Wang Zheng took out the note from the small bamboo tube and read it. He sighed in his heart, but said calmly: "It's not a big deal. It's just that a man named Ming Chongyan presented medicine to Your Majesty. You can go and do your work. Today is your big day, so don't worry about these things."

"I'm leaving now."

Wang Ping'an nodded, didn't ask any more questions, bowed, and left to do his own thing.

As for Ming Chongyan, both the New and Old Book of Tang record that he offered medicine to cure Li Zhi's headache, or to be more precise, he suppressed and relieved Li Zhi's headache.

However, such an important person died inexplicably, which subsequently caused a complete break between Wu Zetian and Li Xian.

With both the Medical College and the Imperial Hospital at a loss as to what to do, what other medicine could be used to relieve Li Zhi's headaches?

All Wang Zheng could think of were drugs like headache powder from later generations, which were addictive. This kind of drug only treated the symptoms and not the root cause, and would gradually produce antibodies. In the end, the dosage would increase, and Wang Zheng would have to use more and more drugs. It was not that Wang Zheng didn't know this, but he just didn't dare to give it to Li Zhi.

Wang Zhen has been wandering on the sea for so many years. After completing the exploration of the South China Sea, he went to India and found that although he could develop trade there, there was nothing new.

Finally, Wang Zheng wrote back to Da Wu: Don’t worry too much, just do your own thing well.

"Um."

"Your Majesty has summoned the Grand Steward to see you."

Qibi Ming hesitated for a moment and said, "Your Majesty has ordered that if the chief steward asks about Ming Chongyan, he should say that he deserved the punishment."

After letting Luo Xiaomei take Xiao Yuehua back to the steward's mansion on their own, Wang Zheng went to the medical school as soon as possible. When the great witch got the news, he hurried over when Wang Zheng walked into the dean's office.

The Great Witch sighed and said, "Of course I know that. At least my medical school reported the properties of the medicine truthfully. Ming Chongyan's medicine is not something rare.

It's just a large dose of poppy fruit juice and sesame seed powder. My medical school and the Imperial Hospital are not without them. In fact, when Your Majesty had a headache before, we used these two medicines in the medicine we used, but in very small quantities."

In fact, Wang Zheng believed that Ming Chongyan died at the hands of Li Zhi.

Wang Zheng nodded, got into the carriage and said no more.

"Ming Chongyan's life or death is not important. Tell me about Ming Chongyan's medicine and the current situation of His Majesty's dragon body."

What Wang Zheng hopes to see is the stable development of the Tang Dynasty. Any turmoil should be avoided as much as possible, not to mention the possibility that Li Zhi will become hysterical.

The Great Witch waved his hand and asked the female disciple who helped her in to leave. Then he sighed and said, "Ming Chongyan's medicine has a strong dependence, and your majesty is not a person with strong self-control, so your majesty is using a very large amount of medicine now."

Some say Ming Chongyan died at the hands of thieves, some say he died at the hands of Li Xian, and some say he died at the hands of Wu Zetian.

After Wang Ping'an's wedding, Wang Zheng continued to stay in Linyuan for half a month, and finally set off back to Chang'an at Xiao Yuehua's urging.

Qibi Ming was stunned for a moment. He did not expect Wang Zheng to ask so directly. As Li Zhi's most trusted person, he naturally knew how Ming Chongyan died. After all, the entire Chang'an City was under Li Zhi's control. It was impossible for such an important person like Ming Chongyan to be killed quietly.

This is a bit difficult to deal with, as drug addicts are capable of doing anything, and the harm that an unrestrained drug addict can cause is simply unimaginable for ordinary people.

There are some things on land that the Tang Dynasty doesn't have. I wonder if you can give me some surprises. I'm afraid my body can't hold out for much longer."

A loud shout interrupted Wang Zheng's thoughts, and then Qibi Ming appeared in front of Wang Zheng. After bowing to Wang Zheng, he said again: "Your Majesty is waiting for the chief steward in the small forbidden garden of Daming Palace."

"Lingnan." Li Zhi sighed and continued, "Speaking of Lingnan, your third son has some new news. He discovered a huge piece of land in the south of the South China Sea. The exact size is still unknown. Anyway, the ship has been circling for two months and has not returned to the starting point.

Li Zhi nodded, opened his eyes and looked at Wang Zheng, pointed at the stone bench opposite and said to Wang Zheng: "Master, please sit down and talk. Is the scenery of Nanzhao beautiful?"

That’s right, if professionals can’t do something, how can a layman possibly do it?

Arriving at the small flower garden, Wang Zheng bowed to Li Zhi, who was resting with his eyes closed, and said, "Your Majesty, how are you?"

Wang Zheng nodded to the witch, and then he and Qibi Ming left the medical school. When Wang Zheng got on the carriage, he asked, "Does the commander-in-chief know the cause of Ming Chongyan's death?"

"Your Majesty, don't you know the properties of the medicine before using it?"

Wang Zheng originally wanted to write a letter back to remind Li Zhi, but after thinking about it, he hesitated. After thinking about it carefully, he felt that he was overthinking it. Given Li Zhi's cunningness, he would not take the medicine unless he had absolute control over its effectiveness.

Given the current level of the Imperial Hospital and the Medical College, and the efforts of so many people for so long, it is impossible that their results would not be as great as those of Ming Chongyan.

Wang Zheng thought about it and felt that what he had discovered should be Australia in the future.

By the time Wang Zheng returned to Chang'an, Ming Chongyan had already died a violent death, and all kinds of rumors were spreading throughout Chang'an.

After all, there has always been communication between the West and the Tang Dynasty. Although things from there are rare in the Tang Dynasty, they do exist. The Medical College and the Imperial Hospital have the full support of Li Zhi. What else can't be obtained?

So after Wang Zhen arranged for his men to continue heading west, he himself set out from the South China Sea and continued to explore southward. It is only natural that he has discovered Australia now.

Wang Zheng thought about it and suggested, "I think we can send more people from the medical school to provide support. This way, we can improve efficiency. After all, no matter what we do locally, it will be much more convenient. At least they can use the materials at will."

Li Zhi nodded and said, "What the steward said makes sense. This matter is easy to deal with. The steward has been away from Chang'an for so long, and the situation in the court has been somewhat turbulent recently. How about the steward go to the court tomorrow morning to calm the situation?"

Wang Zheng really wanted to go up but didn't know what to do.
