Mohan's instinct which led him to instruct everyone not to kill Wang Yu Yan stemmed from the plot. In the original timeline, the latter was the one who indirectly informed him about the plan.
Unfortunately, this time around, the female lead was the one who captured Wang Yu Yan.
The villainess was careful but when the elite squad comprised of nobles were provoked, they dropped their wariness from being too deep into enemy territory and just retaliated with all they had. Nuwa had even eliminated almost a hundred soldiers guarding the command center of the south, further throwing everyone there in a mess.
When the operation ended, Mohan's squad was divided. Contrary to what was planned, four of them managed to come out of the southern region. Mohan was one of them since he was the commander of the team imprisoned several days prior.
