The team left Shang Chi after they cleaned the evidence that a massive war took place in Liu Kai's hometown.
The numerous buildings and edifices that Medivh guarded while Liu Kai was in deep sleep were almost flattened.
The shattered school buildings that prevailed during the Great Catastrophe and weren't protected could not stand any longer, crumbling like a sandcastle before they left.
The shabby building where the scouts fought fell and was shattered into massive clouds of dust.
And the apartment complex where Liu Kai lived before buried the graves of Liu Kai's pets in the open space at the back of the building.
Liu Kai could not help but feel troubled about it.
He thought that he wouldn't have any attached emotions in his hometown since his memories there weren't so great but he lingered more than he expected before they left.
Most of what he reminisced was about his alone time in his room, reading tons of various novels.
