No words were spoken through the night.
Time quickly came to noon of the next day.
After sleeping until midday, Li Jing got up to prepare lunch and checked his panel.
About eight hours later, the cultivation progress of the Flying Sword Blue Edge improved from 3% to 7%, and the Linglong Tower's cultivation progress increased by 2%.
The spiritual power intensity increase brought by the four-level advancement last night was indeed significant.
He estimated that under the effect of 756 spiritual power intensity, the efficiency of cultivating a Level Nine Treasure would increase by 10% every day. Therefore, it might take another ten or so days for the Flying Sword Blue Edge to reach Treasure Level 10.
This efficiency, he had to say, was quite delightful.
After reaching Treasure Level 10, even if the cultivation efficiency decreased by half, the Flying Sword Blue Edge would become a Spirit Weapon within twenty days.
As for the Linglong Tower, it can be disregarded for now.
