I'm mainly talking about Song Zhi, the mc's superior in charge of the research project in that other dimension world. We learn pretty early on that S class organisms (the native creatures of this other world) are highly intelligent insanly powerful beings capable of leveling an entire human base on their own. Also capable to miMC the human form and seduce humans into becoming their offsprings' incubators, alien style. We also learn that the neurotoxin that the humans are shooting at lesser dangerous creatures is only effective because it was taken/developed from the spine marrow of such s organism. So, how did the humans manage to get a hold on that material from such a dangerous creature they couldn't possibly subdue? Later we learn that Song Zhi almost killed an s organism, so we probably know where the spine marrow came from, but again how? Then, Song Zhi reveals his deceased fiance developed the neurotoxin they weaponized and she along with his former research colleagues were all cruelly killed as a revenge by an s organism he angered. He frames it like that: the s organisms are very proud and so powerful, they consider humans as ants and at some point he came across one, but angers it which led to the brutal death of his loved ones. Which is why he wants to kill said s organism. Pretty straight forward, untill you think about it and realize that if his fiance died, then the extraction of a bone marrow happened before that which means he possibly tried to kill it first. Song zhi laments in his thoughts that he won't be able to kill the s organism the same way he almost did before because it would never trust him again- this implies Song zhi was the aggressor, because why would an intlligent creature would trust another intelligent creature after he killed their loved ones?

It just so happens that the gong ML have hacks being an otherworldly powerful alien.

I just find it funny that author write a very strong character like Ymir but have to nerf him so hard just to make it hard for our leads and make them shine. If Ymir is healthy all along the story, there won't be much excitement hahahahaha. I just love his character so much even tho his exposure is less than Wu Yun lmao.
