Hua Tuo's surgical operations were originally completed independently, but after he recruited a wide range of disciples, Lan Tian suggested that multiple people cooperate, with one person performing the surgery and the others assisting.

Minor surgery on the arm is not complicated, and one assistant is enough. However, if you want to treat complex conditions in the internal organs, multiple people are needed to help.

Huisheng used a knife to cut off Guan Yu's swollen and blackened arm flesh, and black blood dripped down. Senior brother Qi Shi took it on a plate, and soon there was a small plate.

Guan Yu's expression remained unchanged, he drank wine and ate meat with the generals in the camp, and praised Gan Ning's martial arts prowess.

The pain of cutting through the flesh was only part of the pain, but the pain of scraping the bones with a knife was on another level. Seeing how calm Guan Yu was, Huisheng gently scraped away the poisonous juice with his knife.

The tent became quiet at that time, only the sound of rustling and scraping could be heard.

Guan Yu suddenly said: "Don't stop drinking. There are not many opportunities to have banquets before the army. In the future, you have to kill the enemy with all your heart."

"Only." All the generals replied in unison.

Who can know the pain of cutting one's skin? The generals in the tent admired Guan Yu even more.

Guan Yu continued: "Cao Ren will definitely defend the city more firmly when he sees that I have poisoned arrows. After General Liang brings the equipment back, we will start an all-out attack. Fancheng has been soaked in water, and the defense should be much worse than before. Xingba will be responsible for attacking Dongba."

Door..."

Guan Yu was drinking wine and arranging siege operations. He was talking and laughing calmly and seemed to have forgotten about scraping bones to cure poison.

Within half an hour, Huisheng scraped the bones to cure the poison, applied medicine and sutured with needle and thread. Guan Yu remained motionless during the whole process, as if the arm was not his.

Although Qi Shi diligently wiped Huisheng's sweat during the operation, Huisheng's back was already soaked.

"The general is truly a divine man." Huisheng bowed his hands in obeisance after the operation.

Qi Shi also added: "My brothers have treated many patients, and there has never been anyone as powerful as the general..."

Guan Yu then turned his head, moved his arm slightly, laughed and said, "It really doesn't hurt anymore. Mr. Hua's feet are indeed extraordinary. Xingba, please reward me well."

"Wei." Gan Ning cupped his fists.

"You don't have to be like this, Your Majesty. It's our honor to be able to heal your wounds." Huisheng bowed his hand and said goodbye.

Qi Shi then collected the utensils and medicine boxes, and Hui Sheng bowed to everyone and exited the tent.

Looking at the two people leaving, Guan Yu said thoughtfully: "If it is true as Ziyu said, doctors are included in the combat organization, the combat casualty rate will be reduced a lot."

"Soldiers can go to the battlefield after two months of training, but it takes at least several years to train a good doctor. It is not easy to set up a high-level medical camp. However, my husband founded a medical school, which is equivalent to the Guangzhou Academy. This ideal should be realized in the future.

." Gan Ning replied.

Guan Yu nodded, "When Zhong Ling grows up, he may have his own medical team."

A few days later, Liang Tai returned with siege equipment. Guan Yu immediately launched a general attack on Fancheng from three sides. Cao Ren immediately mobilized the defenders to climb to the top of the city to defend. The two sides refused to give in to each other, and the battle scene was very fierce.

Cao Ren shouted angrily from the top of the city: "Isn't Guan Yu poisoned by an arrow? Why isn't he dead yet?"

Xu Huang was very speechless, while Niu Jin said awkwardly: "The main reason is that he missed the vital point... You can try to insult Zhou Yu, which will cause Guan Yu's blood to rise, making him angry and causing the wound to burst..."

"Then send someone to scold him." Cao Ren said angrily, then turned to look at the others and asked: "Who is Gan Ning in the east? The casualties and pressure in the east are actually similar to those in the south where Guan Yu is sitting."

Man Chong twirled his beard and said: "This man seems to be a bandit. He killed many generals in Jiangdong. Now he is the governor of Changsha..."

"When will these Jiangdong rats send their troops?" Cao Ren yelled.

When Cao Ren heard about Jiangdong, he came to anger. After the Seventh Army of Yujin was overwhelmed and surrendered, Cao Ren sent scouts to ask for help from Cao Cao. In the past two days, the scouts came back with orders to stay in Fancheng and wait for help, because Sun Quan had promised to attack Jingzhou.

As long as Cao Ren is restrained in Fancheng and Sun Quan successfully attacks the rear of Jingzhou, Guan Yu's lone army in the Northern Expedition will be attacked from both sides. Cao Cao sends Yin Shu and Zhu Gai with 20,000 troops to rescue him. If Guan Yu cannot be stopped, Cao Cao will personally lead his troops south.

.

"Well... based on my understanding of Sun Quan, if we don't fight Guan Yu to a bloody head, he will definitely not send troops." Man Chong replied.

Cao Ren gritted his teeth and said, "Biyan is really courageless."

"The most critical thing is the issue of food and grass. I don't know how long Xiangyang can last. The food reserves in Fancheng have been hit by floods, and the rest can only last two months..." Man Chong said worriedly.

Cao Ren was surprised: "Why is there so little? I remember that the food in Fancheng was enough to feed the previous defenders for two years."

"After General Xu arrived, the number of our defenders increased. Mainly because of the floods in the past few days, which flooded many granaries. I have already calculated the combat attrition in advance..." Man Chong shook his head.

Cao Ren frowned, "I almost forgot that Gongming's soldiers were all caused by Zijian's drinking and delaying the supervision of food and grass transportation in the rear. Now he sends Yang Dezu (Yang Xiu) to Xudu to plead guilty, what's the use?"

"Uh..." Man Chong thought that if Cao Zhi got drunk and got into trouble, he must have something to do with the prince in Yecheng, so he didn't dare to continue the topic.

Guan Yu attacked the city for several days and saw that Cao Ren defended the city tenaciously. The attacking Jingzhou army suffered heavy casualties.

Fan City was soaked loose and there was a possibility of breaking the city at any time. Guan Yu did not want to give up this opportunity, but considering that Cao Cao would send reinforcements, he immediately called the chief secretary Liao Hua.

"Yuanjian, please quickly send someone to Jiangling to pass on my general's orders and send another 10,000 troops and horses to Fancheng to join the battle."

Liao Hua was shocked when he heard this, "There are only about 10,000 Jiangling defenders. How can we defend if we take away another 10,000? What's more, we have just sent back 20,000 prisoners. If something happens, the consequences will be disastrous."

Guan Yu stroked his beard and said: "We have to believe in Commander Xu. Furthermore, the rear area of ​​Jingzhou is peaceful and nothing will happen."

"General Gan has taken away 90% of Changsha's troops. Only Governor Su's 3,000 naval troops are left on the Yangtze River. General Guan, if you spare the Jiangling garrison, if Lu Xun has any evil intentions..." Liao Hua was very worried.

Guan Yu frowned and said, "Follow my general order. I have transferred Gan Xingba to Fancheng for a long time, and I have never seen Lu Boyan showing any evil intentions. What's more, with Yuan Zhi and Ziyu in the south, there is nothing to worry about."

"Wei." Liao Hua had no choice but to accept the order.

After receiving the order, Xu Shu immediately sent out troops and followed the warship sent to pick up the people to go north to Fancheng.

At this time, Jiangling City was under huge pressure on city defense and logistical supplies, and the 20,000 prisoners could not be digested in a short period of time. He imprisoned Yu Jin and other generals and military attachés in prison, and left 5,000 prisoners in the custody of the city defense army, while the rest were transferred to custody.

They were resettled in batches in Wuling and Changsha.

The food and grass on the front line of Fancheng mainly came from Changsha County. After Gan Ning left, the remaining officials were not doing well, so Xu Shu took advantage of the opportunity to escort the prisoners and went to Changsha to supervise the food supply.

Jiangling's every move was under Jiangdong's surveillance. When he learned that Guan Yu had really taken a large number of defenders to Fancheng, Wu Qi was overjoyed and found Lu Xun.

"Grand Governor, the time has come."

"It's time for my lord to set off from Chaisang. I still need to confirm it one last time." Lu Xun answered affirmatively.

"General Lu, you are really cautious." After Wu Qi finished speaking, he went to make arrangements.

Three days later, at Guan Yu's camp in Fancheng, the envoy from Jiangdong came again.

Guan Yu had a busy schedule to receive Sun Quan's envoy, but the envoy issued another empty promise.

Sun Quan once again promised to send troops to help, but there was only thunder and no rain. It had been a month since the last time he promised to send troops, and it felt like a joke.

Guan Yu failed to attack the city and was already unhappy. He felt that he was being played by Sun Quan, so he became furious and said: "How dare you! If Fan City is overthrown, I will not be able to destroy you!"
