gratefully gave Yao Guangxiao a reassuring look, and Tang Ming replied to Zhu Di with a confident face: "Emperor Xie has given convenience to the ministers, and the ministers should do their best to complete this matter and solve the worries in the emperor's heart." ”

"Hahaha, okay, young people should have such courage, Sanbao will take you to the Superintendent to find someone, if you still need anything, I will satisfy you." swept away the haze just now, and Zhu Di actually laughed.

Bidding farewell to Zhu Di, Tang Ming followed Zheng He out of the palace and went straight to the Governor, Lingyi and Xiaobai, who were waiting at the palace gate, had already prepared a carriage and were waiting. Xiaobai was very sticky to Tang Ming, and when he saw him, he immediately pounced on him and licked his saliva before giving up. Tang Ming recently found that Xiao Bai wanted to be a dog more and more, since leaving the wolf pack, Xiao Bai's wolf nature seemed to have weakened a lot, and even the barking began to bark from time to time.

Nanjing Supervision Division is located in the north of the city, away from the noise of the city center, less of all kinds of shouting, but more of all kinds of banging sounds. Under the Supervision and Manufacturing Division, there is an Ordnance Bureau, which is in charge of the manufacture of cold weapons, and a War Bureau, which is in charge of hot weapons and guns.

Of course, the talent that Tang Ming needed this time was to find a more suitable one in the War Bureau, and as soon as he got out of the carriage, he saw two officials waiting at the door of the Supervision Division. The two of them are the left and right attendants of the Supervision Division, and Yang Qing, the left attendant, is about thirty years old, with a thin face, a goatee, and bright eyes, giving the impression that he is shrewd.

The right attendant Lang Tiexiong looked much younger, with a tall figure, very dark skin, a pair of thick palms full of calluses, and a black face that did not need to look very honest, Tang Ming understood that this person should be doing manual work when he saw him for the first time. Especially his arms now, which were covered with black ash, it was not difficult to imagine that he must have been doing something by the fire just now.

When the two saw Zheng He get out of the car, they stepped forward and saluted: "My lord, all the people are gathered in the courtyard, please come with us." ”

Nodding, Zheng He called Tang Ming to follow the two into the gate of the Supervision Division, while Lingyi and Xiaobai were waiting at the door together, he was not qualified to enter the Supervision Division without an official status. It doesn't seem like much here from the outside? But the strictness of the precautions inside is frightening.

Needless to say, ten steps and one post, five steps and one sentry, these are only on the surface, and there are still many archers in ambush in the dark. The Supervision Department can be said to be the most advanced place in the entire Daming Science and Technology, and Zhu Di is also very concerned about these, so it is natural for this place to become an important place.

The interior of the Supervision Division is divided into two places, one side is the Weapons Bureau on the left, and the right is the War Bureau. Only the right attendant Lang Tiexiong took Zheng He and Tang Ming into the courtyard of the War Bureau, and as soon as he entered the door, there were more than a dozen men who had a fight with Tiexiong.

Tie Xiong pointed at them, and said to Zheng He angrily: "My lord, the best wrought iron and blacksmith hands in the War Bureau are here, if you have any questions, they will tell them frankly." ”

Zheng He smiled when he heard this, pulled Tang Mingyan and said, "Tiexiong! It's not that I have any problems coming to you this time, but my righteous son Tang Ming, who has just been named Weihai Hou by the emperor, and if he has any difficulties, please help me. ”

He glanced at Tang Ming in surprise, seeing that he was named Weihaihou by the emperor at a young age, although he didn't know what level this Weihaihou was, but now he could not be despised by the emperor. Tie Xiong took a step forward and saluted Tang Ming: "I don't know if Weihai is waiting for the arrival, I hope the Hou Ye will forgive me for the rudeness of the right waiter Tiexiong." ”

Just from the tone of Zheng He's conversation with Tie Xiong just now, Tang Ming had already guessed that the two must be very familiar, and then looking at Tie Xiong's black and gray clothes, such a person must be a practical official, no matter what his character is, at least he got a good impression on Tang Ming.

"Uncle Tie is too polite, what is the Hou Ye or not the Hou Ye is uncomfortable to listen to, if you don't mind, just call Gongzi." Tang Ming knew very well that people like Tie Xiong liked to be cheerful, otherwise you couldn't see that the disobedient expression on his dark face when he saluted himself just now was from the heart.

Tie Xiong suddenly laughed when he heard this, changed his appearance just now, patted Tang Ming's shoulder heavily, and smiled: "You kid I like it, it's refreshing." If there is anything you don't understand, just ask, if they dare to hide their secrets, Lao Tzu will be the first to spare him. ”

Tie Xiong's palm was like an iron pan, and it was extremely powerful, and he almost killed Tang Ming's half life when he patted his shoulder just now. Endured his sore shoulders, pretended to be grateful, and thanked Tie Xiong again and again for his kindness.

As soon as he said that, things were naturally much easier, Tang Ming proposed to go to the place where they wrought iron to watch the scene, and Tie Xiong didn't say much and immediately led the way in front. The War Bureau specializes in the manufacture of muskets and artillery, and naturally gunpowder is also manufactured, but the wrought iron and gunpowder are very separated.

Gunpowder Tang Ming didn't look at it, the black powder at this time was not mature enough, and the power was also insufficient, the most important thing in front of him was to solve the treasure ship keel first, and as for the gunpowder, he could do it on his own island in the future.

The wrought-iron stoves were all in the open air, lined up in a zigzag, and there were more than two dozen stoves at a glance, emitting an astonishing heat, and the long flames erupted out of the furnaces, constantly beating. Tang Mingren hadn't approached yet, and he was already sweating profusely. He took off his soft armor and leaned forward to watch.

Coal is burned in the furnaces, and each of the two furnaces has a manual blower to fuel them, so that the temperature can reach even higher. This made Tang Ming's eyes light up, and he was very satisfied with such a technology. turned around and asked Tie Xiong: "Uncle Tie, how much is the current output of our Ming Dynasty, and how do you get it when you weld?" ”

Tie Xiong's eyes were full of brilliance when he heard this, and the child in front of him seemed to be an expert in this area, and he could actually know how to weld. Putting away the contempt in his heart, Tie Xiong explained seriously: "We divide welding into three types, generally copper welding, then silver welding, and welding like building artillery, which is directly poured with molten iron, and when it needs to be finished, it is repaired by copper welding. ”

In order to let Tang Ming understand directly, Tie Xiong directly pulled him to the place where the cannon barrel was welded after speaking. After watching it, Tang Ming simply went down to test the welded artillery mount in person, and after watching it carefully, he saw that the welding was perfect. In order to test the hardness of the weld, he also asked someone to try to smash it with a sledgehammer, and he was very satisfied.

This welding technology is already comparable to the household electric welding of later generations, although the process is cumbersome, but it is still within the acceptable range.
