“It’s a very convenient method of inheritance…” Mo Yan nodded.

After searching for a while, no more magical treasures were found in the ice chamber. At this moment, Shen Yunhao noticed that a hint of black was faintly visible among the several ice crystal skeletons under the stone platform.

After thinking for a moment, Shen Yunhao wrapped himself in a protective shield formed by runes in his palm and slowly walked forward.

Sure enough, with the ice talisman by my side, I was not affected by the crystallization.

Shen Yunhao turned over the skeleton, and underneath lay a palm-sized round stone disc with some simple stripes carved on it, which looked quite ordinary.

"What is this?" Shen Yunhao picked up the stone plate and examined it, but found nothing.

"Keep it for now."

Mo Yan had already walked towards the exit at the other end of the ice chamber. "There's nothing else here. Let's go... and see if there are any other exits behind us."

The two left together. Behind the exit was a downward-sloping passageway where the temperature dropped lower and lower, and even their breath would instantly condense into ice jelly.

After walking for about half an hour, the sound of flowing water came from ahead. Before long, a rushing underground river stretched across the end of the passage.

The river was as black as ink, yet strangely it did not freeze.

Shen Yunhao squatted down to test the water temperature and was surprised to find that the river water was significantly warmer than the water above.

What is the reason for this?

Mo Yan stepped forward to probe it and said calmly, "Because water has a relatively high specific heat capacity..."

"..."

Shen Yunhao looked at her expressionlessly.

"Suddenly, I feel like nothing here is as cold as your joke..."

"whispering sound!"

Mo Yan released her vines to survey the surroundings, then shook her head and said, "There are no other exits. The only way out is through this river... It seems we have no choice but to swim across."

"Swim across?"

His current cultivation level is only at the Profound Soul Realm. Although he has already abstained from grains, he has not yet reached the level of internal circulation of his breath. If he does not breathe for a long time, he may still suffocate!

Mo Yan seemed to have figured out what he was thinking, and pulled out a leaf from somewhere.

"Just hold it in, you won't suffocate... Besides, you have the Vast Ocean Heart, what are you afraid of? Surely the Vast Ocean Heart won't be useless in the river..."

Shen Yunhao then realized that because he hadn't used it for so long, he had completely forgotten about this important treasure he had on him!

But upon seeing this leaf, Shen Yunhao immediately thought of a certain silly little girl far away in the Demon Realm.

I wonder how Qing Teng is doing...

"What... do you want to talk to that silly girl?"

"May I?"

To everyone's surprise, Shen Yunhao did not hesitate and asked with delight.

"Hmph! No way!"

Mo Yan, annoyed, put her hands in her pockets and turned her head away.

"You wouldn't eat the meat that was placed right in front of you before, and now you're greedy? No way!"

"..."

To be honest, the vinegar smell is quite strong...

Shen Yunhao never expected that one day he would see Po Tengzi jealous of Han Tengzi.

However, Shen Yunhao did not ask any further questions about what Mo Yan said about not being allowed.

Even Bai Xiaoruo's tail lost its connection with her main body here, let alone Mo Yan and Qing Teng, who are two separate souls, their connection would inevitably be severed as well.

Shen Yunhao carefully put away the stone plate, held the leaf in his mouth, took a deep breath, and jumped into the river.

This was done just to be on the safe side. Was there any possibility that the Vast Ocean Heart wouldn't be usable in the river, or that the underground river here didn't originate from the same source as the water element that the Vast Ocean Heart could manipulate, making it ineffective here?

As it turns out, Shen Yunhao's guess was not without merit.

Although the Vast Ocean Heart could prevent him from suffocating in the water, he could no longer feel that "divine sense spreading" sensation!

The water here is clearly strange.

Surprisingly, although the river water looked pitch black, it was clear once you entered the water. The water was very deep, so Shen Yunhao did not choose to explore further, but instead followed the current downstream.

Time always seemed to pass very slowly underwater. Half an hour felt like an eternity to Shen Yunhao!

Suddenly, the current became rapid, and a bright light appeared ahead.

"Hold on tight!"

Shen Yunhao shouted, and the two of them were quickly drawn into a whirlpool and thrown out of the water as the world spun around them.

Finally seeing the light of day again, the long-awaited sunlight made Shen Yunhao squint slightly.

He found himself in a huge ice cave, with countless icicles hanging from the ceiling and the ground covered with fine blue snow.

Behind them was a pool of water, and water was spraying out like a small fountain. The two of them were "sprayed" out of the ground.

Directly ahead, a colossal blue crystal gate stood majestically! Thirty-six deep blue crystal cores were embedded in the gate, gleaming brightly!

"This is... the entrance to the third level of the Extreme Ice Castle!"

Shen Yunhao took a deep breath and immediately recognized the uniquely designed door.

This is also a place that Han Xiaozi's remnant soul described in detail!

"It seems... we made the right choice by taking this tunnel!"

Mo Yan used her spiritual energy to dry her wet purple hair, and seeing that Shen Yunhao was very clean, she pouted in dissatisfaction.

"Hmph! You stinky man, underwater you have the heart of the ocean but only care about yourself..."

Shen Yunhao was taken aback when he heard this, and then he noticed that Mo Yan's purple dress was already soaked by the cold water below, and now it clung tightly to her skin, vaguely revealing her slender figure.

Shen Yunhao couldn't help but swallow.

"Why don't you just stop baking it? It's fine as it is!"

"Go! Go! Go!"

The girl blushed and spat at him, "No way! I'll just have to endure your bullying again before we get very far!"

"..."

Sure enough, only the little sister truly understands the wicked plans in her little brother's heart...

At the same time, the gate to the third level of the secret realm trembled slightly, and thirty-six blue crystals lit up in turn.

The runes in Shen Yunhao's palm also began to glow on their own.

Clearly, Shen Yunhao's "door opening authority" still has room for improvement!

"It seems... the Void Realm is not far from us..."

Shen Yunhao stepped forward and looked at Mo Yan beside him. "According to that remnant soul, this third level is actually much safer than the first two!"

"Whether you believe it or not, I certainly don't!"

The girl, with her hands tucked in, walked ahead of Shen Yunhao...

Shen Yunhao shook his head with a faint smile, knowing that this girl was testing him to see if there was any danger.

Not long after, Shen Yunhao walked to the gate. This time, the gate could not be opened as he wished, so he raised his hand and pressed it against the center of the gate.

The moment the palm rune touched the blue crystal gate, all thirty-six crystal cores lit up simultaneously.

Complex chains of runes flowed across the surface of the door, eventually converging into two overlapping ring patterns, identical in shape to the runes in Shen Yunhao's palm.

"Just as I thought..." Shen Yunhao muttered to himself.

"Squeak..."

The door slowly opened, revealing a deep, dark corridor.

At a glance, Shen Yunhao saw that the interior of the castle was not covered by any ice crystals. The walls were smooth and flat, as black as ink, and the floor was paved with some kind of dark stone, engraved with fine silver patterns.

"They're here!"
