During this time, Lin Chen was teaching the scientific and technological knowledge collected on the Golden Crow No. 6 to Bi Yuwei little by little.

This little girl has been activated by the Book of Truth to reorganize the material, which is already very different from ordinary people.

In order to facilitate the calculation of the level, Lin Chen directly moved the hierarchy system from the other world. Now Bi Yuwei has just had her own exclusive skills, which is equivalent to a level 1 alchemist or knight.

However, unlike Lin Chen, Bi Yuwei's awakening is more similar to a warlock from another world, or it is more appropriate to count it as an ability.

When Bi Yuwei exerts this ability, she does not need to consume gold, but purely relies on her own spiritual power to change the structure of matter.

With the current state of Biyuwei's first level, the time for each cast is no more than ten seconds. Once it is too long, it can cause severe headaches. This is the damage caused by a short-term overdraft of mental power.

But don't underestimate these ten seconds, in these short ten seconds, Bi Yuwei is like a creator, able to transform the material structure out of thin air.

For example, now, under the guidance of Lin Chen, Bi Yuwei is reorganizing, repairing and even changing some complex metal parts.

It can be said that Bi Yuwei's ability manifestation is very similar to Bi Yuwei's repair ability. It's just that Lin Chen's ability is a fixed spell, while Biyu Weide is an ability, which is not only more flexible but also has more room for growth.

And now Lin Chen is designing a special device with Bi Yuwei.

"Lin Chen, it's done, look!" Bi Yuwei followed the method taught by Lin Chen, and finally processed a precision gear.

Taking the gear in Bi Yuwei's hand, Lin Chen took a closer look, touched Bi Yuwei's head happily and said, "It's great, it's very good." ”

After receiving Lin Chen's praise, Bi Yuwei blushed rarely. I saw her raise the cardboard in her hand, and a line of words immediately appeared on it: "Thank you!" ”

"Okay, don't be proud, I need you to build a device now, one that can generate high pressure, high heat, and at the same time be able to contain purifying bacteria and automatically absorb spore gases。。。。。。。。。"

Lin Chen talked to Bi Yuwei for most of the day, and almost fainted the little girl.

If Lin Chen's alchemy ability was still there, making such a simple device could be said to be handy, but now he could not have that ability.

So he needed a helper who was proficient in mechanical engineering to help him develop together.

And Biyuwei's little girl also lived up to expectations, and after listening to Lin Chen's request, she discussed the design details of the machine with Lin Chen.

The two completed the original design in a short time, and then began to use the existing parts to transform through Biyuwei's material restructuring ability, and then completed the assembly by hand.

If it was someone who was proficient in mechanical manufacturing, it would definitely be disdainful to see the two of them actually use these scrapped parts to manually assemble a precision machine.

After all, if you want to make a precision machine, all the parts on it need to be designed and manufactured individually. It's not that you can't manufacture those generic parts when you use them, but you can't control them in terms of accuracy and volume.

But with Bi Yuwei's material restructuring ability, none of this is a problem. If the part is too large, it will be directly ground to become smaller, and then the ability to be fine-tuned will be used to store the same level of accuracy as the industrial mother bed.

If it weren't for the fact that the little girl's mental power is limited now and she can't go deep into the atomic level to control it, maybe she can directly build this machine out of thin air.

It took about half a day for Lin Chen and Bi Yuwei to finally create a barrel-shaped object similar to a boiling water bottle.

Lin Chen named it Spore Purifier 1. 0。

However, as an initial design, after some inspection, Lin Chen found that there was still room for further improvement.

So I tinkered with Biyuwei for a long time.

The internal mechanical structure has been re-optimized. Then brand new spore purifier 2. 0 freshly baked.

I completed an invention by myself, and the little girl was very excited.

It was a sense of accomplishment.

I saw Bi Yuwei pick up the spore purifier and happily send it to Lin Chen.

"Good, great!"

Lin Chen just scanned it with his detection skill and knew about this spore purifier 2. Version 0 has already met his requirements.

Bi Yuwei's material restructuring ability was even better than he thought.

In this world where human beings have lost the ability of precision machining, Bi Yuwei alone is equivalent to a super precision machining center.

As long as she has enough knowledge and blueprints, maybe this little girl can rely on a hammer to knock out a Star Destroyer!

Although things are made, the energy supply is a big problem.

In this day and age, most batteries have either failed due to corrosion of spores, or have been left for too long and their internal structure has been damaged.

And because of the fault line in civilization, human beings have long been unable to manufacture high-energy batteries.

So he had to use his repair ability to repair these long-damaged batteries one by one.

And because these batteries have been failing for so long, the repair is complicated, and a high-energy battery that can drive a spore purifier requires twenty gold points to repair.

Although Bi Yuwei could also do this kind of repair work, Lin Chen needed the little girl to help him make a spore purifier instead of using his precious spiritual power to repair the battery.

So this hard work fell on Lin Chen's head again.

Look at the golden points in your hands that are less than three digits. Lin Chen sighed heavily.

Originally, Lin Chen still had 650 points in his hands, but recently he had explored groundwater and had some other repair actions, and after some operations, there were less than 300 points left.

A battery of 20 points, 300 points can only repair 15 high-energy batteries. That's a lot of people, what can you do!

"I'm going to collect gold again, when will I not worry about it?"

As soon as he thought of the problem of money, Lin Chen had a headache!

It was at this time that the door of truth popped up.

"Lao Lin, why are you getting more and more unkind to you, do you want to starve me to death? Hurry up and gather people to fight, as soon as the cannon goes off, there will be ten thousand taels of gold. We robbed the Lord's Mansion of the Western District first, and then looted the Eastern, Southern, and Northern Districts, and made a good windfall! ”

Hearing the noisy voice of McDonald's, Lin Chen couldn't help but be angry!

Where Lao Tzu is worried, this product will only be shouting everywhere, and he has the ability to come by himself.

"Shut up, McDonald's!"

"You and I don't want to make a windfall, now we don't have a few people in our hands, we don't have a few guns, you still want to uncover the rod, be careful that you can't recover!"

"Now we need to make a fortune in silence, and low-key is king!"

Hearing Lin Chen's words, the Gate of Truth was not happy.

"Lao Lin, don't make trouble, are you such a low-key person? When we were in another world, we punched the goddess and kicked the demon, but we never saw you so modest! ”

was exposed, and Lin Chen couldn't help but blush.

His own family affairs, at that time, he was a peak tenth-level alchemist, the supreme master of the alchemy kingdom, and the puppet army under his command was millions. Seeing who scolds whom, it can be said that life and death are bearish, and if you don't accept it, you will do it.

Now that I'm in this situation, it's basically equivalent to a semi-crippled state, and if I really want to play like this, I guess I'll be the first to be killed.

Build a high wall and slowly become king. After all, he is also a person who has managed an empire, and Lin Chen still has this bit of self-knowledge.

Thinking of this, Lin Chen said to Bi Yuwei: "Girl, I'll leave it to you here, I'll find you a few more people, and you can make a spore purifier 2 with peace of mind." Version 0, as for the battery, I'll take care of it! ”

"Uh-huh!"

Bi Yuwei obediently answered and agreed.

"Good!" Seeing Bi Yuwei's obedient appearance, Lin Chen touched the little girl's head with satisfaction. For an obedient and well-behaved and particularly capable child like a little girl, Lin Chen likes it quite a lot.

Cute and capable, it's really satisfying!

And Bi Yuwei also enjoyed Lin Chen's touch very much.

After awakening the material restructuring ability, Bi Yuwei liked to stay by Lin Chen's side very much, and Lin Chen's big hand stroked her all over her body.

This is actually the interaction between the door of truth and the projection. After all, the little girl's ability comes from the projection of the Door of Truth. But projection is an illusory thing after all, just like there is no shadow without light.

That feeling is like recharging.

And every time Lin Chen stroked Bi Yuwei's head, Bi Yuwei could feel bursts of warm sun-like sensations radiating all over her body, gradually improving her physical fitness, making her warm all over. And with that, Bi Yuwei's ability level is slowly increasing.

After enjoying Lin Chen's caress for a while, Bi Yuwei, who was fully charged, immediately threw herself into the manufacturing of spore purifiers with great interest.

Lin Chen, on the other hand, summoned all the scavengers to collect more high-energy batteries and gold ornaments.
