Elena had already given Dalia and Eldriana their assignments for the whole week, so she had that much free time and she was also planning to completely crush these heinous criminals way before that time limit. But for that to happen, she needed to involve her alter ego of Carmelia and she was also going to introduce a second alternate ego named Mio. Mio was going to be Carmelia's teacher and also a powerful individual over level 700.
With this lineup and a little bit of cheating with her real powers, Elena was planning to end this whole thing in a day or two. She had no intention of wasting time and putting more children at risk.
...
As soon as she made the decision, Elena created two clones and told them to enter the city officially. As for Mio's identity, this time she directly created a fake identity which was so perfect that no one could judge it to be fake. So that problem was easily solved.
