During the day, Qin Gengyun, Qiu Zhihe, and Liu Su arrived early at the Moon Drinking Tower.
Qiu Zhihe set up the Wind Return Array in the copper mirror of the "Moon Charm" private room.
And taught Qin Gengyun how to connect spiritual power with the Wind Return Array, so that if Si Minglan used her charm technique tonight, Qin Gengyun could use the Wind Return Array to counter her.
The array's subtlety lies in the fact that if it's not activated, there won't be a hint of spiritual power fluctuation, making it completely undetectable.
Even if activated, it instantly seizes the target's consciousness, and even upon awakening, it feels as if just a moment has passed, making it extremely hard for the target to notice any anomaly.
After teaching Qin Gengyun how to activate the Wind Return Array, Qiu Zhihe left the Moon Drinking Tower with Liu Su.
Leaving Qin Gengyun alone in the private room to wait for Si Minglan's arrival.
