Wan Ku Peak, one of the secret rooms in the Xuanyin Evil Qi Cave.

"Lord Meng Chuan, please. A steward pushed open the stone door and said respectfully.

Meng Chuan nodded and entered the Xuanyin Evil Qi Cave.

Xuanyin Evil Qi Cave, an hour requires fifty merits, because the 'Xuanyin Evil Qi' is a relatively precious and rare evil qi, and it has a use for many powerful gods and demons, if you cultivate in the 'A-Number Secret Room', it will take five thousand merits for an hour. However, the concentration of evil qi in the 'A-number secret room' is far from what a mortal person can bear.

Even in the C-shaped secret room, many geniuses are in danger of getting into their brains and becoming confused.

"It's cold. "Meng Chuan walked into the secret room, the door of the secret room was closed, and a faint black mist filled the secret room, these black fogs were 'Xuanyin Evil Qi', a cup of boiling hot water fell down, and it would freeze into an ice lump before it landed.

And Meng Chuan has gone through the first six refinements, but it is enough to withstand this Xuanyin evil qi.

Evil qi invades the body and impacts the mind and the sea of consciousness.

The power of the Yuan Shen protects the sea of knowledge, so that the evil qi cannot invade the slightest, and still maintains absolute sobriety!

"Let's get started. "Meng Chuan once again used the corresponding body refining knife method, each evil qi has a corresponding body refining knife method, and under the guidance of the knife intent, the strength of the body is deeply mobilized, and the body is also allowed to absorb these 'Xuanyin evil qi'.

However, when it came to the seventh refinement, even if it was the sword realm, the absorption speed was much slower, but fortunately, he was able to stay absolutely awake! This was where Meng Chuan had an advantage over the other disciples.

Perform the Body Refining Knife Technique over and over again.

After the tea, Meng Chuan stopped.

"Practiced?" Meng Chuan smiled, he felt that his whole body was fused with Xuanyin Evil Qi, and Xuanyin Evil Qi completely changed his physique! Every refinement is a physical change, and everything is preparing for the final breakthrough of life and death, so as to achieve the 'Thunder World Destroying Demon Body'.

Meng Chuan stretched out his fingers.

There was a gray-white evil qi on the fingertips, which was the evil qi formed after the fusion of the previous seven refinements.

"For the seventh refining, it took me fifty-three days. Meng Chuan nodded slightly, "This speed is extremely fast in the book records." ”

"When you reach the Seven Refining Realm, you can go to lead the Heavenly Thunder through the life and death barrier. But the Thunder World Destroying Demon Body that was practiced like that can only be regarded as a small Demon Body. Meng Chuan was not satisfied, although Xiao Cheng's Thunder World Destroying Demon Body was still superior to all other gods and demons in terms of speed alone. It can be compared to the Thunder Exterminating Demon Body of the Nine Refinings, regardless of the strength, speed, vitality and other aspects, including the purity of the True Yuan Essence and the power of the thunder and evil qi in the body, it will be much worse.

"I still need to go through the eighth and ninth refinements. ”

"According to estimates, the speed of the eighth refining will continue to decrease sharply, and it may not even be able to be practiced. Meng Chuan understood this.

His cultivation efficiency is very high, his cultivation is very fast, and the total time for his body to be eroded by evil qi is also short. So there has never been a danger of 'physical collapse'.

But the evil qi of the eighth and ninth refinements is too terrifying.

"The eighth refining, the Golden Crow, is the top three destructive evil qi in the world, the most masculine and strong, blazing and furious, too destructive to the physical body. You have to rely on external forces to assist in cultivation, and the cultivation process is extremely painful. Meng Chuan frowned slightly, the golden black is very precious, Yuan Chushan was sold to the inner disciples one by one. A small bottle of Golden Crowsha with a large slap will require a hundred merits! The entire Eighth Refining Cultivation requires one hundred and twenty bottles of Golden Crowsy.

"The ninth refinement, the Six Desires, is one of the most mysterious evil qis, mysterious and abnormal, constantly integrating into the body and even more into the soul. If the power of the primordial god is resisted, the soul will not be able to absorb it. Meng Chuan also knew the difficulty of the ninth refining, "I can't use the power of the Yuan Shen, I must exercise my will." ”

To reach the gods and demons of the Great Sun Realm, you need your own will to reach the top of the Dark Altar.

And in order to successfully smelt the Six Desires, the will requirements are several times higher!

The Six Desires are precious.

A small vial of the Six Desires requires three thousand merits! The preciousness is far greater than that of the Golden Crow, and the completion of the ninth refinement requires a full ninety bottles of the Six Desires. That adds up to 270,000 credits!

Fortunately......

There are some special cases where you can pick it up for free.

For example, a mortal disciple who cultivates the Thunder World Exterminating Demon Body can receive the 'Six Desires' for free when he reaches the Eight Refining Realm, but every time he receives it for free, the seniors of Yuan Chu Mountain are sure that the previous bottle has been thoroughly refined.

......

Meng Chuan knew that the next eighth and ninth refinements would be very difficult, but once he achieved it, his strength would be much stronger in the future. Now that he is suffering, he can kill more demon kings in the future, of course he has to fight.

"Whew. ”

Leaving Wankufeng Peak, Meng Chuan used his body to go to his cave.

"Huh?" The god and demon 'Tianxinghou', who had just come out of a demonic cavern, saw Meng Chuan passing by from a distance.

Tianxinghou has a handsome appearance, and there is a flame mark in the center of his eyebrows, which is rare among the gods and demons of Fenghou who is good at bows and arrows, and is enough to rank in the top five among all the gods and demons in the world in terms of bow and arrow skills. As an archer, he also practiced the pupil technique! A pair of eyes saw that Meng Chuan...... The aura in Meng Chuan's body flowed, and the power surge was all under his observation, and he also saw the evil qi that was melting in Meng Chuan's body.

"Xuanyin evil qi has also been successfully integrated, and the seven refinements have been successful?" Tianxinghou was surprised, "This Meng Chuan, and my disciple Liu Qiyue's childhood sweetheart, should have just entered Yuan Chu Mountain at the end of last year." It's only been more than half a year, and you've already cultivated to the seventh refinement?"

Seven refinements are a threshold.

Reaching the Seven Refinements means that you have been able to achieve the Thunder World Destroying Demon Body. The powerhouses of the Thunder World Destroying Demon Body are all extremely fast, and their role in the war is very large.

"He was just about to leave Ten Thousand Dry Peak, and the refining should be over. "Tianxing Hou is clear," and the eighth and ninth refinements of the Thunder World Destroying Demon Body are the Golden Crow and the Six Desires, and they don't need to come to Ten Thousand Dry Peak at all. So he just finished seven exercises today? Well, this news has to be told to the mountain master immediately. ”

Sou.

The Celestial Star Marquis disappeared in place in a flash.

Dongtian Pavilion.

The long-haired man was leisurely drinking tea in the pavilion, while the purple-robed Yuan Chu Mountain Lord walked over.

"Your Holiness. The mountain lord of the beginning of the Yuan Dynasty spoke.

"Wenyou, why did you come to me?" the long-haired man smiled.

The Yuan Chu Mountain Lord immediately said, "Venerable, the Heavenly Star Marquis told me that when he saw his new disciple Meng Chuan, he was sure that he had reached the Thunder Exterminating Demon Body Seven Refining Realm. ”

"Oh, I don't know about it yet. The long-haired man smiled, "Since it was said by the Marquis of Tianxing, it won't be wrong." By the way, there's one thing I didn't tell you. ”

The mountain lord of Yuan Chu looked at the long-haired man suspiciously.

"Meng Chuan reached the artistic conception of the knife more than two months ago, and practiced the Black Iron Heavenly Book "Heart Knife". The long-haired man smiled, "I guess he should reach the Seven Refining Realm soon, and it's really not bad." ”

"What, have you practiced the Black Iron Heavenly Book?" The Yuan Chu Mountain Lord was even more excited and happy, the super god and demon body combined with the Black Iron Heavenly Book, Yuan Chu Mountain was going to have one more powerful god and demon!

"The Black Iron Heavenly Book can't be inherited, and he has practiced it so quickly?"

""Knife of the Heart" suits him very well. The long-haired man said.

"Then which trick did he practice?" asked the Yuan Chu Mountain Lord.

"The first move is 'heart knife style'. The long-haired man said.

The mountain lord of Yuan Chu was even more happy, and nodded again and again: "Okay, well, the 'Heart Knife Style' is the root of all the tricks of the entire "Heart Knife"! Condensing the sword intent with this move, it's really good, it's wonderful!"

"Okay, you are a mountain master, aren't you just a disciple who has cultivated into a super-grade god and demon body and black iron heavenly book, why are you so excited. The long-haired man said calmly.

"Of course I'm happy to have one more powerful god and demon. The mountain lord of Yuan Chu smiled.

The long-haired man was in a complicated mood, and said: "I have seen many powerful gods and demons with outstanding talents, and they rose and dazzled for a while, but they fell one by one over time. In the past 800 years, there have been too many fallen gods and demons. ”

Even if Meng Chuan has a primordial god in the ordinary world, even if he has cultivated into a super-grade god and demon body, and the Black Iron Heavenly Book, the Venerable is not too excited, but he is in a complicated mood, and he has seen the rise of a similar peerless genius too many times.

"As long as there is a steady stream of powerful gods and demons in our human race, we will definitely be able to defeat the demon race in the end. The mountain lord of Yuan Chu said.

"There will be that day. The long-haired man also had a hint of fierceness in his eyes.
