After roughly four hours, Arkhen had killed a lot of undead monsters.
Tier-1 Ghouls: 79
Tier-1 Liches: 123
Tier-1 Skeleton Kings: 167
The rest of his Undead Army was filled with Skeleton Brutes and Skeleton Knights.
The Tier-1 Ghouls were the strongest in his army.
'Alright, I am done for now,' Arkhen thought as he left the Undead Realm, and saw that it was already 1:02 PM noon. 'Hmm, they must be on the 3rd floor.'
Arkhen directly teleported to the 3rd floor from his bedroom and saw that everyone was training and learning.
Sierra, Haruna, and Ruchina were sparring against each other since they were the strongest. Luna was powerful, but not in terms of martial arts. So she was just observing.
On the other hand, Azela was teaching skill-related things to Zoe, Evelyn, Ellie, Makoto, and Dionne. Moreover, he also saw Grace, Katherin, and Isabella sitting on chairs behind Zoe and others.
