But dragons fighting in the same cave are completely different. They never roar, only the sound of bodies hitting each other.

Su Xing had a vague guess.

Perhaps they were not fighting as he understood, but were engaging in some kind of dragon communication that only cave dragons could have.

Two days later, Su Xing discovered that there was another stone in the egg nests of the two white dragons.

It is still an oval white stone, exactly the same as the previous one. When they are placed together, even the size is almost the same.

Not only were there more stones in the white dragon's egg nest, but also in other cave egg nests where two dragons lived together, stones that had not been seen before were also appearing one after another.

The stones have different colors and appearances, some are rounder, some are longer, and some have spotted patterns.

The only similarity is that they are placed in the groove in the center of the egg nest, as if it is not a stone but an egg.

……Egg?

Are those dragon eggs?!

Su Xing figured it all out in an instant.

Such eggs can only appear in caves where two dragons live together, and these only appear after a "fight".

As expected, those dragons were not fighting, but making eggs.

So...do you have to have two dragons to lay an egg?

No wonder the black dragon mother never laid eggs.

Su Xing realized.

As for why the black dragon mother doesn't live with other dragons, Su Xing thought of two reasons.

One is because of him.

The mother already has him as a cub. If other strange dragons join in, with the fighting power of adult dragons, he is likely to be hurt or even die.

Mother Black Dragon is here to protect him.

As for the second reason...

Although there are many kinds of dragons in volcanoes, with more than a dozen different species ranging from appearance to scale color to body shape, dragons living in the same cave all look the same or are very similar.

Like white dragon and white dragon, red dragon and red dragon.

Even the colorful feathered dragon living above their cave had a roommate with a similar-sized feathered dragon, but the color was relatively dull and not as colorful.

As for the black dragon mother... they have been living in the volcano for more than ten days. Dragons have joined one after another, but no dragon similar to the black dragon has appeared.

There is no similarity in appearance, color or body shape.

Isn’t the Black Dragon Mother branch going extinct?

Su Xing was shocked, and immediately comforted himself: It's okay, at least the mother has him as a cub.

It's just that he looks a lot different from Black Dragon's mother.

But he is still young now, it will be the same when he grows up...right?

·

As the days passed, there were more and more eggs of different shapes in each nest.

After discovering that the black dragon mother had no other kind and could not lay eggs, Su Xing fell in love with staying at the entrance of the cave to observe other dragons.

Because he lived on the lowest floor and couldn't see much, Su Xing gradually fell in love with visiting the Feather Dragon's house upstairs.

At first, I took Black Dragon’s mother with me.

The two feathered dragons huddled in the corner, not daring to have any objections to their visit, not showing any of the ferocity they had when they wanted to bite him.

Later, Su Xing went to visit alone, and Black Dragon was waiting for him to come back at the entrance of the cave downstairs.

The feathered dragon's sense of smell was blunted, but its brain was not stupid. It knew what not to mess with, so it allowed the little fur ball with no attack power to stay at the entrance of its cave.

After gradually becoming familiar with each other, even if Su Xing approached their nest, they would not react at all and continued to sleep alone or groom each other.

Perhaps they found that Su Xing's small mouth was hard enough to crack a nut, and naturally they couldn't peck through the hard dragon egg shell.

After this period of observation, Su Xing discovered that large dragons living near magma would not incubate their eggs themselves, but would just place the eggs in the nest and let the geothermal heat hatch.

Just like these two feathered dragons, they left the eggs in the nest and ignored them, let alone lay down to hatch them.

Also, with their huge and heavy bodies, if they lay on top of them, the egg nest would collapse in an instant and the dragon eggs would be crushed.

The small dragons that live on the platform of the volcano will choose to hatch themselves because the temperature at the top of the volcano is not enough and they are light in weight.

Therefore, two large dragons can go out to hunt together, while small dragons need to eat alternately.

When the male dragon goes out to hunt for food, the female dragon stays in the nest to incubate the eggs. When the male dragon comes back after eating, he takes over the job of incubating the eggs, and the female dragon goes out to hunt for food.

·

One afternoon, the dragons had just finished hunting and returned to their nests, when suddenly the sound of many wings flapping came from the sky above the crater.

Su Xing stood at the entrance of the cave and looked up, only to see a large group of strange dragons pouring into the volcano.

Eh? Are there any new members coming?

Why are so many here at once today? There are almost more dragons than there were in the volcano.

I don’t know if there are any similar black dragon mothers among them.

Su Xing carefully identified it, but before he could see it clearly, the black dragon's mother came to the entrance of the cave and pushed him inside.

At the same time, the roars of various dragons sounded, and all the dragons roared, seeming to intimidate and expel them.

Immediately afterwards came the sounds of bodies colliding, biting, and screaming.
