At this moment, on a battlefield in the future Tang Domain, the remaining millions of beings in this domain huddled together.

Numbness and despair were etched on everyone's faces. The battlefield, where blood flowed like rivers, reflected the sky in crimson, and the endless crimson clouds testified to the ferocity of the battle.

Of the countless creatures in a vast domain, only a few million survived.

Ling Yun walked up to an old man and said:

"Go to the inner world; it's safe there!"

The old man was the ancestor of the Fire Flame Clan, and also the ancestor of Xiao Yanran's previous incarnation, Xiaoyaoran.

"Thank you for your guidance, senior!"

The old man immediately recognized Ling Yun as an unparalleled being, and the path he pointed out was absolutely safe.

Ling Yun nodded slightly, and with a wave of his hand, a spatial gate appeared.

Everyone bowed deeply to Ling Yun before entering the spatial gate to travel to the Earth's core.

After closing the spatial gate, Ling Yun also sealed the entrance to the Earth's core. The seal will automatically be released after several years.

After doing all this, Lingyun, Qiongqi, Dasheng, Huangdi, and Abao looked back at the myriad realms, their hearts filled with mixed emotions.

Having personally experienced the apocalyptic war, the brutality of which filled them with fear and desolation.

The myriad worlds of this era were more than ten times larger than those of the future, but this battle severely damaged the World Tree, causing the endless universes to become nothingness.

After a dizzying spin, Ling Yun and the others returned to the real world.

In front of them was a stone wall, bare and devoid of anything.

"Huh? Are we supposed to be facing the wall in repentance?"

Qiongqi looked at the stone wall with a mixture of doubt and amusement.

The Great Sage, the Yellow Emperor, and A Bao looked at each other, only remembering that something on the stone wall had attracted them, but they couldn't remember what it was at all.

He doesn't even remember his own great achievements in saving a great world.

Ling Yun frowned deeply, completely baffled.

“I feel like we must have gone through something, but that memory has been erased!”

Ling Yun murmured.

“Me too!” The Great Sage scratched his head and said, “I vaguely remember Yinglong, Chaos, Taotie and the terrifying war of the apocalypse! But these memories are also starting to fade away.”

Wait, I don't remember anything!

Qiongqi, Huangdi, and Abao spread their hands, indicating that they were the same.

After a pause, Ling Yun said:

Let's continue!

The gentle force continued to carry Ling Yun and the others downwards, and this time the descent was very fast.

About a day later, the group arrived at the bottom of the valley.

The valley floor was brightly lit, exuding a gentle atmosphere.

"There are probably some amazing treasures at the bottom of the valley. Let's split up and search!"

Ling Yun spoke up.

Immediately, everyone dispersed, and Lingyun and Abao sensed the aura of the Yin-Yang Stone together.

The two walked in the canyon for a long time before stopping in front of a large rock. The source of the Yin-Yang Stone's energy was in the boulder.

"Brother, the Yin-Yang Stone is inside this stone. I can sense the primal power within my body stirring and reveling!"

Abao exclaimed excitedly.

Ling Yun nodded slightly and raised his hand to shatter the boulder.

With a loud bang!

The boulder shattered, and a perfectly round stone, three inches long, floated in the void.

Each side of the round stone is shaped like a yin-yang symbol, rotating and radiating unparalleled yin-yang power.

It is the legendary Yin-Yang Stone, possessing the complete origin of the Dao. If it is fully refined and comprehended, A Bao may truly become the Dao Ancestor.

"Go and take it; this is your destiny!"

Ling Yun smiled.

Ah Bao nodded emphatically, holding the Yin-Yang Stone in his palm, his blood instantly surging.

The Iron-Eating Beast Clan is known as the embodiment of Yin and Yang power, and is naturally suited for cultivation.

With a whoosh!

The Yin-Yang Stone disappeared into A Bao's brow.

Leave a yin-yang symbol the size of a fingernail between his eyebrows.

At the same time, the Yin-Yang Stone slowly decomposed within his body, entering his bloodline and continuously increasing the purity of his bloodline.

In an instant, A Bao's blood energy surged wildly, seemingly perfectly merging with the Yin-Yang Stone.

Seeing this scene, Ling Yun was extremely shocked. He had joked before that A Bao would become the Dao Ancestor, but now it seemed that it was no joke.

Ah Bao might actually become the Dao Ancestor!

"Wow~ My little brother is going to be the Dao Ancestor?"

Ling Yun exclaimed in surprise.

Ah Bao was so shocked he couldn't speak, and stammered:

"I...I really...could become a Dao Ancestor?"

Ling Yun nodded, "As long as you cultivate normally and comprehend the Dao essence within the Yin-Yang Stone, there is a high chance of becoming a Dao Ancestor."

Ah Bao pressed his hand to his chest, trying to calm himself down.

At this moment, the Yellow Emperor let out a scream—yes, a scream.

Lingyun, Abao, Qiongqi, and the Great Sage rushed over.

They saw the Yellow Emperor staring in shock at the storage bag.

"What's wrong with Lion Brother?"

The Great Sage was puzzled.

The Yellow Emperor took several deep breaths to calm himself and handed the storage bag to the Great Sage.

The Great Sage glanced at it, immediately covered his mouth, and threw the storage bag to Qiongqi.

Curious Qiongqi opened it and immediately his tiger eyes widened and his breathing became rapid.

He hurriedly tossed the storage bag to Ling Yun.

Although Ling Yun remained calm after reading it, his pupils had shrunk to a tiny size.

"What is it?" Abao's curiosity was completely piqued, and he leaned over to take a look at the storage bag.

"Immortal...Immortal...Immortal Mother Green Copper!"

Ah Bao exclaimed in surprise, his voice trembling with fear.

The storage bag wasn't just a piece of green copper, nor was it weighing ten thousand jin; it was made from an entire mountain of green copper.

This mountain is as big as hundreds of Qiongqi's original form.

Ten eras couldn't find so much Celestial Mother Green Bronze. No wonder the Yellow Emperor screamed, and even Ling Yun almost couldn't help but scream.

With so much Celestial Mother Green Copper, it's enough to forge countless Celestial-grade magical artifacts, easily enough to arm trillions of cultivators.

In the final battle against the Primordial Race, the Fairy Mother Green Copper will play an unparalleled role.

It took everyone a while to calm down.

Ling Yun seemed to have figured it out and said:

“I deduce that we did the Guardian of All Things a favor, and he rewarded us with Fairy Mother Green Bronze.”

Although Qiongqi and the others found it unbelievable, Lingyun's words were generally quite reliable.

The group continued their search at the bottom of the valley, turning it upside down, but they still couldn't find the treasure.

Immediately, Ling Yun and the others decided to leave.

As if by telepathy, a gentle force immediately rose from beneath their feet, lifting Ling Yun and the others upwards.

As they passed a mountain wall, they were surprised to see a neatly written character for "thank you," which was directly opposite the stone wall with the character for "save" they had seen earlier.

The word "thank you" flashed by, and so did the memory.

In less than fifteen minutes, Lingyun and his group returned to the outside world from the bottom of the valley.

The outside world remained as usual, filled with the terrifying aftershocks of a battle at the Immortal Emperor level.

To Ling Yun and his companions' utter astonishment, a safe road suddenly appeared.

They walked on it tentatively, and there was not a trace of the aftermath of the battle.

"How strange!" Qiongqi rubbed his head, puzzled.

The same applies to Ling Yun and the others.

It's a good thing that they've stopped overthinking it.

The road was only a hundred feet long. When they reached the end, Lingyun and his companions found that they had arrived at the exit of Demon Cloud Valley.
