Tengen was training you, even though you were tired, he kept training you like he didn't care, he told you too wield your sword 1000x and then he said:

"Now, 500x more."

Your eyes widened and you started too wield your sword but it instantly fell too the ground and you fell down too, as you were exhausted and you were sweating while gasping for air.
