As one of the five alliances of the Eternal City, the Black Tower covers an area of 1,000 meters, and the nine-story tower towers directly into the sky.

In God's Space, new experimental settings have replaced the equipment on the coast of the Eastern Continent, which Leo generated in the Black Tower Laboratory.

Leo, dressed in a black robe, stood in front of the device, looking at the instrument in front of him with a serious expression, and the gray liquid inside wrapped a biological arm.

Although the gray liquid in the instrument was wrapped in metal, the two were distinct, and just as the liquid wrapped the whole arm, Leo took out the test tube that had been prepared a long time ago and put the black and red liquid inside.

The black-red liquid was like a catalyst, and the gray liquid turned into countless tiny insects, burrowing through the pores on his arm, and Leo dodged to a secret machine.

The gray liquid in the instrument is pervasive, burrowing into the muscles along the pores, and begins to wrap the cells, blood vessels, and bones.

Gray liquid is a kind of molten metal, which is a kind of liquid developed and blended by Leo in combination with newly learned knowledge, this molten metal has a very high combination of magic factors, and can be perfectly fused with muscle tissue, so that the flesh and blood tissue has the characteristics of metal, and can continue to absorb related factors to strengthen itself.

Mechanical puppets and flesh puppets have their own flaws, materials, drawings, and production methods determine the level of mechanical puppets, and they also need a power source for output, and the growth space is very limited.

The growth of the flesh golem depends on the main material at the beginning of the production, this material is extremely rare, this is not something that Leo can get his hands on at this stage, and in the process of growth, he must devour high-level flesh and blood to evolve.

From the beginning of Leo's acquisition of the two kinds of knowledge, he always had an idea, that is, the refined puppets could be strengthened on their own and could cope with various complex environments, so he always wanted to combine the two kinds of puppets to refine the puppets in his mind.

The gray liquid had completely entered the creature's arms, and the original brown skin had turned gray, and a metallic sheen flowed through it.

Leo carefully took out his arm, he tried it with his knife, and when the small sound sounded, the sharp tip of the knife could not cut through the skin on it.

The small tissues in the arm of the explorer have lost their former activity, which is completely different from the irregular movement in the past, which is not in line with Leo's original intention.

"Is it because the molten metal is too much in the arm but it is inactive, or is the cell too fragile, or is the liquid itself inactive?"

Leo habitually wrote down the problems in his notebook and the next steps to be taken.

"Restoration. With a soft drink, the arms and liquids disappeared and were replaced by various primitive materials, "It would be nice if the memory metal hadn't been destroyed, so that we could try to see if we could refine the kind of robot from the movies in my previous life." Leo sighed and began to reformulate the gray liquid.

This time, Leo added the 'Tree Cockroach Juice' with an active effect to the liquid, which was taken from the low-level magical creature Multi-Eyed Cockroach, which is a variant of the cockroach infected by a magical creature, whether it is a severed head or a broken corpse, as long as the regeneration liquid used as the center is not destroyed, it can be restored to its original appearance after a while.

The gray molten metal was quickly prepared, and Leo generated an arm again, and was stunned just as he was about to repeat the experiment just now, "The most important thing for a puppet is his growth in addition to control, so why don't I use Rogge as an experimental subject?"

Do what you want, a living Rogge was born by him, this Rogge is the Modier Shafi who he dissected, and at first glance he looks like a magical creature with no soul, no mind, only a body.

Rogge was placed in a one-man tall glass cabin, and Leo once again generated a huge amount of molten metal, enough to refine an hourglass before he could refine enough liquid to envelop the entire Rogge.

The gray liquid began to pour into the glass chamber, and Rogge suspended in the middle as the liquid filled, and the difference between the two was as clear as before, and when Leo poured in the catalyst, the liquid began to burrow into Rogge's body.

Rog's facial muscles in the fluid began to contort, her limbs began to twitch, and the intense pain caused her body to react despite her lack of thinking.

As the minutes passed, Leo stared at the explorer with a focused expression, his spiritual power continued to be input through his hands, and the small gray insects on the lenses began to merge into the cells.

In this world, due to the magic factor, the composition of the cells is somewhat different from the previous life, and its colors are varied, and the number of colors determines the affinity of the magic factor.

In previous lives, cells were composed of nucleus, organelles, membranes, cytoplasm, and cell walls, but here cells are defined according to the structure of living organisms, limb cells, hair cells, blood cells, .......

Cells are the smallest unit of each living being, they contain the information code of the subject, and the most basic requirement for a wizard majoring in curses is to be proficient in cytology.

They will analyze the tissue with the most components in the cell, eliminate the means of conflict with it, and reach a specific part of the body that harms the cursed.

For example, if the limb cell is red, then the wizard will remove the conflicting materials such as the water system, and use his own means, or witchcraft, or rituals, etc., to cause the cursed person's limbs to be destroyed, uncontrolled, cannibalized, and so on.

Leo had studied the cytology of the world, and the idea of this world caused a serious conflict in the body of knowledge, according to what he learned, each cell should contain all the information characteristics of the subject, that is, all the genetic code of the organism.

Leo didn't study cytology in his previous life, but he still knew some basic common sense, and when he prepared liquids here, he prepared them according to some things in his previous life.

Cells themselves are learning, plastic, and evolutionary, and Leo wants to perfectly combine mechanical puppets and flesh golems, and there is a problem in this that is the serious conflict between living and non-living organisms.

This conflict is like a natural barrier, and Leo can't solve this barrier, so he wants to cultivate flesh cells to be metallic, so that such cells can evolve to achieve the desired result.

The whimsical experiment with Rogge was that he thought of Rogge's ability to strengthen himself, and if he could really do it, then the Rog family's method of strengthening himself should be equally effective.

The idea is very good, it is really difficult to make, Rog either dies after absorbing the liquid, or his whole body hardens and he can't even walk, Leo changes one method after another, but it doesn't achieve the result he expected.

The method of preparing the liquid was also changed by him...... over and over again.
