Li Yan died quite decently. After Liu Yi got what he wanted, he did not make things difficult for Li Yan anymore and gave him a happy way to die.

As for why Huang Hao is asked, Liu Yi felt that although Huang Hao was respectful to him, from a historical perspective, this was also a villain, prepared for any eventuality. At critical moments, it might be useful.

"Governor, we have been guarding here?" On the third day after Li Yan was executed, watching Liu Yi start to build various forts around Mengjin, Deng Ai couldn't help asking. According to Liu Yi's current plan, after building the fort, he would be ready to open the wooden tracks to Bingzhou. The battle has not been completed yet. Why do you feel that Liu Yi wants to change his career?

"The fighter plane has been lost!" Liu Yixiao pointed to the map and said without looking back: "We can't advance now. We are here, and the Wei Dynasty or Sima Yi dare not move around, but now there are only 70,000 troops. Do you expect me to attack Yecheng again?"

Sima Yi has persuaded Cao Fang and the ministers of the Wei Dynasty to return to Yecheng, but the impact has begun to appear after the end of the year. At this time, even if there is a strange plan, Liu Yi will not use it. The victory has been mastered. As long as you watch Sima Yi firmly and wait until the war in the Central Plains is completed, the final victory will be achieved.

The most important thing now is stability. I will block Sima Yi here. With Wei Yan joining the battlefield, Cao Shuang is now surrounded by three sides. The successive falls of Xingyang, Chenliu and other places have also made Cao Shuang's current situation quite awkward, and the food supply will not be cut off. After all, there are still large areas of the Central Plains that belong to Cao Wei.

But there is no danger to defend. The Han army is in the attack position. Although Cao Shuang has many troops, it has gradually turned into passive defense. The impact of the Wei court being breached by Liu Yi is here. If Cao Shuang encounters a big defeat, the Han Dynasty will swallow the Central Plains with a sweeping force. By then, the general situation in the world has been decided. Even if Cao Wei saves Jizhou, he will be unable to turn things around.

Liu Yi saw it very clearly and therefore made up his mind that as long as Sima Yi did not move, he would never move. If Sima Yi wanted to rush to the Central Plains, he would lead his troops northward and break through Yecheng for the second time. If Sima Yi wanted to attack here, he would not be able to stand up and wait for him to be exhausted to death!

"But just do nothing like this?" Deng Ai thought it made sense, but wouldn't it be a bit bad if he didn't do anything?

"Are you doing it~" Liu Yi pointed to the map and looked at Deng Ai in confusion: "Are you very idle?"

Liu Yi has been very busy recently. Although the roads in Bingzhou are not as dangerous as those in Shuzhong, they are not much better. Where to build bridges and where to do some designs, these are all problems. Liu Yi has only just made part of the sand table in Bingzhou, and then designed them. Finally, the construction needs to be done. In addition, the steam engine needs to be put into use in Bingzhou. There are many ore veins measured in Bingzhou at present. It is also a person over 50 years old, and the workload is quite large.

"No...no." Deng Ai shook his head quickly. Liu Yi was arresting a strong man for almost no matter how big he was.

baffling!

He frowned and looked at Deng Ai. Liu Yi continued to bring several disciples to the Taihang Mountains and the two major mountains of Luliang Mountains. In addition, Liu Yi also wanted to see if the terraces could be completed. This is a big project. Before there was a steam engine, Liu Yi would not even think about this problem, but now, Liu Yi wants to give it a try.

Of course, I just want to give it a try. The current area of ​​arable land in the Han Dynasty is enough to support the whole world, not to mention that after the victory of this battle, the existing land, agricultural technology, temples and statues built by Liu Yi everywhere, let alone the current population, even if it doubles, it will be able to survive. Therefore, terraces are not necessary for today's Han Dynasty.

It is just for future considerations. If the territory of the Han Dynasty expands further, the food and grass will be consumed more.

Anyway, Liu Yi found that the more he did, the more things that appeared in front of him would become, as if he could never finish it.

...

"What are Liu Yi doing recently?" Yanjin, Sima Yi sat down with some fatigue and ran around for several months. He finally stabilized the Wei Dynasty's government. The emperor returned to Yecheng. Sima Yi set up more than a dozen camps outside Yecheng, just to avoid the situation like this last time. After a few months, he was not idle.

"According to detailed reports, Liu Yi is starting to build workshops in Bingzhou, Hanoi and other places to dig minerals." Sima Shi looked at his father with some concern. He suddenly realized that his father not only had a haggard face, but also seemed to be a little older than before.

"I'm going to do these things again..." Sima Yi rubbed his temples with a headache. He was really eager to fight with Liu Yi now, but he had also seen the Han army defense line outside Yanjin, and there was no way to take advantage of it. He originally wanted to try to lure Liu Yi out, but he ran to the rear to carry out construction!

What should I do when I encounter an opponent who is not doing my job? Sima Yi has a headache.

If we continue to waste this, the battles in the Central Plains will probably be over.

"Father, the son sent a letter back yesterday, and Sun Quan seemed to have intentional action." Sima Shi handed Sima Zhao's letter to Sima Yi and said, "If Sun Quan sends troops, will there be a turning point?"

"At first, now..." Sima Yi shook his head with a wry smile and said, "Then Pang Tong had intended to lead Jiangdong into the game, that is to say, Jiangdong sent troops. In Pang Tong's plan, do you think that with Pang Tong's ability, if you are not sure, will you do this?"

If Sun Quan actively cooperated at the beginning and attacked the Han army from both sides, the outcome of this battle was hard to say. After all, Jiangdong was not very different from the Han army in terms of equipment. In the early years, when the two countries were in a stalemate, the Han Dynasty sold some weapons every year and Jiangdong exchanged various ores. There was a gap, but it would not be too far apart. Even if those weapons were eliminated by the Han army, they were stronger than ordinary weapons.

In other words, it is basically hopeless to expect Cao Shuang and Sun Quan to join forces to defeat the Han army and then go back and forth to help Jizhou, and there is still waiting for rescue here.

Sima Shi looked at Sima Yi with some bitterness: "Then..."

"You have to defeat Liu Yi first!" Sima Yi sighed. Cao Shuang couldn't count on him and could only rely on himself. But it seems not so easy to defeat Liu Yi now. Liu Yi made up his mind to drag him down. When the Central Plains War ended and Cao Wei was unable to make a comeback, the Han army gathered troops to surround him. No matter how awesome Sima Yi was, he could not face Liu Yi again and fight with Pang Tong.

This incident also shows that Liu Yi is not a pedantic person who only knows how to defend and not attack. He really made him recognize the opportunity. That move must be thunderous. When it comes to Yecheng, Sima Yi is a little scared. If he hadn't defeated Li Yan quickly, then now, he would probably have a different situation.

Defeated Liu Yi?

When Sima Shi heard this, he felt inexplicably confused. This seemed to be not easy to do.

"What are your plans for my father?" After a while of silence, Sima Shi looked at Sima Yi.

"No." Sima Yi shook his head. He thought about all the ways he should think. Liu Yi himself is not weak. The most important thing is to be alert and not take action easily. Especially after this incident, Sima Yi was sure that Liu Yi had made up his mind to push the Wei State. In this case, it would be a great temptation to Liu Yi and show the court, so that Liu Yi would not be moved even if he saw the opportunity to directly destroy the Wei State.

Facing such an opponent, Sima Yi didn't know how to start.

"Then..." Sima Shi smiled bitterly and said, "How should I do this?"

"Strong attack!" Sima Yi was silent for a while and said, if it were not forbidden, he would not have made such a bad move, but the problem now is that he is the one who cannot afford it. Sima Yi cannot place his hope on Cao Shuang and expect Cao Shuang to defeat Pang Tong?

"Strong attack?" Sima Shi looked at Sima Yi and frowned.

"No, attack hard!" Sima Yi nodded and said, "Take out all the captured siege equipment and weapons and armor, and first push down the stone formation. With these weapons, I want to fight Liu Yi's military strategy!"

The big man's catapult can destroy the walls of the stone formation, and the effect is just like an ordinary catapult to smash the wall. As long as a stone formation is knocked down, he will be qualified to challenge Liu Yi. According to Sima Yi's speculation, Liu Yi does not have many soldiers at this moment. After seizing a batch of equipment, Sima Yi felt that he was still qualified to fight with Liu Yi, especially in this case where the troops were very different, without those stone formations, he might not lose!

"Here! I'll go prepare now!" Sima Shi nodded and said.

The next morning, Sima Shi and Guo Huai commanded their troops and pushed the catapult cart to the formation and began to attack the stone formation. Hundreds of stone bombs were smashed down, and the stone formation began to appear constantly. The Han army on the internal arrow tower wanted to stop it, but the range was not enough. They could only watch the stone formation being repeatedly shattered by the opponent bit by bit.

Deng Ai immediately ordered people to withdraw from the stone formation and be prepared for the fortifications made in advance. At the same time, he ordered people to invite Liu Yi over.

"It seems that Sima Yi is going to attack!" Liu Yi looked at the formation opposite and shook his head and smiled.

"Governor, what should I do now?" Deng Ai frowned.

If the stone formation is destroyed, there will be no danger in Hanoi.

"Then build another one and let him slowly destroy it. With these ruins, it will take a lot of effort to just send the catapult to come over, right?" Liu Yi looked at the fierce Wei army opposite and said distractedly: "In addition, in order to avoid Sima's old man's trick, you immediately send someone to monitor the surrounding stone formations and rivers, but if something is strange, immediately send the message with beacon fire and wolf smoke."

"Here!" Deng Ai nodded and agreed. Liu Yi's thoughts were very clear, but he didn't fight head-on and dragged it until the end of the Central Plains war. Although it was a bit bad, Deng Ai felt that it would be better to win than to be almost wiped out by others like last time.
Chapter completed!
