Zhu Yuanzhang observed Zhang Yi, and when he saw himself, he didn't show any unhappy expression on his face because of what happened last time.

He sighed in his heart that this child's heart was indeed extraordinary.

Lao Zhu pretended to be calm and said:

"Why, I haven't seen you for more than a month, so I can't come to you?"

"Uncle said it was funny, but you are my meal ticket in Yingtianfu, if you don't come to me, I will starve to death!"

Meal ticket?

Although he didn't know what it was, Lao Zhu could feel that Zhang Yi really didn't take the events of that day to heart, he felt better, and then asked the guards outside to move the boxes in one by one.

This time, Zhu Yuanzhang brought in fifty large boxes for Zhang Yi and placed them in the Taoist temple.

Fifty large boxes still look very shocking.

Zhang Yi also gasped as he watched these boxes being opened one by one.

"Even the quartz sand has been obtained, Uncle Huang, you can do it!"

Zhang Yi made a list for Huang He, but he didn't have hope at all about many things.

The flow of goods and population in Daming is controlled, and it is difficult to get some rare materials, he has not worked hard in Longhu Mountain before, but he just can't get it.

Although the contents of the box in front of me are small, they are full enough.

Zhang Yi's eyes are shining, he is really excited!

This scene fell in Zhu Yuanzhang's eyes, Lao Zhu was slightly proud, if Zhang Yi behaved lightly about anything, he should be careful of this child, since he has something to ask for, he can be used.

Lao Zhu Dao:

"These things, whatever you need to mention, your uncle and I still have some way!"

"Thank you uncle for that, I need a little more garlic!"

"What do you want garlic for?"

Zhu Yuanzhang was very curious, he knew that Zhang Yi had many strange skills, could garlic also be used for alchemy?

Zhang Yi smiled and didn't answer, and Lao Zhu didn't ask anymore.

"Senior brother, you help me make a pot of tea and come in!"

Zhang Yi asked Deng Zhongxiu to command the guards to put these materials away, and took Zhu Biao's father and son to the backyard.

Deng Zhongxiu made tea and filled it for the two, but Zhang Yi drank his boiled water.

There is the content of the secret music, and Lao Zhu has long paid attention to Zhang Yi's small action.

"Why don't you drink tea?"

Zhu Yuanzhang pretended to ask Zhang Yi, and Zhang Yi replied: "I'm still young, I don't drink tea!" ”

"The mountain spring water is obviously very sweet, but you drink boiled water, is there any explanation?"

This is the question that Lao Zhu really wants to ask, Zhang Yi didn't think much about it, and replied directly:

"Because there are worms in the water......"

What he said to Chang, naturally there is no need to hide it from Zhu Yuanzhang, and with his relationship with Zhu Yuanzhang, he can say more.

"The water is so clear, why can't I see insects, could it be that you see something in your dreams?"

Zhang Yi nodded and said:

"I read in the Book of Heaven that there are two countries at war in the future world, one of them destroys the country with invisible insects, and the other country resolves it by boiling water, this method is not metaphysics, but something that can be verified by future generations!"

Zhang Yi will tell a certain event in the future time and space, that period of history, as long as most people who lived in Zhang Yi's previous life are familiar with it, because this event really changed their lives.

Zhu Yuanzhang and Zhu Biao, listening to Zhang Yi tell the story of what happened in China in later generations, they only felt ridiculous.

If it weren't for Zhang Yi's previous experience guarantee, Lao Zhu wouldn't believe a word of his words.

Although Zhang Yi is only a few words, it is also impressive.

"Although the soldiers are not tired of cheating, this is still a villain's trip! I...... It's really contemptuous of this kind of method! ”

Lao Zhu despised this kind of behavior fiercely, although the soldiers were treacherous, using the soldiers to attack with water, fire attack, color lure and other means were common, even if he killed prisoners and slaughtered the city, Lao Zhu could understand it.

Many means, in fact, to put it bluntly, are to deter the enemy, and the ultimate goal is to reduce the cost of attack and domination.

But what Zhang Yi said has definitely broken through the bottom line.

is not to give the people a way to live at all, Lao Zhu, who has been a disaster victim, quickly substituted himself into it, and became more and more angry.

Zhu Biao also nodded on the side, this way of using troops is definitely not a royal army.

The future war between the two countries is a distant thing for Zhu Yuanzhang and Zhu Biao after all, but from Zhang Yi's story, Zhu Yuanzhang feels more and more that drinking boiling water is not simple.

It turns out that the means of destroying the country were dissolved by this simple boiling of water?

Zhu Yuanzhang felt more and more that this matter was amazing.

"Boil water, is it that powerful?"

The emperor couldn't help but ask, and Zhang Yi smiled and said:

"High-end ingredients often only need the purest cooking methods, and many of the methods that work wonders are also mediocre...... Uncle Huang, it's not me bragging, if everyone in the world drinks boiled water, there must be tens of thousands of people who can survive because of it every year! ”

Zhu Yuanzhang and Zhu Biao were moved, if this is really the case, it is a lot?

Zhang Yi knew that Lao Zhu didn't believe it, so he popularized the knowledge of microorganisms, bacteria and viruses a little, and also told him how many diseases would be prevented if he drank boiled water.

At least the diseases associated with polluted water are cholera, dysentery, typhoid, hepatitis and poliomyelitis, some of which were called plagues in ancient times......

"The so-called catastrophe will be followed by a pandemic, and to a large extent, it will be caused by the pollution of water sources......"

Zhu Yuanzhang asked Zhang Yi about this, and he was just asking casually, but after Zhang Yi said the truth, his father and son couldn't sit still.

Plague has always been a difficult problem for successive rulers.

Once a plague occurs in a place, it will take away the lives of a large number of people, in fact, the plague has basically not stopped in this era.

It's just that because of the small population movement, most of them only maintain a relatively small intensity.

When the calamity comes, the people will no longer survive and will begin to flow, and the great plague that will sweep through every province will also begin.

How many people die from the plague every year, no one knows better than Lao Zhu, these people are all people who can make tax contributions to the Ming Dynasty.

The Emperor's eyes were red.

"It's so simple, it turns out that sometimes the solution to the problem is so simple?"

Zhu Biao sighed on the side, he had already begun to think about the prosperity of Daming after the implementation of the boiling water order.

It's just that when he came back to his senses, he found that Zhu Yuanzhang and Zhang Yi were staring at him with a very strange expression.

"Did I say something wrong?"

"Zhang Yi, you ...... you"

Lao Zhu shook his head, Zhu Biao can say this, which means that he still needs to learn a lot.

Zhang Yiyan said and said:

"The people are bitter! Brother Huang was born in a rich family, but he forgot that ordinary people, how easy is it to burn firewood? ”

Zhu Biao's face turned red in an instant, even if he was taught a lesson by his father, he was not even as good as a seven-year-old child?
