Liu Chen actually knows very well in his heart that if it's a normal weapon, it can be enhanced by spiritual energy, and then improve its grade through energy enhancement, as the saying goes, "turning the rotten into the miraculous," that's exactly what it means; if a block is enhanced by origin energy, it could be more formidable than many weapons.
But the Yin Dragon Great Sword has already reached a very domineering level. Even without any enhancement from origin energy, its power is already formidable, so adding origin energy is not very impactful and even unnoticeable.
"That's not the case, some weapons reach a level where energy enhancement is inconspicuous, maybe your origin energy is not even as strong as the sword's own Sword Qi. A great sword absorbs nature's spiritual energy, which gives it immense strength. This is related to the wielder; the stronger you are, the stronger it becomes.
