From the start, the whole situation was in such a way that there were traps everywhere for Lith.
Even if he had great comprehension skills, he was bound to mess up since it was a setup which was almost out of his capabilities.
Lith may have ended up doing everything correctly, but this wasn't a life and death scenario where he was motivated or forced to give it his all.
Mayzin's punishment wasn't light when Lith messed up. The push-ups took every inch of energy from Lith and exhausted him to such a degree that he wasn't able to move even a millimetre by the end of the last repetition.
During his push-ups, Mayzin, while sitting on him, explained the things he had missed out severely and lectured him.
In the start, he didn't bother to check the surroundings he was in and also the pursuers. It was important to know about the surrounding area and why the people were there at that time and for what reason.
