a couple years later the arc finds out and he's not to happy about it. But before the arc got locked up he had seen a crystal in the deep oceans that can bring people back to life. but it would be to dangerous for him to go alone. and the guard didn't know that his house was right above it
but the guard fell onto a floating island while falling into it. if that island wasn't there he would've fell into the hands of upper 1.the shadow king. So arc prepares to go there in 3 years and trains as much as he can. He starts learning more about self defense,speed and reaction time. he becomes stronger and stronger until 2 years later while training the water flow changes and he senses a strong power. The upper 6 had found him while searching for everest.
