Jiang Yu was extremely curious about the sword in his hand. He couldn't understand how it was made. How could it be so powerful? no matter how strong the battle corpse's defense was, it could still be cut in half by this sword. This sword was too terrifying.
What made Jiang Yu even more curious was that the sword didn't seem to be very sharp. It didn't seem like the sword was sharp enough to cut people in half. When the sword hit someone, it would shake violently at a very high frequency. In the end, whatever the sword hit would be cut in half under this strong vibration.
This was a very novel weapon. The sword's body vibrated, but the hilt could not feel it at all. If he had not been paying close attention to it, he would not have discovered the secret of this greatsword.
