The surface of the water is rippling and tumbling. In the distance, the surface of the water formed a whirlpool that Yu Huaiwen said, slowly rolling towards them.

Qin Weimian looked at the entrance of the water cave that was close at hand, and suddenly had an idea, and this idea also matured in his heart.

He swam slowly over, and then suddenly pushed Yu Huaiwen out as he approached the entrance of the cave.

Seeing the turbulent whirlpool rolling towards him, he took off the long Xiao around his waist, put the long Xiao to his mouth, and then blew the water between the long Xiao to make a sound.

Then the whirlpool rushed straight to the mouth of the water hole beside him, and with a bang, the infinite water splashed at the bottom of the water, and the huge resistance swept him and Yu Huaiwen away.

Yu Huaiwen also gasped at this time, held her breath, and then swam towards the entrance of the cave.

The sudden huge resistance made her backwards, a little powerless to move forward.

Sudden tiredness welled up in her heart, and her hands looked weakly at the person who was swimming towards her.

Qin Weimian took one of her hands first, so that she would not sink again. Then he wrapped his arms around her waist and walked together towards the hole that had broken the barrier.

Even if the water hole broke through the barrier, no water would enter.

After Yu Huaiwen was pulled towards the entrance of the cave by Qin Weimian, she collapsed directly to the ground, breathing in a big breath of fresh air.

Neither of them looked at anyone, and there was a hint of embarrassment in the air, and they didn't know how to speak.

When Yu Huaiwen had breathed enough and rested enough, Qin Weimian stepped out, and the two of them tacitly explored forward, and they had a tacit understanding of whether they had mentioned what had just happened.

This cave is really different.

The walls of the cave were inlaid with sapphire crystals, and the blue light shimmered, blinding the human eye.

And the color of the sapphire gradually changes from blue to purple, which is very beautiful.

In her head, a sudden sound came from the system, and knowledge related to crystals entered her mind.

Crystal, also known as jade in water. In China, the oldest name is called water jade, which means jade like water, and it is also said to be "melted by ice for thousands of years", and it is generally said that "it is as clear as water, and it is as hard as jade".

Crystal is also known as the water spirit, that is: "the water spirit".

And the disciples of Buddhism are convinced that the crystal will shine with magical spiritual light, which can benefit all sentient beings. So the crystal was revered as a bodhisattva stone.

It is not surprising that there are many things in the world. And crystal has many other names, such as, water jade, water jade, white jade, jade ying, water spirit, quartz, Li Nan, crystal jade, Bodhisattva stone, horse tooth stone, spectacle stone, light stone, millennium ice, alpine jelly, fish brain jelly and so on.
