This is canon to the series of Tomb Reboot,but with a little change.

Pangzi came to the Wu household to ask Wu Xie something,but as he entered the house,he was met with a literal little copy of Zhang Qilling,or a child version,something like that.

He was dumbfounded and frozen,just looking at the little version of Zhang Qilling.

Then the actual Zhang Qilling approached them and that startled Pangzi out of his mind.

Skip to when Pangzi,Wu Xie,Zhang Qilling and the version of Zhang Qilling settled down.

Pangzi was staying a bit further than the two Zhang Qilling's,a bit near Wu Xie as he waited for Wu Xie to explain what the hell was going on.

It was really funny to see such a sight.The little version of Zhang Qilling staying right near the actual Zhang Qilling,mirroring his pose and expression and everything.

(You're Wu Xie)
