...

Ou Chuyang took root in Duan's blacksmith shop and devoted himself to the method of smelting. In the blink of an eye, three months passed by. Ou Chuyang had completely mastered the basic methods of iron and steel making, and became Master Duan's capable assistant.

"Brother Ou, Uncle Duan." Xu Ruonan came in with a big bowl of fragrant broth. "Today, the winter solstice, I stewed a pot of mutton soup at home. Daddy asked me to bring some to you and Master Duan."

"It just happened to be a pot of good wine today." Master Duan said: "Go and invite your father to come and have a festival together."

"Okay!" Xu Ruonan said before going out: "Uncle Duan, you should marry a family. Otherwise, the family will be so deserted during the holidays. Do I want Aunt Zhang to find you?"

Master Duan laughed, "I see, let Aunt Zhang help you become a matchmaker first."

"Uncle Duan!" Xu Ruonan said coquettishly, turned around and ran out.

While eating, Mr. Xu looked at Ou Chuyang and said, "It's winter, why are you still bare-armed? Let Ruonan sew a cotton jacket for you so that he won't freeze your body."

Xu Ruonan's face turned red and she lowered her head and said nothing.

"It's okay, the blacksmith shop is very hot, and it's burning all day long." Ou Chuyang smiled and bent his arms, "Look, my young meat has become a repot."

"Are you just staying in the shop and not going out?" said Master Duan: "If a man's needlework is famous far and wide, that's really great."

"Oh, then I'll trouble Ruonan."

"No trouble..." Xu Ruonan responded softly.

Dad Xu and Master Duan looked at each other and smiled without saying a word.

...

"What a pity..." Master Duan sighed as he stroked the newly made sword: "If this steel is a little purer, this sword can become a treasure."

Ou Chuyang knew that the sword cast by the swordsman is called a craftsman, and the sword cast by the sword caster is one level higher, called a treasure. Each level is divided into three levels according to quality: good quality, treasure, and outstanding quality.

The Mingshuang sword that Mu Wanqing bought that day was a good treasure, worth up to 7,000 yuan. If Master Duan's sword could reach the level of a precious treasure, its value would be several times higher and it would become a real treasure in a sword.

"If we want to improve the purity of steel, should we reduce the proportion of toner?" Ou Chuyang asked tentatively.

"If the toner is reduced, the temperature will decrease. If the combustion is insufficient, there will be more impurities." Master Duan shook his head. "Now this ratio is a universal steelmaking formula in the world. It can be said to have been tempered for a long time and cannot be changed easily. Unless... a high-efficiency and impurity-free combustion aid can be used to replace part of the toner."

"Cylinder...Cylinder..." Ou Chuyang walked aside and began to think.

...

Ten days later, a water truck was set up on the small river behind Duan's blacksmith shop. A long iron pipe stretched out on one side of the water truck and connected it to the furnace. A wooden shed was set up next to the furnace, and two steel pipes stretched out from the wooden shed, one was raised high and the other was inserted into the furnace.

The helpers in the blacksmith shop pointed and were puzzled.

"What's this to tinker with?"

"Who knows? Ou Chuyang said he wanted to test a way to improve the purity of steel."

"Tao! Master Duan has been practicing steel for half his life, but he has never seen any strange things come out. He, Ou Chuyang, has only been an apprentice for three months and thought he was a great person?"

"Who knows, let's just watch the show here to see what trouble he can do."

Ou Chuyang was accepted as his only disciple by Master Duan when he first arrived, which really made many veteran helpers quite dissatisfied.

"Immediately!" Ou Chuyang ordered loudly, deafing the surroundings, and then three helpers on the flushing truck shouted: "Tread hard, hurry up!"

"Boom!" The fire in the furnace became more and more fierce and the temperature was getting higher and higher. The helper in charge of watching the fire in front couldn't help but take two steps back.

"This..." Master Duan was surprised at the raging fire in the furnace.

"This is called - electrolytic water-generating oxygen-enhancing combustion method." Ou Chuyang smiled slightly, and the knowledge learned in class finally came into play.

"..." Master Duan was completely unaware of the so-called, but he was still staring at the furnace with great anticipation.

"It's done?" Master Duan was the first to rush to the furnace entrance, reached out to explore the fire of red steel.

Everyone's eyes were focused on Master Duan's face. Can it really succeed?

After a while, Master Duan took back his sword energy, walked to Ou Chuyang, and patted his shoulder hard, "I'm sure I'm not wrong, you are a genius!"

"Wow!" There was a lot of exclamation around.

Ou Chuyang smiled slightly and said to himself: I am not a genius, I am just standing on the shoulders of the science giant...

"The steelmaking method that has been obtained after thousands of years of hardening and tempering has been so easily changed by Ou Chuyang's smelting apprentice who had only been three months into the entry?"

"He is not a smelting apprentice, he has officially become a smelter."

Becoming a formal smelter means that Ou Chuyang has already started his army. No matter where he goes, he will at least have a safe meal under the swordsman.

"Tiezhu, go and move a few jars of good wine. Ergou, go and cut ten kilograms of beef and ten kilograms of ribs... Forget it, if there is any good dish, just buy it back." Master Duan ordered with great joy, "Today everyone has opened their food and drink, and they will not stop drunk."

...

"Dad Xu, what else do you have to hesitate about? Our Mr. Chen Shihua is the brother-in-law of He Wenyuan, the eldest son of Elder He of Yundu Sword Sect. If you get into this marriage, will you still be worried about being so popular and drinking in your life?" The matchmaker encouraged her to persuade her.

A young man dressed as a rich young man, sitting aside, drinking tea leisurely, with a hint of pride on his face. He must be Chen Shihua and Chen Zili, whom the matchmaker said,

"This..." Mr. Xu said in a dilemma: "Thanks to Mr. Chen respect her little girl, it is a blessing for her. But... it's just a few days ago, the old slave had already agreed to Master Duan to betroth his little girl to his disciple Ou Chuyang. Look at this matter... it's really a coincidence..."

"Is that true?" Chen Shihua reached out and said, "Where is the engagement contract? The letter of appointment! Take it to me for a look!"

"This... although the letter of employment has not been issued yet, this matter has been agreed upon. If you don't believe it, you can ask Master Duan."

"Stop using Master Duan to suppress me. Without a letter of appointment, this marriage will not count. In two days, I will bring a sedan chair to pick up people. If you dare to push and stop me, don't blame me for turning against me. Let's go!"

After leaving the door, Chen Shihua whispered to the left and right: "Look at the boy named Ou."

...

"Chu Yang, this sword has been recast. You can run and send it to the Yundu Sword Sect." Master Duan ordered.

"Recast?" Ouyang asked, "Is it the broken sword repaired?"

"No." Master Ou replied: "After the sword is cast, higher-level materials can be used to improve the quality. However, only the original sword-casting master of this sword can be recasted. Because only the original sword-casting master of this sword is clear about the material characteristics and casting techniques of this sword."

"So it's possible..." Ouyang took the box with his hands and carried it on his back, "Master, I'm going."

Walking to the foot of Yundu Mountain, Ou Chuyang stopped and took a breath, looking at the box containing the sword, and became curious. After coming to this world, he heard too much about the sword, but he had not touched the sword with his own hands. What did it feel like?

Seeing that no one was around, Ou Chuyang took out the sword and held it in his hand.

"It seems that nothing special?" Ou Chuyang held the hilt of the sword in his right hand with his right hand.

Suddenly, a heat circulated above the fingertips of the middle finger.

"It's true that something strange!" Ou Chuyang let go of his right hand and the heat flow disappeared.

Ou Chuyang stared at a dark green gem on the hilt of the sword, stretched out his index finger to tentatively point it, and felt the heat flow coming into his index finger again.

"It's the heat flow generated by this gem." Ou Chuyang tried several other fingers, and it was tried and tested again and again.

This gem is not a sword crystal stone. Is it also contains sword energy? Ou Chuyang changed direction and held the hilt of the sword with his right hand again. This time, the gem was not touched by his fingers. The gem was tightly pressed on the palm of his palm, but there was no heat flow in his palm.

Palm? Sword Gate?

I understand! Ou Chuyang suddenly stood up and his heart suddenly became clear.

If the sword gate is not open, the tendons and veins are blocked, the palm cannot sense the heat flow, and the sword energy cannot be absorbed from the sword crystal stone, so it is impossible to practice sword techniques. This is the secret of the sword gate!

But why can my fingers sense heat flow? Will other people do this? Or is it the only one who is the exception...

Although there is no answer to these questions for the time being, Ou Chuyang still couldn't hide his excitement. With a "clang" sound, he drew his sword in his hand, and the heat flow continued to flow into his fingertips.

Is this the sword of this world? Is this the feeling of a sword coming out of nowhere?

Suddenly, Ou Chuyang's mind lit up, and the golden light was magnificent. It was the golden light shot into his eyebrows in the mysterious hall! Ou Chuyang finally realized that it was the word "sword" in ancient seal script!

A strong feeling in his heart was about to burst out, and Ou Chuyang waved sixteen swords in a row according to this feeling, just like sixteen strokes, writing the word "swish" in the air.

After writing the word "Sword", Ou Chuyang felt the heat flow from his fingertips getting hotter and stronger, and the feeling in his heart became stronger and stronger. He couldn't stop at all, and he stroked and stroked one by one, writing the word "Sword" in the air continuously. He just felt that the more he wrote it, the smoother he wrote, the more comfortable he wrote.

Ou Chuyang was completely immersed in it, as if his pores were relaxing, extremely comfortable. The sword word in his mind became clearer and clearer, as if it emitted a simple and desolate atmosphere, and seemed to convey various profound messages...

I don’t know how long the sword has been dancing, nor how many sword words have been written. When the sun sets, Ou Chuyang stopped, and sweats are completely soaked in his cotton jacket, but he doesn’t feel tired at all, he just feels extremely happy in his heart.

"I can finally practice swordsmanship!" Ou Chuyang whistled to the sky, and he firmly believed that his feelings were absolutely correct!
Chapter completed!
