Just as Han Li thought this kind of rainy weather would last, the sun finally hung in the sky again and the sky cleared up.

Almost half a month after Han Li discovered the secret of green liquid, he was tired of waiting. On a sunny evening, he finally saw the wonder that had happened four years earlier, a spot of light, dense and numb surrounding the bottle, forming a large group of light.

When Han Li saw this wonder, the tall, hanging stone in his heart finally fell down again, which is basically certain that the vial is not a disposable consumable, but a reusable wonder.

After seven days of waiting, another drop of green liquid finally appeared in the vial. When Han Li saw the green liquid appearing in the bottle, his heart was already 89 points sure, but he was still very happy, indicating that he would have a constant flow of rare medicines in the future, and he would never be sad about it again.

Knowing that much of the preciousness of a medicinal product depends on its age, the longer a herb is only its age, the more potent it becomes. Likewise, the older the medicine is, the harder it is to find, and it usually grows on old mountain forests, cliffs, without taking risks, which is something to think about and not to think about.

Although some pharmacies and doctors themselves now specialize in the cultivation of some herbs, these are mostly commonly used medicines that can be used in very short ages, and most people are not foolish enough to grow something that has been available for more than a decade or even decades.

But there are also large, rich and noble families who, in case of prevention, will ask people to plant a few very rare herbs to save their lives in times of crisis. These medicines will generally not have any effect after quite some years, because something slightly more ordinary can be easily bought by these people's homes, why do you need to take this great effort to specially cultivate them! And these families can inherit family wealth for generations, and they don't care how long it takes to cultivate these herbs. Nobody knows if they will be useful on that day, so these herbs typically take centuries to cultivate, or some rare, unprecedented, lonely item, and ordinary people don't have the financial and material resources to do this.

Occasionally, some wild rare medicines appear on the market and are mostly bought by these families, which leads to the price of rare herbs climbing on the market and often being priceless.

Han Li did not like Dr. Mu's prospect of going out this time. He is not expected to have much to gain, but he doesn't have to worry about it anymore. With this bottle, a lot of good medicine can be produced in a short time.

Han Li was in a different mood, and over the next few decades, several more trials of cooking herbs were conducted.

One time, diluted green liquid was sprayed on many herbs, and the next day only a large amount of ordinary medicines with only one or two years of potency effect was obtained, far less than the first herbs obtained. From this experiment, Han Li Xian's understanding reached some laws.

In the next experiment, Han Li simply omitted this step of dilution and dropped the green liquid directly on a ginseng. Then, the next day, Han Li woke up with a century-old ginseng and a wild century-old ginseng that was completely indistinguishable. This experiment surprised Han Li, not because he got a rare medicine, but because he had probably mastered how to use green liquid.

Han Li then carried out several more green liquid storage tests, put the green liquid just taken out of the bottle into various containers, including porcelain bottle, jade bottle, gourd, silver bottle, etc., and found that no container can store the green liquid for more than a minute. As long as the green liquid is removed from the mysterious vial, it must be used within a minute, otherwise it will disappear without a trace. The diluted liquid also has the same characteristics, although it can be placed for a little longer, as long as after a certain period of time only the other liquids that have penetrated remain in the container, the composition of the green liquid disappears.

After several such tests, Han Li completely lost confidence in the preservation of the green liquid in other containers and seemed unable to store this mysterious liquid in large quantities, so he had to do another superimposed drug test.

Han Li dripped a drop of green liquid on a green sage and turned it into a century-old yellow sage. A few days later, he dripped a drop of green liquid on it, and its vintage actually strengthened for more than a hundred years.

Seeing that it was indeed effective, Han stood for more than two months and repeated the same practice so constantly. Whenever a new green liquid comes out of the vial, he drips it on top of the three squid grasses, which are less than expected. Its leaves gradually change from yellow to yellow to black, and then from yellow to black. Finally, after its leaves become completely black and bright, it becomes one of the rare millennium squid grasses in the world.

This test was a success, and it looks like it could still raise the year of Sanwok if he had patience, but for Han Li, it is completely unnecessary to do so, as long as he knows that this practice is actually feasible, he does not need medicines for these years too long, and hundreds of years of ingredients of herbs are enough for him to take.

After the completion of this long series of experiments, Han Li can finally relax and take a good break and sum it up. At this time, a long time has passed since Dr. Mu went down the mountain.

Now Han Li, holding the millennium three squid grass in his hand, is lying on a wooden bed in his room, stunned.

He stared straight at the black herb and seemed to be studying it, but as long as there was someone else in the house, he could see from his scattered eyes, his mind was not placed on the strain of three squid grasses at all, but outside of Shinto heaven, he didn't know what to think.

Instead of having the pleasure of just getting this sauerkraut, he is thinking carefully about the benefits and dangers this vial brings to him and is planning his way back.

Han Li saw a number of examples of "perfect sin” from various books in Dr. Mu's house. This bottle in his own hand is a priceless treasure. If the outsiders knew that he had such a treasure in his hand, he would never survive the next morning. He would be inundated by all kinds of greedy people who had been heard of, like many of the previous "perfect people". Far from saying, for example, if several doorman in this door knew the secret of this bottle, they would never let go of themselves, would try to kill and seize treasure, and they would end up in a desolate state of "treasure taking away”.

“Never tell anyone about the bottle yourself. Use the bottle carefully in the mountains. The bottle absorbs too much light and the secrets are accidentally discovered.” Han Li decided to keep his mouth shut and not reveal a word to outsiders.

“However, it would be a shame not to use this bottle now that I am in desperate need of medicine training, but to think of a perfectly beautiful solution.” He remembered his incapacitated cultivation and was somewhat obscure. In any case, the progress of cultivating the mantra could not be delayed. Instead of cultivating it for Dr. Murray's scrutiny, he had implicitly perceived that some of his unusual human changes in recent years were inseparable from this anonymous cultivation.
