To invade the opponent's Inner Realm, the first step is to integrate your own Spiritual Power into their Inner Realm. This way, you can bring their Inner Realm to the same level as yours. Consequently, the opponent's Inner Realm will manifest the concept of "you within me, me within you," allowing the Inner Realms to pull against each other, preventing the opponent from unleashing the god-like power of their domain.
At this point, everyone relies on their own abilities and the real test comes under one's hand.
But in reality, in this state, it's one's own Inner Realm that suffers the losses, for if the Inner Realm is damaged by the aftermath of battle, the situation becomes extremely dangerous.
After all, the Inner Realm can truly be deemed as the foundation of attaining Tao. It stems from the very beginning, and if the Inner Realm is destroyed, there can no longer be any progress forward.
