However, Yu Weichao is not a professional intelligence officer, and he gets more public information. Nevertheless, it also helps Chen Yi to make a basic judgment.

At present, they know that Mala City is the largest city in the neighborhood, and the other two cities are similar, both of which implement the city-state system, just like Greece in classical times.
Yu Weichao told me that there are two monsters in Central Mala City.
On the one hand, it is difficult for farmers, herders or hunters to get a lot of food to Mala city, but the number of residents in the city is not less than 53 thousand, which is a very large population base, but I don’t know if they can maintain their basic livelihood
Second, cities such as Mala City advocate war. Young children go into long houses to live and train, and when they grow up, they go to distant places to participate in the war, which is often aimed at another alliance city-state. This is also the most important thing that urban residents need to bear. However, from the perspective of modern people, their war has almost no impact on Mala City. At first glance, it seems to be pure dedication, which scientists can’t understand in the era of energy conservation.
Chen Yi doesn’t think too much, and a city with ancient style gradually comes into his eyes.
Yu Weichao burst the letter card girlfriend’s tone and heart. "The stone wall on three sides of Shuizhai is 5 meters high and 2 meters wide. The wall is completed by animal power and manpower. It takes only three months to build a watchtower. After everything is completed, a bunker will be built around it …"
……
Chapter two hundred and forty The Knights of the Western Continent
The 11-meter-long stone wall sounds simple, but in fact, it is equivalent to dropping 11 cubic meters of stone, thus sweeping away the stone near Mala City. Shi Cun even moved six people to live by the Shuizhai to facilitate daily work.
In addition to the heavy wooden door with iron outside the stone wall, it also costs a lot of money. Considering that it is not convenient to import steel directly from the earth and that Yu Weichao has not appeared for a long time, he will exchange clothes and scissors for coarse iron with impurities and then temper it himself to make the door-covering material. This process is also simple as it sounds, but difficult to do. Forging coarse iron requires building a blacksmith’s furnace. When the temperature reaches enough, it is necessary to make coke and blowers …
Fortunately, Yu Weichao studied hard when he was in school, so if he has any questions, he can rarely seek specific answers from the brain he brought with him. Otherwise, trying to re-create the field exercise will kill people, and it is not so simple to copy it. After so many years of China’s cottage business, it is still a cottage level, but it is not satisfactory.
Yu Weichao will not elaborate on these difficulties, which will show that he is too idle. Compared with his position, he deliberately said, "The amount of cash or goods in the city has never exceeded 10,000 shellfish, which is probably one tael of silver in ancient China."
Communicating with modern people is convenient for Chen Yi to nod his head to show his understanding, but he dug out the snail shell from his pocket and said, "Do you think the shell is this kind of shell?"
Yu Weichao was surprised when he saw a rich man. "Of course not. It’s a snail shell. It’s worth 10 thousand shells." Chen Yi was slightly dissatisfied. "Do you know what material it is?"
"gold?" Yuweichao will be good at it. "You don’t want to take it back, do you? There are a lot of things in 10 thousand shells, which cost thousands of dollars less. Even if this shell weighs half a catty, it is worth tens of thousands of things. "
He still looks down on the business with multiple profits.
Chen Yi thought that it was no use for a literary theorist to have studied mathematics as a pure scientist. He shook his head and replied, "It is not gold."
"No?"
"Of course not," Chen Yi affirmed. "The specific gravity is different from that of gold. It must be some rare metal. I will test it when I get back."
Although there was no direct criticism, not only Yu Weichao felt something, but also hurriedly said, "I will pay attention to this information when I go back."
He said wryly, "I still think it is important for organizations not to make money. It is still very important to build a colonial bridgehead with real materials."
Yu Weichao quite understood Chen Yi’s idea, and two or three sentences made him lose his temper.
Chen Yinai said, "Now I don’t make small money."
He talked about the snail shell, and by the way, he negotiated a sword deal yesterday, saying, "I have all the materials with me, so you should think more about safety."
"Our ship transaction" Yu Weichao is very thoughtful. "The local shipping is underdeveloped and it is said that there are monsters in the water. The 10-ton and 20-ton ferry is a big ship. After the ship transaction, each side will go its own way, even if there is a fish in troubled waters, it will not dare to start a boat."
"Dare not?"
"A ton boat is fragile, and those mercenaries with great strength can chop the planks with axes. We have enough rockets to sink the goods, so it’s hard to fish in such a big water. It is said that …" Yu Weichao stopped at this moment and continued, "When can we get some weapons?"
He said that nature is a hot weapon
Chen Yi hesitated and didn’t reply immediately. He didn’t give Yu Weichao hot weapons, but to some extent, he was also guarding against him. But now it seems that this kind of defense is really not necessary. But there is another question here. Who will master the hot weapons?
He immediately asked, "What does she Lei do?"
Yu Weichao seems to have an answer early, saying, "Be stationed in Shuizhai every day and do your duty."
That’s an interesting answer. Being stationed in the water village says that what he does every day is conscientious, but it’s not necessary that the water village is big. Since there is no invasion by outsiders, there is no credit for being stationed …
"Call him over." Chen Yi lifted up his eyes and looked into the depths of the river and the mountains and water villages not far away. They are still uneasy and may be attacked by various characters at any time, but its defense depends on mercenaries …
Mercenaries are not as good as village soldiers for city guards.
Can’t martial arts school students find allies from the ground yet? However, the number of our own people is too small, and it is not good to guarantee the loyalty of the township soldiers. The western mainland does not cultivate land, and the mainland wants to get some attached land. It is really worrying that farmers do not have it.
Yu Weichao is not a real administrative official, and there will definitely be some mistakes in managing such a big stall. If the official has a mistake, there will be a mistake in the western continent. I am afraid that he will have to live with his life. In this case, he will have to find two deputies for him after all …
In thinking, She Lei slowly came to Chen Yi.
At that time, he did not care about him because of the magic of the western continent, but it is impossible to say that he did not complain about the contrast between the earth and the decline and danger of the western continent after so many months.
Chen Yi was too young to judge how much resentment she Lei really had on the surface, so she floated and asked, "What do you think of the western mainland for so long?"
If a wise man should sell his loyalty now to impress the Lord, he was a punk who made the biggest decision, that is, to participate in the martial arts school and train well. Why can’t he be degraded to the barren land because I made a small mistake when I trained hard?
