Li Jie and Jiang Yan entered the palace together. When they saw Lao Zhu again, they found that Zhu Biao and Zhu Zhen were also there. When Lao Zhu saw them in, he immediately smiled and said, "You are here just right. Lao Liu's affairs in the capital are about to be completed. I plan to go to Taijin to hand over the navy tomorrow. You just happened to accompany the prince to send him to Taijin tomorrow!"

"Your Highness is leaving?" Li Jie was also a little surprised when he heard this, and then asked again, "How is Meng's illness? Can you leave Beijing now?"

"Meng Chuang's illness has not yet been completely recovered. It is estimated that it will take a month to recuperate, but it is not a problem. After I take over the Navy, I will practice in Dengzhou for a period of time. I can wait until his illness is cured before meeting me." Zhu Zhen replied with a smile.

The navy has now become an independent arm of the Ming Dynasty, and several important military ports have been established along the coast, Dengzhou is one of them. However, the navy transferred to Zhu Zhen this time was not derived from the Dengzhou Navy, but was drawn from several navies in the south, so it must be completed in advance.

The reason why the Southern Navy was mobilized was mainly because the Southern Navy was recruited from the southern coast. People there were also more accustomed to hot and humid climates and had strong resistance to some southern ones for the first time.

"So that's it!" Li Jie nodded after hearing this, then looked at Jiang Yan. Then the two of them stepped forward together and submitted the written split plan to Lao Zhu.

Zhu Biao was not surprised to hear the plan to split the Jinyiwei. Although he was not there during the discussion that day, Lao Zhu also discussed with him afterwards that, Zhu Biao actually didn't like Jinyiwei very much. The main reason was that he knew that although Jinyiwei was easy to use, if it was not controlled well, it would easily retaliate against its master. However, if the Jinyiwei was split and their power was weakened, this would be a good idea.

Lao Zhu took over the plan and looked at it roughly. After all, this plan was too detailed. If you read it all, it would probably take more than an hour, and there is no time at all.

"I feel pretty good. I will take a look in detail later!" Lao Zhu nodded at last. Although he only looked at it roughly, he also found that the plan was not only detailed, but also the split plan was very clear. From this we can see that Li Jie and Jiang Yan had indeed spent a lot of effort on this.

"Thank you Your Majesty!" Li Jie and Jiang Yan also responded immediately.

"Father, we will send my sixth brother to Taijin tomorrow. Do you have any instructions?" Zhu Biao stepped forward and asked. When Zhu Zhen left, he would stay at the sea. Even before he captured Annan, he would never return to Beijing, so Zhu Biao asked this question.

Lao Zhu was silent for a moment when he heard this, and finally said, "What you should say during this period is almost the same. I have nothing to give me any advice on anything else. Lao Liu, you go to Annan here, the conditions are harsh and miasma are rampant. You should take care of yourself!"

When Lao Zhu spoke at the end, he also showed a look of reluctance on his face. The older he is, the more he is dependent on family affection. Even Lao Zhu is the same. Although Zhu Zhen is not his favorite son, he thought of letting him go to a place like Annan with a harsh environment, it was normal for Lao Zhu to feel reluctant to leave.

When Zhu Zhen saw that his father showed his family affection, he also showed an excited expression on his face. He immediately stepped forward and knelt down a few steps and said, "Father, as a prince, I should put the overall situation of the country first. It's a pity that my son will not be able to be filial to his father's knees in the future. I hope you will take care of yourself!"

Looking at the deep love scene of father-son in front of him, Li Jie was also a little moved, but when he heard the four words "miasma" just now, he felt a little uncomfortable. He wanted to speak, but he felt it was a bit inappropriate.

After finally waiting until both Lao Zhu and his son calmed down, Li Jie stepped forward and said, "Your Majesty, I have something to report!"

"What's the matter?" Old Zhu asked, clearing his throat.

"That's right. Last time I accompanied the prince and the King of Chu to meet Xu Feng from the Qiuzhen Academy. Because of the limited time, many of Xu Feng's achievements were not available. For example, the epidemic of miasma, he developed a lot of experience!" Li Jie said to report.

"Oh? He has a way to treat the epidemic caused by miasma?" Old Zhu asked in surprise when he heard this.

"This... I really can't answer this question from Your Majesty." Unexpectedly, Li Jie smiled bitterly when he heard Lao Zhu's question.

"What's hard to answer? If you can cure it, you can cure it. If you can't cure it, you can't cure it. Can't he be sure of it himself?" Old Zhu frowned and asked again.

Miasma caused an epidemic is not a small problem. In fact, the reason why the Ming Dynasty was unable to advance troops in Yunnan and Guizhou was mainly due to the local environment. Especially the epidemic caused by miasma often paralyzed a large army. The most serious one may even cause a tragedy of annihilation. The environment in Annan is even worse than that in Yunnan, so miasma caused an epidemic is also Lao Zhu’s most worried issue. Even if he advances from the sea, this problem cannot be avoided.

"Your Majesty, miasma is actually not a single disease, but all epidemics caused by heat and humidity are collectively called miasma. Miasma was even initially a poisonous gas that could cause human diseases due to dampness and heat stagnation. Later, it was extended to diseases. Among these epidemics, the most common one is malaria, and Xu Feng has researched the cause of malaria!" Li Jie replied again.

When Zhu Zhen went to the academy last time, Xu Feng didn't know that Zhu Zhen was going to attack Annan. After all, this was a military secret and Li Jie could not tell him, so he did not show the research results related to malaria. Li Jie didn't think of this at that time, and he suddenly remembered it until now.

"So that's it. I know malaria. I didn't expect it to be a kind of miasma. But Xu Feng is really sure to cure this disease?" Old Zhu nodded first, and then asked again.

Malaria may be a minor disease in later generations, and as long as it is treated in time, it will not happen. However, in this era, malaria is an infectious disease with extremely high mortality rates, especially in a densely populated place like the army. Once malaria appears, it almost means that the army has lost its combat effectiveness in a short period of time.

"Your Majesty, it's a coincidence that the causes of malaria are the same as those of Meng Chuang. They are caused by a parasite, but the parasites of malaria are very young and cannot be seen at all by human eyes. They can also be transmitted by mosquitoes. There are many mosquitoes in the south, so it's so easy to break out of malaria!" Li Jie explained with a smile.

"Malaria is actually caused by a kind of insect!" Zhu Biao and Zhu Zhen next to him were shocked when they heard this. This was something they never expected.

"How should I treat this disease?" Lao Zhu asked again. He was not interested in the cause of the disease. No matter what the cause, it is true that the disease can be cured!
