The Formless weapon!

Rio suddenly noticed that a few more words have appeared on the piece of paper which he found before.

{If you are reading this then it means you have survived that potion. Congratulations you were able to survive even though the chances of survival were only 1 percent, indeed you have a very firm and strong will. I hope you will be able to achieve greater heights.} 

{I wish you good luck!}

.

Looking at the newly appeared words only one thing appeared in Rio's mind:

'you should have told that earlier! I could have been dead by now! I wonder how my father became an S-ranked with such a laid back personality, sigh~' (Rio)

If Rio had lost his consciousness he would have died immediately. That was a really dangerous thing but nevertheless he survive and there's a saying:

{If something doesn't kills you, then it makes you stronger}
