This palm strike directly suppressed Kuzai's Vitality Points to one-fifth. If it weren't for the fact that his recovery rate of Vitality Points was getting faster, this blow would have definitely caused him serious harm.
Song Jian's brow furrowed slightly. If he couldn't kill Kuzai instantly, then no matter how powerful his skills were, he wouldn't be able to kill him completely. They could only fight head-on until the opponent's soul was completely burned out.
The Sword Qi Palm Imprint was already the limit of what Song Jian could control in the Thousand Swords Art by himself. As for the Sword Qi Stone Tower, he couldn't possibly continue to evolve it based on his understanding of the Thousand Swords Art if he had to control it on his own.
With a cold snort, Song Jian somewhat reluctantly let go of his control over the Thousand Swords Art. The subsequent evolution process began to be controlled by the Sword Spirit of the Sky-breaking Sword.
