"I think the people of Chu need coke and coal, because these things are iron smelting. Steelmaking is necessary, we have not found a large amount of coal in the territory of Chu at present, we can transport coal resources to the territory of Chu through some ports to help them smelt steel. We have the technology. Li Zuoche emphasized.

"But our steel technology is not yet mature, in terms of steel output, the people of Qin far surpass us, and we cannot surpass Qin in some special steel technologies." Li Mu said.

"However, the people of Chu want to have their own steel technology, their idea is very simple, and we have mastered such technology, this is our advantage, if we don't cooperate with the people of Chu, the people of Qin will too. So, let's do something ahead of time. In this way, it will be beneficial for our Zhao State to act. Li Zuoche said.

"Well, yes, we still have a lot of coal resources anyway, that's all." Li Mu decided. As for how to implement it, it depends on the deployment of the following economic sectors. At present, some enterprises are still state-based, such as military factories and large-scale factories such as Handan Iron Works. The state holds a large part of the shares. Some specific things are still done by them, but the coal mines are occupied by private aristocrats. The state treasury did not take any more shares.

Chu State, Danyang County.

"Professor, you said, will the iron ore we found be used on it?" Student Zhao Shan said worriedly. He was a student at the Zhao State Mining School, and he studied hard, and this time they discovered such an iron ore mine, but also found other associated mines, such as phosphate rock, which can be used as fertilizer, and has many other uses.

"These things are not something we guess, we just need to find the mine. As for how to use it, those are businessmen, politicians, and as long as we find these minerals, it is useful. Li Wen said with his hands behind his back. He was looking at the terrain in the distance.

"The water transportation here is more developed, developed, and the difficulty of transportation is relatively small. Remember, child, that the future will require many, many pieces of iron, as you have seen. The Koreans already use iron beams in shipbuilding. Railroad tracks were laid everywhere, and the houses began to use iron. I believe that it will not be long before the demand for iron will be more and more, not only iron, but also more steel, the demand for steel will only increase, not less and less, the deposit we found today may be able to meet today's temporary needs, but in the future, the world is very big, and our burden is still very heavy. Li Wen said meaningfully as a professor.

"Hmm. Professor. I know. Regardless of politics or economic matters, we can do our own thing. Student Zhao Shan said.

"Yes, no matter what. Let's just do our own thing. Li Wen said. Li Wen knows that in the future, the demand for steel will increase exponentially, because there are too many places that need steel.

Jiaozhou, Qingcheng. Outside of an uninhabited sea.

"Da-da-da-da-da." In the distance, a small boat was moving forward with black smoke, and two huge paddle wheels were spinning on either side of the boat. There are no sails on board. But the sailing was very smooth.

"Looks like our experiment was successful." A young engineer said to a master.

"yes, it worked. Without sails, this small boat can still sail, and the next step is to make a bigger ship. With a bigger ship, you can carry more cargo. The master said.

"It's just that I feel that this small boat still has a lot of shortcomings." The young engineer said.

"For example, this paddle wheel, why don't the ships of the Qin State use paddle wheels, the propulsion propellers of their ships are underwater, and the speed is very fast, but we use paddle wheels, and when we do experiments, we found that this paddle wheel can only sail in quiet, small water, once it fluctuates greatly. Or if the waves on the sea are too big, the ship will not work. The young engineer said.

"Hmm. But there is no way, the manufacturer who makes the propeller is made. However, we have no way to drive the gear, the fit of the gear is still not good, and the waterproof device is not good, which requires the import of special sponge and sea rubber materials from Qin. We don't know how the project is at the moment, but we'd better wait. The old master said steadily.

"Well, that's what the master said. We've been more stable, and we've gone too fast before. As a result, a lot of projects are good, and the result is a waste of money. The young engineer said. South Korea's scientific and technological research and development has adopted the method of bringing the old with the new and the new innovation, that is to say. The technical experience of the old master is still in play, after all, these experiences are irreparable, and the newcomers, that is, those new engineers, they are young, they have accepted the new knowledge of the Qin State, they have new ideas, they know a lot. But they lack experience, and many times, when it comes to specific production, they will encounter all kinds of difficulties, and such difficulties are difficult for new engineers to solve, and their knowledge accumulation experience is still very small. There is little experience in solving difficult problems, but the masters have such experience.

"The wind is blowing. The waves are getting bigger. At that moment, the observer in the distance shouted loudly.

"Quick, let them in, you can't sail when the wind and waves are strong, it's dangerous." The old master shouted excitedly.

"This." Young engineers are struggling. He wanted to try the ship on this voyage.

"Why don't we give it a try?" The young engineer suggested to.

"This. It's not now to give it a try, hurry up, come back. Come back. The old master shouted worriedly. He shouted anxiously.

"Come back, call the signal back." The young engineer shouted. This is a steamship project in South Korea, with the launch of the arrow sailing boat, South Korea needs new ships to expand the sailing capacity of their ships, thinking that from the perspective of future needs, South Korea needs bigger and faster ships, and ships are their only needs, because due to the influence of the monsoon, the ships only have the opportunity to sail twice a year, but if they use ships, they will no longer be limited by the season. This huge technical advantage is very obvious, but the current steamship still has great limitations, because the technology has not been completely solved, for example, when the wind and waves are strong, they must return to the port to take shelter, because the ship cannot sail.
