Another important point is that Lin Yi can choose the time point to return with the system.
This allows everyone to unknowingly believe that he has always been by their side.
To exaggerate a bit, if he lives in ancient society for a year or two and then directly transmits back to the time point when he just left, they would think he just took a short walk.
Or while they're watching TV, he suddenly disappears, and when he returns, they may not even realize it.
Of course, for safety's sake and considering everyone's feelings, Lin Yi won't do such a thing.
He won't disappear in front of them.
After all, Lin Yi always believed time moves forward. If he leaves, while he's living in ancient times, time will continue here as well.
In this scenario, they would also fall into a state of fear, even though he can return to this point in reality. In his absence, they will experience helplessness, panic, and even sadness, which is something Lin Yi doesn't want.
