Lightning God Possession

"Ye Mo, no one in our generation has ever managed to make me use the Violet Lightning Spear," Cao Zheng said. "You're the first. Every time I use my Violet Lightning Spear, it requires blood to feast on. Otherwise, it gets unhappy." With his left hand, he wielded the spear while his right hand held the sword. Next, he joined the two from the hilts of the weapons.

Cao Zheng was wielding a weapon that was a sword at one end and a spear at the other end. Two Spirit Weapons had been combined into one.
