"What happened?" Lu Wangyi and Ju Jushen asked simultaneously as soon as Zhang Fei reappeared on the third floor.
"This." Zhang Fei showed them the key.
"Key?" Lu Wangyi and Ju Jushen looked at the gate. "Don't tell us that's the key to opening the gate."
"This key is indeed for opening the gate."
Zhang Fei walked to the gate, but Dugu Yuanshen grabbed his shoulder. "Are you serious about opening this gate, young man?"
"I don't know, Senior." Zhang Fei moved Dugu Yuanshen from his shoulder. "I have to look for two items in the Ancient Realm, so I have to go there, but I'm not sure about opening this gate. Those shadowy creatures had already invaded the Tower of Eternity in the Zhanlu Domain, and they would invade this tower as soon as I opened the gate."
Dugu Liangsen wore a confused look and asked. "What do you mean by those shadowy creatures, little brother? Where is Zhanlu Domain located? Why haven't I heard of it before?"
