Dawn of the Empire

Chapter 108 Sighing Your Suave Talent (3)

After sitting down in the restaurant, Chun Yuzhen poured down a large mouthful of strong wine called "Sweat and Blood", and he didn't care if the wine spilled on the skirt of his clothes. He stared at Zhao Xingde with red and swollen eyes and said, "You think I'm really a business?" Did Coupon Piao lose all the family property?"

"Why is that?" Zhao Xingde said indifferently, filling up the wine bowl in front of Chun Yuzhen.A person who begs for death must have something pent up in his chest, and when he is done venting, he may not want to die anymore.Li Ruoxue sat beside him quietly. After she realized that Chun Yuzhen had extremely strong self-esteem, she never looked at him with pity. "Scholars can be killed but not humiliated." Li Ruoxue also felt that he should be persuaded. There are fewer and fewer real "scholars" in this world.

"Have you seen the reward list of the Ordnance Department?" Chunyu Zhen said hoarsely.

"I see." Zhao Xingde nodded, he guessed what was going on, and couldn't help secretly sympathizing with Chun Yuzhen in his heart.

"I found that using a method to cast cannons can greatly reduce the weight of the cannon and increase the chance of successful casting." Chun Yuzhen said slowly, he took a sip of wine, and sighed, "But no matter what, it can't be completely successful. The things that come out either have cracks or holes, and once the gunpowder is used violently, the chamber will explode. They are all defective." He took another sip of wine, which is the habit of blacksmiths in front of the furnace. After drinking, he also likes to spray a sip on the sword being forged, watching the blue flames rise.But Chun Yuzhen despised this kind of boring behavior.

"Then how are you going to cast the cannon?" Zhao Xingde asked slowly, he wanted Chun Yuzhen to talk as much as possible, so as to let out the stagnation in his heart.

Chun Yuzhen was taken aback, every blacksmith has his own secrets, especially the casting technique related to the gold reward, how could Zhao De ask so lightly in the restaurant.He was stunned for a while, then suddenly smiled and said: "I am really in a trance, this cannon has never been able to be cast, and the family property accumulated by the four generations of my Chunyu family has been wiped out. I am still like a treasure for this deadly casting technique Hold back what to do."

He sighed, let go of his defenses, cherished the broom, but said slowly about the cannon-casting technique that has never been successful once: "The clay mold wooden molds are used to cast cannons. After casting the cannons, the molds are broken, so that every time The molds are all redone, and the molds are slightly different each time, so that the copper cannons cast are different each time, and the quality is uneven. I thought that if I switched to iron molds, I could cast more cannons with one mold, and each time The cast cannons are of the same size and style, so they are less likely to fail." At this point, he took a big gulp of wine and coughed several times, and he was quite proud of his idea at the beginning.

Zhao Xingde was slightly taken aback, the cannon-casting technique Chun Yuzhen mentioned brought back some memories that he had kept for a long time.If what he said is true, Chun Yuzhen can be regarded as a pioneer in the art of casting cannons.

After Chunyu Zhen drank the strong wine, his eyes were also a little dazed, and he continued to mutter: "I tried to cast a few bronze cannons. After failing, I smashed the cannons to pieces. I carefully inspected the cracks and pores inside, and found that the reason is not It was successful because the copper water was poured in. The outer part condensed first, fixing the outer circle of the cannon. Pour cold water into the mold of the cannon, let the inner wall of the copper cannon cool first, and then the outer wall, so that the inside is already hard, and the outside has to be squeezed in." He raised his head and grinned at Zhao Xingde, "You don't know, this When the molten iron and copper cool down, squeezing is less likely to cause bad things than pulling, and sometimes it can make things better."

Zhao Xingde also fell into deep thought, his eyes wandered, and he said in a low voice: "I know."

There was a hint of disbelief in Chunyu Zhen's eyes, and then he turned sad, bowed his head and said: "At that time, I had already failed to cast several cannons, and the ancestral blacksmith's shop was already unable to make ends meet. Now that I discovered the secret of successful cannon casting, I naturally refused to give up, so I mortgaged the shop to others, and after raising enough money, I continued to try casting."

"Have you really tried casting?" A trace of excitement flashed in Zhao Xingde's eyes. Chunyuzhen's secret brought back memories that he thought he would never touch again. The seemingly ordinary person in front of him was actually a real genius. He brought an extremely advanced casting technique to the world more than 800 years in advance, but he himself was so depressed that he wanted to commit suicide because of this suave talent.

"I've tried it." Chunyu sighed in shock, and said with desolation all over his body: "It still all failed. After today, my ancestral blacksmith shop will also be given up to others. Tomorrow I will have no face to see my ancestors underground. , It’s better to end it today.”

"No way?" Zhao Xingde didn't seem to have heard Chun Yuzhen's words about committing suicide. He frowned and murmured, "You used copper water, which is better than cast iron. Could it be copper?" Is there a problem with the water formula?" He put his right hand on the table, subconsciously drew a finger on the table, and subconsciously took it up with his left hand, as if he was pressing something.

Although Chun Yuzhen wanted to commit suicide, he did not allow others to slander his skills at will, and said with a red neck: "There will never be a problem with copper water. My father came from the Ordnance Department. Although he can't say that he has mastered all skills, he is in charge It’s the section where the copper and water ingredients are used.” In order to keep it secret, the Ordnance Department did not allow a single craftsman to be responsible for the entire casting process.Chunyu Zhen felt slightly regretful, it was precisely because he didn't know the other casting processes of the Ordnance Department that he simply found another way, taking the lead in using iron mold casting and central water injection and condensation.

"If there is no problem with the formula of copper water, then the problem may still lie in the cooling temperature." Zhao Xingde paused, and then said, "Or, there is something wrong with the combination of temperature and formula." He still felt that it was not clear enough, He continued, "I mean, the control of the cooling temperature of the inner and outer walls of the casting mold is not accurate enough." As he spoke, he stretched out his hand to dip a drop of wine, his wrist froze, his elbow pulled slightly, and a straight horizontal line was drawn. After he came out, he dipped in the wine and drew a few strokes up and down, and drew the mold, gun body, and water injection device that Chun Yuzhen had mentioned according to his guess.

Chunyuzhen's eyes were wide open, one was that Zhao Xingde's skillful drawing surprised him, and the other was that he only sketched a rough idea, but Zhao Xingde dissected the structure on the spot, which was similar to what he actually made, even the structure More concise and clear.Li Ruoxue also looked at Zhao Xingde in surprise, she never knew that Yuan Zhi was good at painting, but he created a French style of Shengmo style.

"Ordnance Department's original formula of copper water material must be cooled with wooden molds and clay molds, the formula with the highest probability of casting success. If you don't use cold water and iron molds for cooling, maybe you can also cast successfully." Zhao Xingde suddenly remembered something , paused, and said in a deep voice.

After hearing this, Chunyu Zhen was stunned, as if his mind had been taken away. After a long time, he took another shot of the wine table and sighed: "Why didn't I think of this?" He was silent for a while, only feeling Empty, what he did with all his wealth was nothing but a joke.He concentrated his attention, but his face was a little sad, "But if you use clay molds and wooden molds, it is absolutely impossible to beat the Ordnance Division." After a pause, he bowed his hands respectfully to Zhao Xingde and said: "Mr. It turns out that I am an expert, although I have ruined my family and property, I have also been taught and I am very grateful." After speaking, he wanted to get up and leave.Although he has lost his family property, he still has a lot of craftsmanship. It is not a problem to find a blacksmith shop to be a craftsman, and it is not a problem to support his family. Isn't that how his ancestors saved their family property back then?Thinking of this, Chun Yuzhen secretly scolded himself for being confused for a while, and was even more grateful to Zhao Xingde for saving his life.

"Wait a minute, Mr. Chunyu," Zhao Xingde said slowly while meditating, "I have one more thing to ask."

Chun Yuzhen got his advice just now, so naturally he couldn't refuse at this time, sat down, cupped his hands and said: "Sir, please tell me, I know everything." At this moment, even if Zhao Xingde asked him about the trick passed down from his ancestors, he would not hide it.

Zhao Xingde thought for a moment, put his hands on the table, leaned forward, approached Chun Yuzhen, and said in a low voice: "The art of casting artillery is a major military matter, isn't Mr. Chunyu afraid of the innocence of everyone, and the crime of conceiving a jade?"
