Can someone help find the title of a manga i read a while back please. Its about a son left behind with the grandpa blacksmith because the dad went to war. Its split into 2 story lines, ones the dad, the other the sons. Grandpa gets killed by a swordsman and then son gets sold off as a slave in a gladiator arena style. Father comes home looking, finds out his dad or grandpa is dead and takes the half sword/ half scimitar?? Whilst father is looking he kills people along the way that are after him due to resisting the murim faction? Or whatever. Son gets pushed in a well by weak people in arena and ended up fighting an eagle? And finds a swordsmans legacy? Thanks a lot, much appreciated. This totally has been gnawing at my brain trying to figure it out. Looked on google, looked on hot manga and checked through the pages and cant find it.
