Lu Li didn't let the immortal's body take him far away. He could run at any time. Yan Zhen couldn't hurt him.
Lu Li told He Yue to mobilize subsidiary bodies to monitor Yan Zhen. What Yan Zhen said troubled Lu Li. Yan Zhen must have been completely angered. He wanted to go to Heaven Reverse Universe to vent his anger and, at the same time, force Lu Li to surrender and compromise.
Lu Li tried hard to find a solution. Intimidating words wouldn't scare Yan Zhen. There was only one way for Lu Li to go now, which was to go to the Divine Imperial Universe and force Yan Zhen back so that neither would invade the other's home.
