According to Xun Guilan, as per what Yan Chuan and Cheng Fengxiao learned from the Star Stone exploration, this 'Star Stone' not only requires 'charging' for two months to make a round trip, but also, during the 'shuttle' period, the 'Star Stone' cannot be charged.
Only after returning from the Mountain and Sea Realm and the Star Gate is closed, can charging continue.
Moreover, the 'Star Gate' can only be opened once for a maximum duration of two months, which means Cheng Fengxiao or Yan Chuan can stay in the Mountain and Sea Realm for at most two months. Once the time limit is up, they are forcibly sent back.
"Opens once every two months."
"Can stay for a maximum of two months at a time."
That's alright!
This way, over a year, they can stay in the Mountain and Sea Realm for half a year, which is sufficient.
