Zheng Yuandong walked lightly on the street, following the route Qing Chen had planned for him. He met two Parent Association members at the designated location and then traveled together.
These two members were meant for the use of the Key of Gate.
One would have sufficed, but to be safe, Qing Chen arranged for two.
In theory, the best way to use the Key of Gate is to carry the door with you, ensuring a stable arrival at a given destination.
However, in a city where experts are under surveillance, carrying a door to visit a scientist might seem somewhat disrespectful to the Deer Island intelligence agency…
It would also make one look a bit foolish.
Luckily, the Parents' Meeting has many members, and in every city, there's a group of Time Travelers; this is the advantage of having widespread connections.
