Wait why did the mc kill his master I forgot

His master attacked him (he thought his master was trying to kill him but he made him immortal)

ok thanks

Why he made him immortal?

That's spoilers for the novel:






Mc is actually the vessel for a calamity god (i think thats what it was) and his master was just sealing the god so that it wouldn't take over his body but he didnt tell the mc anything so the mc had no idea and just thought his master attacked him and made him immortal out of hatred.

So by making him immortal the god would never take control of his body?
Alright here's the last question, did the MC in the end know all that truth? And why also did the father of ML make his son live immortal?

Spoilers





I didnt read the whole story only half of what is translated (a third of the novel, im still reading) and what i told you was spoilers i got from someone else but my guess is that probably so that another vessel doesnt appear to protect the rest of the world. I dont know tho thats just a guess. Im sure he does find out by the end of the story. Both those guesses are based on my experience reading other novels/manhwas also my autism super power predicting plot points and pattern recognition.
At one point i think i remember reading somewhere that the ml parents said that the mc was going to make a great friend/'hyung' to their unborn child, so im sure they made him immortal to stay alongside mc because they know how lonely a long life can become.
