I don’t know what Li Er sold in the gourd, but Zhang Yi clearly remembered that Li Er ended the locust plague that swept the world by issuing a self-criticized edict and eating locusts raw.

When I came, I rode my horse like flying, but when I left, I was silent.

Sun Simiao leaned against the carriage with a sluggish face, and the boss opened his eyes, which seemed deeper in the blurry night and dusk. However, Zhang Yi kept thinking about the possibility of carpet-style chickens and ducks being stocked. In the end, he still felt that Li Er was likely to be able to collect some chickens and ducks, but he could only guarantee some important grain production areas, and as for other places, he was powerless.

Both of them were silent. During the silence, the shaft of the carriage hit the ground and the bang sounded particularly obvious, and even the spring breeze on the windows on the road became even more bizarre.

"The county thinks your majesty is sure?" Suddenly, Sun Simiao's speech broke the silence.

When Zhang Yi asked this question, he felt that this old man who usually looks stupid is not as stupid as he imagined. He can continue to think deeply about the rationality of things after getting an emperor with confidence and a positive answer. He is definitely not a character who can fool him casually.

Even if he was fooled by himself, it seems that he was just not touching it.

Zhang Yi sighed and asked back, "So the Taoist priest thinks His Majesty is sure?"

Looking at Sun Simiao, who was also lonely but unable to speak, Zhang Yi had to say: "I believe that tens of thousands or even hundreds of thousands of chickens and ducks are not difficult for Your Majesty. But how much land is there just in Guanzhong? The Taoist priest travels around the world, probably already knowing it? Since it cannot guarantee that all land can avoid locust plagues, I feel that Your Majesty is likely to be able to ensure the highest grain production places."

"What about other places?" Sun Simiao blurted out.

Maybe he also found it ridiculous after he finished speaking. Isn’t the answer obvious? Other places are naturally not the place to protect this locust plague. It should, maybe, maybe... it will be selectively forgotten by Li Er and even the officials in the court.

This is a very cruel answer. At least Sun Simiao couldn't accept it. After continuing to remain silent for a long time, he asked Zhang Yi: "Are you just watching other places beating up by locusts?"

Zhang Yi immediately raised respect for Sun Simiao when he could speak the word "英语". It is said that the ancients compared locusts to gods, or the messengers of the gods on earth. Being able to speak like this at least proves that Sun Simiao had no favoritism or even dislike of locusts. From this point of view, as a Taoist sect, completely denying the divine locusts is not something that ordinary people can do.

Zhang Yi thrust his face and asked, "What should I do with the Taoist priest? Not to mention that we are two of us, even His Majesty can only abandon the army to protect the commander. Without pesticides, even if we want to break our heads, we cannot save the people from water and fire, right? As I said, what we have to do now is to go back to the village quickly, collect more chickens and ducks while the time is early, and save our medicinal fields first. God knows what it will look like after the disaster!"

After a major disaster, there will be a major epidemic, which is a common example.

The so-called groups that the people are most resistant to disasters are often the only ones who encounter natural disasters, saying that their wives and children are separated and their families are destroyed is not a joke. Just like the drought in the first year of Zhenguan, there are countless people who starve to death in the entire Guanzhong area. The so-called tragedy of changing children and eating is almost every day.

But what afterwards?

There are piles of dead people, with dry bones as firewood, and many villages have even become homeless places. The living people leave, no one is buried, the dead bodies are smelly, rotten... Then the water source is polluted, and then there is even more tragic infection.

It is hard to imagine the scene after the locust plague. When facing the upcoming disaster, Zhang Yi felt that it would be better to be a quiet noble. As long as Zhangjiazhuang is fine, the other things should be solved by the great and wise His Majesty Li Er. As long as Zhangjiazhuang is fine, even if it is a small amount of production reduction, as long as there is a medicinal field, he will be the winner of this locust plague and can raise a huge amount of medicinal materials for the Tang Dynasty. With this point, he is a qualified patriotic nobleman and the kind who stands closely with the Tang Dynasty.

However, Sun Simiao fell into deep thought and asked: "What exactly are the pesticides you are talking about? Can it cure locusts?"

After understanding his own situation, Zhang Yi's mood immediately improved and explained to Sun Simiao: "This pesticide is actually a medicine. I just want you to treat people's diseases. For example, the tideworms, I believe that you have the final say in this. Many people need to take a small amount of arsenic every few years, and use the arsenic medicine to kill and excrete these parasites growing in the human body, thereby achieving the goal of human health.

The same is true for pesticides. They use drugs to kill pests in the fields without destroying the growth of plants to ensure the normal growth of crops. However, this seems to be not a little bit of this thing in our Tang Dynasty. I am just thinking about it. If you really want to make this thing happen, it is not a little bit of trouble!”

"It's very troublesome?" Sun Simiao continued to ask.

"Of course it's very troublesome! Let me tell you, first we need to know what medicine to use to poison locusts. This requires a large number of drugs to be tested, and the things involved are not something that two people can do." Zhang Yi thought for a while and continued: "Take medicinal materials as an example, there are no less than a thousand well-known drugs alone, and they must be matched. Even if you know very well about drugs and can rule out a large number of unsuitable drugs, there are probably many left, right?

Even if you find the right combination day by day, you still need to test the dose. You need to test how much medicine can ensure that those locusts are killed by the medicine, and you must also test whether these drugs are harmful to people and how harmful... Do you think you can complete so many tests?

Besides, even if you have finished all the previous steps, you will find so many medicinal materials and people to make this pesticide for you? In order to be portable and used, you have to make it into a medicine and concentrate it... Are you talking about it simple?”

It feels very fulfilling to say things that others don’t know, especially when he said in front of a famous person like Sun Simiao, he felt as comfortable as sleeping in the clouds.
