Yin Xiang's Intelligence!

"It absolutely cannot be allowed to spread within the Eastern Domain."

Lin Ye dismissed the idea. The Eastern Domain had a large population, including one Great Emperor, three great dynasties, and hundreds of kingdoms, each with a considerable population. For example, a small country like Chu Kingdom had about 20 million people. If the entire Chu Kingdom were developed into a place of demonic martial artists, the mission could be completed.

However, this is actually impossible.

First, some are children, and some are elderly people who simply cannot cultivate. This would reduce the population by half. There are also more than 90% ordinary people with very average aptitude. In addition, it is impossible for everyone to cultivate, otherwise the entire country would not be able to function.

Even if the entire population were trained, the maximum number of demonic martial artists that could be developed would be one million. That would be the limit. We would need to find ten such countries to fully develop the demonic path, and then it would be impossible to hide.

Therefore, Lin Ye did not plan to do it in the Eastern Domain, and the other eight regions of the Profound Heaven Realm were not good choices either. The best choice was within the small world.

Some small worlds also contain humans, and in considerable numbers. For example, some Taboo Being or Taboo Sovereign secretly cultivate humans, harvesting them periodically, but not killing them all to ensure a stable population in the small world. Some of these small worlds contain hundreds of millions of people.

"If I could occupy such a small world and fully develop the demonic path, wouldn't I be able to complete the mission?" Lin Ye was eager to find such a small world as soon as he thought of this.

So he issued this task, asking his disciples to find relevant clues. They didn't need to find such a small world; as long as they provided useful clues, they could earn a large number of sect points.

Soon, all the disciples saw the task and began to discuss it.

"Master is looking for a small world with a large population, at least hundreds of millions of people. Does such a small world exist?"

"There should be, otherwise why would Master issue such a task?"

"Such a small world must be hard to find. I've spent a lot of time traveling and visiting many countries, but I've never encountered one like this."

"Never mind, let's take this mission for now. If we encounter it again during future training, we'll tell Master."

These disciples took on tasks one by one, since no timeframe was mentioned from above.

After Yin Xiang emerged from seclusion, she also saw this mission and immediately became curious.

"Why would Master seek out such a small world? And why mention over a hundred million people?" Yin Xiang was very curious. If Master were Taboo Being, she would understand; it would undoubtedly be about reaping lives. But Master wasn't, and he could even take out the elixir of immortality at any time. It was impossible for Master to have such thoughts.

"Could it be that Master wants to expand his power? But that doesn't make sense. The Spiritual Qi concentration in a small world is limited, definitely far inferior to that of the Profound Heaven Realm. In addition, the Principle of a small world restrict cultivation, making it more difficult. Many small worlds can only allow cultivation to reach the Golden Core Realm at most, and it's also difficult for small worlds to produce any monstrous geniuses, so they're not very valuable."

Yin Xiang really couldn't understand why Lin Ye would issue such a mission. However, as a former Great Emperor, her memories were only vague, not gone. She still knew a lot of information, although some of it might not be accurate. After all, her existence was too far removed from the present, and many alien races and small worlds might have been destroyed.

"Let's go check those places first. If they're still there, they might be able to meet Master's requirements."

Yin Xiang left the sect and headed to a place in the Profound Heaven Realm. With her current Saint Realm cultivation, her level of understanding of the Embryonic Principle, and her numerous Emperor Techniques, she would have a chance to escape even if she encountered Quasi-Emperor, unless she was extremely unlucky and encountered a Great Emperor, in which case she would be killed.

However, the Immemorial Immortal Road has not yet officially opened, and the Dark Age is only the beginning. Those Great Emperor and Taboo Sovereign are still observing, so the possibility of her encountering them is very, very low.

From what she knew, the Immemorial Immortal Road would only appear after a Great Emperor was born in the Profound Heaven Realm. In this era, everyone's goal was still to compete for the Emperor Road.

The competition for the Emperor Road in the Eastern Domain is not yet very obvious, but in the other regions, many geniuses are fighting fiercely, and the battle for the Emperor Road has already begun. Everyone's focus is on the other regions, and the Eastern Domain is unlikely to receive much attention.

One day later.

Somewhere in the Eastern Domain, Yin Xiang arrived at a dilapidated valley. She formed hand seals, and spatial ripples appeared. Soon, a broken little world appeared in her perception.

"The world has been destroyed, leaving only a shattered fragment."

Yin Xiang wasn't too surprised by this result. There was indeed a small world here, with about 100 million people. It was a small world under the command of Taboo Sovereign, who secretly cultivated 100 million people.

After she broke through to the Great Emperor, in her later years, she discovered this place and fought against this Taboo Sovereign. Relying on the fact that the Taboo Sovereign was relatively weak, she managed to kill him, and then sealed this small world away.

But now it seems that this little world has been discovered, and we don't know what happened, but even this little world has been shattered.

"Let's go somewhere else!"

Yin Xiang left this place and went to the second place, but the second place was completely gone, not even a trace remained, let alone any fragments; it had been utterly reduced to nothingness.

The world has changed drastically over time. Even the land of the Profound Heaven Realm has undergone tremendous changes, with many small worlds shattered and even many ancient grotto-heavens reduced to Primordial Fragment.

Yin Xiang investigated several small worlds in the Profound Heaven Realm that might have hundreds of millions of people, and found none of them. She spent half a month traveling throughout the Nine Domains before confirming that such small worlds most likely did not exist in the Profound Heaven Realm.

"We can only go outside the Profound Heaven Realm, but the outer void outside the Profound Heaven Realm is very dangerous, and I dare not go to investigate."

Yin Xiang returned to the Black-Yellow Sect, intending to inform her master of the clues about several small worlds outside the realm. If her master went to investigate, the danger should be very low.

She can now roughly judge her master's strength; he is definitely not weak among the Great Emperor, and since her master has an avatar, it would be very convenient for him to investigate.

So she went to find her master Lin Ye.

"Master."

Yin Xiang said respectfully.

"Yin Xiang, what's wrong?" Lin Ye asked.

Yin Xiang revealed, "Master, I found several small worlds within ancient ruins that may contain hundreds of millions of people, but they are all outside the Profound Heaven Realm. I am not sure whether these places still contain small worlds and hundreds of millions of people."

Give me a clue.

Lin Ye has confirmed that Yin Xiang is a reincarnated Great Emperor, and likely a very ancient Great Emperor at that. The information may not be entirely accurate, but having a clue is enough. Perhaps those small worlds really do contain hundreds of millions of people.

Immediately, Yin Xiang gave Lin Ye the coordinates and general information of those small worlds.
