"The loss is so large...... Zheng Yichen looked at the soul ball in his hand that was less than half of the original volume, and couldn't help muttering, purifying and eliminating not only negative energy, but also a part of the soul power, after all, the connection between the two is too close, Zheng Yichen must have additional loss when he tosses so much.

However, without the infiltration of negative energy, the remaining soul quality has been greatly increased, but the quantity cannot meet Zheng Yichen's needs, and it can be further 'purified' with continued efforts, in this case, Zheng Yichen glanced at the soul stored in the frost sorrow...... Rub, how can there be so many more souls in this meeting? Could it be that there is a war somewhere?

Scratching his head, this world is not peaceful, there are wars or something from time to time, for example, today this small country fought that small country, this country hammered another country, and the scale of the war ranged from hundreds to thousands or even tens of thousands.

Think about it, if this sword appears in such a battlefield, how many souls can it directly harvest?

Extracting a part of the soul from it, Zheng Yichen dispersed the frost sorrow that was summoned, although the soul inside was accumulating, it did not reach the level of massiveness, and taking too much at one time would reduce the power of this sword.

After rubbing the pill for a period of time again, Zheng Yichen stared at the final product in the palm of his hand, and after many times of purification, the color of this compressed soul ball was close to translucent white, and of course there was still a part of the gray in it that could not be removed.

This is already the limit of what Zheng Yichen can do now, and if he wants to further squeeze out the negative energy contained in it, Zheng Yichen feels that his strength has to be more than doubled before he can do it.

"Hey, that's enough. Zheng Yichen scratched his head and showed an inexplicably weird expression, he used so many souls at one time, and now that he thinks about it, he is also sick enough...... Tsk, forget it, it's not a conscious soul anyway, it's all a resentful spirit, so it's okay to use it...... The conscious soul wasn't just released by itself.

This is a compressed soul...... Zheng Yichen estimated that he would probably be able to make five to eight alchemy puppet intelligence cores, or else make a set of rose girls by himself?

Touched the tip of his nose, uh, this is better to find a higher quality soul in the future, this one in his hand is compressed and purified, although the quality is good, but it can only be said that it is medium, and there is still a distance from the high-quality one.

Making with this kind of 'material' that is not good is inevitably a waste of 'creativity', and good ideas should of course be kept until the most suitable materials or conditions are available.

"Hmm...... Mass-produced alchemy puppet ...... Okay! That's it!"Alchemy puppets, out of the kind of flesh puppets, mud puppets, granite, iron lumps and the like, the puppets made by alchemy and engineering can be understood as otherworldly robots.

And among the robots with humanoid appearance, what can have the T series Terminator classics? Although a group of big men are a little out of line with their own aesthetics, but there is no better reference option at the moment, so you can't make a batch of them in your own image, so Zheng Yichen feels that it will be even more strange, and every day he looks at the mechanical puppets that are exactly the same as his own before the crossing, which is a bit unacceptable.

Therefore, the alchemy puppet of his own image is still used by himself.

Regarding the production of alchemy puppets, although the preparation core is the most important part, there are still other aspects that need to be treated seriously, such as...... The design of the alchemy golem.

Zheng Yichen consulted and recorded the design drawings from the library, but the knowledge of the other world and the world before the time travel are different, because of the extremely convenient power of magic, many structures in the design drawings seem a little ...... Contradictions, at least that's what Zheng Yichen seems.

This is also based on the very convenient power of magic! How convenient? Is it convenient enough to make a skeleton move? If you use the power of science, you don't know how many extra parts you have to load on it, and what is more convenient is not limited to skeletons, carving out a puppet, you can use magic to temporarily 'animate' it.

Even for this reason, there are many places in the design drawings of engineering in this world that do not seem to be sophisticated, but the reason why it can be kept secret is because it involves the core system of magic, and although the structure of the design is simple, it can only work properly with related magic.

In short, for such a design drawing, Zheng Yichen said that he couldn't bear it at all, he really relied too much on the power of magic, obviously as long as he improved it slightly, driven by the same magic power, he could exert a greater effect, and he only paid some time for modification, so why retreat and choose a worse one?

Since it is to be overhauled, the skeleton must be the first to be improved, after all, the skeleton is the most important support for the alchemy puppet, and it is also the thing that limits the range of activity of the alchemy puppet to the greatest extent, since it is to be humanoid, of course, it must be done according to the humanoid skeleton, but it can't be exactly the same.

For example, in terms of the head, the maximum range of human twisting is 90 degrees to the left and right, and it is 180 degrees directly...... There are slightly fewer people who can do this...... What can be done is basically scared to death at some moments.

The alchemy golem can remove such a restriction, which helps to quickly observe the surrounding situation, in addition to the twisting range of the arms and wrists, etc., can be adjusted to achieve a more efficient use of limbs.

This time the design is different from the sloppy mechanical dragon, Zheng Yichen took two days to re-modify and improve the original design drawing, as long as the framework is good, then even if there are some flaws, it can be ignored under the power of magic, and Zheng Yichen is now striving for perfection, and has achieved the degree that he can't further modify and improve now.

After these alchemy puppets are made, they can take into account a certain amount of combat effectiveness at the same time, and they can also carry out some more delicate work, the latter is what Zheng Yichen needs most now, he needs some 'assistants' who can do assembly line work, if the alchemy puppets are too clumsy, then there is no meaning, at least without Zheng Yichen's modification, the alchemy puppets on the design drawings are basically like little giants after they are made...... What delicate work can be expected of those turnip-like fingers?

Work on the job...... Let's plant sweet potatoes in the field!

With some selfish motives, Zheng Yichen first made an alchemy puppet that referred to his own image, and let the simple and old-style alchemy puppet he used to use be well modified and completely perfected.

"It feels pretty good...... "I tried to control this alchemy puppet that has not yet been covered with camouflage skin, the degree of flexibility is far greater than the previous one, and the power exerted is also several times that of the original, this is already a leapfrog improvement, so let's leave it at that.
