Long Haochen’s hollow strike was extremely inconvenient for the Fiend Commander who was in the midst of his offense. His sword that was in an offensive flow was forcibly retracted in midair. He did so because he realized that if he kept his attack going, Long Haochen’s divine sword would undoubtedly strike him first. Therefore, he could only change plans.
This was the use of the ‘sword’s transparent heart’. The next instant, Long Haochen could be viewed as a part of the Aria of the Goddess of Light, observing the enemy from the point of view of the sword. The reason for his last strike to be so aggressive was not because he predicted the enemy’s next move, but because he completely saw through his sword’s intent. This attack looked as light as a feather, but was something that opponent had to block no matter what, since it was in the way of his only escape route. This was how he gained the upper hand in a mere instant.
