"It won't break? How is that possible! Old man, you're thinking too much." As everyone watched, Li Muyun shook his head and said, "There is nothing in this world that won't break. At most, you can just use it for a longer time."

"Since that's the case, are you just humiliating me and others!"

Hou Junji rolled his eyes in anger. After talking for a long time, I thought you could make a Baniu Crossbow that would not break, but you actually said that it would be broken, so why are you pretending to be?

Li Muyun knew that he could never recite the charge, so he took the conversation and said, "We can't say that. We are discussing it. It has nothing to do with humiliation or not. The reason why I asked this is because I have a way to solve these problems."

"Solved? How to solve it?" Li Shimin became somewhat interested and sat upright.

"Simple!" Li Muyun snapped his fingers: "Unified standards, modularize and standardize all equipment. As long as this can be achieved, the problem of equipment updates can be easily solved."

"What's the meaning?"

Modular and standardized, several old guys sitting together can understand every word, but it makes people confused about what it means to put together.

Seeing that it had successfully aroused the interest of the old guys, Li Muyun smiled slightly: "Let's do this, I just made a shelf and put it outside. If you are interested, I can have someone carry it in, so that it will be better explained."

"Well, carry it in." Li Shimin really wanted to see what the magical thing that was blown by Li Muyun looked like.

A moment later, a pure iron rack was carried into the yard and placed next to the Eight Niu Crossbow.

Several old guys surrounded each other, looked at Li Muyun for a long time, and then looked at him in a daze: "Aren't you just changing the wood for iron? Is this what you meant to be modular?"

"Of course." Li Muyun nodded and waved to the strong men who had just brought in: "You guys, take this thing apart and let the adults see it."

"No!" Several strong men agreed, quickly stepped forward, took out the tools in their hands and tinkered on the square rack for a while. Soon the rack was dismantled into dozens of iron pieces, large or small.

"This..., what is this for?" Li Shimin walked around the pile of broken iron blocks, vaguely thinking about something in his mind, but he was a little uncertain.

Li Muyun smiled and said, "These are all made according to certain standards, and each piece has its own number."

As he said that, he helped up a longer iron block: "For example, the label on this one is 'Feet 1', that is, this is a leg, numbered 1, height three feet, but is located in the front left. If the rack damages this leg during battle, then you can remove such a piece from any other equipment and install it directly. And you don't have to worry about whether it is suitable for use."

"Also, this is just a rack for the Baniu Crossbow. We can also produce some racks for catapults. The height of the legs can be made with the same standards as this. That is to say, if there is a battle in the future, as long as we put some spare parts on it, we can transform the Baniu Crossbow into a catapult at any time. Similarly, the catapult can also be changed to a Baniu Crossbow."

"This is the benefit of modularity and standardization. The entire equipment and all accessories can be disassembled at any time and replaced at will, which can ensure the reliability of the equipment on the battlefield."

"Of course, another advantage of doing this is that craftsmen do not have to perform too complicated operations, and do not have to build different equipment like before. As long as they are trained, the blacksmith who will serve as supervisors can create all the equipment."

"Hiss..., if this is the case... it seems that there is really a need to upgrade equipment." Li Jing nodded slightly and looked at Li Shimin and said, "Your Majesty, what do you think?"

"I think it is very necessary. Even if the equipment reliability is not considered, such things that can be disassembled and assembled at any time can provide great convenience in transportation."

Li Shimin was an emperor after all, and he looked at the problem differently from Emperor Wen. When he joined the army to fight the first battle, he knew that the most troublesome thing about the Eight-Nuo Crossbow and the catapults were actually not the use, but transportation.

These equipment are of great use in siege and defense battles, but transportation is also a big problem. An eight-ox crossbow can often cost hundreds of kilograms, and transporting it to the battlefield is a big problem. It would be fine if it is a short-distance marching. If it is a long-distance marching, this thing can only take away the bow on it and the rack below is thrown away.

But if we follow the modular design like this, it would not be so troublesome to bring the equipment to the battlefield in the future. Just disassemble it, each person will carry a few pieces on his back, and then assemble it together when he arrives on the battlefield. It will be very cost-effective to consider the time alone, and even if you can, you can equip the troops in large quantities.

Thinking of the large number of equipment troops, Li Shimin's eyes were already burning with war, and it seemed that he saw hundreds or thousands of Eight-Cow Crossbows launching a stormy attack on the enemy's army.

In the past, when facing the enemy's attack, I used a bow and arrow to cover it, and I probably wouldn't need it in the future. I would get more Eight Niu Crossbows. Whoever dares to fight against the Tang Dynasty will directly cover it with the Eight Niu Crossbows. If a crossbow gun is more than one meter long, even if there are 100,000 people attacking, he will kill half of it at once.

At this time, Hou Junji didn't bother to argue with Li Muyun, and greeted the strong men who had just removed the shelf: "Come here and put this shelf on."

"No!" The strong man dared not disobey, so he quickly stepped forward. After about a quarter of an hour, he assembled the rack again.

Looking at the assembled rack again, Li Shimin, Li Jing and others soon saw some tricks, pointed to several connecting positions and asked: "What is this? Why can the iron tools be connected so quickly?"

"This is called a bolt. It is my new research and can come in handy in many aspects." Li Muyun explained.

"Bolt?" Li Shimin walked closer and looked at the bolts that were very common in later generations curiously. He even pushed the assembled iron rack himself. He found that it was not moving at all, so he nodded with satisfaction.

"What is this? Why are there so many holes on these two legs? And why are these two legs broken?" Li Jing soon discovered the problem and asked at the two hind legs of the iron rack.
