Honestly if the time dilation is proportionately slow in the "game" world while he is in his normal world then each month is spends outside of the game is only an hour passing by in the game, so he should have plenty of time to recover and still be able to warn his brother of the traitor.
@degenerateafro Yeah. Author added that detail in nice and easy.
I'm excited for future chapters. The plot device with the two differing worlds connected with the MC and the fact that the 240:1 time ratio applies to whatever reality he's currently conscious in is great. It allows both worlds to remain relevant to the story, considering his status transfers.
Now he can train in dungeons on Earth, level easy because rank separations are more detailed (E-rank dungeon will mainly only have E-rank monsters etc) while supply of enemies is also high.
A month in either world is just 3 hours of unconsciousness in the other (should be). I'm sure he can level fast to save his brother.
After eating, this man better pick up the vr machine and get back to the war! (Tho, I guess he's got plenty of time to do that... and I wanna see more of Leader Choi, lol) I just want his bro to be okay! (,,꒪꒫꒪,,)
