The Dutian Great Thunder Fire Seal is one of the treasures of the Heavenly Master Sect, and its power is endless.

The copper seal is jujube red, taken from the thunder jujube wood, the shape is clumsy and atmospheric, and the ancient Rui beast is carved.

It is said that it is imitated according to the Thunder True Fire Seal of the first Heavenly Master, which can suppress all evils.

At this moment, under Qin Hao's urging, the power was fully displayed.

"Shield!"

Wang Qu fingered, and a huge shield wrapped his body.

The horror is that the thunder fire did not go out, but with a shield, it burned fiercely.

The king's eyes widened, and his face showed horror.

The catalogue of the divine weapons he cultivates is purely condensed with true qi, not afraid of swords, and not injured by water and fire.

However, under the flames, it was difficult to support.

Seeing that the shield was burned into molten iron, Wang's fingers connected and condensed a huge fireproof cover to detain him.

"Hehe, it worked. ”

Seeing this scene, Qin Hao was overjoyed in his heart, and his true anger poured into the Dutian Great Thunder Fire Seal, condensing a blazing thunder fire.

The space seems to be unable to withstand this high temperature, and it becomes hot.

The ruins around it were even more scorched black, and the few golden pillars that were thick together had already turned into gold water.

Qin Hao didn't know.

The Dutian Great Thunder Fire Seal is made from lightning strike jujube wood, peach wood and jujube wood, which is the essence of the five trees of Taoism, and has the effect of suppressing evil spirits.

In particular, lightning strike wood is extremely rare.

In the copper seal, it contains the power of thunder, which is derived into flames, which is the thunder fire in the sky, and has the characteristics of the sun.

Although the king's strength is terrifying, and his body is not corrupted, his body is full of bloody energy.

This is the breath of filth, it is the breath of evil, when it encounters the scorching of thunder and fire, it is naturally the winter snow meets the spring sun, without the slightest resistance.

"Come to Tianlei and try it!"

Qin Hao's heart moved, and his true qi gushed out, condensing a thunderbolt, and hitting it out with the help of the Thunder Fire Seal.

Shout!

Thunder came in an instant and struck the king over his head.

Cracking sound!

A series of explosions erupted from the king's body, and I saw that his face was scorched black, and the aura on his body was slumped.

"Come again!"

The joy in Qin Hao's heart immediately condensed one thunderbolt after another.

"Damn it!"

The king was angry and unwilling.

Seeing that he was about to kill this hateful boy, such an accident happened.

He was forcibly resuscitated, but he has not yet recovered to his full glory, and his foundation has been greatly traumatized.

If he was suffering from a thunder fire attack, the injury would be even more serious, and it would have an immeasurable impact on his future cultivation.

"Next time, the Lone King will definitely kill you. ”

The king let out an unwilling roar, turned into a streamer, and quickly swept away.

"Next time, I'll kill you. ”

Looking at Wang's fleeing figure, Qin Hao's eyes were firm and he said solemnly.

Putting away the Dutian Great Thunder Fire Seal, I breathed a sigh of relief in my heart.

This battle was the most difficult battle in his life, and even if he defeated the king, it was a fluke.

Previously, he had crisscrossed all directions, slashed countless enemies, and established a strong self-confidence.

There is a world so big that there is nowhere to go.

After this battle, it seemed that a basin of cold water was poured on his head, giving Qin Hao a wake-up call, the world is so big, there are many strange people, and you must not be complacent.

If it was Wang Quansheng, he would definitely be the one who fled.

"Hey, this is ......"

Qin Hao rested for a while, and was about to leave the tomb, when the tip of his nose suddenly smelled a special breath.

After perceiving it carefully, Qin Hao's eyes opened and burst into joy.

"Is it really it?"

Qin Hao said in surprise.

Following the place where the breath floated from, Qin Hao quickly chased after him.

After traveling hundreds of meters, Qin Hao came to the end, there was no way in front of him, and he felt that this should be the belly of the mountain.

"This is it!"

After perceiving it carefully, Qin Hao said excitedly.

Bang!

He threw a punch, blasting the stone layer in front of him open, and suddenly, the cold aura became more and more intense.

Inside, there is no cave.

What appeared in front of him was a small cave.

In the center of the cave is a small pond, and strangely, the water in the pond is as black as ink, with a heart-deep coldness.

Streams of white smoke drifted from the pond into the air, and light smoke curled up.

In the center of the pond, there is a strange plant, about an inch long, with a dark green color that gives people a cold touch.

"Cathode grass!"

Seeing this plant, Qin Hao was overjoyed and exclaimed.

Cathode grass is a rare elixir, extremely precious, and only grows in shady and cold places.

Moreover, it is very difficult to grow, and it only takes a hundred years to grow a point.

At this time, the cathode grass is highly poisonous, and once it is taken, it will cause cold poison to attack the heart, even if it is the realm of a grandmaster, it will not last for a while.

Only cathode grass that is more than 500 years old has no toxins, and can refine pills and enhance spiritual power.

And the cathode grass in front of me is one inch and three minutes long, and it has grown for 1,300 years, and the medicinal effect is amazing.

If a martial artist who cultivates the Yin and Cold Exercises gets a cathode grass, with the help of the cold qi in it, it will greatly increase the cultivation speed.

In the cultivation world, the most well-known role of cathode grass is to refine the marrow cleansing pill.

The Pulp Cleansing Pill, as the name suggests, is to wash the meridians and cut the marrow, which can eliminate impurities and improve the cultivation talent of martial artists.

Even in the cultivation realm, it is very precious.

And refining the marrow cleansing pill requires the assistance of the monarch and the minister, one main and three auxiliary medicines.

The main medicine is naturally the marrow washing grass, which is an extremely rare medicinal material, containing peculiar effects and immeasurable value.

The other three medicinal herbs, although not as precious and rare as the marrow washing herb, are not ordinary.

They are: Jiuyun Cold Branch, Cathode Grass, and Polar Spirit Smoke Luo Flower.

Jiuyun Cold Branch, Qin Hao already has one in his hand.

At the Nantian Exchange Meeting, Qin Hao pressed the Medicine King Valley, and they didn't dare to take half a step out of the mountain gate, and in the end, Yao Yan bowed his head and softened, and compensated for the three spirit grasses.

One of them is the Nine Cloud Cold Branch.

At this moment, the cathode grass is in front of you, as long as you find the marrow cleansing grass and the extreme spirit smoke Luo flower, you can refine the marrow washing pill.

When the time comes, if you give Zheng Qingyun and her parents, you will be able to change your physique and let them also embark on the road of cultivation.

Thinking of this, Qin Hao's heart pounded.

Sou!

He was on tiptoe, and his body was like a bird's head in the forest, and he was about to sweep to the high platform and grab the cathode grass.

Hiss!

At this moment, a faint voice echoed in his ears.

Shout!

In the next second, a black shadow appeared in sight and rushed towards him.

"Get out!"

Qin Hao drank low in his mouth, and slapped his palm with all his might, shaking this black shadow out of the air.

In the palm of his hand, there was a huge anti-shock force.

Qin Hao didn't notice it for a while, his body fell down, and the soles of his feet stepped on the ink pool.

Click, click!

A bone-chilling breath emerged from the pool and climbed up along the soles of Qin Hao's feet.

A closer look showed that ice had formed on Qin Hao's legs.

Qin Hao's heart moved, and the power of qi and blood flowed to his legs, immediately shattering the ice, and he looked up at the black shadow.
