"Five years, where is five years enough. ”

Under the blue sky, the white clouds met, and Zhou Yu took a crane at this moment and headed towards the northeast of southern Xinjiang.

The matter of refining evil is very important, and if you can't find a suitable place to refine it, I'm afraid it will take more time.

And the reason why he made a five-year covenant was not only to set a goal for himself, but also to be just like what Mu Qingya thought in the end.

Zhou Yu was worried that he would be rashly involved in some kind of battle again, and if he couldn't get out of it at that time, there would be elders from the sect who would rescue him in time.

This can be regarded as a hole card he left for himself.

After all, the things of Shinto that made his own uncles and uncles taboo can be bumped into by him, and with the current situation in southern Xinjiang, it is difficult to say that he will not be involved.

However, he would not really let Mu Qingya wait for five years, as for the reason, after Mu Qingya read the information left by the jade slip, he would naturally understand.

But hearing that a woman is willing to wait for five years for herself, she is still inevitably moved. Thinking of Mu Qingya's smile at the end, the corners of Zhou Yu's mouth curled slightly.

It's a pity that he is a man who is destined for immortality.

"Although four of the seven hellish places recorded in the South Sword Palace are suitable for me, I still have to go to know the real situation. As soon as the words fell, the Liuyun Crane that was sitting on it increased in speed and flew away quickly.

Half a moon later, in a mountain range that stretched for thousands of miles, a blue-white sword light landed on one of the dry mountains from the sky.

"This is the place where the Eight Grades of Earth Evil, the Lonely Yin Wind Evil, are located. Looking at the extinct mountain in front of him, Zhou Yu's eyes flickered.

Different from the grade of the elixir and magic weapon, the earth evil wind cave is just the opposite.

The power of the Eight Rank Earth Evil is already the limit that ordinary Dao Foundation monks can withstand, such as the kind of foundation that builds with mana.

The seventh or even the sixth rank in the upper ranks is a comprehension that only true Daoji monks can challenge.

It is not that the higher the grade of the Earth Evil, the better, although the higher the grade of the Earth Evil Wind Cave, in a very short period of time, can make the monk's mana transform and greatly increase the strength.

But these can be compensated for with time, unless it is an extremely special kind of earth-shattering place, otherwise there is not much difference in terms of increasing the success rate of the Jindan Realm.

Of course, the increase in combat power of high-grade Earth Evil Wind Caves is much higher than that of low-grade Earth Evil Wind Caves, and some Earth Evil Wind Caves with special power are even more so.

This is also the reason why Zhou Yu chose this place, firstly, he wanted to see the strength of this lonely yin wind demon first, and secondly, after the wind evil sacrifice here, he could make the flying sword more sharp and swift.

The formation of the Earth Evil Wind Cave has a long history, but it is probably a change in the power of the leylines.

The precipitation of spiritual energy between heaven and earth can form meridians in the mountains, and the convergence of the power of the earth's leylines can also form all kinds of strange places, just like this place with a lonely yin and evil earth.

However, after a stick of incense, Zhou Yu came to a valley mouth.

There is a huge cave in this valley, and in that cave, there is a yin wind howling out, but due to the changes in this valley and the surrounding mountains, a wind evil circling in the valley is formed.

As the saying goes, the solitary yin does not grow and the yang does not grow, so this valley, and even the entire mountain, in the flood of this yin and evil power, does not give birth to a single grass or tree.

Looking at the black storm that enveloped the entire valley, there was a hint of amazement in Zhou Yu's eyes.

Although the wind did not appear to be violent, it was actually extremely sharp, and wherever it swept through, the walls around the valley were marked with sharp wind blades.

"It's just an eight-grade Earth Demon Wind Cave, but the power of this wind blade is already comparable to the power of a top-grade magic weapon with three Heavenly Gang Forbidden Paths.

No wonder Mu Qingya would recommend this place, this place is indeed suitable for sword cultivation and sacrifice. Feeling the power contained in the lonely yin wind, Zhou Yu was shocked.

"Try it first. ”

As soon as he thought of this, Zhou Yu suddenly shot out a mana and headed towards the lonely yin wind in the valley.

Different from the milky white mana before, after the transformation of the Five Elements True Beginning, the mana is separated from the body at this moment, faintly emitting a colorful light.

And the mana of the Five Elements True Origin Recipe is more cohesive and strong than ordinary mana, which makes Zhou Yu a little worried, whether this lonely yin wind in front of him is the best choice.

As the mana entered the edge of the lonely yin wind, an extremely cold aura suddenly swept in.

And in this breath, there is a sense of swiftness that tears everything, not so much the wind as the blade.

"Huhuhu......"

Zhou Yu maintained his mana and allowed the black wind to whistle and collide with each other.

As soon as the two approached, Zhou Yu felt that the mana was cut and began to be unstable, but the mana of the Five Elements True Origin Technique was obviously more tenacious and was not defeated by a single blow.

As soon as he thought of this, Zhou Yu used mana to wrap the wind and evil qi in it.

Buzz Buzz......

In a trance, the sound of a whetstone sounded, and I saw that the mana that was shining with the five-colored light, under the polishing of the lonely yin wind, began to cultivate, stained with a trace of black.

But as Zhou Yu refined the evil qi in it, the speed suddenly slowed down.

According to his estimates, if this fist-sized mass of five elements mana is to be fully refined, there will be at least half a cup of tea.

And this fist-sized mana is less than one percent of Zhou Yu's, if it is really practiced with this wind and evil sacrifice, I am afraid that the time for complete transformation will be at least more than seven years.

"Although the Earth Evil Wind Cave here is suitable for sword cultivation, its strength is not suitable for me, and if I practice it with this, I am afraid it will take a lot of time. Seeing this scene, Zhou Yu shook his head regretfully.

Maybe he will come back here when he really can't find a suitable Devil's Wind Cave, but he doesn't think about it for now.

As soon as he thought of this, Zhou Yu cut off the connection with the mana.

In just a few breaths, the fist-sized five-element mana quickly dissipated in this wind force.

"The strength of the Eight-Rank Earth Evil Wind Cave is not enough, so let's start directly from the Seventh Grade. Thinking of this, Zhou Yu took the sword and flew towards the northwest of here.

If the information is good, about 900 miles away from here, there is a seven-grade away from the dust.

Although the mana after this evil sacrifice is not as fast as the Lone Yin Wind Demon, it has a little more weight and confusing power.

Once the imperial envoy flies the sword, it can make the sword qi produce the effect of flying sand and stones, which is extremely suitable for sword cultivators or other monks who cultivate the earth-line sword technique.

But seven days later, after coming here for some testing, Zhou Yu gave up.

It's not that I can't see the sand and rocks.

Okay, I just can't see the sand and rocks.

His sword is not a sword that focuses on confusion, and the characteristics of this flying sand and rocks are not as good as the previous solitary wind and wind for him.

Before he came here, he thought there would be some other changes.

However, through the detection of these seven grades of dust and evil, Zhou Yu also roughly judged the appropriateness of the earth demon sacrifice that he could accept now.
