The Northern Song Dynasty returned south, seeking the truth of the Dao.

"Nine-Turn Golden Elixir? What is the Nine-Turn Golden Elixir? Why have I never heard of it before?" Wang Zhenhuan asked, somewhat puzzled, seeing his excited expression.

"It's normal that you haven't heard of it. I'm not entirely sure either whether this thing is the Nine-Turn Golden Elixir. When I was young, I went to Shangqing to study and I happened to see a record of it in an ancient book."

Legend has it that this Nine-Turn Golden Elixir was created by Laozi, one of the incarnations of the Supreme Lord of Morality. It takes nine refinements to form the elixir, hence the name Nine-Turn Golden Elixir,” Ao Shuang explained.

"Nine refinements?" Wang Zhen's eyes widened. "How long would that take?"

"One refinement is a Jiazi, which is sixty years. Nine refinements are five hundred and forty years. After the pill is formed, it undergoes a heavenly tribulation to wash away the last trace of impurity before it can be taken out of the furnace."

Moreover, the method for refining this elixir is said to have been lost in ancient times. I wonder where this black horn came from.” Ao Shuang said, also somewhat puzzled.

"Could it be that he made it himself? Brother, didn't you say he was a figure from the Qin and Han dynasties? That seems to fit the timeline." Wang Zhenhuan held the porcelain bottle with great affection.

"Impossible. The limit of a mortal's lifespan is the Double Armor. Beyond that, one must either ascend to immortality or undergo corpse liberation. Could this Golden Core not be the Nine Revolutions?" Ao Shuang shook her head as she looked at Wang Huanzhen.

"How can we tell the difference?" Wang Zhenhuan asked.

"Each time it's refined, a layer of cloud-like patterns will appear on the pill. This is called pill cloud, and nine cycles means there are nine layers of pill cloud. Why don't you open it and take a look?" Ao Shuang was also itching to try it out.

"Brother, aren't you worried about the medicine losing its efficacy?" Wang Zhenhuan hesitated. Actually, he also wanted to take it out and test it. But it would be such a pity if such a good thing lost its efficacy due to improper handling.

"We'll just take a look for a bit, then put it back. We can seal it with wax later. To be honest, aren't you curious too?" Ao Shuang asked in return.

"In that case, alright then." Wang Zhen hesitated for a moment, then nodded in agreement. He and Ao Shuang huddled together and carefully opened the porcelain bottle, pouring the contents into their palms.

To his surprise, two pills poured out of the porcelain bottle. However, these two pills did not match Ao Shuang's description at all.

The two stared at each other, bewildered. One pill was gold, the other silver. Both had faint cloud patterns appearing on them; the gold pill had two layers of cloud patterns, while the silver pill had only one.

"Why is there a silver one? Brother, do you even know?" Wang Zhenhuan looked at Ao Shuang and asked with a look of disgust.

"Don't rush, don't rush, let me take a good look. After all, I've lived since the Qin and Han dynasties, so I have some knowledge. This golden core shouldn't be a problem, but this silver core..." Ao Shuang wiped his sweat and gestured to Wang Zhen to calm down.

"Hmm, this golden core should undoubtedly be a second-stage golden core. As for this silver core, if I'm not mistaken, it should be used for healing." Ao Shuang turned around, looking carefully.

Upon hearing his words, Wang Huanzhen immediately understood. He realized why the man recognized Qin and Han dynasty seal script and even knew the techniques of the Han dynasty's "Eight Cuts" style. It turned out he was from that era—or rather, a tortoise.

However, beings of other species are different from humans. It may take a thousand years of cultivation for a being of other species to take human form, and everything is just beginning. So a thousand years is a long time for humans, but for beings of other species, especially turtles like Ao Shuang, it may only be one or two tenths of a time.

Wang Zhenhuan put the pill back into the porcelain bottle and put it away. He then asked Ao Shuang, "A second-stage Golden Elixir won't be as effective, will it?"

Upon hearing this, Ao Shuang's eyes widened in shock. He reached out and put his hand on Wang Huanzhen's shoulder, saying, "Brother, that's a golden elixir that's been refined for a full one hundred and twenty years!"

Even at the second stage, it would be considered an elixir of immortality in the mortal realm! You must know that the art of alchemy was lost since the Qin and Han dynasties! Nowadays, Taoists can only refine qi-replenishing pills and wound-healing medicines at most.

You really don't know how lucky you are! This second-stage Golden Elixir might just help you ascend to immortality! Don't give it to me.

Upon hearing his explanation, Wang Zhenhuan immediately understood the function of the golden elixir. Holding the porcelain bottle, he asked with some skepticism, "Brother, do you mean this golden elixir can help one improve their cultivation level?"

"More than that, it not only raises your cultivation level, but it can also instantly replenish your Qi Sea when your spiritual energy is depleted. Just imagine, when you are facing an enemy, your spiritual energy is exhausted, and the enemy is about to kill you."

"Your spiritual energy suddenly became abundant, and you even broke through your cultivation level. What kind of scene is that? It's practically like you were given an extra life!" Ao Shuang patted his shoulder, feeling quite heartbroken that Wang Zhenzhen didn't know what he was talking about.

Hearing Ao Shuang's explanation, Wang Zhenhuan immediately understood the power of the Golden Elixir. And don't forget, there was also a Healing Silver Elixir in the porcelain bottle.

Although I don't know how effective this silver pill is, it can't be too bad to be placed alongside a second-stage golden pill. It must at least have the effect of reviving the dead and restoring flesh to be worthy of being compared with this golden pill, right?

The silver pill healed his wounds, the golden pill helped him break through to a higher realm. Wang Zhenhuan suddenly felt that this small porcelain bottle contained not just pills, but a life! A hope for breaking through to a higher realm in a desperate situation!

"Keep it safe, you'll definitely need it in the future," Ao Shuang said, patting Wang Zhen on the shoulder as he realized what was going on.

"Brother, if you fancy either of these two pills, just say the word. I'll offer them to you with both hands!" Wang Zhenhuan said hastily after regaining his senses. These words were truly from the bottom of his heart.

Without Ao Shuang's invitation, he would never have had this opportunity. Logically speaking, it would be reasonable for Ao Shuang to take half of what was found in the cave.

"You should keep it. Haven't you noticed? The owner of this cave is a high-ranking Daoist named Taiqing. The things he left for you are all related to the Taiqing lineage."

"What does this mean? It means that in your past life you were very likely from the Taiqing lineage! Even if you weren't, you still had a connection with the Taiqing lineage!" Ao Shuang looked at him and said seriously.

Ao Shuang's words were like a wake-up call, instantly enlightening him. Upon careful reflection, he realized that his journey since parting ways with Lin Qingyan seemed to have always been connected to the Taiqing Sect.

Moreover, did Master Xuanyangzi truly pass on the "True Scripture of Primordial Dao Qi" to him because he saw that he had an affinity with the Dao? Or was he instructed by someone else?

Moreover, when he last met Yin Xinghai, he seemed to have foreseen his fate. Now he has come across a cave dwelling, left behind by a Taoist of the Taiqing lineage.

One could be a coincidence, but could both be coincidences? Besides, the owner of this cave already knew of his arrival. He even left three treasures specifically for him.

Thinking about it this way, is the reason he came to the mortal world with some important mission on his shoulders?
