In the early morning of the second day, Chen Yu told Sun Buer that he would send food directly to the valley in the future, and he didn't have to wait for him, so he turned around and returned to the valley with an early start. After breakfast, he began his day's cultivation.

The fourth layer of mantras, he has been vaguely feeling that he is about to break through for the past month. But no matter how he cultivated, he couldn't break through the barrier of window paper on the fourth layer.

......

Just after noon, Chen Yu finished today's cultivation. He was determined to go to Ebi's bookstore and practice dispensing. Although he is now well-versed in medical books, and even familiar with the properties and functions of various medicinal materials, and is well versed in pharmacology, it is always good to try it himself.

What Chen Yu wants to configure now is the Imperial Injury Scatter, which is slightly inferior to the Imperial Soul San. Relatively speaking, the cost of Yusan is low, medicinal materials are common, and although the effect is not as domineering as that of Yulingsan, it is the most commonly used to treat external injuries, but the former will leave scars.

The main ingredients of the two flavors of Yu Ling San are 200 years old because they require 200 years of medicinal materials, so ordinary people still can't afford to use them. If it weren't for the fact that Hai Lao's medicinal materials in the previous year were exhausted, Chen Yu would rather allocate some Imperial Spirit Powder, after all, it was for himself.

Chen Yu hadn't thought about the medicinal materials in the Hai Lao Medicine Garden, but they were just some small seedlings. Chen Yu walked out of the door and walked towards Hai Lao's room. It was midday, and the sun was a little hot outside.

"Huh..... No, there's a place in the west where the sun is so dazzling. Chen Yu's figure was stunned, just now when he went out, he felt a dazzling light in the direction of the medicine garden. I just thought about things and didn't react.

He turned and looked at the medicine garden to the west. I saw a silvery grass in the medicine garden, swaying in the breeze. Chen Yu rubbed his eyes, unable to believe what he was seeing, he quickly ran towards the medicine garden.

Chen Yu looked at the half-foot-tall silver grass in front of him in a daze, with a total of eight leaves, and he couldn't help but step forward and touch its leaves. There's some hardness and a bit of a metallic feel to it. Chen Yu was a little dizzy, this is the silver grass that is being used for eight hundred years.

Silver grass grows a leaf every hundred years, and the leaves of silver grass over five hundred years old are completely silvery-white. And it is one of the main materials of Yuling San, and it can also be used as a medicine guide for many other medicines, and it is quite versatile.

Chen Yu remembered that the seeds that Hai Lao had planted just before he left, how could a mature silver grass suddenly appear, and the other medicinal herbs next to this silver grass were also a little taller than the others. Chen Yu thought about it carefully, and yesterday he seemed to have poured the remaining dilution on the medicine garden.

"Could it be because these herbs have absorbed liquid?" Chen Yu wondered.

He opened the gourd, only to see that less than a third of the milky liquid was left. Chen Yu picked an astragalus flower, which is the main ingredient of Yu Lingsan's second taste. He drops two drops of milky liquid into the roots. If his conjecture is correct, then tomorrow he will have the two main ingredients of the Imperial Spiritual San, and he will be able to try to configure the Imperial Spiritual Powder.

Thinking of this, Chen Yu felt an inexplicable excitement. If his guess is correct, he will henceforth not lack the precious medicinal herbs of the previous vintage. You must know that in this world, medicinal herbs are also very expensive. At least, Chen Yu can use the gourd to give birth to a large number of medicinal materials, and then resell them to rich businessmen and magnates, and it is difficult to make money if he doesn't want to.

Of course, everything will have to wait until tomorrow. There is also a need for further verification of whether the medicinal materials that have been spawned can be used. However, the two rabbits died, and Chen Yu had no choice but to ask Sun Buji to bring another one. But in order to avoid suspicion from the other party, you have to find a good excuse.

In the evening, Chen Yu arrived at the valley mouth early, and Sun Buer saw Chen Yu standing at the valley mouth, and hurriedly ran over, but he carried two rabbits in his hand. Chen Yu looked at Sun Buerqiang, who was sweating profusely, and couldn't help laughing.

"Senior brother, the younger brother will send the meal over, and he is not lazy on the road...... "Sun Buji gasped and said a little aggrieved.

"Hah.... Don't be afraid. It's okay, I had something else to do with you, but I was worried that you were gone, so I came a little earlier. But why did you bring two more rabbits?" Chen Yu's words changed, leading directly to his ultimate goal.

"Back to Senior Brother, the granddaughter of the kitchen steward was just sent back yesterday. No one wants these two rabbits anymore, and the steward is going to die, and he won't give me any money after buying the rabbits. Now stuff the rabbit directly into me and let me dispose of it. The younger brother was planning to sell them after the meal was delivered. Sun Bu21510 said.

"Alright, stay with the rabbit, and I'll give you the silver. A few days ago, the two rabbits were lonely, so leave them a companion. Chen Yu simply found a reason, originally he was going to fool the other party to help get one or two more rabbits, but he didn't expect to directly meet the ready-made.

"Since the senior brother wants it, the younger brother will let it go. As for the silver, the senior brother gave him enough to buy dozens of rabbits a few days ago, how dare the younger brother ask for silver. Sun Buer hurriedly excused himself.

Chen Yu thought about it, he really didn't have any silver on him. Hai Lao didn't tell him that he still had silver to get every month, and he was stunned for a moment the last time Sun Buji said it. But he didn't need silver in the deep valley, and he couldn't find where to get it. In the spirit that more is better than less, he thought about it or forget it.

Sun Buer looked at Chen Yu, who was silent in front of him, and left with a witty farewell, Chen Yu turned around and returned to the valley with rabbits and food.

......

Early in the morning of the second day, Chen Yu didn't care about freshening up, so he put on his clothes and ran towards the medicine garden. As soon as he left the house, he smelled a faint scent of flowers. Gu was not shocked, Chen Yu had already confirmed the guess in his heart, the liquid in the gourd did have the function of giving birth to medicinal herbs.

Thinking of this, Chen Yu felt a little painful. He wasted the liquid of the two gourds only to find out that if he used the two gourds at once, he would now have a lot of medicinal herbs from the previous year.

Chen Yu stared at the one-foot-tall astragalus flower in front of him, this is a medicinal material that is at least three thousand years old, because the astragalus flower will only bloom after two thousand years, and it will bear seeds in three thousand years. The flowers in front of me are blooming brilliantly and have begun to bear seeds.

Chen Yu suppressed his excitement and went back to the house to get the bamboo tools for digging the medicinal herbs, this is to prevent the iron tools from hurting the roots of the medicinal herbs, and all the medicinal materials of the previous year must be packed in wooden boxes of the previous year to delay the loss of medicinal properties.

Fortunately, there is no shortage of Yao Lao here, and of course these are all learned from medical books and the teaching of Yao Lao.

For a whole day, Chen Yu stayed in the room, and finally configured dozens of packs of Yuling Powder near evening, and the two main plants were consumed. Fortunately, there are still many auxiliary medicinal materials in Hai Laocun.

In order to see if the medicinal herbs that were ripe could be used, Chen Yu tied the legs of a rabbit. He thought about it, and in order to avoid the recurrence of the explosion and facilitate the cleanup, he still separated the front legs of the rabbit with a knife in the yard.

A trace of blood oozed from the rabbit's leg, staining the snow-white fur red. The rabbit looked like it was in pain as it lay on the table, and its body writhed wildly. Chen Yu immediately scattered the imperial spirits that had been prepared long ago, and the rabbit's frantic writhing body stopped.

Chen Yu let go of the rope, put the rabbit into a separate cage, and turned around to go back to the house to cultivate.

......

The next day, Chen Yu was surprised when he looked at the rabbit jumping in front of him. Its injured front leg has recovered and appears to have been uninjured at all, except for blood stains on its leg that confirm that it was indeed injured.

With this time, Chen Yu began to cultivate during the day, hiding the gourd in the grass at night to collect light spots, waiting for it to produce liquid and the medicinal materials needed for growth.

And Chen Yu is determined to keep the gourd his biggest secret. Such an item, if anyone knew about it, would inevitably bring him death. Pifu is not guilty, and he still understands the truth of his guilt.
