A retired aunt traveled through time and space, and her daughter became rich!

Because the weather was hot, nothing was planted in the greenhouse.

However, after Lin Laoer brought his people to clean up, he saw that the greenhouse was empty anyway, so he planted some seasonal fruits and vegetables.

Aunt Su directed people to plant strawberries and cherry tomatoes, and of course, a lot of peppers were also planted. In addition to these three, Aunt Su also planted some watermelon seeds.

Watermelons already exist in this world, but they are of ordinary variety, with thick skin, many seeds, and not sweet enough.

Even though it is such a poor variety, not many people grow it. In summer, such watermelons cost more than ten cents per pound, and poor families still cannot afford it.

If you can grow juicy, sweet, seed-less and thin-skinned watermelons in winter, needless to say, you can make a lot of money.

But Aunt Su didn't intend to make any money from doing this.

If I could grow enough, I would eat some of it myself and give some of it as gifts to others.

She is not short of money now. Not to mention that she can make money by selling seeds, even if she sells one or two of the gifts she received, it will be enough for her to live for a year.

In fact, if you count the wealthy families nowadays, they can easily earn a thousand or eight hundred taels by selling any decent old items.

But these families have many people and many prodigals! You are a loser, and he is a loser too. It won't take a few days for all your money to be gone.

She is nothing like Aunt Su, who only needs enough money for herself and to pay her servants’ salaries.

On the third evening, Aunt Su got the test results.

Aunt Su looked at the report data in the camera and felt her eyes a little dizzy.

"Heiya, just tell me directly, what is this water like? Can I drink it? I feel dizzy and dizzy when I read these small words. You know I have presbyopia!"

Su Juanjuan smiled helplessly.

"There are indeed many types of minerals in this water. The ones with higher concentrations are probably metasilicic acid, calcium, potassium, sodium, and sulfur..."

"So this water is very suitable for hot springs, and it is very good for the skin, it can kill bacteria and reduce inflammation, and soften the skin... but it is not suitable for drinking."

Aunt Su nodded and said, "That's right. When I went to hot springs before, I rarely heard of people drinking the water directly."

Even if you want to use it right away, it must be processed first. How can you use it directly after it cools down like here?

"What would happen if someone drank it?"

Su Juanjuan smiled, "Mom, I did check it out. The harmful ingredients in this water are not high. Drinking it once or twice should be fine. But if you drink too much, you will suffer from chronic poisoning, such as nausea and vomiting, loss of appetite, diarrhea and abdominal pain, lack of certain trace elements, and stones..."

Aunt Su looked bitter when she heard this.

"Hey, when I first got here, I had a meal made with hot spring water!"

No wonder she felt something was wrong at the time and didn't eat much.

Fortunately, intuition can keep us safe!

"It's just one meal, so it really shouldn't matter. Just don't use it in the future."

Aunt Su pondered for a moment and said, "People around here have been drinking this kind of water for years. I guess there is no other source of water."

Only then did she remember that the old couple who looked after the farm had said that the original owner was an extremely stingy person with bad luck. He lost money in business, and the children in the family were always sick. Their lives were getting worse day by day, so they finally had to sell the farm.

It can't be that the original owner had bad luck because of this, and the children in the family are always sick, right?

"Then can't this hot spring water be processed and turned into drinking water?"

She had money to buy water from other places, and this hot spring villa was just her temporary residence to escape the summer heat and winter cold, and she would not live there for long.

When the weather gets a little cooler, she will return to Su's residence in the capital.

But what should the people living in this area do?

"We can use this kind of hot spring water, but it costs too much! Although you are the owner of the manor, you can't just install a water purification device for a few people? That would cost much more than just bringing water in from outside!"

After Su Juanjuan finished speaking, she searched for a small water purifier on the Internet and showed it to Aunt Su.

Not to mention that the total price of this water purifier is tens of thousands, just looking at the head, I'm afraid the happiness value of spending it is much higher than that of a drone!

Besides, even if it is transferred, who will operate it and who will repair it if the parts are broken? These are all troublesome problems.

Aunt Su thought about it and gave up the idea.

“Isn’t there a more convenient and economical way?”

"Mom, there is actually a simplest and most direct way, which is to collect rainwater!"

"There are hot springs over there, so the underground water is probably connected, and the composition is not much different. Since this water is not drinkable, the two surrounding villages are the same. Why not build a reservoir on the village and collect some rainwater for use. Moreover, the quality of rainwater is cleaner than most drinking water in ancient times, so in ancient times, it was also called rootless water."

Aunt Su thought about it and felt that this was a possible solution.

Before she could open her mouth, Su Heiya had already sent her a blueprint.

"Mom, in order to let your new village have drinking water as soon as possible, I have helped you find the most labor-saving and economical rainwater well construction plan this time."

Digging a well is not difficult, but collecting the rainwater in the courtyard naturally, storing it in the well, and keeping it as clean as possible requires some technical skills... Of course, this technology exists in the world, but it is not easy to find craftsmen with such ingenuity.

Aunt Su was happy.

"You really are my dear daughter! You've already thought of the next step without me even saying anything!"

Su Heiya is really getting more and more knowledgeable. I can predict it without her even mentioning it.

Wouldn't this save her at least two days of work?

The next day, while Aunt Su had people busy digging a well, she also asked people to inquire about the conditions of several nearby villages.

At this time, the old emperor also felt that the palace was stuffy and wanted to escape the heat in the suburbs of Beijing.

The old emperor is different when he gets old than he was when he was middle-aged.

People pay special attention to their sons, grandsons, daughters, and grandchildren.

So an imperial decree was issued, requiring all his sons, grandsons, daughters and grandchildren, except the crown prince, to accompany him to the imperial summer resort in the north of Beijing.
