The man in the wheelchair was one of the representative figures of the philosophy of war, Sun Wu's grandson, Sun Bin.
Sun Bin came a few generations after Sun Wu. Since they both appeared at the same time in the wilderness, Gaia arranged that they were grandson and grandfather to avoid making things weird.
After he heard that his grandfather was living in Shanhai City, Sun Bin did not come straight away. Instead, he went traveling until New Year's Eve before visiting.
The old man beside him was the god physician Bianque from the Spring and Autumn period.
Bianque called himself a traveling physician, as he did not stay in one city. In history, Bianque and his disciples traveled four thousand miles around.
Under the guidance of the guard, Sun Bin managed to see his grandfather, Sun Wu.
The meeting between the two was certainly an amazing event.
When he saw that the young man was truly Sun Wu’s grandson, he did not dare to disturb them and left.
