Challenging the Devil's Training.

  The sixth day of training was still as brutal as before.

  Looking at the bruised and battered duo of Su Yun and Barack, Mark used a phrase.

  "This is an inhuman challenge! No one would be willing to fulfill such a challenge except for these two stubborn perverts of theirs!"

  Leverkusen's u19s were, likewise, shocked by the duo's performance.

  They also choose programs to train with the two during their time.

  But even this scaled-down version is hard to get all the way through.

  And in the face of such a challenge, Su Yun and Barack all silently took out their killer weapons.

  Su Yun's killer skill is his tenacious fighting spirit, and the more difficult it gets, the more his fighting spirit flourishes!

  Barack, on the other hand, relies on his strong willpower to stay the course as long as he doesn't fall!

  And so it goes, although every training task is incredibly difficult.

  But the two never stopped.
