The best arc is the next one, when he relives life’s of people who died of terrible causes like starvation just to master martial arts technique. I still remember story about children eating mud cookies and pretending they were real food because they had nothing to eat, also tragic story of his master. Next arc is amazing but also heart wrenching

the demon lord arc will rly one of the best arcs in this manhwa for me. i think it rly highlights most if not all of the best and worst aspects of his ability. how he is able to save all those ppl bcos he doesnt fear death but then it takes a toll on his mental stability. and the frustration when things dont go as planned despite suffering and enduring for dozens, maybe even hundreds, of years. and to have no one realize the gravity of your sacrifices... im rly glad he has the sword emperor and that somehow, at the very least, the tower recognizes his efforts. istg this man kim gong-ja has my utmost respect.
