Even the butler was taken aback. For a moment, he couldn't grasp Tong Rao's reasoning.
He wasn't surprised that Tong Rao would hide the possibility that Gu Yang and Tong Wan were mother and daughter. Their strained relationship meant Tong Rao would likely prevent Tong Wan from finding her biological daughter.
But why fake a paternity test? Tong Rao only needed to conceal their connection.
Noticing the butler's confusion, Tong Rao explained, "Even though Gu Yang shares Tong Wan's blood, she is still a Tong family member. She has a right to be considered an heir."
The butler asked, "Then what about the real Eldest Miss?"
"Investigate her," Tong Rao said coldly. "The head of the Tong family has always been chosen based on capability. If she surpasses Gu Yang, then Gu Yang will serve as a means for her to hone her skills. If she proves to be inferior, she will only be a stepping stone for Gu Yang."
