When Yang Xu learned from Yiying.
Academician Zhou from the Institute of Geology and Palaeontology of the Chinese Academy of Sciences called.
He vaguely felt that things might not be easy.
The two talked briefly about the details of the mammoth ivory through the video call.
Academician Zhou Zhiyan of the Chinese Academy of Sciences is over fifty years old.
Although he is not very old, he has all the black hair on his head.
"Hello, Comrade Yang Xu, after preliminary estimates from our research institute, your mammoth tusks have an amazingly high density!"
Academician Zhou looked very excited.
Can make an expert academician in paleontology scientific research.
The reason for such excitement.
There can only be new scientific discoveries!
Yang Xu and Yiying looked at each other.
The two are unclear.
But about the density of ivory.
Yang Xu still knows a little bit.
Because the dead mammoths are frozen in frozen ground all year round.
Thousands of years have changed.
It will loosen the interior of the ivory, reduce its density, and reduce its weight.
Therefore, the higher the density, the heavier the weight.
Subsequently.
Academician Zhou of the Institute of Geology and Biology.
A brief description of the scientific research results related to the density of mammoth ivory.
The result of scientific research that may be derived indirectly is that the mammoth's death time 553 is not 5500 years old!
It is possible to change the timeline of the extinction of this species!
When did the behemoths of the Ice Age retreat from the stage of history?
The result of this previous demonstration.
It will be redefined because of Yang Xu's discovery!
"Brother Xu, are you accidentally changing your historical perception?"
Yiying whispered: "This way, I can have one more cold knowledge?"
Academician Zhou on the video call continued:
"The median density of ordinary mammoth ivory is approximately 1.75 grams per cubic centimeter."
"According to the data provided by Comrade Yang Xu, our preliminary estimate of the density is 2.5 grams per cubic centimeter."
Finally, Academician Zhou added: "Because of the incomplete data and the absence of a specimen of mammoth ivory, this conjecture cannot be established yet."
"Once the results of bioarchaeology are proven, then the time for the extinction of the mammoth will be delayed by your discovery, at least 500-1000 years!"
Yiying was stunned.
Even the mouth opened into an O shape.
If we say, Yang Xu discovered the new species 'Pacific panda dolphin'.
Will appear on the "Encyclopedia of Marine Biology" because of his obviousness.
So!
If the results of scientific research on mammoth ivory are established.
It's not too much to say that it is written in the annals of history~
At this moment, Yiying has only one thought in her mind, Xu brother has done a big deal~
…
Yang Xu isn't a chirping person either.
I promised to get some scraps for the Chinese Academy of Sciences to do research.
He didn't delay time either.
After briefly understanding the situation with Academician Zhou Zhiyan.
Yang Xu was prepared before leaving the port.
Hand over the leftovers of mammoth ivory to the Chinese Academy of Sciences.
After all, the first time the other party contacted him was an academician-level scientific research expert.
It can be seen that the sincerity is full.
It also belongs to the "Institute of Marine Biology" of the Chinese Academy of Sciences.
It happened to have cooperation and exchange activities with the Alaska "Marine Life Center".
Yang Xu only needs leftovers from mammoth ivory.
Give it to the people at the Institute of Marine Biology.
They will then transfer it to the 'Yanjing Institute of Geology and Paleontology'.
Come and go.
There is no need for Yang Xu to bother too much.
also.
Mammoth ivory was discovered by Yang Xu in the polar tundra of Alaska.
He has the right to use the 'Wooden House Permit Point'.
There is no need to consider the ownership of mammoth ivory.
The privilege of the 'Wooden House Permit Point' is free hunting, as long as it does not sell protected wild animals.
Mammoth ivory does not fall into these categories.
Naturally, he can handle it by himself.
The Chinese Academy of Sciences only needs to provide a certificate of scientific research use of mammoth ivory into the customs.
…
The whole process only took half a day.
And before the research results came out.
The 'Yanjing Institute of Geology and Paleontology, Chinese Academy of Sciences' did not issue an official draft.
After all, scientific research does not recognize theories but only the results.
Only the results came out.
Only then can we announce the conclusion that the extinction time of the mammoth has been 'postponed'.
What Yang Xu gave to the Chinese Academy of Sciences for scientific research was just leftovers that he originally planned to cut off.
The complete body of ivory will remain in the collection on the'Yunfan'.
Yiying joked: "If the theory of the Chinese Academy of Sciences is confirmed, you will be famous again, Brother Xu~"
"It doesn't matter what is famous or not, it just wants to make a contribution to paleontology research." Yang Xu said disapprovingly.
Yi Ying pondered.
Brother Xu's words, the more I hear it, the more I pretend to be X…
"Should we be able to announce the next sailing route tomorrow?" Yiying asked.
Yang Xu replied: "Before this, we still need to get equipment for Yunfan."
"What equipment?" Yiying asked curiously.
Yang Xu said, "Make a big aquarium, if you have rare and beautiful things in the future, you can keep it in it."
Yiying nodded repeatedly and said, "I agree with this!"
After returning to the port from the glacial tundra in the far north of Alaska.
Yang Xu and Yiying spent a whole day.
Will deal with trivial matters before sailing.
In addition, Alaska's "Marine Life Center" was when it bought Yang Xu's golden king crab.
The promised iconic sculpture is almost complete.
The other party wants to invite Yang Xu and Yiying to attend the completed event.
It was only politely declined by Yang Xu.
The next day, when the live broadcast room was opened.
Yang Xu instructed Yiying to change the title of the live broadcast room to [The new sailing journey begins~]
A live broadcast room with a focus of over 5 million.
A lot of curious audiences flooded in instantly after opening.
[Do you want to announce the next sailing route? You can go to the new sea to increase your knowledge! ]
[Where is Xu brother going back? Continue in the freezing seas of the extreme north? Or go south to the tropical island? ]
[You can dive in tropical waters! There are also sunny beaches, isn't it fragrant~][I can embark on a new journey with Xu brother Yiying again, I'm so excited! ]
Yiying smiled and responded to the audience:
"Here I am almost frozen as a grandson, and I am wrapped up like a big dumb bear every day."
Yang Xu also has no ink marks, and has no intention of selling Guanzi at all.
He cleared his throat and said:
"Next, our Yunfan will go to…
