Chen Heng did not reveal any flaws. He only left for less than half a month, which was not too long enough to arouse suspicion.
At the ruins, he used his phone carefully shrouded himself in fog from the beginning to the end due to security concerns so that no one could spy on him.
Based on the current situation, this security method was undoubtedly suitable, allowing Chen Heng to avoid a lot of trouble. To Chen Heng, everything around him was very stable, and there weren't too many surprises.
As for Lu Yao's side, although the specific situation wasn't clear, Chen Heng did make a call home. Lu Yao had already returned home at that moment, and there was nothing unusual about her.
