Armed Ascension

A high-level armed omnium engineer from the earth traveled to a different world dominated by magic and swordsmanship, but was judged to be a waste without magic source. Others rely on talent to cast spells. He relied on engineering to dismantle the rules. Others regard magic as a mysterious force. He used the magic circle as a circuit board, the magic stone as an external battery, the magic core as an unstable energy source, and the divine bone as an unknown core interface. The final route is not to "become a mage", but to find a path that is not available in this world: **Magical engineer + mechanism weapon + swordsmanship body control + five source weapon core.
