Song Lili already had a plan in mind when they bound them with hemp ropes.
Besides the dagger, she also had a radio device hidden in her underwear, which was uncomfortable but luckily foresighted for situations like this.
She tucked the dagger and radio device into her sleeve, flushed the toilet, pulled up her pants, and exited the bathroom.
While waiting for Shen Lingxi, she surveyed the surroundings.
This base was at best a temporary military base, adequate only for carrying out tasks and providing a foothold during actual combat drills.
A room for holding prisoners was adjacent to a small, square house, through whose window one could faintly see Zheng Caisheng handling the weapons on the table...
Those were the guns and cold weapons taken from them.
Song Lili had two objectives for leaving her room: to deduce the location of their confiscated weapons after observing her surroundings and to retrieve the hidden dagger and radio device.
Luckily, she achieved both objectives.
