Hua Tuo's promise to Liu Yi to go to the Yuxiang Academy to teach apprentices did not spread, but Hua Tuo temporarily stayed in Xiangyang at the invitation of Liu Yi, first, to take care of Guan Yu's injury, and secondly, Liu Yi was worried that if he was hit by an arrow one day, he would have to ask Hua Tuo to help him save his life.

After all, many things on the battlefield are unpredictable, Pang Tong and Guan Yu are the best proof, he doesn't want to die under the arrow one day inexplicably.

"So, most of the diseases in this world are insolvable with the current medical technology?" Liu Yi looked at Hua Tuo, a little speechless.

In history, Hua Tuo was a miracle doctor, and there seemed to be no disease that could not be cured, but now, Hua Tuo, who was passed down by later generations, told himself that there were many diseases, and he couldn't do anything about it...... The truth is so, but there are still some losses and regrets.

"General diseases can be eradicated in the early stage, but when the world discovers them, they are often ......" Hua Tuo shook his head and smiled bitterly: "So over the years, I began to try to study the human body." ”

To put it simply, Hua Tuo is studying anatomy, such as Guan Yu, cutting off all the necrotic carrion, and then conditioning it, which has a feeling of combining Chinese and Western medicine, that is...... The second brother actually became an experiment.

Liu Yi, who got this answer, looked a little strange, in history, the words Hua Tuo said to Boss Cao wouldn't be trying to pry open Boss Cao's brain and study it, right?

For a moment, Liu Yi suddenly felt that Hua Tuo's gaze on him was strange, and he felt like he was being targeted by evil ghosts.

"Don't talk about this, in fact, I think that instead of waiting until the onset of the disease to seek medical treatment, it is better to prevent it in advance, sir, have you ever thought about writing a book that teaches the world how to prevent diseases? For example, how to describe some of the early signs of the disease and then how to deal with them properly? Liu Yi looked at Hua Tuo and asked.

When Hua Tuo heard this, his eyes lit up, obviously Liu Yi's idea was something he hadn't thought of, rather than treating the disease when it happened, it was better to start preventing it when the disease was still mild, which would make it much simpler.

The topic of conversation between the two suddenly increased, and Hua Tuo was obviously a little moved by this idea, and began to prepare.

"What do you say Tinghou and the Divine Doctor are talking about?" In Liu Yi's hall, Zhou Cang and Liao Hua, who came to thank Hua Tuo on Guan Yu's orders, were hung in the living room, and the two didn't feel anything, but they were a little bored, and they couldn't understand what Liu Yi and Hua Tuo had to communicate? Could it be that Liu Yi still understands medical skills? Or does Hua Tuo understand the arithmetic of the Mohists? No matter how you think about it, I don't think these two people have anything in common.

"Tinghou is an extraordinary person, so he must really know some medical skills." Liao Hua was a little uncertain, the ghost knows why Liu Yi was able to chat with a miracle doctor like Hua Tuo, and left Hua Tuo behind, but it was a good thing after all.

"Tired of the two generals for a long time, it is also a mistake." Liu Yi and Hua Tuo finally came out at this time, looking at the two of them, Hua Tuo said apologetically.

"It's okay, I'm waiting here, in addition to being ordered to thank Mr. Xie, there are also things to discuss with the Pavilion Marquis." Liao Hua looked at Hua Tuo apologetically.

"In this case, the old man will retire first." Hua Tuo stood up with interest, although he agreed to Liu Yi to join the Fishing Township Academy as an apprentice, but Hua Tuo was actually quite disgusted by these war things, and he didn't want to participate more.

"Sir, go slowly!" Liu Yi got up and sent Hua Tuo out of the house, and then looked at the two.

"Tinghou, that Cao Jun has moved again, I am worried about Junhou's injury, so I don't dare to say it to Junhou, so I came to discuss with Tinghou." Seeing Hua Tuo leaving, Liao Hua looked solemn and bowed to Liu Yi.

"Oh?" Liu Yi sat down again, looked at the two of them and said, "What's the movement?" ”

"According to the Tanmalai report, Cao's army has gathered heavy troops in the Xinye area, and there are at least 30,000 people, it seems that they want to wave troops in Fancheng."

"Fancheng?" Liu Yi raised his eyebrows when he heard this, not that he was worried that he would not be able to beat him, but Cao Jun had been so entangled, when would he start to build Xiangyang?

As for Cao Jun's idea? Liu Yi probably guessed that Guan Yu was injured and wanted to use this method to make Guan Yu unable to cultivate with peace of mind, right?

Liu Yi is not too sure.

"Yuan Jian." After thinking for a moment, Liu Yi looked at Liao Huadao.

"The last general!" Liao Hua bowed and said.

"You lead a group of men and horses to Zhuyang, snatch Zhuyang back, and then send troops to Zhuyang and plant more flags." Liu Yi thought about it and suddenly smiled.

Now Xiangyang is in the hands of Liu Bei, in fact, the initiative is not in Cao Jun but in Liu Bei, but now that Xiangyang is rebuilt, Cao Jun sees the opportunity, but in fact, Cao Jun's defensive pressure is much higher than that of Jingzhou Army, Xiangfan's side, even if Xiangyang City is bulldozed and ready to rebuild, unless Cao Jun sends troops in a big way, otherwise there are these three walled cities plus Fancheng, and the troops are not weak, it is not easy for Cao Jun to attack it.

The most important thing is that Liu Beijun can also send troops directly from Shangyong, directly copy the back road of Cao Jun, as long as Zhuyang is taken down, no matter whether there are soldiers and horses coming from Shangyong's direction, Cao Jun does not dare to attack again, Nanyang, for Cao Jun, the biggest disadvantage is that the initiative has been taken away, now the initiative is in the hands of Liu Bei, the Northern Expedition to the Central Plains, for the time being, there is no confidence, but if you want to attack Nanyang, Liu Bei is too convenient to send troops here, Hanzhong and Xiangyang send troops on both roads, you can hand over Nanyang Cao Army is difficult to take care of, can only be passively defended.

Zhuyang is only a small pass, although it is easy to defend and difficult to attack, but if there is no backup itself, with the equipment of the Jingzhou army, it is not difficult to take it.

When Liao Hua heard this, his eyes lit up, and he already understood Liu Yi's intentions, so he immediately agreed and bowed away.

Fighting this kind of thing, no one thinks about it, at least Liu Yi doesn't want to, after capturing Zhuyang, if Cao Jun is smart, he will naturally retreat, if he is not smart, then contact Shuzhong, and send troops from Shangyong to directly copy the other party's back road, not to mention taking Nanyang, but plundering the population of Nanyang is not a problem.

"Tinghou, what about me?" Zhou Cang looked at Liu Yi with some expectation.

"You go to Fancheng, cooperate with the defenders to defend the city, remember, only defend and not attack, if he Cao Jun is the head iron, let them attack by themselves, if they don't have the guts, then stay obediently." Liu Yi said with a smile, during this time, he had to help Guan Yu here, and the construction of Xiangyang could only be put on hold temporarily, but it should not be put on hold for too long.

Three days later, Liao Hua led an army to raid Zhuyang, and the news of Zhuyang's breakthrough was transmitted to Cao's army camp.

"Not good!" Cao Ren and Li Dian reacted at the same time, and their faces became ugly.

"This should be Guan Yu's bluff, it is impossible for the soldiers and horses in Hanzhong to arrive so quickly." Cao Ren groaned.

"But if our army continues to entangle here, but it may not be, then Liu Feng and Meng Da are now stationed in Shangyong, and the soldiers and horses can arrive in Zhuyang at any time, if we insist on attacking Fancheng, I am afraid that the other party will directly copy the back road of our army!" Li Dian smiled bitterly.

This kind of thing, if you are not afraid of 10,000, you are afraid of what happens, if it is really Liu Bei who came from Hanzhong, and they are entangled with Guan Yu here, then let alone taking Xiangfan, Nanyang may be lost, he has already lost Xiangyang, if Nanyang is also lost, I really don't know how to face Cao Cao.

In fact, whether it is Cao Cao or Liu Bei, who have been fighting for many years, I am afraid that they do not want to rashly start the war again, really because of this incident, the battle of Nanyang was opened, I am afraid that the result that neither of them wants to see.

Cao Ren heard this, sighed, the campaign has not been very smooth in the past few years, attacking Shangyong, being blocked by the other party in Fangling and not allowing an inch to enter Cao Hong, and Xiangyang in the rear is also lost, and now when he leads the troops to attack Xiangyang, he finds that the situation has changed, and the initiative is captured in the hands of the enemy, that feeling is really not too wonderful.

In the end, Cao Ren still chose to compromise and gave up the opportunity for Guan Yu to be injured, Nanyang had just experienced a large-scale rebellion, and the rear was already unstable, if he insisted on going his own way, Liu Bei really killed him from Hanzhong, and the possibility of holding Nanyang was really minimal, the top priority was to stabilize Nanyang first, and then wait for the opportunity to seize Xiangyang when the time was ripe.

At this time, even if Liu Yi and others deliberately did not let Guan Yu know, Guan Yu was the commander of the three armies after all, and it was not easy to hide such a big matter, so he soon got the news and was ready to go to Fancheng to compete with Cao Jun, but was told that Cao Ren and Li Dian had withdrawn, which made Guan Yu a little dissatisfied.

"Why didn't Bo Yuan tell me about such a big thing?" Back in the barracks, looking at Liu Yi, Guan Yu's tone was a little rushed.

"Don't blame the prince." Liu Yi said with a smile: "Mr. Yuanhua has instructed that the prince and the marquis must not be angry within these hundred days, let alone go to the battlefield, otherwise the arrow sores will recur and the gods will be difficult to save. ”

Guan Yu was still a little unhappy, but in the final analysis, this matter was also for the sake of his injury, and he couldn't blame Liu Yi, so he could only change the topic and ask Cao Jun if he would return when he retired this time?

"At the moment, we don't want to fight, Cao Cao also thinks the same, after all, the war will inevitably take a long time, if you are not sure, how can Cao Cao easily move troops?" Liu Yi shook his head and said: "Unless there is a certainty of victory, Cao Jun will not take the initiative to provoke for a long time." ”

Of course, the premise is that Cao Jun has no chance to take advantage of this, and the three walled cities still have to hold on, at least until the new Xiangyang City is established, they can't be moved, otherwise if Cao Jun catches the obvious flaws, then Cao Ren and Li Dian are not vegetarians, and I am afraid that they will immediately rush over to retake Xiangfan.

Although Liu Yi and others are a little dissatisfied with their own opinions behind their backs, Guan Yu also gave Liu Yi power before, speaking of which, it is not overstepping his authority, everyone is also worried about his injury, although Guan Yu is unhappy, but he is not really harsh on Liu Yi, now that Cao Jun has withdrawn, Guan Yu after discussing with Liu Yi, he urged Liu Yi to build the city as soon as possible, Xiangyang City is not rebuilt for a day, and this side will be unstable for a day.
