I'm in Ultra, I Use Kemika to Collect Monsters

The protagonist Ye Bai, male, likes the setting of Gecha Deli Kemi very much. He bought some Khemika online. He died unexpectedly on the way back from picking up the courier. When he came to the Ultra World, the Khemika he bought came with him and got a system. (The protagonist will go to a non-Ultra world, but the length may be relatively short, and the heroine is to be determined) Newcomers, don't comment if you don't like it.
