This is the first time that Wang Fen has transformed items other than batteries, of course, he said that the star core is to be repaired rather than transformed, and the main purpose is to practice his hands and accumulate some experience for the future manufacture of food regeneration machines.

Since it is a practice, let's start with a simple and easy one, and the simplest place for this car is the two copycat car ears that cost hundreds of dollars.

There is a saying in the mountain city that describes a man lying on his stomach and listening to a woman's words, which is called "raking the ears".

Wang Fen also felt that he bought such a cheap and copycat car afterwards, and the ears were too picky, so the first thing he wanted to transform was it. The purpose of the transformation is to make the ears of the car no longer break when they are hit, and they are soft when they are broken. It is no longer a rake ear, but a super hard ear that is constantly slashed and cannot be bent by the car, so as to be worthy of the image of a masculine man like him.

Wang Fen didn't know how to modify the ears of the car, but he felt that it should be similar to the way to transform the battery, and he would only use this trick, so he held tightly with both hands the connection between the ears of a copycat car that had just been installed for less than two days and the car, of course, the star core was sandwiched between his hand and the rearview mirror.

Everything was ready, Wang Fen tried to knead the star core as hard as he did to transform the battery, and various tricks took turns, but the star core did not emit any fog at all.

"What's going on, there's no reaction at all. After five minutes, Wang Fen said uneasily, adding a few more handfuls of strength in his hand, and giving the star core a nine light and one deep, so that the color of the star core in his hand continued to change.

"We are analyzing the internal structure and material composition of the rearview mirror and how to reinforce it. The star core replied unhurriedly, Wang Fen pinched it so diligently, it was indifferent, it had time to take its time.

"I've pinched you for a long time, and you haven't started at all? You have to think about it for so long to reinforce the ears of such a simple car, your IQ is really anxious, and it is really lower than that of a primary school student. Wang Fen beat his chest and wailed. He was very anxious, thinking that he had already stepped directly into the topic, but he knew that after pinching for a long time, he was actually regarded as foreplay by the star core.

"Because of this reinforcement of the rearview mirror... Maintenance, does not involve energy, only physical reinforcement, and the main material is plastic is not a conductor, it is difficult to reinforce in a conventional way, if it is reinforced in the previous way, the time will be at least one day. "Star Core still calls the modification of the rearview mirror a repair, and compared to a day, these five minutes are completely negligible, so it doesn't feel wasted at all.

"It's just a car ear, how can it take a day. Wang Fen wailed in a low voice again, and in the middle of the night, he was alone outside the house with two wires tied to the ears of the car, what would he think if he was seen by others.

And if it takes so long for a rearview mirror to take so long, how long does it take to rebuild the whole car, how long does it take to make a food regenerator, and if it's so slow, then do you want to save the earth? What's more, if he uses the time to reinforce the ears of the car to transform the battery, he can buy a low-profile version of the car, so it seems that the cost performance of transforming the rearview mirror is too low.

"And how do you parse the material of the car ears, I don't see any movement at all, you won't fool me. Wang Fen continued to ask suspiciously, feeling that he had been tricked.

"The process of parsing materials is at least analysis and observation at the atomic level, which of course cannot be seen by the primitive eyes of your two humanoid beings. Star Core replied confidently.

"No, you have to react a little if you can't see it, you have to at least have a voice. There was no reaction, Wang Fen didn't agree, it would make him look stupid.

"Do you mean that when you make repairs, you will explain them? Although Xing Core didn't understand what dubbing meant, it still knew Wang Fen's intentions from his subconscious.

"Uh-huh. Wang Fen nodded, and continued to pinch the star core for him to hurry up, he didn't want to be outside alone in the middle of the night for too long.

"Raw materials, understood!"

。。。。

"Structure, Explanation!"

"Scheme, screening!"

。。。。

"Choose, done!"

The star core kept saying in Wang Fen's mind cooperatively, and the rearview mirror in Wang Fen's hand still didn't react at all.

"Stop, stop, stop! Your explanation is too simple, right, have you ever seen a betta, at least at the level of a game commentary. Wang Fen stopped kneading, waved his hand and said, he couldn't stand the star core's way of explaining, he didn't have any passion at all, and it was too simple, he didn't know how the star core was operating.

"If you explain it in too much detail, you don't understand it at all, but before it was explained according to your comprehension, and that's all you can understand... Xinghe explained, it's not that it's lazy at all, it's that Wang Fen is too stupid.

Only when Wang Fen uses the function of the star core to map space and greatly improve his thinking ability and information processing ability can he concretely understand the significance of these processes.

"What kind of plan do you say?" Wang Fen secretly wrote down in his heart that Xing Core scolded him for being brain-dead again, and then suddenly remembered that there was a link that Xing Core said before, and he couldn't understand it.

"The connecting material of the rearview mirror you bought is too soft, and there is not even a metal connecting rod in it, so it is more difficult to directly transform it with the original material with your ability and the power you use. A better scenario has been analysed based on the current situation and location. Xinghe said disdainfully, it felt that Wang Fen was too picky, and he was reluctant to buy a genuine rearview mirror, but it turned out to be all plastic.

"I bought it on purpose, if I can change something so soft to be very hard, then it will show your ability, tell me what other plans are there. Wang Fen didn't feel embarrassed at all about the soft connection material that Xinghe said, can you expect how much metal is in the ears of such a cheap knock-off car, it's just shells. And he was still a little happy, but he didn't expect that the star core was becoming more and more active now, and would analyze and choose the best plan.

"There's an easier way to do it for you, and it's a shorter time... Let's take local materials" Xinghe has long been accustomed to Wang Fen's thick skin and slamming the door, so he chose a plan that does not cost money.

"What are the local materials?" Wang Fen didn't understand what materials could be used here to reinforce the rearview mirror.

"Go pick up a piece of wood, it doesn't have to be big, it's a little smaller than this joint. Xing Core didn't explain much, and directly instructed Wang Fen to pick up wood.

"Get a piece of wood to reinforce, you're too bad at the star core, aren't you? When Wang Fen heard this, he vomited blood for a while, what are you doing picking up a piece of wood, is it possible to reinforce the inside or tie it to the outside as a support? No, it's worse than a copycat factory, at least you have to get an iron rod to hold up in it.

Wang Fen felt that it was right to pick the door, but he would not use a piece of wood to tie it to the joint, even if he couldn't afford to lose this face.

"It's really not lofty at all, there is no creativity at all, and you are blind to the technology that you are tens of thousands of years ahead. Although he said he didn't want to, Wang Fen honestly picked up a small branch from the nearby woods that he thought looked the most pleasing to the eye.

"Why do you want this wood, you should make it clear to me, don't fool me with any understanding, I understand!~" Wang Fen broke off the small branch, left a slap on his hand and said, he decided that if the star core said that it was tied outside, he would not agree.

Since Wang Fen had such a strong thirst for knowledge, the star core could only slowly explain to him why he used this piece of wood.

It wasn't intended to be tied to the outside of the ears with wood, but it needed the material contained in the branch.

The ability of the star core to use electrical energy to modify objects can be carried out to the macromolecular level for non-conductors, but it is now too laborious to process at the molecular level, which is why it is too time-consuming to directly modify the plastic of the car ears.

The nanometer level processing accuracy is much easier for the star core.

The cellulose nanofibers in the wood are the raw materials used by the star core for transformation and reinforcement.

Cellulose is the most abundant biopolymer on the planet and is found in large quantities in the cell walls of plant and bacterial cells. Cellulose is a long chain of glucose molecules distributed in a complex network that provides structure and support to plant cells.

Wood is basically a network structure composed of cellulose molecules, and the cellulose molecules in wood are composed of lignin in a matrix. Thousands of years ago, the Chinese invented papermaking, and after all the processes of producing wood pulp, the matrix-like lignin molecular beams were broken and eluted into a suspension that remained in the water. These cellulosic wood fibers are only a few tens of microns wide and about a millimeter long.

Wood pulp cellulose, when dried, is not the strongest type of material known to man. After all, paper is made from cellulose from wood pulp and doesn't show extraordinary strength or stiffness, but paper can be sharp at times, especially when it's very, very thin.

After further processing of the wood pulp, the cellulose fibers are broken down into nanofiber molecules, which are about one thousandth the size of the cellulose molecules. The nanofiber molecule uses long glucose linear chain molecules stacked into a three-dimensional structure by hydrogen bonds. Although the hydrogen bonds between the cellulose molecules are not "true" chemical bonds, the bond between the bonds becomes quite strong when the strength and stiffness of the nanocrystalline cellulose are increased.

A cellulose nanofiber is only 3 to 4 nanometers in diameter, which is about 20,000th the size of a human hair. Although the pulp itself is not hard, in reality, the cellulose nanofibers that make up the pulp have strong roots. These cellulose nanofibers are aggregated together to create a strong material.

Now many countries are already producing this material, compared with steel, the current production of cellulose nanofiber materials, only one-fifth of the weight of steel, but more than five times the strength, of course, the price is more than ten times. To put it simply, the body armor made of this thing is lighter and stronger than any Kevlar body armor.

In addition to being used alone, cellulose nanofibers can also be incorporated into other materials in small amounts to improve strength, and plastic is one of the materials that is very suitable for combining with it.

"Are you saying that what nanofibers are refined from this wood, and then combined with the plastic of this car's ears, it will be very strong?" Wang Fen listened for a long time and roughly understood the reinforcement principle of the star core.

"Yes, the cellulose nanofibers of this branch and the original plastic of the rearview mirror, combined in a special way, can be at least 30 centimeters thick steel plate strength. Although this intensity is not absolutely constant, it is generally impossible to hit a car on the earth. The star core said modestly, now the human process can reach five times the strength of steel, and if the star core is processed and transformed, it will no longer be worthy of its name.

Of course, the rigorous star core will not say that the ears of this car will never be knocked off, after all, in its opinion, this strength is too low, and only a prerequisite can be added.

"Well, it's still not hard enough, but it's barely acceptable. Wang Fen's mouth was reserved, but his heart was happy, thirty centimeters thick steel plate, that is really the thickness of tank armor. Who dares to say that it is a copycat, and who dares to say that this car ear is not good.

"What are you doing in a daze, hurry up and start!" Wang Fen held the star core and the branch tightly, his eyes wide open, trying to understand how the star core extracted cellulose nanofibers from this wood, and also wanted to know what the transformed car ears looked like.
