"Come inside, it's cold outside." The security grandfather stood at the door of the security office, with a smile on his face, and urged Su Xiaoli with his mouth.

Su Xiaoli lowered his head and silently walked into the security office.

The security guard closed the door of the security office and continued to stand at the gate of the kindergarten, waiting for the students in the kindergarten to get out of school.

After a while, after the children in the kindergarten were also picked up by their parents, the entrance of the kindergarten, which was still lively, suddenly became crowded.

Su Mu hid behind the big tree and observed secretly.

Not long after, the teachers seemed to be off work, and they walked out of the kindergarten one by one, said hello to the security guard at the door, and punched the card on the fingerprint machine, and left.

The sky gradually darkened, and gusts of evening wind blew, freezing Su Mu couldn't help but shiver.

He glanced down at the time, it was half past four, and all the children in the kindergarten had already finished school, leaving only the children whose parents came to pick up later, and they were still in the security office.

The last time he came to pick up Su Xiaoli, it was almost five o'clock, and it seemed that there were no more children in the security office at that time.

Su Mu pulled the collar of the down jacket on his body, put his hands in his pockets, and continued to wait behind the big tree.

At around five o'clock, several parents came one after another to take their children away.

Su Mu folded his hands and counted them, and now in the security office, counting Su Xiaoli, there should be only three children left.

It's almost time to act.

He walked out from behind the tree, ran all the way to the door of the security office, and reached out and knocked on the door.

"Who?" It was still the security guard's loud voice that sounded inside.

"I'm here to pick up Su Xiaoli." Su Mu stood outside the door of the security office and said loudly inside.

"Oh, here it is." With the voice of the security guard, the door of the security office "clicked" and twisted open from the inside.

"Hello grandpa." Su Mu stood at the door and greeted the security guard very politely.

"Hello, hello, come in." The security guard nodded at Su Mu with a smile and led him towards the inner room.

As soon as he entered, Su Mu saw Su Xiaoli sitting next to the electric heater.

How's it going?

Su Mu asked Su Xiaoli with his eyes.

Su Xiaoli pursed his lips and nodded lightly.

Su Mu's hanging heart finally let go, and he beckoned to Su Xiaoli and said, "Xiaoli, go, go home." ”

"Hmm." Su Xiaoli nodded, hugged his schoolbag, jumped down from the chair next to the electric heater, and threw himself at Su Mu.

"Goodbye, Grandpa!" Su Mu took Su Xiaoli's soft little hand, and after saying something to the security guard, he dragged her away.

"Goodbye, be careful on the road." The security guard still smiled at the two of them.

After Su Mu came out of the guard with Su Xiaoli, he heard that the door behind him was locked again.

"Brother, I recorded ......" Su Xiaoli took out a voice recorder from his jacket pocket and handed it to Su Mu and whispered.

"Shhhh......h

"Brother??" Su Xiaoli looked at him a little strangely, lowered his voice and asked, "What are you going to do......"
