

He smiled and took the clothes handed by Yao Lao.

"Teacher, I succeeded!"

Yao Lao stroked his beard and nodded slightly.

The blue-purple flame just now should be the fusion beast fire formed by the three beast fires that have been tempered by the heavenly thunder.

It's just that this kind of operation has no precedent, and it should never come again.

Except for Xiao Yu, no one knew what level of power this fusion beast fire could reach.

......

After putting on his clothes and swallowing the elixir, Xiao Yu checked his state.

The heavenly thunder just now not only tempered the beast fire.

There was also aftermath that fell on him.

And since ancient times, there has been a saying that thunder can quench the body.

At this time, it has undergone a real baptism of "heavenly thunder".

Although Xiao Yu suffered serious internal injuries in his body, he was also blessed by misfortune.

Nourished by the medicinal power, his body quickly recovered as before.

Not only that, if you talk about physical strength alone, he even feels like he can beat the two of his previous self!

In other words, at this time, Xiao Yu's physical strength has more than doubled under the tempering of the heavenly thunder!

And after his meticulous observation.

Heavenly Thunder not only temporarily tempered his body, but also stimulated the potential of his physical body.

If he has a suitable thunder-attribute fighting skill in the future, he will also get twice the result with half the effort when he cultivates.

......

"You kid, it's still very useful to temper your body day and night!"

Yao Lao couldn't help but sigh that Xiao Yu had too many ideas.

Fortunately, even after he was promoted to Dou Ling, he was constantly cultivating his physical body.

It turned out that it wasn't just to enhance that bit of power.

More to wait for today!

"Teacher, can you help me take a look at the beast fire after the fusion!"

Xiao Yu raised his hand slightly, and the blue-purple flame just now resurfaced.

Yao Lao looked at the fused beast fire with a little surprise.

Because on this beast fire, he didn't even feel the slightest manic aura!

......

Generally speaking, although almost all fighters with fire attribute fighting energy will want to be able to have a special kind of flame.

But there are very few people who really control the beast fire.

And most of them are alchemists.

Actually, the reason is very simple.

There will be a trace of the residual spiritual wisdom of the monster in the beast fire.

Once you use the beast fire, that residual spiritual wisdom may disgust you.

The soul power of the alchemist is stronger than that of ordinary fighters.

That's why they're able to resist this interference and make better use of the beast fire.

There have also been people who have tried to directly erase the remnant soul of the demonic beast in the beast fire with powerful soul power.

But after erasing, the beast fire dissipated directly.

Therefore, that trace of spiritual wisdom is like the core of the beast fire, which can only be suppressed, not eliminated.

......

"It stands to reason that the beast fire will have irritable fluctuations because of the interference of the demonic beast's intelligence."

"Strange, why don't you have any of them in this fusion beast fire?"

Xiao Yu smiled slightly, the wisps of blue-purple flames lingering around his fingertips, very docile.

Just the moment he woke up.

He had only just learned the reason for this flame entering his body.

"Teacher, the soul aura of those three beast fires seems to have been wiped out by the heavenly thunder, and only a trace of uncivilized spiritual wisdom remains."

As he spoke, Xiao Yu also began to sit cross-legged on the ground and began to feel this magical fusion beast fire.

At the same time, he urged the incineration technique to start refining.

Yao Lao stayed aside and acted as a protector for Xiao Yu.

......

However, this time, because the fusion beast fire was unusually docile, and the previous three beast fires were all tamed by Xiao Yu.

In less than a quarter of an hour, Xiao Yu completed the refining.

A powerful aura burst out from Xiao Yu's body.

The fighting energy in the body could not be suppressed and began to flow in the meridians.

"Ah——!h

With a roar, the clouds in the entire sky seemed to be streaked by a shock wave.

A blue-purple flame ignited on Xiao Yu's right hand.

Immediately after that, a punch was blasted out, and the small mountain and stone wall in front of him were instantly penetrated by this terrifying power!

The entire mountain wall became scorched, and the flames erupted so fast that even the eye could not keep up!

Swift as thunder!

"The power of this fusion beast fire is comparable to the origin beast fire of a fifth-order demonic beast!"

Yao Lao looked at the scene in front of him in disbelief.

What's even more exaggerated is that Xiao Yu is now able to control this beast fire freely.

In a way, it was more suitable for him than the fifth-order beast fire!

......
