He estimated that if previously it took ten collisions to break, now it would take twenty, and with further tempering, it might reach the strength of a top-grade mundane weapon.
The most important thing was that now, when Gu Wen introspected his Fate Diagram, the Heavenly Marrow required for the Fifth level of the Yuqing Sword Skill had been reduced to thirty years of Heavenly Marrow, a total reduction of ten years.

And with all the Heavenly Marrow he could currently obtain in the short term, it should be enough for him to form his Sword Dao Dharma.
