Chapter 113
"Zi'an, the time for building military weapons is tight. When can you go to the Military Intelligence Bureau to make a forging furnace?"
Tang He asked eagerly.
Then, he turned his head and looked at Zhu Yuanzhang again, his eyes flashing.
"Uncle Tang, should the forging furnace of the Military Equipment Bureau be more ordinary or better quality?"
Seeing Tang He's expression that he had something to say, Zhu Zi'an trembled and asked quickly.
Compared with the problem, except for Yang Siyi from the Ministry of Revenue, he is really not afraid of anyone!
“What’s the difference?”
Zhu Yuanzhang, Tang He and others were both stunned.
"On ordinary things, even those smelting furnaces in the Military Bureau have slow heating of the furnace temperature and the speed of smelting iron juice is also a bit slow."
Zhu Zi'an explained slowly, "If the quality is good, it is like the forging furnace in the factory in the outer city. Not only does the fire be heated quickly, the time for smelting iron juice is also shorter!"
"Of course, the biggest difference between the two is the difference in the speed of forging steel. Forging steel with better quality is as fast as that of ordinary forging furnaces.
Of course, this is also because the materials used to make forging furnaces are different. For example, the forging furnaces in the Military Bureau are only made of salt and clay.
However, the forging furnace in the factory outside Zi'an City is made of graphite and clay. It is much better than the forging furnace of the Military Bureau. It not only has a much higher thermal conductivity, but also has a much longer service life =!"
After Zhu Zi'an's series of words, Zhu Yuanzhang looked a little dull. His cultural level was not high. He was still in Yingtian City for many years and often read some books, which made Zhu Yuanzhang not very nervous when facing those civil officials.
However, this moment was a shock to Zhu Yuanzhang when he heard such a lot of words he had never heard of.
However, the most important problem among them is that Zhu Yuanzhang understood the materials for making the forging furnace, graphite.
"Zi'an, what kind of object is that graphite?"
"Back to the emperor, the graphite is a gray-black stone, very fire-resistant, and any flame in the world cannot burn it. The forging furnace made of graphite and clay, coupled with coking coal, is an excellent tool for forging steel!"
Zhu Zi'an replied.
“Coking coal?”
Seeing Zhu Yuanzhang's face showing a hint of doubt, Zhu Zi'an quickly explained: "Coking coal is to place the coal in the iron smelting furnace, and tightly isolate it from the outside air. Then, it is calcined in the forging furnace for an hour, and finally form a kind of combustible coal.
Moreover, coking coal burns faster than ordinary coal. It produces more heat!”
"I see!"
Zhu Yuanzhang nodded suddenly and turned his gaze to Tang He.
"Your Majesty, now, the military weapon bureau has started to use coking coal to forge steel!" Tang He replied.
“Use it?”
Zhu Yuanzhang was stunned for a moment, then smiled and turned his head to Zhu Zi'an.
"Zi'an, you haven't said yet, how long does it take to make the two forging furnaces?"
"Your Majesty, as long as the materials are complete, the time to make the forging furnace will be the same!" Zhu Zi'an said, "Zi'an can make two forging furnaces within seven days!"
"The graphite that Zi'an said seems to be in the military weapon bureau, and it is!"
At this time, Tang He thought of something and quickly bowed his hand and replied.
“…”
Zhu Yuanzhang was stunned again, was there graphite in the military weapon bureau?
As if he knew what Zhu Yuanzhang was thinking, Tang He hurriedly bowed and said, "Your Majesty, when Zi An went to the Military Weapon Bureau last time, he told the Military Weapon Bureau Ambassador Shang Yintie and others. Moreover, Shang Yintie had already asked someone to bring back bad graphite from Yiling Prefecture!
However, the craftsmen from the Military Weapon Bureau have made many forging furnaces using graphite tests, but they have not been successfully made!”
"There is still this?"
Zhu Yuanzhang continued to be stunned.
"Uncle Tang, this is not surprising. Although the process of making a forging furnace with graphite is similar to that of salt and clay. However, graphite is still different from salt, and it is difficult for ordinary people to make it successfully."
Zhu Zi'an smiled and said, "Since there is graphite in the Military Weapon Bureau, this matter is easy to deal with. Tomorrow, Zi'an will go to the Military Weapon Bureau!"
"So, thank you Zi'an!"
Tang He looked overjoyed.
With Zhu Zi'an's words, Tang He suddenly felt the pressure on himself and suddenly disappeared.
War is always a pitfall between weapons and intelligence!
Although the Yuan Dynasty was corrupt, it used an excellent military system with the power of a country.
Although Xu Da’s northern expedition was so smooth, it was also based on his iron-blooded morale, and he also fought and persuaded him to surrender.
Before the war began, the morale of the old Yuan was half diminished.
Otherwise, even if the Northern Expedition is successful, the Ming Dynasty will be greatly damaged!
Zhu Yuanzhang developed in Yingtian City for so many years before most of his army could make the army more military and military catching up with the old Yuan Dynasty.
However, in terms of military preparation, Tang He and the generals were worried.
Forging 20,000 steel knives and 10,000 steel guns within one month was a task assigned by Zhu Yuanzhang, and it was also a way for Tang He to check the strength of the Ming Dynasty Military Arts Bureau!
Afterwards, after arguing the time, Tang He hurried to the Military Weapon Bureau to prepare the supplies needed by Zhu Zi'an to make forging furnaces.
As for Zhu Yuanzhang, he had a little idea of having a free meal.
However, after seeing Zhu Zi'an's cautious expression, he smiled awkwardly, followed Tang He and headed towards the palace.
Why do real men worry about not having delicious food? Moreover, there are so many memorials in the palace that they need to be reviewed by themselves!
Afterwards, Zhu Biao and Tang Ding also said goodbye!
It just so happened that along the way, Zhu Biao could be carried by Tang Ding’s carriage to deliver vegetables!
The Prince-Consort’s Mansion!
Song Mansion!
After the two palaces were successfully delivered, Tang Ding had to continue to send him off. After sending Zhu Biao back to the palace, he went to Tang Mansion!
On Song Lian’s mansion!
"Master, is this the vegetables in the glass greenhouse outside the city?"
“That’s right!”
Song Lian stared at the table, the vegetables that the prince filial to him were from, his face changed and he nodded slowly.
"I heard that this morning, many housekeepers in the nobles' mansion went to the gate of the Xiaozhen Mansion to buy vegetables, but they didn't buy vegetables. Even the Shen family offered a sky-high price of 1 pound, but the little real man did not sell it. Unexpectedly, this afternoon, His Royal Highness the Crown Prince brought so many to the master!"
Looking at the half basket of vegetables on the table, the housekeeper looked surprised and excited, but he didn't notice the increasingly ugly face of his teacher.
After turning my head, I realized that something was wrong with my master.
His expression changed drastically.
"Master... Is there anything wrong with this?"
"Oh, nothing happened!"
Song Lian sighed heavily, waved his hand, and said, "Take the vegetables down and cook for the evening! Also, let me continue to give you instructions, no one is allowed to talk about this matter!"
"Yes, Master!"
The butler said quickly.
Then, he walked out with a solemn look on his face.
