In Cao Wei's bedroom, an imperial doctor was giving him moxibustion. He saw that Cao Wei's exposed legs were red and swollen, and burning moxa pillars were placed at the acupoints on his legs, but this seemed to be unable to relieve his pain. Cao Wei's face, which never changed color even when facing thousands of troops, was not a trace of blood, his forehead was covered with cold sweat, and his gritted teeth also made painful moans from time to time.

Rheumatism is sometimes good and sometimes bad, especially when it is greatly affected by the weather and is not serious. This disease will not even have much impact on people. However, if it occurs, the joints in the whole body will be sore, especially some large joints, which is even more painful. In some serious patients, even the bones of the joints will deform, which can be said to be very terrifying.

Li Zhang and Cao Ma stood aside and watched the imperial doctor moxibustion. As the moxa pillar burned, it finally relieved Cao Wei's leg pain. However, this method was used to treat the symptoms but not the root cause. So after the imperial doctor took the tools, he reminded Cao Wei to take a rest again, and then he went down to decoct the medicine.

"Let Li Zhang laugh!" Cao Wei's pain at this time also relieved a lot, and his face finally had a little blood. He smiled apologetically at Li Zhang. He called Li Zhang by name, but in fact he didn't treat him as an outsider. In fact, in such scenes as treatment, outsiders would not usually come in, but he let Li Zhang come. From this, Cao Wei almost regarded Li Zhang as his son and nephew.

"Uncle doesn't have to do this. Do you feel better now?" Li Zhang immediately changed his name very well.

"It's better, but the joints of the whole body still seem to be cut with a knife, especially the pain on the legs. Sometimes I really wish I could cut my legs with a knife, so that I could feel better." Cao Wei was lying on the bed and said helplessly. He was a hero for a lifetime, but he didn't expect that he would suffer from this kind of illness when he was old.

Seeing Cao Wei's painful look, Li Zhang couldn't help but sigh. He knew some medicines for rheumatism, but they were Western medicine. There was no medicine in the medicine box on the plane. Even if there were, it was expired now. But then he thought of the medicinal wine he brought, so he immediately said, "Uncle, I got a secret recipe. It is said that it is very effective for this kind of old cold legs. I have also brought the medicine. Do you want to try it?"

Hearing Li Zhang's words, Cao Wei also showed a embarrassed look. After all, how can medicine be taken randomly? However, Li Zhang hurriedly explained again: "Uncle, don't worry, this medicine is not taken, but a kind of medicinal wine, which only needs to be applied to the joints."

When Cao Wei heard Li Zhang say this, he was not good at rejecting his kindness anymore, so he nodded and said, "Okay, then I'll thank you for your kindness!"

At this moment, Li Zhang asked someone to take the medicinal wine he brought, but Cao Ya was still a little worried. It was not that he didn't believe Li Zhang, but that he was worried that if the medicinal wine had any negative effects, it would only make his father even more painful. So he suggested that the imperial doctor see it. Li Zhang was not sure about the medicinal wine, so he immediately agreed.

After a while, the old imperial doctor who went to decoct medicine was invited in. Li Zhang also handed him the medicinal wine and told him the formula. As a result, the old imperial doctor nodded after hearing this, "The medicinal materials used by the Duwei are very symptomatic. I just soaked the medicinal materials in the wine and applied them on my body. This is the first time I have heard of this usage, especially the wine tastes so good."

Not only did the old imperial doctor smell it, but Cao Wei and his son were also frowned by the smell of this medicinal wine. It would be fine if the smell of wine was just. The key is that some medicinal materials were soaked and emitted various strange smells, which was really not very pleasant.

"Since Doctor Huang said that, I'll try it!" Although Cao Wei felt that the medicinal wine smelled bad, he still nodded. So Cao Mai took it himself and poured the medicinal wine into the palm of his hand as Li Zhang said, rubbed it and then applied it to the joints of Cao Wei's legs.

At first, Cao Wei was fine, but slowly he felt that the place where the medicinal wine was applied was warm, and even the previous soreness was greatly relieved, which made him overjoyed and shouted: "It works, I feel much more comfortable!"

When Li Zhang heard Cao Wei say this, he was relieved. It seemed that the medicinal wine was indeed effective. Cao Ma screamed in surprise, and then hugged Li Zhang and kept patting him on the back to thank him, but almost knocked Li Zhang fainted.

The medicinal wine is used externally, while the imperial physician decocted the medicine is taken internally. The two did not conflict. While Cao Wei was drinking the medicine, Li Zhang pulled the imperial physician aside and said again: "Doctor Huang, I heard that Thunder Treasure has miraculous effects on old cold legs. I wonder if you have this medicine?"

"I heard someone say that the Duwei understands medical skills before, but now it seems to be true." Huang Yuyu couldn't help but caress his beard when he heard Li Zhang's words, "Although Thunder Vine is miraculously effective on the old cold legs, this thing is highly toxic, so we dare not use it too much. For example, although there is a little Thunder Vine in my medicine, there are also many antidote drugs. If the Thunder Vine is too much, most people may have life worries if they take it."

"I know that the thunder vine is poisonous, but as far as I know, the thunder vine poison is generally concentrated on the inner and outer layers of skin. As long as these two layers of skin are removed, its toxicity will be greatly reduced. Doctor Huang knows?" Li Zhang said again. This thing was also found by him from the information. In fact, there was thunder vine in his medicinal wine. However, he found that the thunder vine bought from the pharmacy had a highly poisonous skin, so he personally dealt with it for a long time before he dared to use it.

"There is also such a method?" Huang Yuyi didn't know. In fact, the thunder vines they used now are indeed skin-covered, which also makes them extremely toxic, so they dare not use them too much.

"This is indeed true. If Doctor Huang doesn't believe it, you can go back and test it. Thunder Teng has miraculous effects on old cold legs. Increasing the dosage may cure this disease." Li Zhang said again immediately. Of course, he can't guarantee whether it can be cured. After all, the disease of old cold legs is the most difficult to eradicate, but it is definitely no problem to relieve the condition.

Doctor Huang also hurriedly wrote down the medicinal wine that Li Zhang had just brought was more useful than his moxibustion, and he seemed to be very clear about the usage of Thunder Vine, which made him secretly doubt whether they had used it wrongly before?

Originally, Li Zhang came to discuss martial arts with Cao Wei, but Cao Wei had a rheumatism attack and after taking the medicine, he soon felt a little tired. Li Zhang had to instruct the other party to have a good rest and then come out with Cao Mata.

Cao Ma and Li Zhang had not seen each other for several years, so they immediately asked someone to prepare a banquet. Then the two sat opposite each other and began to talk about some old things, mainly some things when they were in Qingzhou. Li Zhang also inquired about the recent situation of Jinshan and Di Qing. Although they occasionally had correspondence, the content on the letter was limited after all.

Jinshan has now become the most famous wealthy businessman in Qingzhou. With the big tree of Cao's father and son, the people on the official side dare not make things difficult for him. Moreover, Jinshan has the means and ability, and he helped Li Zhang build the border market. Now he mainly works as a middleman, purchasing silk and porcelain from merchants from the Song Dynasty, and then exchanging fur, meat, horses, etc. with overseas tribes. Of course, in private, Jinshan also does some disgraceful business, such as helping the Song Dynasty army handle some spoils.

Di Qing has also been promoted to commander of the battalion, with 500 soldiers under his command. This is not Cao Ma's care, but Di Qing's bravery in fighting and made great contributions several times. If he hadn't used military merit to repay the crime, his position might have been higher. Even Cao Wei praised Di Qing, believing that this young man would definitely become a famous general in the future. I cannot praise Cao Wei's vision here. Whether it is Li Yuanhao or Di Qing, he is extremely accurate in his view of people.

"How is the Musketeers? I heard you were out again some time ago?" Li Zhang asked again at this time. He was also paying attention to the movement on the Musketeers side, but he didn't know some secrets in the military.

"The northwest is very peaceful now. Since the last battle, Dangxiang was almost destroyed, no one dared to cause trouble in our Song Dynasty. However, some time ago, the Tubo people in Xizhou were in chaos, so we were transferred to quell the chaos. The Tubo people in the first battle fled. Unfortunately, the court did not allow us to chase us any longer, otherwise we might be able to defeat Longyou!" Cao Mata couldn't help but slapped his thighs hatefully when he spoke at the end.

After Liu E took office, she was relatively conservative about military and political aspects, and mainly allowed the whole country to recuperate. After all, Zhao Heng had a great fuss before, which greatly damaged the national strength and was more conservative in military affairs. As long as the enemy did not violate the border, Liu E had no idea about this at all.

"The court is indeed a little conservative, and maybe there will be changes in the future." Li Zhang sighed immediately. In fact, not only Liu E is conservative, but the ministers in the court are also very conservative. In particular, many civil officials are worried that war will make the generals bigger, so they are also restrained everywhere and do not give the generals the opportunity to expand their territory.

"I hope so, but our northwest is pretty good. Brother Hu Yan is even more idle in Hebei. He heard that the Liao Kingdom has had no time to go south in recent years, so their Hebei Musketeers can't even find a chance to fight, so they can only practice hard." When Cao Mata mentioned Hu Yan's trust, he also showed a gloating expression on his face. Although they were in good terms, they were both generals of the Musketeers, so they naturally had a comparative mind, and now he was obviously the one who had the upper hand.

Li Zhang also knew about Hu Yan Shouxin's situation, because Hu Yan Shouxin wrote many letters to come back to complain, but if the Liao people did not go south, he had no choice.
