A few minutes before Chiko stopped the first training, Ferdy and Mark were actually on the zone playing against the tenacious - bamboo pole.
WHAPAANG!~
PAHK!~
WHAPAANG!~
PAAAAHK!~
With every kick, they send the ball at the upper tip of the bamboo and causing it to bounce back with its flexible rebound.
While both of them has no problem picking up the bounced ball, it was the slight deviation from their aim that caused the problem. The moment they missed hitting the center point of the bamboo pole, the ball would easily bounce away and they have no choice but to chase after it over and over again.
As a result, Ferdy and Mark are running around in circles while keeping the ball afloat back to the bamboo. This training cost them an incredible amount of focus and energy that they can barely keep up after the twentieth bounce.
Fortunately, that record was already from the past.
