"If I also combine it with the Nine Words Mantra Secret Technique..."
Lu Changsheng understood the importance of the Heart Sword Technique in his heart.
He even wanted to merge the Nine Words Mantra Secret Technique with the Heart Sword Technique.
So that every time the Heart Sword was slashed, it could carry the effects of the Nine Words Mantra Secret Technique.
In this way, the power of the Heart Sword would soar tremendously.
Truly becoming a terrifying Spiritual Secret Technique!
With Lu Changsheng's current comprehension, merging the two secret techniques shouldn't be difficult.
In the blink of an eye, a month had passed.
During this month, Lu Changsheng focused most of his energy on merging the Nine Words Mantra Secret Technique with the Heart Sword Technique.
With his nearly four thousand points of comprehension, it took Lu Changsheng a whole month to finally merge the two secret techniques.
The merged secret technique was called the Heart Sword True Words!
