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

At this time, the core area of Yizhou is Shu County plus Guanghan and Qianwei two counties each part, in fact, Dujiangyan radiates out of a fan-shaped irrigation area, this is the core of the country of abundance, relying on this ancient water conservancy facilities, this land is drought, do not know hunger, even with the level of crops and agricultural technology in this era, this land is actually less than 10,000 square kilometers of land, in the heyday of the Eastern Han Dynasty also fed more than two million people, and refers to the population on the household registration does not include slaves and hidden households.

But outside of these three counties, it is much worse.

But there are special ones.

There is also a county in the Yizhou Thorn History Department that is not as large as Shu County, but the population is more than that, in a place that modern people must not imagine.

Yeongchang County.

Baoshan, Yunnan, half of which is in Yunnan and half is in northern Myanmar, has a population of 1.8 million.

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

Yang Feng's tour is not only to show his miracles or pretend to be forced along the way, he is also a new technology planter, constantly spreading all kinds of agricultural technology, water conservancy construction technology, especially the utilization of various fertilizer technologies suitable for this era. At this time, fertilizer was still limited to human and animal manure, so the green manure that appeared in the Wei, Jin, Southern and Northern Dynasties, the compost of the Song and Yuan dynasties, river mud, fire manure and even the ashes dipped in the roots of the seedlings in the Ming and Qing dynasties were all taught, and even the technology of lime to improve the acidity of the land was also taught, since it was impossible for him to dig guano for the time being......

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

Then he can only use these techniques to open up a little hanging for the farmers.

As for the good breed......

He really can't help it.

The only thing he can do is to find a way to get cotton, but this will take time, after all, it has to be slowly obtained from places like India and Egypt, and at this time the maritime trade is not good, and it has to rely on the Silk Road, but if he builds large sea ships to sail long, he should be able to speed it up, such as shipbuilding from Yongchang County to Yangon to open a colony.

In addition, Yongchang County originally had a road through the Savage Mountain to Assam.

But that's all for later.

Now what he can help Liu Bei is to teach him to open a salt well.

Sichuan Yanjing at this time only one Fushun, the Han Emperor Emperor era Fushun's well salt began to mine, the world's first well Dagong well also appeared, but it was not until the Northern Zhou Dynasty that the power was really exerted, as for the artesian 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 while continuing to dig deep and then use natural gas to cook salt. This set of things is good to play Sichuan and even the surrounding do not have to worry about the problem of salt, especially for the control of the surrounding mountain people is very effective, when Ge Luofeng desperately expanded to the north, in fact, the purpose is for a few salt wells in Sichuan, it is difficult for modern people to understand how crazy the mountain people's desire for salt in the southwest is at this time, and controlling the salt wells can control their lifeline.

Of course, this thing must be a government camp.

The salt industry of the entire Han Dynasty was all official, which was made by His Majesty the Emperor, of course, it was His Majesty's industry, and Liu Bei was just managing it for him.

There is also the sugar industry.

Sichuan can grow a large number of sugarcane, and hand over the manufacturing method of white sugar to Liu Bei, which does not need to be run by the government, it is a source of money for Liu Bei and his cronies, saying that Emperor Yang of this era is actually not interested in controlling the economy, what he needs is to solve a lot of basic needs of the people, what he needs is that the output of clothing, food, salt, sugar and so on has skyrocketed, and he has nothing to worry about making money or not, and he doesn't think about these at all now.

And, of course, digging coal.

Coal mining, coking, and iron smelting, all of which are put to the big ears, of course, this is still the property of His Majesty the Emperor, and iron smelting is also an official camp, since it is an official camp, of course, it is also His Majesty's Emperor's.

In addition, there is a copper mine, there is a mountain in Peng County next to Chengdu, which began to be mined in the Song Dynasty, at this time let the big ears also go to mine, anyway, the mining is returned to the emperor, at most the emperor ordered them to be rewarded here that they can mint money, and then hand over a part of the money. There is also gold panning, the Jinsha River has been an important gold producing area since the Song Dynasty, so let the big ears they pan for gold, just to lure them to strengthen their control over Yunnan, at this time several counties in Yunnan are like a partition, for Liu Bei is just similar to a vassal, the local Haoqiang controls the Han people and the king of Yi controls the mountain people.

The most famous of these are Yonghong, Meng Huo and Gao Ding.

Yonghong is a Han Chinese, and Yizhou County is a strong place in Kunming.

Meng Huo's rebellion was actually his inducement to take advantage of Liu Bei's death to join Sun Quan under the lure of Shixie, and then he instigated Meng Huo because he was familiar with the situation, and Meng Huo then instigated Gao Ding and these Yue Wangyi, and finally formed a great rebellion in the south of the entire Shu State.

Of course, the main reason is that Liu Bei's control over this area is too weak.

It would be different if there was gold.

Yang Feng went down the Min River in this way, and kept opening the golden fingers to Liu Bei and Zhuge Liang along the way, and at the same time he encountered the dangerous shoals and reefs that hindered him, and he cleaned them up by himself, which was also regarded as solving the problem of stabilizing the water transportation from Chengdu to the Yangtze River, and finally arrived at the county of Ba County in early February of the 21st year of Jian'an, that is, Chongqing, and then continued down the Yangtze River all the way down the river to Yufu soon.

Kuimen.

"Your Majesty, did you send someone to call them over?"

On the warship docked on the riverbank, Liu Bei cautiously asked His Majesty the Emperor, at this time, the water level of the Yangtze River had not yet risen, and not far away stood on the narrow surface of the river between the two mountains.

"No, you don't!"

Yang Feng said.

After saying that, he flew up.

Those ordinary people screamed and bowed, and the sailors and officials escorted by the warships anchored on both sides of the strait turned a blind eye, or they were used to seeing it, His Majesty the Emperor had too many miracles, which were full of shock for the local people, but they didn't know how many times they had seen it along the way, and they had already been aesthetically fatigued, but it was obvious that His Majesty the Emperor today had a long flight distance, and walked against the wind with his hands behind his back in the Kui Gate, and then landed accurately on the pile.

The next moment, the boulder under his feet continued to turn into fine sand and collapse like wind erosion.

The stone is not big.

And the most important thing is that it is large and small because of the perennial river water, just like a huge fig half submerged in water, so Yang Feng does not need to get into it like dealing with those small islands in Sanmenxia, with his current energy control range, although it is not enough to decompose all at once, but it is enough to divide it into two times, with the desertification and collapse of the pile, this huge fig will be cut in half in a blink of an eye.

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

Soon this half was also gone.

The pile that blocked the countless reincarnations of the sun and the moon in the Yangtze River channel disappeared completely, turning into a smooth stone platform three meters underwater, and the river surface of Kuimen suddenly opened up, and countless boatmen screamed like crazy there, although Yang Feng only decomposed a small rock, but for them, the nightmare of generations disappeared like this.

Yang Feng, suspended in mid-air, looked down majestically.

Liu Bei and the others were busy kneeling down to cooperate with His Majesty the Emperor's pretense.

Yang Feng slowly fell.

"Let's go, move on!"

His Majesty the Emperor said with a wave of his hand.

Then the fleet roared through the gate.

Only three hours later, this fleet suddenly appeared in the field of vision of the people of Wushan, and then there was a lot of chickens and dogs jumping in Wushan City, including those Dongwu warships on the shore were also the same chickens and dogs jumping, in this chaos, Yang Feng's ships didn't even pay attention to them and left, and when Gu Yong, Lu Meng and others came out of the city, they just saw the tail of the fleet in their field of vision.

The two men were dumbfounded.

When they came to their senses, they boarded the ship as fast as they could and chased after them, but it was useless to chase them by this time.

There was no obstacle to the progress of the pile.

At least there was no obstacle for the fleet going down the river, and it was not until the time of Zigui that it encountered a real dangerous beach, but after His Majesty the Emperor walked a few times in the center of the river, all the small reefs were cleared, and a passage with a depth of nearly three meters and a width of more than twenty meters was directly opened. Just when Lü Meng and the others, who were chasing all the way, finally saw His Majesty the Emperor's fleet, this flotilla had already set off again, because the hydrology of the entire channel had completely changed after Yang Feng opened this channel, and Lü Meng's fleet pilot ship went down the river according to the previous habit and crashed headlong into the shallows.

Of course, this Yang Feng doesn't know.

The biggest problem here is that the water level drops during the dry season, and the reef comes out of the water to obstruct the channel, and finally forces all the big ships into a channel that is not much wider than the length of the ship, and it is also an S-shaped channel, and the bottom of the channel is obviously dropped because of the unevenness of the rocky river bottom......

Of course, meeting His Majesty the Emperor is not worth mentioning.

Yang Feng still walked back and forth a few times.

Then he carved a special channel in the rocky bottom of the river, and at the same time blocked several other useless streams, forcing the river into this channel, and then the dangerous shoal became a thoroughfare, and the fleet rushed down to the last ghost gate Guangangling beach at sunset. Here is also a huge rock across the middle of the river, this ghost place is the steamship has been hit and sunk a pile, the bow of the ship must be facing the boulder with the courage to hit the courage to drive over, in order to be pushed by the current automatically away from the moment of collision and safely through the rocky channel, later generations in order to remind the passing ship, on this huge rock written three big characters......

Come to me!

But all dangers and obstacles meet the emperor is scum!

His Majesty the Emperor trembled in worship to the shipwrights on a group of people going up, and directly let this boulder and the small reefs around it turn into scum and disappear into the river.

"Let's go, go and see Yun Chang's demeanor!"

Yang Feng, who returned to the ship, said.

Then his fleet went straight to Gangneung through Kongling Beach.
