Amid Tao Yao's life-pondering expression, Zhou Li and Zhou Xun, along with the old scholar's bundle, fled into the room like a gust of wind.
"Everything's here."
Upon opening the bundle and seeing an abundance of treasures and raw materials, Zhou Li and Zhou Xun vividly enacted the fly-rubbing-hands gesture, then began to divide the spoils.
All these things had been pinched from the old scholar's home, such as the scalding lime mixed with spirit stone fragments, and the colorless, tasteless, high-strength laxative, among other items not available outside. If not for the old scholar's gallbladder inflammation which left him weak, and the pressure brought upon him by the appearance of the two Zhou Lis, these items would not have been so easily snatched by the Zhou Li duo.
As for why a teacher like the old scholar would have such things at home...
He had a student named Zhou Li.
Another named Tang Wan.
