Listening to Sima Fang's suggestion, Cao Cao resolutely raised troops to prepare to attack Xuzhou, he played the banner of revenge, recruited some soldiers and horses from Yuzhou and Yanzhou, with Xiahoudun and Xun Yu as the guard, Xiahou Yuan as the vanguard, supplemented by Cao Ren and Sima Fang, and personally led an army of 50,000 to conquer Xuzhou.

Before attacking Xuzhou, Cao Cao, in order to curry favor with Yunzhou, lifted the ban on alcohol in the Central Plains, released Yunzhou's wine into Yanzhou and Yuzhou, and crowned Guo Jia's son Guo Ye as the Marquis of Guannei in the name of the Son of Heaven.

The news soon spread to Jizhou.

"It seems that Cao Cao is really going to fight Xuzhou this time!"

Putting down the scroll in his hand, Guo Jia said with a smile.

Skynet's clean and neat job successfully triggered the most famous Yanxu battle in the world.

Lord!

Cheng Yu suggested: "Cao Cao attacked Xuzhou, the south bank of the Yellow River must be empty, it is better to order a partial division to smuggle across the Yellow River, go straight to Xudu, and a battle can be decided!" ”

Hehe!

Guo Jia smiled slightly, he didn't want to fight Xu Du now, even if he beat it, he couldn't hold it. Because Yunzhou's economic upgrading has not yet been completed, the financial resources that can support it are limited.

After all, Guo Jia's foundation is in the north, and after laying the foundation, Xu must allocate troops to protect it, and it is not convenient to cross the Yellow River after all.

Besides, those fragmentary princes, Guo Jia didn't bother to clean them up one by one, so it was better to let Cao Cao clean them up.

What we need to do now is to protect Yunzhou's economy and successfully complete the upgrade, so that we can have a steady stream of financial resources to support Guo Jia's great cause.

"I'm not busy with this, Zhongde, you've been in the Bohai Sea for some days, tell me, what is the development potential of the coast?"

Guo Jia diverted the topic and asked.

This......

Cheng Yu didn't expect Guo Jia to suddenly ask this question.

After hesitating for a long time, he said: "Bohai Sea is located on the border of Jizhou, east of the sea, the land is barren, and if you farm, you can barely fill your stomach." If it weren't for the surrounding sea, I am afraid that the people would not be able to live for a long time if they could go out to sea to fish to supplement their families. ”

Although Jizhou is fertile for thousands of miles and has a large population, the land suitable for cultivation is concentrated in the central and western regions, and the coastal land of Bohai is still somewhat barren.

Not bad!

Hearing Cheng Yu's analysis, Guo Jia also nodded, still agreeing with his point of view.

The Yellow River has been diverted many times in history, and the estuary of the Han Dynasty was in this Bohai County.

Therefore, the water system in Bohai County is developed and there are many rivers.

For others, these rivers are hidden dangers, but for Guo Jia, a traverser, this is paradise.

In this era, there was no north-south Grand Canal, and there was no large-scale water transportation, and most of the transportation of materials was land transportation, which consumed a long time and consumed a relatively large amount of time, and the transportation efficiency was relatively low.

If we could switch to water transportation, we would be able to save most of our energy.

Guo Jia is interested in building a water transport network and adopting the method of parallel sea and canal transportation to solve this problem.

The rivers all over Jizhou have become Guo Jia's preferred place.

He had to first connect the waters of the northern territory.

There are two main water systems in the north, one is the Yellow River and the other is the Haihe River.

The Haihe River is a little better, the water system is relatively stable, which is conducive to the construction of canals. But the Yellow River is a little difficult, the downstream is okay, the higher it goes, the more difficult it is to control.

Guo Jia does not have the courage of Emperor Yang of the Sui Dynasty to open up the five major water systems of the Central Plains and establish a grand canal connecting the north and south.

He just wanted to connect the water system of Jizhou first, and then open the outlet by sea, and then digest it by water.

In this way, the resources needed for the development of the north can be transported in a steady stream.

"Build a canal?"

Hearing Guo Jia's words, Cheng Yu couldn't help but be a little dumbfounded.

It's not a one-day or two-day project.

"I just want to connect the Haihe River with the Yellow River first."

Guo Jia said lightly.

Cheng Yu was stunned for a while, then hugged his fists and said: "Lord, this is a move to work hard and hurt money, and you can't do it." ”

Although he can be regarded as a person with excellent intelligence, he can't understand Guo Jia's hard work.

Guo Jia took out a picture and said, "This is the Yellow River, this is the Haihe River!" These are the two largest water systems in the north, and if these two water systems can be connected, the whole north will be our waterway channel. I plan to build a maritime yamen in the Bohai Sea and build the largest deep-water port in the north. With shipping as the leader and water transportation as the hub, it has become the center of the world's sea routes. ”

He glanced at Cheng Yu meaningfully: "When the time comes, Bohai will be the leader." ”

In order to change the dilemma of nomadism in the north and the border trade in Yunzhou was also facing no business to do, Guo Jia set out to transform Yunzhou's economy into an export-oriented export economy.

In order to expand Yunzhou's exports, Guo Jia was interested in replacing land transportation with water transportation.

Although sea freight is risky and slow, it has a large carrying capacity and can transport a lot at one time.

And Yunzhou's naval power is proud of the surrounding areas, as long as there is a naval force, it can protect its own business routes.

"Lord, the grand plan is big, and the subordinates admire it!"

Cheng Yu said sincerely.

He was really impressed by Guo Jia's idea.

"I'll leave this matter to you, and you have to ask someone to investigate the surrounding area to see if there is a suitable place to dig a canal. Take a rough estimate of how much manpower and time you need. ”

Guo Jia admonished.

This matter is not busy for a while, and it will take a few years to complete the planning now.

Got it!

Cheng Yu nodded.

This is a big project, and if it is done well, it will definitely be something that will go down through the ages, so naturally it cannot be taken lightly.

"Lord!"

Dian Wei hurriedly came to Guo Jia's face.

"The news just came that Ma Chao launched a coup d'état, killed Han Sui and Ma Teng, and monopolized the power of the soldiers and horses in Liangzhou and Yongzhou. Ma Chao has already said that Tongqiang people, leaving the customs has become a foregone conclusion. ”

Cai Yu left, and the responsibility of Skynet was handed over to Dian Wei.

What the?

Hearing this, Guo Jia was slightly stunned.

Ma Chao has the sole power, which is really a bit of a surprise.

It was not surprising for Guo Jia that this guy killed his own Lao Tzu, because he was a cold-hearted person.

But Han Sui was also killed by him, which surprised Guo Jia.

Han Sui of later generations dominated Xiliang for decades and became a veritable king of Xiliang.

Unexpectedly, he was killed by Ma Chao.

It seems that his appearance has changed the direction of many history.

"Order and assassinate Shi Wu Yi and Zhenxi generals Zhang Xiu and Xu Huang, let them hold the party, and don't provoke them for the time being."

After Ma crossed the pass, the first person to bear the burden was Si Li, but the current Si Li was empty. I don't know if he wants to go north to fight and merge states, or go east along the river to fight Cao Cao?

However, Guo Jia's estimate is that Ma Chao went to fight Cao Cao more. After all, when it comes to the degree of wealth, there is no comparison between Bingzhou and Yuzhou.

Guo Jia couldn't help but squint his eyes, looking forward to what happened next.
