Feudal Japan

When a soul is trapped in minecraft and had to learn how to work around the Thaumaturgy which is in physical objects and when he mastered it and had even met others in the same position as him but they were already old so they gifted him their knowledge & Power that they have. Once he became the strongest in that minecraft world he found a way to get out and come back to his world with everything he had still with him from the old world.

So how will he deal with the hidden world of supernatural now that he can meet them. Would he still continue his research of Thaumaturgy or try to live peacefully.
