Zhao Yu didn't believe in prolonging one's life through unorthodox means. The person who created the Seven Star Hanging Coffins must have been a fraudster like Master Zhang.
He figured that, if the person to which the birth data belonged was indeed beset with a terminal illness, this person was probably already dead by now!
Therefore, they shouldn't limit their search to only those who were still alive, but should also take deceased persons into account.
If there was indeed a person who had the same birth data and who had just recently died from a terminal illness, then this person must be closely related to the case of the hanging coffins!
Zhao Yu heaved a sigh of relief. After going to so much effort, he finally had a lead of some sort.
