Swallowed Star: Lord of Eternity

Having been reborn, do I still need to comprehend the laws anew? You say you need energy to achieve immortality, which means there's no bottleneck to it. This is a knowledge-based rule; do you want to start over? Damn, that's outrageous!

An ancient being hundreds of millions of years old can't even build the most basic spaceship by hand? Doesn't it even have any secret techniques? Is it really that useless?

The first major flaw is the unreasonable arrangement of human and monster strength in the early stages of the Great Nirvana. Only two years into the Great Nirvana, you're telling me that humans like Hong and Thor have already broken through to the planetary level, with over a hundred War God-level beings. This is highly illogical. Human and monster evolution couldn't be that fast.

So far, aside from not quite resembling an immortal being, there seem to be no major flaws.

An immortal being has no prestige whatsoever.

I remember that foreign woman was very vicious in the original story, so why was she chosen as the female lead?

The author's writing is great, but there's one problem: aren't planetary-level beings supposed to fly? Why is the protagonist always running?

Damn it, I thought I could finish watching it, but it turns out I'm a complete idiot.

This book was very well written; it's a pity it was abandoned.

I've read thirty chapters, and this is a harem novel? The protagonist wants to sleep with every girl he sees, and someone who's lived for hundreds of millions of years can't even control his lower body? Author, are you kidding us?
