Death Prison was not unfamiliar to Ning Fan, having visited once before, making it naturally easier for him to know how to infiltrate.
Since Ning Fan's last disturbance here, Death Prison had suffered a significant loss, and with the appointment of a new Warden, its defenses were upgraded once again.
On the high walls, the faces of the cold-hearted Guardians were visible; they held loaded guns, and the slightest rustle would alert them.
But this first line of defense was not a big challenge for Ning Fan and Ouyang Feifei to cross.
Two agile figures gently landed on the ground, Ning Fan and Ouyang Feifei hid in the shadows; they were in Death Prison's garbage incineration area, which had the least surveillance.
Ouyang Feifei had done her homework before coming. Her knowledge of Death Prison was definitely much more extensive than Ning Fan's, not only because she had faced hardships here but also because she came well-prepared.
