Although Wei Minsheng has knowledge, technology and resources far beyond this world, everything he obtains through this world will not bear the imprint of history, so he can't treat some things in this world as antiques and make a fortune in the real world.

Although there should be the existence of golden silk nanmu in these deep mountains, it is impossible to sell it directly, because these are hundreds of years old new materials, and their legal sources cannot be explained at all.

Under such circumstances, apart from those ordinary woods, the only things in this world that could bring Wei Minsheng a huge income in a short period of time were medicinal herbs, gold, and silver.

Judging from the purchase of medicinal materials some time ago, a lot of ordinary medicinal materials were purchased, but not many precious medicinal materials were received, because this vicinity was not the origin of those precious medicinal materials.

And as far as Ziguicheng is concerned, there is no big family.

Because it is located at the crossroads of the three kingdoms, it can ignite a war at any time, and it is not a place for a family to rest.

The currency circulating in the market is mainly copper coins, so Wei Minsheng only collected more than one catty of gold and more than ten catties of silver.

Those shiny copper coins are of no use to Wei Minsheng at all, and they are "things made up by liars" in the world, and the shape is "imitation" well, but you still make these things old, such a smooth surface doesn't look like an ancient thing.

Therefore, Wei Minsheng hit the idea on those cities along the Yangtze River, hoping to exchange some exquisite modern handicrafts from those big households, at least to support the gold shops in the real world.

Although more than a dozen official members of the Huaxia Kingdom have learned how to operate the transformed large cargo ship under the leadership of Wei Minsheng, such a tonnage iron ship has never sailed in the Yangtze River, and how deep and wide the channel is needs to be carefully measured.

This is best done by the boats, which are more agile on the river, and whose owners know more about the nearby waterways.

Before figuring out all the conditions of the waterway, Wei Minsheng was still not sure that they would be relieved to send the big iron ship out to promote the force of the Huaxia Kingdom.

Even the two cargo ships that were purchased later to provide fuel did not dare to let them sail in areas where the depths of the channels were not clear.

According to the current capacity of Huaxia Kingdom, if the grounding is damaged, the loss will be too great, and it is impossible for Wei Minsheng or a few subordinates with shared space to follow wherever these ships go.

Therefore, after Huaxia used those scrapped cars to produce its own water transportation platform with a power system, Wei Minsheng decided to let them test the waterway between Zigui and Yiling for a period of time to test its safety before deciding the time to develop eastward.

In a world of extreme food scarcity, food can exist almost as hard currency.

Under such special conditions, Wei Minsheng, who could easily obtain a large amount of cheap grain and had great destructive ability, could completely use grain as a weapon of the Huaxia State and conquer the cities on both sides of the lower reaches of the Yangtze River by means of trade.

Huaxia urgently needs to absorb more human resources from this world to meet the growing demand for development.

Although Ziguicheng is the closest in terms of distance, due to the natural danger of the Yangtze River, and the surrounding human resources have long been evacuated by Huaxia, there is no development significance in this direction for the time being.

Huaxia does not have the ability to build the Yangtze River Bridge, and if it relies entirely on water transportation, Ziguicheng will not be able to adapt to the large-scale flow of people and materials.

Therefore, the current meaning of Ziguicheng's existence is to serve as a separation belt between Wu and Shu, to avoid war and continue to bleed this already scarred world.

In the relevant historical records, the battles of the Three Kingdoms period were often claimed to be millions of troops, but in fact there was a very large amount of water.

In the heyday of the Shu Kingdom, there were only about 100,000 soldiers, and the total population was less than one million.

At the height of the Wu Kingdom, there were no less than 300,000 soldiers, and the total population was only between more than 2 million and 3 million.

Wei occupied the richest Central Plains at that time, with 600,000 or 700,000 soldiers at its peak, and a total population of only about 4 million.

The ratio of soldiers to civilians in the three countries is already quite high, basically seven or eight ordinary people have to support one soldier, not including the royal family, officials, state institutions, daily expenses, etc.

Such a high ratio of soldiers to residents means that young and middle-aged men have basically disappeared from the civilian population, and most of them have appeared in the army.

Although the total population of Shu is relatively small, the reputation of the country of abundance is not covered, as long as there is no large-scale war, the fertile land of the CD Plain is enough to ensure the recuperation and recuperation of millions of people.

Under such circumstances, Zigui is no longer the focus of the development of Huaxia, but due to the particularity of its geographical location, it is no problem to temporarily accept the displaced people, civilians and some merchants who have taken refuge in Shu.

The extreme lack of human resources has become the biggest problem hindering the pace of development of Huaxia, forcing Wei Minsheng to advance some expansion plans, so Wei Minsheng has the idea of taking Jiangling as soon as possible.
