Comments of chapter undefined of Inventors system

Then there is also something else I wonder about. Samael said that he couldn't beat them because he was severely weakened in this realm. that means that he would have been able to beat them in the higher realm. to begin with he was originally that strong that they couldn't kill him and only managed to seal him away. It was stated that he had recovered around 90% of his former strenght. even with his powers weakened in the lower realm, such a rebuff would not apply to the strength of his soul. how were they even able to destroy his soul. that part just doesn't make any sense to me. you should have described the fight in detail and explained what exactly happened there and how they managed to destroy his soul. I can't be the only one who is frustrated and can't figure it out :D
