Lu Wenwu ultimately couldn't capture an upper realm Immortal God to work for him.
After all, even if both sides joined forces to face the enemy, organizing negotiations would still take some time.
Moreover, with the current state of the Three Realms, the resources required for the upper realm to send someone down are indeed immense.
Gathering enough resources is not something that can be accomplished overnight.
The last time they sent down the True Monarch of Destiny, it already drained the reserves of several high-ranking members of the Immortal Realm. The Celestial Emperor even used his own inner treasury to barely gather enough resources to reverse the Celestial Gate.
Not to mention, the Divine Realm still doesn't fully believe the Celestial Emperor's words, and both sides remain in a stalemate.
