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

Shen Yifei sent both himself and the bird into the Cauldron of All Things, taking them out of the Underworld.

After crossing the River Styx, Shen Yifei and Liu Mengli's souls returned to their physical bodies.

As Shen Yifei's soul returned to his body, the feeling of fulfillment—the reunion of body and soul—sent a shiver through him. The vortex in his dantian spun even faster, and there were faint signs of a breakthrough in his cultivation level.

In the Falling Star Sea, the old tortoise seemed to have timed it perfectly, waiting for Shen Yifei at the boundary gate.

Upon seeing Shen Yifei, she breathed a sigh of relief, "Not bad, you managed to come out unharmed..."

Shen Yifei took the Yin Commander out of his pocket and handed it to the old turtle: "Senior, return it to its rightful owner."

The old tortoise caught the token in its mouth, swallowed it, and slowly said, "You brought back your mother's soul?"

"I brought her back, and now I've asked someone to help nurture her soul."

The old tortoise nodded. "Have you ever seen a big rooster in the underworld?"

"Senior, are you talking about Golden Armor? Chicken Master?"

The old tortoise glared with its two small eyes. "What 'Grandpa Chicken'? That bastard can be called 'Grandpa'?"

The old tortoise glared with its beady green eyes: "Where did this lump of coal come from, daring to act so arrogantly in front of this old woman?"

"This old woman? You old bastard, you dare call yourself this old woman?" The crow flapped its wings. "Look at your green feathers, haven't you worn too many green hats?"

The old tortoise was so angry that its neck swelled up: "You...you feathered beast!"

The crow doesn't like being called a feathered beast; that's its rebellious feather!

"Who are you calling a feather...?" The crow was about to take flight.

Fearing it might fight the old tortoise, Shen Yifei quickly covered its mouth and said to the old tortoise, "Senior, my little pet is just a chatterbox, please don't take offense."

When the old tortoise saw that the crow's beak was quite formidable, it knew it was no match for it, so it retracted its head into its shell, looking like it was saying, "I'm not going to stoop to your level."

The crow, not one to back down, broke free from Shen Yifei, stood on the tortoise shell, hopping and jumping, cursing for a full half-incense stick's time. Only when it saw that the other party had completely stopped moving did it reluctantly shut its beak and fly back to Shen Yifei's shoulder.

Shen Yifei sensed that there might be some grudge between the old tortoise and the golden armor, but after being scolded by the crow, the old tortoise never showed its face again.

Helpless, Shen Yifei had no choice but to say goodbye to the old tortoise and return to the Tianyan Sect.

After Shen Yifei had walked away, the old tortoise stretched out its head and muttered, "It seems that someone is really going to turn the world upside down this time. Master, everything is as you wished!"

Upon returning to the Tianyan Sect, Shen Yifei's first task was to refine the Underworld King. Although the guy was completely covered from head to toe, he still groaned and whined the whole way.

His grumbling didn't bother him; the crows outside the alchemy room joined in, constantly criticizing Hades's actions in the underworld.

Shen Yifei used his divine sense to take a look. Although he couldn't see the appearance of the King of the Underworld clearly, he could tell that the King was furious and about to explode.

If this thing gets angry, its blood and qi will be disrupted, which will definitely affect the effect of alchemy. Shen Yifei released the restriction on Hades' mouth.

The moment Hades opened his mouth, he burst into a tirade against Shen Yifei, "Shen Yifei, you bastard! I am the ruler of the Underworld! If you dare to refine me, the Underworld will be thrown into chaos, and you will suffer a terrible death!"

The crow, who had been waiting for this, immediately launched into a tirade: "Bah! You old bastard! You did nothing human in life, and nothing ghostly in death. You feed on ghosts to fill your broken skeleton, and you still have the nerve to call yourself the King of the Underworld? Your death will throw the Three Realms into chaos. Do you think the Three Realms' latrine needs your shit?!"

Hades was stunned for a moment, then roared, "You crows that summon souls in the River of Oblivion, how dare you speak to me?"

Ignoring what Hades said, the crow continued its tirade: "You've been the local tyrant of the underworld for ten thousand years, what kind of shady dealings have you been doing? You feed on ghosts, eating three hundred in one meal! Why do I call back those souls in the River of Oblivion? It's just to bring them back one by one, so they don't all end up in your belly!"

"You're talking fucking nonsense! Who said I ate...?"

Before Hades could finish speaking, the crow interrupted, "You're not only gluttonous, you're also lustful! You keep 588 ghost concubines, each one a beauty snatched from the reincarnation list! They're on their way to be reincarnated, and you intercept them to keep as your concubines. Aren't you shameless?"

Shen Yifei was speechless: My goodness, Hades is quite capable, much stronger than me. I am ranked by month, Hades is ranked by year!

Hades loudly protested, "That...that was their own choice!"

"Voluntary?" The crow cawed loudly, "Voluntary my foot! If you hadn't threatened them with a chance to be reborn into your family, would they have gone with you?"

Shen Yifei, listening from the side, couldn't help but laugh: "Crow, how do you know all this?"

The crow proudly raised its head: "My eyes can see through the yin and yang; I can see right through all the trivial matters of the underworld!"

"Five hundred and eighty-eight ghost concubines, this King of the Underworld is quite capable!" Shen Yifei said with a hint of envy.

"Wow, that's impressive! One in a row..."

"Huh? In one breath? Without pausing?"

"What are you thinking about... take a breath..."

The man and the bird talked, completely disregarding Hades' feelings.

Shen Yifei looked at Hades in the alchemy room and said to Crow, "Alright, Crow, let him rest a bit. If he gets too angry, the pills he refines will be of poor quality."

As Hades listened to Shen Yifei and the crow singing in unison in the alchemy room, his heart sank.

He is the dignified lord of the underworld, ruling over billions of souls. When has he ever suffered such humiliation?

It was bad enough that Shen Yifei pierced his dantian with a sword, but now he's being verbally abused by a bird, and he'll be refined into a pill soon.

However, as the lord of the underworld, although his strength is now diminished and he is indeed somewhat weak in some aspects, his body is still intact. If he wants to refine himself into a pill, he still needs a spark!

The crow cursed for a while longer, then, tired of cursing, it found a tree and rubbed its beak against the branches, muttering, "This gun, you know, needs to be sharpened more and more. This crow's beak, it's all about sharpening!"

Once Hades had his ears cleared, he shifted his target. "Shen Yifei, you can't refine me. I am the Lord of the Underworld, possessing the Undying Body of the Netherworld, impervious to all fires. Forget about it."

Shen Yifei ignored him.

He activated the Netherworld Cold Flame, which enveloped the Underworld King in blue flames, and began refining elixirs.

Hades was initially worried when he saw that the fire was different from what he expected. But when the flames touched him, he felt nothing at all.

The Netherworld Cold Flame is specifically designed to refine divine souls, and Shen Yifei believed it was most suitable for the King of the Underworld.

However, the Netherworld Fire burned for a full day and night, but Hades remained completely silent.

Shen Yifei looked and saw that Hades hadn't changed at all; even his skin hadn't changed color.

Hades laughed heartily, "Shen Yifei, telling you is useless; you can't do anything to me!"

Seeing this, Xinghe said, "Brother, cold fire is yin, and the Underworld King is also yin. Using yin fire to refine a yin body is a thankless task."

Shen Yifei thought about it and realized it made sense. "Then let's use yang fire, pure yang fire, which is especially effective against ghosts and spirits!"

He yelled, "Fire Qilin, come out and breathe fire for me!!"
