In the blink of an eye.
A month had already passed since Fang Yuan returned to the Original Timeline.
Over the past month, Fang Yuan and the Pokémon had lived relatively peaceful lives.
Even Mewtwo, whom Fang Yuan had expected to be difficult to handle, had been remarkably worry-free.
After arriving in this timeline, Mewtwo's first goal had been to defeat Mew.
That was also one of the meanings it sought in life.
And in order to defeat Mew, it spent nearly twenty-four hours a day meditating and training intensely above the Fang Yuan Research Institute.
It did not matter that Mew was unwilling to accept its challenge for now. Mewtwo itself was not confident of victory yet, so it chose to train in seclusion for a while first.
Mew was right here and could not run away. Once it grew stronger, Mew would no longer be able to refuse its challenge.
Mastering Mega Evolution on its own was Mewtwo's ultimate training goal at present.
And accomplishing that goal would undoubtedly take a long time.
Fang Yuan was delighted. Great, it seemed that until Mewtwo defeated Mew, he would not need to worry about this troublesome child for a while.
However, as Mewtwo's Trainer, Fang Yuan could not let it figure everything out entirely on its own.
He called over Rotom and Porygon. Combining them with his own understanding of Mega Evolution, he compiled the development paths for both of Mewtwo's forms and handed them to Mewtwo.
Mega Mewtwo X: Its development path was to use Psychic Power to enhance physical strength, evolving into a Psychic- and Fighting-type.
Mega Mewtwo Y: Its development path was to compress physical strength, strengthen Psychic Power, and push Psychic Power to its ultimate application.
Both forms required Mewtwo to fully master the Destructive Gene
