As a high-level demon beast, there is no shortage of spirit demons and even advanced existence of the Xuan Demon level in the clan, but the demon is not good at construction after all, and this neat nest with obvious carpentry traces obviously cannot be built by the Bloodwing Bird itself. Then, the only thing left is the wonder of God Bless.

"Isn't that weird?" asked Tianyou.

"Isn't it strange?" Bai Bingyu also asked rhetorically.

"Bloodwing birds treat me as a companion, they will even take the initiative to fly down to save me when they see me attacked, and I will run here every time I encounter a monster that I can't shake off, they are my last line of defense. If it's you, don't you like to have more allies?"

"So you started raising the Bloodwing Bird?"

"I can't say it's raising. Tianyou led Bai Bingyu over. "I'm just trying to make this group bigger. A single Bloodwing Bird is actually very fragile, in order to prevent me from messing with a terrible monster every time, the more Bloodwing Birds as an ally, the better. ”

"You can increase the number of bloodwing birds by making them nests?"

"Of course, it's more than that. As he spoke, Tianyou pulled Bai Bingyu and walked to a small nest closest to the entrance of the cave. It's amazing that the blood-winged bird that was originally lying in the nest actually took the initiative to stand up after Tianyou approached, and then vacated its place. Bai Bingyu's gaze had always been on the Bloodwing Bird, she had never been so close to the Bloodwing Bird. The size of these guys is actually not much smaller than a person, and after the wings are extended, they are extremely huge, usually Bai Bingyu has only seen flying in the sky, this kind of face-to-face contact is really the first time.

After staring at the blood-winged bird for a while, making sure that it had no intention of attacking, Bai Bingyu's gaze turned back to the nest.

The nest was actually a square wooden box fixed to the rock at the bottom of the cave, with a layer of hay at the bottom of the box, and seven or eight red blood-winged eggs lying on a soft straw mat. At this time, Tianyou was picking up the blood-winged bird eggs one by one, shining them in the sunlight at the entrance of the cave, and then put three of them back, and then threw the remaining ones one by one to the adult blood-winged bird.

In Bai Bingyu's surprised gaze, the blood-winged bird that was still incubating eggs just now opened its mouth and swallowed the eggs thrown to it by Tianyou one by one.

What's going on? That's its own egg! Bai Bingyu's eyes widened, and he couldn't understand what kind of behavior this was. Looking at the Bloodwing's previous actions, it was obvious that it had deliberately asked Tianyou to pick the Bloodwinged Bird's eggs, but why was this? Why did it eat the eggs that were still hatching just now?

Bai Bingyu was puzzled, but Tianyou seemed to know what she was thinking, and had already begun to explain: "At first, the blood-winged birds laid eggs on the ground and then hatched them. You also know that the ground is cold, and even with the physique of a demon beast, it is very difficult to hatch the young blood-winged birds, which not only takes a long time, but also has a very low hatching rate. In addition to eggs that are born with problems, there are also some that will roll out of the nest due to the unevenness of the ground and then break. So in general, the survival rate of blood-winged birds is very low. ”

"And what are you doing here?"

"I helped them build a fixed nest with a baffle around it so that the eggs wouldn't roll out again. Planks and hay insulate the icy ground, which increases survival rates and speeds up hatching. However, more than half of the eggs of the blood-winged bird itself are problematic, and they cannot hatch with the original chicks, and the female blood-winged bird cannot lay too many eggs at one time, otherwise it will not hatch. So every time I have the opportunity to come over, I pick them out. The unhatched ones are eliminated directly, and the blood-winged bird will lay new eggs within a few days to make up the number. The dead eggs that cannot hatch are simply eaten by the female blood-winged bird, and they can also supplement nutrition to make the next batch of eggs of higher quality. Anyway, the monsters don't have that many moral constraints, and they don't mind eating their own eggs. ”

In fact, this situation is very common in the animal kingdom. It is said that tigers do not eat their children, but in fact, many wild beasts will eat some of the young beasts when they are extremely short of food, because they can't be raised anyway, so it is better to keep the big ones, which is more conducive to the reproduction of the population. Even the cubs that have grown up can be eaten, let alone dead eggs that can't hatch in the first place.

Beasts are like this, let alone monsters. These guys are much more cruel than the beasts. However, although the blood-winged bird is ferocious, it is extremely harmonious within the group. After hatching, the young birds will be fed and protected by the whole herd, and the injured adults can also be cared for by their peers, and they can recuperate without worrying about food and clothing. Adult blood-winged birds are even more offensive and defensive allies, and one side is in trouble and all sides are supporting. The reason why Tianyou can be protected by other blood-winged birds is because blood-winged birds have this habit of protecting their companions. The only thing he didn't figure out was why the Bloodwings thought he was their companion.

Bai Bingyu didn't understand this strange pattern, but there were too many magical places on Tianyou's body, and she was already a little numb.

Under the guidance of Tianyou, Bai Bingyu even learned how to use the light transmission of eggs to identify whether it was a stillborn fetus. Together, the two of them quickly helped identify most of the blood-winged birds here. However, instead of giving all the eggs to the blood-winged birds, Tianyou deducted a few and put them in his pocket. The bloodwinged birds could see it, of course, but they didn't react to it in the slightest.

Tianyou was about to leave after checking all the eggs, but at this time, a slightly different cry came from inside the cave. Bai Bingyu was startled, thinking that the Bloodwing Birds were going to attack them, but when he looked back, he saw that most of the Bloodwing Birds were still lying on their stomachs in the nest, without the slightest intention of attacking.

Tianyou suddenly came up with the source of the voice, and decisively led Bai Bingyu over. This is a blood-winged bird's nest set up at the highest point of the cave, which seems to be made by Tianyou, but it is several times larger than the ones below, because the winged bird inside is not an ordinary blood-winged bird.

When he saw this winged bird, Bai Bingyu even began to breathe rapidly. She had always felt that she was a very calm person, but now she couldn't control her heartbeat.

In the huge nest squatted a giant winged bird that was more than three times the size of the other bloodwinged birds, and its feathers were no longer bright blood-red, but silvery-white. This is the Silver Winged Bird, which belongs to the same class of demon beasts as the Bloodwing Bird. There is no flock between different colored winged birds, and it is normal for blood-winged birds to mix with other winged birds. There are various explanations for this in the outside world, and there is no description of this in the "Demon Record", but Tianyoujue's Blood-winged Bird should be the basic race, and all the Winged Birds are the advanced forms of the Blood-Winged Bird, just like the monks choose the direction of cultivation, the Blood-Winged Bird should be able to choose the direction of evolution.

The silverwing bird is a very rare category of winged birds, Bai Bingyu and Ben don't know how to rank, and there is no record of the silverwing bird in "Demon Record". What's more, the eyes of this silverwing bird are already green, this is still a silverwing bird that has advanced several times, although the level cannot be determined, but it will not be lower than level 100. What kind of concept is this? Level 30 and above are called spirit demons, level 60 and above are called Xuan demons, and level 90 and above are big demons. Bai Bingyu himself is only equivalent to a level 32 demon beast, and he can only have a tie with the lowest-level spirit demon, but this has emerged as a monster of more than a hundred levels, as long as it wants to, it is a trick to deal with them!

There was such a terrifying monster in this Qingyuan Mountain, Bai Bingyu felt that his heart was about to rise to his throat.
