It's still early.
Viktor decided to prepare the soldiers only to be able to survive, discarding the idea that they would be really useful in large-scale fights.
The soldiers already knew Viktor's "theory" that you had to kill the strongest of the monsters to get out of here.
It was the afternoon of the fourth day here...
This dungeon is gigantic, and unfortunately, the wild orc was just one more of its monsters. The boss was still unknown.
When Emma woke up, the family had already almost reached level 27, so after that, they made it easily.
Then, they explored the surroundings, encountering several different monsters.
In particular, beast-like monsters abounded in the area of the dungeon where they were. The golden ass chimpanzees gave them copious amounts of experience as they came in packs, and managed to get Viktor up to level 28, with the rest of the family having 80% experience towards this level.
