Yan Yu's first day was spent under the thunder and lightning, his body was charred and tattered, and a large amount of thunder and lightning was left in his body.

Thunder brought him back to the Yan Palace, let Yan heal him, looking at the seriously injured Yan Yu, Yan had some feelings in his heart, and used his spiritual power to heal Yan Yu, and soon Yan Yu's wounds healed, but those thunderbolts were still in his body.

"Xiao Yan, don't worry. Lei Ting looked at Yan and knew that he was worried about Yan Yu, but if he wanted to become stronger, this was something he had to go through.

After resting for a few days, Yan Yu completely recovered, and came to the Thunder King Palace again, this time there was no thunder and lightning, because the thunder was going to carry out a new cultivation, and the thunder and lightning had to come at intervals.

When Yan Yu came here, there was still electricity left on the grass, especially the red area, because that was where Yan Yu bled and where the lightning was strongest.

"Yan Yu, do you see those boulders? Different sizes of stones have different weights, the smallest of them is five thousand catties, what you have to do is to rely only on the strength of your body, in a month, lift the largest piece. Thunder said, pointing to the boulder not far away, growing larger and larger, almost approaching a hill.

"The smallest and lightest are 5,000 catties! It's not a joke! Let me break through the heaviest one in a month, it's impossible!" Yan Yu was shocked and said loudly, completely denying himself.

"Don't worry, during this month, I will give you a baptism of thunder and lightning, okay, go ahead!" said Thunder, kicking Yan Yu to the side of the five thousand boulders.

If you don't lift it well, I'm afraid you'll be crushed to death, he thinks. Yan Yu looked at the 5,000-pound boulder carefully, and found that it was very smooth, without any bulges or depressions, that is to say, Yan Yu did not have any starting point, he could only rely on his strength to hold the boulder tightly, and then lift it.

"Ah......h

Yan Yu shouted, one hand against the ground of the boulder, the other hand dragged the stone body, the stone was too big, Yan Yu was like an ant to shake an impossible thing.

However, the result was beyond his expectations, he lifted the boulder of five thousand catties at once, and he could lift it with one hand, he felt as easy as he usually took a small stone, Yan Yu threw it hard, and threw the stone a hundred meters away, which surprised him.

"Yan Yu, don't deny yourself, firmly believe in yourself, break through one by one, and the next one is eight thousand catties. Thunder said, pointing to another.

This stone is not smooth at all, it is all holes, Yan Yu thought to himself, as long as he has a hand point, he can generally lift it with force.

I saw that Yan Yu was ready, the boulder of eight thousand catties, Yan Yu easily lifted it, suddenly, Yan Yu felt that the stone in his hand had become heavier, he was puzzled, his hands became more and more difficult, and the stone was also crooked, falling from time to time, smashing a big hole on the ground.

"Yan Yu, hold this stone for me all day today!" Hearing Lei Ting's words, Yan Yu did not complain, because he had a goal, that is, to go back, his family and friends were waiting for him.

Yan Yu was holding an 8,000-pound boulder, the boulder blocked the sunlight, making him feel like he was in the dark, and when he lifted it, Yan Yu didn't know how many times it fell, but he lifted it again one by one.

After three days, Yan Yu could already lift it easily, because he was used to the weight.

On this day, Yan Yu didn't need to lift the stone, because this day was the time for the thunder and lightning to forge the body, and the thunder turned into a thunder dragon, roaring towards the sky, and the brilliant sunlight was obscured by dark clouds at this time.

The blue lightning slashed, emitting amazing spiritual power fluctuations, and Yan Yu felt that this thunder and lightning was stronger than before.

With the first split, Yan Yu's clothes were burned, his flesh turned red, and the thunder and lightning in Yan Yu's body began to rage, piercing Yan Yu's body, revealing white bones.

"Ah......h

Yan Yu roared, this was more painful than anything else, the lightning in the sky fell, and the lightning that flowed in Yan Yu replaced the original lightning, Yan Yu endured, and the green grass was dyed red again.

With the thunder in the sky, Yan Yu no longer had complete skin on his body, there was charcoal everywhere, black smoke was emitting, and his bones couldn't bear the cracks.

In this way, Yan Yu survived another day, when the thunder was brought back to the Yan Palace, Yan Yu had all turned into charcoal, with the help of Yan's spiritual power, the charcoal shattered, revealing new skin, where the halo flowed, the cracks in the bones had begun to repair themselves, Yan Yu looked at his new body, and felt full of life.

After resting for one night, Yan Yu arrived at the Thunder King Palace very early the next day, looking at the eight-thousand-pound boulder, Yan Yu raised his leg and swept it, and kicked the boulder into the distance.

Time flies, in a month, Yan Yu was scorched by the thunder and lightning many times, and his physical body was reborn many times, and now Yan Yu wants to break through the last boulder, according to Thunder, it weighs 100,000 catties.

Looking at the mountain in front of him, Yan Yu took a deep breath, closed his eyes to recuperate, and then quickly rushed up, grabbing the mountain directly with both hands.

"Yikes!"

Yan Yu howled, but no matter how hard he tried, the mountain never moved, not even shaking to be exact.

Yan Yu was puzzled, in the past month, he could easily lift tens of thousands of catties of stones, but this one couldn't even shake it.

"This thing is suppressed under this mountain, and this thing has a strong attraction that sucks the whole mountain, so if you want to lift him, you have to break through 100,000 catties. Thunder told the reason, and at the same time he told Yan Yu that he could rest for a day today, and tomorrow would be the last baptism of thunder and lightning.

Yan Yu returned to the Yan Palace, and when he had nothing to do, he pondered alchemy there, and suddenly, he had a problem and ran straight towards the Smelting Palace.

"Master, I have a question for you. ”

"Say, what's the problem?"

"Can two magic diamonds be mixed and refined during the alchemy process, that is, one sword and two spirits later?"

Yan Yu asked, this was what he had in mind, if it could be used, alchemy would be greatly changed.

"It is recorded in the scriptures that there was a precedent that the end result was that the sword was broken and scattered, because they could not live together and share the same sword. Smelting Gold replied, and let Yan Yu go back, and told him not to try, because it was not only the sword spirit that was harmed, but also himself.

Yan Yu firmly remembered, is it really not possible? Yan Yu wondered in his heart, the failure of the ancestors does not mean that the descendants cannot surpass, Yan Yu feels that he must try, but not now.

The next day, Yan Yu came to the Thunder King's Palace, today will be the last time he will be baptized, and no matter how much he cultivates after that, his physical body will not be able to improve.

On this day, the thunder took him to a new place, where it was extremely dark, and the roaring thunder was unusually bright.

"This is the Valley of the Thunderbolt, the place of your final trial, and you can pass it by reaching the depths of the Valley of Thunder and returning. Thunder said, and let Yan Yu move forward.

Yan Yu can now resist strong thunder and lightning, and the thunder and lightning in the Angry Thunder Valley are different, they are very strong, every thunder dragon of the thunder dragon clan will come here to train, only through here, they can be called a thunder dragon.

Yan Yu is on the road, this time I don't know how long I will stay, Thunder is watching Yan Yu at the mouth of the valley, the purpose is to protect him, after all, the angry thunder is too powerful.

By Lei Ting's side, a figure flashed, white clothes, long black hair, he was Yan, come to see Yan Yu.

In the Valley of Angry Thunder, the trees are all scorched black, and the creatures that can grow here are all carrying lightning, Yan Yu walks through the darkness, and encounters some small thunder beasts from time to time, and the surrounding thunder and lightning are all angry thunder, even if it is a small thunder beast, Yan Yu does not dare to provoke.

He continued to move forward, he was a little puzzled, the thunder and lightning in the sky did not hit him at once, and it was not very easy to reach the depths of the Thunder Valley and return, but Yan Yu knew that it would never be so simple, and he moved forward carefully.

Roar!

On the way, Yan Yu encountered many thunder beasts, but Yan Yu just avoided them and slowly advanced towards the depths of the Thunder Valley, he didn't want to provoke, otherwise the consequences would be unimaginable.

Yan Yu had already come to the depths of the Thunder Valley, as long as he walked a few more steps and returned, however, at this time, a thunderbolt from the sky struck down, startling Yan Yu.

"Didn't split!" Yan Yu was relieved and didn't split him.

Roar!

"It seems that he has woken up, the valley lord of the Furious Thunder Valley, the Raging Thunder Beast. Outside the valley, Thunder said.

There was a loud bang, shaking the heavens and the earth, endless thunder and lightning fell, smashing the ground, Yan Yu wanted to go back quickly, however, the exit was blocked by a behemoth.

Its lightning eyes flickered in the darkness, its claws were covered with thunder and lightning, its black hair stood on end, and the tips of its hair shone with lightning.

Roar!

It roared, attracting angry thunder from the sky, slashing at the body to make the thunder and lightning stronger, it quickly rushed towards Yan Yu, slapped its claws, Yan Yu dodged, however, when the claws landed, the lightning spread around, Yan Yu was hit, and he was a little paralyzed.

The fire spirit emblem shone, the red flames burned his arms, Yan Yu acted quickly, but his speed was not as fast as lightning, the angry thunder beast swung and hit Yan Yu on the valley wall, and the angry thunder in the sky slashed down, and it was full of lightning again.

"Poof"

Yan Yu vomited blood, he couldn't use his inner spiritual power, because his spiritual source was all shattered, he quickly dodged, looking for a place with many obstacles, here, the Angry Thunder Beast couldn't move smoothly.

Yan Yu swung his fist and hit the door of the Angry Thunder Beast, it roared, and Yan Yu was also hit by the lightning on its body and rebounded, the Angry Thunder Beast opened its mouth, its two sharp and long teeth were exposed, and the thunder and lightning condensed in its mouth.

Bang!

With a loud bang, the attack hit the ground, and the pulsing attack spread out on the ground, destroying all obstacles, and Yan Yu jumped to the ground, dodging the attack.

"What should I do?" Yan Yu had no solution, no matter what, he would be struck by lightning, escape, impossible, his speed was not as fast as it.

The Raging Thundermon leaves a shadow of lightning in the darkness and travels quickly, he can replenish the lightning because this is the place where the lightning gathers.

Cracks had already appeared on Yan Yu's body, dripping with blood, and on the red blood, lightning flashed.

Yan Yu pointed like a sword, gathering the thunder and lightning left by the thunder in his body and turning it into a thunder sword, Yan Yu waved the sword body and rushed towards the angry thunder beast.

The angry thunder beast swung its claws and knocked Yan Yu into the air, Yan Yu used the flames, quickly sprayed and fell, sitting on the back of the angry thunder beast, the pain of the lightning strike penetrated the heart, Yan Yu raised his sword, and inserted it into its back, and suddenly the blood of the angry thunder beast gushed out, Yan Yu drank a lot with his mouth open, and the blood on his body was all over his body, and the wound also seeped a lot of blood.

The Angry Thunder Beast trembled, Yan Yu fell, and the Angry Thunder was wrapped around his body, he struggled, and the blood of the Angry Thunder Beast that he drank flowed in Yan Yu's body, and the thunder and lightning drilled into Yan Yu's body.

Roar!

The Furious Thunder Beast roared, knocking Yan Yu into the air, and the condensed thunder and lightning blasted out like a cannonball, and at this time, the angry thunder in the sky just fell, and Yan Yu was hit on both sides.

However, the thunder in the sky was like a river, attracted by Yan Yu, and the attack of the angry thunder beast gradually shrunk, absorbed by Yan Yu, Yan Yu was wrapped in angry thunder, and his eyes were glowing with blue light, revealing thunder.

"Ahh

Yan Yu roared, the thunder and lightning on his body condensed, attacking the Angry Thunder Beast, with a loud bang, there were flying stones everywhere, and cracks appeared in the mountain.

Yan Yu fell, looking at his body, suddenly, a lightning bolt fell from the sky, Yan Yu dodged, but found that the thunder and lightning locked him, Yan Yu bent his elbow to resist, and soon he found that he didn't have anything at all, but felt that he had enough strength.

The Raging Thunder Beast gave up attacking Yan Yu, and Yan Yu returned to Taniguchi smoothly.

"Master, why was I struck by the thunderbolt, but instead of being injured, I felt that I had enough strength?" asked Yan Yu.

"You drank the blood of the Raging Thunder Beast, and now you, like him, belong to the Raging Thunder physique, and can absorb lightning to replenish spiritual power. Lei Ting said with a smile, this was unexpected, and he didn't expect Yan Yu to get this.

The three of them returned to the Thunder King's Palace, and Thunder wanted to test Yan Yu's Angry Thunder Physique.

"Yan Yu, fight me. Thunder said.

Yan Yu knew, and quickly impacted, and the flame fist hit the thunder, which was mixed with thunder and lightning, and with a bang, the thunder retreated.

"The strength is good, the speed is too slow!"

"Thunder Cannon"

The thunder roared, and a huge artillery bombardment bombarded Yan Yu, however, it was useless, the spiritual power of the thunder and lightning was absorbed by Yan Yu and became Yan Yu's spiritual power.

The battle was over, and Thunder came to the result, Yan Yu was already a person with an angry thunder physique, as long as he wanted to absorb it, any thunder and lightning attack would be absorbed by him.

Coming back to the last mountain, the black mountain has no trees, Yan Yu walked into him, quickly lifted it, and when he was in the air, Yan Yu saw the thunder and lightning between the earth and the mountain.

The thunder and lightning left Yan Yu's body absorbed, and Yan Yu quickly and easily lifted the mountain of 100,000 catties.

Yan Yu took out the thing under the mountain, but he didn't expect it to be a pair of bracers, and there was a blue gem on the bracers, flashing with thunder and lightning.

"Yan Yu, this is my gift to you, he can you use the thunder and lightning spiritual power in your body. Thunder said.

"Master Xie!" Yan Yu was so happy, he didn't have a spiritual source now, and this bracer would be a big weapon for him.

It's been two years since he came to the Dragon Spirit Domain, Yan Yu really wanted to go back, but the time hadn't come, a white dragon flew in the sky, and his white body was very beautiful, he was Yan Yu's third dragon master, Heavenly Dragon Emperor Tianxin.
