This time, Su Tang saw its appearance clearly. It seems that it is the same species as the holosaurus in the picture, but it's only a lot bigger in front of us! Strongly restraining his impulse to scream, Sutang was very excited and patted Cain's arm“ Ah Yin! This is the sea dragon! This is Wen Biquan! " Cain nodded calmly, grabbed the bright silver white disc in the water and opened his mouth. "This should be the scale that the sea dragon has shed." Sue sugar can't help but stare big eyes, "so much?" When she was in the air, she had a good look! The lake is obviously covered with this kind of bright silver disc, so it can make the lake water reflect a kind of beautiful silver. If this is really the scale of the sea dragon fish, the number of scales is so huge that they can't imagine“ Well Cain nodded with a faint smile. Mermaid people want to improve the dark cold physique, need to take the scales of the sea dragon fish ground into powder and mixed with warm water. Originally, Su Tang was still worried. According to the system, there should be only one sea dragon left. But there are so many people in the mermaid family. It's not easy to improve their physique by one or two pieces. Fish without scales is just like a tree without bark. It will slowly decline. But now it seems that there is no need to worry about it. The sea dragon fish has no idea how long it has lived here, and the scales shed are enough for all the people of the mermaid clan. The only thing they need to worry about now is whether they can find the real key to Muxian mansion as soon as possible. Because here, Su Tang's space is limited and it can't be opened at all. The only way to get these things is to become the successor of Muxian Shenfu. However, some loopholes can be drilled. Sandor only mentioned not to steal and destroy the articles here, but he didn't say not to use them! So, Sutang let Cain condense out a bath bucket, which was full of warm and blue spring water, and then rushed to collect red blood Scrophularia. The whole process went surprisingly well. When Su Tang sat in the spring, he looked at the brown black red blood Scrophularia, which was the same as the white radish in his hand.
