In fact, Zheng Su had not originally planned to use this move; after all, he was a senior figure, much older than Su Chen, and he had his pride. He intended to hold back somewhat.
But Su Chen's sword made him feel danger, an extreme danger, a cold danger that seemed to freeze his heart.
So, he had no choice, and almost instinctively, he unleashed this move.
After using this move, Zheng Su felt much calmer. The "Return to the Holy Flame Sword" gave him a great sense of security. Not just Zheng Su, but Gao Pu and Xu Yu Jun also felt a bit relieved, clearly understanding the power of Zheng Su's move.
However.
At that moment.
"Ssshhh!"
A harsh, soul-grinding sound of Sword Light clashing suddenly erupted.
The sound wasn't loud but carried a sense of tearing through the mind.
The air suddenly turned spectacularly colorful, with lights tearing through and the space roaring.
A wave of scorching air surged madly in all directions.
