章 120: Investigation Team

"Teacher Cao, where have you been these past few days?" Mo Xiu immediately picked up the phone and asked."

The voice on the other end of the phone sounded a little weak.

"Don't worry about it. You'll be here tomorrow. I'm looking for me in my office. Let's talk about it. * Cough cough * Investigate firearms!"

"Good! I understand. You should rest quickly!"

Mo Xiu hung up the phone. From his voice, Cao Fenglin seemed extremely weak. Could it be that he had been too sad recently?

The next morning, Mo Xiu went to Cao Fenglin's office and knocked on the door. There was no one inside, so Mo Xiu could only wait at the door.

Not long after, two figures appeared. A stranger was supporting Cao Fenglin as they walked over.

Mo Xiu immediately went forward and supported Cao Fenglin.

"Teacher Cao, what happened to you?"

Cao Fenglin was still very weak. His face was pale and he was much thinner than before.

"Let's go in first!" Cao Fenglin said."
