His True Self?

When Davis married Evelynn, he was 18 years old. From that time, two years had passed. His current age had reached 20.

In the past, as Tian Long, he had transmigrated into the 3-year old little Davis and lived for over 17 years which makes his current age 20.

Reasoning like this, the current year should be 2047 since transmigrated in 2030 and lived as Davis for 17 years, but differing from his calculation, it's 2050.

What exactly happened in those remaining three years? From the year 2047 to 2050?

'The spatial tunnel!' 

He could only think of this event!

He abruptly realized that he could've been in that unstable spatial tunnel for over 3 years but couldn't confirm it in reality since his sense of time, touch was all robbed from him when he was in that so-called Transmigration Stone with his soul form.
