Wrong Assumption
Noir furrowed his brow and stated, "I'm going out."
The situation outside seemed to worsen with each passing second, and he needed to assess what was going on. Alas, how could the other three stay put inside the room? They were eager to go out and inspect the scene too!
While Jin Jiuchi purely wanted to join in on the fun and Gu Luoxin intended to follow the Great God to see if there's anything he could help with, Shen Nianzu's line of thought was more practical and professional. Since Noir was not an outsider, of course someone from their team had to go out and investigate. Choosing Jin Jiuchi was not an option because the risk factor was too high – hell, who could expect what kind of shenanigans the man would get up to out there?! – so he could only choose between himself and Gu Luoxin.
