Compared to when they came silently and suddenly charged outside the Holy Land, Chuling and Yuan had caused a relatively large commotion when they left. When Chuling and Yuan left, they charged forcefully into the cosmic tunnel ruled by the Muyas. They directly broke through the defense fortress of a cosmic tunnel and disappeared.
And the information Qiao An received was that several of them had traces of being broken into. Qiao An organized a human search and finally found a strong energy fluctuation remnant on one of the planets. She could basically confirm that Chuling and Yuan had left this planet through their own methods.
In that case, they could confirm the reason why there were traces of intrusion on several planets.
Chuling and Yuan must have made some arrangements on a nearby planet. They would be able to arrive at the Holy Land in half a day if they wanted to kill their way here next time. There was no need to go through so much trouble like this.
