Find two glass bottles, fill them with well water, Song Bei put them aside, and handed them to Wu Feng and Fu Hao when they left, this is the so-called nutrient solution he promised the two.

As for the efficacy, Song Bei's use of these well water to water the peonies in the yard has been verified, which is enough to ensure the growth of peonies.

Fu Hao and Wu Feng were sitting in the house, seeing Song Bei busy outside, at first they thought he was preparing items for entertaining the two, and told him not to be too polite, but they saw Song Bei walking into the house with two glass bottles and casually putting them on a shelf at the door.

The two asked Song Bei curiously what he was taking.

"Nutrient solution." Song Bei replied, "When you return to Qi City, just take it with you." ”

"This is the nutrient solution?" The two shouted, "Song Bei, the miraculous nutrient solution you said is contained in such a broken glass bottle, and it looks like tap water, which is too disappointing!" We thought it was such a lofty thing. ”

Song Bei snickered in his heart, isn't this just tap water? It's just that it's not just ordinary water.

Fu Hao and Wu Feng were just joking when they said that, they had seen more of Song Bei's magic, and if he took out another item, how could they underestimate it, even if it was really water, it must be a magical water.

The two looked at each other, nodded their heads, and both pulled out their phones.

After Song Bei knew the intention of the two, he didn't say anything, and directly took out the nutrient solution, of course they couldn't pretend not to understand, "Song Bei, let's say, how much is this nutrient solution?" ”

"It's free." Song Bei waved his hand at the two.

Fill two bottles of well water and ask the two for money, isn't this a bit too black-hearted? Moreover, the tea that Song Bei entertained the two of them also used well water, and when Lao Fu left that day, he also poured a large bucket of well water and took it home.

In other words, the fact that the nutrient solution is well water will be understood as long as the two of them are careful and distinguish it a little.

The nutrient solution is a nutrient solution, and the two of them are willing to spend money to buy it, but if the nutrient solution is well water, the two of them will suffer a loss and be deceived if they spend money to buy it.

Song Bei didn't want to affect the relationship he established with the two because of this little thing. It was the money that the two of them bought twice that helped him get off to a start. Well water is not valuable, so it will be sent.

"No, you have to give money." The two don't want to owe too much favor. Song Bei said that the nutrient solution is amazing, this must be a precious thing, how can it be for nothing?

"As you said just now, these are two bottles of tap water." Song Bei told the truth.

Although Song Bei was sure, the two were still a little skeptical, until Song Bei scooped a bowl of water with a bowl and let the two taste it separately, they believed it.

After knowing that it was indeed well water, the two did not insist anymore.

However, drinking this clear and sweet well water, Fu Hao thought of an idea, so he opened his mouth and said to Song Bei: "Song Bei, you can build a water factory in your village, just produce mineral water and sell it, you will definitely make a lot of money." ”

"It's not appropriate." Song Bei directly rejected Fu Hao's proposal, "Only my family's well water is like this, and the water sources in other places are very ordinary, the same as tap water." ”

"Forget it." Wu Feng also helped Song Bei speak, "Let's keep the good water for ourselves, and we don't lack that money, what are we going to do with the water plant?" ”

The construction of a water plant or something, it was all chatted about during small talk, and it was not in everyone's plan at all, Song Bei had no intention of doing so, of course, no one would take it seriously.

Fu Hao remembered that the purpose of his visit today was to buy a nutrient solution from Song Bei. Although the nutrient solution has now become well water, he doesn't need to buy it, he can take it away directly, he still has to understand the effects of the nutrient solution he imagined.

"Song Bei, your nutrient solution, oh, no, it's well water, how long can it last if you water the flowers once?"

Looking at the glass bottle used to hold well water, Song Bei gestured, "This bottle can be used three times, once every ten days, one-third each time, and a total of one month." At other times, just water normally. ”

"A month." Fu Hao repeated in a low voice, bowed his head and calculated silently, "Song Bei, can you give me three bottles at a time?" ”

After knowing that this was well water, Fu Hao didn't want to mention the matter of buying it again, but he just kept this love in his heart.

"Absolutely." Song Bei happily agreed. If there are as many bottles of water as there are from such wells, not three bottles, even three hundred bottles, three thousand bottles, he can take them out immediately.

"Song Bei, tell me again what the effect of this nutrient solution is." Fu Hao said with some excitement.

Song Bei remembered that he had told Fu Hao about the efficacy of the nutrient solution, and seeing that he seemed to have forgotten his current appearance, he told him again, "That pot of peony and that pot of spider plant, if they are placed together with other flowers and plants, they can rob other flowers and plants of the nutrients they need to grow, causing other flowers and plants to fail to grow, or even degenerate." The nutrient solution can give peonies and spider plants sufficient nutrients for growth, so that they can coexist with other flowers and plants. ”

Fu Hao nodded as he listened, signaling that everything he said to Song Bei was in his mind. After Song Bei finished speaking, he asked him again, "This nutrient solution has been left for a long time, it won't be invalid, right?" ”

"Of course not." Song Bei estimated it and added another period, "You can use it at any time within a year." ”

About the nutrient solution, everything that should be understood is understood, and it is noon, so Song Bei naturally left Fu Hao and Wu Feng to stay and eat.

Since he got Bian Que's medical scriptures, Song Bei went to study carefully whenever he had time, because there were no specific cases for him to practice, so he read more about diet therapy and learned how to use food to regulate the body and get rid of diseases.

"Brother Fu, do you feel cold on your knees lately, as if a fan is blowing?"

Since he was going to cook, Song Bei had to carefully observe Fu Hao and Wu Feng, so as to test whether his diet therapy was effective.

"How do you know?" Fu Hao exclaimed in surprise. He did feel uncomfortable in his knees these days, but it didn't affect his walking, and he was in the car most of the time, so he didn't care, let alone mention it to others.

"I know a little bit about medicine, I can see it." Song Bei explained.

"You can see it just by looking at it?" Fu Hao was even more surprised. He is not an uninformed person, Song Bei can see his illness with only his eyes, what kind of medical skill should this be?

Wu Feng also had a feeling of surprise on the side. He has a good relationship with Fu Hao, Fu Hao has a physical problem, he didn't even tell himself, let alone others. Therefore, Song Bei will definitely not know in advance. In saying this, he really saw it himself.

"Song Bei, you can also help me see if there is anything wrong with my body." Wu Feng suddenly remembered that he also had a little problem that was not known to outsiders, and asked Song Beidi half-asking for help and half-testing Song Beidi.

"Okay." Song Bei agreed.

Because he talked to Fu Hao a lot just now, Song Bei's attention was also more focused on Fu Hao, so he first observed the symptoms of Fu Hao's body. Now that he heard Wu Feng's words, he turned his head to observe him carefully.

It didn't take long, and Song Bei nodded slightly.

"How is it, Song Bei, do I have any questions?" Wu Feng asked a little nervously.

"It's a bit of a problem." Song Bei nodded affirmatively in response......

PS: There has been something going on in the past two days, and it will start to be normal tomorrow.
