How did a bastard like him become an immortal?

Back at the Water Curtain Cave, Li Muyun immediately sat down to regulate his breathing. The Overbearing Triple Transformation could greatly increase Li Muyun's cultivation and allow him to challenge opponents of higher levels. However, this secret technique also placed a huge burden on his meridians. If he did not carefully recuperate and regulate his breathing after using it, it was very likely to damage his foundation.

"You little brat, you always make me clean up your messes!"

The long-eared fairy floated out, rolled its eyes helplessly, and casually set up a small energy-gathering array. This array could absorb life essence to help those inside heal and recover.

A smile crept onto Li Muyun's lips, a warm feeling washing over him.

When Li Muyun first met Long-Eared Immortal, he appeared as a cold and aloof immortal. However, after spending so much time with him, Li Muyun realized that Rabbit Lord was a warm-hearted person beneath his cold exterior, especially towards him. Although they weren't formally master and disciple, their relationship was as close as that of master and disciple, father and son. He was far better than his so-called father, Li Rentu.

After two hours of cultivation, Li Muyun's internal energy surged once again. Not only were his injuries fully recovered, but his cultivation level also advanced further, reaching the eighth level of Foundation Establishment.

"call!"

Exhaling a breath of stale air, Li Muyun rolled over and stood up, feeling the surging true energy. He smiled confidently, "I'm one step closer to the Golden Core realm!"

The long-eared immortal nodded. "Your performance in today's battle was also quite impressive. Not only were you able to make flexible use of the newly learned Five Elements Talisman Array, but you were also able to integrate your various immortal techniques. Your so-called combination technique, the domineering immortal technique version of the Four Directions Thunder Tribulation Sword, has already begun to take shape as a divine immortal technique."

Scratching his head sheepishly, Li Muyun chuckled, "I just combined these immortal techniques to see if I could unleash even greater power, and I didn't expect it to actually work."

"Immortal arts, immortal arts, the arts of gods, each has its limits, a hundred people, a hundred paths. To develop one's own arts based on the existing ones, that is the way of immortals. To blindly copy other people's arts is ultimately inferior," the long-eared immortal instructed, shaking his head.

Li Muyun nodded as if he understood, "Then if I can learn the immortal techniques of the Three Pure Ones in the future, will it be the same?"

Long-eared Immortal stumbled, then slapped Li Muyun on the head with his backhand. "The Three Pure Ones are Heavenly Dao Saints, representing the Heavenly Dao. Do you want to tamper with the Heavenly Dao? You ask so many questions, but I see you're perfectly fine. Come on, fifteen times the gravity, go cultivate under the waterfall!"

After saying that, he kicked Li Muyun down the waterfall, and fifteen times the force of gravity descended instantly.

"Hiss... Mr. Rabbit, this is settling a personal score!" Li Muyun said, grimacing as he struggled to sit up.

The long-eared fairy grinned and said in a low voice, "Then let's use twenty times the gravity."

......

Three days later.

The young man in white, with a small gourd now at his waist, embarked on his journey to the Blazing Forest.

The Blazing Forest lies a thousand miles deep within the Ten Thousand Demon Mountains, far beyond the outer perimeter where Li Muyun had previously fled. In the depths of the Ten Thousand Demon Mountains, even Golden Core cultivators are not considered demon kings, and Nascent Soul and Divine Transformation cultivators occasionally appear. For Li Muyun, a mere Foundation Establishment Stage 8 cultivator, it is fraught with danger.

Before setting out, he specially crafted a Turtle Breathing Talisman to conceal his aura and avoid provoking violent monsters.

"Rabbit Lord, that Fire Phoenix Bird can occupy the Blazing Forest deep in the Ten Thousand Demon Mountains. It's probably much more difficult to deal with than the Horned Dragon Python, right?"

As Li Muyun cautiously moved forward, he asked somewhat nervously, "It seems like I killed the horned dragon python very easily, but in reality, I used all my strength. If the horned dragon python hadn't just finished its tribulation and hadn't recovered from its injuries, it would have been difficult for Li Muyun to defeat it without paying a price."

If the horned serpents on the outer perimeter are already so difficult to deal with, then the fire phoenixes deep inside must be even more troublesome. What's more, the fire phoenixes are flying demonic beasts, and Li Muyun doesn't have wings. His half-baked sword-flying skills are useless for fighting.

The long-eared immortal snorted disdainfully, "No matter how powerful they are, they are just a bunch of shabby birds in the Golden Core stage. If their ancestor, the Three-Headed Fire Phoenix, were to come in person, I would be a little afraid of them."

"A flock of mixed-breed birds? Why a flock?" Li Muyun sensed something was amiss.

Long-eared Immortal cleared his throat before saying, "Ahem, I didn't tell you this because I was afraid you'd back down. The Fire Phoenix is ​​a gregarious demon beast, and it usually has a demon king, so it might not be so easy for you to deal with it."

Li Muyun sighed helplessly, but his pace didn't slow down at all. "Whether I stick my neck out or not, I'll still get slashed. Can I back down? But even with my Overlord Transformation, I'm no match for those Golden Core demon beasts that live in groups. I can only go and see if I can find any lone ones to ambush and kill."

"Your resolve is firm, and you are a promising young man." The Long-Eared Immortal said slowly and deliberately, "If the time comes, I will take action."

Li Muyun raised an eyebrow and asked obsequiously, "Rabbit Lord, if you were to take action, it would be a piece of cake. Since you're so powerful, how about we go get some high-end stuff, slay a dragon, slaughter a phoenix, or kill a qilin or something?"

Long-eared Immortal remained silent for a long time before finally saying, "I'm wondering how such cold words could come from your honey-smooth, thirty-seven-degree mouth?"

With a laugh, Li Muyun said, "Haha, isn't this what you told me back then, Rabbit Lord? I'm just returning your words verbatim."

"Well done, kid. I see you have extraordinary talent, a prodigy who can single-handedly fight off a flock of fire phoenixes. I'm a bit tired these days and plan to slumber for a few hundred years. You'd better watch yourself," the Long-Eared Immortal said with a sneer.

Li Muyun quickly smiled ingratiatingly, "Hehe, just kidding, just kidding. You are my pillar of strength, my everything. Whatever you say, I will do."

Just as the two were joking and bickering, a majestic mountain range appeared before Li Muyun like a giant beast. Li Muyun took a closer look and gasped. It was actually an ancient city built against the mountain!

The ancient city walls are hundreds of feet high, and horizontally they are like a long knife that divides the Ten Thousand Demon Mountains into two sections. The ancient city walls seem to stretch as far as the eye can see. A huge city gate sits between the two mountains, with an iron-blue plaque on it. On the plaque, three large characters are written in a flamboyant style: "Guardian City".

The magnificent city greatly impressed Li Muyun. Building such a city in the Ten Thousand Demon Mountains was truly a grand undertaking.

"In order to resist the harassment of the demon hordes deep in the Ten Thousand Demon Mountains, the human race spent hundreds of years building the Protector City. The demon race's cultivation level is the same as that of the human race, divided into Foundation Establishment, Golden Core, Nascent Soul, Deity Transformation, Void Refinement, etc. All the great demons above the Deity Transformation realm are blocked outside the Protector City, and the crazy demon tide is also blocked by this Protector City."

"To safeguard the Great Dao of Humanity and protect billions of people—that is the true meaning of this Guardian City's existence."

The long-eared immortal explained its origins to Li Muyun very seriously. Li Muyun nodded deeply. For the rise and fall of the human race, countless human ancestors had to shed blood and sacrifice their lives to build this city.

The Long-Eared Immortal continued, "Now that the Heavenly Dao has turned and the human race is flourishing, this Protector City is mostly used by various sects as a sanctuary for their disciples to go to the depths of the Ten Thousand Demon Mountains for trials."

As the two talked, they arrived at the majestic city gate of [Guardian City]. However, a look of surprise flashed in Li Muyun's eyes. He didn't expect to see a "familiar face" here!
