"The past is long forgotten. It's nothing much," Mo Wuji said calmly. He was sure the woman in front of him wasn't here because of that trivial matter.

Sure enough, upon hearing Mo Wuji's words, Lin Gu seemed to breathe a sigh of relief and straightened up, saying, "Though it's difficult to say, I can only ask Brother Mo to help me this once."

Mo Wuji didn't respond. He wasn't even acquainted with this Daoist nun, so why should he help her? Even with payment, it wouldn't work. He lacked things that she couldn't provide. He really didn't care for ordinary things.

Lin Gu didn't mind Mo Wuji's attitude and continued, "My Demon Moon Immortal Gate has always had a lukewarm relationship with the Pill Dao Immortal Alliance, so we can't ask for the top Immortal Doctors of the Pill Dao Immortal Alliance to help..."

"Wait," Mo Wuji interrupted Lin Gu. "You should know my identity, right? But I can only regretfully tell you that I haven't been in the Pill Dao Immortal Alliance for long, and I don't know any Immortal Doctors in the Pill Dao Immortal Alliance at all. And the Pill Dao Immortal Alliance is mainly about Pill Dao. Even if I have a high position in the Pill Dao Immortal Alliance, I can't ask for a real Immortal Doctor for you. As far as I know, those top Immortal Doctors have nothing to do with the Pill Dao Immortal Alliance."

Lin Gu bowed again, saying, "I know, but my mother is terminally ill. I only ask Brother Mo to help me once and take a look at my mother's illness. Whatever request you have, as long as I, Lin Gu, can do it, I will definitely do my best."

Mo Wuji said with a somewhat displeased expression, "I'm just an Elder of the Pill Dao Immortal Alliance. When it comes to refining pills, I can refine some basic pills. But when it comes to treating patients, please seek someone else who is more capable. It's not that I don't want to help, but I really don't have the ability."

Mo Wuji himself was somewhat speechless. He really didn't understand why this Daoist nun insisted that he could cure diseases. He had never studied medicine, so how could he cure diseases?

Moreover, Mo Wuji knew that medicine was even broader than Pill Dao. One could even say that Pill Dao was a branch of medicine.

Lin Gu said plaintively, "Brother Mo, you are a Fourth Grade Venerable Pill King. I know that even in the Pill Dao Immortal Alliance, there aren't many Venerable Pill Kings. That's why I've come to beg you."

In fact, there was another reason that Lin Gu didn't say, as she was afraid that Mo Wuji would be displeased if she said it. That was that she had learned that Mo Wuji came from the broken ruins and even went before the Golden Abode. Not only that, but Mo Wuji also brought more than ten cultivators from the Eternal Embrace Immortal Domain out of those ruins.

Lin Gu was very clear that entering those ruins and coming out unscathed was extremely rare, at the very least, they would be seven-star geniuses or above. Those top geniuses all had trump cards in their hands to be able to come out of it. However, Mo Wuji not only came out but also brought so many people out, which was definitely not something those star-level geniuses could compare to.

Of course, the most important thing was that Mo Wuji was a Venerable Pill King, and Venerable Pill Kings were rare beyond rare. She simply didn't believe that a Venerable Pill King had no foundation at all.

If she were to look for top Immortal Doctors, where could she find them? The only ones she could find were Pill Kings. And among the Pill Kings, the most powerful Pill King she had come into contact with was Mo Wuji.

This woman had indeed investigated him, Mo Wuji said calmly, "I am indeed a Pill King, but who told you that Pill Kings can cure diseases? You come from a top sect, and the strong people you can come into contact with are naturally much more powerful than me. Until now, your mother's illness hasn't been cured, so you think I can..."

Mo Wuji paused here, suddenly remembering something. The Lin Gu in front of him came from the Demon Moon Immortal Gate, and the Demon Moon Immortal Gate was in the Six Paths Immortal Domain. According to what Mo Wuji knew, the Six Paths Immortal Domain was a Demon Domain.

Mo Wuji didn't care whether it was a Demon Domain or not, what he cared about was the news he had heard from Dou Hualong back then, that the Demon Domain had a passage directly leading to the Underworld.

And the Soul Condensing Immortal Jade Pond was located between the Demon Domain and the Underworld...

"Whether or not you can save my mother, I must do my best, even if I fail in the end, I will have no regrets..." As she spoke, Lin Gu was about to kneel down.

Mo Wuji raised his hand to stop Lin Gu from kneeling, saying, "Let's go back to the Sharp Corner Immortal Ruins with me first."

"Yes," Lin Gu replied with delight upon hearing Mo Wuji's agreement.

...

The Sharp Corner Immortal Ruins was indeed the most convenient place to travel to and from the Shattered World. The three of them only spent half an hour before they once again walked out of the teleportation tower from the Sharp Corner Immortal Ruins to the Shattered World.

Mo Wuji took out a bottle of pills and handed it to Liu Fan, "This is for you, thank you for guiding the way. You can go about your business now. If you come to my pill shop to buy pills in the future, you'll get a 20% discount."

"Thank you, Elder Mo, Liu Fan takes his leave," Liu Fan excitedly accepted the pills and bowed in thanks.

He didn't look at the pills Mo Wuji gave him, but being able to know a real Elder of the Pill Dao Immortal Alliance was a definite advantage. With just this, he wouldn't suffer too much in the Sharp Corner Immortal Ruins.

After Liu Fan left, Mo Wuji said to Lin Gu, "Come with me to the pill shop and we'll talk in detail."

Lin Gu was naturally overjoyed. As long as Mo Wuji was willing to talk to her, it would be a great success for her.

Mo Wuji's pill shop was located in a convenient area, not far from the teleportation tower. Walking at a leisurely pace, it only took about half an hour.

"Big Brother!" As soon as Mo Wuji walked into the shop, Dou Hualong excitedly stood up. Nearly two years had passed, and Dou Hualong's strength was much more solid than when Mo Wuji had first seen him.

Mo Wuji patted Dou Hualong, "The shop hasn't opened yet, what are you doing sitting in the shop?"

Dou Hualong chuckled, "Although the shop hasn't opened, I'm here to promote it, so that everyone will know our shop's reputation when it opens."

Mo Wuji took out a ring and handed it to Dou Hualong, "This ring is full of pills. Sort them according to their grades, and then prepare for the shop's opening."

"Yes, Big Brother," Dou Hualong excitedly took the ring. He was anxious because he had nothing to do every day and was just sitting in the shop.

"By the way, you can decide the pricing of the pills and how to open the shop yourself. You don't need to ask me," Mo Wuji said, gesturing to Lin Gu behind him, and entered the second floor of the shop's small building.

After Lin Gu sat down, Mo Wuji said solemnly, "Lin Gu, to be honest with you, although I am a Venerable Pill King, I am not proficient in treating diseases. You have indeed come to the wrong person."

Lin Gu quickly stood up, saying anxiously, "I don't know who else to look for. The most powerful Pill King I can find is you, I..."

Even Lin Gu didn't know what to say. Mo Wuji was a rare Venerable Pill King and could come out of the ruins' mist in the Shattered World, so he definitely wasn't simple. More importantly, as she herself had said, the most powerful Pill King she could find was Mo Wuji. In the eyes of ordinary cultivators, Pill Kings were basically equivalent to Immortal Doctors.

Mo Wuji raised his hand to stop Lin Gu's words, "Let me ask you a few questions, do you know about the Soul Condensing Immortal Jade Pond?"

Lin Gu was slightly stunned. Although she didn't quite understand why Mo Wuji wanted to ask about the Soul Condensing Immortal Jade Pond, she nodded, "I know."

"Can you tell me about it?" Mo Wuji's spirits perked up, and his voice became a little more excited.

Sensing the change in Mo Wuji's emotions, Lin Gu's emotions also rose, and she quickly explained, "The Soul Condensing Immortal Jade Pond is in the void between the Six Paths Immortal Domain and the Underworld. The Soul Condensing Immortal Jade Pond can condense souls and primordial spirits, allowing cultivators with physical bodies to be resurrected."

"Is it true?" Mo Wuji almost half-stood up.

Lin Gu nodded, "It's true. The daughter of the Six Paths Immortal Domain's Heavenly Emperor, Gai Feiyan, was severely injured and died. Because the people from the Heavenly Emperor's Palace arrived in time, they preserved Gai Feiyan's physical body. Later, the Demon Domain's Heavenly Emperor used a Ninth Grade Immortal Spiritual Herb, the Underworld Heart Divine Flower, in the Soul Condensing Immortal Jade Pond to recall Gai Feiyan's still-undissipated soul, allowing her soul to be reborn..."

"Wait, you said the Underworld Heart Divine Flower is to recall the undissipated soul, not to let it be reborn?" Mo Wuji immediately grasped the key point.

Although he was desperately trying to save Cen Shuyin, he was still a little uneasy in his heart. He was worried that after Cen Shuyin was resurrected, she would no longer be the same Cen Shuyin. But if it was to recall Cen Shuyin's original soul, which was scattered in the Underworld, that would be a different matter.

"Naturally," Lin Gu said with certainty, "If it were reborn, wouldn't that be a disguised way of allowing another primordial spirit to seize her body?"

"Are there any conditions or restrictions?" Mo Wuji's tone became even more urgent.

Lin Gu nodded, "Yes, generally the time can't be too long. Once it exceeds forty-nine years, even with the Underworld Heart Divine Flower, it would be extremely difficult. If it exceeds a hundred years, it would basically be impossible to recall the soul, unless you have great supernatural powers and can enter the Underworld.

The Underworld is vast beyond compare, divided into countless realms. Whether it's mortals or cultivators, as long as their souls and spirits aren't completely destroyed when they die, their souls will enter the Underworld to seek an opportunity for reincarnation. But this Soul Condensing Immortal Jade Pond isn't so easy to enter..."

Mo Wuji suddenly bowed to Lin Gu, "Lin Gu, a friend of mine fell in the starry sky of the cultivation world. Now her physical body is intact. I hope to enter the Soul Condensing Immortal Jade Pond to find her scattered soul in the Underworld. Please help me, Lin Gu. As long as you are willing to help, whether I can cure your mother's illness or not, I will do my best."

Lin Gu finally understood why Mo Wuji wanted to ask about the Soul Condensing Immortal Jade Pond when she heard Mo Wuji's words, but this matter was also difficult for her to handle. That Soul Condensing Immortal Jade Pond wasn't a place that anyone could enter as they pleased.

Thinking that she was also requesting Mo Wuji's help, Lin Gu gritted her teeth and said, "I can help you enter the Soul Condensing Immortal Jade Pond, but even if you enter the Soul Condensing Immortal Jade Pond, it's useless without the Underworld Heart Divine Flower or a Immortal Spiritual Herb of the same level. Without this level of Immortal Spiritual Herb, you can't make the wandering souls in the Underworld sense the physical body at all. Moreover, the more you use this Underworld Heart Divine Flower, the greater the chance of recalling wandering souls in the Underworld. A single Underworld Heart Divine Flower is a priceless treasure, let alone multiple ones."
