By refining demon beasts and devouring essence blood, to improve one's own cultivation, this way is of course domineering and direct, clean and neat, but while devouring the essence blood of those demon beasts, it also has some negative energy, pervasively eroding Zhou Yun's Dao heart will, as if he wants to turn Zhou Yun into a beast that only knows killing and bloodthirsty.

"It's too up-and-coming star, and the strain doesn't stop...... Exorcise evil spirits and protect your life...... Wisdom and clarity, peace of mind...... The three souls are eternal, and there is no loss of soul. ”

At the level of Dao Heart's will, the moment of negative energy appeared, Zhou Yun's mouth was filled with a mysterious and distant chanting.

This interprets a certain subtle and quiet chanting, like an immortal ballad that came from that ancient era across the long river of time, and like a piece of heavenly music pouring down from the nine heavens!

This is the "Purifying Mind Mantra"!

Chanting this mantra can not kill the enemy, but it can prevent all evil from invading and purify the mind.

As for the origin of this "Pure Heart Curse", it is resolutely a great avenue secret technique in "Three Thousand Daozang".

To put it mildly, "Daozang Three Thousand", that is from ancient times to the present, the most ancient, the most mysterious kind of supreme Taoist canon, it is rumored that this "Daozang Three Thousand" is fully enlightened, then you can ascend to the fairy world, lift the sun and soar.

After the primeval era, "Daozang 3000" disappeared, even those ancient emperors who were proud of the world and respected in the universe could not collect the entire "Daozang 3000", and they could get a secret technique in "Daozang 3000", which was a gratifying and joyful thing.

Zhou Yun in the previous life, deep in the devil's way, did everything, did all kinds of evil, once in a secret realm, accidentally learned of a fragment of the "Three Thousand Dao Collections"! This can be said to be a creation of the sky.

The complete "Three Thousand Daozang" is divided into nine volumes, which add up to twenty-seven volumes. The volume of "Three Thousand Dao Collections" that Zhou Yun got was not complete, but it also recorded dozens of supreme secret techniques!

Today's Zhou Yun is trying to refine demon beasts through the "Demon Emperor Devouring Heaven Sutra", so as to suddenly and quickly improve his cultivation to the Dao! Then he will suffer from the backlash of negative energy, even if Zhou Yun's Dao heart is strong and his will is immortal, it will leave some hidden dangers, but with the assistance of this "Pure Heart Divine Mantra", it will be completely different.

The effect of the "Pure Heart Mantra" can be called the most subtle method of meditation and exorcism throughout the ages. It can also be said that as long as it originates from the Taoist secret techniques in "Three Thousand Dao Collections", it is supreme and unique.

......

In the past month, the white horse has passed by in the blink of an eye.

In this month, Zhou Yun was unscrupulous, refining the Great Wilderness Beasts he encountered day and night.

For the rest of the month, Zhou Yun refined more than five hundred demon beasts!

These more than 500 demon beasts are all demon beasts within the scope of the Spirit Vein Realm.

"Nine Peaks of the Spirit Vein Realm!"

Zhou Yun, who was dressed in a green shirt, walked out of the dense forest and came to a lake.

His cultivation at the moment has reached the peak of the Spirit Vein Realm, his qi is perfect, and his blood is majestic, as if he can break through to the level of the Foundation Building Realm at any time.

"There's no rush. ”

"The breakthrough between the great realms, that is particularly important, is still precipitating. ”

Zhou Yun looked up at the front, in front of the wide lake that was as clear as a jewel, the grass and trees were abundant, and the flowers and plants were abundant.

A black python more than ten meters long, with thick scales, cold eyes, and sharp fangs entrenched there.

"Build the foundation realm!"

This is a foundation-building realm-level demon beast.

"In the past month, all I have refined are only spirit vein realm-level demon beasts. The essence blood energy of this beast is comparable to a hundred spirit vein realm ninefold demon beasts!"

Looking at the black python that exuded an inexplicable deterrent, outside of Zhou Yun's fair face, there was no fear at all, only high battle intent and eager greed.

"Hiss"

The black python, who noticed the figure of the young man, did not rashly and recklessly take the offensive.

Demon beasts are naturally sharp!

In the induction of the black python, the harmless man in front of him, the young man in the green shirt who was weak and couldn't help the wind, was far inferior to himself in the realm, but it brought himself a sense of mortal crisis.

"Devour the heavens and eat the earth, refine the blood and turn the essence!"

The high-spirited, domineering and awe-inspiring Zhou Yun, no matter what the black python thought, his hands were sealed, the blood light was filled, and the runes were thousands, and in an instant, a blood-colored furnace with a vague outline and a mysterious totem was covered by the black python's body.

"Roar Roar"

The black python was crazy, and he went on a rampage desperately in the blood-colored furnace, spitting poisonous mist.

Zhou Yun didn't give this evil animal a chance to escape, the wind was under his feet, and he only fell on the blood-colored flood furnace, like a vigorous and domineering ancient god, suppressing everything and destroying the black python in the blood-colored furnace!

These are two completely different realm levels, and the gap between them is as insurmountable as a chasm.

But just in front of this lake, Zhou Yun, who was hunting in clothes and black hair, was flying wildly, his body was straight, and he was standing on the blood-colored furnace with a mountain and river, no matter how the black python collided and roared, it was still refined into a ball of essence and blood energy after all.

"Whew"

Zhou Yun, who swallowed this mass of essence and blood energy, crackled his muscles and bones, his blood and qi came out of his body, and his aura boiled and roared.

This is a sign before the breakout.

As long as Zhou Yun is willing, he can completely use the essence and blood energy of the black python to rush into the foundation building realm level with the momentum of breaking the bamboo.

But somehow, on the verge of this breakthrough, Zhou Yun had an illusion that it was not very complete, as if there was still a road under his feet.

Is it just a delusion?

Wrong!

Zhou Yun trusted his instincts.

He's not ignorant, he doesn't know anything.

The cultivation experience of the previous life was Zhou Yun's greatest reliance.

Suppressed the great temptation of taking a step into the foundation building realm!

Zhou Yun sat in front of this mist, clear and crystalline lake, refining his cultivation little by little without stepping into the foundation building realm, trying to walk out of the path again under the realm of the ninefold peak of the spiritual vein realm!

One day, two days, ten days...... Past.

The young man in front of the lake, his body is bright, his forehead bone is shining, and even the bones under the flesh and blood are all brilliant and looming.

The most wonderful thing is that Zhou Yun, who was bathed in that divine light, had an obscure qi and uncertain cultivation, and he had obviously not yet stepped into the foundation building realm, but that cultivation was qi and was not inferior to ordinary foundation building realm monks.

Another ten days passed.

The sky in front of the lake is dyed with a depressing dark color.

After a while, the rain was pouring down, and the lightning flashed and thundered.

Zhou Yun, who was sitting there, did not move at all, and his treasure was solemn.

Abrupt.

Above the sky, there is a lot of thunder.

This piercing and deafening sound of heavenly thunder instantly spread to every inch of the Great Wilderness, and the thousands of demons and beasts that thrive in this Great Wilderness are all trembling and trembling.

Under the thunder of the sky, Zhou Yun bore the brunt of the attack! The cultivation state that was as steady as a rock and as still as water was also almost interrupted.

In practice, the most taboo thing is the intrusion of external forces, and under this sudden change, it is very easy to go mad and die.
