In fact, there was no such technique as suturing wounds in this era.

This surgical treatment method is a postmodern technique that Liu Zheng slowly improved after he encountered many wounded soldiers and died on the battlefield, and only after using his modern medical theory to discuss with Zhang Zhongjing.

Because Liu Zheng used some life knowledge to help Zhang Zhongjing improve ancient medicine, it was enough to make these medicines improve a lot, just like now, when he encountered a not huge wound like Lu Qiling, it could be easily treated.

Otherwise, when Liu Zheng first came to the Three Kingdoms world, the level of medical care at that time was quite limited.

Not to mention that it is a very serious injury, even if it is a minor injury, it is difficult to be healed, and it is not called being healed at all, it is basically carried by yourself, even if you carry it, if you can't carry it, you will be taken away by this small wound.

Liu Zheng saw too many people back then, and he was obviously just lightly slashed, but because this knife was iron-blooded, it was easy to cause infection, and the whole arm was necrotic, and then the whole person could not be treated.

What's more, after being stabbed and becoming a wounded soldier, there is a lack of medical treatment and military doctors, and after a long time, he will die directly on the battlefield because of some small injuries.

It is precisely because he has seen too many such situations that Liu Zheng knows the importance of some medical soldiers, if an army is equipped with several medical soldiers or even all soldiers know some treatment methods, then the casualties of their own soldiers can be greatly reduced on the battlefield.

Even a small injury can greatly increase the chances of surviving treatment.

It is very important for a family that some soldiers who should not have died directly can survive under the treatment of these medical treatments.

Lu Qiling was treated by the military doctor who was trapped in the camp, but she quickly bandaged her wounds, but during this time, there were great changes on the battlefield outside.

Because Liu Zheng escorted Lu Qiling back to the military tent, he was delayed in the military tent for some time, and by the time Liu Zheng paid attention to the battlefield again, the battle on the battlefield was about to end.

Although the strength of Guan Yu's soldiers and horses is strong, they are all elites trained by Guan Yu, but the soldiers and horses on Liu Zheng's side are not all wine bags and rice bags, compared to Liu Zheng's early rabble Yellow Turban Army, now the 3,000 soldiers of the trapped camp and 2,000 brocade guards under his command.

Those are the most elite soldiers and horses under Liu Zheng, these horses can be crushed in strength against the elite soldiers under Guan Yu, and most of these horses are cavalry to deal with Guan Yu's infantry, so it is naturally no surprise.

Guan Yu's soldiers and horses, in addition to being able to resist one or two under these soldiers in the camp at the very beginning, as more white horses were killed and wounded, more and more cavalry took the lead in rushing into these infantry battle formations under Guan Yu, which aggravated the casualties of these infantry.

Once their battle formations were overwhelmed and the organized defenses were unable to effectively resist the onslaught of the cavalry, the defeat was as swift as a mountain.

In just three or four rounds of onslaught, more than half of the 20,000 soldiers were killed or wounded.

Guan Yu was fighting with Lu Bu, and after thirty or forty rounds of fighting between the two, Guan Yu still couldn't gain any advantage in front of Lu Bu.

This made Guan Yu's already ugly expression more and more solemn.

Especially when he saw behind him, more than half of the 20,000 troops had been lost, and the enemy's cavalry was still charging here to crush the battle formations one by one.

At the same time, the White Horse Yicong commanded by Zhao Yun had also been lost, leaving only Zhao Yun and a few scattered cavalry still resisting.

If you continue like this, what awaits Guan Yu is a dead end.

No matter how strong his strength is, it is impossible to face the siege of so many soldiers and horses, and while there are still some foot soldiers here who can help him resist the enemy army and delay the time, Guan Yu's heart has already given birth to the heart of retreat.

He didn't have time to think about it, and sold a flaw in the battle with Lu Bu, causing Lu Bu to come forward to attack.

Then he immediately swept sideways by Lu Bu's side, commanding the war horse to calmly avoid Lu Bu's entanglement.

Lu Bu wanted to pursue, but just now he seemed to hear Liu Zheng say about Lu Qiling, so he gritted his teeth and gave up pursuing Guan Yu, but he was worried about his daughter, and turned his head and returned to Liu Zheng's big tent.

Guan Yu saw that Lu Bu did not come to pursue, and quickly killed several enemy soldiers and came to Zhao Yun's side.

Zhao Yun is fighting with Dian Wei at the moment, the two are inseparable, and their strength is comparable, although Zhao Yun is more proficient in riding, but Dian Wei is not bad, plus Zhao Yun has been fighting for a period of time, and his physical strength is serious, and he has already suffered a loss in the face of Dian Wei.

Naturally, it was impossible to defeat Dian Wei on this battlefield, and the two could only stalemate here.

When Guan Yu came here, he immediately joined the encirclement and suppression of Dian Wei, and when Dian Wei saw that the other party had come to help, he was vigilant and did not dare to attack, so he could only take the initiative to defend.

In this way, Guan Yu immediately called Zhao Yun not to fight, and the two fled directly from the battlefield.

Guan Yu and Zhao Yun, who were already at a disadvantage, dared to confront Liu Zheng's soldiers and horses here again.

So just like that, Guan Yu and Zhao Yun fled in embarrassment.

Seeing the commander fleeing, the 20,000 troops brought by Guan Yu were naturally scattered, and their morale was completely lost, leaving only Liu Zheng's cavalry to chase and kill.

In this way, when Liu Zheng cured Lu Qiling and walked out of the big tent, the battlefield was already in a mess, there were not many enemy soldiers left, and the rest were some soldiers who were trapped in the camp, and they were harvesting the remnants of those soldiers.

Before Liu Zheng could care about Zhao Yun and Guan Yu, he saw Lu Bu approaching in a hurry.

As soon as he came to the big tent and saw Liu Zheng, he immediately asked Liu Zheng.

"Your Majesty, I seem to have seen Qiling just now?"

"Brother Fengxian, you came at the right time, just now, I suddenly found that on the battlefield, Lu Qiling, this girl didn't know when she had mixed into the team, and she was fighting with the enemy, if I hadn't found it earlier, I'm afraid that what you see now is a corpse."

As he spoke, Liu Zheng took the initiative to take a step back and led Lu Bu into the big tent.

Entering the big tent, Lu Qiling was already a little more comfortable, and was lying on the desk resting, when she suddenly saw Lu Bu and Liu Zheng walking in together, her face was slightly ugly, and she looked at a loss, knowing that she was going to be counted down by them again.

Lu Bu glanced at the injured soldier in front of him, this was his daughter.
