I know what happened

Yeah... Actually no.

How could this be successful ? Even if you consider human as ressources, betting 3 heroes lifes and using 4 heroes on one front, even with necromancy it would have been a waste as it's also the heroes who killed the dragons and nothing was shown as they actually regain territory, more like they stop for a while attacks en one front.

One panel MC fight the necromancer (not a hero at all), yet a few panel later, "Necromancy is ok !".

She will use this super artifact on "whoever is sent without checking the qualification" ? The elf warn about the danger of using it at random. Before rania was actually listening to his advise... after the fact, but it's already after an instance.

Rania is the only one who ever actually reach the true mastermind, and while it's a Truth and is unable to speak about it, Rania is in for THIS fight, her student can go fight the remnant of the demon king. At least I can't see with how twist are "heroes" how the win would ever be possible without her power on that front.

How to allievate anxiety of the spear guy ? By saying him to raise disciple ? Seriously ? Ddi he not come for Chloé in the first place in the beginning to replace him ? 

Worst arc so far, very disappointed

What I am evn reading. Why force the plot that much while it was smooth sailing aside for the bone guy until this firld trip

Nop there is still nothing right in this chapter too.

Don't look so smug when a frail healer girl shoved you aside
