By now, he finally understood that the reason why the other party closed his eyes wasn't that he didn't look at all, but that he was using his spiritual sense to sense the medicinal herbs in the alchemy furnace.

Thinking of this, he also activated his spiritual sense and secretly observed the medicinal herbs in the alchemy furnace.

At the same time, some doubts arose in his mind.

Wasn't it said that spiritual sense couldn't penetrate solid objects? Then why could it penetrate this alchemy furnace? Or was it that the alchemy furnace, like the storage bag, had special restrictions?

In fact, Lu Li's guess was pretty close to the truth. The alchemy furnace, just like the storage bag, had restrictions set up when it was made that specifically allowed people's spiritual sense to probe it for the convenience of controlling the fire.

Moreover, alchemy furnaces were also divided into different ranks. The higher the rank of the alchemy furnace, the more evenly the temperature was distributed inside it, and the more various restrictions it had, making it easier to form pills.

At this moment, the Black Pearl Grass in the alchemy furnace was constantly changing and shrinking, and drops of light black medicinal essence were slowly oozing out from its surface.

After about a quarter of an hour, the extraction of the Black Pearl Grass was completed, and a drop of essence the size of a grain of rice lay quietly at the bottom of the alchemy furnace.

"One Jade Red Grass."

Xiao Jue let out a slight sigh of relief and said faintly.

"Yes."

Deng Qingsheng quickly took out a palm-sized emerald red spiritual herb from the jade basin, opened the lid of the furnace, and was just about to throw it in when he suddenly felt a burning pain in his hand. In a panic, he dropped the lid of the furnace to the ground.

At the same time, he threw the Jade Red Grass into the furnace.

Sizzle...

Instantly, the color of the essence of the Black Pearl Grass, which had already been extracted, became a shade lighter.

"Damn it!" Xiao Jue sprang to his feet and scolded harshly, "How many times have I told you? Don't you know how hot this furnace is?"

"I... I forgot..." Deng Qingsheng lowered his head and didn't dare to look at Xiao Jue.

"Forgot? I think you didn't take my words to heart at all. Or is it that I've been too kind to you, making you a bit too conceited?"

"Your disciple knows his mistake." Deng Qingsheng knelt down with a thud.

"Go back to the back mountain and go into seclusion for half a year. Temper that bad temper of yours. Don't think you're so great just because you have three spiritual roots. If you haven't changed after half a year, don't stay on Tianjue Peak anymore. I don't want a disciple like you."

"Master!"

"Hmm?" Xiao Jue raised his eyebrows.

"Yes." Deng Qingsheng stood up with a dejected look. When passing by Lu Li, he gave him a fierce glare, opened the mechanism, and walked out without looking back.

Xiao Jue shook his head, turned off the underground fire, took a look at the dozens of remaining spiritual herbs in the basin, waved his hand to put them away, thought for a moment, took a book from the bookshelf beside him, and handed it to Lu Li, saying,

"This 'Spiritual Herb Treasury' was brought back by the founder of our Qingyang Sect from the upper sect. It records many spiritual herbs and is very precious. I don't ask you to remember the properties of all kinds of medicinal herbs, but you must remember the names and appearances of the first fifty kinds of medicinal herbs within seven days. I will bring medicinal herbs to test you in seven days."

"If you can answer correctly, you can continue to stay. If you can't answer, then you can go back to the Servant Hall. And don't even think about getting the contributions."

Hearing this, Lu Li's face immediately showed joy. He quickly took the "Spiritual Herb Treasury". Compared with the contributions, this was the real treasure. He didn't make any guarantees but just said that he would do his best.

Xiao Jue was in a bad mood and didn't bother to say more nonsense to Lu Li. He directly drove him out.

After coming out of the alchemy room, the oppressive atmosphere disappeared immediately. Lu Li took a deep breath and went back to his own cave dwelling with the "Spiritual Herb Treasury" in his arms.

Whether others could remember the names and appearances of fifty kinds of spiritual herbs within seven days, he didn't know. But he had the Time Hall. Seven days for him was equivalent to seventy days. If he couldn't remember them even with this advantage, he might as well just bang his head against the wall.

Moreover, Lu Li had liked reading books since he was a child. Although he couldn't remember everything he read at a glance, his memory was quite good.

Furthermore, since he opened up his first qi meridian, his ears and eyes had been improved again. He believed that it would be easier for him to memorize books.

In the Time Hall.

Lu Li couldn't wait to open the "Spiritual Herb Treasury". When he opened it, he was even more delighted. There were not only illustrations in it but also descriptions of the growth environment and properties of the medicinal herbs below.

The so-called properties referred to the common effects of the medicinal herbs and which other medicinal herbs they conflicted with.

Stone Orchid Grass, it takes a hundred years to reach the first rank and can grow up to the third rank at most. It prefers shade and fears sunlight. It often grows under stone crevices and is commonly used in refining the first-rank Mighty Strength Pill...

Fire Yang Spirit Leaf, it takes three hundred years to reach the first rank and can grow up to the third rank at most. It prefers sunlight and dislikes shade...

Thorn Algae, it takes a hundred years to reach the first rank and can grow up to the second rank at most. It suits both yin and yang and is amphibious. It is often used to neutralize the properties of medicinal herbs...

...

The more Lu Li read, the more interested he became. After quickly flipping through a few pages, he turned back and started studying from the first page. He not only wanted to remember the names and appearances of the medicinal herbs but also planned to remember all the annotations.

This book was really precious. He was worried that if he missed it, he would never come across it again.

In the evening, Lu Li went out to have something to eat. Just as he was about to leave, the fat cripple in the kitchen suddenly said, "Junior Brother, that Deng Qingsheng came here angrily today and took a big bag of dry food. He was cursing and swearing. He looked extremely angry. You should be careful and find a chance to go back to the Servant Hall."

Deng Qingsheng.

Lu Li turned around, cupped his hands, and said, "Thank you for your kindness, Senior Brother. I'll be careful."

He naturally knew why Deng Qingsheng was angry. However, since the other party was punished to go into seclusion for half a year, he wasn't ready to leave just like that.

"I hope you won't end up like me." Staring at Lu Li's departing back, the fat cripple sighed, sat down at the table, lifted up his trouser leg, and stared at his right foot with a look of helplessness.

It turned out that his right foot from below the knee was actually a wooden prosthetic limb.

After returning to his room, Lu Li immersed himself in studying the "Spiritual Herb Treasury" again.

Suddenly, Lu Li's body trembled. On the twentieth page, he saw something very similar, which looked like a strawberry, bright red all over and surrounded by a faint flame aura.

He quickly took out the prescription for the Piercing Acupoint Pill and compared them. To his surprise, they were ninety percent similar.

Scarlet Flame Fruit, it takes a hundred years to reach the first rank and can grow up to the third rank at most. It belongs to the yang attribute and only grows in magma fire veins...

"So, your name is Scarlet Flame Fruit."

Lu Li firmly remembered this name in his heart. In this way, he had completely mastered the four kinds of medicinal herbs for the Piercing Acupoint Pill. As soon as he had some means to protect his life, he would leave the Qingyang Sect and go to look for these spiritual herbs.

That Deng Qingsheng didn't seem to be much older than him. What did he rely on to order him around? Wasn't it the cultivation level corresponding to his age? If he was strong enough himself, why would he need to be so subservient?

If he was strong enough, how dare Deng Qingsheng talk to him like that!

After remembering the Scarlet Flame Fruit, Lu Li continued to turn the pages.

Time flew by. In the blink of an eye, six days had passed since the last time they refined pills.

On the seventh day, Lu Li put away the "Spiritual Herb Treasury" after just reading it for half a day because up to now, he had already remembered all 6,301 kinds of spiritual herbs recorded in this book.

Including their properties and growth environments.

It took him more than two months in the Time Hall. This speed wasn't very fast, but Lu Li was already quite satisfied.

He wasn't a genius and didn't have the ability to remember everything at a glance. He just read a bit more.

Ding! Ding! Ding! Ding!

Lu Li was just about to go out to relax when the bell on the roof suddenly rang. It seemed that Elder Xiao was looking for him.
