521 Treasure in the Sea

The three sails rose at the same time. The mysterious and gorgeous crystal sailboat slowly rose from the bottom of the lake and floated in the water in a magical way, looking magnificent.

"My girl, take us toward the ocean." Han Sen was incredibly excited. This crystal sailboat was much better than a submarine. It was an interstellar warship in the water.

"Master, do you want to go above the surface?" asked Mermaid Princess.

"No, let's stay on the bottom." Naturally, Han Sen wouldn't let the crystal sailboat go up to look for trouble.

"Yes, master," replied Mermaid Princess and turned the rudder in her hand. The giant crystal sailboat suddenly sailed toward the ocean, following a channel connecting the lake and the ocean.

The scenery at the bottom of the sea was indeed incredible. Han Sen saw a region of shellfish, which piled up like small mountains for hundreds of miles.
