The opportunity has arrived!
Setoras somehow learned the news and even made a deal with three Subsidiary Gods of Hades, tricking the Death Knight into Hell. The Devil Alliance surged forward, and at the cost of severe injuries to most of its members, they successfully captured this monster.
Had they not had the home-field advantage, and without the secret assault by one of the three Subsidiary Gods, 'Wings of Winter' Xizor, the outcome would be difficult to predict.
Hell is sealed by Heaven, making it challenging for Devils to descend to the Mortal World. The stronger the Devil, the harder it is to descend, and even if the descent is successful, the limitations are so great that they cannot fully exert their power.
Only if Hell Gate is opened can Devils perfectly descend.
The Devil Alliance cannot come to the Mortal World, but the Death Knight Rone can. Coupled with the unique topography of the Underground Great Tomb, it's enough to open Hell Gate and connect the two realms.
