As long as you can conquer Yecheng and defeat King Sima Yong of Hejian, half of the North China Plain will fall into Sima Ji's hands. But this is quite difficult. Yecheng was once the capital of Cao Wei, but it was a city that was mainly managed.

During the Cao Wei period, the population was more than 400,000, which was similar to that of Luoyang, the capital of the Jin Dynasty. Although it is only one of the five capitals, there are still nearly 300,000 people. Compared with the Jicheng that Sima Ji expanded several times, it is not a pity.

There are five military camps in Yecheng City, covering a large area, and the famous Tongquetai is also among them. There is no shortage of places to station troops. Moreover, the Tongquetai is only one of the three platforms in Yecheng. All three platforms are in the Tongque Garden, Tongquetai, Golden Tigertai, and Ice Well Platform. The three platforms are connected by a retractable floating bridge pavilion. They store a large amount of wartime supplies.

Judging from the status and importance of Yecheng and Jicheng, it is expected that Hejian King Sima Yong would give up Yecheng and take the initiative to attack Sima Ji. This kind of good thing Sima Ji could only sleep now and think about it in his dream. If nothing unexpected happens, Sima Ji must have led his army south to challenge Hejian King Sima Yong who guards Yecheng under the iron wall of this capital of Cao Wei.

"No wonder the Sui Dynasty wanted to burn Yecheng, to avoid another major trouble in Shandong." Sima Ji couldn't help but sigh that if the world is unified for a long time, the importance of Yecheng will definitely be lower and lower. However, the Jin Dynasty has only been unifying the world for only twenty years until today. Even the last emperor of Wei is alive. How dare you not take Yecheng seriously?

After seeing off the messenger, Sima Ji summoned the Jizhou commander of Jinwei and said straight to the point, "I want all the news about Yecheng, how high the city wall is, how many city gates, how many people are, how many soldiers are in the five barracks, how many arms and food are in the three platforms, and it is best to say hello to the people of Yecheng."

"The little man will arrange the manpower immediately, but the little man has lived in Yecheng for a while. The drinking water in Yecheng comes from Zhangshui, and the ditch of drinking water is under the Tongquetai. As for the remaining news, please give the little man two months to find out." The commander of Jizhou clasped his fists and led his troops. After saying something, he left the royal palace.

Tongquetai? Sima Ji was stunned and shook his head. For a giant city like Yecheng that is located beside many water systems, water siege is useless. Drinking water floods Yecheng may work, but Sima Ji cannot choose this method unless it is absolutely necessary. King Yan is an ordinary person, how can he compare with Bai Qi to replicate the achievements of Bai Qi flooding Chudu.

If you want to go south in Youzhou, you must compete with the King of Hejian's Yecheng, and the King of Yan has no choice but to prepare to have a head-on battle with Sima Yong at the time of Yecheng.

Head-on battle requires an army. Even if Sima Ji scrapped the land of Youping and the other states, it would not be comparable to Sima Yong in terms of quantity. He now has a 100,000 army, but there is still no recruitment. It would be great that he could raise 100,000 yuan after recruiting.

But Youzhou has an advantage that Jizhou does not have, that is, north of Youzhou, there are a group of Hu people with stronger mobilization than the Central Plains. After all, they are hundreds of thousands of people who control strings. The Hu people's mobilization ratio is definitely stronger than that of the Central Plains that need to farm and maintain logistics. For the people of Youzhou, you can draw one in five or one, which is already a very high proportion, but this proportion can be said to be ordinary for Hu people.

Although the land is vast and sparsely populated, the area is fortunately large enough. It is at least ten times the area of ​​Jizhou. Even if the land is vast and sparsely populated, so much area can easily exceed the population of Jizhou as long as it taps its potential.

"Your Highness, don't be sad." Yang Xin, who came to visit Sima Ji with the baby, carefully comforted him when she saw Sima Ji's appearance, "Look at Ji'er, I'm very well-behaved recently."

"You don't need to look like this. It has nothing to do with you when I am in a bad mood." Sima Ji shook his head slightly. Since he found an excuse to take Yang Xin a slap in the last time, Yang Xin has obviously become much more cautious.

Recently, he discovered that every time Yang Xin came to visit him, he always held his son. Is this considered reminding him that there are hostages? Seeing that Sima Ji was not interested, Yang Xin asked, "Is Your Highness sad for the prince's affairs?"

"That's right!" He sighed inwardly, and Sima Jihan said vaguely, "The emperor has only this son. What's wrong with it? The consequences are unimaginable. Xin'er, you have to be prepared, and the world may not be calm."

"Xin'er understands that no matter what happens, Xin'er will stand with her husband." Yang Xin is a very smart woman. Sima Ji is very abnormal recently, and she also feels that her husband may be making some preparations.

In the domestic city thousands of miles away, this original capital of Goguryeo was used again after several years of desolation and gradually recovered its vitality. It also welcomed a new owner as a base for continuing to go north to use and was renovated.

Of course, this is also inseparable from the foundation laid by the former owner. In the end, because of the location and the cost of building a new city, it became a city run by the Youzhou Purchasing Department. Of course, in principle, it still belongs to the jurisdiction of the Dongyi School Mansion.

"Your Highness asked you and me to count your household registration in the Jurchen land? Is this the intention of taking the Jurchen land for yourself? But then again, we have been here for so long, aren't we just waiting for this news?" Li Shan said excitedly as he pinched Sima Ji's letter, "Is this going to open up the territory? Last year I went to the Jurchen land, which is really a good place. Last time, His Highness wrote a letter and asked why the land north of Goguryeo is black?"

Zhang Daze pinched his chin and turned a deaf ear to Li Shan's nagging, all thinking that mosquitoes were harassing him. After a long time, he said, "It's not that simple. Why would you wait until now if you want to open up your territory? If you set up New South Wales like the Southern Expedition, the land of Goguryeo would be enough, but Your Highness did not do this and gave up such great achievements."

He took the letter from Li Shan's hand and looked carefully. Zhang Da looked at the last word on each line. The four words from left to right were Wu Ding one, and he also used the simplest words. When he saw Zhang Da jumping up from the chair, he remembered that when King Yan was very young, he wrote from left to right when he wrote, and it took a lot of time to correct it. At the beginning, he liked to use very simple words to write, which Li Shan was a latecomer who didn't know at all.
