章 242: Chapter 231: Let's Set It Up Like This

"Let's go upstairs and have a look." Having finished exploring the lobby on the first floor, Xia Yue wanted to go upstairs out of curiosity. She had already found some stairs that could automatically move upwards.

Having said that, she walked towards the stairs, with Yan Mo and Ao Ye following her.

Once they stepped on the stairs, they automatically moved upwards.

"These stairs operate with the ocean currents; as long as the ocean has movement, these stairs will always operate," Dragon Lord Ao Ye explained to them.

"How is that possible?" Xia Yue asked curiously. She knew about ocean currents, but she did not understand how they could power the stairs.

"An array was used. From the moment the castle was built, the array began to work. Wherever the castle needs automatic operation, the array converts the kinetic energy of the ocean currents into electricity, ensuring the normal operation of the castle," Dragon Lord Ao Ye elaborated.
