Chronicles of the Heavenly Demon신마경천기

Do you happen to know the name of this manhwa? it's very similar to the two you mentioned, this is what I can remember: The beginning starts with a man who has cancer and after looking for all the methods, he finds that there is no cure, he decides to use unconventional means to cure his cancer with meditation, although it has no effect, he continues to meditate, until one day near a lake, he ends up falling (or was it suicide? I don't remember) and is sent to another world. In this new world he discovers that his meditation technique is not only eliminating cancer but also strengthening his body, at first he has difficulty surviving, but over time he starts to fight with orgros (goblins) of 3 meters in height. using only (something like a piece of cloth with a rock, then you spin very fast and throw the rock), even find women who were kidnapped by these ogres (goblins) and save them.

yea i read all chaps available but he didnnt killed the mage
