When Yan Zhen and the other four arrived at the Thunders City, they didn't do anything. They just used their power to contain the few scouts staying in the city so that the latter couldn't move about.
Yan Zhen's psychic power was target-fixed on Lu Li. The former's rigid face seemed to be covered with surprise. Lu Li had reached the Semi-God Realm. But according to Jun Hongye, Lu Li had just reached the Earth Immortal Realm a few years ago.
A young man had progressed from the Earth Immortal Realm to the Semi-God Realm in a few years. The nine universes would be taken aback by such a piece of news. Even Yan Tiangang, the alleged most talented warrior in the Yan Family, used 10 years to progress from the Earth Immortal Realm to the Semi-God Realm.
