The traffic in this era is really backward!

Around Sichuan, it is even more "difficult to go to the blue sky"!

This kind of terrain is much easier to defend than the plains!

In Wang Li's view, the passage into Sichuan in three directions only needs to hold the Yangtze River in the east and Hanzhong in the north!

The Yunyang and Baihe lines in the northeast are crisscrossed by Shenlongjia, Wudang Mountain and Qinling Mountains!

The only trail that almost runs through the primeval forest!

This passage into Shu is on the map of the Qin and Han dynasties!

However......

In the Battle of Xiangfan during the Three Kingdoms, after the Wu army cut off the waterway of the Yangtze River, Guan Yu traveled northwest from the direction of Maicheng, just to retreat to Shuzhong from this road!

It's a pity that he thinks this path is too simple!

Even hundreds of years later, the Japanese invaders, who had planes and tanks, were not able to attack Sichuan from this road!

From beginning to end, after 14 years, the Japanese army failed to attack Sichuan from any way!

In the era of the late Ming Dynasty and early Qing Dynasty, with the danger of Sichuan, coupled with reinforced concrete and cannons, it was easy to prevent Huang Taiji!

Hey?

Just now, south of Wudang Mountain, what is the name of that big mountain?

Belch...... It seems like...... It seems to be a dragon frame!

I'll go!

It's Shennongjia!

The giant panda that has never been found is probably here!

Well, there definitely is!

Whoever is there, hurry to this location to find it, and you will definitely find the giant panda!

"Factory, you always want to find giant pandas, what's the use?"

"Isn't the mount of Emperor Chiyou a giant panda!

One day, the factory will also ride a giant panda on the expedition, isn't it very popular?

Zhuge Liang in the Three Kingdoms era, when he went on the expedition, he took a four-wheeled car!

Compared with the four-wheeled vehicle and the giant panda, which one is popular? ”

"Factory father, what's the use of just "pulling the wind"? Chi You and Zhuge Liang, aren't they all defeated by others? ”

"Damn!"

Wang Li's face is full of iron!

Song Zhe saw that the situation was not good, so he quickly found an excuse and slipped away.

……

If history has not changed, if history has not been tampered with, it may be written in the history books of later generations that many major events occurred from May to July of the seventh year of Chongzhen (1634 AD).

In addition to the siege of the thieves in the Carriage Gorge and the second invasion of Huang Taiji, there was also an unprecedented "population migration".

This migration was purely accidental!

A few months ago, 50,000 young and strong people from Shanxi returned to Shanxi via Huguang and Henan with relief food.

This was the expiration of the five-year contract, and the West Factory fulfilled its original promise to allow them to return to their hometown;

Although these people who returned to their hometowns did not wear gold and silver, each of them was glamorous!

In their "appearance", Sichuan is a paradise on earth - there are no thieves, no high taxes, and it is very easy to be forced into labor!

The most important thing is that everyone can have enough to eat, and there is a tael of silver every month!

Twenty years later, you can still receive a pension!

With such human flesh propaganda, the people of Shanxi, Henan, and Huguang can't be calm!

Some of the thieves who were not surrounded in the carriage gorge are not calm!

I heard that the big ship of Xichang is on the Yangtze River, and those people who want to move to Sichuan are not calm!

Since May, the people have been running to the Yangtze River in twos and threes, and they can't pull it!

By the end of May, a large area of black pressure on the Yangtze River!

All waiting for the boat to sail west!

This way of gathering is no different from that of thieves - hundreds of thousands of people help the old and the young, and there is no way out!

This posture frightened the officials and garrisons of the provinces a lot!

When the news reached Wang Li's ears, he was so happy that he couldn't sleep all night!

Immediately sent more than 100 large ships, loaded with grain, to welcome!

And ask the ships going up along the way to load as much as they can!

As much as possible, move all the people to Sichuan as soon as possible!

In Wang Li's eyes, Sichuan lacks nothing, but it lacks people!

Cheap labor takes the initiative to move, and there is no reason to refuse!

After receiving Wang Li's recital, Zhu Youzhen readily agreed!

After all, most of the people who moved away were the people of the northwest!

The natural disasters in these provinces remain unchanged, and the thieves are rampant!

There is no grain harvest, and hunger is everywhere!

Some people took the initiative to take the hungry people to Sichuan for "temporary resettlement", and naturally they couldn't ask for it!

If they all move away, there will be no one to mess with!

Anyway, that's what Zhu Youzhen thinks!

The most important thing is that the imperial court did not allocate a copper plate!

Standing on the cliff of "Luokung Rock", looking down on the Yangtze River, Wang Li was a little shocked!

One by one, the great ships that transported the people went west!

From morning till night, there is not a single moment of interruption!

This posture almost completely "hollows out" Daming!

"Factory Gong, until yesterday, 1.2 million people have moved into Sichuan, if there are thieves among them......"

Song Zhe's voice trembled a little!

"It's okay!"

Wang Li spit out a puff of smoke rings and smiled nonchalantly: "The biggest thieves are not surrounded in the carriage gorge!"

The rest of the thieves who are petty and troublesome, as long as they have a bite to eat, will immediately become good citizens!

Sichuan has land, and it is no problem to feed 20 million people!

Even if there are thieves who infiltrate Sichuan, they will have no time to rebel except for serving in the conscription or playing mahjong! ”

The corners of Song Zhe's mouth moved, and he didn't persuade again.

However, pointing to the county seat of Wuxian County in the northeast, Song Zhe spoke again: "Factory Gong, why did you deploy the barrage iron cable in the "Xiamatan"?

Wouldn't it be better if we went 12 miles downstream, cut off the Yangtze River at "Konghou Tuo" and "Sheepfold", and use the neighboring Wuxian County as a base? ”

"No!" Wang Li shook his head and smiled confidently: "Wouldn't it be better to leave Wuxian to the enemy to hoard troops and grain?" ”

Song Zhe thought hard for a long time, and gradually understood Wang Li's intentions!

Going down from Wu County, there is only a "Badong" city 95 miles away!

On both sides of the Yangtze River in this section, the mountains and rocks are steep, the land route is difficult to travel, and there is almost no place to hoard troops!

With such a terrain, not only the enemy cannot amass troops, but also himself!

If you want to deploy the barrage iron cable and the city fort, you need countless gunpowder to open the mountain and split the rocks, and the amount of work is too large!

If it is more than ten miles upstream of Wu County, the terrain is very different!

The terrain on both sides of the river is flat, and it is much easier to build fortifications against the mountains!

After the people moved to Fengjie, the original city wall has been blown up, and the terrain is flattened!

You can hoard troops and food, but there is no danger to defend, and it is easy to be attacked by incoming ships!

This is clearly digging a hole for the enemy!

"Are the boats that are about to sail over the people who have moved from Henan?"

Song Zhe raised his binoculars, saw the flag on the bow of the ship, and nodded.

"Exactly! From among the people from Henan and Shanxi, 3,000 strong people were selected to go to the "General Beach" and "Xiama Beach";

At the same time, withdraw the original 3,000 conscripts! ”

"Factory, aren't there 3,000 conscripts in the construction of fortifications in these two places? Why replace? ”

"Oh, the people of Sichuan are not as good as the people of Henan!

For example, height, the average Sichuan nationality is half a head shorter!

Use the people of Henan or Shanxi to build city fortifications, and you will be able to get twice the result with half the effort! ”

Wang Li's fallacy, Song Zhe always felt that something was wrong, but he couldn't refute it.

Raising the binoculars, I searched for a long time among the countless incoming ships, and suddenly became excited!

"Factory man, it's here, it's here!

Shanxi's iron casting craftsmen have finally arrived! ”

Hearing this, Wang Li hurriedly raised the binoculars.

Seeing the flag of the incoming ship, his face was overjoyed, and he stumbled down the cliff.

Wang Li already has plans to recall Cao Wenzhao, but he has to wait until after Huang Taiji withdraws his troops!

Before this, the cast iron craftsmen from Shanxi were first called back!

Along with the craftsmen, there is also a whole shipload of "steam engine" and "generator" parts!

Wang Li came to "Luokung Rock", not only to inspect the construction of fortifications along the river, but also to wait for the arrival of craftsmen!

Because, Shanxi's cast iron craftsmen have better technology than Sichuan!

Before this, Wang Li had already tried!

I wanted to cast a few bearings, and temporarily recruited a group of Sichuan craftsmen.

However, with their skills, they can't even make iron balls!

……

Fengjie County, which is dozens of miles upstream of Wushan, was also called "White Emperor City" or "Yong'an" in the Three Kingdoms era.

Here, an iron casting workshop has been built for a long time, and thousands of catties of iron ingots have been prepared!

As soon as the craftsman arrives, he will be able to start work immediately!

The craftsmen from Shanxi are really different!

The "steam boiler" and "steam delivery pipe" that were unloaded on the ship were actually connected by screws!

Put on the "washer" made of cowhide, the air tightness is very good!

The "cylinders" and "pistons" that I am most worried about are polished very smooth!

The "air intake" and "exhaust port" on the top of the cylinder are round and round!

These parts, from the naked eye, are basically flawless!

The assembly is complete, and the water is boiled for aeration.

Fail!

Predictable!

Between the cold and the cylinder, between the iron column and the cylinder block of the exhaust port and the air intake, all are leaking!

The gap between the piston and the cylinder looks like it's only the size of a hair!

The craftsmen have polished it very meticulously, which is already the limit of craftsmanship in this era!

But, it's just going to leak!

So, here's the problem!

What is the way in which the steam engine, which was improved by Watt, is sealed between the cold and the cylinder?

Put a ring rubber ring on the piston, which should ensure air tightness and will not hinder the reciprocating movement!

However, when the steam engine was widely used in Europe, rubber had not yet been discovered!

Woowoo......

The one next door, on the second day after crossing the Qin Dynasty, made planes and tanks!

That's a cow!

Why can't I?

Is it because I'm a scumbag?

However, in junior high school physics, I'm not a scumbag!

"Factory father, Zhu Kezhen has arrived!

With him, there is also a little girl! ”

Little girl! Ou also!

My little princess of Changping, it's time for you!

I wanted to foster you in Tianyin Pavilion, but then I thought about it, it was really inappropriate!

The dignified princess of Daming, if she grew up in a brothel, if Zhu Youzhen knew about it, she would definitely not recognize you!

Sichuan's economic environment may not be as good as Jiangnan!

However, there are green mountains and green waters!

Moreover, the humidity in Sichuan is heavy, and there is no wind and sand in Beijing, which is particularly good for the skin of the female baby!

Living here for a few years will definitely raise you to be smart!

I wanted to hug the cute little princess, but I thought about it or forget it!

When she grows up, let's hug her slowly!

At this point, a few glances from a distance are enough!

"It's been months, and you haven't cried anymore, have you?"

"Nope!"

Zhu Kezhen waved her hand to the boat, and then said with a smile: "With Humble Jing with her, and a little girl of the same age to accompany her, she has long been used to it!" ”

"By the way, is there a ...... How to recognize Queen Zhou? ”

"Don't worry, I have made an appointment with Queen Zhou for seven years, and I have her hairpin as a token, she will not forget!

Moreover, when Humble Jing bathed her, she noticed that there was a red plum blossom-shaped birthmark on her right arm, and Queen Zhou would definitely recognize her! ”

"That's good!"

Wang Li was relieved and said solemnly: "I built a mansion at the foot of Qingcheng Mountain, which is secretly protected by Jinyi Wei, which is very safe!"

Your family, stay there for the time being! ”

"No need! Just take the child to live! I...... Is it to return to Beijing, or to Fujian? ”

"There are Chen Wangting, Yuan Chonghuan, Cao Dingjiao, Cao Bianjiao and Song Yi in Fujian, which is enough!

After a few days of rest, it's better for you to return to Jingshi! ”

"It's according to the factory's will!" Zhu Kezhen nodded in agreement, and suddenly leaned into Wang Li's ear: "Factory Gong, have you noticed the "Restoration Society" that has risen in the south?" ”

Resumption of Society!

What Fusha?

Could it be that it is the second Donglin Party?

Alas, whatever!

There is Wei Zhongxian in the south!

There is no room for a grain of sand in his eyes!

All the cows, ghosts, snakes, and gods are just floating clouds!

Don't worry about me!
