Chapter 179 No Costume

The physics teacher carried reading glasses and didn't understand the answer for a long time.

I went to other physics teachers to discuss it again, but there was no result.

In desperation, he had to call the guidance director for help: "Director, I have a problem here..."

After listening to the cause and effect, the teaching director sent a contact information: "This is the telephone number of the teacher who gave the question. If you have any questions, you can ask him."

The physics teacher got through the number, and after they exchanged WeChat, he took the steps and sent the pictures.

"Excuse me, teacher, how to change this problem?"

It took a long time to send a reply.

"Sorry, I'm so excited. I'm just going back now. May I ask which student's answer is this? I haven't considered this solution before. If I can, can I recruit that student into our physics department?"

The physics teacher was stunned. It was just an answer. Is it necessary to be so excited?
