During this rapid growth period, Tyrannosaurus Rex needs to swallow a large amount of food.

Lei Huanxi had a headache when she heard this.

This is a bit too complicated, right?

But it doesn't matter, it's boring here anyway, right?

A complete food chain needs to start from the bottom.

What was the age of dinosaurs like?

Lei Huanxi was trying hard to imagine.

Unfortunately, his limited knowledge of the dinosaur era restricted his imagination.

In the end, Xiaopang told him what to do.

In the distant era of dinosaurs, Tyrannosaurus rex was undoubtedly at the top of the food chain, and it had almost no natural enemies.

Not all animals have natural enemies. Many animals at the top of the food chain have no natural enemies at all.

However, animals at the top of the food chain generally have problems of one kind or another to avoid the expansion of the population and causing ecosystem disasters.

The first is mainly because of the low reproductive ability and the low survival rate of offspring, which limits their own number to blindly expand.

The second is the individual's lifestyle. As the saying goes, one mountain cannot accommodate two tigers. These animals at the top of the food chain often control a "territory" based on individuals.

Their different individuals are also in competition, limiting their number to expand.

If the number of animals at the top of the food chain blindly expands, it will cause ecosystem disasters. After the bottom layer is eaten, the top layer will starve to death and everyone will become extinct.

Therefore, the result of natural selection is often that animals at the top of the food chain are often not too many. They will limit their own number and will be automatically eliminated if they are not limited.

From this point of view, Tyrannosaurus Rex and Tiger are very similar, but this is not accidental.

Then, there are triceratops, allosaurus, stegosaurus, etc.

These are all things that can be used as Tyrannosaurus Rex food.

As the top large predator in the dinosaur world, Tyrannosaurus usually captures all kinds of dinosaurs that cannot beat it.

This is much easier to deal with.

Under the guidance of Xiaopang, one dinosaur species after another began to appear.

He is equivalent to restoring a dinosaur era there.

If any biologists see this now, they will definitely go crazy.

Lei Huanxi himself would never have thought that he would do such a crazy thing.

Seeing one dinosaur after another appear, Lei Huanxi really felt a sense of satisfaction.

When all these preparations were done, only Lei Huanxi was left thinking about what he thought:

Tyrannosaurus Rex!

As the image in Lei Huanxi's mind became more and more abundant, gradually, a young Tyrannosaurus Rex appeared.

Lei Huanxi almost cheered out.

Slowly, I overlooked a big problem.

The parents of Tyrannosaurus Rex should be the most competent parents in the biological world.

From the incubation of eggs, the parents of Tyrannosaurus Rex will always be with their children.

They don't leave until their children actually grow up.

However, the birth of the Tyrannosaurus Rex, which looked not cute at all, skipped the process of hatching the eggs.

Can you grow up smoothly?

Lei Huanxi came to this little guy.

The puppy Xiaofei didn't come over, but instead looked scared.

Before, because of class relations, Xiao Fei was used to becoming the king, but out of animal instinct, when the little Tyrannosaurus rex appeared in the first second, Xiao Fei knew that a overlord who was far more powerful than it was a hundred times and thousands of times stronger than it appeared.

The little Tyrannosaurus rex opened his eyes. The first thing it saw was a human:

Lei Huanxi!

The nature of animals is often particularly dependent on what you see at first sight.

They even regard the other person as their real parents.

The same is true for the little Tyrannosaurus Rex.

It opened its mouth and let out a roar that was not very loud, but made other animals shudder.

This is actually to please Lei Huanxi.

Then, it rubbed against Lei Huanxi's feet, constantly making low roars.

Is that what to eat?

Lei Huanxi was a little confused.

What should I eat for a newborn Tyrannosaurus Rex?

"Wait." Lei Huanxi said with a tough bullet, then ran towards the river.

The little Tyrannosaurus Rex seemed to understand and stayed there honestly.

Then, it raised its head and looked towards the sky.

Moreover, its body shrank back unnaturally.

Because it can feel that there is another more powerful creature in the sky.

That's, Xiaopang!

Although it can't see where Xiaopang is, it can really feel it.

At this time, the first long-necked dragon that appeared was still enjoying it in the river.

Lei Huanxi ignored him and jumped into the river.

When he appeared again, he had already caught two big fish.

He rushed to the front of the little Tyrannosaurus Rex again and placed the two fish in front of the little Tyrannosaurus Rex.

What a guy, although he has just been born, the little Tyrannosaurus Rex has a sharp teeth when he opens his mouth.

Two big fish arrived in the belly of the little Tyrannosaurus Rex in a moment.

Only then did it lie down on the ground with satisfaction and lean against Lei Huanxi's feet.

This is a complete dependency.

A real Tyrannosaurus Rex?

Lei Huanxi never thought that he would do such a crazy thing.

But at this moment, the little Tyrannosaurus Rex suddenly got up, be as afraid as he should be.

Lei Huanxi knew what was going to happen.

Little fat!

This most powerful creature on Earth is about to begin its own evolution.

Those animals that have lived here for a hundred years have become accustomed to it.

Thunder and lightning, wind and rain are shattered.

This is all made by Xiaopang.

But for the dinosaurs that just appeared in this world, they were enough to make them frightened.

The dinosaurs ran around, looking for a safe place.

But where is there really safe place in this world?

Lightning flashed across the sky one after another.

The little fat shuttled back and forth in the clouds.

That's the figure of a dragon!

Xiaopang suddenly felt that his evolution seemed to be very smooth today.

What's going on?

Is it related to the appearance of those dinosaurs?

There is only one explanation: when there are more creatures in this world, especially the more creatures closest to the dragon's era, the more helpful it will be for one's own evolution?

When Brother Huanxi imagined so many dinosaurs today, Xiaopang obviously felt it.

And Lei Huanxi on the ground also discovered this.

Xiaopang's body grew very fast today. In a short while, it grew at least half a meter.

You know, it has only grown by one meter in the past hundred years.

Dinosaur?

Lei Huanxi also thought of this at the same time.

If this is really helpful to Xiaopang, then it will be easy.

I can completely rely on my own abilities to make more dinosaurs appear here.

Or creatures that live in the same era as dinosaurs.
