My Pen Pal Zhu Yuanzhang

Chapter 257: Old Xu Can't Resist Temptation
"Tsk tsk, every component can be connected. This small boiler can also hold water. Look at this small cylinder. Emma really paid attention to the details! The material of this base does not look like ordinary metal. It feels very similar to my golden gun!"

Xu Nian raised his head and looked at Li Han, "Is this base made of gold?"

Li Han nodded and said, "That's right."

"You are really extravagant. This base is actually made of gold. Wow, rich people play with flowers." Xu Nian sighed.

"It was given to me by someone else." Li Han said casually, "I don't have the time to build a model."

"A gift?" Xu Nian's eyes suddenly widened and he looked Li Han up and down with surprise in his eyes.

"Fuck! Brother, your classical architecture model worth hundreds of millions was given to you by someone else, your golden gun was also given to you by someone else, and this steam engine model was also given to you by someone else. In fact, your real identity is a prince who is experiencing life among the common people, right?"

"Get out! You are the prince, your whole family is princes!" Li Han said angrily.

Xu Nian did not continue to speak, but looked at the steam engine model carefully, and then could not help but said: "Long Yu Tian Ji Furnace, what a good thing, what a name, Steam Cultivation Immortality?"

Suddenly he slapped his thigh and said, "This is not a model, this is a miniature steam engine!"

"You mean, this thing can also boil water?" Li Han was also surprised by Xu Nian's words.

"Not only can we boil water, we can also make hot pot!" Xu Nian asked with some anticipation: "How about trying it?"

"Will the base be burned?" Li Han asked worriedly.

"Are you stupid? Can you please have some common sense?" Xu Nian looked at Li Han with contempt.

"The melting point of gold is 1063 degrees Celsius, while the melting point of a steam engine, even a high-pressure one, is only about 540 degrees. Are you afraid of burning the base? You are underestimating gold."

They got to work right away. Li Han found some coal, and Xu Nian filled the water tank with water. Then the two of them took a lot of effort to finally burn the coal.

After a while, the water boiled, and with a shrill whistle, the boiler transmitted the compressed steam to the connecting shaft, and the entire steam engine started to run.

The two grown men surrounded the steam engine as if they were looking at their favorite toy, with surprise in their eyes.

"What a masterpiece!" Xu Nian couldn't help but exclaim in admiration.

"Lao Xu, do you think this steam engine can be used as a power source for a steam locomotive?" Li Han asked suddenly.

"Yes, in fact, this steam engine is much better than the steam engine of the world's first train, 'Travel'. We just need to strengthen the connecting shaft and the gears, and then increase the pressure on the boiler. Of course, to build a real locomotive steam engine, it is not a simple enlargement..."

Suddenly, Xu Nian had a bad feeling in his heart, and he seemed to wake up. He stared at Li Han and said:
"Okay, Lao Li, I didn't expect you to be waiting for me here. We are brothers in this life, and this is how you schemed against me!"

"What's the scheming? It sounds bad to say that. We've been brothers for life. If you don't help me, who will?" Li Han said with a smile.

"I can't, I really can't, brother, I make guns, not trains!"

Xu Nian was about to collapse. Ever since his brother started writing novels, he felt that his workload was increasing day by day, and he was almost becoming an all-rounder.

"Doesn't your school have a locomotive major?" Li Han asked.

"What's the matter with locomotive or not? That's rail transit. Do you understand rail transit? They are two completely different things!" Xu Nian was about to shout.

"Isn't rail transit used for running trains?" Li Han asked innocently.

"You're the one talking nonsense!" Xu Nian looked defeated by you, "It's so hard to explain to an outsider like you!"

Li Han pointed at the model of the steam engine and smiled slightly, but to Xu Nian, this smile was like a devil tempting him. "Do you want it?"

Xu Nian really wanted to cover his ears so as not to hear every word Li Han said, but the three words "Do you want it?", like the devil's whisper, drilled into his mind without reservation.

So he couldn't help but nodded, "I want it!"

As soon as he opened his mouth, he criticized himself harshly in his heart. He was so disappointing that he completely fell for the little temptation.

However, he really wants this steam engine model!

"If you can help me get a set of steam locomotive manufacturing drawings, as well as the process of rail manufacturing and laying, I will give you a model."

In Xu Nian's eyes, Li Han at this moment was like the devil in Western religious stories, tempting him to make some kind of deal that would put him in an irretrievable situation.

But it was a deal he couldn't refuse.

Xu Nian touched his chin, thought for a while and said, "If you ask me to design a steam locomotive myself, I really can't do it. This thing is completely different from firearms. But our school library should have information on steam locomotives, eh!"

He suddenly clapped his hands and said, "A buddy of mine from my university dormitory has become a teacher at the Railway Institute of Central South University. Their school has a lot of historical materials about trains. It seems that there are also copies of the design drawings of the Beijing-Zhangjiakou Railway built by Zhan Tianyou, which are displayed in the school history museum!"

As he spoke, he took out his cell phone, found a number, and dialed it.

"Hey, Lao Si, it's me, your elder brother!"

"I'm still in Nanjing, not in Changsha yet. I need your help with something. Doesn't your school have Zhan Tianyou's railway design drawings? Can you help me get a copy?"

"A good brother of mine is a railway enthusiast and likes to collect these. Photocopies are fine, as long as they are detailed and clear. Okay, okay."

"Okay, it's settled. When you return to Nanjing, I'll take you to Qinhuai River to eat everything. What? Qinhuai River is a scam for tourists. Haha, kid, okay, I'll decide when you come back!"

"Done!" Xu Nian snapped his fingers, then looked at the steam engine model eagerly and said, "Can you give it to me now?"

"What are you thinking about?" Li Han said, "This is mine. I'll ask my friend to make another one for you."

Xu Nian immediately looked sad, "I have to wait again!"

"Heh, good food is never too late. What's the big deal about waiting a few days? How about getting you a signature model?"

"Okay, okay!" Xu Nian immediately changed his expression.

Once motivated, Xu Nian became active and left soon. He was going back to school to find teachers and information, and then design a feasible steam locomotive.

After seeing Xu Nian off, Li Han also spread out the letter paper and began to write back to Zhu Yuanzhang. He had to explain Brahmanism to Zhu Yuanzhang in detail so that the Ming Dynasty could carry out the next move.

A week later, Xu Nian sent the design drawings of the steam locomotive and Zhan Tianyou's railway design drawings. After seeing them, Li Han couldn't help but marvel at them.

Xu Nian designed a steam locomotive. The steam engine he used was the model that Lao Zhu gave him, but it was improved in many places to adapt to the long-term operation of the train.

The railway track design drawings by Zhan Tianyou made him intuitively feel the great wisdom of the first person in China's railways.

Li Han had learned about the zigzag railway in his middle school textbooks. After seeing it firsthand today, he was amazed by his ingenious design.

He collected the information and letters together, put them in the mailbox, and sent them to Zhu Yuanzhang.
