please make me king

Chapter 844
Another day later, Dudu Zhang finally found a jewelry craftsman with good craftsmanship, and he deliberately brought him to the city of Yanxiang to meet Zhang Shun.

After a few polite words, Zhang Shun let him sit down.

The man was so frightened that he knelt on the ground and begged for mercy: "Grandpa, just let me kneel, it's so practical!"

As a modern person in his previous life, Zhang Shun couldn't stand this.He persuaded him a few more words, but seeing that he was determined to do so, he had no choice but to give up.

Immediately Zhang Shun asked: "I heard that you are good at casting gold and silver jewelry. May I ask what is the difference between you and cast iron cannons?"

"Sand is used to make jewelry, and clay is used to cast ironware. There is a difference between models!" The old craftsman replied honestly without a word of nonsense.

"How about using sand? How about using mud?" Zhang Shun also liked this man's straightforwardness.

"It is difficult to shape with sand, but the casting is fine; using mud with porous honeycombs, you can cast large pieces!" This craftsman is also very knowledgeable.

"Oh? I want to cast a cannon, which weighs ten thousand catties. How about using sand?" Zhang Shun asked directly.

"This..." The old craftsman hesitated for a moment, and then replied, "Your Majesty, forgive me, I am old and dull, and I have never heard of the method of casting steel with sand!"

"Because small pieces of iron can be forged, and large pieces can be made of clay. If the king insists on this, I have a non-solutionary method, and I don't know if it will work or not!"

"Sir, please tell me!" Zhang Shun was a little disappointed when he heard that, but he had some ideas, and he didn't know if they would be successful.

"I think sand and mud can be used together. If only sand is used, the sand mold will be difficult to support; if pure mud is used, the king is not satisfied. Then why not mix some clay in the sand to shape it and then cast it?" The old craftsman quickly suggested .

"It's just that this method is unheard of, it's old man's nonsense, if it doesn't work, please don't blame the king!"

"Don't worry, I won't blame you whether this matter succeeds or not!" Zhang Shun originally wanted to ask the old craftsman's name.

It's just that now seeing him a little scared, in order to avoid misunderstanding, he had no choice but to comfort him: "If this thing is done, this king will reward you!"

The old craftsman saw that Zhang Shun was a kind-hearted person, so he quickly kowtowed and thanked him, but he didn't mention it.

When the old craftsman went down, Zhang Shun turned his head and asked, "What does Mr. Zhang think about this matter?"

"Then... then try?"

"You're right, you should try it first!" Zhang Shun emphasized the last two words, and then continued, "First try the effect of pure sand, mud mold and mud sand mixed in a certain proportion."

"Try a few more ratios of mud and sand. Be sure to use sand as the main part, supplemented by mud. Just make the sand mold suitable for use!"

After hearing the words, Zhang Dudu went and ordered people to choose sand, clay and other models for casting.

This time it wasn't for casting cannons, it was purely to verify the effects of various models, and it didn't take much effort.

In the early morning of the next day, Dudu Zhang knocked on the door, beckoning Zhang Shun to go to the smelting office to check the situation.

Gao Guiying pouted her mouth and wanted to get up very unhappy, Zhang Shun persuaded: "Since you are sleepy, go to sleep a little longer and let Wukong accompany me!"

"Ah~" Gao Guiying opened her mouth and yawned indecently.

As she hurriedly put on her clothes, she replied angrily, "Don't! Daddy got his throat cut by accident last time, maybe your wives are jealous of me. If this time I fall Can you still live the rest of your life if you are a handle?"

"It's not your fault, what are you worried about?" Zhang Shun comforted him while grabbing a fragrant flying fish suit and putting it on.

Taoist gowns, straight gowns, official gowns and other clothes that are popular in this era are very comfortable to wear, but they are not very convenient for movement.

But now that Zhang Shun is a person of status, he can't wear short brown clothes like before, so he has to choose the flying fish suit which is more convenient for walking as his normal clothes.

Needless to say, Zhang Shun is tall, with a broad frame, and looks really majestic in his clothes, with both civil and military skills.

Not long after he was dressed, Gao Guiying picked out a certain black Tang scarf and put it on for him, then Shi Shiran left the room and called Wukong and other guards to go to the smelting place together.

When I arrived at the place, I tried to make iron parts, but the mold has not yet been opened.In front of Zhang Shun, Zhang Dudu ordered the craftsmen to break open one by one, and let Zhang Shun check them one by one.

Needless to say, the iron parts cast with sand molds have a smooth surface, with almost no holes and pits; while the iron parts cast with mud molds are mostly pitted and unsightly.

As for the result of sand-sand mixing model pouring, the law is basically that the more mud there is and the less sand is, the rougher the casting will be.

Since there is no big problem with the appearance, Zhang ordered by the way: "Find someone with a sledgehammer, give me a few hard hits to see, and test the performance of the casting!"

Originally, these objects had to be tested for their tensile strength, just to verify the difference between the clay mold and the sand mold. This time, the castings cast were mainly in large pieces. With the simple tools of this era, it is really impossible to test.

Zhang Shun simply adopted destructive experiments to verify the impact resistance of these iron pieces.

Zhang Dudu hurriedly called two strong men, one of them carried a big hammer, and according to Zhang Shun's request, he smashed it down several times with the hammer.Zhang Shun stretched out his head to look, and saw that some were undamaged, some were damaged at the corners, and one piece was even smashed open.

"Okay!" Zhang Shun inspected for a long time, pointed to two of the molds and said, "These two are good, what is the ratio of mud and sand?"

Dudu Zhang looked at it, and quickly responded: "One catty of mud uses [-] catties of sand, and the other is [-] catty of mud and sand is used for nine catties!"

"Oh, it's five percent and ten percent clay!" Zhang Shun nodded and said, "These two are good."

"Not only is the surface of the cast casting smooth and clean, it will not break when hammered, but the shape of the mold is stable, it will not break when standing, and it is ready for use."

Dudu Zhang is not blind, so he naturally holds the same opinion.

So, he asked for instructions: "Since this is the case, why not take the number, make a sand mold, and then try to cast a cannon?"

"Yes!" Zhang Shun nodded.The effect of the trial casting of the sand mold this time is very good, and many defects of the original clay mold have been solved. It is expected that the casting success rate of the Hongyi cannon will be greatly improved.

Zhang Dudu saw that Zhang Shun agreed, and the grievances of many days were swept away.

He couldn't help arranging manpower to go to the river to collect sand.

Fortunately, Tongguan and Yanxiang are on the south bank of the rolling Yellow River.And this Yellow River is known as "a bowl of water and half a bowl of sand", which is rich in sand.

The [-]-jin Hongyi cannon cast by the rebel army is only one or two feet thick and more than ten feet long. Naturally, the amount of fine sand required is also astonishing.

If you don't prepare as soon as possible, I'm afraid that the day of becoming a cannonball will not be known in which year of the monkey.

Originally, this was the way it was going to happen, but Zhang Shun was so mean-spirited that he asked again: "I don't know what the shape and shape of this [-]-jin Hongyi cannon is?"
