He Feng and Li Tong secretly investigated for some days and found that the woman had been telling the truth about buying gifts.
However, after buying the gifts, they did not know where Wu Wei actually went.
Just the clue of buying gifts alone was not enough to prove that Wu Wei had a sufficient alibi for that day.
It could only prove that Wu Wei had arrived at the crime scene later that day.
However, until now, the time of death of the victim was still doubtful.
He Feng and Li Tong had been investigating this matter for nearly three days, but it seemed that someone was interfering with their investigation.
When He Feng returned home at night, it was already close to midnight.
Shao Xiang was carrying a basin and was about to go to the kitchen to pour some hot water.
The weather had been cold recently, and every house had a heater. The air in the house was hot and dry.
