According to Si Huang's memories, Qin Fan did not die at this time in his previous life, so logically speaking, he should not be in danger. In fact, if he did not care about his teammates now, he would indeed be safe.
It was just that Si Huang did not blindly believe in the rules of everything that happened in her previous life. One had to know that from the moment she was reborn, everything would change. No one knew if Qin Fan's fate would also deviate.
She didn't want to ignore everything and only hear about Qin Fan's death. She didn't even know how he died and her body couldn't be found. She also didn't want her actions to harm him.
The former could not be changed, but the latter had the opportunity to change. Hence, Si Huang made a decisive decision to join Qin Fan's circle and pay attention to the contents of his mission.
