The next day, Lu Yuan started preparing for the experiment. His experimental plan was very simple: buy back the medicinal materials according to the secret recipe he remembered, buy a batch of white mice, use the secret recipe on the mice, and observe the effect of the secret recipe on the mice.

However, drugs that are effective for humans may not be effective for mice, but it would be hard for Lu Yuan to find someone to experiment on, let alone experiment directly on himself, right?

Therefore, it is a good choice to use mice to conduct experiments and observations first.

Due to limited financial resources, many of the secret recipes cost a lot of money. Lu Yuan first chose the simplest and cheapest medicinal bath recipe that he remembered for the experiment. He calculated the approximate amount of medicinal materials to be used in the experiment in advance, and then went to the Northern Star.

Buy good medicinal materials at the medicinal materials market.

Lu Yuan did not tell Lu’s parents and Lu’s mother about the experiment, and used his own private money.

He has a lot of private money, some tens of thousands of dollars.

In these years, relying on certain advantages of being a time traveler, Lu Yuan made some money, but most of the money he earned was kept by Lu's parents and Lu's mother, who made him a minor.

But if Lu Yuan needs money, Lu’s parents will not be stingy. For example, if Lu Yuan proposes to exercise and learn boxing... it’s all paid by Lu’s parents.

But for this experiment, Lu Yuan was not going to tell his parents first. It was hard for him to say, "Mom and Dad, I found an awesome ancient recipe. I will buy some Chinese medicinal materials and test them on mice. If it works, our family will

Just posted it.”

If you spend tens of thousands of yuan to buy medicinal materials for a white mouse to soak in, Mom and Dad will most likely think that there is something wrong with the baby's brain!

Lu Yuan could only use his own private money first.

Of course, his private money was also given to him by his parents, and his parents would also ask about it. After all, parents would worry about their children spending money indiscriminately and doing bad things with the money.

Lu Yuan wanted to create an established fact before Lu's parents found out and stopped him.

On Sunday, at Lu Yuan's house, he watched Lu Yuan come back from outside with a large box in his arms.

Hearing the sound of "squeaking" coming from inside, Ma Lu said: "Xiaoyuan, what did you get? No pets are allowed at home!"

Lu Yuan smiled and said: "Mom, this is the white mouse I bought for experiments."

Mother Lu came over and opened the box, looking at the dozens of mice crowded together inside, and said, "Why did you buy so many? What experiment are you going to do? Is it arranged by the school?"

Lu Yuan shook his head and said with a smile: "No, it's an experiment I'm planning to do myself. Alas... you won't understand even if I tell you, so just leave it alone!"

Mother Lu was unhappy and said: "I am your mother, so I can't control it?"

But after hearing what Lu Yuan said, she really didn't ask any more questions.

When the word "experiment" came out of Lu Yuan's mouth, Lu's mother thought it must be linked to learning, and as long as it was beneficial to Lu Yuan's study, although Lu's mother didn't understand, she would support it.

This is also the thought of many Chinese parents.

So when they hear that their children want to buy something for school, they will pay without hesitation, because they feel that as long as it is beneficial to their children's learning, it is worth paying.

Mother Lu asked again: "Do you want money?"

This is asking Lu Yuan if he needs money from them to do this experiment?

Lu Yuan shook his head and said: "No need for now, my pocket money is enough."

Mother Lu nodded and said: "Well, if you need money, tell your mother. Don't spend money randomly and don't learn well..."

Seeing that Lu's mother started nagging again, Lu Yuan quickly said: "I understand, Mom, I won't be a bad learner. Go and cook quickly, I'm already hungry!"

Mother Lu was unhappy and said: "What's the matter? Do you think your mother and I are bored? If you have a daughter-in-law in the future, you will have to dislike me even more?"

Lu Yuan rolled his eyes speechlessly and said: "How could it be possible? You will always be my dear mommy, my great mother... Mother, go and cook. I want to eat scrambled eggs with tomatoes. Don't add tomatoes."

.”

Mother Lu was so happy after being praised by her son, but she said: "Eat, eat, eat, you know how to eat. I don't care about you, I'm going to cook!"

After walking a few steps, Ma Lu reacted, "Tomato scrambled eggs, without tomatoes?"

After coaxing Mother Lu away, Lu Yuan carried the box containing the mice to his room.

The laboratory is his room.

Lu Yuan took out the small retractable collar he bought and attached a number tag on it. Then he caught the mice in the box one by one and put collar numbers on them.

Lu Yuan bought a total of sixty-four white mice. After numbering them, Lu Yuan divided them into four groups, three of which were used for experiments and one for control.

The three groups used in the experiment were medicated baths with different concentrations.

After dividing the mice into groups, Lu Yuan put them into eight cages (Lu Yuan felt that living together in a group of sixteen mice was too crowded, so he bought eight cages).

Lu Yuan did not give the mice a medicated bath immediately because he had to go to school from Monday to Friday, so he specially set the time for giving the mice a medicated bath in the evening.

In this way, even during the school day, he can give the mice medicinal baths at a fixed time after school (the physical states of living things are different at different times of the day).

At 7:30 in the evening, after dinner, Lu Yuan began to give the mice medicinal baths.

He boiled the water and poured it into three large buckets with different colors and numbers "A, B, C". Then he put the medicinal materials prepared in advance into the three buckets according to the calculated dosage, and waited until the water temperature dropped to the point where

When the temperature reached by the mice, pour the three groups of mice into buckets A, B, and C respectively.

After soaking the mice for thirty minutes, everyone picked them up, dried them all with the prepared dry towels, massaged their bodies, and placed them in a wheel-shaped cage.

, let them move, digest and absorb the medicinal power.

Lu Yuan was really worried about these little guinea pigs.

After all the busy work, it was almost eleven o'clock. Lu Yuan put the mice back into their respective cages and fell asleep on the bed.

Lu Yuan woke up early the next morning. The first thing he did after waking up was to run to the mouse cage to observe the conditions of the mice, but he didn't see anything special.

Lu Yuan thought about it and thought it was the same. He had just taken a medicinal bath. If there were any big changes in one night, then the medicine was too strong.

He weighed the feed and put it in the cage. He specially put some more feed for the mice that had taken a medicinal bath last night.

According to Lu Yuan's experience of taking medicinal baths when he was Yuan Changsheng, medicinal baths will improve the quality of the human body, but after the improvement of the human body's quality, sufficient nutrition must be provided to keep up.

The so-called "poor culture and rich military" is exactly like this.

If martial arts practitioners want to exercise well, they must have adequate nutrition.

After putting in the feed and drinking water, Lu Yuan pointed eight surveillance cameras at the eight mouse cages. Today was Monday. He had to go to school. He couldn't observe the mice at home all day, so he had to use the surveillance cameras to record the mice when he was not at home.
