So far, Xu Tui has never used the source of mental power crystal.

But he is very clear about the value and role of the spiritual power source crystal.

The mental power source crystal has two functions. One is to use it as an ordinary source crystal, absorbing the energy inside and using it for cultivation or recovery of injuries.

But generally speaking, no one would be so wasteful.

The most valuable function of transparent mental power source crystal is to directly restore mental power.

If Xu Tui's mental power is excessively exhausted and he faces an extremely dangerous situation, he can directly absorb the mental power source crystal to restore his mental power.

This kind of recovery is recharged in seconds!

It can also be used to treat some mental injuries.

It can be said that for new humans with mysterious genes, spiritual power source crystals are too important, and they can be called the most important and important strategic materials.

Of course, this kind of instant charging is also a bit troublesome.

All spiritual power source crystals retain the spiritual will of the original owner. Direct absorption can restore spiritual power, but the remaining spiritual will of the original owner will impact the absorber to a certain extent.

It will briefly impact the absorber's spirit. In more serious cases, this impact will shock the absorber's spirit and even cause hallucinations and confusion.

As for the duration, it depends on whether the master's spiritual will is strong or not, as well as the absorber's spiritual will.

It doesn't matter in peacetime, but it is very important in wartime.

However, humans are very smart in this regard.

An Xiaoxue knew that Xu Tui had obtained two transparent spiritual power source crystals from Xia Mira.

I asked Xu Tui to preprocess these two pieces of spiritual power source crystal first.

It means to first absorb a small amount of energy in the spiritual power source crystal, and first induce the remaining spiritual will inside to eliminate hidden dangers.

Although this will result in a loss of 10% to 20% of the volume, there is no hidden danger.

When you are really in a critical moment to restore your mental power, you can use this thing to replenish your mental power instantly.

For new humans with mysterious genes, having one of these things is equivalent to gaining half of their lives.

Therefore, Xu Tui has never dared to use the two spiritual power source crystals he obtained from Mira this summer.

Just prepare it for emergencies and use it to replenish your mental energy instantly.

Therefore, Xu Tui actually had two spiritual power source crystals in his hand at this moment.

But Xu Tui was hesitant.

Should we use these two spiritual power source crystals for experiments?

This thing is actually quite precious.

At the official price, one gram of spiritual power source crystal can be exchanged for two grams of other types of source crystal.

But this is only the official price.

According to Xu's experience, the price of such scarce emergency items in the private market will only be higher.

Maybe three times or even four times.

For testing, Xu Tui was really hesitant.

It would be fine if this comes to fruition, everything can come back.

If this doesn’t work, it will be a big loss for Dafa!

"If you don't want to let the child catch the wolf, leave one piece and try it." With a cruel heart, Xu Tui made the decision.

"Yan Lie, if you stay vigilant for a while longer, I have an idea I want to try," Xu Tui said.

"good."

Yan Lie agreed happily without any unnecessary nonsense.

This made Xu Tui's heart move slightly, and it felt a little warm.

Under normal circumstances, he and Yan Lie would have started the second wave of killing by now.

However, Yan Lie has been on alert for almost three hours without any complaints.

This teammate is really good.

The next moment, Xu Tui took out the transparent spiritual power source crystal he got from Xia Mira.

Both pieces are very small, less than one gram.

Xu Tui suspected that Xia Mira was also a stingy person. At first, she pretended to be generous and let him choose the source crystals at will. However, none of the source crystals that were given to Xu Tui to choose were more than one gram.

At this time, Xu Tui just cursed.

Afterwards, Xu Tui took out a small mental power source crystal and began to absorb it again.

Xu Hui kept experimenting for more than an hour, and his mental strength was also exhausted a little.

Just one second after it started to be absorbed, Xu Tui felt his head swelled and his energy was full!

Helpless, Xu Tui channeled the remaining energy to the eighth genetic point of mental whipping through the method of concentration.

Begin to strengthen the eighth gene base point of mental power whipping.

Previously, the Source Energy Strengthening Directional Mutation Potion was used for mental power whipping. There are nine gene base points for mental power whipping, and seven gene base points have been strengthened to level two silver.

There are still two gene base points missing. All the gene base points in this gene ability chain can be strengthened to level 2 silver by using mental power.

Xu Tui expected that his mental strength would be greatly improved by then.

I didn't have time before, so I just need to spare a piece of mental power source crystal and use mental power energy to strengthen the genetic base points related to mental power. The effect is the best.

As soon as the absorption begins, the seventh gene base point of mental power begins to expand rapidly.

Yan Lie, who was standing vigilantly not far from Xu Tui, faintly sensed the fluctuations of energy coming from Xu Tui's body.

Sweating a little.

Why did you start practicing again?

Practicing in this source energy super surge combat circle, to be honest, this is the first time Yan Lie has seen such a bold person.

If several people attack at the same time, it will be a big trouble.

Fortunately, the source energy super surge combat circle is full of source energy, and the energy aura is extremely chaotic.

If you are a little further away, you will not be able to sense or sense the energy fluctuations on Xu Tui's body.

It is impossible to tell that Xu Tui is practicing.

In addition, with the previous deterrent, it is not too dangerous.

But Yan Lie didn't dare to be careless in the slightest. He sensed the energy field and was on alert with all his concentration.

As soon as there is any trouble, we do not want to kill the enemy immediately, but we must warn Xu Tui as soon as possible.

Time passed very quickly, twenty minutes passed in the blink of an eye, and Xu Tui held back the transparent spiritual power source crystal in his hand.

It has become pure transparency.

It was said to be transparent before, but it actually has a slight milky color.

Now that the energy inside has been absorbed by Xu Tui, it has become transparent to the point of being almost glass.

Under the illusory inner view, the eighth gene base point of the mental whipping gene ability chain has been successfully strengthened to level two silver.

What is certain is that Xu Tui's two mental whip abilities, the mental hammer and the mental shock whip, must have been improved, and even his mental power has been slightly improved.

However, Xu Tui no longer had time to delve into these details.

Immediately, Xu Tui, who quit the meditation, threw the waste spiritual energy source crystal in his hand, which was only the size of a fingernail and had been emptied, to the ground in front of him.

On the ground in front, there is a source of energy falling from high in the sky.

Then, the mental induction unfolded and I began to carefully observe its changes.

A second later, Xu Tui's heart twitched violently!

Start recharging!

The source energy began to recharge this empty spiritual energy source crystal.

It's just that the speed is a little slow.

After trying so many times, this time, I finally got it right!

If the waste source crystal is to be recharged with source energy within a certain concentration, it must be the spiritual power source crystal in the condensed source crystal.

Currently, among Xu Tui’s experiments, this is the only one!

In an instant, Xu Tui thought of a lot!

He discovered this by a very coincidence.

I sprinkled the waste source crystal powder and cast butterflies flying all over the place, but I didn't expect to find that the waste source crystal powder was filled with source energy here!

After many tests, it was finally discovered that waste mental energy source crystals can be recharged with source energy here!
