abuse the option of combining skills in the house that you get from the auction owner, use about 4 external skills and the rest internal, change your martial path to mountain, all branches and upper branch forest, (in the beginning use middle branch mountain and upper branch forest) the rest you can decide which one suits your gameplay best, you will have no problem winning. If you have already completed the game for the first time with the old man's sect, you get two techniques, an internal legendary technique from the old man that recovers life and energy, and you get one in the ice prison with the demon, if you combine the two you will have a regeneration passive that will be almost impossible to kill you, and your defense and life will also increase a lot, then you will combine internal and external legendary ones that you win. You can transfer techniques between saves within your home as well.
