Zheng Tan had never seen that man before. The kindergarten was staffed almost exclusively by female teachers who had been selected through multiple rounds and some personal connections, making them relatively reliable.
Zheng Tan knew both teachers in Zhuo Xiaomao's class, and this man was certainly not one of them.
The management of Chuhua University Kindergarten was strict; strangers were not allowed in. The children here were all from the university staff, and the security guard, an elderly man, recognized most people. Therefore, it was impossible for an unfamiliar person to be let in by mistake.
Of course, all those measures were directed at people. They were useless against Zheng Tan, a special case. The walls and fences couldn't keep a cat out.
Zheng Tan jumped onto a nearby tree, watching Zhuo Xiaomao and the man.
