Wang Han and Lucky Star stayed on the shore. For safety reasons, Lin Xiajin left a flying vehicle for them and released a gale to help Wang Han. Not only that, Lin Xiajin also left a lot of food for them.

Wang Han has no experience in taking care of children, but Xingyunxing is a relatively well-behaved baby. When Wang Han looks at Xingyunxing, he always thinks of Zhu Jingjing and the children he has not met yet, so he always has a fatherly love for Xingyunxing.

Lin Xiajin and Xiao Nuo had a full meal. After all, they couldn't eat in the sea. In fact, this was why Lin Xiajin was a little curious. How did these people in the water city survive? After packing up, Lin Xiajin gave the water dragon ball to Xiao Nuo. She had no problem holding her breath for several hours under the sea. Her cell density was different from that of ordinary people. She only needed to bring a cold water bead.

Xiao Nuo did not refuse. His breath-holding ability only allowed him to stay in the water for an hour at most. After the two of them were ready, they put on their slippers and went straight into the sea.

This cold water bead does have a certain water-repellent effect. The air pressure of the surrounding water flow becomes very weak, and there is also a certain amount of oxygen.

"The effect of this Cold Water Bead is almost the same as that of the Water Dragon Bead! In fact, the effect of the Cold Water Bead is better!" Lin Xia Jin said. The Cold Water Bead has the effect of repelling water. She can speak, but her voice cannot be transmitted, so Xiao Nuo can't hear clearly what she says.

Lin Xiajin directly took out another cold water bead from the space and placed it in Xiao Nuo's clothes. Now Xiao Nuo could hear what Lin Xiajin said.

It seems that this cold water bead is an upgraded version of the water dragon bead! It is worthy of being a planet in the galaxy. Although such treasures can be found on the seabed, these water dragon beads and cold water beads are treasures for them, but for people living on the cold water planet, these are the most common ones. Almost everyone has them. Otherwise, how can they survive underwater? They know the location of the star beast this time, so they will not take risks anywhere else. The underground city is so big, so they will swim in the opposite direction, at least to avoid the dragon.

Originally, Lin Xiajin and Xiao Nuo could not swim so deep, after all, the pressure from the sea water was too great. However, they both had Cold Water Beads on their bodies, which allowed them to avoid the surrounding water and the pressure of the surrounding water. Without the Cold Water Beads, they would not have been able to dive so deep.

Last time, Lin Xiajin was able to dive down there only because she was wearing the Water Dragon Ball!

The further down he went, the more sparkling cold water beads Lin Xiajin discovered. Lin Xiajin quickly put them into the space. This thing was really good, but soon Lin Xiajin saw a super large cold water bead.

This should be a broken city wall. Lin Xiajin and Xiao Nuo swam over. The water around them was separated automatically, and the two of them fell straight down from above. Fortunately, Lin Xiajin could fly, and he quickly grabbed Xiao Nuo and stabilized their bodies.

The clothes on both of them were wet. Lin Xiajin looked up and saw a huge, sparkling cold water bead above. Lin Xiajin instantly felt that the small cold water bead she had just picked up was not worth much! Are these cold water beads so worthless on Hanshui Star? They were everywhere. Lin Xiajin cherished them at first and collected them one by one. However, with all kinds of cold water beads floating everywhere, Lin Xiajin no longer had any intention of collecting them.

They walked towards the underground water city, and there were cold water beads bigger than basketballs everywhere. In particular, the buildings here seemed to be built with cold water beads.
