"I realized then that something was off. How could you coincidentally find someone in your own bathroom?
"I told a friend about this, one of Yuan Haotian's co-workers. After hearing the situation, he became scared too and advised us to be more cautious. He even suggested reporting it to the police.
"We wanted to avoid causing unnecessary trouble, so we thought we could wait a bit longer. If Yuan Haotian kept this behavior up after some time, we would then consider reporting it to the police.
"But before we knew it, he had burst into our home holding a knife, and killed Zhang Shengli and Cao Deren," Li Shu said, his expression sorrowful. "As for how I managed to escape, it's because I had just returned home from a night shift when the incident happened. The moment I walked through the door, I saw blood everywhere.
"Both of my friends were lying in pools of blood, and Yuan Haotian was standing near them with a knife in his hand.
