If they wanted to go to the tower, they needed the flood dragon's help, so Gu Ning called the flood dragon over and told it to take them there.
The flood dragon waited aside and watched Gu Ning and Leng Shaoting walking towards the tower.
Gu Ning and Leng Shaoting were unwilling to give up, so they kept on looking for the catch.
All of a sudden, Gu Ning had an idea. "Maybe we need to use magical energy to open it."
Magical energy was the energy made by magical power. However, Leng Shaoting wasn't able to form magical energy right now.
Gu Ning thought for a while, but didn't think it was a good idea, because the tower would be vulnerable if magical energy could easily open its door.
Once again, Gu Ning used her Jade Eyes to see the inside of the tower, but she only saw darkness.
