At the 2018 Megaport Music Festival, Chthonic performed another new song called "A Crimson Sky's Command". Chthonic's eighth and most recent album "Battlefields of Asura" was released on October 10, 2018. In December 2018, Chthonic was unable to perform with Cantopop singer Denise Ho in Hong Kong since their work visa application was rejected due to domestic security reasons. The band ultimately ended up performing the song "Millennia's Faith Undone" remotely via Facebook. Thanks to Taiwan's success in handling the COVID-19 pandemic, the country authorized a return of the Megaport Music Festival in March 2021, organized by Freddy Lim and headlined by Chthonic, with 100 mostly Taiwanese rock bands.
