Chapter 549 Unnamed Affections

Hu Xiaobei slightly furrowed his brow when he heard their question.

"This… Master Xiaobei, is this question too difficult?"

"Or should we switch to another question?"

"Yeah!"

Seeing Hu Xiaobei frowning, their expressions changed slightly as they quickly spoke.

They knew the question they asked was indeed challenging, as over the years, they and many experts had discussed it but never resolved it…

Seeing them tense, Hu Xiaobei smiled softly and shook his head gently, saying, "It's not too difficult, it's way too simple! So simple that I don't even feel like explaining it to you."

"Sim…simple?"

They retorted, their mouths twitching fiercely…

They hadn't expected that the problem they couldn't solve would be the simplest kind for someone else…

Hearing their astonished retorts, Hu Xiaobei naturally nodded his head.

Soon, Hu Xiaobei began to explain the answer to the question.

After listening, they just nodded blankly.
