Anna had stayed in the Federal building since the end of the city defense battle. One of the main reasons she hadn't returned to the Genetics College was that the terrifying power displayed by the God of War Peter during the battle had shocked Anna.
She wanted to surpass the God of War Peter and become the Genetic God of War that protected mankind. According to the cultivation plan of the Genetics College, it would take at least six months for her to reach the level of the Genetic God of War. Furthermore, this was only the threshold to become the Genetic God of War.
If she wanted to continue improving her strength and reach the level of the God of War Peter, the amount of time she would need was unknown. This was something that Anna could not accept.
