Yamatai.

The next day, after completing the training of the soldiers, Li Cunxiao and Meng Jie came to the city to find blacksmiths and craftsmen with the construction drawings of the blast furnace.

They are going to start building the blast furnace now.

Strive to complete the smelting of this batch of iron ore as soon as possible.

After the craftsmen and blacksmiths studied the construction drawings of the blast furnace, they began to build.

After several experiments, the first blast furnace was finally successfully constructed.

It's just that the effect of this first blast furnace smelting iron ore is really not ideal.

"You continue to improve the blast furnace according to this drawing, and strive to build a qualified blast furnace as soon as possible, but waiting for the reward is indispensable."

Li Cunxiao and Meng Jie encouraged the craftsmen and blacksmiths.

Inspired by the rewards and interest in the new method of smelting the blast furnace, the enthusiasm of the craftsmen and blacksmiths for their work has never been higher.

Then there is the continuous construction of the blast furnace, and then the continuous adjustment and experimentation of the blast furnace.

After a period of time like this, the new blast furnace finally met the requirements described on the drawings.

"Very well, the next step is to build a lot of blast furnaces according to this shape, smelt all the iron ore, and cast it into iron ingots."

Li Cunxiao and Meng Jie, who received the news that the blast furnace had been completed, were very satisfied after seeing the smelting effect of the blast furnace.

Then they recruited the blacksmiths in the city again, as well as some people and craftsmen, to start building blast furnaces and smelting iron ore.

It took half a month in total.

The batch of iron ore purchased from Dawei has been completely smelted and cast into iron ingots.

Bai Feng, who received the news of Himiko in advance, came to Yamatai again two days later.

"Sir, the iron ingots that have been cast are here."

Himiko took Bai Feng to a warehouse, and pointed to the iron ingots that filled the entire warehouse and said to Bai Feng.

Bai Feng looked at the number of iron ingots in front of him and nodded with satisfaction.

Although the number of these iron ingots is of little significance for building railways, it is still sufficient for the steam engine production line and the improvement of steam trains by craftsmen such as ploughing pillars.

"Well, then I will bring this batch of iron ingots back to Hanzhong first."

After Bai Feng waved his sleeves, all the iron ingots in the warehouse disappeared.

These iron ingots have been sent back to the warehouse in the R&D center by Bai Feng.

Li Cunxiao and Meng Jie, who received the notification from Himiko, also came out of the warehouse at this time, met Bai Feng together, and reported to Bai Feng about the construction of armor and weapons.

"Sir, these 20% iron ingots are enough to make fifty pairs of armor and a hundred swords..."

Li Cunxiao and Bai Feng reported on the number of weapons and armors they had built, and then Meng Jie reported to Bai Feng the results of recent training.

"Well, just keep going."

"And usually let the soldiers familiarize themselves with the sea."

Finally, before Bai Feng left Yamatai, he explained to Meng Jie.

Of course, the original people of Yamatai did not need to be familiar with the sea, but the soldiers of the original Ugo people who migrated to Yamatai from the Nanzhong Mountains naturally needed to be familiar with the sea.

Otherwise, if you get seasick as soon as you go out to sea, how can you fight a war?

Not long after Bai Feng left Yamatai, the Great Wei Navy, led by Wenpin, the navy general who returned from Yamatai, also docked at the port.

After the ship docked, Wen Pin rested for a night and set off for Yecheng, preparing to report to Cao Cao the transaction with Yamatai this time.

Yecheng Palace.

Cao Cao was listening to Wen Ping's report at this time.

"Your Majesty, the queen of Yamatai once said to the last general that Yamatai is very short of iron ore, and the people don't have an iron pot in their homes..."

After reporting to Cao Cao what he had seen and heard in Yamatai, Wenpin waited for Cao Cao to make arrangements.

Cao Cao saw that Yamatai was so short of steel, and he was much more confident about occupying Yamatai.

However, if Yamatai is not rich in mineral resources, it is necessary to carefully calculate the cost of occupying Yamatai.

Don't wait until you finally occupied Yamatai to find out that it was a loss-making business.

"In addition to the fact that Yamatai is not rich in minerals, what is the area of ​​land that can be used for farming?"

Then Cao Cao asked Wenpin.

"Reporting to Your Majesty, I only know from the Queen of Yamatai that the iron ore here is not rich, but there should be a lot of silver ore."

"Silver is used for this transaction. As for the land area that can be cultivated in Yamatai, it is inferred from the number and appearance of the people in the city that the minister sees, and it is enough to maintain one to two million people and be able to eat enough.. …”

Afterwards, Wenpin explained to Cao Cao one by one based on his observations and some speculations.

There are silver mines and the area of ​​arable land is acceptable.

Cao Cao noticed these two points from Wenpin's description.

From this point of view, the occupation of Yamatai is still profitable for Da Wei.

And in the future, Yamatai can also be used as a training and supply location for the Great Wei Navy at sea.

In general, as long as Yamatai is occupied, Da Wei should not lose money.

"Since this is the case, then the transaction with Yamatai should not be interrupted, at least twice a year."

"And in the future, you can bring some businessmen to Yamatai and let them set up shops in Yamatai to collect information about Yamatai for us."

Finally, Cao Cao told Wen Pin.

Now that the navy of the Great Wei Dynasty has just formed its combat effectiveness, Cao Cao will not use force to capture Yamatai at this time.

If it is possible to allow Yamatai to return to the Great Wei in the midst of continuous trade, then it is naturally the best situation.

At that time, the people of Great Wei will slowly migrate to Yamatai, and officials will be stationed in Great Wei, so that after more than ten years, Yamatai can completely become part of the territory of Great Wei.

Cao Cao planned everything perfectly.

It's a pity that he still doesn't know that Yamatai is already Bai Feng's back garden.

In Bai Feng's plan, Yamatai will become the capital of maritime trade, constantly relying on maritime trade to obtain resources from all over the world and support Bai Feng's development.

Fortunately, Cao Cao was not in a hurry to use force, otherwise, even if Yamatai would not be occupied under Bai Feng's intervention, his vitality would be greatly damaged.

This will have a great impact on Bai Feng's plan.

......

Bai Feng, who returned to the R&D center, gave the iron ingot just sent from Yamatai to Gengzhuzi for distribution.

At the same time, I also learned about the improvement of the steam train.

Now Geng Zhuzi and Li Tiedan are developing a more powerful steam engine to ensure that the steam train has enough power.

"Let go and do it, don't worry about the lack of steel!"

Finally, Bai Feng said confidently to Geng Zhuzi.
