Han Li placed over a dozen small jade boxes filled with various powders to the side, waved his hand to activate the Dan furnace formation once more, and then retrieved a Dan medicine, the Wang Xi Dan.

After a moment's contemplation, he waved his hand and threw the Wang Xi Dan into the Dan furnace, once again performing the Reverse Dan incantation.

After a little over half an hour, the Wang Xi Dan also transformed into more than ten different materials, which he similarly placed into jade boxes.

He placed the materials from the two Dan medicines together and began to examine them in detail.

"Eh!"

After a moment, Han Li let out a soft exclamation, a smile appearing on his face.

Comparing the materials of the two Dan medicines, most of them were naturally completely different, but one type of blue crystalline powder, regardless of color or shape, was exactly the same, clearly the same material.

However, the blue crystals in the Wang Xi Dan were significantly more abundant than in the Wu Yun Dan.

Both Dan medicines were useful to him, and although it might not be entirely due to the blue powder, it was definitely closely related.

Han Li gently pinched a bit of the blue powder, smelled it, and then tasted it, carefully discerning it, his brows slowly furrowing.

Since the beginning of his cultivation, he had an inextricable connection with alchemy. Whether it was the various alchemy materials of the Human World or the Spirit World, he knew a little about them, and even had some knowledge of the alchemy materials of other realms. However, he had absolutely no clue about the blue powder before him.

"Perhaps, this thing is unique to the Ling Huan Realm?"

Han Li speculated in his heart, thought for a moment, and suddenly stood up, quickly walking out of the cave dwelling.

It was already dark.

A flash of green light appeared on Han Li's body, and he flew out.

A moment later, he landed in front of a cave dwelling on Luoxia Peak, dozens of miles away.

The location of this cave dwelling was quite remote, with no signs of human habitation nearby.

Han Li looked around, walked to the entrance of the cave dwelling, took out a communication talisman, whispered a few words, and waved his hand.

The communication talisman turned into a white light and flew into the cave dwelling.

A moment later, the gate opened with a rumble.

"Elder Gao, I'm disturbing you." Han Li said, cupping his fists.

"Not at all! Fellow Daoist Han, I didn't expect to see you again so soon, please come in." Gao Bulin walked out with a smile and invited Han Li into the cave dwelling.

Gao Bulin's cave dwelling was noticeably larger than Han Li's, but the furnishings were quite simple, and a strong medicinal fragrance permeated the entire cave dwelling.

"Elder Gao, I'll get straight to the point. I've come here to ask you for some advice." Han Li said directly after sitting down.

"Fellow Daoist Han, please speak freely." Gao Bulin said, taken aback.

Han Li took out the jade box containing the blue powder, handed it over, and said, "Elder Gao is knowledgeable, I wonder if you recognize this thing?"

Gao Bulin ohhed, took the jade box, and examined it carefully, his eyes slightly narrowed.

He reached out and pinched a bit of powder, tasted it on his tongue, and raised his eyebrows slightly, looking at Han Li with a somewhat meaningful gaze.

"It seems that Elder Gao already has an answer." Han Li said with a slight smile.

"Hehe, in this matter, Fellow Daoist Han has asked the right person. But..." Gao Bulin smiled slyly, hinting at something.

Han Li said nothing, directly took out a high-grade spirit stone, and threw it to the other party.

The old man Gao deftly caught the spirit stone, a smile immediately appearing on his face, and continued, "To be honest with you, this is actually the powder of the Yun He Cao, a spirit grass that, after a certain number of years, is one of the main materials for several high-level Dan medicines of this sect, and is quite rare. Moreover, this powder of yours seems to have been processed by other means. Only I, who refine Dan medicines all year round and am familiar with various spiritual materials, can barely recognize it."

"So that's how it is... Can Elder Gao elaborate on the medicinal properties of this Yun He Cao?" Han Li nodded thoughtfully, and then asked.

The old man Gao gave another sly and cunning smile, smiled without saying a word, and rubbed his fingers together twice.

Han Li threw another high-grade spirit stone to the other party.

The old man Gao happily put away the spirit stone, shook his head and swayed, and then slowly said, "This Yun He Cao, also known as the Variegated Grass, presents white for a hundred years, blue for a thousand years, starts to turn red after three thousand years, dark red after ten thousand years, and purplish-red after more than thirty thousand years. The most special thing about this spirit grass is that it can absorb the energy of the morning sun, and after a hundred years, it will give birth to a trace of innate purple Qi. It is not only a necessary item for cultivating several amazing cultivation methods, but it can also be directly transformed into innate spiritual power, which has the effect of washing the marrow and changing the meridians. The longer the age, the more refined this innate purple Qi becomes, and the more amazing the effect."

"Innate purple Qi... I wonder where this grass can be found?" Han Li's heart stirred.

"The growing environment of this grass is very harsh. As far as I know, it can only be found in a few places, and these places are basically under the control of the major sects. Nowadays, those over a thousand years old are almost all in the hands of the major sects, and cannot be seen outside." The old man Gao scratched his head and continued.

After listening to Gao Bulin's words, Han Li basically had a conclusion in his heart. Most likely, it was that trace of innate purple Qi that could restore his magic power.

"Besides the Wang Xi Dan, what other Dan medicines are refined with Yun He Cao?" Han Li thought for a while and asked.

This time, Gao Bulin did not hinder him and replied directly, "In addition to this Dan, a small amount is also used in the Wu Yun Dan. In addition, the Yang Ling Dan and Yuan Xu Dan also use a small amount of low-year Yun He Cao, but the innate purple Qi contained in them is negligible."

After separating from Gao Bulin, Han Li went straight to Tong Yi Valley, spent a top-grade spirit stone, and bought several of each of the Dan medicines he mentioned. He also purchased several hundred-year-old Yun He Cao plants, and then returned to Chuyun Peak.

In the secret room of the cave dwelling.

Han Li sat cross-legged on a futon, with the newly bought Dan medicines and Yun He Cao plants in front of him.

He first opened a white porcelain bottle, poured out a Wu Yun Dan, and swallowed it. A warm current immediately rose from his Dantian, and wisps of spiritual power dissolved from the Dan medicine, gradually transforming into magic power, and storing it.

He was overjoyed, picked up a hundred-year-old Yun He Cao plant, put it in his mouth, chewed it a few times, and swallowed it.

After about the time it takes to drink a cup of tea, his Dantian warmed up again, and wisps of magic power gathered into the Dantian, storing it again.

The corners of Han Li's mouth curled up, revealing a smile. He finally confirmed that this innate purple Qi was indeed the key to restoring his magic power.

After a day and a night, after taking more than half of the Dan medicines and Yun He Cao plants he had bought, his cultivation gradually rose, and he soon recovered to the late Yuanying stage.

Just as he was overjoyed and preparing to swallow all the remaining Dan medicines in one go, his expression froze.

At this moment, the medicinal power that had not been completely transformed in his body finally gradually turned into magic power, and gathered towards the Dantian.

However, his Dantian was like a water tank that was already full of water, and could no longer store half a point of magic power.

He could only watch helplessly as those magic powers lingered in the Dantian for a while, and then dissipated little by little, turning into nothing.

Han Li sighed, knowing that this matter was mostly related to the changes in the Yuanying in his body, and that taking more Dan medicines would probably not help.

And the reason for this could only be clarified after his physical body and divine sense recovered a bit more.

Now that he could not rely on cultivation to improve his magic power, and could only recover to the late Yuanying stage with the help of Dan medicines, the primary problem was how to accelerate the recovery of his physical body and divine sense.

Thinking of this, he couldn't help but feel a headache, gently rubbing his eyebrows with his index finger, and fell into thought.

After a moment, he seemed to suddenly think of something, raised his head, turned his wrist, and took out the guest elder token.

Han Li invested his divine sense into the token, and a map of the Cold Flame Sect's geographical distribution, formed by golden light lines, appeared before his eyes.

His gaze searched on the map for a moment, and finally fell on the three small characters "Cang Jing Ge" marked on Jísheng Peak. (Library)
