Chapter 28: 6300 million years of extinction cycle, the dry season has officially arrived! (Test drive, please read on)
“Is this the future?”

Chu Xu, who finally woke up from the extremely real dream, muttered to himself.

This is probably the so-called "curse of knowledge" - when you already know that something is going to happen, you can't imagine not knowing it.

In his previous life, Chu Xu had studied the mass extinction of dinosaurs in depth, and combined several other mass extinction events in Earth's history to come up with a rule:

Biological extinctions show an average periodicity of about 6300 million years.

The first was the Cambrian-Ordovician extinction event, the first mass extinction event on Earth, in which more than 80% of species disappeared.
The second is the Ordovician-Silurian extinction event, when about 85% of species became extinct due to global cooling and a sharp drop in sea levels.
Next was the Devonian-Carboniferous extinction event, when the global climate cooled further and sea levels continued to drop, causing another 70% of species to disappear.
Then there was the Permian-Triassic extinction event, the most severe of all mass extinction events, in which 96% of species, including trilobites, the dominant species that dominated the Earth in the Paleozoic Era, became extinct.
This was followed by the Triassic-Jurassic extinction event, in which 76% of species disappeared, and dinosaurs became the dominant species of the Mesozoic Era.
Finally, there is the Cretaceous-Paleogene extinction event. Due to factors such as asteroid impacts and volcanic eruptions, 70% of species such as dinosaurs, pterosaurs, and mosasaurs became extinct, and angiosperms, mammals, and birds became the dominant species in the Cenozoic era.

There were six mass extinction events, and there were also many smaller extinction events in between, such as the collapse of tropical rainforests at the end of the Carboniferous period and the end of the Jurassic period.
The cycles between these events, big and small, are about 6300 million years, which is roughly the length of time of the basic unit of geological history - "era".

It just so happened that Chu Xu lived at the end of the Cretaceous period, which was the end of the 6300 million-year cycle. It is not clear whether to say it is lucky or unfortunate.

"There's no need to think so much, just live well now."

Chu Xu was too lazy to worry about what might happen next. If today was the end of the world for dinosaurs, then he must witness this historical moment in order to solve the extinction of dinosaurs, which was known as one of the top ten unsolved mysteries of the world in his previous life.

What's more, with the system at hand, as long as Chu Xu continues to evolve, what does a mere meteorite hitting the earth matter?
It is not impossible to transform into One Punch Man, blow up the meteorite with one punch and save the dinosaurs. This may cause great changes in the subsequent biological history. Dinosaurs will continue to dominate the earth, and it is not certain whether humans will appear.

……

Time flies, and another month has passed in the blink of an eye.

The dry season has officially arrived in the Laramid subcontinent. Months of scarce rainfall have caused the forest vegetation to wither away and the lakes and rivers to dry up.

In addition, Chu Xu could see with his naked eyes that there were fewer and fewer prey within the territory.

Medium and large herbivorous dinosaurs have begun to migrate collectively, heading from north to south and from west to east to the humid western interior seaway of North America.

Because of the rivers flowing into the sea, a large area of ​​coastal wetlands and delta plains have been formed in that area, with rivers crisscrossing and lakes dotted around, making it the best place to go during the dry season.

At the same time, carnivorous dinosaurs would also migrate along with the herbivorous dinosaurs.

Such spectacular migration scenes often occur on the East African savannah in later generations. They are all actions that animals have to take in order to survive, and it goes without saying how dangerous they are.

Over the past month, hunting has become increasingly difficult for both Long Ma and Chu Xu. It's not because their hunting skills are not good enough, but because there are fewer prey.

A skilled cook cannot cook without rice. No matter how good their hunting skills are, how can they hunt without prey?

So it is obvious that the Mother of Dragons has been considering migration in recent times. She often goes out to patrol her territory, confirm the movements of animal populations in the territory, and prepare for migration.

The only thing that worries her is that the migration journey is very long, and it takes thousands of kilometers at a time. Can her three little Tyrannosaurus Rex survive? Long Ma is naturally very relieved about her eldest son, but it is different for Long Yue and Liu Xing.

One's own physical condition is one thing, and the uncertain threats from the outside world are another. We must be extremely cautious.

On the other hand, Chu Xu was also busy preparing for the possible large-scale migration that might follow.

Over the past month, he has been using a special smoking process on the raw meat of the prey he hunted.

First, tear the raw meat into small pieces with your claws, then dig a hole and build a bonfire, then cover the flames with hardwood to prevent incomplete combustion and produce a lot of black smoke, and finally hang the torn meat strips above the thick smoke for smoking.

Smoking is done for several days until the meat is completely blackened, and the simple smoked meat is ready. Its shelf life can be up to three months.

Of course, even if it is carrion, Tyrannosaurus Rex can still eat it directly. They have a powerful digestive system and immune system that are enough to digest carrion and are immune to many pathogens.

Coupled with the well-developed olfactory nerves of Tyrannosaurus Rex, many later paleontologists even believed that it was a scavenger.

However, Chu Xu currently finds it difficult to accept eating rotten meat. Unless he is really about to starve to death and has no other choice, there is no need to eat rotten meat.

After hunting for most of the day today, Chu Xu didn't see any suitable prey, so he had to go back home and visit his "secret base" where he made and stored smoked meat.

The secret base is actually an open space in the core area of ​​Long Ma's territory. There is a homemade smoked meat grill made by Chu Xu. Thick black smoke rises from the blazing bonfire, which smokes the meat hanging on it to a black and red color, and then a shiny red color.
The meat becomes firm, delicate and chewy, and the aroma wafting from it is so fragrant that it can be smelled from miles away.

It’s just that because this area is the core territory of the Dragon Queen and has the scent of an adult Tyrannosaurus Rex, ordinary carnivorous animals would not dare to approach even if they smelled the aroma.

There is also a tall and sturdy sycamore tree here. Chu Xu dug a deep tree hole in its trunk and blocked it with a stone of similar size.

The dry and airtight tree hole is where Chu Xu stores the smoked meat.

"what's the situation?!"

However, today when Chu Xu came to his secret base for inspection,
However, he found that the smoked meat grill he had spent so much effort to make had fallen apart, the campfire had been extinguished, and the unfinished smoked meat on it had disappeared!

There were a lot of messy three-toed theropod footprints and even scattered feathers left on the ground, indicating that this theft was definitely a gang crime!
