The bazaar is booming, because of the hundreds of people joining, the voices of people are gradually noisy, and the atmosphere is slowly lively, just like the big market of an ordinary city.

The Candle Flame Saint Monarch walked to a stall with all kinds of stones with Heavenly Sin, and Xiao Wu Xiaoling hurriedly followed, curious to see what this pair of masters and apprentices were going to do.

Heavenly Sin sighed, and asked the Candle Flame Saint Monarch to buy a good piece of wood from other stalls, and used the method of controlling things, and his fingers just lightly swiped over the wood, and the wood was silently divided into many parts by him as if it had been cut by a sharp blade. Putting those parts together, they form a wheel again.

It's just that this time the Candle Flame Saint Monarch noticed that during the assembly process, all the parts seemed to be 'glued', as if they formed one, obviously without using nails, but the whole became extremely strong, he felt very puzzled, but now was not the time to ask, so he could only write it down silently in his heart.

In fact, this is the unique microscopic control method of heavenly sin, as long as the molecules at the junction of the wood are 'scattered' and 'recombined', they will be perfectly linked into one, naturally, this method is still 'too incredible' for this world.

Then a complete stone is chosen, and the density of it is cut into a ring and placed on the wooden wheel.

While working, Tiansin said to Xiao Wu Xiaoling without looking back: "Two senior sisters, do you know what maturity is? ”

The two girls glanced at each other, and couldn't help but laugh and said, "Oh? I don't know, then please ask the 'little young' junior brother to sue us. ”

"Of course I don't know much about it, but I've heard others say what maturity is, and I feel quite right." ”

Xiao Ling said: "Oh? What is it? ”

"That person once said that there are several manifestations of maturity, but among them, I think the most suitable for the two senior sisters...... That is to say, mature, what is mature? As long as the illusion in your heart that this teacher is the whole world disappears, you will truly mature. ”

Xiao Wu and Xiao Ling were all stunned, and they couldn't realize it for a while, but the Candle Flame Saint Monarch was shocked in his heart. He found that the only sentence of Heavenly Sin actually revealed the biggest drawback among their sects! Disciples often regard the affairs of the sect as the whole of their lives, thinking that this is the whole world, so the moment they walk out of the sect, they will run into walls everywhere and be incompatible with the whole world.

First of all, there is the difference in 'rules', and the laws of the sect and the laws of the world have an essential conflict. The second is interpersonal relationships, even the most down-and-out disciples in the sect will have three or two friends, and at the last time, there is a master behind him to support, and when he goes outside, he is facing the whole world by himself.

After all, Xiao Wu was older, and she was the first to understand, and she also understood how many thought-provoking ingredients there were in this simple sentence, and then she smiled reluctantly and said: "Xiaotian, you said that there are many standards for maturity, so what else is there besides this?" ”

Tiansin smiled and said: "Maturity is not like the kind of ethereal thing that some people say, in the character, dedication, enterprising, or anything that can't be reflected, not to say that there is responsibility or maturity, when a little fart child is in front of a little girl with tears on his face and waving a stick in his hand to drive away the wild dog, he is also a responsible person, but he is not mature, nor does it mean that he knows that he is not a wild dog opponent, he should run away quickly and give up the little girl directly, this is called maturity, Because this matter has nothing to do with maturity at all! Mature, hehe, it's just a toy difference. ”

Xiao Ling disagreed, pouted and said, "Still playing with toys, what is it called maturity?" You little kid is talking nonsense. ”

Heavenly Sin smiled: "Hehe, do you know what the biggest * and enterprising spirit is in the world? It is the impulse of a child when facing a toy, his heart is filled with toys, and he can't tolerate anything else, if an adult can have such determination, I am afraid that there is nothing in the world that he cannot do. And mature, the stone eggs played by children have grown up and become a piece of land at the head of the village, and the puppet dolls they play with have become ...... Woman. ”

Xiao Wu and Xiao Ling made a big red face at the same time, and Xiao Wu said even more hesitantly: "You are changing the law to say that you are a mature little brat, aren't you?!" ”

Heavenly Sin smiled and said, "Of course, so you have to do your duty as a toy, hehehe...... It's like this thing, which is at best a little toy made up by a child, and can be put here and now in a particular task...... Change the world! ”

As he spoke, he suddenly turned the stone-clad wooden wheel that he had just assembled, and it spun perfectly, without a trace of shaking.

"Come, bring me a blade, whatever you want."

Heavenly Sin waved behind him, and the Candle Flame Saint Monarch hurriedly picked up an ordinary long knife from a stall, only threw down a few spirit stones and replaced it, handing it to Heavenly Sin's hand.

"Hehe, this knife is not bad, but the shape is a little worse, what do you want?"

"Whatever, the teacher still hasn't seen what your purpose is in doing this."

Heavenly Sin rolled his eyes and said, "You've done it all this and still haven't seen it?!" Hey......"

Sighing helplessly, he directly put the blade of the long knife on the wheel, only to hear a sound, with a spark splash, the long knife was sharpened and changed shape, and the original good blade turned out to be uneven, looking extremely ugly.

The sound was too loud, and it also attracted some side glances, but everyone knew the Candle Flame Holy Monarch, the sect leader of the Instrument Sect, and they didn't dare to go too far ahead, and looked at it from afar while shopping for things.

Xiao Ling stepped forward in two steps and frowned: "Xiao Tian, you are too wasteful, what a pity that such a knife is broken, this is at least a six-grade blade." ”

Tiansin smiled and said nothing, thought for a while, and suddenly remembered the 'dogleg knife' in his memory, the most suitable knife in the world for chopping. After grinding hard in the middle, the 'waist' of the knife was thinned, and after a few more strokes, a knife in the shape of a 'dog thigh' appeared.

After a few more strokes, a smooth and straight edge appeared, and then he flipped the blade, and after a squeak, both sides of the blade were polished very flat, revealing the snow of the original color of metal.

Stop the wheel, take off the stone ring, put a heavy piece of leather around it, continue to rotate, and polish the blade rapidly, the blade, which was still a little rough, immediately became more flat, and the brightness on it became softer and softer. Heavenly Sin stretched out his hand and took out a small bottle from his bosom, which was black paste and salt, mixed them together and applied them on the skin, and continued to rotate and polish with a little water, the luster on the blade was clearer, and it was already like a mirror that could reflect the surrounding scenery on it.

At this point, under the seemingly simple operation of Heavenly Sin, the original ordinary long knife turned out to be like a precious artifact, at least that kind of mirror surface can only be done by top grinders, and it will take more than a month to achieve.

Heavenly Sin took the knife down, wiped it with a cloth casually, pointed to the mirror on it and said: "The reason why it is done like this is to minimize the unevenness of the metal surface, so as to achieve the function of rust prevention, but it also needs a lot of care on weekdays." ”

The Candle Flame Saint Monarch was stunned, stunned, his head was close and looked closely, and it took a long time before he said in a trembling voice: "This ...... And that's it? And that's the end of grinding? Just such a good kung fu, such a simple process? ”

Heavenly Sin shook his head and said, "Of course it's not over yet, it's not over yet, it's not yet open!" ”

The Candle Flame Saint Monarch was puzzled: "Open the blade? Although this knife is strangely shaped, the edge of the knife is already extremely bright, and it is also very sharp, so why do you still need to open the blade? ”

Heavenly Sin laughed and said, "Sharp? ”

He raised the dog-legged long knife and cut it on a piece of leather casually, and with a bang, he halved a piece of skin, the incision was smooth and the tangent line was straight.

Heavenly Sin sneered: "You call this sharp? ”

That's not sharp enough?!

All who saw it cried out in their hearts.

The Candle Flame Saint Monarch smiled bitterly: "This is definitely very sharp, the average sixth-grade blade does not have such sharpness, it is only possible if it reaches the fourth-grade or above." ”

Heavenly Sin shook his head, raised his head to look left and right, and then pointed to a stall and said, "That stone, buy that stone." ”

The Candle Flame Saint Monarch turned his head and looked at it, his eyes were a little embarrassed, because what Heavenly Sin was pointing at was a huge immortal stone, which was also currency, but it was one level higher than the spar and spirit stone, and the value was much higher. He thought that Heavenly Sin was going to 'get stuck at this point' again to ask him for money, and although he was angry in his heart, he still exchanged the immortal stone and handed it to Heavenly Sin.

Heavenly Sin looked up and down and smiled: "Well, this is good, this is right." Do you know the concept of 'purpose'? ”

The Candle Flame Saint Monarch shook his head and said, "I don't know very well, and I don't like to play chess as a teacher." ”

Tiansin rolled his eyes and said: "It's not that 'eye', you see, in such a small space, there is only this one stone, I will call it 'one eye', like the grinding stone used just now, there are about eight hundred 'small stones' in the same space, I will call it 'eight hundred eyes'." ”

The Candle Flame Saint Monarch suddenly said: "Oh, for the teacher to understand, this purpose indicates the texture of a certain substance. ”

One of them calls himself 'a teacher', but he is doing the things of a student, and the other calls himself 'me', who is obviously an apprentice, but he is doing the things of a master, and outsiders can't help but feel a little funny when they look at it.

Heavenly Sin nodded: "That's right, that's what it means, and now this stone in my hand ...... Hey, hey, there are 100,000 meshes! The edge must be extremely smooth and straight, and only in this way can it cut through other substances, which can be regarded as truly sharp. Soft things can't work, soft things can only grind the edge into an arc no matter how you polish it, although the edge may be very sharp, but the penetration force is not enough, and the feeling in your hand will be much worse. To be straight you have to be something very hard, and this stone is hard enough and fine enough that it can be ...... if it is polished in one direction with great effort."

As he spoke, he picked up the dog-legged long knife and rubbed it back and forth on the immortal stone several times, and then squinted his eyes to look at the condition of the blade, and nodded with satisfaction.

Pick up the leather again, without any strength at all, just put the dog-legged long knife on it, the blade straight at it, and then ...... Let go.

...... An extremely small sound, the knife fell quickly, directly into the stone slab on the ground, standing there, the tail of the knife kept trembling and humming, and the leather ...... It wasn't until the knife hit the ground that it was divided into two halves at a uniform speed from top to bottom, falling on the left and right sides, and the incision was smooth and even had a little shiny.
