Shen Cheng definitely believed that aliens had appeared on this planet.
After all, both the teleportation device and the real mirror device are veritable relics of alien civilization.
But Chen Cheng seemed to have always neglected one thing: what happened to the alien civilization that would leave its products on this planet? What was their purpose in coming to this planet?
Was it really an invasion? How could an alien civilization, possessing such advanced technology, be defeated by humans who were still recording history through carved murals?
"We speculate that the age recorded in this mural is already ten thousand years ago." Bu Cai said.
Ten thousand years ago?!
“No, if we follow the story told by the old man in the village at the foot of Kunlun Mountain, then the time does not match, unless…” At this point, Shen Cheng suddenly paused.
Unless... alien civilization has invaded this planet a second time!
"Do you still remember the Tianku?" Bu Cai said in a deep voice.
Tianku, which is the so-called "hole in the sky".
Shen Cheng nodded.
"If what the local villagers say is true, the creation of the Sky Cave is most likely the result of the second invasion of alien civilization."
Shen Cheng was still clear about this.
Because the dragon head mural told him that the hole in the sky appeared because of a product of alien civilization left here. As long as it was destroyed, the hole in the sky would no longer appear.
This time, everything fits together.
"But... did humans at that time really have the strength to rival alien civilizations?" Finally, Shen Cheng couldn't help but ask.
"The power of human unity is immeasurable. This may also be due to the problems of the alien civilizations themselves, and..." Bu Cai flipped through several A4 papers and finally found the one with the dragon head mural.
"Officer Shen, what comes to mind when you hear the word dragon?"
"...Mythology." After a moment's silence, Shen Cheng replied.
"Is there a possibility that they are not myths, but highly intelligent creatures that already exist in the world? Because of their powerful strength, and through word of mouth from generation to generation, they have become the myths in our eyes today?" Bu Cai suddenly said.
Shen Cheng was a little stunned.
"Psychics can manipulate the elements, and avian phantoms can influence minds. These are incredible things, right? But they really do happen."
Bu Cai asked again: "Officer Shen, let me ask you again, when you mention mermaids, what do you think of?"
"Fairy tale." The first thing that flashed through Chen Cheng's mind was the image of Ying Yu.
"But Yingyu does exist. If my thoughts are correct, Yingyu's race is the prototype of the fairy tale mermaid, a fairy tale that has been passed down from generation to generation and has become popular today.
As for the fantasy creatures in some of the stories we know about, most of them may have actually existed, but for unknown reasons, they disappeared from history!"
Bu Cai continued to talk: "The reason why humans were able to defeat the invading foreigners at that time may have been because of the help of these creatures. However, I think it was the power of humans themselves that accounted for the majority of it."
“…”
Shen Cheng fell silent. To be honest, Bu Cai's idea was somewhat far-fetched.
But once he connected these with what was happening now, Shen Cheng felt that Bu Cai's statement was unexpectedly reasonable.
After a while, Chen Cheng looked directly at Bu Cai and slowly said, "Old Bu, do you think... the alien civilization will invade us a third time?"
…
When Shen Cheng walked out of the Institute of Biological Sciences, his mind was still confused.
If all of Bu Cai's speculations were true, then even if Shen Cheng racked his brains, he would not be able to figure out how the humans of that era defeated those high-tech civilizations.
Is it really relying on those mythical creatures?
You know, even now, they have no way to thoroughly study the remains of those alien civilizations.
According to the old man at the foot of Kunlun Mountain, there were constant natural disasters in the western region at that time, and it was dark and gloomy. In the end, a golden dragon soared into the sky and saved them from danger.
Then... could it be a confrontation between the Golden Dragon and alien civilization?
In Shen Cheng's opinion, it seemed that Jin Long lost the battle.
The dragon head mural under the Sleeping Dragon Cliff is the best proof. The disaster caused by the sky cave still exists, but the dragon head mural can only sleep in an unknown corner. Even the task of repairing the sky has to be entrusted to an ordinary person.
Just this one sky cave has left humans helpless. If alien civilization really launches a third invasion, can humans really resist it?
Shen Cheng shook his head, getting rid of all the messy thoughts in his mind.
Now, just completing the dream law and mending the sky are enough to make Shen Cheng anxious and overwhelmed. Thinking about these things again will only add to his pressure.
Before he knew it, Shen Cheng found himself in the cafeteria.
It's lunch time now, and it's almost time for Yingyu to come and eat.
Well, there’s also Feicui Nana and the others, they should be with Yingyu.
As for Wutong... the inspection should have already started by now, and he probably won't be coming back to the cafeteria.
After getting a meal in the cafeteria, Shen Cheng glanced around the cafeteria and finally stopped his eyes on a table.
Yingyu, Feicui, and Nana were indeed together, but… there were three other people who surprised Shen Cheng.
Walking straight to the dining table, Shen Cheng sat down next to Ying Yu.
Several people who were talking and laughing at the table suddenly stopped.
"Chen Cheng!" Ying Yu was the first to react. Her brows immediately lit up with joy. Without saying a word, she threw herself into Chen Cheng's arms and rubbed against him.
Chen Cheng smiled and ruffled Yingyu's long pink hair: "Long time no see, Yingyu."
“Hehehe…”
"Wow, it's you!" Then three more people stood up suddenly, and a royal sister with long blue hair pointed at Chen Cheng and shouted.
Chen Cheng turned his gaze and said to the three people, "It seems that you have chosen to join the Institute of Biological Sciences. How are you doing in the Institute of Biological Sciences?"
These three people were the three-person deep-sea team that Shen Cheng met when he went to Hongguo.
The eldest is Yiran, the octopus Huanya; the second is Shafeng, the shark Huanya; the third is Xiaotun, the dolphin Huanya.
"I'm living a good life. Everyone is... very friendly." Xiaotun replied in a low voice with a red face.
"I think it's okay, at least not as scary as I thought." Shark Wind also replied. At least it's not like what she thought, that any old man could beat her to a pulp.
Moreover, here you don’t have to continue living the kind of survival of the fittest lifestyle you find in the deep sea, where you can’t even sleep well.
