Li Chengqian knew Feng Ang’s purpose very well. When the old man asked him anxiously, he said bluntly: “Father, he just wants a ship, but now I am not even equipped with the main fleet, so why give it to him!”

Li Er had no idea about new ships at the beginning, so he naturally couldn't figure out Feng Ang's intentions, so he asked Li Chengqian to come and ask.

Now that everything is on the table, he naturally has his way of dealing with it. He just waved his hand to the questions raised by Li Chengqian and signaled that he didn't have to worry about it.

"What are you tinkering with recently?" After putting Feng Ang's affairs aside, Li Er continued to toss his son.

As long as the boat is not mentioned, Li Chengqian will answer questions and ask questions. The things that are being tinkered with by the people now will also be equipped with the Sixteen Guards in the future. They will tell Li Er early or later. Now that the old man asked, Comrade Li went downstairs and said, "I'm going to try it out in the past two days.

"What is a trench car? Tell me carefully." Li Er was very interested whenever he heard something related to war, so when Li Chengqian mentioned it, he became energetic.

"Father, why don't we go and have a look? This thing is just a matter of saying."

"It's true, there's nothing wrong today, so I'll follow you to take a look." Li Er calculated the time and nodded in agreement with Li Chengqian's arrangement.

The next time is to wait for the old man to change his clothes and recruit people.

Unlike Li Chengqian, he is just a prince. It is enough to go out to bring Ye Mei and a few others to guard him. However, Li Er's goal is too big. If he wants to go out, someone must first clean up the scene or be alerted, and then he will officially go out. Even if he goes out with a white fish and dragon suit, he must arrange the guards in advance.

Half an hour later, Li Er, dressed in casual clothes, came out of the back hall and pulled the somewhat bored palace of Li Chengqian.

"Well? When did Changle come? Why didn't you see anyone?" As soon as he left the old man's study, Li Er couldn't help but feel a little surprised when he saw Changle's bicycle parked outside.

"Father, I rode this here." Li Chengqian said a little embarrassedly.

Changle's car is a woman's style and is decorated very beautifully by the little girl. Now I don't ride the decorations but have not taken them off. If Li Chengqian rides it, he will look a bit sissy.

"I just said why are you here so quickly today..." Li Er turned around and glared at Li Chengqian, feeling helpless about his behavior of taking advantage of loopholes.

But as me, how could Li Er have no choice but to do his son?

So, on the way to travel, there was a scene where Li Chengqian struggled to ride a bicycle and followed the old man's carriage. Perhaps this was the end of being clever.

Fortunately, the prison is in the imperial city, and it will not take long to get out of Tai Chi Palace, otherwise Li Chengqian would have to vomit blood so tired.

"My memory, Liu Min, has seen His Majesty, and His Royal Highness the Crown Prince." Facing Li Er's sudden arrival, Old Man Liu seemed a little nervous. After all, no matter how high the old man is, he cannot change the fact that he is a craftsman leader.

"Plain, I heard from the prince that you will be a prisoner and are trying to produce an ordnance that can quickly pass through the trenches and moats, so come and take a look, don't be nervous." Li Er also knew that his imperial guards had great psychological pressure on the following ministers who were not often met, and he explained his purpose directly with great understanding.

"Your Majesty, that's a trench cart, developed by His Royal Highness the Crown Prince. He will not dare to take credit for his work as a prisoner!" Li Chengqian was standing next to him, and Liu Min didn't dare to take all the credit directly on him.

"Even if he develops it, he will make a contribution to the supervisor. I am not confused yet. If you have any contribution, you will make a contribution." No matter what, Li Er still affirmed the contribution of the supervisor, paused for a moment and asked, "Is this trench cart physical?"

"When you go back to your Majesty, some are the physical objects of the trench carts in the backyard, but if you want to test, you need to go outside the city." After a period of buffering, Liu Min's nervous mood relaxed a little, and answering questions began to be organized.

"Then let's go and have a look."

Li Er, who is old, is not comparable to those emperors who grew up in the deep palace. Whether an orbit is easy to use does not necessarily require the effect of the experiment. Many times, just look at the appearance and you will know whether it is practical in war.

After a while, under the guidance of Liu Min, Li Er and his party arrived at the backyard where they were about to be in charge. As soon as they entered the yard, they saw something similar to a ladder parked in the middle of the yard.

The reason why this thing like a ladder is called a car is because it has four wheels, but the two wheels in the front are particularly large and the two wheels in the back are particularly small.

Its support frame is an inclined inclined surface with a very thick board on it.

"That's it?" Li Er raised his hand and pointed.

"Back to Your Majesty, this is a trench car." Liu Min nodded.

"This thing..." Li Er walked to the side of the trench car, circled around it twice, then looked at Li Chengqian and Liu Min and said, "Do you want to push it directly into the moat? Right?"

"Father (Your Majesty) is wise!" Li Chengqian and Liu Min flattered not very big at the same time.

"How heavy is this thing? How many soldiers are needed to push it?" As the emperor became more and more years old, Li Er had become accustomed to this kind of flattery and asked without any reaction on the trench cart.

"The weight is about 2,000 kilograms, because bearings are added to the wheels, and it takes about five people to push them." Li Chengqian didn't understand this specific data, so the question was answered by Liu Min.

"Five people?" Li Er nodded: "Five people come and push them."

Practice is the only criterion for testing truth. Li Er will not say this, but he will do it.

Because just looking at the size of the trench cart, Li Er didn't believe that this thing could be pushed up by five people.

However, in the end, it turned out that if it was on the flat ground and without any obstacles, only three people could push the trench cart, but if you wanted speed and strength, five people were necessary.

"Not bad. It's really good." After verifying that the trench car could indeed be pushed and run by five people, Li Er was very satisfied. After walking around for two more times, he was attracted by another object in the yard.

"What is this?" Li Er asked after reaching a round iron pillar, about half a foot thick and about half a foot long, stretched out his legs and kicked it.

"This..." A hint of embarrassment flashed across Liu Min's face and she looked at Li Chengqian.

"What? Is there anything we can't say?" Li Er frowned and asked in a deep voice.

He hates all kinds of concealment from him the most. Of course, maybe he doesn't care that it's Lao Li, and any emperor seems to hate this.
