"Yueyue, is this what you painted? What is the drawing? Leng Qingqiu picked up the notebook curiously.

"Oh, a fragment of a mussel shell, I wanted to make it a trinket."

"Fragments of mussel shells? What kind of fragments? Leng Qingqiu asked excitedly, "Can you show it to me?" ”

"Okay." Anyway, the dean's grandfather is not an outsider.

Leng Xiyue entered the bedroom and generously showed the five fragments to Leng Qingqiu.

"Isn't that what I'm going to identify?" Leng Qingqiu took the fragment curiously, and after observing it repeatedly, he asked, "Yueyue, where did you get these treasures?" ”

"Picked up by the river." Leng Xiyue said.

"By the river? Which river? Leng Qingqiu became more and more excited.

As soon as Leng Xiyue heard this, she knew that these mussel shells were very valuable, and she had the impression that the dean's grandfather was very interested in archaeology, and he should be able to see the value of the mussel shell fragments.

"Grandpa Dean, can you tell the age of this mussel?"

"I couldn't do it before, but now that my vision has returned, it's totally okay." Leng Qingqiu looked at the fragments of mussel shells one by one, looked at the light for a long time, and said with great certainty, "More than 77,000 years." ”

What? More than 77,000 years! Leng Xiyue couldn't believe it, did that river mussel live for so long?

If this is the case, then wouldn't the spirit bead in her body also have 77,000 years of spiritual power?

"Grandpa Dean, how do you tell its age, can you teach me?" Leng Xiyue is eager to learn this knowledge.

Leng Qingqiu picked up one of the fragments, "This mussel is a very rare ancient creature, called the colorful pearl mussel, which has been extinct for more than 50 million years, it likes to live in a cave at the bottom of the river or at the bottom of the river, when it was first born, the mussel shell was gray, and there were many circles on the back, and the circle pattern was its age."

Every year, a red pattern appears on its shell, and every ten years, an orange pattern grows on its shell; Every 100 years, a golden vein will appear, a green vein will appear every 1,000 years, and a purple vein will appear every 10,000 years.

On this fragment, there are seven purple lines, seven green lines, and gold, orange, and red lines, which are too many to count, and from these colors, it has lived for at least 77,000 years. ”

Colorful pearl mussels, 77,000 years! Leng Xiyue heard such a shocking statement for the first time, picked up the mussel shell and looked at it carefully for a long time, and said suspiciously, "Grandpa Dean, how did you see that it has seven purple and seven green?" Why can't I see it? ”

Leng Qingqiu smiled, "Because you haven't studied it, ordinary people can only see the age of the colorful pearl mussel from the back of the complete mussel shell, and archaeological experts are skilled." ”

As he spoke, Leng Qingqiu put the mussel shell fragments in the light, "Yueyue, take a look now, are there any new discoveries?" ”

Leng Xiyue looked at it curiously, but she didn't expect that this fragment of mussel shell greeted the light, and a complete image of the mussel shell appeared, just like the complete river mussel she saw underwater, how many colors it had on its body could be very clearly displayed.

It turned out that the dean's grandfather could see the age of the river mussel through the light, and Leng Xiyue felt that she had gained too much today.

Since this mussel has lived for so long, its mussel shell must have an unusual effect, maybe it can prevent and cure diseases, and make people immortal.

Just thinking like this, I only heard Leng Qingqiu say, "According to historical records, the colorful pearl mussel is a mascot in the water, which can eliminate disasters and ward off evil spirits. ”
