At the top of Funiu Mountain, among the wooden houses surrounded by spiritual mist.

The spiritual power fluctuations on Chen Hao's body became more and more intense, and when he reached the peak, he turned calm in an instant.

"Shhh

A burst of inhalation suddenly sounded in the wooden house, and immediately I saw that the rich aura in the wooden house, in the blink of an eye, actually converged into a salute and surged towards Chen Hao's mouth.

A minute later, the aura in the wooden house completely disappeared, and Chen Hao's figure was completely revealed.

At this moment, he was calm, and his injuries had fully recovered, but the whole person was still pitch black, like a black man.

Suddenly, Chen Hao's eyes opened, black smoke in his right eye, and light in his left eye, which instantly erupted from his eyes, and in an instant, he returned to calm.

"After three hours of hard work, I finally recovered from my injuries, and the next step was to expel the toxins. ”

"According to what the ghost cultivator said, if you want to expel the toxin, you must make the Heavenly Thunder Stone into a pendant and wear it for three days before you can eliminate the poison of the Yan Flower in your body. ”

"However, instead of making a pendant, why not refine the Heavenly Thunder Stone and integrate it into the fragments of the Qinglong Sword to re-refine a flying sword. At that time, the Qinglong Sword has thunder power, and it will become a great weapon for destroying ghost cultivators. ”

The light in Chen Hao's eyes flickered, and he instantly decided in his heart.

Then, with a flip of his palm, a fragment of the Blue Dragon Sword suddenly appeared on his palm.

Looking at the fragments of the Blue Dragon Sword that were shattered for the second time, Chen Hao's eyes twitched a little, and he immediately put it on the couch in front of him.

Then, take out the Heavenly Thunder Stone again.

The Tianlei Stone is dark, not a stone in the ordinary sense, but a little like the condensation of ferric tetroxide. And, on the Heavenly Thunder Stone, small arcs can be seen crackling from time to time.

Chen Hao took a deep breath, and then threw his palm, and the Heavenly Thunder Stone instantly fell into the air, and under the gravitational technique, it was quietly suspended.

Then, with a flick of Chen Hao's fingers, a ball of spiritual fire instantly flew out from his fingers, and after landing on the Heavenly Thunder Stone, it suddenly surged warmly, wrapping the entire Heavenly Thunder Stone and burning violently.

After scorching for an hour, Chen Hao was speechless and found that the Heavenly Thunder Stone did not show a trace of melting, and it was still strong.

But Chen Hao does not believe in evil.

The magic tricks in his hand were pinched faster, and one after another spells hit the spiritual fire, and in an instant, the spiritual fire burned more violently, the temperature rose even higher, and the wooden house was hot.

Two hours!

Three hours!

......

Twelve hours!

It took a whole day, in front of Chen Hao, the floating Heavenly Thunder Stone finally showed a hint of melting, and at the same time, on the Heavenly Thunder Stone, the arc jumped more intensely, and the crackling sound echoed in the wooden house.

When twenty-four hours passed, two full days passed.

In front of Chen Hao, the heavenly thunder fossilized into a dark liquid, and the arc on it flickered, which was very amazing, but Chen Hao's eyes were emitting an excited light.

The stronger the thunder power of the Heavenly Thunder Stone, the higher the difficulty of melting, then, the Qinglong Sword he finally refined, the toughness will be greater, the strength will be stronger, the less likely it will be broken, and the power will also increase greatly.

Chen Hao took a deep breath. He didn't rush to refine the fragments of the Qinglong Sword, but closed his eyes and breathed to replenish the spiritual power he had lost in the past two days.

At that time, he will refine the Qinglong Sword with the fullest spirit, and strive to improve the quality of the Qinglong Sword to a great level.

An hour later.

Chen Hao opened his eyes and glanced at the Heavenly Thunder Stone melt in front of him. Then he stretched out his hand and grabbed the fragment of the Blue Dragon Sword in the air. When he landed, the fragments of the Qinglong Sword were started. Then, it was thrown into the air.

Slowly, the fragments of the Green Dragon Sword were scorched by the spiritual fire, gradually turning into a light blue liquid.

When the fragments of the Green Dragon Sword were melted, Chen Hao stretched out his finger and volleyed a little into the air. In an instant, the Heavenly Thunder Stone melt and the Blue Dragon Sword fragment melt slowly approached.

Rumble!

The two masses of liquid collided together, and the strong icy energy and the violent arc of thunder collided violently, and in an instant, a strong roar erupted, echoing inside the wooden house and spreading in all directions on the top of the mountain.

Chen Hao's face was calm, and his fingers flew, bringing up afterimages. Spiritual fingerprints formed between Chen Hao's hands, and then landed on top of the two masses of liquid.

Time passed slowly, and under Chen Hao's continuous matchmaking, in the end, the two liquids fused together and turned into a ghost-like black liquid.

At this point, Chen Hao's spirits were lifted, and his eyes were bright.

His right hand suddenly stretched out, and his sword pointed out, and a thread-like aura fell on the black liquid.

"Edict!"

A cold drink suddenly came out of Chen Hao's mouth.

In an instant, his sword fingers trembled, and the aura on it flickered, pulling the black liquid and constantly changing its form.

At the end, a spirit sword that was a few feet long, completely black, glowing with cold air, and flashed with electric arcs, and crackling sounds, appeared in the air.

Chen Hao saw this.

Flipping his palms again, one after another spell seals were shot out and landed on top of the black sword.

After a while, the black sword was very agile, and strange ripples emanated from the black sword.

A certain moment.

The black sword suddenly rang out with a soft roar.

Chen Hao's spirits perked up, and the momentum of pinching his hands slowly stopped. In the end, Chen Hao's thumb swept across the belly of his middle finger, and immediately, a drop of essence blood was forced out of the body, but above the essence blood, there was black smoke.

Chen Hao flicked his middle finger, and the drop of essence blood flew away from the black sword.

When he reached the black sword, he was about to pour into the body of the sword. But suddenly, above the black sword, a dazzling arc of light rushed out, directly enveloping the essence blood.

Seeing this, Chen Hao's eyes froze, and the essence flashed.

Then, it's just about hearing.

Bang bang bang!

Like the sound of dry wood burning, it suddenly sounded in the wooden house.

That drop of essence blood, wrapped in arc light, turned bright red in an instant, and the black smoke on it actually dissipated and burned into nothingness.

Then, the essence and blood flashed, falling on the body of the black sword, and slowly integrated into the fitness.

Chen Hao's body shook suddenly, and he suddenly felt an inexplicable mental connection appear in the bottom of his heart.

It seemed that all of a sudden, the black sword seemed to have turned into a third arm, wielding freely with the thoughts of his mind. And this kind of feeling, the former Qinglong Sword, did not have.

"It seems that after merging with the Heavenly Thunder Stone, the Qinglong Sword has been promoted again and has become a high-level magic sword. ”

Chen Hao's eyes flashed, he stretched out his palm, grabbed the black sword in the air, and then grabbed the black sword into his hand.

Suddenly, Chen Hao felt a feeling of blood connection.

"You are based on the Green Dragon Sword, but you are no longer the Green Dragon Sword, from today on, your name, Heavenly Thunder Sword. ”

Chen Hao looked at the black sword and smiled faintly.

Then, as if whispering to the black sword, he said, "Next, you help me expel the poison of the Yan Flower and return to normal." ”

Chen Hao threw his palm, and immediately, the black sword soared into the air, flew to the sky above his head, and the tip of the sword pointed down at the top of Chen Hao's head, turning into more than a meter long.

The arc of electricity on the sword flickered, and there was a slight thunderous sound.
