Dr. Doom made a knockout gesture and was pulled into a strange place, as if he had a whole new body.

He opened his eyes, he was in a box, and suddenly the box was opened, and Emma's holographic projection appeared in front of him, and there were two silver-white robots on the side, as if to make it easier for everyone to identify themselves, there was a holographic projection font floating above the robot's head.

The two robots have the red fonts of [Di Ying] and [Kudo Yanzhi] suspended above their heads respectively, so there should also be the red font of [Victor 61 von 61 Dum] on the top of his head.

"Doctors, you're trying to move your body now, and there's a five-senses test on the side." Emma said, pointing to a workbench to the side.

The so-called five-sense test is actually to ensure that the stand-in robot can truly transmit these feelings to the user and avoid serious errors.

Dr. Doom was very curious and picked up something like soap.

[Please put it in your mouth and taste the flavor of the item.] Dr. Doom put "soap" in his mouth, and the smell of strawberries permeated his mouth.

"Strawberry flavor."

[Answered correctly.] ］

Di Ying and Kudo Yanzhi also tested it in the same way, and after half an hour of testing, the physical activity, bionic function, and five senses transmission of their stand-in robots were completely normal.

At this time, Emma took them to meet Liao Qingsong, the base manager of the Mars base, and after introducing Liao Qingsong and the three doctors to each other, Emma's holographic projection disappeared in front of everyone.

"Liao, can you take us to see the Martian paleontological fossils?" Dr. Doom asked impatiently.

Di Ying and Kudo Yanzhi also looked at Liao Qingsong eagerly, Liao Qingsong nodded and said, "Okay, the three doctors come with me!" ”

Led by Liao Qingsong, after bypassing the five compartments, everyone entered an isolated storage chamber, which stored a total of 50 samples of Martian paleontological fossils collected from Centipede Canyon.

Looking at the samples in the storage boxes, Dr. Doom knew at a glance that there was a very high probability that these things were fossils, and he asked eagerly, "Can I open it?"

"Wait a minute, I'll go to the next cabin before you can open it." Liao Qingsong himself is now in the storage chamber himself, and he can't have direct contact with these fossil samples.

When he got out of the storage compartment, he closed the hatch and said over the intercom, "Three doctors, you can open the sample storage box, the password is four zeros." ”

“OK。” Dr. Doom hurriedly selected a centipede-like fossil and dripped ...... [0000] After entering the password, the storage box automatically pops open, and the centipede-like fossils inside appear in front of his eyes.

This piece of sedimentary rock is grayish-white as a whole, and the centipede-like fossil is entrenched in the middle of the sedimentary rock, the centipede-like fossil is black-red, the length is about 1.2 meters, the width is between 0.13~0.15 meters, there is a pair of knotted legs, how many pairs are to be studied, and the other is a knotted crust-like body, which looks really like an enlarged version of a centipede.

"Liao, do you have any research equipment?" Dr. Doom asked, turning his head.

Liao Qingsong replied through the walkie-talkie: "The cabin on the left is a small laboratory, and the password is also four zeros. ”

"Thank you." Dr. Doom hurriedly put down the fossil and opened the small laboratory on the left, just as he was looking for tools to move the fossil to the laboratory, when suddenly he remembered that this stand-in robot could lift a maximum weight of 800 kilograms, Dr. Doom tried to lift the fossil storage box, and sure enough, he easily lifted the box.

After entering the laboratory, he couldn't wait to study it, and Di Ying and Kudo Yanzhi also took action and began to study these fossil samples.

Time flies, and before I know it, I have come to March 3, 1st year of the galaxy.

On the Martian space station, Dr. Doom, who had just eaten, came to the lounge and saw Dr. Diying, who had some fat eyes, and Kudo Yanzhi, who was burying his head in the information.

Kudo raised his glasses and asked, "How are you doing your research?"

"I have preliminarily divided these paleontological fossils, and so far a total of 6 classes and 46 species of paleontology have been discovered, but there are no reptiles, mammals, and birds, which are three common species of blue stars." Di Ying said with his cheeks cupped.

"Did you notice a phenomenon?" Dr. Doom said suddenly.

"What phenomenon?" Di Ying asked curiously.

"Dexon has been classifying fossils these days, and may not have studied this aspect yet." Kudo seemed to know what Dr. Doom was trying to say.

"The fossils of 1.2054~120.55 million years are too dense." As he spoke, Doom opened the holographic bracelet, and some pictures of him going on a field trip to Centipede Canyon through a stand-in robot appeared in front of the trio.

Kudo Yanzhi raised his glasses and said: "I also found this problem, after I counted fossil samples and field investigation and analysis, I found that in the period of 1.2054~1.2055, the number of fossils appeared is huge, and the total number of fossils we have found is 19,764, of which 1.2054~1.2055 accounts for 31% of the geological age, and the fossil distribution is relatively uniform in the geological age before this, 1.2054~1.2055 showed the peak of fossil formation, and then there was a cliff-like situation, and after 1.193, the fossils did not appear again. ”

Di Ying frowned when he heard this: "There is only one explanation for this situation, that is, during the period of 1.2054~1.2055, there was a mass extinction on Mars. ”

Dr. Doom nodded: "I think the same way, many of the fossils before 1.2054~1.2055 are incomplete, but during 1.2054~1.2055, most of the fossils are complete, which shows that their death time is very dense and close, and it is a large-scale extinction." ”

"However, we can't say for sure at this time, and this finding only proves that there was a single extinction in the southern part of the Utopia Plains." Kudo continued.

"It's true, we need to do it in other parts of Mars, and if this happens in other regions, the results speak for themselves." Di Ying echoed.

Dr. Doom continued to look at the laboratory data, this sudden extinction of organisms has also happened in the history of Blue Star, such as the most famous dinosaur mass extinction event 65 million years ago, the more he studies paleontology, the more Dr. Doom is in awe of nature, and it can be said that human beings can develop peacefully and steadily for so long, it can be said that it is luck against the sky.

How difficult it is for an intelligent race to develop to the stage of interstellar civilization, the universe is like a big filter, killing 99% of the planets suitable for life in the microbial stage, and the remaining 1% can evolve into multicellular biological planets; 99% of the planet of multicellular organisms will stop here, and the remaining 1% may give birth to intelligent life; And 99% of the planets with intelligent life cannot become interstellar civilizations.

The universe is like a big filter, filtering life planets layer by layer, and it is very rare to have two quasi-interstellar civilizations (Blue Star Civilization and Triangular Civilization) within 100 light years.

There are many planets like Venus that are killed in the microbial stage, and there are countless planets like Mars that are destroyed in the multicellular biological stage.

Dr. Doom opened the shade and looked at the red planet beneath his feet, and for a moment mixed feelings.
