One or two soft lights hit the ground without any changes, but when hundreds of soft lights hit a position at the same time, it is like sunlight focused by a convex lens, and a coin suddenly "burns" out on the ground.

Holes of size.

Ye Geer suddenly heard a "gudong gudong" sound. In a few seconds, the dark sea water emerged from the hole. Then, the entire space began to tremble, and the ground began to appear to the side.

Signs of tilt.

Yegle suddenly felt a suffocation. He wanted to ask what Wilson was doing, but he couldn't speak directly. Before he could write on the tablet, Wilson began to run wildly and run towards the high wall not far away.

Yegel had no choice but to follow.

Before running out a few steps, Yegel discovered something very strange - although the ground was tilting towards the side of the pool, the high wall gradually began to flatten, and the angle between the horizontal plane became increasingly

The smaller.

Assuming that the high wall and the ground are directly fixed at a 90-degree angle, as the ground leans towards the pool, the wall should move to Yegel's head and turn into a new ceiling, but now it looks like a cushion.

The cardboard folded into ninety degrees is slowly spreading out.

Finally, when the angle between the high wall and the ground reached almost 180 degrees, Wilson and Yegel "climbed" up the high wall one after another. Yegel looked back and saw that it emerged from the hole.

The sea water that came has merged with the sea water that has been flooded by the tilt of the ground and is flowing towards this aspect.

As for the dilapidated "Zokok Gai", it had already sunk into the bottom of the pool and disappeared.

Wilson's steps did not stop, and Yegel could only follow him and continue running forward.

...

...

Inside the Tower of Heaven...or in the "City No. 2" of the undersea city.

Ke Lan and Sanshisan have searched three medium-sized block ruins. During this period, they were attacked by a total of fifteen undersea creatures. These creatures that attacked the two, without exception, have very similar genetic sequences to Yinglong.

.

From another perspective, these creatures can be regarded as distant relatives of the prehistoric species, and they are not even considered to be the type that is far away.

Humans and chimpanzees are close relatives in speciesology, with gene similarity of nearly 99%, while dolphins that are both mammals are also as high as 80%... According to Zeluo's analysis, these underwater creatures, and

The genetic similarity of the monster "Seangel" evolved from Yinglong's egg ranges from 95% to 97%. According to the classification method of "Genomes of the Sect Family" in human civilization biology

If we count, these little things that were strangled to death by Zeluo's spatial power could at least be summarized into the same "family" as Yinglong's prehistoric species.

Of course, the premise is that a classification can be specially developed for the prehistoric species in this system... But the problem is that the classification method of biology generally categorizes biological species based on external factors such as appearance and habits. This concept is proposed.

At that time, genetics was not as developed as it is today...

But the most important point is that generally speaking, the higher the gene similarity between two organisms, the higher the approximation in appearance, body structure, and living habits. These two types of attributes show a positive correlation.

It is related, so even after the gradual development of genetics, it did not bring any too much changes to biological classification.

The problem is the prehistoric species - the institute has a research report. Although the author is only a few junior researchers who have just become regular, and the highest title of organizer and instructor is not an associate professor, due to the particularity of the topic selection, the confidentiality of this report

The level is not low, and Ke Lan accidentally caught a glimpse when searching for information after becoming an official member of the Immortal Crew Club.

There is not much content in the report. I don’t know if it is because the research is not in-depth enough or because it is interfered with by external factors. The content of the report also seems a bit vague. In short, it can be attributed to one sentence: existing, known, and can be done.

To the prehistoric species with observable biological tissues, the gene sequences are highly similar.

Ke Lan knew very well what it means to say the four words "highly similar" in the mouth of a researcher.

The kinship between the prehistoric species and the prehistoric species may be closer than that between humans and chimpanzees.

But this report was not made public in the end, and it was not even published on the public website within the institute. This is nothing. For any normal person with a little basic biological knowledge, I saw this report

The first reaction was that I felt it was nonsense... After all, the differences between the prehistoric species were too great. To say that they were close relatives on the genetic level, it would not be convincing.

What's more, this report does not record in detail the research team's samples from prehistoric species, what the status of the samples are, and what methods are used to compare them under what conditions... There is no data, just

There is only one conclusion, just like when the student did not write any problem-solving process during the math exam, he just filled in one answer at the end.

Even if the answer is correct, it will make people feel unconvincing, let alone...

The answer given by this research institute team is like writing three after a question where one plus one equals several.

But Ke Lan, who has read this report, couldn't help but think of a story that once appeared in ancient Chinese myths and legends...

"The dragon gave birth to nine sons, each of which is different."

Perhaps, these prehistoric species are really the same species... maybe.

In addition to this report, Ke Lan also found a brand new term in the internal documents of the institute, called "alpha gene", which is a gene that only exists in the prehistoric species and indigenous organisms of Alpha planet. It is on Earth

The "alpha gene" cannot be found in the gene sequence of organisms.

The same carbon-based organisms, the indigenous organisms of Alpha Star are actually quite similar to those of Earth organisms, but this "alpha gene" is their unique thing.

Many people have tried to "hybridize" the indigenous creatures of Alpha and Earth. Most of them failed, and there are only a few successful examples, but these successful examples have one thing in common, that is, the new birth "

There is no "alpha gene" in the gene sequence of hybrid species.

As long as the "alpha gene" exists in the gene sequence, the fertilized egg cannot even form an embryo.

The only regret is that the institute has not been able to obtain Alpha gene samples, so it is impossible to determine whether the "alpha gene" exists in Alpha human body. In addition, the experiment of "symbionts" is completely under the control of the Immortal Crew Association.

The institute did not intervene, so the institute did not make any breakthrough progress in the research on "alpha gene".

Ke Lan didn't even know that this "alpha gene" does not exist in his body.

There is another short paper about the "alpha gene". The general idea of ​​the article is that the "alpha gene" comes from the prehistoric species, and the "alpha gene" accounts for an extremely high proportion of the gene sequence of the prehistoric species. As for why the alpha star

The indigenous organisms on them will more or less carry some "alpha genes" because the ecology of this planet has been permanently "polluted" by the prehistoric species.

According to the view of this article, the "alpha gene" named after the planet is actually not a local thing born and raised on the Alpha planet, but an "outsider".

Ke Lan also remembered one thing. In the past tens of thousands of years, the indigenous organisms on Alpha have not produced any obvious signs of evolution or mutation, as if their genes have been "locked". Because of this reason,

There was once a saying that "Alpha Star is actually a large biological test site"...

Thinking about it now, this seemingly absurd statement also seems to have some truth...

What about Alpha civilizations? Assuming this statement is correct, what role do they play in it?

Is it the creator of the test site? Or the manager or observer? Or...the experimental subject?

...

Ke Lan was walking through the ruins while thinking about these things, and even Thirty-san stopped and did not notice it immediately.

"Ke Lan, I sensed the large-scale Nino alloy again." Thirty-san said.

"Massive? Could it be the parts scattered by those modified warships?" Ke Lan asked.

"No, it's much bigger than that...unless, unless the entire warship sinks here." Thirty-san shook his head, his facial muscles tensed tightly, and there was a hint of excitement and tension in his eyes.

look.

"Is it because there is a 'Zhenhai-class' cruiser's main body sinking here?" Ke Lan was stunned for a moment. He looked around and continued, "With the scale of this ruin, a cruiser cannot be buried at all, right?

unless……"

Unless you move the ruins away first, dig a pit under the ruins, bury the wreckage of the cruiser, then fill the pits, and finally move the removed ruins back to their original place...

This kind of thing is nonsense even if you think about it.

"Where?" Ke Lan simply stopped thinking about these possibilities and asked directly.

It is better to see it at first sight than to hear it. No matter how messy your mind is, it is better to dig it out and take a look at the real thing.

"It's right at the twelve o'clock where I stand, thirty-five meters."

The place Thirty-three mentioned is a larger ruin. Although it is larger, it is at best an overwhelming twenty-story building. It is absolutely impossible to bury a cruiser.

Ke Lan stepped over the rubble and debris on the ground and stepped into the ruins.

"This building looks very different from other ruins." Thirty-san bent over and picked up a piece of debris, "Look, there seem to be many patterns on it, and the words of Alpha civilization.

The fragments should have peeled off from the wall... Well, they can just meet this gap on the broken wall... There are patterns and texts on the wall that are about to be smoothed."

This building is indeed unique - the architectural style of the Undersea City, or the architectural style of the Alpha civilization, is mainly based on a simple style, especially those residential areas and functional buildings used to live in, and the style is extremely clean.

It is neat and rarely happens when writing and painting on the wall - this is why relics with Alpha civilized texts can be sold at high prices.

Things are precious because they are rare. If relics with texts can be seen everywhere in various relics, the institute and various consortiums will not offer such a high purchase price.

But there is one kind of architectural exception.

"This ruin used to be an altar or temple or other building." Ke Lan said.

"I think so too." Sanshisan nodded in agreement, "Only in religious buildings can a large number of documentary relics be found... This type of relics has the highest benefits, but it is also very dangerous, everywhere

It is a mechanism, and the hunters entering it are often dead and dead... In my impression, those large temples are at least the ruins of the B-level starting point."

"That's right. Moreover, the texts written on these walls are prayers to praise the 'great gods' they believe in." Ke Lan nodded, "This is an extremely standard religious building."

"By the way, it's all collapsed like this, there should be no danger, right?" Thirty-san whispered, "And, the scale of this 'tea' is not very large..."

Those large temples that start "B-level" are usually single temples that can be regarded as super-large buildings or buildings of ruins, and the "small temple" in front of you should belong to an alpha city.

Comparing the annexes of the earth with temples on the earth, the former is the famous temple of Baoshan, the kind of large temple with strong incense, while the latter is the Chenghuang Temple built next to the vegetable market.

"If there is danger, it should not be threatening us." Ze Luo was still quite confident here. While walking in, he used his big hand condensed from space to flatten the ruins.

Soon he pushed to the position of what Thirty-San said, "sensing large-mass Ninolo alloy", but the problem is that there is nothing here.

"Is it really underground?" Ke Lan was stunned for a moment, and couldn't help but remember the ridiculous scene of burying the warship into the ground that he had just imagined.

"Well, underground, and... very big." Thirty-san murmured - after Ke Lan flattened the ruins and the barriers were cleared, his senses became more and more acute.

"Then... dig three feet into the ground!"

He did it right away, and a big pit was dug out soon after. At about one meter deep at the bottom of the pit, a circular gate made of pure Nino alloy appeared in front of the two of them.

"This is the thing you sensed, right?" Ke Lan glanced at Thirty-san and said.

"That's right... there are words written on this door, what does it mean?"

"Nest City."
