Returning to his apartment with a large package of materials from the self-serve supermarket, Chen Mu immediately buried himself in the hard work.
There wasn't any essential difference between the composition of a three-star power card and that of a one-star power card, except that it was more complicated, and more refined.
Still, completion of a three-star card required the involvement of perception. That wasn't any complication for Chen Mu by that time.
His first leap in understanding was making those twelve cards from the simple water world, and his second was making the tailless shuttle card. It had cost him a lot of effort to make that three-star card which had such a high level of difficulty, using up all of his savings to that point. But the benefits he had gotten from it were equally huge, and they raised his sights far more than one level.
