It would be best if it was the embryo type!
In the future, he could continue to improve.
Back then, his first literary weapon was the embryo, and he had not gone deep into forging. However, Su Yu’s strength had advanced too quickly, and that embryo could no longer satisfy his needs.
The current Su Yu was much more powerful than he was back then.
Moreover... Su Yu was thinking about a problem.
Body 72 casting!
Forging might allow him to advance faster. Once he advanced and completed the 72 casting, Su Yu might step into Ling Yun. After all, he had already completed the transformation of his 144 apertures.
If he made a breakthrough during the forging process, it might help him to forge and make the weapon stronger.
It was better to forge the weapon himself.
Especially for the will of the ten thousand clans, he needed to do it himself.
