At the moment when Muyang picked off the Immutable Stone, a dazzling white light instantly enveloped Bibi Bird's whole body, and his body also changed.

Wrapped in white light, the body of the bird gradually grows larger, and the feathers on its head also become longer. After a while, as the white light on Bibi Bird's body stopped abruptly, the original Bibi Bird was gone, and an eagle appeared in front of Mu Yang.

The shape of the eagle is very similar to that of the bird, except that it is larger, has a wider wingspan, and shorter claws, like an eagle. It has brown feathers, cream color from face to abdomen, inner and outer tips of wings, and black around its eyes.

The feathers on the top of its head are red on both sides and yellow in the middle, and they grow so long that they can flutter in the air. The fan-shaped tail feathers are red, and the long claws glow with cold light, and you can see that they are unusually sharp at a glance. After evolving into an eagle, his feathers became gorgeous and his wings became stronger. At this time, his eyes were also sharper, and with his stronger and stronger body, a temperament that Bibi Bird did not have, appeared on Bibi Eagle's body for the first time.

"Beep~"

Bibi Niao first looked at his body, then leaned over with his high chest and rubbed intimately against Muyang's body.

Mu Yang gently touched his head, happy for his evolution.

Finally, there is a mount!

Mu Yang looked at the eagle who was only half a head lower than him, and couldn't help but think in his heart.

Muyang's eagle is stronger than other companions when it is a bird, and it is the same after evolving into a bird, which is 1.7m tall.

This is big enough for one person to ride, and there is no need to let Bibi Bird catch himself to fly as before, to be honest, every time he flies, Muyang's shoulder will ache faintly.

"Bibi, ah no, Bidiao, take me to the still water mountain range outside the Sun and Moon City, let's see how much your strength has increased after you evolved."

Muyang said to the eagle beside him.

After breaking through twice the speed of sound, Bibi Bird has stepped into the threshold of quasi-king. After evolving into a competition, the strength must have been enhanced, but I don't know what level it has reached.

"Beep~"

The eagle spread his huge wings, and after Muyang grabbed his back, his wings shook and flew into the air with Muyang.

A few crisp birdsong came, so that Mu Yang couldn't help but look to the side, some flying elves such as Bobo, Doudou Pigeon, Mukel and other types appeared in Mu Yang's field of vision, and the cool breeze blew Mu Yang's cheeks, making Mu Yang couldn't help but feel comfortable.

"Bidiao, slow down a little faster, I want to see how fast you evolve."

After enjoying this comfortable feeling for a while, Mu Yang took a deep breath and said to the eagle under him.

After hearing Mu Yang's words, a serious look began to appear in the eyes of the eagle, and at the same time, a film condensed by flying energy also covered Mu Yang's body.

"This energy film ......"

After the energy film appeared, Mu Yang was a little shocked to find that this energy film was much thicker than the previous thin protective layer, and its defensive power was completely different.

"Beep~"

After completing these, the speed of the eagle began to increase rapidly, and with such a burden as Muyang, it broke through 1.5 times the speed of sound in an instant.

It's not that it can't be faster than the eagle, but with the ability of the current energy protection layer, at most, it can protect Muyang from damage at this speed. After evolving into a bird, Bibi Bird has already broken through his previous limits, and his potential has been liberated again, and he has gone to a higher place.

With the super speed of 1.5 times the speed of sound, it didn't take long for Bidiao to leave the City of the Sun and Moon with Muyang and come to the periphery of the Stillwater Mountain Range outside the City of the Sun and the Moon.

After reaching the outskirts of the Stillwater Mountain Range, the eagle's eyes stared down from time to time, as if they were looking for something. After a while, the sharp eyes of the eagle seemed to have noticed something, and suddenly flew in a certain direction.

When he reached his destination, he slowly landed downward, and when he reached the ground, Muyang jumped off his back and took a slight look at his surroundings.

"It's okay here, and there are relatively few elves around, so it shouldn't be disturbed."

After looking around, Muyang nodded at the carving.

"Then let me see how strong you have evolved into a carving."

But only a moment later, Mu Yang's face suddenly turned positive, and he said to Bidiao.

"Compare the eagle, make a flash of light."

"Beep~"

The eagle first moved its muscles and bones, and then instantly turned into a white lightning bolt, rushing into the distance at an unprecedented speed.

"This speed ......"

When Muyang saw the speed of the eagle, he couldn't help but be a little surprised. Without using a tailwind, just high-speed movement and a flash of light, it was possible to reach twice the speed of sound!

Although because he has just completed his evolution, he is not yet fully familiar with his body, so he is still a little unskilled. But this kind of unproficiency is nothing at all, and it only takes some time to get used to it, and you can get rid of its influence on you. It only takes one afternoon for the eagle to be in complete control of his body.

"Compare the eagle, with a tailwind."

At this moment, Mu Yang seemed to have thought of something, and hurriedly asked Bidiao to use Shunfeng.

"Beep~"

A violent whirlwind blew from the side of the eagle, and the speed of the eagle skyrocketed again, reaching four times the speed of sound.

Before using the tailwind, the eagle flew between the mountains and forests with ease. But these changed after the Eagle used a tailwind and reached four times the speed of sound. His body also gradually showed signs of being uncontrollable, and once facing the big tree in front of him, the eagle even almost hit it, and turned a big circle to avoid it. All this made Mu Yang, who was watching on the ground, frown.

"Whew~ It's okay, although it's true that it's a little uncontrollable, but it's not as bad as I thought, and then this phenomenon can be gradually eliminated through hard training."

After carefully watching the situation for a while, Mu Yang's frowning brows gradually relaxed.

Because after using the tailwind, although it is not possible to achieve complete control and flexibility as before. But it's not like that fast dragon, completely uncontrollable, knowing the rampage. You can still control yourself to a certain extent, and if you go through some special training in the future, there is a great possibility that you can achieve complete control.

"Compare the eagle, slow down a little."

After thinking about the key to this, Mu Yang began to ask Bidiao to slow down his speed, preparing to test the speed that Bidiao can really control completely.

"Beep~"

After hearing Mu Yang's voice, the speed of the eagle changed again.
