After reaching the ventilation duct, Luo Fei and Zhao Donglai leaned against the entrance, one on each side.
The space inside wasn't very large, making it somewhat inconvenient for two people to crawl inside together.
So Zhao Donglai decided to act separately from Luo Fei.
One of them went inside, while the other kept watch outside.
The space inside the duct was quite stuffy. Although it was a vent, since it generally didn't extract air, there was no air circulation in this area.
Mostly, it relied on an external exhaust fan functioning, so the air here was not flowing freely.
However, within this oppressive space, Luo Fei could detect a faint scent of blood; there was no doubt about it.
The mysterious adept had abducted the person from right here!
After shining his phone's light and fumbling inside for a few steps, Luo Fei suddenly noticed some congealed bloodstains in the corner, which seemed to have dripped from Liang Deng.
