Fernando was just a homeless man, an insignificant character. His escape would bring some trouble to Peter Lee, but it was nothing compared to other troubles.
It was conceivable that Peter Lee was likely to let go of Fernando and focus his energy on pursuing Zhang Zian.
Not only did Zhang Zian destroy the power supply system of the slaughterhouse, but he also set it on fire and even took away a laptop. So, it was obvious that Peter Lee was absolutely in a hurry to catch him.
Because of last night's rain, Zhang Zian's smell was washed away by the rain. Peter Lee didn't know where he would run to, but he must have thought that he would escape the forest first and then go outside to call the police, so he would place a large number of troops outside the nearest town to block him.
