*Whooshh* As soon as an invisible wave erupted from Angus, Anna, who was sleeping near Angus, immediately woke up. She looks at Angus, who is still meditating in the lotus position.
Jayna and Ilgor didn't notice the change in Angus and are still recovering their exhausted mana. In the meantime, Angus didn't notice the invisible wave he released and kept stabilizing his dantian.
Unlike mana core, Dantian has a very different concept. Mana cores can be used as storage, main control, and manufacture of mana. On the other hand, Dantian is only storage for chi. As for control and refining chi could only be done manually by the user.
Chi and mana themselves are different yet also similar. If mana is calm and flows like water, chi is wilder and raging like thunder. Both of them are energy but have different types.
