Mu Feng wasn't sure if it was his luck or not, he got Professor Ryuren's some documents and there were medical reports as well. There he discovered Professor Ryuren's DNA result.
One of Mu Feng's medical experts suddenly told him that Professor Ryuren's DNA seemed to be very familiar to someone. Mu Feng gave him permission to search through the recent medical records and after two nights three days of without sleeping searching, they detected that his DNA matched with Mu Lan's.
When the result was out, Mu Feng almost fell from the chair. He thought, 'Coincidence does happen in real life.'
After getting the result, he immediately took the decision of going back to Paris and coax his one and only sister. At that time, he really wished that he could become Mu Lan's related brother.
Who wouldn't want such amazing father?
Rich, scholar, loved his wife dearly, had a successful life, everyone admired him, had two amazing children; Mu Feng was really envious.
