Implanting a perfectly replicated consciousness into an unclaimed body for the management of world nodes.
This is a convenient management method provided by the Black Tower for node owners.
Besides managing the node world, the clone also undergoes 'training' that aligns with the characteristics of the node world.
When the original consciousness descends into the node world, all the memories of the clone are transferred back to the main consciousness, including the experiences and insights of these years, and even the sensory memories of certain details.
This is one of the benefits of owning a node, equivalent to having a clone synchronously training.
...
This is also the case with Han Dong.
When he intervenes in his own node.
First, a flood of memories rushes into his brain, and he also envisions the image of the Egyptian princess, of course, what sees the princess is just Han Dong's consciousness... the actual body has been isolated in the Black Tower's unique space.
