The telepathic bond between Xu Chengzhi and his sister awakened when they were very young.
Initially, the power was weak and not very special, but as they grew older, their abilities strengthened, allowing them to communicate telepathically over short distances.
This "short distance" wasn't just a few meters or dozens of meters, but tens or even hundreds of kilometers!
Of course, compared to modern technology, this ability seemed to have little utility, given that the Star Net allowed instant communication over hundreds of light-years.
Thus, when their family learned of the siblings' abilities, they didn't pay much attention to them.
Aside from short-distance telepathic communication, there was also long-distance mutual induction.
Even if in different star clusters, they could sense each other's presence!
After Xu Chengzhi disappeared on Tampas Star, his sister Xu Yuanyuan firmly believed her brother was still alive.
