Visible to the naked eye, the blade of the wooden sword turned black.
The black was so dense and cold that several spectators shuddered in horror.
"What's going on with that sword?" Someone asked.
However, no one had an answer so they could only watch as Yu Nianzhen raised the sword.
"Infinite cyclone." Yu Nianzhen muttered.
At the same time, the sword shone with an eerie glow and thousands of silver sword lights flew towards Gong Han.
"Lightning lance." Gong Han shouted and the sound of thunder filled the atmosphere.
A moment later, Gong Han's sabre emitted a silver light and a bolt of silver lightning flew towards Yu Nianzhen.
"Kneel for me and I will let you live." Gong Han shouted and laughed loudly.
In his mind, the fight was already over.
Compared to the blue lightning, the silver lightning was weaker.
However, they were both exhausted.
