The spacious room, with the flickering of flames, flickered and flickered.

The ancient shape, the golden furnace of creation, is emitting white smoke. Among them, there is a hint of fragrant smell, which makes people can't help but be intoxicated. Emperor Yu put his hands behind his back, and there was a hint of nervousness in his expression, staring at the Dan furnace with his eyes. After a moment, his pupils contracted suddenly, but he couldn't help but sigh.

Boom!

Almost as soon as the Yuhuang Emperor sighed, there was a slight sound in the Dan furnace.

Suddenly.

A pungent burnt smell spread throughout the house.

"How many times have I told you to master the flames...... You are alchemy, not murder. Emperor Yu exclaimed angrily.

"Mistake!"

Chen Han smiled secretly and opened the lid of the stove.

Sweeping out the waste that had been completely burned into charcoal, replacing it with new herbs, and sitting cross-legged again.

Looking at the Yu Emperor, who hated iron but not steel, Chen Han flicked his right finger, and immediately a cluster of green flames shot out and flew down on the Dan furnace. Putting his hands on the surface of the furnace of creation, he smiled and said, "Old man, you know that too...... This green flame is a four-grade Dan fire, and it is difficult to control itself. I have absorbed the flames of the entire Green Flame Mountain, and the power of this Green Flame is naturally dozens of times stronger than before...... So it's normal to make mistakes, but this time I've got the hang of it!"

Spread your right hand out.

Chen Han immediately surged the true yuan in his body.

At the same time, the five fingers of the left hand are slightly bent and retracted. Quickly sucked out the Dan Qi mixed with the True Yuan and poured into the body.

"Well, it's not bad!"

See this scene.

Emperor Yu nodded repeatedly.

Chen Han has mastered the process of refining his body with Dan......

Half an hour later.

Chen Han exhaled a breath of turbid air and slowly withdrew his hands.

The 'Overlord Pill' has been refined.

With a wave of his right hand.

The tooth-shaped boulder flew out instantly.

With his hands behind his back, Chen Han looked around the tooth-shaped boulder. After a while, there was a thought in my heart. "This tooth-shaped boulder is the tooth lost by the old dragon, I don't need to modify it more, I just need to remove the impurities in the boulder......

Come to think of it.

Both hands immediately waved, and a violent aura poured out wildly, and a large area of green flame quickly wrapped the tooth-shaped boulder.

Rumble!

The whole house was filled with this hot breath.

Sneer......

Green flame is strongly corrosive and plays a role quickly.

The stone shell on the surface of the tooth-shaped boulder quickly peeled off, revealing the inner layer of dragon teeth!

"Boy, be careful......"

See this scene.

The Emperor Yu on the side hurriedly reminded him.

"Roar!"

The dragon's fangs, which were placed on the ground, shook violently. A golden dragon body flew out with a bang. It looks like an old dragon. The moment it appeared, in an instant, a huge coercion swept the entire house. I saw that the golden dragon's big mouth opened violently, and it let out a roar, and it was actually crazy, wanting to swallow Chen Han in one bite!

"It's ...... Dragon Soul!"

Seeing the golden dragon body, Chen Han was not surprised or overjoyed.

Originally.

When the Celestial Dragon Sword was being refined in the underground volcano, the old man grabbed the fire dragon and blasted it into the blade. However, those fire dragons were not real dragons after all, and the difference in strength was 108,000 miles. But Rao is like this, the Heavenly Dragon Sword has also been refined into a mortal-level weapon. If you can capture this golden dragon soul, this dragon tooth will inevitably become a heaven-level weapon!

"Roaring ......"

It's just that.

This dragon soul is extremely powerful.

Although it is only a trace of the soul left on the teeth of the old dragon, the strength is also staggering. I saw the dragon soul's body circling and rushing wildly. The long body delicately wrapped around Chen Han's body. The huge dragon kiss opened violently and bit wildly.

"Trap me!"

Chen Han roared.

His right hand stretched out suddenly, and he grabbed the neck of the dragon soul, and at the same time, the green flame also spread out from his palm frantically.

"Roar!"

Huge dragon moans rang out continuously. It reverberates incessantly.

Chen Han's eyes flashed with a sharp light.

The five fingers are clasped tightly, and they are suddenly tightened.

At this moment.

The dragon soul actually danced involuntarily......

"Let me in!"

There was a loud roar.

Chen Han grabbed the dragon soul and with a furious loud noise, the dragon soul was frantically blasted into the dragon's teeth!

Boom! Boom!

Roar! Roar!

A burst of unwilling roars came out of the dragon's teeth, and the dragon soul frantically hit the dragon's teeth, as if to break free from the shackles of the dragon's teeth and impact out again!

There was a burst of golden light on the dragon's teeth.

At this moment, it shook involuntarily.

"Click!"

There was a crisp sound, also at the same time, from the dragon's teeth. On the sturdy dragon teeth, there were mottled cracks!

"Boy, use the green flame to quench the dragon's teeth. If the dragon soul escapes, this dragon tooth will be completely destroyed!" "Quick, quick!"

"Old thing, I know!"

Hands poked out.

The green flames gushed out wildly, instantly enveloping the dragon's teeth.

"Roar!"

Feel the power of incineration.

The dragon soul kept struggling...... Gradually, its struggle became weaker and weaker, until in the end, it turned into a coiled dragon pattern, deeply engraved on the surface of the dragon's teeth.

But.

Chen Han still didn't stop.

Because refining has just begun.

The green flame continued to scorch, removing the impurities in the dragon's teeth to the slightest bit. Gradually, the shape of the dragon's tooth was gradually carved out, and a black giant knife that was a man tall and extremely large appeared in Chen Han's field of vision. The giant knife had no blade and looked like a rough stone.

But.

On the surface of the giant knife, there is a golden coiling dragon carving, faintly emerging.

"Heavy knives have no edges, and great ingenuity is clumsy!"

Pluck a single hair and blow lightly at the blade. Immediately, the hair involuntarily broke in two.

Seeing this scene, Emperor Yu also nodded again and again, and praised: "Blowing hair and breaking hair...... Boy, let's quickly drip blood and confess the Lord. Judging from my experience, this is a mid-grade weapon of the Heavenly Rank. If you can take it, hehe...... Under the Martial King, there is no rival!"

Heavenly Rank Medium Grade!

Hearing Emperor Yu's judgment, Chen Han was also secretly happy in his heart.

Nodding his head again and again.

Immediately bite your finger and flick it gently.

A drop of essence blood flew out and splashed on the knife.

A strange scene appeared.

The essence blood that should have been sucked into the blade of the knife was actually like a powerful countershock at this moment—that drop of essence blood was violently ejected back, and a huge force was attached to the essence blood. A crystal clear round blood bead was formed, almost brushing against Chen Han's face.

Rumble!

The blood beads continued unabated, and they directly pierced the wall behind Chen Han, leaving a huge hole.

"I didn't expect that this dragon tooth sword actually had a sense of self...... Refuse to recognize the Lord!" Looking at this scene, Emperor Yu couldn't help but show bitterness on his face and sighed. "Success is also a dragon soul, defeat is also a dragon soul...... What a pity!"

"What a pity?"

Chen Han smiled and strode towards the Dragon Tooth Sword.

"Refusing to deny the Lord, having a personality...... I love it!"

After speaking.

With a wave of his big hand, he grabbed it fiercely.
