After the assistants of Zhou Xixian and Ye Bo left, they were waiting for the identification result.

The age identification of fossils is actually not difficult. The relative age has always been determined based on the stratum in which it was found, but since people ’s understanding of atoms has gradually deepened, scientists have found ways to identify absolute ages.

Most of the substances found in nature are composed of several isotopes (ie, various atoms with the same atomic number but different mass numbers). Some isotopes are radioactive, that is, their nuclei spontaneously emit rays and gradually transform into another substance. For example, the radioactive isotope 14c morphs into 14n.

Each radioisotope has its own rate of metamorphosis, which is called the "half-life" —the time it takes for a substance to decay by half its atomic number. Therefore, if we know the half-life of various isotopes, it is not difficult to calculate the age of an object containing this isotope, as long as we measure how much isotope remains.

At present, the two most widely used methods are the 14c method, which is used to identify organic matter; and the 40k-40ar method, which is used to identify volcanic strata and related fossils. Taking the 40k-40ar method as an example, argon is the decay product of the radioisotope potassium. The half-life of this isotope potassium is 1.3 billion years, so it is easy to determine the age of the specimen. At present, this French method has been developed to be extremely precise. It can not only identify specimens that are only about 50,000 years old, but also specimens that are the same age as the earth, with very little error.

After a while, Zhou Xixian ’s assistant called back first.

"Is the identification result out yet?" Zhou Xixian asked a little while lowering his voice.

"The result came out, about 200 million years ago." An excited voice came from the phone.

"Isn't it wrong?" Zhou Xixian's pupils suddenly brightened and his voice shook slightly. Two hundred million years ago. In other words, that is, the late Triassic period, earlier than the Jurassic period where the dinosaurs were.

"It is impossible to make a mistake. We have identified it twice, teacher. The value of this fossil is extraordinary ..."

“It ’s not necessary for you to tell me.” Zhou Xixian was afraid that Ye Bo would hear it. He hung up the phone and pressed down his excitement. He walked to Su Jing and planned to take the first step to take the fossil.

Yeah, Ye Bo's excited voice sounded at this time: "What? Two hundred million years ago?" Ye Bo was calling, apparently his assistant. After identification, the same results were obtained.

"Mr. Su, this fossil must be brought back to Institute of Archaelogy by me." Zhou Xixian knows that the plan secretly won, and takes the lead.

"Nonsense, do you understand what is first come, first come, I should bring back the ancient Biological Research Institute." Ye Bo is also very excited, this spider fossil is earlier than the earliest relatively complete spider fossil that has been found so far. At least 35 million years. There is no doubt that this is a precious fossil with great archaeological and research value.

"So compete fairly. I'll pay 100,000." Zhou Xixian said.

"I ... I'm out of 150,000." Ye Bo's mouth twitched, his heart anxious, because he knew. He used money to scramble, he couldn't grab it at all, not that Institute of Archaelogy had too much money, but that Old Zhou itself was rich.

"Three hundred thousand." Zhou Xixian said calmly and calmly.

"Thirty ... 350,000." Ye Bo was out.

"500,000." Zhou Xixian indifferently said, Ye Bo suddenly speechless, blowing his beard glared, his face flushed, Zhou Xixian smiled, "Hehe. It seems that this fossil belongs to me."

"Old Zhou, I see this fossil. More than this price." Su Jing smiled.

"It can't be said that this fossil is for ordinary people. It's just a stone, only us old things like it, so if you want to sell it at a high price, it's unlikely." Zhou Xixian waved his hand.

"Don't listen to him, you can get this fossil at the auction house, at least one million." Ye Bo couldn't get it himself, but he didn't want to make Zhou Xixian so easy to get. It is estimated that many unique collectors like this unique fossil, and they really want to sell it. It will not be less than one million. If no earlier spider fossils are found in the next few years, the price will increase.

"You are immortal, this fossil is strictly a national property, can you get it at an auction place? You brought me Institute of Archaelogy, I am contributing to the country." Zhou Xixian said angrily, but I was really afraid Su Jing sold it and said, "One million is one million. How about selling Mr. Su to me more quickly?"

Yebo stopped talking. He did n’t really want Su Jing to sell the fossils to the auction house. In contrast, selling to Institute of Archaelogy is still much better than selling to private individuals. He just wanted to hang Zhou Xixian. Forget it.

"Ok Zhou Lao, I will sell you a million, but there is a condition that when you do n’t use the fossil, you occasionally research and study Old Mister Ye." Su Jing said, just released the spiritual force detection, according to the spiritual fluctuation of Zhou Xixian Look, this should be his highest price. If he lifts it up again, he may not buy it. Such a piece of fossil that is useless to oneself is sold for one million even if it changes hands. This business is not in vain. As for speaking for Ye Bo, it is on the face of Xue Zhonghong.

"This is all right. If there are any fossils or something like that, remember to come to me." Zhou Xixian glanced at Ye Bo and reluctantly agreed to it. I was afraid that Su Jing would resent it and immediately transferred a million to Su Jing. .

"Thank you Mr. Su." Ye Bo also smiled.

"It's just a effort." Su Jing smiled.

Li Guanglei and the others, who heard the conversation faintly not far away, could n’t help but wonder, Su Jing is so rich, can afford such a building, the first floor is even reinforced with alloy plates, it turns out that he is so easy to make money, a stone can be Sell ​​one million. When do I pick up a few pieces of fossils myself, to see if I can sell tens of millions.

"Speaking of this, this spider is so well preserved, it's really strange." Zhou Xixian held the fossil, doubtful, and Ye Bo didn't speak, but rarely agreed with nodded.

"Why is it strange?" Su Jing asked.

"The best intact spider fossils discovered before this time were because they were buried by fine volcanic ash, so the fragile outer bone marrow was not destroyed, it was just squashed, but this one was obviously not What is the reason? "Zhou Xixian said.

"This ... you don't know that it is even more impossible for me to know." Su Jing said this, but it was a bit of a joke in his heart. Is it because of the toughness of the spider body of the A Record of a Mortal's Journey to Immortality world? For example, the giant spider, who was hit by a rock, didn't die immediately, and his body was basically intact. If it was an earth spider, it would have become a meatloaf. However, this reason cannot be explained.

"Well, take it home and study it." Zhou Xixian greeted the assistant, picked up the fossil, and left happily. Ye Bo also left with Su Jing. Looking at the backs of the two, Su Jing thought, hoping that they would n’t waste too much time on it. After all, no matter what they researched, there was actually a big deviation from the earth.
