Molds after molds were being carried over to Ou Yangming while he was responsible for modifying them with his Military Fire.
When the Military Fire spread and enveloped a mold, nobody could see his trick. In actuality, even without the fire as a disguise, those who had not achieved a thoroughly meticulous state in terms of the understanding of nature could not notice anything fishy.
Through constant hard work, Ou Yangming refined every mold.
Under the thoroughly meticulous state, the veined patterns of the rune on each mold completely matched the one in his memory. Moreover, each time he revised a mold, the floating rune in his mind became more solid.
As the rune became more solid, Ou Yangming also became faster at amending the molds. Toward the end, when his Military Fire wrapped around the molds, it only took a split second for the rune to be amended.
In other words, one breath was all it took for the mistakes in the details to be fixed.
