At the beginning, his wife came to him, and he became rich by selling kidney treasures.

Looking at his progress, Ren Hao couldn't help but breathe a sigh of relief. Even though he still had two hundred taels of silver, the daily expenses for construction and food and drink were not small. If he didn't earn more, he would probably spend all his money.

In the evening, dozens of villagers came to Xu Hu's door and lined up in a long queue.

Xu Hu was carrying a bag of copper coins, Su Wan'er and the little maid Qian'er were sitting at the table keeping accounts, and Su Wan'er personally distributed everyone's wages.

Qian'er's beautiful handwriting made Su Wan'er and Su Ling'er very envious.

Soon, today's wages were paid.

Although Su Wan'er doesn't know many words now, she is very meticulous and her perseverance should not be underestimated. In just these few days, she has already recognized some words.

The next morning, Ren Hao got up early.

His eyes fell on the yard next to him. Looking at Ren Tiesan working hard, Ren Hao grinned.

It seems that I have to hurry up at the construction site, otherwise when Ren Tiesan reacts, he will not let me go.

Thinking of this, Ren Hao went back to the house, took out paper and pen, and wrote and drew on it.

He wants to make a weapon to protect himself.

In addition to being on guard against Ren Tiesan causing trouble for him, he also had to be on guard against Hu Sanyan playing tricks on him.

Since Su Linger has said it, then this matter is probably almost true. Now with the balance of power from Hu Sanyan and Guo Qian's lifelong sexual happiness, they dare not go too far.

Once I cure their illness, I'm afraid Hu Sanyan will show his fangs.

After writing and drawing on paper for a long time, Ren Hao finally drew a model of a crossbow.

The crossbow in the cold weapon era is as threatening as the sniper rifle in the hot weapon era.

The crossbows generally used in the army are more powerful. For example, a siege crossbow requires the joint efforts of two people and the help of gears to fire. The entire crossbow is also very large. The crossbow arrow alone is like a spear, and it is enough to penetrate a person and a horse when fired.

What Ren Hao wanted to make was just a small crossbow to protect himself.

He went to the construction site and found Yang Si to borrow the carpenter's tools from him. Ren Hao also asked Yang Si to get him some wood, and started doing carpentry work directly at Yang Si's house.

In just one morning, Ren Hao finished making the model of the crossbow and even made more than thirty arrows.

But when it came to finding the bowstring, Ren Hao was in trouble.

Ordinary hemp rope is simply not enough. Not to mention whether it can withstand the strong pulling force of the crossbow body. Even if it can be used, I'm afraid it can only be used a few times.

The bows and arrows used in the army are often made of cow tendons and cow hides, which are processed into tough bowstrings through glue.

But Ren Hao couldn't get this thing, so he had to give up.

Ancient China strictly restricted the slaughter and sale of cattle. As an important tool for farming, even if the cattle died of old age or disease, they had to be approved by the government before they could be sent to a special slaughterhouse for slaughter and sale.

There are not many oxen for farming in the entire Taoyuan County, and cows don't die every day. Even if he wanted to buy beef tendons, he might not be able to get them.

Frowning, Ren Hao slowly walked back to Xu Hu's house.

Su Wan'er and Su Ling'er were still studying with Qian'er, and Xu Hu's wife was still lying in the room to take care of her pregnancy.

However, Su's mother was busy, sitting at the door making clothes.

Ren Hao's eyes couldn't help but fall on the roll of silk thread in her hand.

"You can use silk thread to wrap the hemp rope to increase its toughness and reduce wear!" Ren Hao's eyes lit up.

Without hesitation, he found a hemp rope and wrapped the silk thread around it. To prevent corrosion, he also soaked the bowstring in lard.

In the evening, Ren Hao took out the bowstring and tied it to the crossbow.

He pulled the bowstring into the slot with force, inserted an arrow with a tail fin, and pulled the trigger hard at a willow tree at the door that was twenty centimeters thick!

Whoosh!

boom!

The willow trees rustled and many leaves fell.

Ren Hao walked forward, his eyes fell on the tree trunk, and he couldn't help but be stunned!

The arrow, which was only about 20 centimeters long, actually penetrated halfway into the tree!

The back end of the arrow had already cracked and shattered, but the tree trunk still emitted a burnt smell.

The powerful force of this crossbow surprised Ren Hao.

Ren Hao moved away a little and shot at the willow tree again.

Whoosh!

boom!

This time, the direction seemed to be a little off, and the arrow brushed past the tree trunk and shot into the ground next to it, leaving only a tail less than five centimeters long.

After trying many times in a row, Ren Hao couldn't help but smile bitterly when he saw that there were only a few arrows left.

The power of this crossbow was indeed beyond his expectations, but the arrows seemed to have become disposable items because the arrowheads were not made of iron but simply bamboo.

Although it can hit the target, it cannot be used again by waving.

"It seems that I will only have the chance to make iron arrowheads in the future." Ren Hao shook his head helplessly.

It is enough to protect oneself with bamboo arrows. If iron arrows are mass-produced, even the imperial court might want to kill oneself.

time flies.

In the blink of an eye, another two days passed.

Early in the morning of that day, Yang Si found Ren Hao.

"The living quarters have been built, and everyone has a bed, but the other places are not built yet." Yang Si said.

"Okay, thank you for your hard work!" Ren Hao patted Yang Si's shoulder.

Without hesitation, Ren Hao called everyone together and moved all the things to the new home.

Of course, Ren Hao didn't have much stuff originally, just some paper-making equipment, some clothes, firewood, rice, oil, salt, etc., and a pot.

Some of the meat and rice were left for Xu Hu, and Ren Hao took some away for himself.

After moving to the new house, Ren Hao became busy.

First, a piece of land was planned in front of the new house, and Yang Si was asked to dig it into a pool and put stones and clean sand at the bottom.

A flower bed was also planned next to the wall, where flowers will be planted in the future.

In addition to the kitchen and living room, Ren Hao also temporarily planned a bathroom and toilet.

Since there were no underground facilities, Ren Hao had to ask Yang Si to dig two dry toilets in a farther place, one for men and one for women.

It does smell a bit, but it's much better than defecating in the open air.

There are four bedrooms in total now. Ren Hao and Su Wan'er share the largest master bedroom, Su's mother has one for herself, and Su Ling'er and Qian'er each have one.

Ren Hao couldn't help but feel a little fortunate that he had prepared a few more bedrooms at that time, otherwise there would not be enough room!

However, thinking that there might be guests coming to stay, Ren Hao asked Yang Si to build three more simple bedrooms next door.

This will be enough for the time being.

Since the kitchen had not been completed yet, Ren Hao could only build a simple stove with stones in the yard and put the pot on it to cook.

After moving here, using water has become much more convenient.

The previous long-distance water diversion was directly led to a dry stream not far behind. Ren Hao found some bamboo, made a fork on it, and led the water directly to his home.

In order to prevent water overflow, Ren Hao made a switch with a very long hemp rope, moved the control interface away, and turned on the switch when needed. The bamboo waterway over there would be placed under the water flow and would be ready for use after a while. When not in use, it would be closed and the water would naturally be disconnected.

Just when Ren Hao was busy, a carriage arrived outside Caixu Village.
