"Brother He!" Luo Jiaqi hurriedly jumped over, quickly picked up He Jun and patted him on the back, until He Jun eased up this momentum, then stopped and asked, "What should we do in the future?" ”

Since He Jun knew what kind of place this was, Bacheng also knew the situation of this era, so he had the initiative, and he no longer had to venture out of the community like a blind elephant to explore the situation nearby.

"What will I do next?" He Jun's face was bitter, "You don't have to do anything, stay here and wait." ”

"What are you waiting for?" Locke asked in surprise.

"Wait for the crossing." He Jun's face can no longer be described as difficult, "If we go back before we starve to death, we will be saved, otherwise, we will starve to death together." ”

Locke was taken aback: "It's not so serious, is it?" ”

He Jun said without hesitation: "It's more serious than you think." ”

Locke gasped: "There's nothing to eat in this place?" ”

He Jun sighed faintly: "The Cambrian is the beginning of the Paleozoic Era, there were not many organisms on the whole earth before the Cambrian, and after the Cambrian, the earth's organisms appeared on a large scale, this place is not uneaten, the problem is that the animals and plants of this era all live in the sea, unless we can find the sea, otherwise...... Alas! ”

Although He Jun didn't say what would happen otherwise, Luo Jiaqi understood the meaning, and he asked unwillingly: "Then can't we look for it?" What if the beach is not far from us? ”

"Find? How to find it? He Jun asked rhetorically, "The shape of the continent in this era is completely different from that of modern times, even if we know where we are, we don't know which direction to go to find the sea!" ”

Locke Jiaqi sat down on the edge of the bed like a leaky ball, which Cheng wanted to sit on Liangzi's feet, and Liangzi in his sleep screamed miserably, and sat up on the ground: "Douzi, what are you doing!" ”

Luo Jiaqi died and cried like her parents: "Liangzi, this time it's really over, let's die!" ”

Liangzi pulled the almost broken foot out from under Locke's buttocks, carefully moved it twice, and gritted his teeth and said hatefully: "You can't wait for that day!" ”

Luo Jiaqi was anxious and angry: "I'm not joking with you, we're finished." As he spoke, he picked out the key points of He Jun's previous judgment and roughly said it.

Liangzi was stupid when he heard the whole person: "Brother He, you can't be mistaken, right?" I've seen in the novel that there was a Cambrian explosion of life, didn't the creatures of the sea come ashore at this time? ”

"Of course not!" He Jun affirmed, affirmed and firmly said, "The life that erupted was all marine life, and the first plants to come ashore appeared more than 400 million years ago...... That is, at least 100 million years later, if you think about it, if plants don't go ashore, what do animals eat and drink when they go ashore? ”

The principle of survival of living organisms is that there are no "producers" and no "consumers", so it will take at least 100 million or even 200 million years for the organisms that have been living in the water to gradually move to land.

Thinking about this, it makes sense why the neighborhood is deserted.

"So what do we do? Just sit and wait to die? Ryoko panicked for no reason.

Death itself means fear, and what is even more terrifying is that you know that you are approaching the abyss step by step, but you can't control your steps, and you can only watch yourself step by step on the road to death.

He Jun was silent for a moment, and said hesitantly: "Maybe there are things to eat in the rivers, but the neighborhood is full of Gobi, and there is no river at all, and there is no vegetation on the land in this era, and seasonal rivers must exist, but it is difficult to say whether there is a stable water system." ”

He had read a lot of information, but most of them were general descriptions of a certain geological age, and he did not expect the community to cross again, so he did not carefully study the detailed characteristics of each geological age, but only knew a general situation.

The geological age is often tens of millions of years, and according to He Jun's understanding, the Cambrian period seems to have lasted between 50 million and 60 million years.

You know, the time gap between the extinction of the Cretaceous dinosaurs and the modern era is only 65 million years, you can imagine how much the earth changed throughout the Cambrian period, such a long geological age, how can those few sentences on the Internet explain clearly?

Moreover, all modern data are based on speculation from geological research, and there is absolutely no small error with the real situation.

Ryoko, who was not good at all, seemed to have been drained of all his strength, and he was stunned and speechless.

Locke slammed his fist on the head of the bed angrily: "Again and again, why did you cross over?" Why did you travel to this hellish place? Why can't you stay in the modern era? Why! ”

Ryoko said in a low voice, "I also want to ask what is the reason for all this." ”

"Whatever why, we're all here, and if I'm not mistaken, we'll only need to hold on for two hundred hours before we can wear it again." He Jun also has the same question in his heart, but Luo Jiaqi and Liangzi's emotions are not very stable, he is the oldest, and he can't mess with himself at a critical moment.

Speaking of this, he paused and barely showed a smile: "We should be glad that although the Cambrian period is early, at least there is oxygen in the atmosphere, if we are directly thrown forward for an extra billion 800 million years, we will suffocate people to death, what are you talking about insisting on or not insisting?" ”

The earliest organisms on earth were all anaerobic organisms, and He Jun did not know when phytoplankton capable of photosynthesis appeared and when the oxygen content in the atmosphere began to increase.

Luo Jiaqi and Liangzi were stunned at the same time, and looked at each other for a while.

What happens if you throw a person into a low-pressure environment without oxygen? Just thinking about it makes people shudder.

Ryoko said in horror: "If you wear it back in a few days, I won't stay in the community for another second if you kill me!" "The community has crossed twice, and no one can guarantee that it will not cross a third time.

The first time it traveled more than 200 million years, and the second time it traveled more than 500 million years, according to this calculation, wouldn't the third time travel back to more than 700 million years ago?

Such speculation is reasonable.

From its birth to modern times, the earth has experienced a total of 4.5 billion years, and in these more than 4 billion years, the environment suitable for human life has accounted for only a fraction of it.

Luo Jiaqi nodded heavily: "I won't stay for a second if I am killed!" ”

He Jun smiled bitterly: "If the official knows that the community can cross the second time, he will definitely have to withdraw people from the community and isolate them again." ”

As soon as the words fell, he was awkwardly wrapped in a cold air, and opened the door with a stainless steel steamer and entered the bedroom: "Give me a bottle of water, I cut some jerky, let's boil some meat porridge and drink!" ”
