Just when Han Li thought that this rainy weather would continue in the near future, the sun finally hung in the sky again, and the sky cleared.

It had been almost half a month since Han Li discovered the secret of the green liquor, and he had been waiting impatiently for a long time. On the evening of the sunny day, he finally saw the wonder that happened four years ago again, one by one, dots of light, densely packed around the bottle, forming a large ball of light.

As soon as Han Li saw this strange scene, the stone that hung high in his heart finally fell again, and it was basically certain that this vial was not a one-time consumable, but a strange object that could be used repeatedly.

After another seven days of waiting, another drop of green liquor finally appeared in this small bottle, and when Han Li saw the green liquor appearing in the bottle, although he already had a good grasp in his heart, he was still extremely happy, which indicated that he would have a steady stream of rare medicinal materials in the future, and he would never worry about it again.

It is important to know that the preciousness of a medicinal herb is mostly evaluated by its age, and the longer a herb is only its age, the greater its medicinal properties. Similarly, the older the herbs, the more difficult it is to find, and they generally grow in the deep mountains and old forests, cliffs, and do not take some risks, which is something that should not be considered.

Although some pharmacies and doctors will cultivate some medicinal herbs themselves, most of them are commonly used medicinal materials that can be used for a short time, and most people will not be stupid to grow things that can be used for more than ten years or even decades.

But there are also some wealthy and wealthy families in order to prevent accidents, will ask people to plant a few very rare herbs to save their lives in times of crisis, these medicinal materials generally do not have any medicinal effect after a long period of time, because slightly ordinary things, with the net worth of these people can be easily bought, so why bother to cultivate it! And these families can inherit the family wealth from generation to generation, and they don't care about the length of time it takes to cultivate these herbs, and no one knows whether they will be useful one day, so these herbs generally have to spend hundreds of years to cultivate at every turn, or some rare, unique products, ordinary people do not have such financial and material resources to do so.

Occasionally, some rare medicinal materials in the wild are short-lived on the market, and most of them are purchased by these families, which causes the price of rare medicinal herbs to rise in the market, and often has no market.

Han Li wasn't optimistic about the prospect of Doctor Mo's outing this time, and it was estimated that he wouldn't have much to gain, but he didn't have to worry about it now, with this bottle, how many good medicinal materials could be born in a short period of time.

With a strange mood, Han Li did several experiments on ripening herbs in the next dozens of days.

Once, he sprinkled the diluted green liquor on a lot of herbs, but the next day he only got a large number of ordinary medicinal materials that only had a year-to-two effect, far less than the herbs he got the first time, and from this experiment, Han Li faintly comprehended some rules.

In the next experiment, Han Li simply omitted the dilution step and directly dropped the green liquor on a ginseng plant, but when he woke up the next day, Han Li actually got a 100-year-old ginseng plant, which was completely indistinguishable from a wild 100-year-old ginseng. This experiment made Han Li overjoyed, not because he had obtained a rare medicinal herb, but because he had roughly mastered the use of green liquor.

Later, Han Li did several more experiments on the preservation of green liquor, and put the green liquor that had just been taken out of the bottle into various containers, including porcelain bottles, jade bottles, gourds, silver bottles, etc., and found that no matter what kind of container it was, it could not store the green liquor for more than a quarter of an hour, as long as the green liquor was taken out of the mysterious vial, it had to be used up within a quarter of an hour, otherwise it would slowly disappear without a trace on its own. The diluted liquid also has the same characteristics, although it can be stored for a little longer, but as long as it exceeds a certain period of time, only other liquids that remain in the container are infiltrated, and the ingredients of the green liquor still disappear.

After doing a few of these tests, Han Li had completely lost confidence in the preservation of the green liquor in other containers, and it seemed that he could no longer store this mysterious liquid in large quantities, so he had to go for another superimposed medicinal property test.

Han Li dropped a drop of green liquor on a green Sanwu grass plant, turning it into a yellow Sanwu grass with a century-old medicinal properties, and a few days later, he dripped another drop of green liquor on it, and its vintage was actually strengthened for more than a hundred years.

Seeing that this was indeed effective, Han Li kept repeating the same practice for more than two months. Whenever a new green liquor was produced from the vial, he dripped it on the three black grasses, and the three black grasses lived up to expectations, its leaves gradually turned from yellow to yellow-black, and from yellow-black to black, and finally after its leaves became completely black and shiny, it became a rare thousand-year-old three-black grass in the world.

This test was very successful, it seemed that if he had patience, he could continue to increase the year of the Three Black Grasses, but for Han Li, this was completely unnecessary, as long as he knew that this method was indeed feasible, he didn't need these medicinal herbs that were too old now, the medicinal herbs of hundreds of years were enough for him to take for himself.

After this long series of experiments was completed, Han Li could finally take a break and take a good count, and at this time, a lot of time had passed since Doctor Mo descended the mountain.

The current Han Li, holding the thousand-year-old three-black grass in his hand, was lying on the wooden bed in his room, in a daze.

His eyes stared straight at the black herb, as if he was studying it, but as long as there was another person in the room, he could tell from his scattered eyes that his mind was not on the three black herbs at all, but on wandering out of the world, not knowing what he was thinking.

He now completely lost the joy he had when he first got this Sanwu grass, but was thinking about the benefits and dangers that this vial brought to him, and he was planning for his future.

Han Li had seen many examples of "Guilty of Guilt" from the various books in Doctor Mo's house, the bottle in his own hand was a priceless treasure, if outsiders knew that he had such a treasure in his hand, he would definitely not live the next morning, and he would be overwhelmed by all kinds of greedy people who heard the news, just like many of the "Men with Arms" before. People from afar don't say, just take the nearest example, if several masters in this door know the secret of this bottle, they will definitely not let go of themselves, and will try their best to kill people and seize treasures, and they will end up with a bleak end of "treasure snatching and destroying".

"I must not tell anyone about the bottle, and I must be careful to use the bottle in the mountains, because the movement of the light point absorbed by the bottle is too great, and if I am not careful, outsiders will discover the secret. Han Li made up his mind and decided not to say a single word to outsiders.

"However, I am in urgent need of medicinal herbs to cultivate now, and it would be a pity not to use this bottle, so I still have to think of a way to get the best of both worlds. He remembered that he had not made any progress in his cultivation, and he was a little gloomy, no matter how he said that the progress of the cultivation mantra could not be delayed, he was not cultivating for the sake of Doctor Mo's supervision, but he had faintly noticed that some of his changes in recent years were inseparable from the cultivation of this nameless mantra.
