Ou Xuzi asked, "Master, what about you, come with us." ”

The old man shook his head and replied, "I have other things to do, I can't go with you, Xuzi, I have already taught you all my skills, and I have been thinking about myself for many years." Xuzi, your future future will be very difficult, remember the words of the teacher, do not be reckless in everything, and think with your heart. The Zhan Lu Dao is the patron saint of you and Xuan Han, but it is not omnipotent. You are a man, and it is your responsibility to protect your family. We say goodbye. ”

Ou Xuan was a little confused, and it took a long time to say: "No, no, I will be a teacher for a lifetime, and I will not be a father for a lifetime, master, let me provide for your old man." ”

The old man laughed: "What do you say, Xuzi, I am a loose person, traveling all over the world, and the four seas are my home, rest assured, the master will live very well, I am leaving." ”

Ou Xuzi wanted to stop it, but was stopped by Xiao Xuanhan.

"Only the craftsmen heat and forge the fine iron and forge it repeatedly, beating it more than a hundred times, remember, one forging and one weighing and one light, until the catties of the refined iron are no longer reduced, that is, hundreds of steel, used to make swords can be sharpened like clay. These are the words that the master has repeatedly explained.

The master also said: "Many swords and swords in ancient times were made by this method, during the Three Kingdoms period, Cao Cao had five 'hundred refining weapons', and Sun Quan had three treasure knives, one of which was named 'Hundred Refinement'."

However, Ou Xuzi checked the so-called "iron" that Bala Toast bought from the Iron Bureau, only to find that 60% of it was ordinary iron, which could not be used to build weapons at all, Bala Toast knew that the face of the anger was black, but he was helpless, and he was looking for someone from the Iron Bureau to reason, unless your head was in the water, it is illegal to build weapons privately, it would be good for people to turn a blind eye, and the remaining less than 2,000 catties of iron, Bala Toast asked Ou Xuzi how many treasure knives he could build, and Ou Xuzi replied: "Six or seven." ”

Bala Toast's face turned white again, he spent a lot of money on this batch of iron, and in the end he could only build six or seven treasure knives, and he was heartbroken when he calculated it, and each treasure knife was sky-high after folding.

The butler said flatteringly: "Lord Toast, if the blade we have built is really stronger than the Damascus scimitar, and the emperor is happy, that loss is nothing." ”

Bala Toast thought about it for a while and nodded and said to Ou Xuzi: "Master Ou, then please, don't let me throw the silver in the water in vain." ”

Ou Xuzi agreed, he was confident, although there was only less than 2,000 catties of iron left, and the good quality iron was beaten into good steel. That is to say, five catties of iron can be forged into a pound of good steel after repeated tempering, and this pound of good steel is the so-called "hundred steel", because it has more carbon in it, the structure is more fine, the composition is more uniform, and it is the best material for casting treasure knives.

Several furnaces of iron smelted in a row to get more than 1,000 catties of the best quality iron, melt it all in the crucible, make it into a steel plate, Ou Xuzi used the folding method to hammer repeatedly, a steel plate to repeatedly burn and beat hundreds of times, it is really a forging and a light, until the catties of fine iron are no longer reduced, a weighing of the remaining steel has more than 100 catties, put it on the ground and shiny, and it is thick and heavy in the hand, Bala Toast said to himself: "Is this the steel for casting the treasure knife, I heard that the hundred steels that circulated during the Tang Dynasty are just like that." ”

Ou Xuzi was taken aback, and hurriedly replied: "The technology of 100 steelmaking has been lost, and it is not surprising that any high-quality steel will become what it is now after being tempered for thousands of years." ”

Bara Toast believed.

Next is the crucial part, sword casting. Ou Xuzi divided the cooked steel into six parts, took one and put it in the crucible to heat it to melt, Renji took the mountain spring water from the cellar, the water was cold and cold, poured into the vat and was clear and transparent, the Bala Toast Box China Butler and the centurion Rigude were present, standing by the iron stove, the heat wave was pressing, and I couldn't stand it for a while, the China housekeeper ordered someone to bring a chair for Bala Toast to sit on the side and watch, and he walked slowly and said to Ou Xuzi: " Mr. Ou, I brought the best Damascus scimitar, I want to compete with the treasure knife you forged, if this time I can make the Damascus scimitar sink into the sand, I really have Mr. Ou's admiration for the five bodies. ”

Ou Xuzi replied without raising his head: "It's man-made, I have absolute confidence in my own skills, as long as the butler of Chi Na takes care of your own affairs, the treasure knife is out, can't you also get benefits." ”

The housekeeper was stunned for a moment, then nodded and said, "Mr. Ou's words are true, the so-called one person attains the Tao, and the chicken and dog ascend to heaven, please, please." ”

Ou Xuzi looked at him and said: "Then please ask the housekeeper to go farther, it is very hot and dangerous here, in case the molten iron splashes it is not fun, it is a hole in the body, and there is no cure." ”

The butler was startled and hurriedly walked out of the house.
