A Trap
Yang Fang felt his body age significantly after casting the forbidden Godfiend spell. He had probably lost several years of his lifespan. As for Zhang Yunfeng, he was already very old. The side-effects for using a forbidden Godfiend spell was even greater. One could see Zhang Yunfeng grow older visibly.
"Haha, I cultivate the Indestructible Divine Body. I'm the best when it comes to healing," said Zhang Yunfeng with a smile. "Before I die, I can maintain my peak strength. Even if I don't take action now, I can only live for two to three years. I should do more while I'm still alive. When it comes to killing demon monarchs, I can match 10 to 20 Great Solar Godfiends."
