After entering Sewer 99, Lin Wu initially spent 20 seconds surveying the blueprint, before moving quickly forward with Wai, relying on memory after confirming he couldn't understand the blueprint. Minutes later, they arrived at a landmark lit up with a bright sign, where they encountered eight zombies. Lin Wu took down four with the Silencer, Silent Night killed two, and the last two were disposed of with the Wind Stinger.
Leaving the heap of zombies behind, they moved on. Wai's head emitted specks of Starlight and a series of bows, which looked eerie rather than endearing in the dark tunnel. However, the faint light alerted Lin Wu that Wai had entered an alert state; its head turned to the side, exuding hostility.
