There were only a thousand spirit stones in the storage bag, Lin Feng didn't look at it much, and directly threw it aside, but was very interested in the jade slip that recorded the spirit grass.

Lin Feng couldn't wait to invade his divine sense and check the contents of the jade slip, and it took three hours before Lin Feng collected his divine sense and withdrew from the jade slip, but a satisfied smile appeared on his face.

"This jade slip is really very detailed. Lin Feng nodded and muttered to himself.

"Oh, but why?" asked Ling Kongzi inside him.

"The jade slips that I bought in the store before that recorded the spirit grass only introduced some superficial knowledge, even if I got the true inheritance of Elder Yuanying in the secret realm of the Medicine God Sect, although his jade slips were detailed, the types of spirit grass were not so complete. ”

"The elder of the Medicine God Sect is just a wisp of primordial infant, and it is normal for the master to have memory loss after his fall, and of course he will have reservations about an outsider, after all, you are only his nominal disciple. ”

"Well, that's why I said that this jade slip is even more precious, not only is there a complete variety, but also a very detailed explanation of each spirit grass. Lin Feng smiled slightly, put away the jade slip, got up and walked to the door, and could see the moonlight outside through the crack in the door.

"It's still early, so let's go around and familiarize ourselves with the environment in the medicine garden. Saying that, Lin Feng opened the door and saw the bright moon in the sky, and the silver light sprinkled on the ground, which illuminated the night as if it were day, and compared to the sun, the moonlight appeared softer.

Lin Feng walked through the pieces of spiritual fields, carefully checked the spiritual grass on them, and counted the quantity.

"It's snow mushroom, and the leaves and flowers are white. ”

"This is thorn grass, like grass but not grass, like vine but not vine. ”

"This is a hibiscus fruit, the flowers are like hibiscus, and the leaves are like lotus. ”

......

Lin Feng observed the spirit grass while consolidating the knowledge in the jade slip that he had just memorized.

"Sure enough, it's one hundred and three. Lin Feng stood in the last row, nodded and said.

Lin Feng can be said to have gained a lot tonight, he has a heart for refining medicine, but he has no way to guide him, so he can only buy some jade slips about spirit grass and study them by himself, and then do more spirit grass planting and watering tasks.

And the jade slip given by the man surnamed Liu is far more detailed than the jade bought in the store, and now that the spirit grass is in front of him, under the observation of this one by one, Lin Feng's cognition of the spirit grass can be said to have reached a new level.

"Hey, what is this?" Lin Feng was stunned for a moment, and when he walked back, he suddenly saw a spiritual grass outside the house of the man surnamed Liu, with small paths and fat leaves, no flowers and no fruits.

"Is there anything strange about this?" Ling Kongzi said, he had no involvement in alchemy, so he didn't know much about spirit grass.

"The predecessors didn't know it, but it's no wonder that this spirit grass is called Hua'er Hong, and it only blooms for three days in a year, which is extremely rare, and is often mistaken for an ordinary plant. Lin Feng leaned closer and observed the spirit grass in front of him more closely.

"I see, but why does the surnamed Liu hide it, plus this is a total of one hundred and four kinds of spirit grass. Ling Kongzi said strangely.

"I think it should be the reason why this flower red is relatively rare and valuable, according to the memory of the Medicine God Sect, the flower red only blooms for three days a year, and it must be picked on the third day when the flower is about to be gone, and it can be used in medicine, otherwise the effect of the medicine will be greatly reduced. Lin Feng didn't care about others hiding it.

"Then I don't know what this spirit grass is for. ”

"Hua Erhong is the spiritual material for refining the foundation building period elixir, and it is a high-grade foundation building pill, because it doesn't need to be taken care of, so Senior Brother Liu deliberately hid it from me. Lin Feng said and looked away and went straight back to his room.

In the room of the man surnamed Liu, a dark shadow sat cross-legged, and as Lin Feng left, the open eyes closed again.

After returning to the room, Lin Feng took the pill and settled down.

In the early morning of the next day, as soon as Lin Feng opened the door, the man surnamed Liu also walked out.

"I've seen Senior Brother Liu. Lin Feng said slightly.

"Well, have you ever seen the jade slip I gave?" asked the man surnamed Liu very casually.

"Back to Senior Brother, I've seen it. Lin Feng handed back the jade slip, anyway, he had already extended the content to another jade slip last night.

Rubbing is actually very simple, you only need to use your divine sense to restore the things of one piece of jade slip to another, this method is taught by Ling Kongzi, and ordinary qi cultivators really don't know, and the man surnamed Liu can't imagine that Lin Feng has this hand.

"Well, if there's anything you don't understand, you can bring it up now. The man surnamed Liu asked after taking the jade slip.

"Back to Senior Brother, there is nothing to ask. Lin Feng replied.

"Do you really remember everything?" The man surnamed Liu glanced at Lin Feng, his face began to turn cold again, and his voice continued.

"This taking care of the medicine garden is not a trivial matter, you must not be careless and self-righteous, if you remember a little wrong, the entire spiritual land may be destroyed. ”

"Yes. Disciples must remember that they must not forget what the senior brother said. Lin Feng said yes.

"Since you don't have anything to ask, I'll test you and see if you remember them all. A trace of unhappiness flashed on the face of the man surnamed Liu, and he felt that Lin Feng was holding the big one.

"Please also ask the senior brother to give me advice. ”

"Okay, what is that spirit grass called, and how should it be irrigated?" Senior Brother Liu seemed to point casually.

"Senior Brother Hui, that green lotus seed needs to be watered every morning when the dew is dry. Lin Feng arched his hand

"And what about this one?"

"Senior Brother Hui, this plant is called Blood, and it needs to be watered at three o'clock in the afternoon every day, if there is no sun at three o'clock in the afternoon, only half a spoonful will be poured in. ”

"Okay, what about the one next to it?"

"Senior Brother Hui, the one next to it is a cold yin umbrella, because the yin qi is heavier, it will bloom into a disc shape every three days later, and it will be watered once at that time. ”

"Yes, I didn't expect you to have a good memory, so I'm relieved, but you still have to pay attention to the position and amount when watering, you know?" Senior Brother Liu couldn't help but nod with satisfaction when he saw that Lin Feng had answered well.

The three spirit grasses he ordered just now were all very obscure, and he thought that Lin Feng would not be able to answer any of them, but he didn't expect to answer all of them correctly.

"The disciple must manage it well. ”

"Okay, when I break through to the middle stage of foundation building, there will be another spirit stone to thank you. After saying that, the man surnamed Liu explained a few words, and then turned around and left.

After seeing him leave, Lin Feng returned to his room and sat cross-legged and began to meditate and cultivate.

"Don't say it, it's quite suitable for cultivation. Lin Feng smiled, this is the place where the foundation building cultivators live, and the aura is far more abundant than that of the new disciples, plus in the medicine garden, the aura is even more sufficient, compared to Lin Feng's residence, the aura here is more than two or three times.

The sun rises and sets, the morning sun rises and the sunset recedes, this is three days, but Lin Feng couldn't help frowning.

"It's not okay to go on like this, it's too much of a delay in cultivation. Lin Feng groaned.

It turned out that in the past three days, he watered every day, about four hours, that is, eight hours, the same as going to work, the key is that the watering time is not fixed, some morning, some noon, some evening, and some in the middle of the night, there is no way to calm down.

"Taking care of the medicine garden is like this, could it be that he should be answered, and now he still wants to regret it. Ling Kongzi said.

"That's not alright, I'm just going to find a way to make it easier. Lin Feng thought for a moment, suddenly made a wind in his footsteps, and walked towards the outside of the garden, now there were still two hours before the next watering, so he should be able to go out with confidence.

"What did you think of?" Ling Kongzi asked curiously.

"For the water pipe project, I want to press the water pipe for all the spiritual grass here, so that it will be much more convenient. Lin Feng said, his footsteps did not stop, and he came to a bamboo forest behind him after a while.

"Water pipes?"

"That's our 21st century technology, and I'll know it when I'm done. Saying that, Lin Feng stretched out his hand and patted the storage bag, and five flying swords appeared one after another, which was the complete set of magic weapons obtained in the annual competition.

I saw five black shadows shuttling back and forth in the bamboo forest, and in a moment Bailai fell down with the bamboo.

"Your exorcism skills are really perfect, not bad, not bad. Seeing this, Ling Kongzi praised that the current Lin Feng could fully exert the power of that set of magic weapons.

"Isn't it enough, I'm going to be superb!" Lin Feng's face sank, and the five flying swords passed through the bamboo joints of each bamboo, making the interior connected.

After doing all this, Lin Feng transported the bamboo back to the medicine garden.

"The old man still doesn't understand, what do you want to do with all this bamboo?"

"Don't worry, I'll know when I'm done. Lin Feng smiled, and his figure was busy working on the forty-six spiritual fields that needed to be watered.

After a while, rows of bamboo frames appeared on the spiritual field, some bamboo frames were high, on the top of the spirit grass, some bamboo frames were a little shorter, half high in the spirit grass, and some bamboo frames were close to the ground, next to the roots of the spirit grass, these are of course tailored according to different spirit grasses.

And on each horizontal row of bamboo frames, there are many small holes drilled by flying swords, which are only used for drainage.

"Next up is the water valve. Lin Feng nodded with satisfaction, walked to the spiritual spring, opened forty-six holes in a thick bamboo, connected the forty-six branches, plugged each branch with a bamboo stopper, and finally connected the large bamboo with a bamboo plug to the spiritual spring.

"Is this what it is?" Ling Kongzi seemed to understand a little, but still didn't understand what he meant.

"Well, senior, look. Saying that, Lin Feng pulled out the bamboo plug on a branch, and saw that the spiritual water flowed through the collection, to the branches, and finally to each bamboo on the spiritual field, and flowed out through the bamboo holes, just watering on the spiritual grass.

"I see, this water pipe is really ingenious. Ling Kongzi couldn't help but be a little excited.

"It's a very common craft in our 21st century, and every family has it. Lin Feng didn't feel anything.

"What is your world like, the old man is really more and more curious, how can he make such an ingenious thing. ”

"Don't be curious, I don't know if I can go back. Lin Feng was helpless for a while and returned to the room.

It took half a day to make this water pipe, Lin Feng felt that it was still worth it, after all, the eight hours of work were reduced to only using the switch valve, of course, there is no electronic equipment here, and it cannot be turned on regularly, otherwise Lin Feng doesn't have to care about anything, if Ling Kongzi sees the timing device, he must not worship death.
