The Hehuan Sect cultivates alchemy; my senior sister helps me refine alchemy throughout the world.

A hundred years from now?

How could Shen Yifei allow his own mother to live for a hundred years in a state of being only a soul and a spirit? That would be worse than killing him!

Besides, given his condition, whether he can live for a hundred years is a big question.

From childhood to now, he has never experienced the feeling of a family reunion, nor has he ever had a proper meal together.

"Mother, I'm going to the underworld to retrieve your soul!"

Youlan gave a bitter smile. "The Underworld is a place where nine out of ten living people will die if they go in. Yifei, your mother is staying in the Spirit Ruins. You can come to see me anytime without having to take any risks for me."

"I have to go." Shen Yifei said without hesitation. "Mother, I am your son. You lost two souls and six spirits for me. It is only right and proper for me to venture into the underworld for you."

Youlan was taken aback, then shook her head: "Yifei, the Underworld is no joke. Although your cultivation is not weak, in that place, if a living person goes in, their soul will be corroded by the Netherworld energy. Although you have the inheritance of the Five Elements Demon God within you, you are made of flesh and blood. Once the Netherworld energy enters your body, the consequences will be unimaginable."

Shen Yifei recalled the old man in hemp clothing's words, "Mother, you asked me if I believe in fate, and I said I'm starting to believe a little now. Someone did a divination for me, and the result was very accurate!"

Youlan seemed to believe in fate. "A person's fate is predetermined by heaven. Sigh, your father just doesn't believe in fate!"

Shen Yifei held Youlan's hand. "That person said I have a benefactor to help me, but this benefactor has her own fate. Once something happens to her, it will be the time of my calamity. Mother, for your sake and for mine, I must go to the underworld!"

Youlan's eyes reddened slightly, and after a long while, she said softly, "Then go. But remember, come back alive. If anything happens to you, my soul and spirit will have no meaning."

Shen Yifei chuckled, "Mother, don't worry. I'm a tough guy, I can always turn bad luck into good. Maybe this trip to the underworld will be an opportunity for me."

After calming Youlan down, Shen Yifei found Di Yuan. Upon hearing that Shen Yifei had actually taken over Lingxu, Di Yuan was not surprised at all.

"Lord Wan Shuo indeed made the right choice. From this day forward, this Spirit Ruins has a true master."

"So what will you do in the future?" Shen Yifei asked.

Di Yuan put away his smile. "Logically speaking, I have already completed my mission, but Lingxu is my root. If I leave here, I will disappear. If you don't mind, I will stay in Wanling Palace and take care of Lingxu for you."

Shen Yifei thought about it and also felt that it was most suitable to let Di Yuan guard the Spirit Ruins. This guy had profound cultivation and was loyal to Wan Shuo, so at least he wouldn't cause any trouble.

The two of them huddled together and studied for a long time, eventually creating a small backdoor for the worlds of Lingxu and the Cauldron of Myriad Things.

The two worked together to set up restrictions and entry/exit procedures. Shen Yifei set the rule that, unless under special circumstances, no one could enter or leave the Spirit Ruins at will.

Having arranged everything, Shen Yifei led the Fire Qilin and Liu Mengli and Hongxiu out of the Myriad Things Cauldron.

Outside is the boundary gate of the Falling Star Sea.

As soon as the group emerged from the cauldron, the old tortoise slowly poked its head out from beneath the surface of the sea, its eyes gleaming with amusement: "Kid, looks like you've captured the Spirit Ruins and found your mother too. This trip has been incredibly lucrative!"

When Shen Yifei saw the old tortoise, he thought to himself, "I was just about to get rid of it, and now you've delivered yourself right to my doorstep."

He patted the tortoise shell with a forced smile: "Senior, that's a bit unfair of you. My mother gave you two souls and six spirits so you could enter the family. Why didn't you explain that to me back then?"

The old tortoise shrank back after being slapped, its beady green eyes darting around before it slowly poked its head out again: "Your mother's matter was something she asked me to keep secret. If I had told you back then, would you still be able to enter the Spirit Ruins in peace to seek your opportunities? You probably would have jumped into the Underworld to save her."

Shen Yifei knew the old tortoise had a point, but he still couldn't help but snort, "And now? My mother's two souls and six spirits are still imprisoned in the underworld?"

"Yes." The old tortoise didn't hide anything. "Her soul is pledged beneath the River of Oblivion in the Underworld, and is being held in custody by the judge of the Underworld. When the hundred-year period is up, if she is still alive, her soul will naturally be returned. If she dies, then her two souls and six spirits will belong to the Underworld."

Shen Yifei sneered, "What right does the Underworld have to interfere with the Spirit Ruins created by Wan Shuo? Why should the Underworld set the price for my mother's life?"

"If anyone's to blame, it's Lord Wan Shuo for signing a contract with the Underworld!"

"What contract? A contract to collect souls as tolls upon entry?"

"Well... well, I'm not quite sure about that."

"Alright, senior, please show me the way. I need to go to the Underworld. The Spirit Ruins are mine now! That contract should be nullified!"

The old tortoise said slowly, "Boy, the Underworld is not like the cultivation world. For a living person to enter is almost certain death. Although you are strong and have the inheritance of Wan Shuo, the Underworld has its own rules. If you force your way in, you probably won't even see your mother's soul before you're already lost."

Seeing that the old tortoise seemed to know a lot, Shen Yifei asked, "Senior, you're telling me all this, so you must know a lot about the Underworld. Tell me, how do I get into the Underworld?"

The old tortoise was silent for a moment, then slowly spoke: "I know, but I advise you..."

It paused, then changed its words, saying, "Your mother's matter, though difficult, is not without room for maneuver. The rules of the underworld are made for those who lack ability. If you truly have the ability, the rules can be changed."

Upon hearing this, Shen Yifei chuckled, "Senior, that's exactly what I've been waiting for. Since you say so, it means you already have a plan. Come, tell me, how do I get to the Underworld?"

The old tortoise nodded. "Between the underworld and the human world lies the River Styx, with the crossing at the Netherworld Beach at the end of the Falling Star Sea. However, it is constantly guarded by underworld soldiers, and any living person who approaches will be burned by underworld fire. I have a Yin Commander here, which will allow you to temporarily travel as a spirit without being detected by the underworld soldiers."

Shen Yifei's eyes lit up. "Senior, you even have Commander Yin?"

"I've had dealings with those old ghosts in the underworld a few times. This Yin Commander is something I saved up years ago, and now I'm giving it to you."

The old tortoise said, opening its mouth and spitting out a palm-sized black token. The token had a hideous ghost face engraved on its surface and the four seal characters "Underworld Passage" engraved on its back.

As soon as Shen Yifei received the token, he could feel a surge of yin energy drilling into his meridians from his fingertips.

The old tortoise added, "Remember this: this token only guarantees entry into the Underworld, but how long you stay depends entirely on your own abilities. The Underworld is fraught with danger, especially the banks of the River of Oblivion, where countless spirits dwell. Be extremely careful. If you manage to come out alive, return this token to me."

"Senior, it is said that the Netherworld's energy can harm not only the physical body but also the soul."

Yes! That's why I advise you not to go!!
