Willian was undergoing the torment from Ax's training daily. It took him almost a month to Completely control his faintness. Now, no matter how strong Ax hit him. The man would be able to stay awake. The pain from the training has never resided. His body was now almost permanently numb.
Initially, Ax would beat him once a day. Then as Willian adapted to the torment the pain increased. The cruel instructor would appear twice a day. Twice became thrice and then it became a whole day. After beating him for a whole day, he gave Willian just one hour to rest and started to beat him again.
Willian would now be numb to his plowing and his body would fly all over the scenery. However, his eyes were more agile than before. He was able to see what Ax did. Despite standing in one spot the man could attack him from all and every angle. It was because the man was so fast despite his burly physique.
