The thing is Ajax didn't know exactly how severe the penalty would be; however, Ajax was not worried too much about it.
For him, as long as he could live, he would be willing to pay the penalty no matter how costly it would be.
Also, Ajax felt that dying in his current situation would give him the least penalty and moreover, since his body would be intact, Ajax felt that he didn't need to put in extra effort to create a new body.
Nevertheless, Ajax could tell that it wouldn't be an easy task to enter his own body.
Anyway, Ajax didn't have a single clue of how things would turn out to be in such a situation where he would die and return to the Soul Nourishment Tree in his soul form.
To know more about it, Ajax had to die and figure it out for himself; however, why would Ajax kill himself for such a thing when he had a lot of things pending?
'Damn it…this b*stard is much more cunning and stronger than I thought.'
