Ten Thousand Year Profound Ice Marrow!

He stopped thinking about it for now. They would wait until Xu Nianshuang finished absorbing her Soul Ring before investigating further.

Afterward, everyone cleaned up the area. The corpses of the four Soul Beasts could not be wasted; they were excellent materials for crafting Soul Tools.

Two hours later, Xu Nianshuang successfully finished absorbing the Soul Ring. The moment she opened her eyes, she excitedly threw herself into Xu Tianyang's arms.

The people around them immediately wore indulgent smiles as they watched the pair, who seemed like a match made in heaven.

Xu Tianyang gently held Xu Nianshuang. Judging by her expression, the result must have been perfect.

"Alright, alright. Tell us, how were your gains this time?"

"Tianyang, just as you predicted, my second soul skill is the Ice Explosion Technique. And my Soul Power has broken through to rank twenty-three. I've caught up with you again." The gazes around her made Xu Nianshuang realize what she was doing. Her cheeks flushed slightly as she left Xu Tianyang's embrace, speaking with excitement.

Xu Tianyang was somewhat surprised, then analyzed, "It should be due to the Dragon Pattern Whale's Whale Rubber. Coupled with the fact that this Ice Devouring Ant was a two-thousand-year Soul Beast, the energy it contained was considerable. That's why your Soul Power reached rank twenty-three immediately after breaking through."

"Looks like I'll have to work hard. Otherwise, you'll catch up to me again before I know it."

"Your Highness, our objective for this trip has been achieved. Before night falls, we should return." At that moment, Min Yingying walked over and looked at the sky.

"No rush. I just made a new discovery. There seems to be something in the valley ahead attracting those four Soul Beasts. For them to fight over it, it must be no ordinary treasure. Let's investigate quickly and return before dark." Xu Tianyang slowly explained his thoughts.

Min Yingying pursed her lips and exchanged a glance with Meng Tao. In the end, she did not refuse. With their strength, they were more than capable of ensuring the two youngsters' safety in this outer region.

Once the decision was made, no one delayed. They quickly took out their Flying Soul Tools and flew toward the distant valley.

In less than ten minutes, they arrived inside the valley. The entire valley was an irregular ellipsoid, with its longest span exceeding two thousand meters.

The valley was a vast expanse of white, filled with many Ice Attribute plants. It could be considered lush with life, yet there was no trace of any Soul Beasts. This was an ownerless land.

To speed up the search, everyone spread out to explore. Xu Tianyang likewise released his spiritual perception as he headed deeper into the valley.

"Tianyang, something over there seems different." Xu Nianshuang, who had been following Xu Tianyang, suddenly tugged him and looked toward a cliff more than fifty meters high in the distance.

At first glance, there was nothing unusual about the cliff. However, Xu Tianyang's sharp eyesight told him that the light around one particular spot seemed different.

"Sister Yingying, take us over there."

Following the direction Xu Tianyang pointed, Min Yingying controlled the Flying Soul Tool and carried the two of them over. At the same time, she activated Martial Soul Possession, prepared for any sudden developments.

Upon drawing closer, the three discovered that it was actually a thick slab of Ice Crystal. There appeared to be an enormous cave within it.

Seeing this, Xu Tianyang activated Martial Soul Possession with his Sun Pupil. One yellow and one purple Soul Ring floated beside him. As his Soul Power circulated, blazing firelight gathered in his eyes. The next moment, two scorching beams of flame shot from his pupils and slammed into the ice wall.

"Sizzle, sizzle, sizzle..."

The terrifying heat melted the ancient solid ice, and an enormous cave appeared before them. Upon entering, they found that the entrance was more than ten meters in diameter. Its interior was spacious and empty, radiating an azure glow.

"The Ice Attribute energy here is much more active than outside!" After entering, surprise appeared in Xu Nianshuang's eyes.

"Looks like we found the right place." Xu Tianyang smiled at her words.

The group searched through the cave and soon found an Ice Crevice. The crevice was small, no more than fifty meters long and no more than one meter wide, but its depth was unknown.

"The closer we get to this place, the more active the Ice Attribute energy becomes. This must be the key to the anomaly here." Xu Nianshuang closed her eyes to sense it for a moment, then slowly spoke to the others.

"Your Highness, I'll lead the way." Meng Tao activated Martial Soul Possession and took the lead as he flew down into the Ice Crevice.

As they descended, the space within the Ice Crevice actually grew larger and larger. After descending for ten minutes, they landed on the ground. Who would have thought that the narrow crevice above concealed a massive space nearly a thousand meters wide below?

The cave was covered everywhere in solid ice, while white frigid mist filled the air. The ground was uneven and pockmarked, and many icicles hung from the ceiling, the longest nearly touching the ground.

"It's actually this cold here." Frigid air enveloped everyone. Min Yingying and Meng Tao could not help frowning. Neither of their Martial Souls possessed either fire or ice attributes, so they could not resist the low temperature and could only endure it through their formidable cultivation.

"This is... There are actually Extreme Ice Divine Crystals here?!" A cry of surprise rang out. Meng Tao was looking at the distant cavern, delight written across his face.

In the distant ice cave, azure crystal ores densely covered the area. The ores were translucent and gleaming, possessing a dreamlike beauty beneath the light.

"Extreme Ice Divine Crystals!" Xu Tianyang's expression shifted. Although Extreme Ice Divine Crystals were top-tier materials for crafting Soul Tools, there was something even more precious: Ten Thousand Year Profound Ice Marrow.

Sky Dream Ice Silkworm had absorbed Ten Thousand Year Profound Ice Marrow and directly reached the million-year level. Snow Empress and Ice Empress had even stated outright that if they possessed Ten Thousand Year Profound Ice Marrow, they could survive their seven-hundred-thousand-year and four-hundred-thousand-year Heavenly Tribulations.

For Ice Attribute soul masters, Ten Thousand Year Profound Ice Marrow was a treasure on par with Immortal Grade Herbs.

And Extreme Ice Divine Crystals were precisely the companion ore of Ten Thousand Year Profound Ice Marrow. Given the situation here, there might truly be Ten Thousand Year Profound Ice Marrow present.

"What a pity. Extreme Ice Divine Crystals are difficult to mine, especially in this ice cave." After his initial excitement faded, Meng Tao considered their current situation and could not help sighing regretfully.

"Make a note of this place's location. When we return, report it to Imperial Father. There will always be an opportunity to mine these Extreme Ice Divine Crystals someday." Xu Tianyang said as he looked at Meng Tao's regretful expression.

As he walked through the vein of Extreme Ice Divine Crystals, Xu Tianyang released his Spiritual Power without reservation, unwilling to overlook a single detail.

Seeing that Xu Tianyang seemed to be searching for something, the others did not dare speak and quietly waited.

"Found it!" After a long while, Xu Tianyang's eyes lit up. Looking at an ice wall, he said, "Sister Yingying, blast it open."

Upon hearing this, Min Yingying carefully released her Martial Soul. Her fourth Soul Ring lit up, and a powerful attack struck the place Xu Tianyang had indicated.

"Boom!" A dull sound rang out. Everyone stared in surprise. Min Yingying's attack had only opened a half-meter-wide hole in the ice wall.

Through the opening, Xu Tianyang saw inside. The cold within was even more terrifying, making it feel as if one's very soul would be frozen. Even the surrounding air seemed to have grown viscous.

The ice element contained within was extraordinarily dense—so dense that low-level soul masters simply could not absorb it.

A strange pillar of ice stood within. It was as white as jade, and liquid seemed to flow faintly inside that pristine ice pillar. The terrifying chill was being released from it.

"Ten Thousand Year Profound Ice Marrow!" Xu Tianyang looked at the ice pillar, drew a deep breath, and spoke in a low voice.

"Let's go. We're leaving." After confirming it, Xu Tianyang led everyone back the way they had come. As for why they did not take the Ten Thousand Year Profound Ice Marrow, it was because none of them could manage it.

The terrifying frigid aura released by the Ten Thousand Year Profound Ice Marrow made it impossible for them even to approach it, let alone take it away.

After returning to the valley, Xu Tianyang looked at the darkening sky outside, then solemnly addressed Min Yingying and Meng Tao. "Sister Yingying, Uncle Tao, I need you to notify Imperial Father immediately and have him come here personally. Tell him I've made an important discovery. You must have him come personally..."

"If Imperial Father cannot come, then Imperial Mother and Uncle Feng must come."

"Before Imperial Father arrives, send people to guard this valley. Do not allow a single Soul Beast to approach this place."

Hearing Xu Tianyang's words, confusion appeared on their faces. Were these Extreme Ice Divine Crystals really that important?

His Majesty had to come in person?

However, seeing Xu Tianyang's solemn expression, neither dared take the matter lightly. What if there was some secret involved that they did not know about? Their orders were to obey the Crown Prince Your Highness in all matters. Since it was His Highness's command, they only needed to carry it out.

Xu Yunxiao soon arrived at the North Sea. After Xu Tianyang explained everything, he finally understood what kind of treasure the Ten Thousand Year Profound Ice Marrow was.

Without further delay, the Destructive Attribute of a Titled Douluo-level Purple Blazing Heaven Dragon was more than enough to solve the problem that had stumped Xu Tianyang's group.

Xu Yunxiao personally took action and naturally removed the Ten Thousand Year Profound Ice Marrow with ease. He then immediately returned to Mingdu with the Ten Thousand Year Profound Ice Marrow and Xu Nianshuang.

He had only come here in the midst of a busy schedule. The Sun Moon Continent had only just been unified, and countless matters required his decision as emperor. Every day, not only did he have endless governmental affairs to handle, but he also had to oversee the major research projects Xu Tianyang had proposed.

He was busy!

So busy that his feet barely touched the ground every day.

Had Xu Tianyang not repeatedly stressed the importance of the Ten Thousand Year Profound Ice Marrow, he would not have come personally.

Now that the Ten Thousand Year Profound Ice Marrow had been removed and Xu Nianshuang had successfully broken through, the two did not stay long.

With the aid of the Ten Thousand Year Profound Ice Marrow, the path to Xu Nianshuang becoming a Titled Douluo had already appeared. She could even cultivate all the way to rank ninety-five without encountering any major bottlenecks.
