Jin Liufu took advantage of the moment when the monster was hindered by the vines, moved like lightning, and quickly pulled out a specially-made hidden weapon from his bosom.
The hidden weapon glittered with a cold light under the dim illumination, like a star shimmering in the night sky.
He swung his hand to launch it, and the hidden weapon cut through the air with a piercing whistle, "whoosh whoosh", like an arrow off the string, rapidly shot towards the monster. In the blink of an eye, the hidden weapon hit the monster, but only a few sparks scattered, "crackling" like striking hard steel, failing to inflict any substantial damage.
"Why is this monster so difficult!" Jin Liufu shouted anxiously, a hint of despair in his voice, which echoed helplessly in the dim space.
