Xia Changhe

He is the father of Xia Lei and Xia Xue.

The household registration file shows that he was born in 1965 and will be fifty this year. He studied Culture and graduated from Hai-Zhu First Middle School. He joined the army after graduation and entered the Special Forces Unit in his third year due to hard work and excellent performance. He served in the Special Forces Unit for three years before retiring and there are no records after that.

Xia Lei could still clearly remember that 5 years ago, the same year his father disappeared, his body was very weak. His father obtained this bottle of medicine from who-knew-where. There were only 20 white capsules in the bottle and his father only let him eat one every month. The effects of the medicine were great - his body’s condition improved a lot after eating the first capsule. His father disappeared around the time he ate the 19th capsule, and the last capsule went missing.

Very often in the story, he appears at certain times, in very short intervals to assist Xia Lei or protect him when he is in trouble. Because regardless of his disappearance in the past, he still loves and wants to protect his son. The reason for his disappearance seems to be related to the AE Capsules and the organisation that's behind him (The CIA and the people who made the AE capsules), or that he was a part of in the past, and to protect Xia Lei and those around him, has decided to be on the run.
