On a temporary research platform, lying a huge stone-shaped elemental creature, which is a variant of the earth element. But at this time, the body of this elemental creature was shining with a strong arcane light.

The arcane light oscillated and penetrated continuously. Finally, when the light reaches a critical point, it completely blends into one.

The distance on that elemental creature shook, and after a long time, the whole body became a spot of light and disappeared.

"I still haven't figured it out. Now there are only two difficulties that can be completely solved."

Jiang Hen recalled his research, the two biggest difficulties. One of them is the variation of elements, which means that this is not a single elemental power, nor is it a common way of using elemental power.

It must be mutated, and my understanding of this aspect is still somewhat insufficient.

This is mainly because one's own level is not enough, otherwise, the research will be very fast. But Jiang Hen was not worried, because his progress in this area was improving.

In other words, within one or two years at most, you can study it clearly.

And this time, the most on the other side of the earth is one or two days, which is nothing at all.

But there is another problem, that is troublesome. Because elemental creatures have their own thinking, Jiang Hen discovered that it is this kind of thinking that can control the entire body of elemental creatures.

And his rock puppet has no thinking at all, but just a fighting instinct.

The rock puppet can only act on the command of the master, otherwise, it is instinctively attacking some people who attacked him. And without thinking, there will be no spiritual power.

Without mental power, when the elemental power reaches a certain height, it is difficult to control.

In other words, one's own skills, reaching Tier 4 is the limit, this is already a miracle. If you want to continue to improve, it is simply impossible.

This is not a magic puppet, it is just a pure energy bondage.

If you can solve this problem, you will truly have the ability to fight the puppet master in number.

But at this point, Jiang Hen has made no progress at all.

Almost instinctively, Jiang Hen used the rock puppet core against a stone to create a stone warrior.

"Where is the problem? What should I do? Is it necessary to study the undead spells? Their research on the soul is the most powerful." Jiang Hen said to himself.

It's just that Capital University belongs to the orthodox college and is not good at this type of undead.

There is no way, to study these types of spells, you have to do some very evil experiments. In this regard, Capital University is strictly controlled, and there is no way to go further.

The colleges that are good at this are not even in the capital.

From the remaining knowledge, Jiang Hen knew what the foundation of those undead creatures was. First of all, some corpses after death, and then some memories and soul breath left on the corpses.

Fuse these things into a virtual soul, so that you can summon.

"Wait, the remaining memory and soul breath, this thing, even if it is not a necromancer, it seems that it can be mobilized."

Jiang Hen's eyes lit up suddenly, as if thinking of something. "How are the high-level undead creatures made? I remember that it seems that the soul needs to be used directly, or just soul fragments."

"Even they will cruelly punish creatures for some special undead, so as to obtain more special mutant souls. But I remember there is a saying, it seems that undead creatures are not the same as before."

Jiang Hen thought about it for a while, and it seemed to be a relatively well-known research report.

Specifically, although undead creatures have memories of their lives, they are all things that are kept for the undead to exert their strength. They are only memories, and the undead actually no longer existed before their lives.

Even if everything is known, it seems to be the same, but it is actually not the case.

Because undead creatures basically do not use the soul of the original creature to drive, most of them are soul fragments, plus some original memories, and some people may even construct false memories to integrate them.

The purpose of everything is just to allow the undead to exert their strength.

Those things seem to be a kind of knowledge to undead creatures. If anyone regards him as the person before his death, that is definitely a very dangerous thing.

"Soul fragments and memories, I know."

Jiang Hen patted his head, why he hadn't thought of this long ago.

For a long time, when I made rock puppets, I used magic core fragments. That is, a complete magic core, cut it apart, so that you can maximize the number of puppets you can create.

This method can save materials, but it is inherently problematic.

The magic core is the most important core of a Warcraft itself. In fact, this thing itself contains the spirit of Warcraft, and even soul fragments. Some powerful monsters can incorporate the entire soul into them.

But once the magic core is destroyed, the soul aura inside will disappear without a trace.

"In other words, I can actually use a complete magic core to make it. This problem can be solved long ago."

Jiang Hen was speechless for a while, knowing why he was struggling to divide the magic core.

The original division was to save materials on the one hand, and to eliminate the problem of attributes on the other hand. Because the magic core itself has different attributes, after being cut, some of the magic residue originally contained can also be cleaned up Without the attributes, Jiang Hen can use any magic core fragments to make what she wants. .

"So, if you use a complete crystal core, you have to modify its properties, otherwise you really can't make it."

A problem was solved, and then a new problem appeared.

The most important thing is to modify the memory inside. Beasts and puppets are not the same type. Maintaining the instinct of that kind of beast, it is strange that this puppet can exert its power.

Therefore, it is necessary to find ways to modify memory and incorporate something that can exert its own power.

But I still don't have enough knowledge in this area. Thinking of this, Jiang Hen felt depressed for a while.

"It seems that I need to go back to school to study first. Fortunately, the cooling time of this secret realm orb is very short, and this time just can learn a lot." Thinking of this, Jiang Hen wanted to activate the secret realm orb and directly returned home.

He just appeared, and there was no other nonsense, so he went straight to the library. Now he needs a lot of knowledge system.
