After resting for a day, they still didn't dare to stop. The next night, everyone disguised themselves and went out, heading straight for Song Yi's home.
They couldn't act conveniently during the day and could only wait for night. Otherwise, killing Song Yi would be hard to explain—what Fusang person knew Wu Yunfeng, who knew what Song Yi had done?
Looking for evidence would be too slow; there simply wasn't time.
Unfortunately, they ended up with nothing. Song Yi was gone—not missing after they killed Wu Yunfeng, but already disappeared the day before they captured Wu Yunfeng.
Song Yi's wife was also searching everywhere for him. He had stayed out all night before as well; men in officialdom often went out drinking and spent the whole night in a brothel, which was common.
But Song Yi had been gone from home for three days and hadn't gone to the place where he was supposed to be on duty. There was no way his wife wouldn't worry.
