It took Vale three more days before he decided to try the Soul Bonding Method with the Divine Sword or what he would like to call the Lightning Sword.

After reading all the books he got, he concluded that his bond with Lotus, Yvaine, and his system was already an experience in itself.

It means that perhaps, he no longer needs the hands-on experience that Professor Evans wanted to happen between them before he tries it on his mystical item.

After his class, he immediately went to the Training Hall and rented a room. He brought several things with him, including the wrapped Lightning Sword. 

He chose this place since it already has a Formation Circle that isolates and protects the room from any outside interference.

He took out his Sword and unwrapped it.

He placed it in the middle of the room and looked at its gorgeous design. Its silver blade and black hilt have intricate marks and a faint glow.
