章 379: Jian Xi Arrived

Hearing this, Teacher Yun was stunned for a moment before he looked at Cheng Zihuai. "You?"

These questions were difficult for ordinary third-year students of Yun University.

A third-year student from Hengde could solve it??

At this moment.

A student from Nili University waved casually and smiled lazily and confidently. "If anyone knows how to do it, you can go up and do it."

Teacher Yun's expression did not look too good and he could only nod in agreement.

"Then you can go and try."

In front of everyone, Cheng Zihuai went up to look at the questions for a while, before his lips curled up and he picked up the chalk on the table.

Everyone's eyes were curious. They wanted to know if this person could really solve it.

At the same time.

Pei Yunge received another message from Jian Xi.

[Jian Xi: Teacher, where are you now?]

Pei Yunge looked down and replied to the message.

[Your school's conference room.]
