Chapter 58: National Mathematical Olympiad

"What is correct?"

The postgraduate was feeling puzzled. He took a step forward to take a look and was astonished. "This…"

It was only then that Feng Xingshen regained his senses. He anxiously stood up and put away the papers. Seeing his student retract his gaze tactfully, he heaved a sigh of relief.

The postgraduate was still in a state of shock. "It's correct?"

Feng Xingshen nodded.

He seemed to have recalled something and hurriedly took out his phone. He gave Xue Xi a call via WeChat.

It was late at night and the young lady seemed to be asleep. The phone rang for some time before it was picked up. The young lady appeared uncomfortable to be interacting in this way. "Hello," she simply greeted moments after answering the call.

Her low and aloof voice had a hint of sleepiness.

Feng Xingshen quickly said, "Have you sent the results of the proof to anyone else?"

She paused before responding, "No."
