Years: Salted fish life since going to the countryside.

Chapter 1589 On the Way: Review and Reflection
The sound, though only for a brief moment, was clearly suppressed or lowered by its owner after it came from the bathroom.

However, these few brief sounds still elicited knowing, understanding smiles from the passengers in first class.

Unlike some people who become energetic and restless upon hearing such a sound, Han Li simply smiled faintly, closed his eyes, and focused his mind on the vast Peach Blossom Spring.

The vast Peach Blossom Paradise has changed dramatically since Han Li acquired the soil, water, stone, and sea creatures that Anita Koch of the High T Brothers Law Firm had purchased.

After this period of transformation, those Tai Sui have successfully completed their task of expanding the territory of the vast Peach Blossom Spring.

The current situation in the vast Peach Blossom Spring is that the mountain peak on one side has changed from about 280 meters in length, width and height to about 300 meters in height and more than 500 meters in width and height.

The red pines, pine trees, and purple linden trees that were originally crowded after being transplanted to the mountainside, as well as various valuable fruit trees, shrubs, wild vegetables, wild grasses, and fungi, have now become sparse.

In this way, more trees and plants can be transplanted onto the mountain, and the number of small animals that rely on the leaves, twigs, and fruits of the plants can also be increased.

This is a virtuous cycle, as the numbers of animals such as pheasants, wild ducks, roe deer, sika deer, and musk deer increase.

The food supply for the ferocious beasts like the lynx, raptors like the gyrfalcon and peregrine falcon in the vast Peach Blossom Paradise will increase, and Han Li will then increase their breeding numbers even further.

Now, apart from those that have been eaten by wild beasts and birds of prey, there are 79 pheasants, 63 wild ducks, 86 grouse, 11 sika deer, and 9 musk deer in the vast Peach Blossom Paradise.

This is only because Han Li has been controlling it; otherwise, they wouldn't even have this many left.

Chinese honeybees have almost no natural enemies here, and their numbers have increased from three hives initially to five, and now to eight.

After Han Li released six small monkeys that could move freely into the hive last time, they came over out of curiosity and caused trouble once. After being stung all over their bodies, they dared not approach the hive again.

By the way, the most miserable creature living in the vast Peach Blossom Paradise right now is still that "free-range chicken".

Previously, lynxes, peregrine falcons, gyrfalcons, and even ravens and crows could bully it.

After the six monkeys came in, the "free-range chicken's" life became even worse. Now, it spends most of its time with the little brown horse on the black soil.
-
After the transformation by the Earth Deity, the fertile black soil at the foot of the mountain increased from more than three mu to a little over ten mu but less than eleven mu.

The little brown horse, along with the seven large and two small nine Sugolan highland cattle that Han Li usually left over from eating, are frolicking on this expanded land.

Upon seeing this, Han Li immediately transplanted some of the existing pasture grass from the black soil to the newly added black soil. Before long, the land would be completely covered with pasture grass.

The only thing left undisturbed was the acre of black soil that Han Li had fenced off specifically for growing ginseng.

Haohan Peach Garden currently has a century-old ginseng plant and eighty ginseng roots that are about six years old (originally they were three years old).

There are also more than 200 ginseng plants that have naturally multiplied from the original ginseng plants, which are about one or two years old.

After the transformation of the Earth God, the spring on the mountain peak has become much larger, with a stronger and more abundant flow of water. The stream on the mountain has also widened considerably, and it now resembles a small ditch.

The small pond at the foot of the mountain, near the black soil, that used to be a little over one or two acres, has now expanded to more than five acres.

The increased water supply has made the snow frogs, mandarin crayfish, old manfish, mandarin catfish, bulltail fish, gudgeon, and yellow catfish in the streams and ponds more active.

Perhaps the Tai Sui that was introduced this time was not the kind that undergoes secondary development, so the swamps, low hills, and yellow sandy lands next to the pond in the vast Peach Blossom Paradise remained largely unchanged.

The swamp was still over a hundred square meters, and while loaches and eels scurried in and out, they also had to dodge attacks from gyrfalcons, peregrine falcons, ravens, crows, owls, and wild ducks.

The low hill next to the swamp is still intact, covered with shrubs, wild fruits, and wild grasses. It can be said to be the main habitat of pheasants and wild ducks in the vast Peach Blossom Spring.

On the other side of the hill, the yellow sandy land was still a little over a hundred square meters, less than two hundred square meters. On this land were the tools and utensils that Han Li usually used to process, boil, and age medicinal materials, as well as many cages containing test monkeys. There used to be some glass boxes containing large and small rats here, but after they died of old age, Han Li put all the glass boxes into his decomposition space to save space.

Finally, after the transformation of the sea taisui, the sea level on the other side of the mountain changed from a diameter of more than 300 meters to more than 700 meters.

The sea depth still gradually increases from shallow to deep, with the deepest part reaching over sixty meters.

The main marine organisms now include brown crabs, lobsters, and haddocks from England, and grouper, red grouper, and mouse grouper from Hong Kong, among others.

With their living space expanded, they have also become more active than before.

After Han Li finished investigating the changes in the vast Peach Blossom Paradise, he turned his attention to the twenty-six test monkeys.

Han Li devised a total of six prescriptions for his children: three for strengthening muscles and bones, called "Strengthening Muscles and Bones Powder," and three for strengthening internal organs, called "Consolidating the Foundation and Nourishing the Vitality Paste."

The cost of these medicines taking effect would have made most people give up long ago; it's only because Han Li is wealthy that he can persevere.

Since it concerned his own child, the medicinal materials required for the prescription that Han Li deduced were scarce and expensive, and the cost of each dose was extremely high.

Very tall? How tall?
To put it simply, the cost of each finished drug, excluding labor costs, is tens of thousands of dollars. That price could currently buy a 100-square-foot house in Hong Kong.

If you factor in the labor involved, it's absolutely priceless.

Because the preparation and decoction of the medicinal materials required for these two prescriptions are extremely difficult, if they were given to an ordinary pharmacist, it would be considered a success if one out of ten were successful. Even if one of them were to succeed by chance, the efficacy of the medicine might not meet Han Li's requirements.

If Han Li hadn't possessed the mental strength to accurately grasp the changes during the drug preparation process, his success rate wouldn't have been so high.

Fortunately, after numerous experiments, screenings, and formula adjustments on mice and rats, the two drugs that remained were quite effective.

At the end of last year, in order to further verify the efficacy of the drug, Han Li replaced the mice and rats originally used for the experiment with monkeys, which are more homologous to humans and more closely related.

Because of the differences in size and weight between laboratory mice and laboratory monkeys, the required dosage of drugs has increased dramatically, which has increased Han Li's investment by nearly twenty times.

However, Han Li was not short of money, and he did all this for his children. Without hesitation, he increased his investment and used the medicine on the monkeys.

Han Li originally divided the twenty-six monkeys into several groups, and every once in a while, they would be fed different amounts of medicine.

This study aims to observe the effects and changes of different drug dosages on the bodies and internal organs of animals, with the ultimate goal of finding the optimal dosage for their respective body weights.

However, medicine is not something that can show results in a short time, and it's not something that can be tested on just over twenty monkeys.

It typically takes about ten years for any new drug on the market to go from research and development to market launch.

Even after passing the research and development stage and entering the clinical trial stage, it still requires 300 to 5,000 experimental cases and 3 to 7 years to determine the efficacy of the drug.

The two prescriptions that Han Li deduced both used relatively stable medicinal materials. The time from verification to confirming the efficacy would not be that long, and it would not be possible to make the medicine in one or two years.

However, Han Li was not in a hurry. His eldest children, Da Ming and Xiao Ming, were only two years old. It was not too late for them to start practicing martial arts after they turned six.

Most importantly, Han Li is not a genius and cannot concoct the kind of medicine that can be used to cleanse the marrow and tendons of infants without any side effects.

After Han Li finished examining the monkeys, he began to wonder if he should find some better test subjects than monkeys, with more direct drug effects, when he was pursuing his doctorate in the United States.
Anyway, some people over there aren't even considered human; their existence has never been recognized by the United States.
