Cui Heng knew very well that he was a so-called "transmigrator". Before he transmigrated to this world, he was still thinking about his imaginary wife. Normally speaking, his source in the River of Time should at least trace back to his life on Earth.
But in reality, that was not the case.
There were no traces of Earth in the River of Time, nor were there any traces of him transmigrating from Earth. Through the River of Time, he'd appeared out of thin air in the primitive forest.
If he continued looking, there would be no traces related to him.
It was as if the 20 years he had lived on Earth did not exist at all.
It was as if it had been completely erased without any traces.
There was not even a trace of Earth itself.
It was the same for the solar system, the Milky Way, and so on.
"This is probably related to the reason why I transmigrated and obtained the System." Cui Heng thought to himself and temporarily suppressed this doubt.
