In this universe.
In ordinary domains, such as the cosmic starry sky or the Jade Toad Great Heaven and Earth, because the Ancient Immortals from the Immortal Ancient Period have either passed away or fallen, even if their true names are chanted, it is often difficult to receive a response, making it impossible to borrow power.
Only in special domains like the 'Immortal Fall Battlefield' does the power of the Ancient Immortals linger. Thus, True Immortals like Emperor Lingchuan and Emperor Bai Zhu, who come from ancient forces and possess the true names of Ancient Immortals, can harness the power and perform 'Immortal Techniques' that resemble Divine Skills but are augmented by the mighty power of the Ancient Immortals, rendering them invincible at the True Immortal level.
For example, the 'Divine Mechanism Great Universe Immortal Technique' of Emperor Lingchuan.
