In addition, the raw materials for making the original solution were already cheap, so the cost of a bottle of floral water was gradually reduced to just a few cents as mass production increased.

In addition, there were a few coins for the labor cost of transporting each bottle of floral water, and another ten coins out of the remaining ninety coins were distributed among Zhao Qingzhu and Zhu Yuntong. The last eighty coins went to the imperial court.

In this way, a month later, the floral water industry had been established in almost every part of the Ming Dynasty.

After all, the weather is hot right now, and this bottle of floral water can serve many purposes in this hot summer, so it is naturally very popular and many people like to buy it.

Even relatively ordinary families will buy a bottle and use it sparingly.

In this way, an ordinary county town could sell about 100,000 bottles, which would generate an income of 10,000 taels of silver.

The Ming Dynasty had nearly a thousand counties, and in just one month, it earned tens of millions of taels of silver.

This is what's left after deducting costs, labor, and the small portion taken by Zhu Yunwen and Zhao Qingzhu.

All of this money was deposited into the Ministry of Revenue's treasury, instantly reviving it.

After all, ten million taels of silver is by no means a small amount. It can allow the Ministry of Revenue to pay all the idle project funds and still have a lot left over.

In addition, the floral water is still being sold continuously, and the money collected from various places is still being deposited into the national treasury.

At least in the short term, the national treasury has enough money.

However, once summer is over and autumn and winter arrive, the effect of floral water is not so obvious, which will reduce income for a period of time.

After witnessing the benefits that state-owned industries could bring to the national treasury, Zhu Yuanzhang repeatedly urged Zhu Yunwen to find more ways to establish more state-owned enterprises.

Zhu Yunwen had supported this before, since making money for the court was definitely a good thing.

So when Zhu Yunwen had nothing to do, he began to ponder.

Finally, he came up with a good idea: to make some bicycles and tricycles.

After all, Daming Road is so well-maintained now, it's all paved with cement.

Wouldn't it be a waste not to upgrade people's means of transportation?

Besides, Zhu Yuntong had told Zhao Qingzhu before that he would invent some interesting things, so wouldn't it be perfect to make bicycles and tricycles now?

In any case, Zhu Yunwen didn't have any major issues to deal with during this period. The country was peaceful and stable, the court was wealthy, the people had land, and the whole Ming Dynasty was in harmony.

Zhu Yuanzhang and Zhu Yunwen had no worries. The conditions were unprecedented, and it would be a waste of this rare opportunity not to create some strange and unusual things.

After making up his mind, Zhu Yunwen began to study the blueprints for the bicycles, tricycles, and other vehicles he wanted to make inside the Eastern Palace.
