After Xin Bi sought Guan Yu for help in Xiapi to no avail, he could only continue to go all the way south.

Fortunately, Yuan Tan is not a fragile item that can be hung at the touch of a button, and after he was granted the administrative and military power of Bohai County by Yuan Shao, he could still resist Cao Cao for a few months.

Cao Cao originally needed to completely clear Hejian County first, so that the northern end of his territory would reach Yishui on the border of Jiyou, and it was estimated that it would be almost the end of August after all this.

When Cao Cao attacked the Bohai Sea further east, if Yuan Tan chose to fight for every inch of land, he would be able to carry it for at least two or three months.

If Yuan Tan forbears for the time being, and chooses to throw the unsafe place between the countryside to Cao Cao to grab a handful, and only rely on Nanpi Jiancheng to defend it, then it can be delayed for a longer time, at least until next year.

So there is still time for Simbi.

After leaving Xiapi on the ninth day of the seventh month, Xin Bi spent more than a day passing through Xiaxiang and Lingxian to Huaiyin, which was not unpleasant.

Originally, he wanted to work tirelessly to continue to change horses and gallop, but Chen Qun, who was guarding Huaiyin, told him that he would go south by land, passing through the surroundings of Sheyangze, and the horses would have to make a detour because of the mud and difficulty, and it would be faster to take a boat to the Hangou Canal.

Xin Bi was indeed too tired to do it, and his physical strength was at the limit. He pushed the boat down the river and listened to Chen Qun's persuasion, and switched to a canal boat, but spent money to hire more sailors to support the oars and strive to make the boat go faster.

Before the Xinbi family followed Yuan Shao, they were all from Yingchuan County, Yuzhou, so they knew the south better than those Hebei strategists.

Although he had never been to Jiangdong, Huaisi had been there, and he knew what kind of bird the Hangou Canal was in his early years.

After getting on the boat from Huaiyin, he soon found that the situation was very different from his impression.

When he came to Huaisi, Guangling County was still under the rule of Zhang Chao and Zhao Yu.

Zhang Chao had no intention of governing the place at all, as soon as he sat in the position of Guangling Taishou, he thought about plotting with his brother Zhang Miao and his subordinate Zang Hong to discuss Dong.

Although it cannot be denied their enthusiasm and merit in courting Dong, in terms of the local people's livelihood, Guangling County was not lightly mobilized at that time.

Later, although Zhao Yu, who was sent by Tao Qian, restored his livelihood slightly, he was immediately destroyed by Zhenrong. Therefore, in the impression of Simbi, the Hangou Canal is a stinky ditch in disrepair, and many places are still shallow and difficult to walk, and there are often "blocked boats" to queue up to pass.

Unexpectedly, he hadn't been to the south for a few years, but now the ditch he saw has been treated, and the shallow places have been dredged thoroughly.

In some places prone to river collapse, especially near the port wharf, the river edge was even reinforced with stone and wooden piles.

After only a day and a half of sailing, Xin Bi arrived at Guangling from Huaiyin via Sheyangze, and he thought that if he rode a horse and took a straight road, he might be able to sail faster. But if you want to ride a horse to bypass Sheyang Daze, it should actually be slower.

"The governance of the lord in Hebei is also regarded as resting with the people, and Jizhou is known as the valley branch for ten years. But compared with Guangling under Liu Bei's rule, I am afraid it is still too far behind.

I heard that when Liu Bei was in a desperate situation, he met Zhuge Jin here who was hiding from the war. From this point of view, Zhuge Jin not only has unfathomable strategies, but also cannot be underestimated even his talent for governing the country. ”

Simbi couldn't help but think like this in his heart.

And when he sailed out of Guangling and into the Yangtze River, that sense of unreality finally reached its climax – at least so far.

"Why are you lazy and don't hold on? This trip to Moling is urgent! ”

Before entering the Yangtze River, the sailors who were holding the penny and rocking the oars stopped. Xin Bi was in a hurry and couldn't help but scold anxiously.

But the sailors told him as a matter of course: "The last twenty miles are densely packed with ships, and everyone is going downstream, and it is easy to hit the ship in front of them if they rush to hold the fence." ”

Simbi walked to the deck and looked back and forth, only to realize that it was indeed the case. A large number of boats lined up slowly, blocking the canal, and all the boats were not rocking the fence.

This scene really shocked Simbi: there are still automatic ships in the world?

The fleet waved for a while, and finally stopped waiting, and Simbi was anxious again, but was told that he would wait for the Yangtze River to recede and the water level was low enough to open the gate and enter the Yangtze River. Simbi could only wait, and his heart was full of curiosity.

Finally, he was lucky, when he arrived at the mouth of the river, it was past the highest point of the tide in the afternoon, and after only an hour, the canal gate was opened, and a hundred boats rushed into the Yangtze River.

Xin Bi couldn't help but be solemn, and asked the boatman in charge: "Who built this lock?" I read ancient books, only to know that since ancient times, Qin Shi Huang has built a spiritual canal to connect Xianggui, and once built a sluice, but compared with this, it is also very different. It is unbelievable that this lock can accurately use the high and low tides to make the ship windless and automatic, relying entirely on the current. ”

The boatman in charge of this ship couldn't help but smile proudly: "Mr. is a northerner, I don't know this, of course this lock was built by Zhuge Fujun." ”

Xin Bi: "Zhuge Jin? ”

Boatman: "Then you really guessed wrong, Guangling is the masterpiece of Mr. Kong Ming - but the two brothers of Zhuge Mansion have the ability to penetrate the heavens and the earth, so everyone should be able to do it, this little thing will not be difficult for them."

The Jiangnan Canal on the other side has also been rectified and renovated by Mr. Ziyu in the past few months. ”

While the two were chatting, the canal boat sailed into the Yangtze River, turned upstream and sailed dozens of miles. Xin Bi didn't care at first, because Moling was already further upstream of Guangling, and he had to go upstream.

However, after driving for dozens of miles, the boat crossed the Yangtze River diagonally, docked west of Dantu County on the south bank, bypassed Jinshanzhou, and sailed into the Jiangnan Canal.

The Jiangnan Canal, like Hangou, was built in the Spring and Autumn Period, and was later repaired and connected by Emperor Yang Guang of the Sui Dynasty in history, and became part of the Grand Canal.

It's just that the ditch was first built by Wu Wangfucha, and the Jiangnan River was built by Goujian, the king of Yue.

Xin Bi couldn't help but wonder when he saw that the boatman had sailed the boat into the Jiangnan River, instead of going directly against the Yangtze River to Moling:

"Since you want to take the Jiangnan River, why don't you just cross the river and sail due south when you are in Guangling? Do you want to swim against the Yangtze River for dozens of miles? The Jiangnan River is at the mouth of Dantu, isn't it just opposite to the mouth of the Hangou River in Guangling? ”

The boatman once again proudly displayed: "That was all before!" Now the whole territory of Danyang is under the rule of Zhuge Fujun, and since March, he has taken advantage of the summer slack to levy and issue forced labor, and renovate the northern mouth of the Jiangnan Canal!

Nowadays, the Jiangnan Canal connects the Yangtze River, and it is also a bifurcated river between the south and the north, without interfering with each other, and you don't need to brace the penny and operate the sails, just rely on the water flow to go down! The water level of the Yangtze River at the mouth of the river upstream is high, giving boats to the south. The water level of the Jiangnan River in the old estuary downstream is high, giving boats to the north. ”

Xin Bi had the mental preparation of Guangling, so he was not so surprised this time.

The Zhuge brothers really have the ability to execute, and it should only be more than four months for Danyang County to fully restore order. This time can mobilize the people's power to complete such a remediation project, which has not obviously harmed the people's livelihood, and the planning and management are absolutely first-class in the world.

Of course, this amount of work is not as large as Xin Bi expected, because the canal itself is original, as long as it is slightly renovated, dig a fork in the position of connecting the Yangtze River for dozens of miles, and then build two gates.

Xinbi does not understand technology, so he will naturally overestimate the amount of work required to repair the gate. For Zhuge Jin, it is a familiar road.

Especially before Zhuge Jin started, Chen Qun and Jiang Ji were seconded to assist in management, these people had already done a job with Zhuge Liang in Guangling with the same principle, and they knew what common pitfalls there were in this kind of project.

After sailing dozens of miles against the current, Xin Bi and his entourage arrived at Jurong County along the canal, where he landed and prepared to change horses and go to Moling by land.

Fortunately, as Yuan Tan's envoy, Xin Bi's whereabouts are very eye-catching, after Jurong went ashore, he was received by the local county order, Xin Bi mentioned that he was going to visit Zhuge Jin when chatting, and the sentence Rong county order told him:

"If Mr. wants to meet Zhuge Envoy, but he doesn't have to go to Moling to fight in the air, General Fubo is still out on patrol in Qiantang recently, Mr. can continue to go south along the Jiangnan River, faster than riding a horse, no need to bypass Taihu Lake."

Zhuge Jin's current local official position is still "Danyang Taishou", but Liu Bei has asked him to "lead the affairs of Yangzhou Pastoral Mansion", so local officials in Yangzhou can also change their voices and call him the king.

Xin Bi couldn't help but wonder: "Zhuge envoy Jun is in Qiantang? I heard that the general of the Che Cavalry entrusted everything with Yangzhou, why didn't he sit in Moling? ”

Jurong County Ling had a natural expression and tone: "Naturally, it is for the control of water, since the pacification of the south of the Yangtze River, in the past half a year, Zhuge has made Jun Yan exhausted, renovated the river, smoothed water transportation, and increased polders.

Jiangnan and Hebei start from Dantu, south to Qiantang, I heard that Qiantang side, there are also the same as Dantu here to renovate the estuary, but also lead Zhejiang water to control Yanze, such as Guangling to control the harm of Sheyangze saline-alkali land.

If it can be done, it will be done in one fell swoop, dredging the canal, improving navigation, increasing polders, and lightening the salt along the canal, which is conducive to irrigation for the people. Since ancient times, I have never heard of such a good water control.

Zhuge envoy Jun can come to Wuhui, it is really the blessing of Jiangdong's fathers and elders, from Guangling, Zhi to Danyang, and then to Wu County, all the way south, not falling behind at all. ”

Xin Bi could hear that these words were not a slap in the shoulder, but from the bottom of the other party's heart, because many arguments would not be mentioned at all if they were not personally experienced.

Xinbi sighed, then returned to the ship and continued south.

The fleet passed through Piling from Jurong, entered Taihu Lake, crossed the lake, and entered the southern section of Jiangnan from Wucheng again, and traveled for two more days before finally arriving at Qiantang.

Xin Bi had never been to this place before, so he didn't know how desolate it was and how serious the problem of salt and alkali land was.

But as far as he can see with his own eyes so far, he can also see that Zhuge Jin is serious about controlling water.

When Xinbi's fleet sailed along the old river left by King Goujian of Yue to the area around the Wulinmen Wharf in the north of Hangzhou, they saw a river branch and detoured along the low-lying land at the southern foot of Baobao Mountain into Yanze in the west of the city.

To the south of Yanze, there is a newly dug river, north of Wushan Mountain in the south of the city, picking a low-lying place all the way to the east. Finally, near the Sanbao lock in Hangzhou, it flowed together with the original main river channel and flowed into Zhejiang.

The old canal left by Goujian, the king of Yue, is not connected to Zhejiang, but only near the Gongchen Bridge in Hangzhou in later generations. Because at the time of the Warring States period, there was no ship lock technology.

Although the tide in Zhejiang in the Qin and Han dynasties is not as good as the Guangling tide at the mouth of the Yangtze River, there are still daily rising and falling tides, but they are only gentle, and they will not form a tide. In the era when there were no floodgates, the Jiangnan River and Zhejiang were hastily dug up, and when the tide rose, the seawater would pour in, causing the freshwater system around Qiantang to become salty.

But for Zhuge Jin, he has already tried successfully twice in Guangling and Danyang, and the Zhuge brothers' tidal gates are already very mature enough to ensure that the gates are only opened every day after the tide is low, and these problems do not exist.

Moreover, as early as the Spring and Autumn Period and the Warring States Period, the ancient Yue Kingdom also built a Zhedong Canal in today's Juzhang County and Ningbo in later generations, connecting the Yongjiang Cao'e River and the Zhejiang water system, and the water transportation conditions of the Ningshao Plain have also improved a lot.

It's a pity that the Jiangnan River was not connected to Zhejiang before, so even if the Zhedong Canal is connected to Zhejiang, the inland river ships during it cannot go all the way north. In the middle, you still have to unload and land, change ships at Chantang, and then go down the canal.

After Zhuge Jin's attempt to open up, the Zhedong Canal will be completely connected with the Jiangnan River and Hangou in the future.

In the future, even if the northern section of the Grand Canal is extended to Zhuo County, it will not be called "Beijing-Hangzhou Grand Canal", but should be called "Beijing-Ningbo Grand Canal", because the starting point at the southern end is no longer Hangzhou, Hangzhou is just a relay point, and the southernmost point will be to Ningbo.

Of course, all of this is not yet complete. Even if the canal section is ready-made, Zhuge Jin only needs to open a few nodes, but he also knows how to save people's power and do it a little bit every year, and he will not ask for it to be done so quickly.

Now that Dantu's side has taken advantage of the half a year this year, Qian Tang's side has just started, and maybe he will be able to find time to complete it next year.

Anyway, Liu Bei's camp has time to farm in the south, and Zhuge Jin is not in a hurry at all.

In this life, the Han family is destined to be revived, and there will be no north in the future. Therefore, the spontaneous southern engine of the rulers will certainly be smaller than in the same period of history.

If Zhuge Jin didn't take advantage of Liu Bei's years in the south to speed up the development of the south, so that the rulers of the Han Dynasty realized that the south could accommodate a lot of population and arable land after development, then it would be a little too late when the world was peaceful in the future and the population of the north exploded again.

The South should be developed in advance when the population of the North has not yet broken through the carrying limit, so as to have a buffer period for the spread of migration.

Ensuring the complete unimpeded and integrated connection of the original canal water system has always been the top priority in the development of the south.

Xin Bi didn't know how grand Zhuge Jin's farming plan was, but when he looked at this battle, he knew that Zhuge Jin's handwriting was definitely not small.

Early the morning of the second day after arriving in Qiantang, after being reported, Xin Bi finally met Zhuge Jin, who led the affairs of the Yangzhou Pastoral Mansion, by the salt edge of the west of Qiantang City and the West Lake of the later generations.

Zhuge Jin met him at a water control site.

On the construction site, a canal has stretched from the Jiangnan River, connecting the Yangtze River and Taihu Lake to the West Lake through the canal. Although there is only one connection today, it is not possible to form a convection, and the flow is not large, and it is impossible to quickly desalinate the water of the lake.

But a few years later, with the launch of the supporting facilities, Zhuge Jin was sure that this place could be treated like Sheyangze, and the saline-alkali land could be treated.

Several counties along Zhejiang in the southern part of Wu County will add a lot of high-quality paddy fields.

Zhuge Jin looked at his masterpiece with a sense of accomplishment in his heart, and at the same time pretended to set up a fishing rod in front of him, and then summoned Xin Bi.

"Mr. George, it's hard work from afar, and Master Yuan has asked you to come all the way, I don't know what advice you have?"
