Through the Mirror World to the exit location, then leave the Mirror World, and then depart from the exit; this is a route exclusively for Hell's Return. Clearly, Little Drilling Wind also realizes this. Although Hell's Return needs to break Wu You's Imaginary Armor, the ultimate purpose is to head to The Land of the End and achieve final victory.
What lies in front of Hawkeye is the issue of priorities. Strictly speaking, leaving the Dark Forest without achieving the goal doesn't fit his plan, but the emergency society cannot accept this. For the emergency society, the Dark Forest is akin to having the advantage of time, location, and harmony. If Hell's Return can escape under such circumstances, coupled with the previous overtaking incident, even if Wu You can maintain the current state, it's hard to guarantee absolute safety.
