Early the next morning, Xiao Ding still asked Zhao Hu and the others to pick a few baskets of green vegetables, and went to the hill again to catch two pheasants and two hares, and put them in baskets and covered them.

Then let Zhao Laixi set up the carriage he bought yesterday, and moved the basket into the carriage, still wrapped in a quilt. Then, he instructed Fan Sanpang and the Ou brothers and sisters a few words, telling them to be cautious and pay attention to preventing the man in black from returning. After that, he and Zhao Laixi drove towards Luoxia County again.

sent vegetables and other things to Xiangmanlou, and received thirty taels of silver. Zhao Lai was so happy that he couldn't close his mouth.

He didn't expect that this stupid uncle would actually think of such a good way to make money, and the vegetables planted in the two wooden boxes of the greenhouse at home were almost six acres together. Vegetables are also planted in batches according to Xiaoding's instructions, and the growth period of green vegetables is very short, generally half a month to 20 days can be picked, so that this winter, you can pick vegetables almost every day to sell. How much money you have to make this winter!

After selling the vegetables, Xiao Ding and Zhao Laixi drove to the north of the city, and the two found a shop called "Mo's Blacksmith Shop". Chatting with the shop owner, I learned that this "Mo's blacksmith shop" was opened by the three brothers of the Mo family, three people and one milk sibling, they are brothers, and the family heirloom blacksmithing skills, when the shop was in the hands of their fathers, it was already famous in Luoxia County.

Xiao Ding took out the drawing of the Lianzhu crossbow and handed it to Mo Dalang, and explained the intention.

"Although the parts of the crossbow arrows are very delicate, they can't stop our brothers." Mo Dalang said after reading the drawings.

When Xiao Ding heard this, he put his heart down, and his greatest fear was that the blacksmiths of this era would not be able to create the parts on his drawings.

"Since that's the case, then it's hard for the three of you!" Xiao Ding said with a smile.

"Yes, yes, meeting the needs of customers is what we should do." Mo Dalang said humbly.

"For the crossbow arrow parts of this size on the drawing, you can help me make ten sets, and then you will reduce it by two-thirds according to this size, and also help me make ten sets of small models, as for the arrows, these two sizes will each help me make a hundred arrows. Be careful, be sure to use some good steel materials to make it, you can rest assured, I will be grateful when it is done. Xiao Ding instructed.

Mo Dalang and the two brothers beside him, Mo Erlang and Mo Sanlang, promised again and again: "Guest officer, please rest assured, we will definitely do what you tell us to do and ensure that we can help you build a good crossbow arrow with quality and quantity." ”

"In addition, there is one more thing that needs to be said, you must not pass on my crossbow arrow production method to me, understand?" Xiao Ding reminded again. He feared that someone else would learn to make such crossbow arrows and use them against him later.

"Okay, no problem, we will never pass it out without your permission, you can rest assured, guest officer." The three Mo Dalang brothers answered again and again.

"I wonder how many days it will take your three brothers to build these crossbow arrows?" Xiao Ding asked.

"This, I'm afraid it will take at least half a month, these parts are a bit delicate and time-consuming." Mo Dalang said.

"Half a month, it's a bit long...... "Xiao Ding felt that he didn't want to wait for a day, who knew when the man in black would suddenly return!" Can you go any faster? I'm in a hurry, can you work overtime......"

"It will take ten ......days at the earliest" Although Mo Dalang didn't understand what overtime meant, he also understood that Xiao Ding was in a hurry to get this batch of crossbow arrows.

"I can pay you double the price, you might as well hire a few apprentices to help you build ......," Ding suggested.

"Even if we hired someone to help, it would have taken at least seven days to build this shipment." When Mo Dalang heard Xiao Ding say that he could pay double the price, he was naturally very happy, of course it wouldn't cost much to hire someone. In particular, those who hire apprentices, some of whom come to his house to learn the art of iron, not only do not need to pay wages, but also need to pay tuition.

"Okay then, it's just seven days, I'll come and pick up the goods in seven days." Xiao Ding also knew that forging iron in this era was all by hand, and without the lathes of later generations, it would take a lot of effort.

Leaving the "Mohs Blacksmith Shop", the two of them still found a place to eat casually, bought some grain, rice, meat and other things on the street, and then drove back to Luoxia Village.

Everything is safe at home, and the man in black did not come again today.

Because of the potential safety hazards in his home, Xiao Ding decided to let the construction workers at the construction site give priority to building the courtyard wall, and he planned to enclose the more than 30 acres of land and the small hill behind it with a fence, so that outsiders would not easily enter his house.

The construction on the hillside was nearing completion, but there was a problem with the reservoir on the mountainside. Although the workers made great efforts to dig a pond on the mountainside, when the spring water was brought in, it was discovered that the pool could not hold water. When the spring water flows into the pit, it seeps into the ground.

The mountainside is not like the foot of the mountain, where there are rocks in the ground, and after digging a cistern, the water will not seep into the ground. On the mountainside, the ground is almost entirely fertile and soft, and it is impossible to hold water.

Second Uncle Niu once thought about laying a layer of stones at the bottom of the pit, but there were still gaps between the stones, and it was still impossible to effectively store water.

Xiao Ding listened to Second Uncle Niu's report and frowned. He knew that if this problem was in the afterlife, it would not be a problem at all. Because there was cement in later generations, it was only necessary to use cement to smooth the stone joints.

It seems that it is time to look at how to make cement.

Xiao Ding had seen the formula of the original cement on the Internet before crossing, which was mainly composed of four raw materials: lime, clay, iron slag, and gypsum. It's just that Xiao Ding doesn't know the ratio of these four raw materials. The first three of these four raw materials, Xiao Ding felt that they should be easy to obtain, only gypsum, but he didn't know where to find it.

However, Xiao Ding guessed that the reason why the cement was mixed with gypsum should be to speed up the solidification of cement, so he planned to use only the first three raw materials to try. Without gypsum, it's just a slower setting time.

The lime in the first three materials can be found in the nearby mountains, and the limestone can be found and transported back to calcined, and then ground into powder, as for the clay, it is very easy, and the clay used by his family to build a house is dug near the root of the mountain behind the back village. As for iron slag, you can go to some blacksmith shops to collect it.

Xiao Ding followed Second Uncle Niu to the mountainside of the hill, and saw that this reservoir was really not small, and the radius was five or six zhang. With such a large pool, you can raise fish in it.

The bottom of the pond and the edge of the pond were paved with stones, but the spring water still seeped into the soil through the cracks in the stones. It seems that the development of cement is imminent.

Xiao Ding immediately asked Second Uncle Niu to arrange manpower, some of them to dig clay, and some of them to follow him to the mountains near the village to find limestone.

Sure enough, the hard work paid off. On the small mountain range south of the village, Xiao Ding and the workers found limestone. Xiao Ding asked the workers to mine the limestone and transport it to his home in a wheelbarrow.

Immediately after that, the clay diggers came with the unexpected news that they had found a black stone......
