The eldest son is fierce

After chatting with Emperor Yanwen, Tang Yi went directly to the Craftsmen's Supervisory Office.

His job is done. Now it is the Jinyiwei's job to search homes and arrest people, and it is the Sansi's job to try cases. If there are any problems that cannot be solved, then report to the dog emperor.

Anyway, he only wants to make 98k now. He is very anxious because he can't make 98k!

As long as this powerful weapon is created, he won't have to be so cautious, and he won't have to worry about a Grandmaster suddenly appearing during a battle.

Otherwise, even though he is training new recruits now and seems to be very excited and confident, if he really encounters a master at the grandmaster level, it will only take two moves for him to defeat five thousand soldiers.

Unless everyone is equipped with AKs and has unlimited ammunition, they can resist a master-level expert. But the cost... even if Da Yan empties his treasury, he still can't produce that many.

An hour later, Tang Yi arrived at the Craftsman's Office, located deep in the Nanshan Mountains. This was originally a secret granary. During the Jingkang Incident, several mountains were almost hollowed out to store grain.

Now after renovation, it has become Dayan’s first secret arsenal.

Everyone thought that the emperor had deployed 30,000 troops outside the city to support Di Cang, so he sent them to the outside of the south city. However, no one knew that these 30,000 troops were actually deployed to protect the arsenal.

"Boy, you're finally here. Come on, come and see what the problem is."

As soon as Tang Yi entered the workshop, old Prince Fu came over quickly and pulled him deeper.

At this time, the old Prince Fu had disheveled hair, was covered in dirt and looked miserable, with even bloodshot eyes, but he looked as if he had been injected with chicken blood, and was extremely excited.

"Uh, Your Majesty, how long have you not slept?"

Tang Yi pulled the old Prince Fu and said helplessly, "This is not the way to fight for your life. You are already old, why do this..."

"You are old, your whole family is old."

When the old Prince Fu heard Tang Yi say that he was old, he was unhappy: "Boy, I have finally found something meaningful to do now. If you dare to curse me again, I will chop you to death."

Tang Yi was speechless. Do you know that I am concerned about your health?

You are almost sixty years old, and you are working at such a high intensity. Aren’t you afraid of sudden death?

He was taken into another forging room by Old Prince Fu, and the sound of blacksmithing came to his ears. Tang Yi stopped and looked in the direction of the sound, only to see dozens of workers hammering on gun barrels, causing sparks to fly everywhere.

There are no machine tools, all parts are made by hand.

"These are the top craftsmen in Da Yan. Wei Yuan found them all around the world."

Old Prince Fu pulled Tang Yi to a forging table not far away, picked up a steel pipe and handed it to Tang Yi, saying, "This is a barely qualified gun barrel, but how do you carve the rifling?"

"The most important thing is the rifling. How do you carve it?"

Tang Yi was stunned for a moment, raised his hand and patted his head, saying speechlessly: "Apologies, I forgot about this. The carving of rifling is very simple. You know the three-pointed arrowheads used by the Imperial Guards, right? Forge the three-pointed arrowheads used by the Imperial Guards, but don't make the arrowheads straight, but into a spiral shape."

"Then, drive the spiral arrow into the gun barrel, place a thin iron rod against the back of the arrow, and gently tap it with a hammer to force the arrow through the gun barrel."

When Old Prince Fu heard this, he jumped up on the spot: "Yes! Such a simple question, why didn't we think of it?"

"Boy, you are a genius, haha..."

Old Prince Fu suddenly realized that the barrel was difficult to hit, so they worked together to hit it one hammer at a time, but the rifling problem had troubled them for many days.

They even planned to find Ning Chuan, the eighth best person in the world, to try and use his true Qi to see if he could carve out the rifling.

But Ning Chuan was busy. Every day he was either catching people or on his way to catch people. The rest of his time was spent with Tang Yi. He had no time to come to the Craftsman Supervisor, and they could not take the gun barrel out.

This is top secret and no accidents can happen.

As a result, Tang Yi easily solved the problem that had kept them awake all night.

Tang Yi was speechless. Is this what you call a genius? If you had seen my experiments, wouldn't you have knelt down and regarded me as a god?

"Your Majesty, please help me find a few sets of parts. I want to try to assemble them."

Tang Yi was eager to try it out. 98k, I haven’t touched it for a long time, my hands are itching!

"How many more sets? What are you thinking of?"

Prince Fu glared at him and pointed at the craftsmen in the workshop, saying, "Do you know how much silver and materials we spent this month to make this master-level killing weapon?"

"Five hundred thousand, a full five hundred thousand taels!"

"That's not all. Just to make a small trigger, it's already driven more than a dozen craftsmen crazy."

"How many more fights do you want? Bah!"

Tang Yi was shocked when he heard this. "Fuck, is this so difficult? When I was in the army, it only took me an hour or two to modify a gun..."

Well, at that time there were machines and ready-made materials, so assembly was naturally fast.

But now, there are no cutting machines or grinders. Everything is made by hand. There is not even any professional measuring equipment. They still use the ruler he made...

And the cost is really outrageous.

Now we haven’t even produced a complete set of parts, but it has already cost 500,000 taels. If we can produce it, it will cost several million taels, right?

A Grandmaster killing weapon would cost nearly a year's worth of Da Yan's tax revenue!

Tang Yi felt a toothache at the thought of this. The Great Yan could not sustain this. If it were not for the many nobles and corrupt officials that had been dealt with during this period, Emperor Yanwen would have sent the Jinyiwei to pretend to be thieves and rob the whole world by now.

Damn, if I want to mass-produce AKs, how long will it take?

"Don't even think about assembly yet. Go over the construction of each part. If you have any questions or ideas, just tell me."

Old Prince Fu raised his hand and patted Tang Yi on the shoulder, saying, "Kid, the Grandmaster's killing weapon is depending on you."

Tang Yi saw that almost everyone was looking at him at this moment, so he could only shrug helplessly and said, "Okay, let me take a look..."

Damn it, I couldn’t wait to touch the gun, but not only did I not get it, I also had to do hard labor!

……

At night, in an inn in the north of the city.

Nangong Yue was sitting at the table, reading a book under candlelight.

At this moment, the door was pushed open, and the Prince of Zhennan walked in from outside with his hands behind his back. He smiled and said, "Mr. Nangong is really in a good mood. Now that the capital of Dayan is in turmoil, you can still read quietly like this."

Nangong Yue looked up at the Prince of Zhennan and chuckled, "I am not in a hurry. It is the prince who is in a hurry now."

"The prince wants to return to the southern border. Now is the best opportunity, but I don't know the conditions..."

The Prince of Zhennan stood at the window, looking at the street he was about to cross and sneered, "The conditions remain the same. I will return to the southern border and immediately withdraw the troops from Tengcheng and Kuncheng. Is that sincere enough?"

"However, before I leave, I must leave Tang Yi with a gift he will never forget!"
