However, the reality is so cruel, the annual tax revenue of a Haizhou is only one million guan, and the imperial court built an official road from Chang'an to Tongguan is more than one million.

However, Haizhou is still ranked third in Datang.

Of course, there are all sorts of other factors involved, and without those subsidies for Tokaido, Haizhou's income would have been even higher.

But for those who control the state, these can only be regarded as drizzle.

These subsidies and short-term short-term income shortages are not meaningless, and other investments are by no means wasteful.

Eight counties were directly involved in the road construction, and nearly 20 counties were responsible for allocating manpower to help with transportation and logistics.

All of these counties involved in road construction saw their revenues increase by about 10 percent last year compared to before.

In other words, the imperial court built a road, and then within last year, it was equivalent to making the imperial court have three more counties of income.

And this is not a one-time income, the road is here, and it will drive other aspects of income in the future.

It can be said that this is a matter of great profits, and the household department has a refined calculation, giving a forecast of the increase in the fiscal revenue and expenditure of each county in the next few years, and the summary result is that if the status quo can be maintained, about six or seven years, the imperial court can recover the investment in this road.

But this calculation is very inaccurate, or in a way, very inaccurate.

Because they are very conservative in their forecasts, although they themselves think they are very bold predictions, based on annual increases of 10%.

Li Shimin is really excited now, the Tang Dynasty has undergone earth-shaking changes, and the life of the imperial court is getting better and better.

Although there was a large amount of gold and silver, which had previously only been slowly invested through the bank, it was now possible to spend money on infrastructure such as building roads.

And in order to avoid a large amount of money entering the market in a short period of time, the imperial court was also cautious in road construction planning.

Just because there are enough people, you don't start building dozens of roads at the same time.

"How did these merchants' goods get here?" Li Shimin asked suddenly.

"Some small businesses often choose to open workshops here, and then collect some raw materials in the surrounding counties, and some do not, then go to farther places to buy, the specific transportation depends on the actual situation, the west and the north come by land, and the south comes according to the distance to decide whether to take the water route or the land route.

However, some large businesses usually choose to take the waterway, although the ship goes slower, but the cargo capacity is large, each has its own advantages and disadvantages! The Governor of Haizhou replied cautiously.

"Isn't that going around in a big circle?" Li Shimin frowned slightly.

He knew this waterway, first went to Yangzhou by the Grand Canal, then took the Yangtze River estuary through the waterway to enter the sea, and then went north along the coast to Haizhou.

If it is from Luozhou, it will take 20 days to say the least, but now, don't think about it if you don't have 25 days.

This waterway has become one of the busiest transportation arteries in the Tang Dynasty, so the imperial court has to send additional personnel to manage the river.

If it is not properly managed, there will be a picture of boats crowding on the canal.

"There is no way to go around, although Shanyang Wharf is only more than 200 miles away from Haizhou, but the ship can carry too much goods, and unloading the ship from there is land transportation, whether it is time, manpower, or capital, it is much more than the ship going around in a circle." The governor of Haizhou said depressedly.

They are not stupid, and it is not the government's turn to think about this kind of thing first.

The merchants were more shrewd than the other, and they had already calculated the cost of the various journeys.

In the end, I found that although it was time-consuming to walk around by water, it was the most cost-effective way to do it.

It is precisely because more and more people are discovering this truth that the shipping business on the canal is so busy.

Of course, Li Shimin also knows this helplessness, but he also knows that this will cause a certain waste of resources.

Now that all the water resources are used for these transportation operations, the imperial court will inevitably have a certain impact on some of the layouts in other regions.

Relying on road construction is a solution, but so far, Li Shimin has found that road construction is not a panacea, and the biggest problem is that the load of a carriage is limited.

For example, the steam engines and boilers manufactured by the Haizhou steam engine workshop could not be transported by land, but could only be transported to Luozhou by water, and then sent to Chang'an by way.

These things are too heavy for ordinary vehicles to carry.

In the past few years, Li Shimin has also realized a truth, if you want to develop rapidly, the imperial court must learn to use various resources and strive to maximize its value.

It's not that you need to reach the peak in a certain aspect, which will only lead to a situation where the boss will starve to death and the second child will starve to death.

Therefore, after learning about the actual situation in Haizhou, Li Shimin had the idea of building a road in his heart.

Of course, this is not absolute.

Similarly, it was at this time that Li Shimin really realized Li Yuanjing's foresight.

It seemed like a joke back then, but what about now?

Li Shimin once again saw his short-sightedness, if he could support this decision back then, even if it still can't solve the problem now, I'm afraid it will be able to solve the problem in the near future, right?

The craftsmen of the Tang Dynasty could not build boilers, steam engines, and the divine battleship of the Tang Emperor that was blown by the crown prince.

Li Shimin, who had something on his mind, hurriedly ended his trip to Haizhou, and the trip that he had originally planned to stay in Haizhou for a few days was also canceled, and he went directly to the naval barracks dozens of miles away with the convoy.

Datang has two navies, one is the navy under Li Yuanjing, which is adapted from the original Haizhou Army, and so far, there is no ship under the command of this navy.

The other is the navy in the hands of the imperial court, which is adapted from 20,000 former Haizhou troops and 10,000 newly recruited soldiers, inheriting all the warships of the Tang Dynasty, including the fleet that Li Yuanjing went to sea before, and even inherited the 500 stone steam engine ship.

When he came to the naval camp, the sky had already darkened, and Li Shimin could only roughly observe the steel giant ship through the firelight on the Tang Emperor.

However, the lights were so weak that you could vaguely see the moving figures of soldiers patrolling with glass lampshades on them.

"What about King Zhao?" When he saw that only Li Jing greeted him, Li Shimin asked a little angrily.

"Your Majesty, King Zhao is in the dock next door, these times King Zhao almost only sleeps less than three hours a day, and stays there all the rest of the time." Li Jing said that he also had to admire Li Yuanjing's perseverance.
