"If this human body can reach the Earthly Immortal realm, combined with my demonic essence and demonic spirit clone, I will possess three legendary powers of different natures."

Logically speaking, when a legendary creature is split into three, each power will be weakened to one-third of the original, and for the clone to retain half of its strength, it can be considered a powerful secret method of cultivation.

The more you divide, the less power you have, and it is very difficult to cultivate the clone to the legendary level again. At least for most legendary creatures, it is impossible to do so.

At least in the entire world of Avalon, there is no record of any strong person who possesses the legendary authority of three different rules.

But Xu Xianxian did it.

"Although there are many doubts and cautions about the Demon Spirit clone's achievement of legendary status, as long as I return to Earth, I will directly use the absolute control of my true spirit to eliminate the clone's personality."

"Then..."

"Tao gives birth to one, one gives birth to three, the trinity is the ultimate force, impacting the realm of demigod."

Even if she didn't jump into the River of Time, the superposition and fusion of the triple legendary authority was enough for Xu Xianxian to cross the three levels of the legendary creature and reach the realm of demigod.

This is pure force breaking the law.

The addition of powers is not as simple as one plus one equals two. As long as the integration is successful, it will increase exponentially.

The superposition and fusion of the three powers are enough to form a perfect iron triangle rule, thus producing an unimaginable magnitude, dozens or even hundreds of times, to trigger this qualitative leap.

Xu Xianxian knew that it was imperative to practice the Dark Extreme True Soul Art to the fifteenth level.

It is neither simple nor difficult.

As long as she could completely devour the essence of a legendary creature, she would be able to naturally allow this human clone to reach this level.

However, even if some legendary creatures have weaker combat capabilities and can be defeated or sealed, it is very difficult to kill them, let alone devour their essence.
