"Are you guys tired...do you need a break" Jake shouted.
"No Sir" all the students shouted half-heartedly.
All of them were sweating despite the cold weather, the training they were undergoing was simple basic training with Ki but the duration of the training was the problem.
They were divided into two groups and heavy rocks were placed at two ends, each group formed a straight line and carried the rock to the other end.
While the first group was carrying the rock from the left to the right, the second group was returning the rock to the left side and they had been there for almost an hour.
The problem was that the rock was too heavy to lift with normal strength, so the students had to use Ki in order to lift the rock.
"This is just basic training, you are going to be future swordsmen, so this is essential" Jake said from his chair.
"Sir we have been doing this for an hour now, should we rest a little," a boy said.
