After returning to the Hanzhong Marquis Mansion and resting for two days, Lin Chuan began to write to Cao Cao, suggesting that Xianbei be completely subdued.

Because he knew about the history of Wuhu Chaohua, Lin Chuan had always been very careful about the Xianbei people, and Lin Chuan also told Cao Cao the history of Wuhu Chaohua when he was on a desert island.

Now Youzhou's troops are the first of the states of Great Wei, in order to prevent the Xianbei people from rebelling.

Fortunately, after Lin Chuan began to build Hanzhong branches and production bases in the states of Dawei, Dawei and Xianbei opened a mutual market.

Relying on the mutual market, Dawei sent a large number of daily necessities to Xianbei, and Xianbei also sold a large number of war horses to Dawei.

Xianbei, who had obtained enough living materials, naturally slowed down the pace of aggression against Great Wei, of which the root of Budu is the best example.

There is also the fact that the Xianbei people sold a large number of war horses to the Great Wei in a short period of time, which further expanded the scale of the Youzhou Iron Cavalry, which was also the main factor that caused the Xianbei people to dare not easily invade the Great Wei.

After years of recuperation, the Xianbei people have also begun to gradually recover, and if they continue to drag on, they may become a threat to the northern part of the Great Wei in the future.

Now that the Great Wei is about to start maritime trade, and may also use troops overseas in the future, then Xianbei, a time bomb in the north, cannot adjust its detonation time backwards, but must completely solve this hidden danger.

This time, when Lin Chuan sent a letter to Cao Cao again, he emphasized the advantages and huge benefits of the Great Wei's future maritime trade.

In order to obtain huge profits from maritime trade, it is necessary to ensure that all production bases in the Great Wei can carry out normal commodity production, and Youzhou, which has more than 300 production bases, cannot affect the output of Youzhou production base because of the threat of Xianbei people.

After explaining the importance of the internal stability of the Great Wei, Lin Chuan once again explained to Cao Cao the importance of solving the threat of the Xianbei people in terms of the use of troops abroad.

In the future, if the Great Wei wanted to firmly control the maritime supremacy, it would have to garrison the islands along the coast of the Great Wei and build shipyards and cities as supply points.

Lin Chuan gave Cao Cao a clear description of the benefits of subduing Xianbei as soon as possible and the impact of Xianbei's rebellion on the future development of Great Wei.

After sending the written letter to Cao Cao, Lin Chuan waited in Han for the action of Yecheng's side.

Yecheng, the palace of the king of Wei.

The breath of the Spring Festival has not completely disappeared from the palace of the king of Wei, and Cao Cao is enjoying the snow scene in the palace of the king of Wei with Cao Pi and Cao Zhi.

"Father, Lord Wang, now that Great Wei has captured Goguryeo and solved the trouble of Shanyue, God bless Great Wei.

And this year's snowfall is also just right, so you can meet next year, and it will be a good year! ”

Cao Pi said to Cao Cao with a smile, and wondered if he could take this opportunity to ask Cao Cao to transfer Sima Yi back to Yecheng.

Cao Cao was also happy when he heard this, and said to Cao Pi and Cao Zhi: "Yes, next year will indeed be a good year!" ”

"My father loves the people like a son, and the Great Wei officials rule Qingming, so they will naturally be protected by God."

Cao Zhi also said with a smile on the side.

After Yang Xiu sent an envoy to Xianbei, Cao Cao promoted him to the position of Dahonglu in charge of diplomacy, which seemed to be Yang Xiu's promotion, but in fact, Yang Xiu was arranged outside the power center of the Great Wei.

This time, Cao Pi and Cao Zhi came to the Wei Palace, just to rescue their teacher and persuade Cao Cao to transfer Sima Yi back to Yecheng and Yang Xiu back to Cao Zhi.

Cao Cao didn't understand the thoughts of his two sons, but it was impossible for him to give Sima Yi and Yang Xiu a chance.

Now Cao Chong's performance is obviously better than Cao Pi and Cao Zhi, and Cao Chong and Lin Chuan have the closest relationship.

Cao Cao is now over sixty years old, but his body is still very tough, it is not a problem to live to be more than eighty, and he can control Great Wei for at least ten years.

Cao Pi and Cao Zhi, who are over 30 years old, are no longer Cao Cao's ideal successor candidates, so weakening the power of the two and ensuring the concentration of power in the Great Wei has always been something that Cao Cao is trying to accomplish.

Now the Hanzhong Chamber of Commerce and the production base cannot replace the scholars in various states and counties, and the economic system of the Great Wei is mainly controlled by the scholars, but Cao Cao has mastered a financial channel that is not restricted by the scholars through the Hanzhong Chamber of Commerce.

Then Cao Cao, Cao Pi and Cao Zhi kept talking about the development of the Great Wei and the people's livelihood, so that neither Cao Pi nor Cao Zhi had the opportunity to put forward their own demands.

At the same time that Cao Cao, Cao Pi and Cao Zhi staged the filial piety of father and son together, Lin Chuan's letter was also delivered to the palace of the King of Wei.

After Cao Cao received the letter, he said to Cao Pi and Cao Zhi: "Your father has realized your intentions, and today your father is tired, so go back too!" ”

"Yes, the retainers are retired!"

Cao Pi and Cao Zhi had no choice but to leave the Wei Palace and return to their respective mansions.

Cao Cao took Lin Chuan's letter and came to the side hall of the palace, and after opening it, he checked it carefully.

After a long time, Cao Cao's hearty laughter came from the side hall.

"Hahaha, Mr. Lin's suggestion is really timely!"

Early the next morning, Cao Cao called Cheng Yu, who had not yet returned to Youzhou, as well as Jia Xu and Xun Yu, to the palace of King Wei.

After the three of them came to the palace of King Wei, Cao Cao read Lin Chuan's letter to the three of them one by one.

After Cheng Yu, Xun Yu, and Jia Xu had all read Lin Chuan's letter, Cao Cao began to ask Cheng Yu, who had been sitting in Youzhou, if it was feasible to start the plan to subdue Xianbei now.

"Zhongde, in your opinion, can the subjugation of Xianbei that Mr. Lin said be completed within this year?"

Cheng Yu pondered for a moment when he heard this, and then replied to Cao Cao: "Lord Wei, what Mr. Lin said about the Xianbei trouble, the old minister feels that after conquering Goguryeo, the Xianbei people have indeed reined in.

Before, the old man thought that Zhao Chi, the general of Goguryeo, had his cavalry pretend to be Xianbei people and come to Liaodong County in Youzhou to rob the people for some finances, and there would be anything strange about this matter.

It wasn't until the old minister captured Goguryeo that he learned from the personal soldiers under Zhao Chi that it was the Xianbei merchant who used heavy money to bewitch Zhao Chi, so Zhao Chi did such a stupid thing.

Now that I think about it, I'm afraid that it is the Xianbei Kebi Nengbu who still covets the land of Youzhou in his heart, so he will secretly provoke the dispute between the Great Wei and Goguryeo, so that he can fish in troubled waters! ”

After Cheng Yu finished speaking, Cao Cao became more concerned about completely subduing Xianbei as soon as possible.

"The old minister sees that Xianbei is lifting a stone and hitting his own feet, Goguryeo has now become the county of Great Wei, and the Xianbei people can't escape the palm of Great Wei this time!"

Xun Yu felt that it was not a big problem for Dawei to subdue Xianbei, and with Dawei's current national strength to deal with Xianbei, it can be said that Xianbei had no power to fight back at all.

"Lord Wei, if you want to subdue Xianbei without sword soldiers, you need to think about it seriously."

Jia Xu also said on the side.

Although everyone has no objection to subduing Xianbei, the Xianbei people are different from the Shanyue people, and if the Great Wei uses a large army to enter the grassland, it will require too many troops.

Next, how to subdue Xianbei at the lowest cost has become a problem discussed by Cao Cao, Cheng Yu, Xun Yu and Jia Xu.
