Sword and Sorcery and Martial Arts

Chapter 248 Explanation
Rhodes came out of the tavern. He rubbed his head lightly. He had a few drinks with these craftsmen just now. At the wine table, he explained everything clearly, and he didn't know if they listened carefully.

He asked the group of craftsmen to elect a person who is good at craftsmanship and able to manage them as the chief craftsman, who is responsible for supervising him to do these things.As for Hamer, let him rest for a few days before arranging other things for him. It is said that he hasn't slept well these few nights.

He plans to build a smaller mill not far from the big mill, so that law-abiding residents who pay taxes on time can use the small mill for free. As for the big mill, Rhodes plans to rent it out by the hour. Fees, for those merchants to use.

Flour that is as fine as that produced by a big mill is several times more expensive than ordinary wheat. Even if there is no merchant to rent it out, Rhodes can still buy low-priced wheat from farmers in the territory, and then sell the ground flour to other countries at a high price. place to go.

The construction of the mill building structure is not under the control of those craftsmen. They are mainly responsible for making various parts needed for the water mill.

After Rhodes asked them to manufacture these, they began to manufacture the instruments and equipment needed for textile and paper mills.

Now Rhodes suddenly felt that it was necessary to put the steelmaking plant on the agenda ahead of time. It would be a waste of time for these craftsmen to smelt iron ore into steel and then make parts.

Rhodes planned to build the steelmaking plant near the Rocky Mountain Range, so as to save the cost of transportation. There are coal mines and iron mines in the Rocky Mountain Range, and Rhodes discovered this.

Although he couldn't distinguish the types of rocks, he could still recognize red iron ore and black coal.

Rhodes returned to the big house. The Chief Grand Maester was sitting on a chair in the yard, and around him were several plows and carts that had been made in different styles.

"You're back so soon." The Chief Grand Maester noticed that Rhodes appeared in the yard.

"I roughly patrolled the territory. There are still a lot of work in the territory that I need to arrange, so I came back." Rhodes replied, "Have you tried the effects of these farm tools?"

"I tried it, and the effect is not bad. The temperature is so low in winter now. This thing called a plow can break through the frozen ground." The chief scholar said, "However, most people can't pull such a heavy thing. .”

"It can be pulled by a cow or a donkey." Rhodes replied, but he remembered that he had never seen such a big buffalo with a good temper that could pull a plow in this world.

The cows he saw were all long-haired cows of unknown breed, and they were not yaks on the grasslands. They were much bigger than yaks and had very violent tempers.

It may be a cow that has not been fully domesticated. Just like wild boars and domestic pigs, there are obvious differences in appearance and personality. However, this kind of cow tastes good and the meat is very tender. .

"Donkeys are okay, but they can't pull heavier plows." The chief maester nodded. "Although oxen can pull, they have a bad temper and may put farmers in danger."

Rhodes hadn't noticed this problem before, but there are always more ways than problems.

In fact, it is possible to study internal combustion engines and then create dynamic tractors to replace cattle to plow the land.

But this is also thinking about it, relying on the level of industrial manufacturing in this world, not to mention internal combustion engines and tractors, it is estimated that even one of the above parts cannot be manufactured.

Rhodes remembered that horses were used to pull plows in the Middle Ages in Western Europe, and several horses pulled together. However, such a luxury can only be imagined. It is definitely impossible for every village to use horses to cultivate land.

With this money, he might as well form a cavalry to plunder the wealth of nobles in other countries.

"Can you find a way to domesticate cattle? You don't need to domesticate a lot. Two or three cattle are enough for each village." Rhodes asked. He remembered that the chief scholar could speak animal language.

"You will ask someone to find a cow later, and I will have a good talk with it." The Chief Grand Maester nodded in agreement with Rhodes' idea.

"I have another very important matter to trouble you." Rhodes said again, he felt that he needed to find a few more things to keep the chief scholar busy, so as not to affect his construction plan.

"On the road of adventure, I heard a theory by chance. If this theory can be applied, our territory and even the entire Nord Kingdom will not worry about stomach problems." Rhodes thought for a while and said.

"What theory?" Rhodes' words aroused the curiosity of the Chief Grand Maester.

"This was discovered by a little nobleman of the Fish Kingdom. He was bored staying in the territory, so he started to plant the land himself. He planted a lot of peas. After several years, he found that the seeds of high-stem peas were grown. It's tall-stemmed peas, and the seeds of short-stemmed peas must be short-stemmed peas." Rhodes said after sorting out his thoughts.

"You mean to choose those crops that bear a lot of fruit, and use their seeds to sow, so that we can also plant crops that bear a lot of fruit." The chief grand maester nodded, "It really helps us."

"This is just part of it. The nobleman was really bored. Before the peas bloomed, he removed the anthers and filaments and put them in a bag. After the peas bloomed, he put the pollen of other pea flowers on the flowers and put them in the bag again." That is to say, he applied the pollen of short-stemmed peas to the flowers of tall-stemmed peas," Rhodes said again.

"Then what?" asked the Chief Grand Maester, "So you get peas of the middle height?"

"No, I still got high-stemmed peas, but after planting the fruits of these peas, I got high-stemmed peas and short-stemmed peas. The nobleman studied mathematics, and he found the ratio of high-stemmed peas and short-stemmed peas through statistics. It's almost 3:1." Rhodes said again.

"Hey, what does this mean? The characteristics of the grandparents will be reflected in the grandchildren?" the chief academician said to himself.

"He planted again the seeds of the first generation, the seeds obtained by rubbing the pollen of the dwarf pea on the flowers of the tall pea. Then he spread the peas of the dwarf pea to the first generation On the flowers that bloom from a generation of seeds." Rhodes continued.

"You got high-stem peas too?" asked the Chief Grand Maester.

Rhodes shook his head, "The ratio of high-stemmed peas to short-stemmed peas is about 1:1."

"How did this happen? Why did this result happen?" the Chief Grand Maester asked suspiciously.

In this way, the experimental process and results are taken out, and it is difficult for people who have not studied biology to think of the principles contained in it.

This is a very classic experiment done by Mendel, the father of genetics, which can be called the origin of genetics.

"Peas are strictly self-pollinated, cleistogamous plants, which means that in nature, all peas are homozygous, and he bred heterozygous peas by that method, and heterozygous peas selfed , the ratio of dominant traits to recessive traits in the offspring is 3:1." Rod explained.

"What is homozygous? What is heterozygous? I can understand the traits, that is, the characteristics of tall stems and short stems of peas, right." The Chief Grand Maester interrupted Rhodes.

"Don't talk yet, I'll explain to you slowly." Rhodes said again...
