This was the first time Su Man heard Su Ruhua mention Su Ruyu's name. The previous time Su Ruhua mentioned Su Ruyu's name was when she was telling him about what happened before. Su Ruyu was a part of the Su family and she had to be mentioned. Save that occasion, this was the first time Su Ruhua mentioned her name.
Was she, in the field of viruses, more capable than him? Su Man broke into a slight smile. That was rare. He had always thought he was the best in the field and could not be surpassed. He had never heard of anybody who was even more eminent than he was.
"Sister, where's second sister?" Su Man asked Su Ruhua. "I never heard you mention her."
