For the 2017 season, Aui_2000 joined Team NP. They managed to qualify for The International 2017 before being signed by the Cloud9 organization. They were eliminated during the first round of the Lower Bracket by Team Empire.

For the 2018 season, Aui_2000 joined Forward Gaming as a coach. On July 21, 2019, Forward Gaming was dissolved; the roster was then signed to represent Chinese organization Newbee at The International 2019.
