In the realm of immortal cultivation, when everyone goes out for a great battle, they generally won't bring too many things.
After all, in a great battle, no one can guarantee a certain victory, and if one loses, then the treasures brought along would end up in someone else's possession.
Therefore, when the Red Refinery Demonic Sect and the Sun Moon Demon Sect and others attacked the Hundred Peaks Sect before, those who died didn't leave behind too many valuable treasures, the most common being their Qiankun Bags, followed by their Divine Weapons.
Other things might not be brought along, but Divine Weapons definitely would be.
And the Qiankun Bags also need to be brought, for if they breached the Hundred Peaks Sect, there would indeed be things to plunder.
However, this time was somewhat different.
The group led by the Eclipse Demon indeed only brought a Qiankun Bag each, with not many treasures inside the bags.
