Originally, he had thought that he would not release this state so soon.
He had thought he would at least save it for the last ten days.
Who knew that the summoning ability of the Lord of Hell would be so difficult...
Then, the remaining Lord of Hell's evil spirits ignored all of its attacks, so he only needed to use a single reversal skill to slowly wear down their health bar.
Or maybe...
It was also fine to let the Boss burn all the mana he had to summon the hell legion.
In any case, this guy couldn't farm for himself and could have his mana drained by Lin Ye's reverse skill. Summoning his army and casting curses consumed a lot of mana too, and the words "if you target my mana, I'll die" were written all over his face.
Of course, Lin Ye could also use a Duel Invitation to drag the Lord of Hell's evil spirits into the duel space and kill it in a fair and just duel.
In fact, he had done the same.
