Putting aside how Li Muyun regained his husband's leadership, he said that in Li Er's palace that day, several big men were gathering together and staring at an Eight-Nuo Crossbow in a daze.

The Baniu Crossbow has been hung with a crossbow string and is in a state that can be fired at any time. The thick crossbow gun pointed obliquely in the sky, which makes people feel creepy.

Li Jing turned around the Eight Niu Crossbow several times, and would touch it from time to time. Finally, he asked in confusion: "Your Majesty, there seems to be no problem with these Eight Years crossbows. I wonder what your intention is to bring it over?"

"Of course there is no problem with this crossbow, but it is also the biggest problem." Li Shimin pointed to the Baniu Crossbow and said: "It has been more than a hundred years. Since the former Sui Dynasty, this crossbow has been like this. Haven't you ever thought about changing this thing?"

"Change? This should be the matter of being a prisoner?" Chai Shao said while rubbing his chin.

Li Shimin nodded in agreement, and then threw out a booklet: "I really want to change it as a supervisor, but you'd better take a look at this first."

"What is this?" The booklet is not big or very thick. Chai Fuma took it over and gently opened it, and frowned immediately: "Improving the craftsmanship? Is this written by King Xiaoyao?"

"Who else can I have besides him? Some time ago he promised to sell cement to Goguryeo. I asked him how to solve the problem of Goguryeo building a city with cement, and he suggested that I improve my military."

Hou Junji was very popular and exploded at that time: "Improving the military equipment? It's really nonsense. These equipment have been used for dozens or hundreds of years, and there is no problem. He can change it in one sentence, which is that easy."

Li Shimin waved his hand and said disrespectfully: "You don't have to tell me this. When Mu Yun comes later, you can suppress him collectively."

Suppress him? Several old guys looked at each other. Can that guy who was unreasonable and disturbed three points be suppressed by ordinary people?

Just as he was thinking, the footsteps sounded outside, Li Muyun appeared in front of everyone in a teapot, dressed in casual clothes, and looked like he was out on an outing. He saw everyone, and said hello: "Oh, where are they all? Brother, I look so good today."

"Well, here we come!" Li Shimin glanced at his brother helplessly, pointed to his old subordinates and said, "Tell them your thoughts. If they all agree, follow your wishes, otherwise you will go back and stay for me honestly."

Li Muyun put the teapot in his hand on the Baniu Crossbow and said with confidence: "What's there to say? Brother, the times are progressing and society is developing. The military can't stagnate, right? The old thing that has been more than a hundred years ago has to change it."

"What the prince said is a bit exaggerated. As long as the things are easy to use, it's okay to change them all over the place."

"Yes, what if you get new weapons and equipment now, what should you do if these old things are done? You can't all be eliminated, right? It's all money!"

"There are currently no less than 5,000 Eight-Cow Crossbows in the country, let alone other siege and defensive equipment. These require a lot of money. King Xiaoyao, you won't be able to do these."

As the saying goes, one stone hits a thousand layers of waves. After Li Muyun finished speaking, he immediately attracted a counterattack from veterans. They all spoke harshly and looked like they wanted to eat people.

What Li Muyun looked down upon the most was these old guys who were not motivated. He said with his eyes: "So what if it costs money, it is necessary to do something like military equipment. If you don't do it, I won't do it. I'm afraid we are still using bows and arrows made of animal bones and spears made of stones."

"Even so, there is no need to replace everything as you said, right?" Li Jing didn't say anything, but stood up at this time.

Li Jing was neither close nor distant to Li Muyun, but he couldn't stand his "random" expressions and did not care about the consequences at all.

Fortunately, the latter did not want to have a good relationship with Li Jing. Seeing that he stood up and said without thinking, "The development of weapons is the fundamental driving force for social development. How can the country be guaranteed to be stable and united without good weapons? How to defend against foreign invasions without good weapons? The value of weapons is not measured by money, it also affects the people's trust in the country."

This seemed a bit too much. Li Shimin's mouth twitched wildly. He never expected that Li Muyun would have exaggerated the update equipment to such an extent.

Li Jing was also speechless when he was criticized. He did not deny that weapons and equipment could make the people more at ease with this country, but now he is discussing whether there is any need to update the equipment, and the person who discussed weapons with you has used it.

Seeing a disdainful expression, Li Muyun shook his head in disappointment: "Actually, you don't have to believe it. The reason why I suggested that the emperor change the existing equipment was also good."

"What good intentions? Why don't you say come and listen to us?" Hou Junji said angrily.

"Okay, let's talk about it." Li Muyun said, patting the Baniu Crossbow beside him: "I believe that all you are familiar with is not as familiar as you. I want to ask now, if this thing is broken, how long will it take to repair it?"

"It depends on where the brokenness is. If the bowstring is broken, just change it." As a veteran on the battlefield, this problem obviously cannot defeat him.

But Li Muyun didn't seem to stop and continued to ask as he said: "Since that's the case, I want to ask, how long is this broken bowstring? How much pulling force can it bear? How long will it take to replace it?"

"This..." Hou Junji was instantly silent. He was a general, not a auxiliary army. In his opinion, he only needed to give orders. As for when the things could be repaired and what specific parameters of the equipment were, it had nothing to do with him.

Seeing that Hou Junji could not answer, Li Muyun did not ask any further questions, but instead changed to another question: "The question of bowstring is a trivial matter. You can always replace it with some effort, but what if it is broken in other places? For example, the bow arm, such as the support rack, can these things be repaired if they are broken?"

Li Jing shook his head and replied, "If the bow and arm are broken, it will be able to be repaired, but if the rack is broken, it will be broken and there is no way to start repairing."

Hou Junji bit his teeth for a long time and asked in a muffled voice: "Prince Xiaoyao, since you ask this, you won't say that the things you are going to study will not be broken, right?"

Yes, after asking a long time about how to repair equipment damage, I believe that the Prince of Xiaoyao should have an answer or a solution, otherwise he would not have asked this question.

The old guys who were asked were a little silly all around reacted, and they all turned their eyes to Li Muyun, waiting to see how he answered.
