This dharma gate that forcibly elevates one's own strength is called forbidden technique in the Lower Realm, and in the Upper Realm it is even more forbidden among the forbidden.
Even the ant-like strength of creatures in the Lower Realm, when forcibly ignited, will damage their foundation and have to pay a painful price. The stronger ones will even die instantly after using it, making it a one-time means.
As for deities with unknown upper limits, the cost of using forbidden techniques is even greater, because creatures in the Lower Realm can still pray to the gods and Demon Gods for power, but to whom can the deities in the Upper Realm pray?
