Diabolos can communicate using Spiritual Power, but he can speak, and the only language he currently masters is Xia Country language.
Because Diabolos's power is given by the Tree of Human Essence, which also only understands the Xia Country language.
The members of the God Creation Group couldn't understand what Diabolos was saying, but the Spiritual Power emitted by Diabolos could clearly convey Diabolos' meaning to them.
A few members of the God Creation Group, holding their instruments, immediately recorded Diabolos's image and language using their devices.
The videos and audios would be transmitted in real-time to the database of the God Creation Group.
Diabolos is the only known Extraordinary Creature to Huaqi at the moment, and according to Xia Country's saying, Diabolos is the only "Demon."
Therefore, every move and word of Diabolos carries significant research value.
