613 The Man With the Mustache Arrives!

Qin Yu held the bronze sword and walked quickly to the door.

Standing at the door, Qin Yu couldn't help but feel a little nervous.

Whether or not he could break through the door depended on the bronze sword in his hand.

"Buzz!!" 

As Qin Yu injected his spiritual power, the bronze sword exploded with a dazzling light. The entire sword seemed to have been endowed with life, and it was trembling non-stop!

Qin Yu shouted loudly, and the bronze sword in his hand immediately swung towards the door!

"Clang!" 

The loud sound was deafening! The terrifying recoil force even forced Qin Yu back a few steps!

Under the tremendous power of the bronze sword, a shocking scar was cut on the door!

"It's finally effective!" Qin Yu's eyes flickered with a strange light, and hope was ignited in the bottom of his heart!

He held the bronze sword and slashed at the door again!

The door rumbled again, and another mark appeared!
