The Red Mansion Big Liar.

Chapter 531 Sincerely convinced
In the duty room.

Zhang Yunyi took a sip of tea, and raised his hand towards the teacup in front of Wang Hui, indicating that he didn't need to be restrained, and asked, "Are those craftsmen enough?"

Wang Hui picked up the teacup and replied, "That's enough. It's not mass production. We're just making one or two samples. We don't need too many people."

“Is it easy to use?”

Wang Hui took a sip of hot tea, adjusted the lid of the cup in his hand, and said, "They are all experienced, and the students have brainstormed together, so the students have benefited a lot!"

Seeing that Wang Hui was not greedy for credit and was quite humble, Zhang Yun逸 secretly admired him, saying that it was indeed a true reputation.

He nodded approvingly and said, "I just found a few small problems. I will make some improvements later and then present them to His Majesty to commend you!"

After just a few laps, Wang Hui could see the problem. There were still several problems. He was in awe and put down his teacup, saying, "Please give me some advice, sir!"

"It's not about giving advice, it's about discussing with each other."

Zhang Yunyi said modestly, "The pedal needs to be improved a little bit. Otherwise, the speed of the pedal must be consistent with the speed of the car, which is not only inconvenient, but also easy to hurt people and the connection is also easy to damage..."

Wang Hui's eyes lit up, and he immediately stood up from his seat, bowed and said, "Does your Excellency have any good ideas?"

"Don't be in a hurry!" Zhang Yunyi raised his hand and pressed down, indicating Wang Hui to sit down, and then said without comment, "In addition, we need to add another mechanism to the handle of the dragon head to facilitate braking."

Wang Hui was stunned at first, then he seemed to be thinking about something.

Although he is good at using strange weapons, he cannot avoid preconceived ideas.

Ancient horse-drawn carriages did not have brakes, so it was no problem to drive slowly, but if they stopped, there would be no power. If they wanted to drive fast, they would need to slow down the horse first, which was one of the values ​​of the coachman.

Therefore, Wang Hui ignored this part, but Zhang Yun逸’s words woke him up.

"Although the wood you chose is good, there may be other materials for the wheels. I heard that there is something called rubber overseas. I sent people to find some by sea a while ago. Perhaps we can give it a try."

How could Zhang Yun逸 not pay attention to such a good thing as rubber?
The Great Xia Dynasty had many vassal states, and the Wang family was in charge of tribute affairs in the early years. As early as when he was digging bird droppings, he asked people to pay attention and inquire about it, and he only got a batch not long ago.

"Thank you for your advice, sir!"

Zhang Yunyi shook his head and said, "It's not like I can give you any pointers. If you ride it for a couple of laps, you'll naturally be able to find the problem."

Wang Hui asked again: "Do you have any good ideas for pedals and wheels?"

Zhang Yunyi was clear about the brakes, but as for the pedal, he only knew that it had a great relationship with the steel balls between the axles, but he only had a vague understanding of the details.

He did not show any fear, but instead acted confident and said with a smile: "If I were to give you advice on everything, wouldn't that go against the original intention of establishing the Immortal School? These two items are test questions. You can use them to test your students later, so that everyone can brainstorm and discover talents at the same time!"

Wang Hui was startled when he heard this, and said respectfully, "Yes! I am grateful for your advice!"

Zhang Yunyi asked about the progress of the spinning machine again, and Fang said, "There is one more thing right now that requires your attention."

"My Lord has ordered!"

"The Railway Guard has been training for several months, but Li Congwen has been making things difficult for us. The firearms have not been improved yet, and I have found that the firearms have many shortcomings. I have asked the emperor for instructions to improve them on my own."

He came today not only to inspect the bicycles, but also to improve the firearms.

"Firearms? They can't stand moisture, are difficult to load, and are not as accurate or as far as arrows..."

Zhang Yunyi raised his hand to interrupt, "What you said makes sense, and that's why we need to improve it. Although firearms have many drawbacks at present, what if these problems are solved?"

Without waiting for Wang Hui's response, he spoke eloquently, "Human power is limited. Even the most well-trained archers will become exhausted after shooting a dozen arrows. On the other hand, firearms can attack continuously as long as the barrel does not explode, and the difficulty of training is incomparable."

"Your Excellency is right!" Wang Hui nodded, but then he changed the subject and said with difficulty, "Although I have seen this thing at my cousin's place, I have no clue..."

As a fifth-rank garrison commander, Zhang Songyuan had also come into contact with firearms. Zhang Yunyi had also heard about this during their conversation with Wang Hui. Zhang Yunyi smiled and said, "It's okay. It takes time to get used to it. I can point out the general direction, but you have to figure out the specific improvement methods."

"Please speak, sir!" Hearing that Zhang Yunyi could point out the direction, Wang Hui gained some confidence.

"First of all, the rate of fire of firearms is mainly due to the difficulty of loading. What if the powder is loaded in advance and ignited with flint? You have seen firecrackers, especially the double-kick firecrackers. You might as well think more about this aspect..."

Unlike his explanation of bicycles, this time Zhang Yunyi went into great detail and even simply drew the shape of a bullet.

"As for materials, Xianxue has also produced some improved refined iron, and we can choose a heat-resistant ratio... In addition, the inside of the gun barrel must be engraved with rifling..."

"Rifling? What is rifling?" Wang Hui asked puzzledly.

"It's the curve inside the barrel!" Zhang Yunyi pondered for a moment, pointed at the bullet in the picture, and added, "It can make the wrapped bullet fly out of the barrel in a spiral."

Wang Hui glanced at the end of the bullet that Zhang Yunyi had scribbled on the paper, and said thoughtfully, "The student understands!"

He then wondered again: "But what's the use of this?"

"Have you ever played with a spinning top?"

Wang Hui was stunned for a moment, then his eyes flashed with a gleam of light, and he exclaimed as if waking up from a dream: "Student understands! The faster the speed, the longer it lasts..."

He said sincerely, "The truth is simple. You are indeed a genius. I admire you!"

Talking to smart people saves effort.

Seeing that Wang Hui understood, Zhang Yunyi said, "There is one more thing I need to ask you, sir."

"My Lord has ordered!"

"You also know that I have some disagreements with Li Congwen, and he has also hindered me in many ways. Firearms are just one of them. The officers of the Railway Guard have never been transferred. You also know that firearms are quite unpopular, and there are not many generals who are familiar with them. Last time I heard you mention that your cousin Zhang Songyuan has dabbled in firearms..."

At this point, he paused and said, "When that happens, can you help talk to your cousin and ask him to join the Railway Guard as a general?"

Because of Li Congwen's obstruction, the Railway Guard is in a bit of an awkward situation and no general officers have been dispatched yet.

However, this also gave Zhang Yun逸 an opportunity to take action.

On the one hand, as he said, the operation and tactics of firearms are different from those of cold weapons.

On the other hand, I want to find a reliable candidate.

He was preparing for a rainy day. After all, even if he was willing, he might not be able to pass the test of Li Congwen.

But once he reported the affairs of Li Congwen's son to the emperor, I'm afraid he might not be able to continue his job as the Minister of War.

Originally, Zhang Songyuan had no right to object to this operation, but he was a fifth-rank garrison officer after all, and the railway guard team had only two or three thousand people, only half of the garrison troops.

Naturally, we have to do some work first to make Zhang Songyuan willing, so as to avoid making things worse.

Wang Hui hurriedly said, "Your Excellency is too kind! Your Excellency is willing to break up with Li Congwen in order to uphold justice. My family is deeply grateful, so how can I not be grateful?"

Zhang Yunyi nodded and added, "Don't worry! Although the Railway Guard currently only has half of its troops on duty, it only covers this section of the Beijing-Tianjin Railway. When the railway is laid out in the future, I promise that I will not let your cousin down!"

Although we often make promises, this time it is not the case.

The Railway Guard Corps was the only military power in his hands, so how could he not do everything he could to expand it?
