The Right Weapon

On the other end of the call, Shen Nianzu's brows subtly gathered into a frown. "The Nightmare's weakness… does it really exist?"

It's not like he doubted Grandpa Song. The fact that the other person had left behind such a message must mean that he had discovered something. Yet it had cost him his life. If it was something even Sword of Heaven couldn't handle, could it still be considered a 'weakness'? 

In response, Xu Zhao let out a muffled chuckle as though sensing the silver-haired man's apprehension. "Who knows?" he drawled on his words lazily. "Maybe it does exist, maybe not. Why don't you consider this from another angle? Perhaps it's the wrong weapon that has been drawn. To chop off a piece of tough meat, of course you can't choose a dull knife."
