Zhu Fei had discovered that there was a Transmission Array at the end of the hall's passage well before.
However, this Transmission Array was almost identical to the one he and the two women had used before, which also required Top-grade Spirit Stones to be activated.
At this moment, Zhu Fei had already arrived near the Transmission Array.
He took out three Top-grade Spirit Stones from his ring and threw them into the slots beside the Array one after another.
Fortunately, this Transmission Array wasn't damaged, and as soon as Zhu Fei placed the Top-grade Spirit Stones in, spatial fluctuations began emanating from the array.
With a flash of light, Zhu Fei's figure had completely vanished from the spot.
When he reappeared again, Zhu Fei was shocked to find that he had actually arrived in an Undersea City!
The entire Undersea City was seemingly guarded by some kind of large-scale Array, which kept the ocean waters at bay from the city.
