As for the Yin Demon Bead, although it seems to be the level of a medium-grade magic weapon in terms of grade, and it is much better than the bone rod of a lower-grade magic weapon, Ye Ping really doesn't want to waste it, because this Yin Demon Bead is even better than a high-grade magic weapon in his eyes, because he has the effect of self-upgrading, if he refines now, then if he wants to upgrade himself in the future, it will be a bit difficult.

Since he had decided to refine this heel bone stick, Ye Ping did not hesitate.

After adjusting his state, he silently ran the yin and evil qi in his body, and then controlled the bone stick with his heart, so that more yin and evil qi bloomed in the bone stick, and first let this bone stick have a full meal to achieve a better state.

At this time, when he felt more yin and evil qi surging in, he became very active and began to smoke wildly.

Taking advantage of this opportunity, Ye Ping carefully comprehended the yin and evil qi absorbed in his body very seriously.

This is also when he used the blood sacrifice method, he suddenly had an idea, and he thought of using this yin evil qi to cooperate with the refining of this bone stick, which should be able to play an unexpected role.

Soon, the Yin Evil Qi released by Ye Ping was quickly sucked up by this bone stick, and the state of this bone stick reached its peak, and it grew a little stronger.

The purpose of making the bone stick grow in this way is to make the essence core of the yin and evil qi in the bone stick more solidified.

And at this time, Ye Ping suddenly locked on this bone stick with his mind, and began to use the yin and evil qi of the supreme yin to fuse the essence core in the bone stick.

The essence nucleus in this bone rod suddenly trembled, and he felt an extreme danger, so he dodged and jumped around in the soul cultivation array, and even kept howling, trying to escape the devouring of the essence nucleus by the yin and evil qi of the yin. (Baidu search update is the fastest and most stable)

Ye Ping was also using this method for refining qi for the first time, and it was inevitable that he would be a little rusty.

Every time I finally find the essence nucleus in the bone rod. But the essence core escaped by constantly struggling to escape.

However, as Ye Ping began to gradually become familiar with Devouring, the essence nucleus was scurrying around. There was no way to escape Ye Ping's search for his essence core.

Soon, in the midst of the howl of the nucleus. His essence core was found by Ye Ping and successfully locked, no matter how violently he struggled, he could not escape the fate of being controlled by the essence core.

When the essence core was locked, Ye Ping quickly entered the body of the bone rod with the yin evil qi injected into the yin, and through the baptism of the aura, as well as the coercion of the aura on the essence core, the essence core could only tremble, curled up and did not dare to make the slightest movement. He could feel that as long as he dared to struggle harder, his essence core would definitely not be able to withstand the coercion of that aura and be destroyed.

After Ye Ping saw that the essence core was suppressed, he probed his mind into the bone rod.

However, after the essence core shook violently twice, it began to struggle again, but then a huge spiritual pressure pressed towards it like the top of Mount Tai, and the essence core in the bone rod seemed to be unable to bear it anymore, after expressing obedience in constant wailing. Only then did Ye Ping's mind smoothly enter his essence core.

After leaving a mental imprint in the essence core, this essence core can no longer raise any instinctive fluctuations of resistance at this moment, his survival. It was already completely in the hands of Ye Ping's mind.

Taking this opportunity, Ye Ping had a new idea, and while he continued to familiarize himself with the use of the yin and evil qi in his body, he tried to slowly use this method to help this essence core with yin and evil qi purify the spirit core.

However, this step is a bit dangerous, and a careless step may not only wipe out this essence core, but also may cause Ye Ping's mind to be affected by some negative energy.

So Ye Ping is very cautious about this process, and he just tries it and tastes it.

But unexpectedly, Ye Ping just tried it like this. After transferring some of the impurities in the sperm nucleus of this bone rod to the bone rod itself, it received an unexpected miraculous effect.

This is just the bone rod itself, which has been purified of the essence core. Unexpectedly, in a fluctuation, there was a fluctuation of pleasure and surrender to Ye Ping. This was completely unexpected by Ye Ping.

It was only after trying it that Ye Ping finally realized the wonder of controlling the yin and evil qi at this time, and he couldn't help but admire the evil cultivator who was able to refine this bone rod even more.

Now that this bone stick is only a little bit of Ye Ping's attempt to purify the essence core, he will behave like this, so if Ye Ping continues to help him purify it in the future, the loyalty of the essence core in this bone stick will probably get higher and higher.

However, Ye Ping only tried it for the first time, and he didn't plan to continue, feeling that after this essence core was happy to surrender, it would be more convenient for him to go through the next blood sacrifice process.

So, Ye Ping's mind was drawn, and he controlled the bone rod to release the essence core of the yin and evil qi inside.

The released essence nucleus still looked very happy, as if it had been in the bone stick for a long time, and as soon as it suddenly came out, it continued to wander and dance around Ye Ping's body.

"Come here!"

Ye Ping's mind was still locked on this essence core, and when a wave of thought came out of his mind, this essence core quickly floated to Ye Ping's side, motionless, very obedient.

Under normal circumstances, Ye Ping would have to spend a lot of effort and effort to be able to suppress this essence core, and then spend a lot of mind and aura to make him communicate with this essence core before proceeding to the next step of the sacrificial refining process.

It's just that now, the first two most energy-consuming and aura-consuming processes were successfully completed in just a short period of time, but they saved Ye Ping a lot of time and a lot of aura, and even his mind was not too consumed.

This is the beauty of the yin and evil qi devouring the yin and evil qi.

And Ye Ping's clever application of it supplemented by the process of refining bone rods will bring more unexpected and huge gains to Ye Ping in the future.

The essence core of the bone rod is branded by the master's divine soul, and this method of controlling the essence core can be said to be extremely clever in the evil cultivation, which can be called the top.

That evil cultivator was able to create this heel bone stick, and now, with just that evil cultivator's means, he could easily subdue an evil creature who was at least a fourth-level zombie and dominate one side.

The deeper Ye Ping felt about this, the more he felt the power and profundity of that evil cultivator.

At this time, Ye Ping had actually completely controlled the life and death of this essence core in the bone stick, as long as his mind moved, this essence core would disappear directly.

Moreover, the Lord is destroyed!

In other words, the current essence core has become an evil fetus raised by the yin evil qi in his body, and it is refined and cultivated by the yin evil qi in his body, but Ye Ping still doesn't know what kind of evil fetus will be born after it breaks the cocoon!
