It's Gu Ning, Right?

"A-Are your legs cured?" Zi Beiying asked.

"Yeah, they're fine now." K smiled. He felt lucky every time he thought of his legs.

"Who did that for you?" Zi Beiying asked again with curiosity, because she knew that K had tried many times in vain. The person who had cured K's legs must be the best doctor in this world.

Hearing that, K gave Gu Ning a glance, because he didn't know whether he could tell the truth or not.

Zi Beiying noticed that, and remembered what Gu Ning had done for her father. "Oh, it's Gu Ning, right?" she said.

K was struck dumb for a second. He was surprised that Zi Beiying got the answer at once.

"Yes, it's me," Gu Ning said.

"Since it's you, it's not too much of a shock." Zi Beiying wasn't shocked anymore after hearing Gu Ning's answer. She knew how unbelievable Gu Ning was.

K soon realized that Zi Beiying was also aware of Gu Ning's outstanding ability.
