Yang Che displayed his cultivation as twelfth-layer Qi Refining.

He sped north, specifically choosing uninhabited, secluded paths, pushing the Dunjxing Shuo’s speed to its limit.

Ten days later.

Yang Che barely rested, and with the insane replenishment of his magical power by Mid-Grade Spirit Stones, he rushed all the way to Yi Country in one go.

Yi Country is located in the extremely cold northern region.

The entire country experiences thousands of miles of ice and snow all year round.

Following Ma Qiucheng's instructions, Yang Che soon arrived at one of Yi Country's most famous dangerous places, the Thousand Snow Caves.

This place, covered in white snow, is located within a deep, secluded canyon, as if cut open by a sharp blade.

Yang Che landed in the valley and found that the bottom of the valley was filled with peculiar snow holes.

Thousand Snow Caves, true to its name.

The surroundings were silent, with almost no other sounds except for the occasional rustling of snow falling from trees and the burrowing sounds of some unknown insects.

“Yang Che, are you sure your Junior Brother won't lie to you?”

Tianxie Ziyin’s cold voice carried a clear hint of teasing.

Yang Che, however, said with great certainty, “I’ve thought about this question many times. I don’t think Junior Brother Ma has any reason to lie to me. After all, he could have chosen whether or not to tell this secret.”

“But, being careful is a must. If there’s danger here, I’ll run immediately.”

Although Yang Che believed Ma Qiucheng wouldn't lie to him, he still maintained an extremely high level of vigilance and caution.

“Mie, Divine Sense.”

Yang Che directly used the Divine Sense of Spirit-Level Ancient Blood Corpse Mie and began to search these thousands of snow caves one by one.

After several passes, it wasn't until Mie showed a languid expression that Yang Che finally pinpointed several snow caves.

“Zi Yin, you really haven’t heard of this strange beast, the ‘Nie Yun Sable’?”

“Never heard of it. But perhaps I’ve seen it. After all, the ancient era is tens of thousands of years ago, so it’s not surprising if some strange beasts have had their names changed.”

“I just pinpointed about ten snow caves. Zi Yin, why don’t you help me scan them with your Divine Sense?”

“Get lost. There’s no way this King will be your ‘laborer’ again.”

Tianxie Ziyin suddenly said in a fit of rage.

Yang Che shook his head helplessly and had no choice but to explore these snow caves himself, one by one.

According to Ma Qiucheng, he was originally from Yi Country, and his family had lived in a small village near the Thousand Snow Caves for generations.

Later, a terrifying ‘Snow Demon’ appeared here and slaughtered the small village.

At that time, Ma Qiucheng, who was just a child, happened to be chasing a strange small beast and ran into a snow cave, thus escaping the calamity.

Later, among the many Cultivators who pursued the Snow Demon, one happened to be a Qing Jian Sect Cultivator on an outing for experience. He discovered that Ma Qiucheng had an Immortal Root, so he directly brought him back to the Qing Jian Sect.

Afterward, in the Qing Jian Sect’s Spirit Beast Pavilion, Ma Qiucheng accidentally learned that the small beast he had chased back then was actually the famous ‘Nie Yun Sable’.

And after learning about the Nie Yun Sable’s habits and its innate Heaven-Defying ability to ‘seek treasure,’ Ma Qiucheng was overjoyed.

He originally planned to secretly return to the Thousand Snow Caves alone to capture this Nie Yun Sable and tame it as his Spirit Beast.

However, his cultivation was too low; firstly, he wasn't confident he could capture the Nie Yun Sable, and secondly, he was afraid of being coveted for its treasure. If other Cultivators with higher cultivation discovered it, he wouldn't be able to keep the sable and might even invite a deadly disaster.

So he kept this secret deep in his heart, secretly planning that once he reached Foundation Establishment, he would definitely return to the Thousand Snow Caves to capture this Nie Yun Sable.

However, after Yang Che saved his and Junior Sister Xiao Nan’s lives that night, he felt he had nothing presentable to offer in gratitude, so he simply told Yang Che this ‘secret’.

At this moment, Yang Che was treading on accumulated snow, going deeper and deeper into one of the caves.

The Nie Yun Sable has a habit: once it chooses a dwelling cave, it will always stay in that cave.

Even if it goes out ‘treasure seeking,’ it will eventually return to its dwelling cave.

Yang Che didn't tell Tianxie Ziyin about the Nie Yun Sable’s Heaven-Defying ability to seek treasure because he had a sudden idea and wanted to give her a ‘surprise’.

Even after reaching the deepest part of the snow cave, Yang Che still found nothing.

Yang Che had no choice but to continue to the next snow cave.

Thus, only two of the pinpointed snow caves remained.

If these two snow caves also didn’t contain the ‘Nie Yun Sable,’ then the possibility of finding it in other snow caves would be even more remote.

Yang Che, as before, directly set up the ‘Small Reverse Chaos Four Symbols Array’ at the cave entrance before stepping into the snow cave.

Seeing the winding paths inside, his heart suddenly became a little excited.

This snow cave was clearly very different from the previous ones.

Yang Che carefully sniffed with his nose and indeed smelled a faint Yao Beast aura.

He continued to move deeper inside.

Just then, a white shadow suddenly pounced towards Yang Che.

Its speed was as swift as lightning; if not for his Flash Cloud Boots, he would have almost been directly clawed in the face.

The white shadow, missing its strike, immediately turned into a streak of light and shot out of the snow cave.

Yang Che twisted his body, pushed off with his foot, and instantly leaped to the snow cave entrance.

He saw a small sable, completely snow-white, triggering the attack of the ‘Small Reverse Chaos Four Symbols Array’.

Four beams of light, each of a different color, directly forced the snarling little sable to retreat step by step.

“It’s a ‘Treasure Seeking Sable’. You insect, you actually kept this from this King. If you had told me it was a Treasure Seeking Sable, this King would have just caught it for you.”

Tianxie Ziyin’s voice, though still cold and with a hint of faint complaint, subtly revealed a trace of unprecedented joy.

Yang Che chuckled, preparing to use the ‘Instant Teleportation’ Divine Ability of the Flash Cloud Boots to forcibly capture this terrifyingly fast little sable.

However, Tianxie Ziyin said, “Don’t waste your energy. With your current cultivation, at most, you can barely use the Flash Cloud Boots’ Instant Teleportation Divine Ability three times, but this Treasure Seeking Sable’s speed far exceeds your imagination. And once you fail to catch it and instead enrage it, it will be even more difficult to tame this sable.”

As soon as Tianxie Ziyin finished speaking, Yang Che found himself being forcibly possessed by her.

His vision blurred, and the completely snow-white Nie Yun Sable was already caught and directly taken into the Void Illusion Magic Stone Space.

Yang Che regained control of his body.

Immediately, he heard Tianxie Ziyin say again, “This King will help you tame it. You should hurry to the end of the Mist Hidden Sea Region now and prepare to enter the ‘Boundary Battlefield’.”

Yang Che responded and immediately rushed out of the snow valley, speeding towards the Mist Hidden Sea Region.

Along the way, Tianxie Ziyin continued to explain many things about the Boundary Battlefield to him.

And for this trip to the Boundary Battlefield, Tianxie Ziyin repeatedly emphasized to Yang Che that no matter the circumstances, preserving one’s life was always the top priority.

“Yang Che, remember this well for this King. Preserving your life is always the first priority. Everything else can be ranked after this. If this King’s prediction is not wrong, many familiar faces from the Mist Hidden Realm will enter the Boundary Battlefield this time. Remember, you must never be soft-hearted.”

Tianxie Ziyin’s voice was unusually solemn, imbued with an inexplicable and unidentifiable majesty.

Yang Che naturally kept it firmly in mind.

Approximately a month later.

Yang Che, carefully disguised, finally managed to reach the very end of the Mist Hidden Sea Region.

From a distance, he saw a dense crowd of Cultivators gathered on a not-so-large island.

In the center of the island’s high altitude, a stoic Nascent Soul cultivator with almost no emotion on his face stood with his hands behind his back, constantly staring at a certain spot on the sea surface.

“This person should be the envoy sent by the Fifth-Grade Realm, Xuanwu Realm. Once the time comes, this person will open the Boundary Battlefield entrance.

This Boundary Battlefield should only be accessible to people from the Mist Hidden Realm and the Seven Alliance Realm. Yang Che, be prepared at all times. The moment you enter the battlefield might be unforgettable for the rest of your life.”

After Tianxie Ziyin finished speaking, Yang Che saw the stoic Nascent Soul cultivator suddenly take out an oval mirror and shine it at a certain spot on the sea surface.

A burst of colorful light erupted, and a strange rift that appeared out of thin air grew larger and larger, eventually stretching several miles long, spanning across the sea surface, a magnificent sight.
