The bow-wielding old man himself was very confused, but he had a feeling in his heart. These spoils must be put aside; they're someone's share.
In this war of revenge of their Thirty-Three Divine Beasts' Sect, that 'mysterious man' had played a key role during the fight.
But for some reason, he couldn't seem to remember anything about the 'mysterious man'. He couldn't remember who it was that helped them and caused those fake deities to become pregnant.
They made it so that all of the fake deities, regardless of whether they were male or female or neutral, trembled under the pain of pregnancy and childbirth. Thinking about it now, they should be a very terrifying 'mysterious man', right?
The more he was unable to remember who that mysterious man was, the more certain he was that they existed.
And that he definitely had to have a share of the spoils.
The bow-wielding old man kept the loot that he had set aside.
