Ye Qingtao realized that with Gu Xiu'an's physical condition, he would definitely not be able to finish ten laps.

He was already struggling by the time he reached the eighth lap.

"Xiu An, stop after you finish this lap."

Ye Qingtao couldn't bear it, so she took the initiative to reduce his distance by two laps.

Gu Xiu'an shook his head stubbornly. He couldn't speak, but he kept persisting.

Finally, he managed to finish the last two laps.

This was the first time Ye Qingtao saw such a determined look in a child.

From this incident, Ye Qingtao realized a problem.

Gu Xiu'an is a very stubborn person. Once an arrangement is made for him, he will accomplish it no matter what.

Even if we wanted to give him a reduction in the middle, he would not agree.

Therefore, subsequent training for him needs to be proposed in a moderate manner based on his abilities.

After running the 10th lap, Gu Xiu'an immediately lay down on the ground, opening his mouth and exhaling deeply.

"Xiu An, stand up. You can't lie down immediately after strenuous exercise. You can stand here and rest for a while. When the situation gets better, you can sit down slowly."

Ye Qingtao guided him to change step by step, and Gu Xiu'an was a person who listened to advice.

In order to get better quickly, Ye Qingtao did whatever he said.

He struggled to get up from the ground and forced himself to stand up.

At this time, he just felt dizzy and might fall down at any time.

Ye Qingtao helped him stand under a tree so that Gu Xiu'an could hold onto the trunk and rest.

His face was very pale at first, and it took him a long rest before he gradually recovered.

"Drink some water, it will make your throat feel better."

Ye Qingtao handed over the thermos cup, which contained the medicinal tea she had brewed in advance.

It can regulate the body and moisten the throat.

Gu Xiu'an took it and took a sip, and indeed he felt much better.

He looked at Ye Qingtao with gratitude and smiled, then took a few more sips.

After running 10 laps, his energy was completely exhausted. His legs were shaking and completely out of control, but now they were slowly beginning to recover.

Gu Xiu'an looked at the dark brown liquid in the thermos in surprise.

He originally thought that the medicine would be very bitter. After all, the smell was so strong that it must have contained a lot of medicinal herbs.

After drinking it, it actually tastes sweet, and it has the effect of promoting salivation and quenching thirst, as well as restoring physical strength.

Gu Xiu'an stood and rested for more than ten minutes, and only sat down slowly after he felt much better.

Now he had no intention of lying down.

Ye Qingtao sat with him until his complexion returned to normal, then went home with him.

Ye Qingtao boiled a large pot of water and prepared some medicine. After Gu Xiu'an finished his exercise and his pores were fully dilated, he needed to take a bath.

This way the medicine can be absorbed faster and is more beneficial to his body.

While Gu Xiu'an was taking a bath, Ye Qingtao took this opportunity to go back to her room to calculate the formula.

She had read a document before, which talked about a very magical medicine called Chenggusan.

This kind of powder had been developed by someone before and had been mass-produced, but he was the only one who had the prescription.

Later, someone coveted his prescription and killed him.

By chance, Ye Qingtao got half of the prescription for Chenggu San.

Half of the prescriptions are of no use to the average person.

For the other half of the medicinal materials, you need to guess and then prepare the medicine based on its medicinal properties.

Even if you find all the right herbs, the dosage of each herb is still a very troublesome problem.

Chenggusan has miraculous effects, especially for gunshot wounds and trauma.

Once there is a foreign object in the body, it can usually only be removed by external force or surgery.

If you have bone-strengthening powder, you can sprinkle the powder on the injured area. The powder will work and directly stretch the wound open.

If the bullets, arrows, etc. are not stuck deep, they can be easily taken out.

This can work wonders whether it is used by troops or on the battlefield.

Ye Qingtao has always wanted to make the bone-strengthening powder.

It certainly wasn't easy to develop such a magical drug at that time.

Otherwise, this drug would not have completely disappeared until today.

Many people wanted to replicate it, but failed in the end.

Ye Qingtao is one of these people. She has been researching this drug for more than ten years and had already had some ideas about it before she traveled through the book.

After traveling through the book, although she was developing other medicines, she also took time to think about the formula of Zhenggu San.

Ye Qingtao has made several versions and used them for experiments, but the results were somewhat insufficient.

She kept thinking, what exactly is the problem?

She sat down and seemed to be in a daze, but in fact she had entered a state of meditation.

She had been thinking about it for more than half an hour, but still hadn't made any progress.

The current version developed can be used, but the effect is not perfect.

Ye Qingtao is a perfectionist, so naturally she couldn't accept it.

What she wants is perfection, and every medicine developed by her can exert its efficacy perfectly.

She couldn't accept this little flaw.

Ye Qingtao sat there thinking for another half an hour, until she heard some noise coming from the bathroom, and then she woke up from her dream.

The moment Ye Qingtao stood up, an idea flashed in his mind.

It suddenly occurred to her what the problem was with the drug.

The noise in the bathroom was getting louder and louder. It seemed that the water had become cold. Gu Xiu'an was struggling to get up.

Ye Qingtao quickly wrote down her inspiration on paper and ran to add hot water to Gu Xiu'an.

As expected, Gu Xiu'an prepared to get up and heat up the water himself because the water was cold.

When Ye Qingtao went over, he was naked, holding a ladle, ready to scoop hot water into the bathtub.

"Xiu An, put it down quickly. I'll get you some hot water."

Ye Qingtao took a bath towel and draped it over his shoulders, then quickly went to the kitchen to scoop a bucket of hot water and add it in.

The cold water instantly became warm. Ye Qingtao stirred the bathtub with her hands, making sure the water temperature was right, and then hurriedly urged Gu Xiu'an to continue taking a bath.

Gu Xiu'an jumped back into the bathtub. Just as Ye Qingtao was about to sit down, a loud phone ring suddenly rang in the living room.

Since Ye Qingtao moved here, she hasn't answered any external calls for a long time.

Now the phone suddenly rang, and she was still a little surprised.

Ye Qingtao walked to the phone and quickly answered the call.

"Hello, who are you looking for?"

Ye Qingtao's voice sounded a little mechanical; after all, she was still in a hurry to calculate the formula.

If a phone call suddenly came now, she wouldn't want to answer it unless she found it too noisy.

While Ye Qingtao was answering the phone, her mind was working rapidly as she thought about the details she had just recorded.

If the bone-climbing powder is fully developed according to this ratio, the effect should be very good, right?
