Chapter 519

As for the special circumstances, it is necessary to poke the knife in. That is, the tip of the knife is responsible for breaking armour and opening the way, and the back blade is responsible for expanding the wound. They perform their respective duties. " The old man said to Tianxing.

In fact, the design of many cutting tools is that even if the tip is broken or worn, other parts can also make enough sections to attack.

From a purely technical point of view, it is to control the angle of attack, control the strength of contact, and make good use of the blade and blade back for defense.

Fang Tianxing handed his long sky healthy qi sword to the old man and said respectfully: "teacher Fu, can you help me see if there is any way to make the sword sharper? I have a strong enemy who practices some kind of method that is not bad. My sword can't stab him, please."

The old man took the Changkong Zhengqi sword from Fang Tianxing, observed it carefully, tried to knock it, and listened to his voice.

The old man exclaimed: "the material of this sword is the only one I've ever seen in my life. It's just that the sharpened blade is rough and crude. It's just that I've made a lot of money. The sharpness of this sword can only be achieved by regrinding it. It only needs a good grindstone to grind this kind of material, otherwise it will be very difficult to sharpen it. "

"My friend has a piece of Jiulong stone, which should be the top grade of grinding sword." Fang Tianxing said to the old man.

The old man said with admiration: "that Jiulong stone and this sword are both supreme gods. They are only seen in my life. I have to see them in order to live a good life."

Fang Tianxing immediately wrote a letter to Cui Chengjian and borrowed Jiulong stone from him.

Three days later, Fang Tianxing received the Jiulong stone from Cui Chengjian. He found the old man and saw the legendary Jiulong stone. The old man's calm face was moved.

Caressing Jiulong stone carefully, the excitement in his heart is beyond words. Through the momentum of his body, Fang Tianxing felt that he was an academician reader.

This kind of reader can be met or not. When he was young, he must have a very rich life and vast knowledge. Fang Tianxing, a famous figure in human society, was very interested.

As for making him a loyal reader, Fang Tianxing dare not even think about it. What he has done is not good enough, so he may not have such qualifications.

"When shall we begin to grind the blade, old man?" Fang Tianxing asked the old man.

"Don't worry. You'll learn the basic knowledge of sharpening swords these days, and then start sharpening in three days." The old man said to Tianxing.

With more understanding of this knowledge, Fang Tianxing just thinks that it is a very troublesome thing. A good knife needs more maintenance. Only good maintenance can keep it sharp.

When it's used to cut. When the direction of the cutting edge is the same as that of the cutting edge, it is easier to cut and sharper. The micro serration of the edge of the blade is also helpful to improve the sharpness.

Burr will greatly increase the cutting resistance of the blade, which is an adverse factor affecting sharpness. A sharp blade should have no burr.

When sharpening, keep a constant angle, although it's not easy. Of course, practice makes perfect, so don't expect to do it well from the beginning.

Three days later, everything is ready. The old man lights incense on one side, which makes people feel calm“ You've learned a lot these days. You have to do it yourself. Only in this way can you be more familiar with the characteristics of the sword and it will be helpful to your swordsmanship. " The old man said to Tianxing.

Fang Tianxing calms his mind, calms his mood and enters the best state. He took the long sky Zhengqi sword and slowly pasted it on the Jiulong stone. He slowly pushed it, gently pulled and slowly pushed it with even force, and ground it a little bit. The old man on one side slowly poured his special abrasive on the grinding edge.

Fang Tianxing didn't hesitate. He grinds slowly along a specific angle. His power is well controlled. Every time he grinds, he grinds the other side evenly, so that the whole sword body can bear the force evenly. He can have a better smooth surface and sharp blade angle.

It's just that slow movement, it needs a lot of patience and perseverance. It's not enough for Fang Tianxing to keep grinding to make the blade sharper.

Some passers-by saw Fang Tianxing grinding the blade. The golden light from Jiulong stone came into it every time he grinded, which enhanced his strength and made the blade more powerful.

It's just that Fang Tianxing is so focused. Passers-by just feel that he is doing a very sacred thing. He just sat here for seven days and seven nights.

Fang Tianxing also felt that he was wasting a lot of effort. In the evening of the seventh day, he finally reached a sufficient level.

Put down your hand and raise the sword. The sword reflects the moonlight in the sky. The light of the sword is soft and chilly. The stars in the sky are attracted by this force, and then the endless stars cover the sword.

Such a strange appearance was soon seen by the farmers nearby. Suddenly, the sky came down. It was impossible to see such a light on weekdays, but for them, it was a miracle.

Fang Tianxing's sword is bathed in the light of stars. On one side, it is engraved with mountains and rivers, and on the other side, it is the stars of the universe. Such forces are extremely powerful, with some mysterious power.

The body of the sword is flowing with a strange brilliance, which makes people unable to open their eyes. The old man on one side caresses his hands and laughs and says: "yes, yes, it causes the vision of heaven and earth. There are infinite blessings in the dark."

Fang Tianxing handed the sword to the old man and said gratefully, "it's not without your help."

"Well, with this sword, general Fang can break the enemy and protect the city for the people, and the people of the whole city can have no worries." The old man said to Tianxing.

"It turns out that you have seen my identity for a long time. You haven't pointed it out." Fang Tianxing said with emotion.

"At first I was just guessing, but now I really understand." The old man said with a smile.

He used to be a senior official in the Federation, and his family was in the central area. Because he didn't like the atmosphere of those powerful people, he came here to live in seclusion.

Such an old man is a real recluse, not envious of fame and wealth, carefree. Those who cry out to live in seclusion, but can not put down fame and wealth, are those who fish for fame and reputation.

The old man didn't bring much money and had no means to support himself. Because he loved knives, he set up a stall to grind scissors and kitchen knives for the nearby residents.

In fact, it's a very ordinary job. Because of the good grinding, the people around him are quite famous, but no one knows that he used to be a senior official of the Federation.

If the masses knew that this man was not amazing, he could only sharpen his scissors and kitchen knives. He was once a senior official of the federal government, they would be scared.

Fang Tianxing did not intend to publicize anything, but those people are ordinary people, do not have to disturb their lives, to protect their lives in peace and happiness, is the responsibility of the soldiers.
