Well, Kain can't easily knock out by a single punch directly on his jaw, so Kai was forced to use the handle of his Dual-wielder weapon. By this, he made a sound that was enough to alarm the two remaining adventurers.
Luckily, they were not in their wits to figure out what was exactly going on. They just found out after 5 minutes had passed as they thoughts there was just a cat running around.
"Hey, where's leader Kain?"
A man that had a dark skin tone and bald head ran through the door, then asked the bandits after seeing Kain was not there.
"Oi! Did you notice Kain?!"
A man in his thirties laughed, "Hahaha! What are you saying? You and Kain enter the house at the same time. After that, he never came out even though I invited him to join us." He replied, then kissed the woman next to him.
Hmm... The woman in her fifties quite enjoyed this scene as this was the first time someone treats her like this despite her age and wrinkled skin.
