Evian picked the two very best Cultivation Manuscripts he could find and put them in his ring but he put the rest in the ring he got from Yvette.
As he had no connection with Yvette's ring, he couldn't view the contents but that didn't stop him from placing it against any object he wanted to store and watch as they were sucked in.
Although he kept a sizeable heap of the Larnak Gold, having never had much use for tangible wealth anyway (since the currency of his Decadence was Soul Points), Evian put the vast mountains of the Gold in Yvette's ring.
Every piece of jewelry that appeared Feminine (the majority) he put in Yvette's ring as well while he kept the manly-looking ones mostly for potential taunts. He had no real interest in decking himself with them.
He also kept the Weapons in Yvette's ring, glad it had the space to accommodate it all. He had no interest in any of them.
