Everyone fell silent after being told off, mainly because the Duke was right; they indeed lacked the ability to solve the problems for the Great Dynasty.

After the emperor reprimanded him, he wrote a letter and had it delivered to Longyuan, who was far away on the border.

After returning to her room, Su Muyao locked the door from the inside and entered the space.

Soon they started finding some wood in the space and sawing it into the shapes they wanted, drying what needed to be dried and soaking what needed to be soaked in oil.

Most importantly, they started preparing the food with great effort, and then processed each item one by one.

The little one was busy and sweating profusely. After finishing, he started writing and drawing at the table.

Su Muyao knew that if she wanted to live a peaceful and comfortable life in the Great Dynasty, she should make the Great Dynasty rich first.

You must at least become someone that all countries fear, and at the very least, you must be able to fight back and protect yourself if someone attacks you.

I am a modern person standing on the shoulders of giants, and I have such great opportunities.

That emperor was quite benevolent; at least when others threatened him and forced him to make a choice, he firmly chose himself. For that alone, she had to help that old emperor secure his throne.

In fact, when the emperor was about to make a decision, she had already figured it out: if the emperor chose the crown prince, then she would take her family and live in seclusion.

It wouldn't be so bad to find a beautiful, secluded mountain valley, build a few houses, and live a peaceful and tranquil life away from the world.

However, this old man was a wise ruler who cared deeply for the country, which made me change my mind instantly.

I am still young and there is not much I can do. I have the emperor protecting me now, but what if even the emperor can't protect me?

Therefore, she had to plan ahead.

Today, the iron smelting technology of this dynasty is underdeveloped, and its weapons are not as advanced as those of the Warring States period that I knew in my previous life.

You can tell from the long swords these guards use that they are quite heavy and cumbersome.

However, iron is extremely brittle and not hard enough, making it difficult to use. People with less strength can't even lift a large knife.

Not to mention that modern steel knives can't compare, even the craftsmanship of iron is far inferior.

In the Great Dynasty, it was illegal to carry a sword without prior registration, but as the Imperial Advisor, Su Muyao naturally didn't have this problem.

It seems we need to develop weapons suitable for these soldiers, ideally weapons that can be used for both close and long-range attacks, and are also easy to carry.

The first thing that came to Su Muyao's mind was the bow. Although the bow is suitable for long-range attacks and group attacks, it requires strength to draw, and it is also bulky and inconvenient to carry, and it is not suitable for close combat.

Su Muyao thought of the crossbow she had prepared before; if it could be made, it would change the entire dynasty's fighting strength.

Although I still have quite a few in my own space, I still need to make them. I figured making a crossbow wouldn't be too difficult.

A crossbow is a bow that uses mechanical force to shoot through objects; crossbows are generally made of multiple layers of bamboo.

The composite bow made of wood chips and glue is shaped like a carrying pole, hence the common name "crossbow pole".

Although it is relatively simple to make, it was known as "one crossbow takes ten years" in my previous world.

Such highly lethal weapons are subject to strict state control.

The crossbow consists of several parts, with a horizontal bow-holding hole at the front to secure the bow and prevent it from moving left or right.

The wooden arm has a groove-shaped arrowhead on the front for placing the arrowhead, allowing the launched arrow to travel in a straight line.

Nowadays, stability and forward propulsion are very simple. There is a box at the back of the wooden wall, which becomes the crossbow mechanism. Inside the box, there is a hook for hanging the string, called the tooth.

A sight was mounted behind the tooth.

The trigger is attached to the bottom of the crossbow. When firing, the bowstring is automatically pulled back and hooked onto the hook. After placing the crossbow bolt on the arrow path and aiming at the target, the trigger is pulled.

The teeth will retract, and the bowstring hooked by the teeth will spring out, allowing the arrow to be shot.

This is probably the only weapon that Su Muyao can quickly create with high lethality right now.

The oldest crossbows were always single-shot, but Su Muyao made them into rapid-fire crossbows.

It can fire up to twelve arrows at a time.

Looking at this pile of drawings, I had no choice but to make improvements step by step based on what I could understand.

Finally, I improved the design and put it on paper. I made a few of them myself first, so that at least I could have some credibility.

Then we'll have the people from the Ministry of Works mass-produce it.

Suddenly, I thought of the crossbows used for assassination that I saw in TV dramas in my past life.

It's about the same as what I have now, the only difference is that I'm much, much younger.

And it only needs to be hidden in the sleeve, especially when it's covered by loose clothing, so most people won't notice it.

Su Muyao stayed in the space for several days, but to the outside world, it was only a little over half an hour.

She took out two large baskets of strawberries from the space.

He placed the strawberries in the room and fiddled with the smallest crossbow in his hand.

Xi Bao and Huan Bao were quietly reading in the courtyard. Now that they were scholars, they had become very calm and composed.

He was already a scholar at the age of thirteen or fourteen; his future is promising.

Only Su Mingxuan is still laughing and joking every day, so mischievous! *罒▽罒*

As soon as Su Muyao came out, she was surrounded by Su Mingxuan.

"Little sister, you brought strawberries."

The little guy didn't even ask where his little sister got the strawberries; instead, he stared at the basket of strawberries with drooling eyes.

These strawberries look bigger and juicier than the ones my younger sister brought out before.

Su Muyao placed the basket of strawberries directly on the stone table in the yard.

"Eat quickly."

Then he called Xibao and Huanbao aside, saying, "Give it a try."

The two little ones went to see their little sister. What did she take out?

Upon closer inspection, it turned out to be a crossbow? Putting aside its extremely small size, the material and style were somewhat unlike the crossbows commonly used today.

Before the two little ones could even ask, Su Muyao said, "This is a new type of weapon I developed, and it's incredibly powerful."

If you encounter danger again, you can use this by hiding it in your sleeve.

Next, Su Muyao taught her two older brothers how to use it, while Su Mingxuan sat on the stone bench eating happily.

Soon the commotion in the courtyard attracted the attention of the three Su brothers. The eldest brother looked at the weapon his niece had used and knew it was no ordinary weapon.

The three brothers stared longingly at Su Muyao, wondering if they would get a share.

As expected, Su Muyao did not disappoint them. In the next second, she took out three that were much larger than the ones the two children were currently holding.

He sensed something different as soon as Su Laosan started working with him.

When he stood in the yard and raised his arm, he realized that this thing could actually be aimed.

"With this, the accuracy problem will be solved."

Su Laoda examined the crossbow in his hand and said, "With enough training, you can hit the bullseye every time."

Boss Su's tone was full of confidence.

Su Lao Er and Su Lao San nodded frequently.

"Father, try shooting an arrow."

Su Laosan aimed at a large tree not far away and pulled the trigger to fire.
