"Mountain Moving and Sea Filling?"
Ye Chen was somewhat puzzled, what relation does mountain moving and sea filling have with delaying the destruction of the sealed barrier?
An aged voice continued, "Do you know why the border between the Seven Divine Countries and the Outer Realm is this Wuwan Sea?"
Ye Chen's eyes flashed slightly, indeed, this is quite strange. The Seven Divine Countries are located in seven different spaces, theoretically, they shouldn't be connected?
The voice continued, "That's because the so-called Wuwan Sea, in truth, flows from the Netherworld Sea Domain. The existence of Wuwan Sea itself is a means of strengthening the connection between the Outer Realm and the Divine Kingdom. If you fill up this Wuwan Sea, invading Outer Heaven Demons will find it much more difficult!"
"Moreover, the mountains used for filling aren't ordinary rocks. Ordinary stones cannot resist the erosion of the Wuwan Sea!"
Ye Chen said, "Then what kind of mountain should be used?"
