"Hmm...... This otherworldly black technology. In the underground library of the castle, the mini dragon has been flipping through thick books that are several times larger than its head, muttering from time to time, next to him, a ghost maid is bored playing with a bamboo dragonfly, when he is at home, Zheng Yichen left all the gadgets that were made, and now those gadgets have become the trophies of the ghost maids.

Even some ghost maids will play with them when they are idle, and that's it, which greatly alleviates the remnants of these ghost maids, so that Zheng Yichen can still read here safely......

What he's looking at now is about alchemy golems, well, this thing has nothing to do with engineering credits, engineering provides skeletons, and alchemy fills them, and now he's looking at the filled part, the real alchemy golems have a certain degree of 'intelligence', they can autonomously complete some of their maker's instructions, and as long as the magic is enough, they can continue to run.

There is no such thing as a computer in this world, so this 'intelligence' needs to be replaced by something else...... The thing that is needed is the soul!

The required soul is not limited to only people, and the use of this soul is not to fill the alchemy puppet, but to use the soul as a material to make the intelligent core belonging to the alchemy puppet, after being made into the core, most of the characteristics of the soul will disappear, and only the most basic elements will be retained.

After all, the realm of the soul is very mysterious and difficult to operate, interference with the soul, the slightest mistake will lead to the damage or even collapse of the entire soul, the quality of the soul material that makes the core affects the quality of the core, the higher the quality of the core, the higher the intelligence of the alchemy puppet will be.

With the improvement of the workshop, Zheng Yichen found that he was really short of manpower, and it was a particularly troublesome thing to take care of it every day, not to mention the 'exercise' that the body had to run around every day.

After the ghost maid on the side finished the bamboo dragonfly for a while, she lost any interest, and her eyes turned to the alchemy book that Zheng Yichen was looking at, she tilted her head and bit a finger to think for a while, and gently tapped the back of Zheng Yichen's head.

"Hmm, you're saying that if you don't have manpower, you can transfer some of the maids from the past?"

The little ghost maid who expressed her meaning nodded with a small face, and held her chest up, which probably meant ......'Choose me!

"Ah~ I don't need this, I'm not in a good situation now, that workshop can be given up at any time, let you go, if something happens, won't it hurt you?" Zheng Yichen shook his head and refused, and the face of the ghost little maid in front of him immediately fell.

"Ahem, that's it. Temporarily putting together the book, Zheng Yichen's projection body swelled to the same extent as the body, and reached out to grab the ghost little maid and put it on his back, "Let's go, in addition to checking the information when I come back this time, I am also going to arrange some interesting things near the castle, by the way, among your sisters, are there any who have mastered alchemy?"

The ghost maid thought about it for a while, and shook her head very simply, this answer made Zheng Yichen a little stunned, what the hell? Is there actually no one? After coming into contact with alchemy and engineering, Zheng Yichen felt that the legal profession has an innate advantage in mastering the knowledge related to use, so there are always one or two of the more than 20 legal ghost maids, right?

"Not a single one?"

The ghost maid nodded solemnly, waved her hand and gestured, the more Zheng Yichen looked at it, the more strange his face became, "You said alchemy is difficult to learn, even if there are not many of them?"

Is it really difficult? Zheng Yichen doesn't feel how difficult it is to learn and master from the time he came into contact with alchemy to the present, although there is indeed a lot of knowledge in it that is quite difficult to understand, but it can be overcome with more research and exploration, and as for engineering, it is even simpler, "Hmm, what about engineering?"

The ghost maid continued to make a comparison, meaning that this is simpler, but engineering and alchemy complement each other, and if one is missing, it is equivalent to cutting off part of the development route......

In this way, Zheng Yichen can understand, let's put it this way, if you just master engineering, you can make the kind of steel armor that can be put on your body, similar to Iron Man's equipment, and people can also move to improve their combat power when they wear it, but most of them are to enhance defense and attack power.

However, if you add alchemy to it, then the performance of this armor can be qualitatively improved, such as correcting the accuracy of attacks, assisting aiming when attacking from a distance, analyzing enemy attacks, and so on...... These are all unattainable by a single piece of engineering, and when developed to a sufficient height, it is the difference between the performance of the mecha and the EVA.

"That's a bit of a problem. Zheng Yichen scratched his head, the location of the castle has been transferred, and the whole process has no momentum, it is carried out in silence, as for the impact of the new environment on here, there is no such thing, these ghost maids are all senior house girls, nothing to do, but the gate is not out of the second door.

Without Zheng Yichen living here, they basically don't need to eat, except for occasionally satisfying their desire to taste food, they have no reason to go out.

Instead of letting them continue to be idle so boring, Zheng Yichen is preparing them to find something to do, when building the workshop, Zheng Yichen also continued to conduct follow-up research on the monitor, in addition to the sound transmission is still broken, the clarity of the image has improved a lot, and the degree of privacy has also increased a lot.

The principle of the monitor is 'look', not magic detection, as long as the internal operation is ensured, so the shell can choose the disgusting material, as for the transmission of 'information' will be blocked by the wear-averse material, Zheng Yichen has already had a way to solve it, isn't it okay to pull an antenna outward?

As for the distance, if it is too far, it will indeed produce additional mana fluctuations, but each monitor is equivalent to a repeater, and under the premise of connecting with each other, the magic fluctuations emitted will be suppressed to the lowest point, yes, Zheng Yichen plans to take the castle as the center and make a monitoring network, the scope covered by the plan will be very large, and the amount of maintenance work required will also follow, this is the matter of the ghost maids.

Loriss doesn't care about the 'neighbors' in the Forest of Illusions, but Zheng Yichen cares, looking at the outfits of those people, he knows that he will definitely not be a good person...... , It is a good thing to take precautions after all, no one to assist in doing this, and it is very time-consuming to let Zheng Yichen complete it alone, which makes him wonder if to slow down the arrangement of the monitoring network first, and make the real alchemy puppets, not asking how powerful they are, as long as they can assist themselves in the processing of some materials on the assembly line.

It takes time to make, and so does processing materials!
