Underground Discovery, Seven Feet Light of Seven Emotions Finally Completed

Immortal Golden nature was a characteristic that Cui Heng possessed after refining his Golden Core.

If the Golden Core was not destroyed, the body would not be destroyed.

Even if there was only a drop of blood or even an extremely thin trace of residue left, he could still revive.

And the center of a Golden Core was the Immortal Golden nature.

To a Golden Core cultivator, the Immortal Golden nature was something that could not be erased or destroyed. Even if a cultivator's lifespan was exhausted, and their physical body died, and their spirituality had dissipated, their Golden Core would still exist.

Therefore, even the most ordinary early-stage Golden Core cultivators could not be killed.

At most, they could be suppressed and sealed.

Only by nurturing a Nascent Soul and truly leaping to another higher realm would one have the power to destroy the Immortal Golden nature and kill a Golden Core cultivator.
