Still alive 200 million years ago

In the vast expanse of land, the sun scorches tens of thousands of miles of wasteland. On the ancient Pangea, there are deserts, Gobis, and wastelands everywhere, turning the entire continent into a red-hot color.

And just north of the vast central mountain range that runs through the continent from east to west, with the Panocean on one end and the Tethys Sea on the other, the southernmost side of Laurasia is a huge desert that far exceeds the Sahara.

The vast Pangea cut the entire Pangea in half, and the entire Earth's climate cycle system was also cut in half. The moist sea breeze could not blow into the interior of Pangea, and the sun burned it, causing Pangea to become what it is today. of drought.

Phew! On the desolate red Gobi, a small lizard that blended in with the color of the Gobi quickly shot out its long tongue and sucked the large dragonfly flying freely in the air into its mouth.

Crack, click, click.

The chicken was crunchy and crunchy, but a little disgusting.

But the reminder interface that popped up soon turned this little bit of nausea into a cloud.

[Acquired components: Lin's three-tiered flying thin wings]

It's a pity that the source of quality is insufficient now, so there is no way to modify it in the creature editor.

The little red lizard stood on the red rock, raising its head and looking ahead with its big bulging eyes with a sad face.

Yes, if there is a human in front of him, he can see how rich the look in this lizard's eyes is.

This lizard is Xu Dong who has traveled through this ancient wilderness era.

The story started five days ago. He was bored and looking for games on the mobile game platform, and found a spore-like survival and development game called Ancient Creatures Adventure.

Brief description below:

[This is a game where you can play as a prehistoric creature and lead the race to develop and grow. Players can choose different eras and corresponding species in this era to play the game. They can survive, hunt, and develop on the stage of biological evolution hundreds of millions of years ago, and become biological creatures. Existence at the top of the chain! ]

The cover and poster of the game were very crude, and the animal modeling was in the mosaic style from ten years ago. However, the big fish eating small fish and survival and development model just hit Xu Dong's liking, so he downloaded it.

Entering the interface, this game reveals the style of a reskinned mobile game everywhere, with a shoddy interface, bad music, conspicuous krypton gold gift packs, and advertisements that pop up from time to time...

Xu Dong ignored these and entered directly. At the beginning of the game, he chose an era. Players could choose from the Cambrian, Triassic and Cretaceous. He would not choose other eras if they had to pay.

The Cambrian is the first period of the Paleozoic Era, the beginning of the Phanerozoic, about 542 million years ago to 485 million years ago. Almost everyone’s impression of the Cambrian is the Cambrian explosion of species. If you start from the Cambrian Since the beginning of the century, they have to go through a very long stage of invertebrate development. Xu Dong does not want to start with a puddle of rotten meat or a swarm of bugs.

The second option, the Triassic, is a geological era from 250 million BC to 200 million BC. It is located between the Permian and the Jurassic. It is the first era of the Mesozoic Era, sandwiched between two mass extinctions. era.

In the early and middle Triassic period, Pangea was arid and hot, with Gobi and desert everywhere. After the Carnian flood event that lasted two million years, the entire continent turned into a tropical rain forest.

A new era means new changes. The Synapsids that dominated the Permian Period withdrew from the stage of history and became an insignificant role. The kingship of the pseudosuchians fell, and the new king began to rule for 130 million years.

The Cretaceous was the last era of the dominance of this overlord, starting from 145 million years ago until the judgment from the sky 66 million years ago, which ended the glorious age of dinosaurs.

From the perspective of living environment, Xu Dong must have chosen the Cretaceous. After all, there is no shortage of food and ecological niches. However, the Cretaceous has a flaw in that there are too many organisms, too many competitors, and too much pressure. Xu Dong doesn't like it. As soon as they came up, they competed with others for their ecological niche.

So he chose the beginning of everything, the Triassic Period 250 million years ago. Although the environment was harsh, the ecological niche was empty. Everyone was on the same starting line. Who was afraid of whom when starting from scratch.

After choosing the era, it is time to choose the race. The three major races that Xu Dong can choose are the Zerg, the Dragon (Sauriformes) and the Orcs (Synapsida). The others are like spondyloids, fish, molluscs, and fungi. Classes and other races must be paid to unlock.

The Zerg were the first creatures to step onto land from the ocean and were one of the overlords of the Paleozoic Era. Although they have lost their protagonist aura after being targeted by several versions of the planet's natural system, they still expanded their race with their tenacious vitality. To all the bottom ecological niches of the earth.

There are two advantages to choosing Zerg. The first is that you don’t have to worry about food and drink. After all, bugs can eat anything. The second point is that it has strong vitality. It has resisted five mass extinctions of species and has not perished. It has survived well into the modern era, and the number of races is the largest on earth.

But the shortcomings are also obvious. They are at the bottom of the ecological niche and cannot be supported at all. They can only be reduced to food for other races. Moreover, they are disgusting in appearance. He will just pass the Zerg.

The Orcs, the overlords who ruled the Permian Era, at that time, the Dragons were just the food on the Orcs' lips. However, after the mass extinction at the end of the Permian, the tides turned, and the Dragons completely suppressed the Orcs. It was pitiful for the weak and helpless people. The orcs can only live underground for hundreds of millions of years.

The Orcs in the early Triassic actually had some advantages. If Xu Dong chose the Orcs, he might have a chance to make a comeback. After all, the Orcs in the future would evolve into the most terrifying creature on earth, the terrifying erect ape!

But this is a game after all, and Xu Dong is quite interested in dinosaurs, so he chose the dragon family.

After choosing the major category, we are not done yet. There are three branch routes under the dragon family, including lepidosaurs, pseudosuchians and ornithopods.

Obviously, as a skin-changing game, the powerful pseudocrocodiles of the Triassic and the invincible ornithopods in the future have to be unlocked with money. How could Xu Dong be cut off by this inferior mobile game that he just played for a few minutes? If you eat leeks, a lizard will just become a lizard. It doesn't mean that it can't evolve into a dragon.

When he pointed at the scale dragon option, the newly purchased Huamiguo mobile phone in his hand suddenly emitted a dazzling white light, which stung Xu Dong's eyes with tears and could not see anything. The white light enveloped Xu Dong and completely engulfed him in an instant. .

When he regained his sight again, he had arrived in this extremely hot and barbaric era. Yes, it was the extremely dry Triassic that gave rise to a brand new species, the Gobi Red Lizard.

The full name should be Animalia - Chordata - Vertebrate subphylum - Amniotes - Sauriformes - Dipsera - Dragons - Lepidosaurs - Lepidosaurs - Squamata - Desert Sauria - Red Lizardidae - small red lizard.

Xu Dong was completely confused when he first traveled through time. After more than 20 years of bipedal walking, he couldn't even crawl on all fours at first. Fortunately, he had just hatched from an egg, and the same kind of people like him couldn't even walk. There are a lot more.

What is even more shocking and desperate is that it is a strange era, a strange environment, a strange species, and most importantly, he is not even a human being. Is it really like a certain game?

Starting with a lizard, evolution depends entirely on swallowing?

While Xu Dong was thinking wildly, a huge black shadow enveloped them little lizards. Xu Dong looked up in surprise, only to find that it was a little Gobi red lizard that was several times larger. The power of his bloodline made him understand that this was theirs. Mother.

The mother of the little Gobi red lizard came back with an insect about the same size as Xu Dong's body in her mouth to feed her babies.

When Xu Dong first saw this disgusting insect, he refused to open his mouth even if it killed him, but soon his hungry body kept sending signals to him.

Hungry.

So hungry!

Want something to eat!

Xu Dong finally succumbed to his body's functions, closed his big eyes and bit off a section of the insect's trunk.

Click, click, click.

As long as you don't think about the appearance of the food, it actually tastes pretty good.

[Acquire 1 source of essence. ]

? ? ?

What is it? Xu Dong stopped opening and closing his big mouth. The little red lizard's simple brain could not allow him to eat while thinking.

The sound came from above him. The little red lizard hadn't evolved ears yet, but that's what he felt.

So I raised my head and looked up, and a familiar line of simplified Chinese characters appeared on it.

[Essence+1]

Xu Dong is not stupid. After playing games for so many years, he knows the routines of the game very well. What's more, the mobile game he was playing before time travel clearly introduced what the essence is.

Similar to the DNA points in the simulation game Spore that I played a long time ago, you can modify the appearance of your race in the race editor, add and delete components and weapons.

At the same time, it can also strengthen the physical attributes outside the editor.

How could Xu Dong not be tempted by such a thing? Suddenly, he stood out among a group of brothers who could not walk steadily and could not bite. He ate most of the insect by himself and gained 1 point of source quality again. .

This insect cannot have even 1 point of essence based on its size, but it is probably a novice reward. Xu Dong actually got two points of essence while solving the problem of food and clothing. Xu Dong immediately added one point to this attribute point. On Agility.

In this world, no martial art is strong but fast. He still agrees with this statement.

After feeding the little red lizards, the mother took her litter of seven or eight little red lizards to the large tribal settlement.

The Gobi little red lizard, a population that split from the desert red lizard, was already extinct in its previous life. Not to mention the little red lizard, even the desert red lizard has not been discovered by humans. The five mass extinctions have buried too many lives. Even more traces of their past existence have been annihilated.

A small variant like the Gobi Red Lizard, whose number is only a few thousand, may not even have a chance to be wiped out by the mass extinction of species, and it will die in the harsh climate, scarce food, and heavy rains of the Carnian period.

The little red lizard is smaller than the red lizard. Unlike the desert red lizard, they live in a small piece of Gobi and make a living by preying on insects. They can also be considered as occupying a small territory in the Gobi ecological niche.

Natural selection, survival of the fittest, the evolution of the little red lizard has chosen a shrinking system, which means that it is ready to develop in the direction of Gou.

Nature has shaped the environment of the entire planet, and it also comes with a variety of ecological niches. As long as there are no natural disasters, these ecological niches will soon be occupied by various creatures.

Large-bodied animals are at the commanding heights of their ecological niche and can easily obtain food and can prey on other animals. However, they also have fatal shortcomings. Their huge size means that they need a lot of food to maintain body nutrition, which makes them face Natural disasters are very vulnerable.

As the body size becomes smaller, although the ecological niche will sink, it also means that the food intake will be reduced, the pressure of survival will be lower, and the ability to survive will be stronger.

Xu Dong looked at the endless Gobi, and he still recognized the race at the beginning. In this year of frequent natural disasters, only Gou is the king.

Small Theater of Paleontology: Explain the classification of Sauromorpha. I won’t mention the true crawlers at the front, Lumer’s large nose, and the number of temporal pores. Anyway, the mainstream ones are still divided into lepidosaurs and archosaurs. According to Baidu Encyclopedia The classification of Sauromorpha is into five orders: Crocodiles, Rhythrocephala, Squamata, Turtles, and Saurogenses. Squamata and Rhythrocephala belong to Lepidosauriformes, the ancestors of modern lizards and snakes, while others The orders all belong to the subclass Archosauriformes, which include dinosaurs, pterosaurs, crocodiles, turtles and the like.
