Yang Jibin saw that the furnishings here were similar to those he usually practiced in the refining workshop: a piece of iron billet, a large iron hammer, a small iron hammer, an anvil, a bellows, iron tongs, a burning stove, and a jar of water.

"When the time comes, the trial has officially begun!"

As soon as the words fell, Yang Jibin grabbed the iron billet and threw it into the furnace, and then pulled up the bellows vigorously, the wind entered the furnace, and the flames in the furnace jumped straight up, and the fire instantly became extremely vigorous, and the whole body of the iron billet turned red after a while.

After watching the iron burn red and bright, Yang Jibin picked up the iron tongs and neatly clamped the iron billet and put it on the anvil, and then quickly raised the sledgehammer with both hands and began to clank and beat hard, and sparks splashed for a while.

Under normal circumstances, it takes two people to work together to make iron, with the upper hand holding the main hammer and the lower hand holding the sledgehammer for forging. Experienced in getting started, holding a small hammer in the right hand and iron tongs in the left hand, in the process of forging, the upper hand should constantly turn the iron material by visual inspection, so that it can turn the hard square iron into a square, round, long, flat, pointed and other shapes.

It's just that Yang Jibin can only do it alone, so his strength must be mastered quite skillfully, otherwise there is no iron billet fixed with iron tongs, and a sledgehammer will have to fly out of the anvil.

Ironwork is a very ancient craft, but also a very hard industry, dirty and tired, as the saying goes, "there are three hardships in the world, support the boat, iron, grinding tofu".

Iron striking also needs its own hardness, which is not only a rather physically demanding job, but also the skill of striking iron is also quite important. Anyone who has ever struck iron knows that in addition to strength and angle, skill is equally important.

When Yang Jibin first learned to strike iron, he would only hold the hammer handle with both hands. Fighting hard, not only tired, but also unable to hit a few times, both hands were numb and cracked.

When he first started practicing, Yang Jibin did not master his skills well. The hands are often smashed with skin. Later, after Xiaozi's many metamorphoses, Yang Jibin finally mastered the trick, striking iron has tension and elasticity, a hammer down, to let the sledgehammer rebound naturally, the strength of the hammer is saved a lot, and it will not shake the hand, the effect of hitting is good, clanging. Very rhythmic.

I have to say that striking iron is indeed a man's career. This is because you can't strike iron without strength, you don't dare to strike iron without courage, and you don't want to strike iron without the spirit of hardship. Every time the red furnace is lit up, the temperature is high, and the bellows are pulled, and the sweat is full. Pick up the hammer and you'll sweat. The dozens of pounds of sledgehammers rose and fell. How much strength and bearing is needed.

After Yang Jibin's rain-like beating, the iron billet began to take shape. Yang Jibin picked up the iron tongs and put the iron that was no longer hot into the furnace and baked it. Then quickly pull the bellows, and the flames in the stove jump with the beat of the bellows. Rising in the wind.

When the iron becomes red and bright again, take it out again, continue to beat it with a sledgehammer, and then return to the oven to bake. After the iron sheet becomes red and shiny, take it out and fold it in half, and continue to beat it...... It's just folded and forged over and over again.

The more times the steel is folded and forged, the more uniform the structure of the sword will be, and the higher the quality. At that time, the number of folds and forging was referred to as "refining". The unearthed steel sword of the Eastern Han Dynasty has the inscription of "fifty (refining)" and "thirty [refining]", and the scientific test is the number of folded forging. Today's so-called "100 steel" means that the steel is folded and forged a lot.

The system requires a mortal-level sword, this mortal-level sword, here is not an ordinary meaning, the so-called mortal-level sword, which is equivalent to what people often say, "blowing can break hair", "sharpening iron like clay" type of magic weapon. In this way, Yang Jibin needs to constantly fold and forge this piece of iron billet to meet the requirements.

For such inhuman torture, Yang Jibin has become accustomed to it, this will completely forget everything around him, only the hammer and sword blank are left in his eyes, and at this moment his perverted physical strength and strong perception play a huge role.

He continued to fold and forge 100 times without stopping for a moment, during which Yang Jibin also used iron tongs to clamp the long sword, and switched to a small hammer for precise beating, carefully forging the details. The weight and strength of the hammer used to hit different shapes of iron are different, and the strength and angle of the hammer are all exquisite.

Yang Jibin finally perfectly turned the iron billet into a sword billet of "100 steel", and the next process was quenching. The key to whether the weapon can be hard but not brittle, sharp enough and tough enough, lies in the process of quenching, which determines the quality of the forger's craftsmanship.

Quenching is one of the metal heat treatment processes. The so-called metal heat treatment is to heat the metal workpiece in a certain medium to a suitable temperature and hold it for a certain time, and then cool it at different speeds. Different heat treatment processes are used for the same metal, which can obtain different performance properties.

The main function of quenching is to improve the hardness and wear resistance of metal workpieces. After quenching, the steel becomes hard, but at the same time brittle. In order to reduce the brittleness of the steel, the quenched steel can be kept warm for a long time at an appropriate temperature, and then cooled, this process is called tempering. Tempering and quenching are often used in conjunction to complement each other.

Yang Jibin uses a local quenching process, and only the blade is quenched. Because the cutting edge is quenched, it has a high hardness and is extremely sharp. The spine of the sword, because it is not quenched, has a low hardness, maintains good toughness, and is not easy to break.

With the sound of "squeak", bursts of white smoke suddenly floated up, the quenching was completed, the hundred refining sword was formed, and then the tempering was refired......

"It's done!" Rao is Yang Jibin has been trained by inhuman beings for a long time, and he will feel extremely sore as soon as he stops, and he is really a little unbearable.

"Little pot friend, you have done a good job, you are getting more and more promising. Tsk, this little body is getting more and more stylish, and the muscles all over the body are falling into pieces, it seems that my credit is not small! Xiao Zi playfully looked at Yang Jibin, who had just come out of the trial cave at the moment, and was shirtless, as if admiring a work.

"What do you want to do? Don't mess around, I'm still young, don't scare the baby! Yang Jibin was originally sweating profusely, but at this moment, he suddenly felt a chill on his face, holding his hands on his chest, looking afraid.

"Cut, look at your virtue, and you're pretending to be with the old lady. Do you want a reward? Xiao Zi gave Yang Jibin a fierce look, and stretched out a small fist to gesture at him.

"Yes, why not, you can only try once a month. This time I must give a key, and I was cheated by you again last time, so I got a four-star. Yang Jibin hurriedly put on his shirt and ran to the front of the inquiry machine.

"Fertile Ye, it's really a five-star perfect pass, hehe, brother is getting more and more powerful. Hurry up and open it! After a long period of hard work, Yang Jibin got a bronze key and danced happily.

The Russian Wheel of Fortune began to spin rapidly, and finally froze on a carving knife.

"How is this doing, bullying people, don't give those Zhuge crossbows, Longquan swords, and Shouyuan Dan's good things, give me a small fruit knife." Yang Jibin held the knife, the thickness of his fingers, and protested very dissatisfied.

"It's terrible to have no culture, this is the top-level magic weapon Fengming Carving Knife. It is made of phoenix blood iron, although it is small, but it is concentrated as the essence, the fire attribute magic weapon, indestructible, the carving tool and formation, with an increased chance of success and a chance to attach the fire attribute. Xiao Zi saw Yang Jibin, who had eyes and didn't know gold and jade, and couldn't wait to make a move to him. (To be continued.) )
