Han Fei remembered that Hai Tinglei had sent Bai Wuzhu and Yu Qing to guard the Demon Subduing Tower.
Therefore, Han Fei felt that he might appear in front of these two people after entering the cave. Then he could threaten them.
He could tell the two of them that as long as they didn't announce that he had been there, he could take them as his followers and take them back from there.
Han Fei believed that no one could resist such temptation. After all, 30 years was not short. No one would want to stay in such a dangerous place to watch the door. They would definitely know how to choose.
However, the moment Han Fei stepped into the cave of the Demon Subduing Tower, he seemed to have fallen into a vortex and appeared directly in a jungle under the sea.
Han Fei was stunned and asked in surprise, "Undersea Jungle? Where is the Demon Subduing Tower?"
