Because Silver Fang was receiving 40% of the EXP, killing 561 Ghosts only brought Ethan 370,944 EXP. He was still at Level 22, with 462,982/500,000 EXP. If Silver Fang hadn't taken that extra 20%, Ethan would have leveled up already. But he didn't care in the slightest—EXP was easy to come by. What mattered to him was that despite the massive EXP gain, Silver Fang had only reached Level 10, though its power boost could only be described as terrifying.
