I was kicked out of the house, and I was reborn and became the emperor

Soon, a young boy, slightly shy, walked out of the house, knelt down and saluted, stuttering: "I greet... the Marquis."

"I haven't been crowned king yet, so there's no need to call me that. I'm just a marquis." Fang Yi smiled and helped the young man up.

The young man bowed again: "I greet you, my Lord."

Fang Yi carefully looked at this seemingly ordinary boy and asked, "How old are you this year? Is this welcoming wooden dog your work?"

"I am fourteen years old this year, and that wooden dog mechanism is my work." The boy looked at his grandfather, a little reserved.

"What are you afraid of? The Marquis is not Lu Dongxun. He won't eat you!" Lu Quanxin said coldly.

Fang Yi didn't take it seriously and continued to ask gently, "Little craftsman, can you tell me the principle of the mechanism of this wooden dog? How can it be so exquisite?"

The young man nodded and explained the principle in detail. It was just as Fang Yi expected. It had a structure similar to a spring and a clockwork inside. By turning the tail, the mechanism could be wound up, making the wooden dog come alive.

Although the principle is simple, it is rare that it was created by a teenager who is not even fourteen years old.

Fang Yi admired the young man more and more. Recalling that the men in the village were good at bows and crossbows, he asked, "Young craftsman, have you also mastered this skill? Can you show me a few?"

The boy looked at his grandfather, and after getting his grandfather's permission, he quickly returned to the house and took out a crossbow with a peculiar shape. This crossbow had a novel design, with a short string and a long frame, a high arrow box, and a device similar to a sight installed on the top.

Under the gaze of everyone, the young man carried the strange crossbow on his shoulder, his temperament changed, he was no longer timid, and his eyes flashed with wisdom and bravery.

With a light pull of the trigger, tiny arrows shot into the tree trunk accurately like meteors. Fang Yi counted silently in his mind and fired ten arrows in a row, all of them hit the target!

Looking at the arrows densely covering the tree trunks, Fang Yi's heart was filled with incredible shock!

Even the famous Zhuge Crossbow could only fire ten arrows at a time, but the craftsmanship of this young carpenter has enabled the crossbow to fire fifteen arrows at a time. Its exquisite design, lightness and portability are amazing.

"What a young genius! I am so lucky to have picked up a treasure again..." Fang Yi murmured to himself, unable to hide his excitement.

Unexpectedly, the old carpenter Lu Quanxin sneered and said, "What young prodigy? He is just a toy of the little grandson. How could he move the Marquis so much?"

"What do you mean?" Fang Yi asked in confusion.

"Your Majesty, you might as well take a closer look at the arrowhead on the tree trunk." Lu Quanxin gestured.

Fang Yi looked carefully and suddenly understood.

It turned out that although this crossbow could hit the target accurately, its penetrating power was obviously insufficient, and the arrows only embedded shallowly in the bark.

There were also a few tiny arrows that gently fell into the dust as the breeze blew. Obviously, there were still many shortcomings in using them in actual combat.

Seeing this, the little carpenter blushed and scratched his head embarrassedly.

Despite this, Fang Yi still has high hopes for the talented young people. After all, with such a foundation, improvement and innovation are just around the corner.

"This is already commendable. Compared to the maids around me, you are still obsessed with romance novels at your age."

"My lord! Why do you bring this up?" The maid Xiaorou pouted and pretended to be angry.

"Thank you for your praise, sir. If you are interested in bows and crossbows, my grandson has another work that will probably surprise you even more." Lu Quanxin smiled proudly, his face full of pride.

"Oh? Then take it out quickly and let me broaden my eyes." Fang Yi's curiosity grew stronger and stronger. Just from the subtle change in Lu Quanxin's expression, he had guessed that this other crossbow was definitely not an ordinary item.

The young carpenter quickly took out another crossbow. At first glance, its appearance was not much different from the previous crossbow.

He still held it steadily on his strong arm, aimed at the tree trunk, and pulled the trigger.

However, what followed was not only the shooting of crossbow arrows, but also a deafening noise and a series of dazzling flames, which scared Xiaorou into screaming.

Fang Yi was so shocked that he was surprised to find that the crossbow arrow almost pierced through the tree trunk!

However, this repeating crossbow also has obvious flaws. Compared with the previous crossbow that could fire fifteen arrows continuously, it could only fire five arrows.

Moreover, the accuracy was poor, and only two arrows hit the target at such a close distance.

What’s even more terrible is that after five arrows were fired at the same time, the entire crossbow broke into pieces and was completely scrapped.

Fang Yi sniffed the special smell in the air and said, "Is this gunpowder? Gunpowder is added to the crossbow to help the arrow?"

"Yes... yes." The young carpenter nodded in acknowledgement, and then gave a brief explanation of the principle and structure.

After hearing this, Fang Yi smiled and said, "Since you are using gunpowder, why not replace the wooden crossbow with a metal one? This way, it will be both sturdy and stable. Moreover, given its powerful thrust and penetrating power, you can design it to be more compact, so wouldn't you be able to avoid the risk of explosion?"

"Explosion? What does this mean?" The young carpenter looked confused.

"I mean, making a crossbow out of metal would be stronger and more stable."

“But I’m just a carpenter and I don’t know how to forge iron.” The little carpenter scratched his head and answered with a silly smile.

"Little carpenter, the fact that you can invent such a wonderful thing shows that you have endless creativity. Never limit yourself and be brave enough to break through." Fang Yi spoke earnestly, and the little carpenter nodded as if he understood.

Fang Yi patted the young carpenter on the shoulder and continued, "You should not stop at learning forging, but should learn more and integrate what you have learned. Only then can you create more wonderful things and even turn stone into gold!"

“Turning stone into gold…” There was a gleam in the little carpenter’s eyes, as if these words had inspired him to have infinite potential.

Looking at the young carpenter's passionate expression, Fang Yi nodded with satisfaction and asked, "Do you understand?"

"I understand! Thank you for your guidance, Lord Marquis!" The little carpenter knelt down with a plop, full of awe for Fang Yi.

"Get up, there's no need for such a big gift. By the way, your last repeating crossbow is very well made. Can I take it back and study it carefully?" Fang Yi asked.

"Of course, it's just damaged." The young carpenter hurriedly handed the broken crossbow to Fang Yi.

"It's okay, the internal structure is still intact." Fang Yi happily asked Xiaorou to properly store the crossbow, while he himself fell into deep thought...

Although firearms already exist in this world, most of them are still at the level of muskets. Even a three-barreled musket can only fire three shots in a row, and becomes useless after firing.

The little carpenter's repeating crossbow is actually closer to the concept of a repeating rifle. Once perfected, it can achieve the effect of seven consecutive shots.

If continuous loading can be achieved, it would be the prototype of a pistol!

Although what he learned in his previous life was not weapon making, it might be able to give the little carpenter some inspiration.

If we can really create a firearm with great power and high precision, it will undoubtedly change the battlefield situation!
