177 Blood Refinement

Each link of the wristwatch served as an amplifier from the next. Mana would be filtered and pulled into the identical first links near the two edges of the band, then amplified and sent to the next link. 

The second link would absorb the Wind Element Mana and filter it again, removing any irregular or damaged Mana Particles that would inevitably be absorbed in the first cycle.

Once the remaining Wind Mana Particles were fully filtered into the second link, the amplifying Runes would effectively double the number of Wind Element Particles in the link.

Twenty percent of the Mana Particles would become damaged from the doubling process, but those would be filtered out by the third link, which would double the Mana Particles again.

But how can the Mana Particles be doubled? Isn't there such a thing as the Law of Equivalent Exchange in this world?
