"Your Majesty, we are all our own family. If I'm polite, I'm not going to be with you." Gu Qing looked at Li Tai again while eating tea eggs, "Fatty, do you think so?"

Hearing the title of fat man, Li Tai turned his head and didn't want to pay attention to Gu Qing.

"I know everything." Li Er casually peeled the tea egg, "Tell me, what's the wonder of this engine?"

Gu Qing said, "In fact, there is not much wonder, it can replace a lot of manpower."

"Are there any more." Li Er said knowingly, "I heard Qingque say that this thing can change the times, right?"

"It's too early to say that the times change." Gu Qing.

"Oh?" Li Er was puzzled, "How to start?"

"The engine today is just a prototype, and it needs to be built. With this prototype engine, it can continue to develop. The more perfect the engine, its efficiency and stability will be better. As long as the engine is perfected successfully, let alone the Thousand Mile Horse. Thousand Mile Raiders and Marches are all day and night."

Speaking of this, Li Er's expression was a little strange.

Gu Qing quickly explained, "Don't worry, Your Majesty, this will be built several years later. With the current craftsmanship of the Tang Dynasty, it still cannot reach the level I mentioned."

"After the prototype is in its shape, it will be a matter of time sooner or later." Li Er's expression was extremely strange.

"It's not as simple as imagined." Gu Qing waved his hand, "craftsmanship! The process I'm talking about is a process on metal. You must start with the most basic steelmaking. Your Majesty also knows that the steelmaking technology of Datang is really not good now, because the higher the operating frequency of the engine, the higher the steel strength required. According to the current Datang process, the engine efficiency produced is not much different from the efficiency of a donkey, let alone traveling thousands of miles a day. Only by doing a good job of steelmaking can you do better. Of course, steelmaking is the foundation in the foundation, and the process on the upwards can be explained clearly. I don't understand the specific situation very well, and I need to explore it."

"Gu Qing." Li Er looked at Gu Qing and said, "This engine needs control. You know how important the marching speed is in marching and fighting."

"Of course I understand. Your Majesty, don't worry, I will watch it." Gu Qing said.

"My son will watch it too." Li Tai also said.

"That's good." Li Er stood up, "I have eaten enough, you guys can make it well."

"My son and I will send you my father to the emperor." Li Tai followed Li Er out, but was persuaded by Li Er to come back.

When Li Tai turned around, he saw Gu Qing still peeling the tea egg leisurely and looked anxious, "Did you listen to the words of Father?"

"Listen." Gu Qing packed the eggshells, "Your father meant that he didn't want the engine technology to fall into the hands of others. Now he was worried that this was still a long time ago, what your father and I told the truth is. According to the current Tang Dynasty craftsmanship, we cannot do what I said, and we must do the basic steelmaking well."

When Li Tai heard about steelmaking, he had no choice but to do anything, "Gu Qing, just like the watch and pistol you gave me, these crafts are something that the Tang Dynasty cannot do now, right?"

"That's right." Gu Qing nodded, "But I have also made a similar firearm. Musket. Although the accuracy is not as good as a pistol, it will become a weapon like a pistol as it improves. Everything is in the word "craftsmanship", and both industrial level and craftsmanship must be improved."

I am increasingly confused about Gu Qing's origin. I have almost forgotten Gu Qing's origin. Now I mention it again. Li Tai is very afraid of where Gu Qing's hometown comes from. Since the founding of the Tang Dynasty for more than 20 years, I have no such fear in the face of Turks and Tubo.

The things Gu Qing brought gave him too much shock, from the knowledge in the academy to the things that Gu Qing took out, all of which subverted the cognitive level.

"Gu Qing, where is your hometown?" Li Tai whispered, "I'm starting to be scared now."

"What are you afraid of?"

Li Tai said, "Everything is as you said. If there is such a craft in this world, your hometown is already so powerful. Today's Tang Dynasty is a drop in the ocean in front of your hometown. I feel a sense of powerlessness in my heart."

"You will meet my hometown, and that was a very good era." Gu Qing said to Li Tai, "If you wait for a longer life, maybe we can see it."

"Is that true?" Li Tai smiled bitterly.

Li Tai felt inexplicably sad, standing in front of Gu Qing. The Tang Dynasty has indeed become powerful over the years, and all countries in all directions surrendered to the feet of the Tang Dynasty. If Gu Qing's hometown comes to the Central Plains, would it be a disaster? No matter how hard the Tang Dynasty works, how it develops, or how it becomes stronger, it will be destroyed by the legendary hometown. So what is the meaning of all efforts?

"Why are you looking at me?" Gu Qing said after packing up the egg shells.

"Nothing." Li Tai put away his thoughts, "Do you have any other direction to point out the engine construction?"

"Steelmaking is steelmaking!" Gu Qing emphasized, "If you take out steel with sufficient hardness, you can increase power and stability, which is very important for the engine."

"Your idea is very vague," Li Tai said, "It's like making steel, what kind of steel should be refined."

"Now the hardness of the horizontal knife is twice as hard as that," Gu Qing said, "Maybe the blacksmith can understand this. Most of the steel is forged now, and the efficiency of this kind of steelmaking is too low. You can think about what to do next from this perspective."

"I know it in my heart." Li Tai nodded.

Li Tai's eyes were still a little wrong, "Don't look at me like this, just say anything directly."

"Okay." Li Tai sat next to Gu Qing and blocked his shoulders and said, "I know, there must be a lot of good things in your stomach that have not been poured out yet, right? Hurry up! Pour out all the things in your stomach, and let the students in the academy work hard one by one."

"It's gone, I can't fall out." Gu Qing said.

"real?"

"real!"

"Why am I so unbeliever?" Li Tai looked at Gu Qing, "You really have nothing in your stomach?"

"What am I lying to you?" Gu Qing stood up leisurely, "You know what I can say."

"Oh." Li Tai nodded suspiciously.

"By the way." Gu Qing came to his senses, "There is a kind of train thing that can take hundreds of people far away, and it is also very fast."

"Train?" Li Tai was in a state of mind, "I knew you must have goods in your stomach, hurry up! Tell me, I will write it down with my pen and ink."

"But what..."

"What's wrong!?"
