Originally, Douglas wanted to go directly back to the Sky City laboratory. The old man was a research madman. In addition to the super Saiya kakarot borrowed from Locke, Douglas gained a lot in the ancient tree continent of soul.
Such as the living specimen of the eight winged angel yadehua, the weird soul specimen of the fifth level peak, and a variety of soul attribute materials
Roughly speaking, Douglas can lock himself up in the laboratory for 500 years in the future.
But the plan can never keep up with the change. Douglas is a wizard. At present, the world is ordered 412, and there is still 8 months to go.
