His plan to become a hunter when he reaches the seventh transformation is still on track.
Not only will he be able to use that identity to acquire the force diagram needed to reach the tenth transformation, but he will also be able to get the powerful weapon and defensive artifacts he needs to bridge the gap between him and the second mortal coil.
So it is a must for him to become a hunter.
After making up his mind, he ruffled Ruff's head and told the dog, "Ruff, we'll be going hunting soon. You have to bring your A game. None of that sloppy performance that you showed when we went hunting for deer."
Ruff looked up at him and barked. He didn't understand what Arthur was saying, but he was eager nonetheless.
Ruff is also at the seventh transformation of the first mortal coil. His progress is not due to hard work because what Ruff does most of the day is sleep.
