Rairen awaits his new student to return, in the meantime his devious plans make their way and weave itself in his brain. Everything was set he was going to make him a fine ninja, he is going to pass his will onto him. "Asura hmm.." he whispered his name, only ten minutes passed and he could hear the trunks falling and a sword slicing through the trees. A sand clock on the side of the rock was set to time the young shinobi's return. He somehow knew he would be back before time, Rairen knowingly channels chakra in the sand clock forcing the sand to run out early and faster.
He had approximately adjusted the clock 11 minutes faster than it was before, when the young student announces his return, Rairen looks at the clock and smiles. "30 seconds late... Its a shame, I expected more than that. Here is your task now, get back to work and use the rock I carved in the shape of bucket to fill water in it from the nearby stream, and wet all these logs that you brought. The rock weighs some extra pounds, make sure you fill it all up and not waste any water. All wood must be wet in another 30 minutes. Don't make me wait more than that. Any questions?" waits for few milli-second "Good now, go."
