Song Chen has never been a planned economist. Compared with this visible hand, he believes more invisible hand.

The market is a smart resource allocator. As the driving force of the market, people's selfish desires are often much more effective than those who are high-ranking for public and private forgetfulness.

However, Song Chen, who had traveled through time, did not practice his own philosophy. Terminator One, such an important project as converter steelmaking, was carried out through the visible hand of the imperial court.

There is no way to do this. These are all projects involving the survival of the nation. Even if the court wants to "free competition", Song Chen will not agree first.

"Song Chen, you have also seen that the firewood here is not enough, it may only be enough to cook rice. If you want to smel iron, the fuel may not be enough." Lu Wenhuan interrupted Song Chen's thoughts.

I was too anxious. It was a big problem for this main supporter to not support his "Honeycomb Coal Plan". Now he is already worried about how to effectively produce honeycomb coal, and he is really a little full.

Obviously, Lu Wenhuan realized the problem of insufficient fuel, but did not arouse enough awareness. When he was about to demolish the buildings in the city to cook, he would cry at that time, as if he was really crying.

Well, I, Song Chen, came here, seem to be preventing this kind of thing from happening.

"Shuai Lu, since I have mentioned the firewood issue, I have a bold suggestion this time." Song Chen deliberately stopped here, wanting to see Lu Wenhuan's attitude.

"Say!" Lu Wenhuan was not vague at all.

"That is to maintain half of the capacity to transport coal every day!" Before Song Chen finished speaking, he was rudely interrupted by Lu Wenhuan.

"Song Chen, are you crazy? Food is the most important thing, followed by weapons. Or I can accept it if you say you want to send some winter clothes to the soldiers, but it is ridiculous that you actually want to transport coal in." Lu Wenhuan said to scold Song Chen.

"You kid know how much is burning coal more expensive than burning firewood for a meal? I told you that it is five times more. Where did the imperial court get so much money to buy coal!" Lu Wenhuan almost shouted sternly.

Can't you print it? Jiaozi has been printed to a point where you are almost worthless. Song Chen secretly slandered himself in his heart, but he still didn't say it out.

Song Chen listened quietly, without saying a word or refuting it, until Lu Wenhuan was speechless and found that he was singing a one-man show.

"Tell me your reasons!" Lu Wenhuan is also a smart person. If Song Chen dares to come up with such an obvious "slutty idea", there will naturally be one or two reasonable reasons.

"One is the problem of firewood. It seems small but actually big. We are no longer savages who eat raw meat and drink blood. We must eat cooked food before we can swallow it to digest it. Without firewood, no matter how much food is, it is useless. Second coal is resistant to burning than wood. The fire energy (heat energy) of one kilogram of coal can be used as four kilograms of firewood, and it is one quarter of the volume of wood. The transportation efficiency is not as low as imagined. Third, because I have a way to reduce the cost of coal."

Song Chen's words were very convincing. According to his proposed "Honeycomb Coal Plan", if the honeycomb coal is made quickly, it will take three months later, so there is enough time to transport food and other materials.

There is another major premise here. It will take the honeycomb coal plan to be implemented in these three months without the cableway being destroyed by the Mongolian army. Unfortunately, they have noticed the strategic value of the cableway.

Today, a few Mongolian soldiers stood aside from afar and counted the capacity of the cableway.

Within the control of the Mongolian army, the shortest part of the cableway is twenty feet long, but Song Chen did not think he could rest assured. There are several ways to destroy the cableway.

Song Chen has this kind of thinking, which is what I can think of, and the enemy can think of it, it depends on when they will take action.

"It's three months later, it's not impossible to consider it," Lu Wenhuan pondered for a while, "I'm going to give it my best, okay!"

Song Chen was speechless for a while. I am helping you, so as to save you from crying in the future.

Lu Wenhuan, the "tour guide", was quite competent, and took Song Chen and the others to the streets. Xiangyang City under the besieged city had another prosperous future.

There are many vendors here. In fact, almost everyone here has become a businessman. Some sell their own mahogany furniture, some sell houses, some sell jewelry, and of course some sell rice and meat. There are often the most lively stalls there.

Song Chen was surprised to find that the people here did not have that look of despair. They were still quite happy and could not see the fear of the siege. According to his observation, there was no large-scale bartering situation. The prices were not outrageous, and the food had only tripled. It is generally believed that, just like before, General Lu could break the siege again within three months, and then there would be a steady stream of materials coming in Xiangyang City.

This is the illusion given to them by Lu Wenhuan, but he was right to do so. The widespread fear of the people is not a good thing.

But why didn’t this general who has been through many battles withdraw the people in the city at the first time? Ordinary people are not good for defending the city in the city.

After that, Lu Wenhuan left with tactfulness and asked them to stroll around by themselves. During this tour, Song Chen became even more worried. Xiangyang City was quite large and there were many people. For him, it was just a mouth for eating. Song Chen seemed to have seen a bottomless pit, and he had to drill in it.

General Lu told him that there were about 100,000 people in Xiangyang City, and Song Chen had the urge to turn against him on the spot, how should these supplies be done?

However, at least with beautiful women, when the Tianshan Tonglao didn't speak, she was so beautiful that she couldn't be said. Of course, Song Chen now calls her "Valkyrie".

I went around Xiangyang City and found that the surrounded city was open for restaurants, and the price was only five times that of usual. Song Chen felt that the price was quite generous because he knew that at the most difficult time, a white bun could be exchanged for a big girl.

After eating and drinking, Song Chen and his group returned to their residence. The sun had already set and the moon had not yet come out. At this time, Song Chen remembered to take a look at the cable car.

Although he had told someone to keep a special person to guard the cable car at night, Lu Wenhuan only partially agreed to Song Chen's request. Anyway, people were staring at the city wall every night to prevent the Mongols from attacking, and handing over the important task of guarding to these people.

When he arrived on the city wall, he saw these soldiers leaning against the bush to bet on the plug. Song Chen didn't say anything. These people were not under his control, but this was a bit too ridiculous.

He picked up the monocular lens placed on the table, and the sergeant who played with the plugs shouted loudly, "New, what are you going to do? Can you move this thing?"
