Li Yan's death was quite decent, and after Liu Yi got what he wanted, he didn't embarrass Li Yan anymore and gave him a happy death.

As for why he wanted Huang Hao's handle, Liu Yi also felt that although Huang Hao behaved respectfully to himself, from a historical point of view, he was also a villain, prepared, and at a critical time, it might come in handy.

"Governor, we've been guarding here?" On the third day after Li Yan was executed, watching Liu Yi start to build various dock forts around Mengjin, Deng Ai couldn't help but ask, according to Liu Yi's current plan, after building the dock forts, he will be ready to go to Bingzhou to open the wooden track, this battle has not yet been fought, how do you feel that Liu Yi wants to change careers?

"The fighter plane is lost!" Liu Yi proofread the map and said without looking back: "You can't rush in now, we are here, the Wei Dynasty or Sima Yi will not dare to move, but now there are 70,000 soldiers and horses, do you expect me to be able 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 New Year, at this time, even if there is a trick Liu Yi will not use, the victory has been mastered, as long as Sima Yi is firmly watched, and the war in the Central Plains is over, the final victory will be in hand.

The most important thing now is stability, he is here to kill Sima Yi, with Wei Yan joining the battlefield, Cao Shuang is now surrounded by three sides, Xingyang, Chenliu and other places have fallen one after another, which also makes Cao Shuang's current situation quite embarrassing, the grain road will not be broken, after all, there are still large areas in the Central Plains belonging to Cao Wei.

But there is no danger to defend, the Han army is in an attack position, although Cao Shuang has many soldiers and horses, but it has gradually turned to passive defense, and the impact of the Wei court being broken by Liu Yi is also here, if Cao Shuang suffers a big defeat, then the Han will swallow the Central Plains with a sweeping momentum, when the time comes, the general trend of the world has been decided, even if Cao Wei keeps Jizhou, he will not be able to return to the sky.

Liu Yi saw it very clearly, and therefore made up his mind, as long as Sima Yi does not move, he will never move, if Sima Yi wants to rush to the aid of the Central Plains, he will wave his troops to the north and break through Yecheng for the second time, if Sima Yi wants to attack here, then he will not be able to hold out, waiting for him to be consumed to death!

"But just do nothing?" Deng Ai thinks it makes sense, but if you don't do anything, isn't it a little bad?

"I'm doing it~" Liu Yi pointed to the map, and looked at Deng Ai suspiciously: "Are you very idle?" ”

Recently, Liu Yi has been really busy, although the road in Bingzhou is not as sinister as Shuzhong, but it is not much better, where do you need to build bridges, where you need to do some design, this is all a problem, Liu Yi has just made a part of the sand table in Bingzhou, and then designed, to the final construction, all need to be calculated, in addition, the steam engine also needs to be put into use in Bingzhou, and the current measured veins in Bingzhou are not ordinary, and they are also over fifty years old, and this workload is a lot.

"No...... No. Deng Ai hurriedly shook his head, Liu Yi has caught strong men recently, regardless of size.

Be all abroad!

Frowning and glancing at Deng Ai, Liu Yi continued to take a few disciples to start designing around the two mountain ranges of Taihang Mountain and Luliang Mountain, and 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 have thought about this problem, but now, Liu Yi wanted to give it a try.

Of course, it's just a try, the current cultivated land area of the Han is enough to feed the whole world, not to mention that if this battle is won, the existing land plus agricultural technology and the temples and statues established by Liu Yi everywhere, not to mention the current population, even if it doubles several times, it can be fed, so the terraces are not necessary for today's Han.

It's just for the sake of the future, if the territory of the Han Dynasty expands outward, the consumption of grain and grass will be greater.

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

……

"What has Liu Yi been doing lately?" Yanjin, Sima Yi sat down a little tired, after months of running, he finally stabilized the government of the Wei Dynasty, the Son of Heaven returned to Yecheng, and Sima Yi set up more than a dozen camps outside Yecheng, just to avoid the recurrence of the situation like last time, and after a few months, he was not idle.

"According to the detailed report, Liu Yi is starting to build workshops in Bingzhou, Hanoi and other places to dig mineral deposits." Sima Shi looked at his father with some concern, and he suddenly found that his father not only looked haggard, 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 little headache, he really wanted to find Liu Yi for a decisive battle now, but he had also seen the Han army defense line outside Yanjin, and there was no chance to take advantage of it, he originally wanted to try to lure Liu Yi out, but as a result, people ran to the rear to do a big construction!

What should I do if I encounter an opponent who is not doing his job? Sima Yi had a headache.

If it continues like this, I am afraid that the battle in the Central Plains will be over.

"Father, the letter came back from the son yesterday, and Sun Quan seems to be intent on moving." Sima Shi handed Sima Zhao's letter to Sima Yi and said, "If Sun Quan sends troops, will there be a turnaround?" ”

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

If at the beginning, Sun Quan actively cooperated, and attacked the Han army on both sides, this battle, the outcome is not easy to say, after all, Jiangdong is not too different from the Han army in terms of equipment, in the early years, when the two countries were like glue, the Han Dynasty would sell some weapons and Jiangdong every year in exchange for various ores, there is a gap, but it will not be too far behind, even if those military uniforms are eliminated by the Han army, but they are also 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 aid Jizhou, and they are still waiting for rescue here.

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

"You have to defeat Liu Yi first!" Sima Yi sighed, Cao Shuang can't count on it, he can only rely on himself, but to defeat Liu Yi, it seems that now it is not so easy, Liu Yi made up his mind to delay, and when the war in the Central Plains is over, when Cao Wei is no longer able to return to the sky, the Han army gathers forces and surrounds him, even if Sima Yi is bullish, he can't face Liu Yi and fight with Pang Tong at the same time.

This incident also saw that Liu Yi was not the kind of pedantic character who could only defend and not attack, it really made him recognize the opportunity, that shot must be a thunderous shot, a matter of Yecheng, until now I think about it, Sima Yi is a little afraid, if it weren't for the fast defeat of Li Yan, then now, I'm afraid it would be a different situation.

Defeat Liu Yi?

When Sima Shi heard this, he felt an inexplicable wall in his heart, this, it seems that it is not easy to do.

"What is my father's plan?" After a long silence, Sima Shi looked at Sima Yi.

"Nope." Sima Yi shook his head, he has thought of all the ways he should think, Liu Yi's own ability is not weak, the most important thing is that he is alert, and he is easy not to do it, especially after this incident, Sima Yi is sure that Liu Yi has made up his mind to push the Wei State flatly, in this case, it is to give Liu Yi a great temptation, show the imperial court, and let Liu Yi see the opportunity to destroy the Wei State directly, Liu Yi will not be moved.

In the face of such an opponent, Sima Yi didn't know how to start.

"Then ......" Sima Shi smiled bitterly, "How should this be done?" ”

"Assault!" Sima Yi was silent for a long time and then said, if it wasn't for the last resort, he wouldn't have made this decision, but the problem now is that he is the one who can't afford it, and Sima Yi can't pin his hopes on Cao Shuang and count on Cao Shuang to defeat Pang Tong?

"Assault?" Sima Shi looked at Sima Yi and frowned.

"Yes, assault!" Sima Yi nodded and said: "Take out the captured siege equipment and weapons and armor, and knock down those stone formations first, with these weapons, I want to fight with that Liu Yi in the art of war!" ”

The Han catapult can destroy the stone henge wall, the effect is the same as an ordinary catapult to smash the wall, as long as a stone henge is knocked down, he has the qualification to call the formation with Liu Yi, and according to Sima Yi's speculation, Liu Yi at this moment, there are not many soldiers and horses, after capturing a batch of equipment, Sima Yi feels that he is still qualified to break his wrist with Liu Yi, especially in this situation of huge disparity in strength, without those stone henges, he may not lose!

"Whoa! I'll go get ready! Sima Shi nodded.

Early the next morning, Sima Shi and Guo Huai commanded the soldiers and horses, pushed the catapult to the front of the formation, and began to attack the stone henge, hundreds of stone bullets smashed down, the stone henge began to appear gaps, the Han army on the internal arrow tower had the intention to block, but the range was out of reach, and they could only watch the stone henge being smashed by the other party little by little.

Deng Ai immediately ordered people to withdraw from the stone formation, to take precautions in the fortifications made in advance, and at the same time ordered people to invite Liu Yi over.

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

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

If the stone henge is destroyed, the land of Hanoi will be in no danger.

"Then build another one and let him slowly destroy it, with these ruins, it will take a lot of effort just to send the catapult over, right?" Liu Yi looked at the menacing Wei Jun on the opposite side, and said disapprerovitically: "In addition, in order to prevent Sima Lao'er from making any tricks, you immediately send people to monitor the surrounding stone formations and rivers, but if there is anything unusual, immediately pass the news with beacon fire and wolf smoke." ”

"Whoa!" Deng Ai nodded in agreement, Liu Yi's thinking is very clear, that is, he will not touch hard, and drag it out until the end of the war in the Central Plains, although it is not very good, but Deng Ai feels that it is better to win than to be almost wiped out by others like last time.

Looking at the figure of Deng Ai leaving, Liu Yi looked at the catapult opposite, and was counterattacked by what he had made, which didn't feel very good, but it depends on whether you destroyed it quickly or I built it quickly.
