Lu Yunze flew over Tianxing City in a good mood. The matter on Fantasy Moon Island has come to an end. The remaining three elixir monks Lu Yunze did not take their lives, but handed them over to Ling Yuling.

According to Ling Yuling, for him, living people are more useful than dead people.

Lu Yunze is not a natural murderer, so he simply gave everyone to him.

After saying goodbye to the three brothers and sisters of Biruxi, Lu Yunze embarked on a journey back to Tianxing City.

Now that everything has been resolved, the giant city in front of him is getting closer and closer, Lu Yunze can't help but remember his next plan.

First of all, the Eye of the Sky series must be improved as soon as possible, and at least it must be worthy of the Nascent Soul-level efforts.

It is almost enough to not ask that it can really threaten the life of the Nascent Soul monk.

Another thing is the invisible escape technique passed down by Qiong Wuji. To be honest, relying on the bonus of "Five Elements Escape Art" and his own talent, Lu Yunze has not put too much effort into this before, but now after he really fought a few Dan-killing cultivators once, Lu Yunze realized that his attainment in invisible escape technique was really not good.

Not to mention anything else, if his invisible escape technique can have the seventh level of fire in the Qiong Wuji, he will not use the Eye of the Heaven to deal with those cultivators of the elixir.

After returning this time, he said that he would practice the invisible escape technique that would be hard for a period of time, at least he would not fall into the reputation of Qiong Wuji.

Finally, it is the invisible magic weapon he has been thinking about before!

Lu Yunze touched his eyebrows, and the corners of his mouth gradually raised an excited curve.

Not long ago, Lu Yunze was still struggling with what his ideal invisible needle should be like.

He made more than a dozen completely different plans for this. It can be said that each plan is the master of his current weapon refining skills. Once released, it will be enough to make a group of high-level monks beat their heads to death. Even some large sect forces may not be able to resist the battle.

That's it, Lu Yunze is still not satisfied.

Although each of these invisible needles is a superb magic weapon that is extremely powerful, none of them is in line with Lu Yunze's wishes. But this dead Jiao Lao is a little obsessive-compulsive in this regard, and almost torture himself to death.

Until he realized the existence of the inner demon!

What should an invisible needle look like?

Lu Yunze's most ideal view on this is that it is invisible, material, shadowless, and cannot be captured by spiritual consciousness, and cannot be imprisoned by magic power. It can change with the help of the heart.

Originally, this was just an ideal goal, and Lu Yunze didn't even expect that he could do such an outrageous thing.

But after he studied the existence of the inner demon in depth, Lu Yunze suddenly discovered that this thing completely meets all his requirements for the invisible needle!

In-depth study of the existence of the inner demon is undoubtedly a profound topic that will not have any results in a short period of time. But what if you find a way to treat the inner demon as a certain refining material and refine it into part of an invisible needle?

It sounds quite confusing!

Lu Yunze also had some ideas about how to use the inner demon as a refining material.

What he needs now is a lot of practical operations, but before that, Lu Yunze must deal with a fatal matter first.

He is almost gone for spirit stones!

The Eye of the Sky series is much more expensive than he imagined. You should know that although the puppet is driven by the spiritual consciousness of a monk, to put it bluntly, it just uses the spiritual consciousness to connect with the puppets to let them rigidly execute some monk's commands. Ordinary attack defense is OK. If they want to create a profound thing like formation, the first thing they need to solve is the problem of the monk himself.

Formation cannot be done by simply using simple actions such as stance and effort.

This involves every subtle movement of each puppet, and must be coordinated closely. If a little mistake is made, the formation will collapse directly.

So if you want to set up the formation with one person's strength, you need to be distracted at least a dozen places, make completely different reactions at the same time, and cooperate closely.

This difficulty is not a pediatric department like drawing a circle with a left hand and a right hand. If you really want to play like this, Lu Yunze must first turn himself into schizophrenia, and he must also be an outrageous patient who splits into more than a dozen different personalities.

Although Lu Yunze knew that he was not a normal person, it was still too exciting to turn himself into schizophrenia and he couldn't play with it.

So Lu Yunze thought of a trick. He referred to some sets of magic weapons and special applications of formation tools, and finally came up with the idea of ​​dividing the prepared array diagram into twelve pieces in advance and engraving them inside the twelve Eyes of the Sky.

It is equivalent to programming in previous life. First enter the pre-edited program and press the switch when needed to use it to make the program run by itself.

After completion, the twelve Eyes of the Sky became a magical existence with both characteristics of puppets and formation tools.

Choosing this spherical body is also a helpless move under this design. Only in this way can there be enough internal space for Lu Yunze to use it to engrave the array diagram.

So far, this method has no major disadvantages, the only problem is that it is costing!

After scrapping seven or eight sets of Eyes of the Sky, Lu Yunze barely made such a practical finished product.

The materials he had also consumed in this process, and it was not enough to perfect the remaining materials for him to improve the Eye of the Sky.

In addition, this set of things has not been completely perfected because the internal spiritual power transmission facilities are not completely perfect, and the consumption of spirit stones is also quite terrifying when it is barely operated.

Inside each Eye of the Sky, Lu Yunze has left a set of energy supply facilities of the same style as the Five Elements Belt, which are inlaid with five intermediate spirit stones for energy supply.

Not long ago, after the entire set of Eyes of the Sky was put into the formation, all the spirit stones were consumed in just a short while.

There are five intermediate-level spirit stones in one Eye of the Sky, a total of twelve, that is, sixty intermediate-level spirit stones.

Just in just a short while, Lu Yunze threw away six thousand spirit stones!

Although it is not unaffordable for Lu Yunze's wealth, it does not prevent Lu Yunze from feeling hurt!

Seeing that the method of refining invisible needles was another bottomless pit project, Lu Yunze couldn't help but look a little dark. He suddenly realized that there were not many spirit stones on his hand, at least not enough for him.

He had to find a way to get some spirit stones, and at least he needed to support him in completing several experiments at hand.

When Lu Yunze thought about this, his mood suddenly became a little heavy.
Chapter completed!
