Dear Lingshi

Only then did Lu Yunsheng realize that it was not an easy task to take away the Nine-Curved Glazed Lock.

Lu Yunsheng quickly squatted down to take a look, and found that the appearance of the Nine-curved Glazed Lock was similar to an educational toy on Earth - the Nine-linked Rings.

Lu Yunsheng was delighted to see this, as it aroused his interest. When he was alone in a rented house on Earth, he had nothing to do, so he liked to play with these kinds of things to pass the time, although he had never solved the Nine Rings.

At this time, the last ring of the Nine-bend Glazed Lock is tightly fastened to the iron ring on the stone platform. If you want to take away the Nine-bend Glazed Lock, you must untie this ring. And to untie this ring, you must first untie the previous eight rings in turn. As long as one of the steps is wrong, all the previous efforts will be wasted.

Lu Yunsheng calmed down and studied the Nine-curved Glazed Lock carefully. He also had some understanding of its general principles.

He didn't rush into it.

Instead, he fiddled with the Nine-curved Glazed Lock while deducing the steps to unlock it in his mind.

As a cultivator, Lu Yunsheng's mind is now much clearer than before. He looked at the lock for two hours, and just when the sun was about to set, he finally took action.

I saw his hands flying up and down, and in just a cup of tea, he had untied seven rings in one breath.

Lu Yunsheng wiped the sweat from his forehead, his eyes fixed on the last two rings on the glass lock, and he quickly deduced the unlocking method in his mind.

Another cup of tea passed, and Lu Yunsheng's brows suddenly relaxed and his hands started moving again.

"Untied!"

Lu Yunsheng happily held the lock in his hand and walked to the top of the mountain without stopping.

The Jiaochi Mountain was not as high as Lu Yunsheng had imagined. After walking for a while, Lu Yunsheng saw Song Yi sitting cross-legged on a rock at the top of the mountain.

Lu Yunsheng walked up quickly and bowed respectfully to Song Yi.

"Junior Lu Yunsheng pays homage to Master Song Yi!"

Song Yi looked at the Nine-curved Glazed Lock in Lu Yunsheng's hand, then looked at Lu Yunsheng carefully, and suddenly a gleam of light appeared in his eyes.

"With the cultivation of the eighth level of foundation building, the soul realm has actually reached the soul pill perfection like me."

Song Yi was shocked, but he did not show it. Instead, he smiled and said to Lu Yunsheng, "That's amazing! You are the cultivator who passed these two tests the fastest in the past few decades."

"Thank you for your praise, Senior. I am just lucky. I wonder where the third test you set is?"

"Haha! You are not lucky at all. As for the third test, forget it. I want to ask you a question."

"Senior, please feel free to ask any questions you have."

"Do you want to learn the art of alchemy with me?" Song Yi asked expectantly. After discovering Lu Yunsheng's spiritual realm, he developed a desire to attract talented people.

Hearing this, Lu Yunsheng was very surprised, but he had no interest in alchemy at the moment. He just wanted to run Duobao Pavilion well and earn spirit stones.

After thinking for a while, Lu Yunsheng had to say to Song Yi tactfully: "Senior, I only have a single gold spiritual root, which is not suitable for alchemy."

Hey, this guy is quite interesting. There are so many people in Xianyou City who want to become my disciples, but I was rejected today.

Song Yi was rejected and felt a little uncomfortable, but he still patiently said to Lu Yunsheng: "The requirements for spiritual roots in alchemy are not as strict as rumored. It is not necessary for cultivators with fire and wood spiritual roots to make alchemy. There is no fixed law. For example, if you are a sword cultivator, can other cultivators not use flying swords?"

Song Yi's words shocked Lu Yunsheng. He didn't expect that this old man had such a sharp eye that he could actually tell that he was a sword cultivator. But why did this old man want to take him in as his disciple so much?

Just as Lu Yunsheng was thinking secretly, Song Yi spoke again: "You see, I have the wood spiritual root. Every time I refine the elixir, I still need the help of the ground fire of Jiaochi Mountain. And my master only has the water spiritual root."

Lu Yunsheng nodded when he heard this. Although he had never come into contact with an alchemist when he was in Tieshan City, he still knew some common sense about alchemy, which was that in order to become an alchemist, one must be a cultivator with both fire and wood spiritual roots.

"You see, you find it incredible, that's because you haven't reached that level yet. So I'm going to ask you again, are you willing to be my disciple?"

Hearing this, Lu Yunsheng suddenly felt overwhelmed, and had to say to Song Yi with an apologetic look on his face: "Senior, to be honest, I came here today just to ask you to help me refine a furnace of elixirs."

Song Yi did not continue to persuade him after hearing this, but asked, "What kind of elixir do you want me to refine?"

"Marrow Cleansing Pill. I have already prepared all the necessary materials."

"Oh? A third-level elixir, okay! But I have one more request."

"Senior, please speak up."

"It's not difficult. You just have to watch me while I'm refining the elixir."

"Okay!" Hearing this request, Lu Yunsheng agreed without thinking.

Although Lu Yunsheng knew in his heart that Song Yi's purpose in making this request was to drag him into the trap, Lu Yunsheng only wanted to earn spirit stones and improve his own strength at this time.

As expected, after Lu Yunsheng followed Song Yi to a cave and looked at the alchemy furnace in front of him, Song Yi began to explain it in detail, just like a master teaching his apprentice.

"Now I am still in the Golden Core Stage, and it is more stable to use the Earth Fire to make pills. Some alchemists will choose to use spiritual wood as fuel to make pills. Of course, when I break through the Nascent Soul Stage, I can use the Infant Fire to make pills. In that way, not only will the success rate be improved, but the medicinal power of the pill will also be more refined."

As Song Yi spoke, he gestured to Lu Yunsheng to take out the various spiritual medicines needed to refine the Marrow Cleansing Pill.

Song Yi took the pile of spiritual herbs from Lu Yunsheng, and took out a spiritual herb from the medicine shelf beside him, and explained to Lu Yunsheng: "Look, these spiritual herbs, different years, different growth environments, even if they are the same spiritual herbs, they contain different medicinal properties. The first step in alchemy is to distinguish the medicinal properties of spiritual herbs, which is crucial for the subsequent alchemy.

Upon hearing this, Lu Yunsheng could only nod his head with a vague understanding.

"As a cultivator with wood spiritual roots, I have only taken advantage of the ability to identify medicinal properties. Of course, if you are experienced, you can also use your spiritual sense to identify medicinal properties directly..." Song Yi identified the spiritual medicines prepared by Lu Yunsheng while giving Lu Yunsheng a detailed explanation, which benefited Lu Yunsheng a lot. At the same time, he also roughly understood why Song Yi wanted to accept him as a disciple.

Because the alchemy process places strict requirements on the alchemist's soul power, it is estimated that Song Yi wanted to take him as a disciple only after he discovered his own soul realm.
