"Yellow Dragon Profound Art" Fei starts chanting his cultivation art and spiritual qi from Heaven and Earth gather near him.

"Martial Spirit Swallow" He deployed his martial spirit and 2 head serpent swallowed opened their mouth and swallowed spiritual qi all around him.

"Refine! I have to succeed this time" Fei gritted his teeth, biting his lip as blood flow down.

But there was no sign of a breakthrough.

"I don't believe I can't break this rule. I don't believe I can't break this seal. I won't be confined in one corner. I will rise and rise above this Heaven. The breakthrough I can Breakthrough" Fei roared with all of his might.

His body shone again showing breakthrough signs.

"Martial Spirit at full power swallow qi for me" Fei roared and run his martial spirit at full strength.

His martial spirit two head shone in yellow and blue color, they roared loudly and sucked large and large amounts of qi in Fei body.

The amount two head of the snake was sucking was increasing at rapid speed.

Qi follows through Fei body, it was like a tsunami but larger than before, it passes through all of his cells.

His muscles, bones, veins, inner organs, the brain were getting stronger and tougher, his body was shining in golden again but this time, it was a little different.

"Crack, Crack"

At the same time, his bones were breaking as well as connecting the same for his muscles which were tearing apart and connecting.

"AHH, AHH, AHH" It was like hell, breaking such pain for the 13-year-old kid was no less than torture.

"I must hold onn. Afterr thiss I..... I ca....n..n grow stongerr" Fei voice was shuttering while saying, he couldn't even properly talk.

It already took a lot for Fei to hold on for a single moment.

His body was remodeling and slowly growing stronger and stronger.

Finally, a brilliant golden light shone in through Fei body toward the sky.

At the ground, Fei was still sitting cross-legged. His upper body was naked showing a muscular body. He wasn't like a bodybuilder with apes and biceps but his upper body was slim and perfect.

"Brizz, Brizz"

"Rumble, Rumble"

Large and Large thunder clouds start striking each other just above Fei.

The sky was getting darker with a dark cloud. A large thunder cloud was brewing above Fei.

At a high mountain inside the danger zone of Sky High Forest, one old man with a wrinkly face, white beard, and mustache, holding a stick looking at thunder cloud above Fei said " Someone is defying the rules of Heaven after all these three hundred years. Even this old man never tried to do something like this, a kid with a body refining stage did. Ah, I am seriously getting old. But cultivation is the way of defying heaven, one needs strong luck, will, and spirit to overcome every obstacle. Let's observe this kid"

At the same time while enjoying the feeling of breakthrough after 3 years.

Fei heard some noise and look up in the sky and two words came out of his mouth "Holy Cow"

Fei screamed towards the sky saying "You got be kidding me? Is this the punishment of break the rule made by Heaven?"

"First you sealed my dantian, now that I breakthrough you want to kill me? Do you think I am not ready for you? Today I will break your shitty rule" Saying all this in anger Fei took out a slender black sword

It was a single-edged sword with a bloodstain on its blade. It was like a Katana but a little heavier.

At the same time cloud over Fei was huge it was rumbling with all of its might.

It was enough for adults to get horrified over this but Fei wasn't least horrified instead he was assuming the power of thunder to be great.

"Drizz Brizz"

"Bang"

A large blue thunderbolt falls from the sky towards Fei with all of its power at extreme speed.

"Buddy It's time for you to shine," Fei said while holding a black sword in his right hand with excitement.

"I'm off," Fei said and run away from thunderbolt but was he really running away?

No! After reaching a certain distance he stopped and looks back towards the thunderbolt.

"Brizz Drizz"

Small thunders cover his leg and he moved.

"Lightning leg"

His speed was 3 times faster than before. He was moving at extreme speed. This is Crazy Lightning Run movement art from his arsenal.

Before he could reach the place where the lighting fell. Lightning was already there instead it was moving towards Fei in the horizontal ground.

Both had fast speed but next when they were about to collide against his sword move.

With a complete turn above his head, Fei was initialing his next move. His sword swing from right to left then left to right.

He jumped a little and rotates his body at extreme speed moving towards lighting.

Fei sword tip was at the front when he shouted "Overlord Dragon Sword Art First Style- Hidden Dragon Claw Collides"

A flash of the yellow dragon was at the tip of his sword. The yellow dragon slowly takes out its claw toward the thunderbolt trying to strike it down.

"Boom"

"Boom"

Dragon claw and thunderbolt collide with powerful force.

"Cough" Fei fall a little far away and coughed blood.

Although he successfully counters the first thunderbolt, he was also very much injured. His same new clothes were torn apart and there were bruises and wound all over his body.

Fei didn't waste time and took out a pill from his spatial ring.

This was a body recovering pill of a profound rank higher tier.

He swallowed the pill and sitting with crossed legs start healing his injures. Except for martial arts, there are other professions in this world like Alchemy, Weapon refiner, Assassin, etc.

Creating a pill is the job of an Alchemist. These people have much more reputation because the pill is great to help cultivators.

The spatial ring that Fei was is made out of space stone where are rare materials found from different mines.

So normal cultivator cannot hold a spatial ring only renowned family members can hold it.

Fei was still recovering hard to fight against the second thunderbolt that was brewing in the sky.

But the thunderbolt itself didn't give enough time for Fei to recover.

The second thunderbolt was even fierce than the previous one, it was taking the shape of a sword made out of thunder.

"Rumble"

Unlike the previous one, it came down at an extremely fast speed enough to split the earth.

Fei wasn't totally recovered; still, he got up and holds his blade on his right out.

Fei took a light jump, start rotating at a fast speed with his sword in his hand.

He stops rotating and makes five small movements in the air, with summersault holding a sword with both of his hands near the thunderbolt.

He slashes his sword with both of his hands, screaming "Overlord Dragon Sword Art Second Style- Dragon Tail flings"

Within his sword a large dragon tail phantom raises up with all of its might, it collides with the thunder sword.

"Screech Bang"

"Boom, Boom"

But this time sword was more powerful than the previous, Fei didn't hold back anything thing when his sword attack was nullified he took back his sword and create ten palms in the air then the number of palms increases with Fei next move.

"Golden Ape Fist- Ten Hands Strike"

"Golden Ape Fist- Hundred Hands Strike"

"Golden Ape Fist- Thousand Hands Strike"

The last attack with a thousand palms created with qi was colliding against the thunder sword and it finally nullified that sword.

Fei landed on land and start recovering his qi when he saw the next thundercloud brewing above.

In this attack half of the qi stored in his body was used up. Unlike the dantian, the body can't hold a large amount of qi so Fei needs to replenish it again.

He sat on his knees took out a pill and put it in his mouth. After swallowing a pill large tsunami of spiritual qi was recovering in his body.

This was Qi recovering pill which helps in recovering qi in his body.

But this time some strange phenomenon happens in the sky which almost rips apart much another thunder cloud.

It was a black thunder and it happens to be crazy strong that it cut and eat other thunder clouds.

The worst thing is that this black thunder was coming towards Fei at extreme speed almost like a flash.

Fei was also shocked because of this but he didn't hesitate and took out his sword from the spatial ring.

Fei didn't make any movement or showed any art instead waited for black thunder.

When black thunder was near Fei, he broke out a very powerful aura around him.

"Overlord Dragon Sword Art Last Strike- Ferocious Dragon Hunts"

A large dragon broke out of the sword, trying to eat black thunder with his sword.

It was amazing power but in front of black thunder, it was nothing.

Black thunder broke out his attack then his sword in half then went inside his body.

It travels through his body breaks his veins, bones, and inner organs finally next to his dantian near the stomach.

Black thunder roared and attacks his dantian trying to destroy it but at the same time, something unexpected happens.

All of its energy was sucked out by a seal and his soul more like something that is residing in his soul.

At the same time, the thunderbolt around Fei shook, the sea around the land erupted like a tsunami.
