This is a great idea, a ok translation, and has stable updates... But are you kidding me? This more unrealistic than the extreme plot armor isekai protags' that are extremely lucky. I have only read 5 chapters and I am regretting reading the summary (I read this so you won't want to read it).
First of all no. No one will just go strait to ancient language when a new type of power comes in. Another thing, isn't it questionable how close it is to many korean and chinese novels and beliefs? Also wouldn't the sword, that destroyed the sun, be able to destroy the Earth even if it is a shard? After all, 1,300,000 Earths' can fit inside of the sun and such a sword should be able to destroy the Earth just by tapping the Earth. Also if the shards were smaller than I think the shock waves should be like an extinction bomb and would just vaporize all life of Earth. But hey, what if i'm thinking of it too realistic, after all, it's a fantasy novel made in korea. BUT JESUS IT IS STILL BAD AFTER CHAPTER 4. It just got so boring, after chapter 4, chapter 5 is just filler, and not even ok filler it's really bad!
This is the real review: (It is out of 5)
Boring (1 is not boring 5 is really boring): 4
Filler (1 is no filler 5 is a lot of filler): 3
Character's Stupidity (Same as the other 2): 5
This world makes sense (1 = a lot of sense, 5 = no sense): 4
After reading this I hope you understand and don't read it unless your like me and would just read it to post a bad review.
