defend the truth

The trunk of this ancient ginkgo tree is quite thick, and it takes seven or eight people to try their best to open their arms, and their fingertips touch their fingertips to barely hug each other.The standing height is more than ten feet high, just like a tower!

However, with such a tall and strong wood, what Li Wei really needs to use is only the core of the tree.It is cylindrical, about one foot long, and only one foot and two inches in diameter.The tree core that can eventually be used to make prosthetics accounts for only two to three percent of the raw materials, which is quite a waste of money.

But Li Weizhen felt that since it was a gift for his brother, the best and most superior materials should be used.As long as it is what he owns, there is no need to feel distressed.If this prosthesis can really help the freckled boy to be reborn from the ashes and "stand" up again.Then its value will far exceed ten ancient ginkgo trees.

Beside the furnace, Li Wei was really busy remelting several refined iron ingots into molten iron, and pouring them into the molds he had previously forged and milled.The main body of the prosthesis still has to use metal as the main material, because the plasticity of metal is not comparable to that of wood, and its durability and toughness are far beyond.

The structure of this prosthesis is quite complicated, consisting of many precise parts, so the materials used must be quite strict.After its finished product comes out, it not only has many movable joints, but also cushions, exerts force, bounces... etc. It should be able to do things that normal limbs can do.Its function is definitely not a crutch attached to the body, it is a leg.

Otherwise, Li Weizhen didn't need to sit in the study under the curtain of more than a dozen late nights until dawn, scrapping hundreds of blueprints before he was sure of making it.

There are as many as ten molds of all kinds, large and small, protruding or concave.After the accessories are shaped by the mold, they have to be cut, punched, grooved, cut out gears, spirals, etc. on the forging table with hair-thin wind lines... and more than a dozen processes.

These skills, of course, were all learned in the Taiyi Qilu.Today's manufacturing techniques in the secular world are far from being able to do this.In the past, Li Weizhen also saw molds in other blacksmith shops. When casting a sword, he poured molten iron into it, and the prototype of the sword came out.But his family's blacksmith shop was not used, and his father scoffed at these shortcuts.

Of course, the quality of a completely hand-forged sword is definitely much better, but it is far behind the manufacturing speed.Which one is better and which one is worse, really can't be generalized.

Now, Li Wei really has to use the mold.Because, he is already prepared for not being able to succeed at the first time, he needs to practice his hands first.With the mold, he can mass-produce accessories, which will save a lot of time overall.

And those molds are all new models designed by him.After all, I have only heard of sword models or bow tire models before.Leg models are probably unprecedented.

The finished prosthesis, in short, is a metal cast skeletal body assembled with a wooden shell.

But there are also important parts that are mainly made of wood, and that is the foot joint.Including the soles of the feet and the heels are made of wood, the toes are redundant, so there will not be any.

It is not simply a prosthetic foot, but a combination of three specially made wooden boards.

First take a piece of emerald green tree core with rich aura, pound it into wood pulp and put it in the treasure refining platform.Then continue to decompose the wood pulp until it is refined into strands of thin threads.The thinness of those thin threads is only [-]/[-]th of the thickness of hair.In the end, these thin threads are re-woven together to form a board.

Although this board was born out of wood, its strength is far superior to that of steel, it is quite light in weight, and it has good bendability.

To complete this process, it can no longer be described simply by the four words "concentrate with heart".In the process, spiritual power is extremely consumed, and the requirements for spiritual consciousness are even higher.The failure of refining is small. During the process, if you are not careful, you may go crazy, and that is not worth the loss.

If Jin Cheng was still there, he would never let Li Weizhen take this risk.Because even a master craftsman like him would not be more than [-]% sure.

But today's Li Weizhen can only be regarded as a senior craftsman at best.There should be no high-level craftsmen who are less than the age of the weak crown, and there should be no one in the entire Tiannan Realm.It seems to be enough to be proud, but now it seems that it is not enough.

This skill originated from the handwriting of the ancestor Yun Zhu.Jin Cheng's master passed away early, so he didn't fully master this skill, and he was once quite worried if he couldn't become a master of crafting in his lifetime.Will this inheritance be lost?

Li Weizhen had seen Jin Cheng perform this art of refining, but the other party did not teach him.If he hadn't found the patriarch's handbook from the secret room of the Sutra Pavilion more than 20 days ago, he would not be able to perform this skill on the treasure refining platform now.

Relying on the surging spiritual power far exceeding the average level of monks of the same rank, Li Wei really completed the step of extracting filaments from the wood pulp very well.But to reunite those tens of thousands of thin threads really made his head tingle violently.This is because his divine consciousness has been under too much pressure, and the dominant divine soul is issuing a self-protection warning, hoping to end all of this.

Li Weizhen still tried his best to keep his mind focused, but the painful feeling was so real that he could even feel the liquid flowing out of his nostrils.No smell of blood, not blood, and certainly not snot.He probably already guessed that it was cerebrospinal fluid, and the situation is not good!

"When the manpower is exhausted!" Gradually, Li Weizhen couldn't help but start to doubt himself, whether he was too persistent and pursued perfection too much.Once upon a time, he also joked that Luo Yicheng pursued too much perfection on the architectural level.This time, it was his turn, which was actually a virtue.They are all craftsmen, how can there be no ingenuity of rigorous pursuit?

"Yes, it's ingenuity! I'm not pursuing the perfection of one or two utensils, but the flawless ingenuity in treating the refining utensils, always doing my best, and constantly breaking through the limit!"

Suddenly, Li Weizhen seemed to have a flash of light in his mind, and he seemed to have seen something vaguely.The vague figure of a strange man?

Soon, what attracted Li Weizhen was no longer the blurred face that could never see his facial features clearly.It is a man's incomparably mysterious technique. There are countless thin needles transformed by spiritual power arranged in order, pulling the extremely thin threads to weave neatly and orderly.

In the eastern sky at dawn, the crow blue gradually recedes, slowly revealing rows of clouds like silver scales, and all the clouds are slowly floating in one direction without converging with each other.That strange scene is like a huge silver dragon crossing the sky, wandering here and looking at the sky.

In the end, when the sun is about to rise in the East China Sea, the red clouds are extremely magnificent, but they no longer have the shape of a dragon, and the clouds gather and disperse, just like in the past.

Until the world is clear and the sun hangs behind the branches.Li Weizhen also came down from the treasure refining platform, holding three palm-sized green boards that were as long as his forearm in his hands, rubbed his fingers against his nose, and then smiled lightly.

When Li Weizhen walked back to the forging table, he wanted to put the three boards aside for later use.Suddenly feeling something in his heart, he lifted the board and raised his hand to the sky, raised his head and said, "Thank you!"

This move is inexplicable.If others look at it, they must be puzzled, wondering whether this person's brain is broken due to refining, or even insane?

However, for the patriarch to enjoy the meal, it is really not just a simple thank you, it has to be courteous!

Li Weizhen has already said that he wants to concentrate on refining weapons.Therefore, no matter sooner or later, no one will approach the forging table, so as not to cause unnecessary nuisance to him.

And Li Weizhen didn't let his three apprentices watch and learn from the sidelines, because what he was going to do now was too profound and too out of the basics.The more it is recorded in the mind, the more unfavorable it is for the initial training of refining weapons.That's why, at the beginning, Jin Cheng obviously favored his talent for crafting, but he didn't want to teach him many skills like that.

It's not that fear taught the disciples and starved the master to death.Regarding the matter of teaching art, with Jin Cheng's temper, he might be even more anxious than Li Weizhen.Especially after this guy entered the Imperial War Hall and his days in Qilu were numbered, he was even more anxious, for fear that his mantle would be lost.

But the practice of Taoism is inseparable from the four words "step by step".Even if it is a genius, if it is too overpowering, maybe in the end, it will be lost to everyone, and it is even worse than those disciples with solid basic skills.There have been countless examples of this throughout the ages!

It took two days, after creating five unsatisfactory prosthetics.Li Weizhen squeezed the remaining time, and finally decided to officially start.He also no longer smelted molten iron, but changed a material, and replaced it with fire copper ingots!

When I drilled the hole that day, I still brought out a lot of dark red or orange ore particles in the soil. Those are fire copper ore, most of which are the size of a baby's fist.The quality is quite good. From one catty of fire copper ore, nearly two taels of pure fire copper can be extracted.However, the quality of the so-called high-grade fire copper ore sold on the market can only reach [-]% of that here.

After those fiery copper ores were collected and forged into fiery copper ingots, it should be enough for Li Weizhen to refine one prosthesis, but not two.Therefore, he needed to use refined iron ingots to practice his hands before. There was only one chance, and he was also afraid of failure.

Fortunately, each of the previous five refinements made progress, which gave Li Weizhen [-]% confidence in achieving his goal.Even if it is because the material of fire copper is obviously different from refined iron, and then adjustments have to be made in every process, he still has more than [-]% confidence.

The reason for choosing fire copper as the main material is mainly because the user of the prosthesis is a fire monk.This prosthesis will be a magic weapon, and it must have a longer-term meaning.

And the three boards made from the decomposition and refinement of the tree core, after being precisely cut, polished, and combined into prosthetic feet, not only have excellent shock absorption effects, but also can store power and release explosive power.With a kick, you can even jump higher and run farther than real legs.

Furthermore, although the foot joints are made of wood, because they have been refined by secret techniques, even the pure green furnace fire cannot contaminate them in the slightest.But the strong wood spirit energy can well feed back to the master who is a fire monk.

In Li Weizhen's expectation, this prosthetic limb made of ancient ginkgo tree core and fire copper should not only allow the freckled boy to walk like flying again, but also increase his fighting power!

I'm afraid that in the future, when the young man confronts the enemy, if someone gets close to him and is kicked by him, he will really not even know how to die!

It was another day of rosy clouds, and Li Weizhen, holding the brainchild that he had just forged all night, slowly walked down the treasure refining platform. After a knowing smile, the tiredness on his face could not help but be swept away a bit.He hurried to the bamboo building, because he knew that he no longer had the strength to fly against the wind, but he still hoped to be able to share this joy as soon as possible.
