How did a bastard like him become an immortal?

The landscape is desolate and bleak. Looking out, the undulating cliffs resemble a giant black python lying on the ground, separating the border between the Sun Moon Empire and the Great Tang Empire. Even from the air, one can only see a desolate and lifeless landscape.

Li Muyun descended slowly with Xie Xian'er, while the giant blue ox followed behind them with great interest.

It didn't come voluntarily, but it was curious that there might be a Teng Snake lurking within the Ding Si Ming Yin Cliff. It always liked to join in on such excitement.

The Ding Si Ming Yin Cliff is almost a natural barrier, isolating the sun and sky and blocking the two great empires, providing an excellent buffer zone for them. Otherwise, war between the two countries would probably have already broken out.

Li Muyun looked up and saw a gray, misty cliff. Just standing on the edge of the cliff, he could feel the heat and mud.

The air was thick with an unusually heavy, viscous stench of decay, like flammable and sticky grease, making the group feel extremely uncomfortable.

At the bottom of the cliff, a putrid, rusty smell permeated the air, as if many living beings were buried there, their corpses lying exposed in the wilderness, and the stench of decay rising from the open air drifted out in waves.

Apart from the suffocating stench of decay, there was nothing else on Silent Cliff.

There was no rustling of the wind, no chirping of birds, not a single sound that any living thing should make; it was a desolate and utterly silent place.

"There's no mistake, this must be the place."

Li Muyun's expression was resolute, seemingly oblivious to the stench, as he surveyed the cliff face from atop a majestic peak.

Behind him, Xie Xian'er was somewhat stunned, her delicate eyebrows furrowed together, and a gloomy mist drifted around her breath, no longer needing to endure this corrupting influence.

"Let's go down and take a look!"

Li Muyun glanced around briefly, found nothing unusual, and then leaped down the cliff.

Suddenly, in mid-air, his mind and body froze. The heat he had felt earlier intensified, and a chilling heat crept over him.

Li Muyun was startled and his figure hovered in mid-air. This Ding Si Ming Yin Cliff was truly beyond his expectations. The coldness and heat could coexist.

The heat was like a thick, greasy substance, and with each breath it felt as if it were being inhaled into the lungs. After stepping into the Ding Si Ming Yin Cliff, the heat in my body was stirred up, and my heart fire ignited.

But what's even more terrifying is that chilling aura that penetrates straight into the soul.

They were still in mid-air, not yet having stepped into the Ding Si Ming Yin Cliff.

A faint, pale light could be seen reaching certain areas, where the chill was like a million needles, piercing through clothing and instantly penetrating to the bone.

Every breath felt like torture, the cold air seeping into my internal organs through my nostrils, accompanied by a burning heat that drove me crazy and made me incredibly irritable.

This is the Netherworld Fire that terrifies all living beings.

Li Muyun remained suspended in mid-air for a moment, his expression constantly changing. Just as he was about to step down, he finally withdrew his foot.

The large blue ox beside him was completely oblivious, and suddenly charged down the hillside, plunging headfirst into the bottom of the Ding Si Ming Yin Cliff.

The big blue ox was still grumbling, saying that Li Muyun was so slow, even jumping off the cliff was so slow, that he wouldn't be able to get a good spot in his next reincarnation.

My heart skipped a beat, and this feeling was so unpleasant.

The thick fur was like being covered in grease, so oily and sticky that it seemed ready to drip and burst into flames at any moment. In contrast, it felt as if one had inhaled a block of ancient ice, the chill penetrating to the bone and impossible to dispel.

The big blue ox tilted its head and quickly took a few deep breaths, trying its best to suppress the burning sensation in its fur.

But as soon as he inhaled those few breaths, the icy flames ignited directly in his lungs, turning into thousands of cold thorns that pierced his heart and lungs. The pain made his eyes widen, and waves of nerve throbbing made his hooves throb restlessly.

The body was already unbearably hot, and the wild thrashing of its hooves only accelerated the process. In a moment, the entire surface of the blue cowhide was engulfed in flames, with the flames gnawing at the cow's body like maggots clinging to its bones.

The big blue ox could no longer restrain itself, let out a howl, and galloped wildly at the bottom of the Ding Si Ming Yin Cliff.

The more they ran, the bigger the fire grew, the more they screamed in pain, and the louder they screamed, the more cold flames they inhaled, creating a vicious cycle.

Both Li Muyun and Xie Xian'er, who had stopped in mid-air, gasped in shock upon seeing the horrific state of the Great Green Ox.

Luckily, I stopped and didn't jump down rashly, otherwise I would be the one suffering like this.

"Ouch!"

The big blue ox finally discovered the problem. With a long moo, it stomped its brute force on the ground and used the momentum to suddenly rise into the sky, finally crashing out from the bottom of the cliff.

Bang!

A huge fireball crashed into the mountain, bursting into flames, but without scattering a single spark, revealing jet-black hair.

The big blue ox shivered a few times from the cold, but two balls of flame shot out from its nostrils, demonstrating the strange nature of this Netherworld Fire.

"The immortal's serpent is lying in a place pretending to be dead. No wonder it can avoid being investigated. Who can stand this?"

The big blue ox was indignant. Its rash intrusion into the bottom of the cliff had caused it a lot of trouble, and it gave the flying snake a good scolding.

Seeing the Great Blue Ox in such a sorry state, Li Muyun was still shaken.

This dead ox is capable of anything, going up to the sky and down to the earth. Relying on its indestructible iron bones, it especially likes to venture into dangerous places. However, even it finds it hard to endure this Ding Si Ming Yin Cliff.

The cold, blazing flames scorch the body and burn the soul. While their destructive power may not be strong, their torment is far superior.

"That's troublesome. This Ding Si Ming Yin Cliff isn't actually gray; it's a yellowish-brown color. The reason it's gray now is because it's covered by layers of Yin Fire, making it difficult to enter."

Li Muyun's eyes flickered with a mixture of yin and yang, and he could already see the thousands of floating, drifting gray flames that had turned this land, which should have been brownish-yellow, into a desolate gray.

Even the thick-skinned oxen could hardly endure it. If they tried their best to suppress their energy, they probably wouldn't be able to go far from the bottom of this cliff.

Then take out the Emperor Flame Blazing Sword to protect yourself?

That won't work either. The Emperor Flame Blazing Sword is the most domineering. If it sees other fire types, it will definitely not restrain itself and will only start a great battle. How can it win against so many Yin Fires?

The two men and the ox were on the cliff, looking very troubled. The blood of the Teng Snake was a very important item, and they had to get it no matter what.

They finally found out where Tengshe was hiding, but unexpectedly, they were troubled by how to enter the Ding Si Ming Yin Cliff.

Xie Xian'er's face turned deathly pale. Her fingertips floated and drifted as she grabbed the swirling Yin Fire in the air. Upon closer inspection, it was covered in fine downy hairs that could scatter and explode at any moment, making it extremely difficult to defend against.

Faced with this strange yin fire, although it was scorching and cold, it was also mixed with scorching heat, which was very annoying.

For a moment, the two men and the ox were at a loss. Even the big blue ox couldn't come up with a good way to control this kind of yin fire.
