6. The Unexpected Truth (Answer)

1. Huang Chuan's administrator knew that Li Yuan was going to move on Sunday morning, and he himself was not in the dormitory from Saturday afternoon to Sunday, so on Saturday morning, he notified the gas company to stop supplying gas to the two people's rooms. Then, in a room where there is no gas delivery, it is impossible for an incident of gas poisoning to occur.

2, the act of turning off the gas switch is obviously a pretense, not the murderer would never do it. At the same time, Nan Yiliang has a murderous motive.

3. The method is as follows: Nan Yiliang deliberately lifted the lid of the teapot filled with water and placed it on the gas at the lid of the liturg at the lid of the liturgy last night, causing the teapot water to overflow after Li Yuan fell asleep, pouring out the gas fire, and causing the gas to overflow. Later, while Li Yuan was asleep, Nan Yiliang used a rubber pipe to stuff the gas downwind window into Li Yuan's room and poisoned Li Yuan. The next day, he rushed out of the room pretending to find Li Yuan dead, simply touching the gas switch and leaving fingerprints to prove his testimony.
