Murder motive

Last night, it was Ren Xiaosu and the Great Hoodwinker who were keeping watch. In the first half of the night, Ren Xiaosu was very sure the statue had not appeared in the campsite yet. He found the Great Hoodwinker and asked, "You didn't hear anything during the second half of the night?"

"I really did not." The Great Hoodwinker shook his head. "Even though I joke around a lot, I'm still very careful when I'm outside. I couldn't possibly be unaware if someone had carried such a huge statue into the campsite. To be honest, I didn't even see anyone moving around last night."

"Where were you keeping watch?" Ren Xiaosu asked.

"Over there." The Great Hoodwinker pointed to the three o'clock of their campfire.
