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

Shen Yifei found a corner to sit down, ordered a pot of tea, and listened intently to the conversation of the men around him while drinking it.

The men were speaking the local dialect of the Western Regions. Shen Yifei could only understand half of it, but he could roughly make out that they were discussing the Demon Clan's territory.

"Have you heard? The Demon King has gone mad again and killed three important ministers."

"That's right. I don't know what's wrong with the Demon King lately. He kills people all the time."

"I heard that the Demon King went mad while practicing his martial arts and lost his mind, killing anyone he sees."

"That doesn't mean we should kill innocent people indiscriminately."

"Hey, stop talking, or we'll all get into trouble."

While listening to the conversation of the men in the teahouse, Shen Yifei pondered, "Demon King, my own grandfather's temperament has changed drastically, and he's indiscriminately killing important officials... the Demon Clan is probably in chaos."

He finished his tea, paid for it, and got up to leave the teahouse.

His divine sense entered the cauldron and asked Hongxiu, "Sister Hongxiu, how far is the Demon Realm?"

"Young Master, if we travel three more days west, we'll see the border barrier of the Demon Realm. This barrier only allows entry, not exit. Then we can reach the city walls of the Demon Realm. However..."

"But what?"

"The Demon Realm is heavily guarded, and all comings and goings are strictly checked. Although there haven't been any major conflicts between the Demon Race and the Human Race in recent years, human cultivators cannot enter the Demon Race's territory."

Shen Yifei chuckled: "Sister Hongxiu, I'm also half a demon. Even if I'm not pure, I'm still a member of the demon race. Can they stop their own people?"

"Young Master, your bloodline... is a bit mixed... I'm afraid it will be discovered that you have human blood, and in that case, you won't be able to enter."

"This is a troublesome matter. Honey, do you have any ideas?"

Liu Mengli had already heard it, "Master, I'll fight my way in for you, catch your grandparents and uncles, and bleed them dry one by one..."

"If you keep talking nonsense, I'll shut your mouth!"

"Come on, what are you going to use to block me? I'm waiting for you..."

Shen Yifei discovered that Liu Mengli had become somewhat disrespectful since awakening the memories of the Reincarnation Demon God, and it seemed he would have to find time to teach her a lesson.

He didn't have time to deal with Liu Mengli now and went straight to Ye Ling's residence.

"Wife, find a way to help me infiltrate the Demon Realm..."

Ye Ling said calmly, "The demon race uses bloodline stones to test bloodlines. Those stones can sense the purity of demon bloodlines; the purer the bloodline, the brighter the light. You do indeed have the bloodline of the demon royal family, but it's mixed with the aura of humans and the Five Elements Demon Gods, so the bloodline stone's reaction won't be very pure."

"What should we do then? We can't just force our way in, can we?"

Ye glanced at him. "With me here, there's always a way. There's an abandoned ancient battlefield on the border of the Demon Realm called Fallen Soul Plains. There's a hidden spatial rift there that can bypass the city walls and restrictions, allowing you to enter the heart of the Demon Realm directly."

Shen Yifei's eyes lit up. "Wife, you should have said so earlier! I was worried for nothing."

"Don't be too happy yet." Ye Ling's tone changed. "Your problem isn't how to get in, but how to avoid being recognized once you're in. The demon territory is not like the human territory. The people there are extremely sensitive to bloodlines. Although you can conceal your human aura, a highly skilled old guy can see through you at a glance."

After hearing Ye Ling's words, Shen Yifei understood that Ye Ling's use of the term "old guy" was not just empty talk.

Those old monsters of the demon race, aren't they all seasoned veterans who have lived for over ten thousand years?

With my current level of cultivation, if those old monsters really set their sights on me, I won't be able to escape.

"It's alright. Once we get to the Demon Realm, we'll head straight for Crimson Flame Valley, grab the Golden Essence, and then go to the Demon Palace to get a couple of drops of essence blood. We'll just have to avoid those old guys."

"The Fallen Soul Plains are located southeast of the Demon Realm, about two days' journey from here. I crossed that spatial rift once years ago, but so many years have passed, I don't know if it still exists."

"Let's go, we'll see!"

Two days later, at Luohun Plain.

On the desolate plain, all around was deathly silence.

"This place was originally an ancient battlefield." Shen Yifei looked around and saw that the ground was covered with weathered and unrecognizable bones and remains.

Ye Ling stood on a black boulder, closed her eyes to sense for a moment, then opened them. "Follow me."

The two continued their journey deeper into the Fallen Soul Plains. After about an hour, a large patch of black scorched earth suddenly appeared on the ground ahead.

"This is it." Ye Ling pointed to a huge crack in the center of the scorched earth. "The spatial rift is right below this."

Shen Yifei walked to the edge of the crack and looked down. It was pitch black below, and the bottom was unfathomable. He could vaguely sense a faint fluctuation of demonic energy emanating from the depths of the crack.

Ye Ling leaped into the crevice, followed closely by Shen Yifei.

The crack was deep, and it took the two of them a full cup of tea's time to land. Beneath their feet was a narrow underground passage, winding and stretching forward, its destination unknown.

"How long is this passage?" Shen Yifei asked in a low voice.

"I don't know." Ye Ling shook her head. "I only remember that after walking out of this passage, you can see a canyon, which is Black Wind Canyon on the edge of the Demon Realm."

The two walked along the passage for about half an hour, and gradually a glimmer of light appeared ahead. As the light grew brighter, the end of the passage came into view.

Shen Yifei crouched at the entrance of the passage and peered out. His view suddenly opened up, revealing a huge canyon below.

At the bottom of the canyon, some simple buildings can be vaguely seen, resembling a small village of demons.

"How did Black Wind Gorge become like this? I remember this used to be an outpost, garrisoned by thousands of elite soldiers. How did it turn into a village?"

"Go down and see for yourself."

Shen Yifei and Ye Ling quietly landed at the bottom of the canyon.

This small village has only a few dozen households. The roofs are made of black stones, and the doors are dilapidated, making it look extremely poor.

Shen Yifei saw an old demon woman sitting at the door, holding a broken bowl in her hand. The bowl contained some black, gooey stuff that looked like wild vegetable paste.

Her face was covered in wrinkles, she was so thin she was skin and bones, and her eyes were vacant.

"Grandpa, what disaster has struck here?" Shen Yifei asked.

The old woman looked up at him, her eyes vacant. "Hungry...so hungry..."

"Hungry?"

The old woman stopped talking and just stared blankly at the broken bowl in her hand.

The demons from the surrounding houses also came out one after another. They were all skin and bones, with sallow complexions, showing signs of long-term malnutrition.

Ye Ling glanced at everyone's appearance and said coldly, "The Demon Clan's territory is so poor."

"Maybe this place is just poor?"

Ye Ling didn't answer him. Instead, she squatted down, picked up a handful of black soil from the ground, smelled it, and examined the soil carefully. "The land is barren, and the demonic veins are depleted. This land is ruined. If the entire Demon Realm is like this, then the demon race is truly doomed."

Shen Yifei called Hongxiu out, and Hongxiu was very surprised when she saw her.

"Young Master, I have been away from the Demon Realm for hundreds of years. When I was still here, although the Demon Realm was sealed, the demon veins here were abundant, the people were prosperous, and although the Demon King had a fiery temper, he loved his people like his own children. This situation would never have occurred."

Shen Yifei didn't ask anything more. It was obvious that something had happened to his grandfather, whom he had never met!
