If we choose this place, then as long as we are clean and make some false evidence afterwards, we might be able to provoke a conflict between the two sects. This way, we won't be so easily exposed. Even if we don't erase all the traces, they might think that the other party is making false evidence and won't suspect us at first." Zhao Hai said calmly.
