I Have a Billion Summoning Scrolls

Zhang Yun is an old-school hoarder in games. For a special quest in Lost Kingdom, he’s been hoarding since launch, building up his stockpile for ten years. But just as he’s about to finish the quest, the game suddenly announces that its servers are shutting down... Yet the moment the game closes, he finds himself transmigrated to another world with the game System, along with everything in his storage, including a billion-something summoning scrolls. Huh? Ten years of hoarding, riches overnight. No worries about conquering another world? Oh, sorry, you’ve got it wrong. I don’t want to fight. I just want to be a quiet little hoarder...
