The Rise of Ming Dynasty 1646

Chapter 423
This high-carbon steel is more elastic than the medium-carbon steel used for springs, and the appearance is exactly the same, so it is impossible to find any difference with a simple test, and you may even feel that the quality is better.

However, high-carbon steel is hard and brittle, and the springs made of it are prone to metal fatigue, resulting in cracking or breaking.

Zhu Linmi was also worried that the quality of the products produced by Suji Iron Works was too good, so she ordered to add a small amount of sulfur to them.Sulfur is the main harmful impurity in iron ore, the main hazard is to make steel brittle.

Jianlu bought only the first batch of genuine spring steel, and made more than a thousand flintlocks. After repeated tests, it was found that the effect was really good.

But the subsequent batches were all sulfur-doped high-carbon steel. However, Cai Shiying preconceived that these "playthings" were of the same quality, so it would be no problem to pick out a few occasionally to try.

So Jianlu, who has no steel inspection technology, is doomed to fall into the pit.

Zhu Linmi secretly calculated that as a spring, it can be used repeatedly four to five hundred times, and if it is used on a firecracker spring with a much higher yield strength, it is estimated that it will break after seventy to eighty times.During the production process of these guns, craftsmen have to test them twenty or thirty times, and the lifespan is at most fifty times left.

It's just that there are still three unbroken out of ten. He frowned. It seems that more sulfur can be added, or some phosphorus can be added...

Deng Shan rolled up his sleeves and shouted to the soldiers on the diving board: "Steady your feet, the sea water is bitter and salty, you won't drink less if you fall."

At the side, Sun Qi was instructing people to stack the grain and grass on the cart, then turned his head and teased: "Old Deng, you have a good sense of what you said, when did you fall into the water?"

"Go! I didn't..." Deng Shan glanced at the other side, and couldn't help thinking of the embarrassing incident that he was on the deck of Ruan Jin's boat the other day, but was thrown into the sea by a huge wave, and a salty smell came out of his mouth immediately .

He patted Sun Qi with lingering fear, "Mazi, do we really want to take a boat to the north bank?"

"You're not talking nonsense, Xincheng is on the north side of Qiantang, but how do you attack Jiang?"

"Hey, I heard that that old thief Zheng Zhilong brought more than 600 warships to captives." Deng Shan said in a low voice, "Among them, there were [-] to [-] large warships that were taller than houses.

"Based on the family background of our navy, if, I said, if we don't fight against Jianlu, then we will be trapped on the north bank, and end up in the same situation as Ma Degong a while ago... "

"You know a lot." Sun Qi rolled his eyes at him, "Which time did His Royal Highness say he missed it? Since he said there is no problem, then it should be..." He couldn't help but pause when he said this, "But having said that, in I'm afraid it's wrong to not do any defense on the south bank. In case, I said in case, the northward advance is not smooth, at least we still have room to turn around, right?"

"That's right, especially when the navy can't stand Zheng Zhilong, you say..."

Deng Shan was talking when he heard Sun Qi cough exaggeratedly.He turned his head puzzled and said, "Mazi, what are you... eh, isn't this General Ruan? Hehe, this, just now, you didn't hear what I said about the Navy?"

Since King Lu abdicated and returned to the vassal, the original Zhejiang Navy was formally incorporated into the Daming Navy.Ruan Jin and others were recommended by Zheng Chenggong to join the newly built Qiantang Navy because they were familiar with water warfare.

Ruan Jin himself was personally approved by the assistant king, awarded the rank of guerrilla general, and assisted Luo Ming in commanding the Qiantang Navy.In fact, according to Zhu Linmei's intention, Ruan Jin and other Zhejiang officers and soldiers should first enter the Naval Academy for advanced studies before serving in the military, but the current war is urgent, so we can only make an exception for the time being.

"Of course I heard it." Ruan Jin nodded.

Deng Shan blushed, and quickly explained, "Well, I'm not saying that the navy is not good, I mean that the navy's warships are not good, no, it's not that the warships are bad, it's..."

Ruan Jin raised his hand to interrupt him, and sighed: "General Deng is right, the navy is really not good.

"Not to mention your infantry, even the Navy's own people don't believe they can defeat Zheng Zhilong."

Deng Shan thought that Ruan Jin was talking ironically, and was about to slap himself in a hurry, but he heard that Ruan Jin continued: "Even if the main warships of the navy are now in Qiantang, with the power of the cannons carried by the Shaowu and other ships, they may be able to Some small victories have been achieved. But there are more than [-] enemy ships, of which nearly [-] are more than a thousand ships! Once the battle starts, our navy will be surrounded. If you lose the ability to move at sea, you will be defeated No amount of cannon can escape.

"What's more, the admiral has led more than 30 warships with the most powerful warships away from Qiantang for many days. Right now, there are only about [-] ships here, and there are only five big ships. How can we stop Zheng Zhilong's menacing attack..."

"You said Admiral Zhu left Qiantang with [-] boats?!" Sun Qi was shocked when he heard the words, "His Royal Highness ordered me to board the boat and go to the north bank tomorrow to attack the captives. Why is he at this juncture..."

When he said this, he looked at Deng Shan and said in shock: "Didn't Admiral Zhu run away cowardly?!"

"Stop talking nonsense!" A voice scolded from behind the three of them, "Be careful and I will punish you for disturbing the morale of the army!"

Deng Shan and the others looked back, only to see that Zhenzhen came with several guards, and hurriedly saluted: "I have seen the general."

Sun Qi smiled again and said: "The general is too serious, we just discuss the situation of the battle."

But Deng Shan spoke bluntly, "General, tell me, how can I be so worried about the situation of the Navy..."

Zhen Zhen frowned slightly, and said solemnly: "This time crossing the river to the north, you are not the only one. I will personally lead 3000 troops from the Polu camp to attack Fuyang, and 3000 troops from Yu Shilang's troops will attack Jiaxing. Your Highness will even personally attack Songjiang. government.

"That is to say, the main force of our army will spread out along the Qiantang line to fight decisively with the captives. Your Highness has always been cautious and prudent, and there has never been a mistake. This time, such a large formation has invested tens of thousands of troops. If His Highness is not fully sure It won’t put me in danger.”

Seeing that Deng Shan was still puzzled, she continued: "Let me ask you now, since His Highness raised troops in Fuzhou, has there been a single miscalculation against the enemy?"

"That's not true..." Deng Shan hesitated for a moment, and finally gritted his teeth, "Damn! I'm afraid of a ball! I went to Polu camp to kill Jiannu, so I didn't plan to live! I can kill a few more in Xincheng tomorrow. A Tartar is winning!"

Zhen Zhen patted him with a smile, "This is just like the Brother Deng I know."

Although she was boosting morale everywhere, she was also quite uncertain in her heart, after all, Zheng Zhilong's fleet was too powerful.It is entirely out of her trust in His Royal Highness that she is so resolute.

Speaking of which, Zhu Linmi did have a very safe strategy to ensure that the Qiantang River was controlled by the Ming army, but he could not tell the details to his officers.

He wanted to make them feel at ease, but the matter was of great importance. If someone accidentally leaked the news, Jianlu would take precautions in advance, and the navy would also be in danger.
