Although Doctor Zheng was a commoner, he was very famous in Guanzhong, because of his excellent skills in treating knife wounds, and was quite famous in Guanzhong, Zhennan, especially among the border troops, from the King of Lingnan to the soldiers, he respected him very much. Over time, Doctor Zheng had a much higher vision, but he never expected that the young man in front of him, who was a little shy and smiled, was the prince who stood shoulder to shoulder.

"I'm sorry that I have a poor eye but don't know Mount Tai. I hope Your Highness will never blame you."

"It's okay, I'm just a little better from a background than others."

Dong Zhao advised: "Dr. Zheng, you don't have to care about these false rituals. Qingyan rarely reports his identity on weekdays, just to save unnecessary trouble."

"Your Highness does not hold his own identity and shares joys and sorrows with Lingnan. I admire it very much."

At this time, Qingyan asked out his doubts: "I don't know about the medical skills of Doctor Zheng, the way you used to do a knife and the way you suture me, I just saw you, and I have never heard of it."

After hearing this, Doctor Zheng explained: "Your Highness has good eyesight. My medical skills are taught by a master. I don't know who the master is named."

"Oh? Why don't you even know your name?"

"Although I am obsessed with the technique of apricot forest, my medical skills are still mediocre until I was in a state of confusion. That year, I went up the mountain to collect herbs and suddenly saw an old man riding a green cow. When I saw his crane hair and a childish face, I couldn't help but feel amazed, so I went up to ask, and the old man just smiled and threw half of the broken book to me."

"Because of the marvelous scene, I didn't notice when the other party left. It was too late to find it again."

Qingyan was a little surprised. He didn't expect that Doctor Zheng would have such an adventure. "Then are you learning this skill from which fragment?"

"To be ashamed, although this fragment is only a few pages, I have only understood two or three out of ten in the past ten years." Mr. Zheng's tone was very melancholy.

"A few pages of the fragments, only comprehending two or three out of ten can be such medical skills. It seems that the old man with a long hair and a young face must be extraordinary."

Mr. Zheng focused on the key point, "What Your Highness said is very true. These few pages of fragments seem to be ordinary in his eyes. I believe his medical skills must have reached the pinnacle."

"I don't know where you met this old man. When I have the chance, I really want to try my luck. At that time, I will capture him to open a clinic in Jinling. I will not be able to have a big fuck."

"Near the southern part of Wuling Mountain, but I also want to remind Your Highness that although the old man has a long hair and a young face, he is still in his seventies. It is unknown whether he is still alive." Doctor Zheng knew that he was just a joke and didn't care.

Qingyan just asked casually, and when Lingnan was in trouble, he would rush back to Jinling as soon as possible to prepare for the matter of the rank of the lord. Of course, he would not really go to Wuling Mountain to find an old man riding a bull.

After a day of intense and busy treatment, all the wounds of seriously injured people have been treated. Qingyan and Dong Zhao can also stroll in the injury camp and enjoy a rare time together.

The two of them were linked together and did not care about the strange gazes around them. Many people didn't know what the young man next to the princess was and how he was so close to the princess.

"Am I dazzled? Is our princess's hand being held by a soldier?"

"You are not dazzled, and I can see clearly. By the way, aren't our princess not interested in the young generals in the border army? Why was he taken down by a young man in the end?"

As the two of them got farther and farther away, several doctors gathered together and muttered quietly.

"I really don't know. The princess is not ordinary soldiers, but the noble prince who stands side by side." The soldiers lying on the wooden bed were very funny to the rare strangeness of the few people.

"Side by side the prince? He is the prince who killed seven enemy generals?"

The injured soldier looked proud, "It seems that you don't know anything. I have been following His Highness to guard the northern section of the walls in the past few days. Four days ago, His Highness personally led more than 30 brothers to push back hundreds of Nanyi soldiers. Hehe... I am one of the members of that time. If I hadn't been careless last night, I would have been able to kill a few Nanyi monkeys with His Highness."

"There is still such a thing? Come on, hurry up and talk to us."

"That's right, it was cloudy that day..."

--------------------------------------------------------------------------------------------------------------------------------

Nanyi camp, in the commander's tent.

Du Ming used a linen to tie his forehead hard, and then he woke up a little.

"When is it now? How long will I be in a coma?"

"Report to the general, it's time now, you've been in a coma for two days. Fortunately, the general is in great fortune, otherwise the general will really not know how to act."

Du Ming leaned his back against the bed, and asked hoarsely, "How many troops can our army fight now?"

"After several days of unreserved research, our army suffered heavy casualties. Now there are only about 35,000 soldiers to fight. If some of the lesser injuries are included, it is almost more than 40,000."

"Forty thousand..." Du Ming murmured at the lamppost, wondering what he was thinking.

The deputy general did not dare to disturb him, so he stood aside respectfully.

"At noon tomorrow, I will order the three armies to attack the key points without investing too much force, but the momentum must be sufficient. When the gold is heard, the whole army retreats south at midnight." Du Ming's voice was slow and powerless.

The deputy general naturally knew Du Ming's intention. Tomorrow's investigation is to retreat south to cover up. If he does not act like a gesture, the Lingnan border army is likely to come after him.

"The last general will receive the order, and I hope the general will take care of his health."

"Go."

In the handsome tent, Du Ming looked at the flames in the lamp post, staring blankly.

At the same time, Qing Yan and Dong Polu looked into the distance, and the soldiers around them were all five feet away.

"Two days have passed, and the enemy has not attacked again. What are your plans?"

"Reporting to the prince, it is naturally carried out according to the original plan."

"No matter whether you succeed or fail, you must return safely."

"Qingyan remembers it."

---------------------------(I'm a dividing line)

At night, the walls of Zhennan Pass were still as bright as daytime. The surviving border soldiers looked to the west with vigilance, beware of the enemy's attack again.

A rope suddenly fell in the darkness of the northern section of the Guan Wall, and two men in black fell steadily on the ground.

"Ouch..."

"You were screaming at the moment of coming down. Why did you tell you before?"

"Isn't this not paying attention to the foot and stepping on a head."

"Be smart."

The two were neither others, but Qingyan and Dong Jin. They slowly sneaked to the west, with their paces fast.

When he came to a hill, Qingyan pressed Dong Yan to the ground, and he also lay beside him and motionless.

Dong Yan did not dare to spit out the soil, and slowly looked upwards. He saw a Nanyi sentry showing half of his head and looking vigilantly at the direction of Zhennan Pass.

"There are too many hills here, and the whistle cavalry is not as fast as the sergeant's flag. This should be the first sergeant of the enemy. Let's touch it slowly, remember not to alert the snake." Qingyan attached to Dong Yan's ear, his voice was extremely light, "When I kill this sentry, you must be alert all around. If you find that there are still secret whistles, you must do your best to kill them."

Seeing him nodding, Qingyan took the lead in touching upwards, and Dong Qi followed closely behind.

The hills here are not high, at most only a few feet, but for the two, they seem to be the heavenly palace on the sky.

The Nanyi sentry was a little heavy because of his long concentration. He took out a betel nut from his arms and chewed it in his mouth.

At this time, he felt the smell of betel nut very strange and was about to vomit onto the ground. A feeling of powerlessness came and crawled to the ground.

Qingyan didn't look at the sentry whose throat was pierced again, and quickly threw it under the east slope of the hill.

"How about it, are there any secret whistles?"

"Not noticed, it seems that the enemy's personnel are tight."

"Hurry up, just like you and I just touch a hundred feet outside the enemy camp."

Half an hour later, looking at the village gate less than one mile away, the two of them retracted and hid on the east slope of the last hill outside the enemy camp.

"Sure enough, this camp is easy to defend but difficult to attack, but it is not impossible. The terrain of the north slope is the slowest. When you go back, you are two miles away from the enemy camp. Remember to act carefully. It is better to spend more time than to let the enemy discover it." Qing Yan whispered.

"I know the pros and cons, so you must be careful. If you are discovered, run away."

"I thought I was clumsy like you, go quickly."

After Dong Yan ran back not far away, Qingyan had already put the coat of the dead sentry on his body, picked up the flag and climbed to the other side of the hill.

Because he didn't know when the enemy troops communicated with flags at a certain time, Qingyan could only half turn and scan the distant village gate with his light.

As time passes by bit by bit, Qingyan carefully deduces it in his heart and is careful to prevent loopholes.

Before the war started, Dong Polu asked what strategy he had to defeat the enemy, and he answered that he had a feasible plan.

fire!

The 100,000 troops in Nanyi occupy a very wide area. Because Lingnan is like spring all year round, there are countless weeds on the hills. In addition, there are many south winds at night in early spring, setting fires from the north of the enemy camp will spread rapidly throughout the entire camp.

But this was not a plan that shocked the world and was so heartbroken that Du Ming, as the general of Nanyi, naturally thought that the tunnel was built here, so he could only build the camp on this huge hill.

Du Ming was not unprepared. The entire camp was as solid as a rock. There were countless trenches and arrow towers that were easy to defend but difficult to attack. However, this was also before the war began. Now the enemy's casualties had already exceeded half of their casualties, and their morale was sluggish. No matter how many defensive measures were used, they could not protect the soldiers who had lost their fighting spirit.

And the most important point is that the water source closest to this place is located just outside Xisanli.

Various conditions create the necessary prerequisite for the use of fire plan, which allows Qingyan’s pre-war ideas to be implemented.

At this time, seeing a sentry above the village gate shaking the torch, Qingyan turned over and raised the flag to signal.

Whether Nanyi can be repelled so that it will lose all its strength and dare not go north within twenty years, just look tonight!

A figure appeared behind a hill in the west, and then came one by one, and when these people led their horses to the foot of the hill, Qingyan no longer hesitated and slipped down.

"Your Highness, everything is ready." Shi Zhan handed Mo Xue and Tian Feng to Qing Yan.

"There is still some time before the hour of Hai, and Dong Feng in the north should not be in place yet. Let the brothers take off the cloth on the horse's hooves first."

This 800 cavalry, except for dozens of tiger guards, was the few horse warriors in the Lingnan army. When they were suddenly gathered to follow Shi Zhan and left the city gate, everyone realized that something big would happen. After seeing the young prince, they couldn't help but think of the city under Jinling a few months ago.

At this time, Dong Jian led two thousand elite infantry troops around the north of the enemy camp, and was cautious during this period, afraid that the enemy would find out. When he arrived at the established location, he breathed a sigh of relief.

After counting the time, Dong Yan ordered in a deep voice: "There is still half a cup of tea, so that the brothers can make the final preparations. If anyone loses a piece of thatch or a drop of oil, the military law will deal with it."

The oil in Dong Feng's mouth was naturally not tincture oil, because the fierce battle on the eve of the thorn oil had been consumed. This was the butter that was urgently collected for two days, and it was barely replaced.
