Capítulo 640: 179: To get rich, first build roads!_5

Old Mr. Zheng nodded.

Dr. Xiaoran watched the direction in which the sedan had vanished and let out a deep sigh.

From the day she remembered things, Mrs. Zheng had been searching for her daughter. This search had been going on for over twenty years; soon, she was going to get married and have a baby, and Mrs. Zheng still hadn't found her hope.

Dr. Xiaoran turned back to the laboratory and made a phone call.

"Hello, Lala. I need a favor."

A pretty voice came from the other end, "What is it, Xiaoran?"

"There's something wrong with my detector here. Can you help me with a DNA identification?"

"Sure!"

"Thank you, Lala." Dr. Xiaoran continued, "Then I will bring it to you right away."

The person on the phone with Dr. Xiaoran is Zhou La, her college classmate and a very good friend.

Although Mrs. Zheng doesn't believe in others, Dr. Xiaoran believes in Zhou La.

Instead of waiting like this, it's better to let Zhou La do the identification first.
