"Well... this black technology in another world." In the underground library of the castle, the mini dragon kept flipping thicker books that were more than it was, muttering from time to time. Next to him, a ghost maid was bored playing with a bamboo dragonfly. When he was in the house, Zheng Yichen kept all the guts he made. Now those guts have become the spoils of the ghost maids.

Even some ghost maids who are idle and have nothing to do will play with. This is how it greatly alleviates the indifferences of these ghost maids, allowing Zheng Yichen to read books here safely now...

He is now watching about alchemy puppets. Well, this thing is not separated from engineering credits. Engineering provides a skeleton and alchemy fills it. Now he is watching the fill part. The real alchemy puppets have a certain degree of "intelligence". They can independently complete some instructions from their makers, and can continue to run as long as the magic power is enough.

There is no so-called computer in this world, so this "intelligence" needs to be replaced by something else... The thing that needs is the soul!

The soul required is not limited to only humans, and the use is not to fill this soul into the alchemy puppet. Instead, the soul is used as a material to make the intelligent core of the alchemy puppet. After it is made into the core, most of the characteristics of the soul will disappear, and only the most basic elements are retained.

After all, the soul field is very mysterious and difficult to operate. If the interference with the soul is a little mistake, it will cause damage or even collapse of the entire soul. The quality of the soul material that makes the core affects the core quality. The higher the core quality, the higher the intelligence level of the alchemy puppet will have.

With the improvement of the workshop, Zheng Yichen discovered that he was really short of manpower alone, and just taking care of it every day was a very troublesome thing, not to mention that the body had to run around every day to "exercise".

After a while, the ghost little maid on the side lost interest and turned her gaze to the alchemy book that Zheng Yichen was looking at. She tilted her head and bit a finger for a while, and gently tapped the back of Zheng Yichen's head.

"Well? You mean if you lack personnel, you can draw some maids?"

The ghost maid who expressed her meaning nodded with her little face and raised her chest, probably...'Choose me! Choose me quickly!'.

"Ah~ I don't need this. My current situation is not good. I can give up that workshop at any time. If you want to go, wouldn't it be harmful to you if something happens?" Zheng Yichen shook his head and refused. The face of the ghost maid in front of him immediately pulled down.

"Well, that's it all." After temporarily putting together this book, Zheng Yichen's projection body expanded to the same level as the original body. He reached out and grabbed the ghost maid and placed it on his back. "Let's go, in addition to checking the information this time, I'm also going to arrange some interesting things near the castle. By the way, are there anyone among your sisters who master alchemy?"

The little ghost maid thought about it and shook her head very simply. This answer made Zheng Yichen a little stunned. What the hell? Didn’t there be any one? After getting involved in alchemy and engineering, Zheng Yichen felt that the knowledge of the law profession in mastering the relevant use of the law profession is that it has innate advantages, so there are always one or two of the more than 20 magic ghost maids?

"It's really not one?"

The little ghost maid nodded seriously and waved her hand to gesture. The more she looked at Zheng Yichen, the stranger her face became. "You think it's difficult to learn alchemy? Even if there are not many humans?"

Is it really difficult? Zheng Yichen has not found it difficult to learn and master since he came into contact with alchemy. Although there is indeed a lot of knowledge that is quite difficult to understand, it can be broken by studying and exploring it more. As for engineering, it is even simpler. "Well, what about engineering?"

The ghost maid continued to gesture, meaning that this was simpler, but engineering is complementary to alchemy. After missing one, it was equivalent to cutting off some of the development routes...

Zheng Yichen can understand this. To put it this way, if you master engineering, you can make the kind of steel armor that can be worn on yourself, similar to the equipment of Iron Man. People can also move and improve combat power while wearing it, but most of them will increase defense and attack power.

However, if alchemy is added, the performance of this armor can achieve a qualitative leap, such as correcting the accuracy of the attack, assisting aiming during long-range attacks, analyzing enemy attacks, etc. These are all things that cannot be achieved by a single engineering. After developing to a sufficient level, it is the difference between the performance of mecha and EVA.

"This is a bit troublesome." Zheng Yichen scratched his head. The location of the castle had been changed. The whole process had no momentum, just was carried out silently. As for the impact of the new environment on here, there was no such thing. These ghost maids were all senior homegirls. It was nothing, they just didn't even go out of the gate.

Without Zheng Yichen living here, they basically don’t need to eat. Apart from occasionally satisfying their desire to taste delicious food, they have no reason to go out.

Instead of letting them continue to have free time so bored, Zheng Yichen was preparing them to find something to do. When building the workshop, Zheng Yichen continued to conduct subsequent research on the monitor. In addition to still breaking through sound transmission, the clarity of the image has been greatly improved, and the secret has also increased a lot.

The principle of the monitor is to "see", not magic detection, it is enough to ensure the internal operation. Therefore, the magic-averse material can be selected in the shell. As for the transmission of "information" will be blocked by the abrasive material, Zheng Yichen has a solution to this, so I just need to pull an antenna outward?

As for the distance, if it is too far, it will indeed generate additional magic fluctuations, but each monitor is equivalent to a repeater. Under the premise of mutual connection, the magic fluctuations emitted will be suppressed to the lowest point. Yes, Zheng Yichen plans to create a monitoring network with the castle as the center. The plan will cover a large area, and the maintenance work required will follow. This is the matter of the ghost maids.

Lolis didn't care about the "neighbors" in the Magic Forest, but Zheng Yichen cared about it. Just look at the outfits of those people, he knew that they would definitely not be good people... It is a good thing to prepare for the future. No one helped to do this, so it took a lot of time to make Zheng Yichen do it alone. This made him wonder whether to slow down the arrangement of the surveillance network first and make the real alchemy puppets, not to ask how powerful they have, as long as they can assist in the assembly line processing of some materials.
