In October, the state was merged, and there was no double country and no double city.

Li Yi cautiously squatted beside Xiaobai, staring at the 1-year-old tiger with his eyes, for fear that he would accidentally fall off Xiaobai's back. On the side, the two sisters, Cai Yan and Cai Qing, stood aside with a smile and watched this scene, talking to each other from time to time, which made Cai Qing feel embarrassed.

It's a pity that Li Yi didn't see this scene, because he was worried. "Big Tiger, it's almost okay, aren't you sleepy? Do you want to drink milk? Li Yi persuaded with a sad face, but unfortunately Dahu ignored Li Yi at all, just sat in Xiaobai's north and kept dancing, and it could be seen that he was very excited.

It's strange to say, Dahu is not afraid of Xiaobai at all, and even dares to grab Xiaobai's beard to play. And what about Xiaobai? Although he screamed in pain, he didn't dare to move at all, for fear that he would accidentally hurt the big tiger. This situation made Li Yi very distressed. Well...... I feel sorry for Xiaobai.

At this moment, Cao Xuan suddenly walked in, saw the scene in front of him, and hurriedly whispered, "Lord, they are back." ”

"Oh?!" Li Yi stood up when he heard this, but immediately reacted, turned his head and looked at Cai Yan with some apologies, knowing that he hadn't been alone with Cai Yan and Dahu for a long time.

"Gentleman, go quickly, business is the most important thing." As he spoke, he pulled Cai Qing to Xiaobai's side, and at the same time hugged the big tiger.

"Just let Xiaobai ......" Li Yi just wanted to say something when he saw this, but when he saw Cai Yan's serious expression, he had to give up, and left with Cao Xing on Xiaobai.

And after Li Yi and Cao Xing left, Cai Yan comforted the crying big tiger while looking at Cai Qing and said helplessly, "Qing'er, you have to work hard, I have helped you create opportunities like this......"

Well, although it is said that it is waiting for Cai Qing and Xu, it is obvious that Cai Yan still can't help but help his sister create some opportunities to enhance her relationship with Li Yi.

"Got it, sister......" Cai Qing replied shyly. Although Cai Qing behaved very directly in front of Cai Yan, when she came to Li Yi's side, she became extremely shy.

Seeing this, Cai Yan shook his head a little helplessly, but he didn't care too much. Because she believes that as long as Cai Qing likes Li Yi, it will be enough, because can Li Yi give Cai Qing happiness? This is something that is not in doubt.

Having said that, Cai Qing and the other women's thoughts, Cai Yong or Qiao Yu and others don't know? Naturally impossible. In fact, in their opinion, although marrying all the sisters to Li Yi is a bit too cheap for him, no matter the character, family background, career or any other aspects, it seems that Li Yi is the most suitable candidate for them.

After all, in the entire Bingzhou, except for a few families in Taiyuan, there is really no one who is qualified to marry Cai Qing and other women. Of course, marrying away from other states and counties is also an option, but Cai Yong and Qiao Yu are also a little reluctant. And what if you get married, what will you suffer? At least here, they can still help watch.

Well, in the end, it was because Li Yi's status was so high that Cai Yong and others felt that even if they married their daughter to him as a concubine, it would not be a big deal.

On the other side, Lu Bu was respectfully reporting to Li Yi the results of the hunt in the north, although during this time, there were surrendered tribes or Hu captives who were sent back to Bingzhou, but Li Yi was most concerned about the actual combat effect of the flying cavalry battalion.

As a result, it can be said that Li Yi was both satisfied and dissatisfied, and what was satisfactory was that he attacked nearly 10 tribes in a row, ranging from more than 100 people to several thousand, and the casualties were only a few hundred. Whether it's marching, advancing or retreating, or whatever, it seems to be pretty good.

Not satisfied, but still because of the hundreds of casualties. After all, it was a full 30,000 flying cavalry troops, and the enemy at most was only a few thousand, but even so, there were still hundreds of casualties, how could Li Yi be satisfied? And what made him most helpless was that many of the soldiers who died could actually be saved if they were treated in time.

"Alas...... If we can form a medical force......" Li Yi thought to himself, and then this thought was a little unstoppable. Until Lu Bu and the others left, Li Yi was still pondering this thought.

It is true that in this era, only the children of the family have the conditions to study the art of Qihuang, but for Li Yi, it is not a difficult thing to obtain medical skills. And most importantly...... "If you look at it purely from the perspective of war, the medical corps does not need to know a lot......"

Speaking of which, in fact, military doctors or similar professions have appeared for a long time, the earliest in the Spring and Autumn Period and the Warring States Period, and this profession also exists today, but the name is different. They were people who specialized in the service of the military, and even in this day and age there were specialized military prescriptions and herbs.

It's just that they are still far from the medical force imagined by Li Yi. Because these so-called military doctors only built a temporary place in the rear as a place for wounded and sick treatment, and the number is very small. If a large-scale war really breaks out, then it is simply impossible to have enough people.

Take today's merger of states as an example, there are 30,000 flying cavalry battalions, 10,000 trapped camps, 10,000 Hun protection battalions, and the strength of various states and counties is about 2,000-10,000. This kind of army of nearly 100,000 people, but there are less than 5 military doctors, and they are basically concentrated in Yanmen and Wuyuan. In this case, if there is a large-scale war, even if they have three heads and six arms, it is impossible to cure them.

Moreover, although these military doctors have a military character, they are actually ordinary doctors, although they cannot be said to be defenseless, but they are also masters who cannot go into battle to kill the enemy. In this way, the problem arises, once a war breaks out, they can only stay in the city or in the safety of the rear, then from the battlefield to the rear, it is likely that many soldiers who did not have to die will die directly on the way.

"That'...... How do you get it? Li Yi had a headache. In this era, medical skills are known as Qihuang techniques or square skills, although most of the children of the family know a little bit, but it is just something that comes with learning, because this profession is one of the lowly professions. Very few people will really study medical skills, even if it is a medical officer such as the imperial physician in the palace, in fact, they are just ordinary scholars.

In this case, it would be a fool's dream to let a scholar engage in this kind of profession, let alone Li Yi's more lofty ideals.
