Yang Feng boarded a ship in Chengdu and went down the Minjiang River.

At this time, the core area of ​​Yizhou was Shu County, plus parts of Guanghan and Jianwei County. It was actually a fan-shaped irrigation area radiated from Dujiangyan. This was the core of the Tianfu Kingdom. It relied on this ancient water conservancy facility. This land was irritating from people to the water and drought. Even with the crops and agricultural technology level of this era, this land, which was actually less than 10,000 square kilometers, also supported more than 2 million people during the heyday of the Eastern Han Dynasty, and the population on the household registration did not include slaves and hidden households.

But it is much different outside these three counties.

But there are special ones.

The Yizhou Governor's Ministry also has a county with a population of less than Shu County, although its number of households is not as large as that of Shu County, which is in a place that modern people must not imagine.

Yongchang County.

The capital of Baoshan, Yunnan is half in Yunnan and half in northern Myanmar, with a population of 1.8 million.

I have to say that there are too many things that are forgotten in modern times, such as the Jiaozhi County of the Han Dynasty, which is 700,000 Hanoi, which is eight times that of Guangzhou during the same period.

Yang Feng's tour was not only to show his miracles or show off along the way, but also a new technology seeder, constantly spreading various agricultural technologies, water conservancy construction technologies, and especially the utilization technology of various fertilizers. At this time, the fertilizer was limited to human and animal manure, so the green manure that appeared in the Wei, Jin, Southern and Northern Dynasties, compost from the Song and Yuan dynasties, river mud, fire manure, and even ashes dipped in the Ming and Qing dynasties, and even the technology of lime to improve the acidity of the land was taught. Since he could not dig bird dung for the time being...

In fact, it can't get here even if you dig it.

Then he can only use these techniques to make some small cheats for farmers.

As for the good varieties...

He really has no choice.

The only thing he can do is to find a way to get cotton, but this takes time. After all, he has to get it slowly from India and Egypt. At this time, maritime trade is not good, and he has to rely entirely on the Silk Road. However, if he builds large seaships and sails for a long time, he should be able to speed up, such as building ships from Yongchang County to Yangon to open a colony.

In addition, there is a road through the Wild Man Mountain to Assam in Yongchang County.

But this is all for the future.

What he can help Liu Bei now is to teach him to open a salt well.

At this time, there was only one Fushun. The salt of Fushun was mined in the period of Emperor Zhang of Han. The world's first well Dagong well also appeared. However, it was not until the Northern Zhou Dynasty that it truly exerted its power. As for Ziliu Well, it was very late and it began to appear in the Ming Dynasty. What Yang Feng needed to do was to teach Liu Bei to expand the scale and continue to dig deeper and then use natural gas to cook salt. This set of things and things were played well in Sichuan and even around him, especially for controlling the surrounding mountain villagers. Ge Luofeng tried hard to expand northward, but in fact the purpose was to make several salt wells in Sichuan. For modern people, it was difficult for modern people to understand how crazy the mountain villagers in the southwest region were at this time. Controlling the salt well could control their lifelines.

Of course, this thing must be the official business.

The entire salt industry in the Han Dynasty was the official business, which was created by His Majesty the Emperor, of course, which was the Emperor's property. Liu Bei was just managing it for him.

There is also the sugar industry.

Sichuan can grow sugarcane in large quantities, and the production method of sugar is given to Liu Bei, so it doesn’t need to be officially launched. It is considered to give Liu Bei and his confidants the source of wealth. Emperor Yang of this era was actually not interested in controlling the economy. What he needed was to solve the many basic needs of the people, and the output of food, clothing, salt, sugar, etc. soared. He was not interested in making money or not. He didn’t consider these things at all now.

And of course, it's coal mining.

Digging coal, coking, and iron smelting, all of this set is for Big Ears. Of course, this is still the property of His Majesty the Emperor, and iron smelting is also the official camp. Since it is the official camp, it is also the Emperor's.

There are also copper mines, which are located in the mountains of Pengxian next to Chengdu. They started mining during the Song Dynasty. At this time, Da Er Duo also went to mine. Anyway, the mining was mined and returned to the emperor. At most, the emperor issued an order to reward them for minting money here and then handing over some of the minted money. There is also gold digging. Jinsha River was an important gold production place since the Song Dynasty, so Da Er Duo and others rushed to rush gold, which just lured them to strengthen their control over Yunnan. At this time, several counties in Yunnan were in a separatist state, and Liu Bei was just like a vassal. Local tyrants controlled the Han people and the Yi King controlled the mountain people.

The most famous of them are Yong Kai, Meng Huo and Gao Ding.

Yongkai was a Han native, and Yizhou County was a local tyrant in Kunming.

Meng Huo's rebellion was actually the temptation of Shi Xie to surrender to Sun Quan while Liu Bei's death. Then he incited Meng Huo again because of the familiarity of the situation. Meng Huo went to incite the Yuewu, such as Gao Ding, and eventually formed a major rebellion in the south of Shu Kingdom.

Of course, it is mainly because Liu Bei has too weak control over this area.

It would be different if there was gold.

Yang Feng went down the Minjiang River like this, constantly giving Liu Bei and Zhuge Liang a golden finger along the way. At the same time, he encountered dangerous shoals and reefs that were blocking him, so he could solve the problem that the water transportation from Chengdu to the Yangtze River was stable. Finally, in early February of the 21st year of Jian'an, Jiangzhou County, which was the county seat of Ba County, was Chongqing, and then continued down the Yangtze River and arrived at Yufu quickly.

Kuimen.

"Your Majesty, have you sent someone to call them over?"

On the warship docked on the river bank, Liu Bei asked the emperor carefully that the water level of the Yangtze River had not risen yet, and not far away, there was a narrow river surface standing between the two mountains.

"unnecessary!"

Yang Feng said.

After saying that, he flew up.

The common people screamed and bowed, while the sailors and officials who were escorting the warships on both sides of the shore turned a blind eye, or were used to it. His Majesty the Emperor had too many miracles, which was shocking to the local people, but they had watched them many times along the way, and had long been aesthetically exhausted. However, it was obvious that His Majesty the Emperor's flight distance today was a bit long. He walked with his hands behind his back to the wind like Nie Feng, and then landed on the Yanqiu pile accurately.

The next moment, the huge rocks under his feet continued to turn into fine sand like wind.

This stone is not big.

And the most important thing is that it is large and small because of the years of river water, and it is like a huge fig that is half a piece of submerged in water. Therefore, Yang Feng does not need to get in like dealing with the small islands of Sanmenxia. Although his current energy control range is not enough to completely decompose at once, it is enough to divide it into two times. With the desertification and collapse of the Yanhui pile, the huge fig was cut in half in a blink of an eye.

Then the Emperor, who disappeared from the water, suddenly flew up like a hidden dragon, with countless splashes of water, and then landed on the remaining half.

Soon this half disappeared.

The Yanhuadui, which blocked the reincarnation of the Yangtze River channel countless times, completely disappeared, turning into a smooth stone platform three meters underwater. The surface of Kuimen River suddenly became clear, and countless ship workers were screaming madly there. Although Yang Feng only dismantled a small rock, for them, the nightmare of generations disappeared.

Yang Feng, who was floating in the air, looked down majesticly below.

Liu Bei and others hurriedly knelt down to cooperate with His Majesty's pretentious behavior.

Yang Feng then slowly fell down.

"Go ahead, keep moving forward!"

His Majesty the Emperor waved his hand and said.

Then the fleet passed through Kuimen in a mighty manner.

Just three hours later, the fleet suddenly appeared in the sight of the people of Wushan. Then the Wushan City was in chaos, including the Eastern Wu warships on the shore. In this chaos, Yang Feng's ships ignored them and left. When Gu Yong, Lu Meng and others came out of the city, they happened to see the tail of the fleet moving away from their sight.

These two men were stunned.

After they woke up, they boarded the ship as fast as possible to chase after, but it was useless to chase at this time.

There is no obstacle to the Yanqi pile moving forward.

At least there was no obstacle for the fleet that was going downstream. It was not until the time when Zigui was approaching, but after his Majesty the Emperor walked a few trips in the middle of the river, all the small reefs were cleaned up, and a passage with a depth of nearly three meters and a width of more than twenty meters was opened. Just when Lu Meng and others were chasing all the way, they finally saw His Majesty Emperor's fleet, the fleet had set out again, because the entire channel hydrology changed completely after Yang Fengtong opened this passage. Lu Meng's fleet pilot ship went downstream as usual, but it hit the shallows.

Of course, Yang Feng didn't know about this.

His fleet went downstream and reached the next dangerously blocked Qingtan. The biggest problem here is that the water level drops during the dry season, and the reefs hinder the waterway, which eventually forced all the big ships into a channel that was not much wider than the length of the hull. It was also an S-shaped channel. Moreover, the bottom of the channel was uneven due to the rock bottom, which formed a significant water level drop...

Of course, it is not worth mentioning to meet His Majesty the Emperor.

Yang Feng still walked back and forth a few times.

Then he dug out a special passage at the bottom of the rocky river, blocking several other useless water flows, forcing the river water into this passage, and then the dangerous shoals became a thoroughfare. The fleet went down one after another to meet the sunset to reach the last Ghost Gate Kongling Beach. This place was also huge rocks crossing the middle of the river. Even the steamboats were sank. The bow of the ship must drive directly towards the huge rock with the courage to hit the rocks, so that it could be pushed by the water flow to automatically and safely pass through the rocky waterway. Later generations wrote three big words on this huge rock to remind the ships passing through...

Come to me!

But all obstacles are a scumbag when encountering the emperor!

His Majesty the Emperor was trembling and worshiping the boatmen on a group of upward civilian boats, and directly turned the huge stone and the small reefs around it into slag and disappeared into the river.

"Let's go and see the style of Yunchang!"

Yang Feng, who returned to the ship, said.
Chapter completed!
