Qin Feng reckoned he should not be too full of himself when he recalled that the Emperor Knight was at F8-tier.
He reminded himself not to evaluate the current situation based on his past experience as an A-tier warrior. Emperor Knights were a formidable foe that was still too difficult for him at his present state.
Qin Feng loosened up a little after he thought it through. 'Getting stronger should be my priority now.'
He worked relentlessly the next few days to exterminate as many F-tier zombies as possible. Nonetheless, the invasion did not show signs of slowing down.
Qin Feng had indeed become stronger. He was currently as lethal as an E-tier fighter. Both the number of zombies killed and his points increased exponentially as the days went by.
