In the play, physicist Ye Zhetai was criticized for teaching the Big Bang theory and assuming the starting point of time, which was leaving room for the existence of God. Ye Zhetai was not only betrayed by his wife, but her daughter witnessed everything at the scene but could do nothing. This is the most critical factor for Ye to contact aliens. Without this part of the characterization, there is no way to explain why Ye insists on contacting aliens. This drama is not completely based on the original work, but I think the changed parts are more international. Overall, I think this drama is very well done and worth watching.
