"...Besides the astonishing speed at which one's swordsmanship improves, after cultivating a Sword Heart, the most significant benefit is the increase in the power of one's swordsmanship."
"...After I acquired a Sword Heart and began cultivating swordsmanship, I once sparred with a fellow disciple. The two of us used the same sword technique against a mountain. When he struck, he cleaved off a corner of the mountain. Then I struck, and with a single sword, split the mountain open. The sword's might did not disperse, and sword intent surged everywhere. Moments later, the mountain I had split apart turned to dust."
"...A Sword Heart is a special power that a sword cultivator stores within his heart. It complements cultivation, spiritual power, and magical power, making its might even greater."
Lin Bai pored over Yun Fusheng's cultivation insights day and night, reading them over and over three or four times. Each time, he gained a great deal.
Judging by Lin Bai's assessment, when Yun Fusheng wrote these cultivation insights, he had already reached his twilight years and was not far from passing away. At that time, as the Grand Elder of the Eternal Devil Sect, he had wanted to leave something behind for future generations, so he spent some time recording everything he had gained from cultivating throughout his life.
The cultivation insights Lin Bai had obtained mainly described Yun Fusheng's cultivation from the Quasi-Dao Realm to the Dao Immortal level. They also included his understanding of the Sword Heart. These two parts were especially important and were where Lin Bai had gained the most.
After reading through them once more, Lin Bai was still left wanting more and continued reading.
But just then, Qin Yuyan's voice came from outside the door. "Junior Brother Qing Luo, are you still in seclusion?"
