Chapter 237

In the fire, Chu Tian watched the big strange bird's shell slowly turn blue, and finally from head to foot, from the tip of head to the tip of tail, and even his claws turn blue.

"Boom!" A burst of raging flames came to his face, and Chu Tian took a breath of turbidity. The strength of this guy soared.

The strength of the big strange bird has always been only three or four levels. In this battlefield, the big strange bird has almost no role, because its strength is not strong. Fortunately, its hard shell can block the attack of weapons, otherwise the big strange bird would have been chopped into more than ten pieces.

But now, the power of the big strange bird is rising. Finally, it stopped at the level of level 6. Chu Tian grew up incredibly.

"NIMA, is that level six? My fast dragon is at the peak of level 6... "

No wonder Chutian is incredible. You know, the strength of the big strange bird itself is really slag. If it weren't for the three forces of shell, fire and flight, Chutian wouldn't necessarily call.

But facts have proved that the big strange bird now is not the big strange bird before. With the strength of level 6 primary level, the big strange bird has become a veritable green strange bird, and its combat effectiveness has soared so many times.

"Wow!" The green strange bird screamed. Chu Tian suddenly breathed out. He wanted to try the strength of the green strange bird. Looking around, he suddenly found several level 6 undead.

"Green strange birds, go, kill them and let me see your strength!"

The green strange bird glanced at the sky, suddenly screamed, waved its wings heavily, and its huge body suddenly flew up, flew out at an amazing speed, and fell heavily on the side of the group of undead.

"Wow!" The green strange bird gave a strange cry, and its slender tail, like a steel whip, shook it fiercely and heavily on a dead soul. The dead soul didn't even have the power to resist. The whole body seemed to have been cut by a laser and was cut off in an instant.

"Hiss!"

Chu Tian took a breath of air-conditioning. What a power it is. Unexpectedly, a tail cut the body of the dead in two. This is a tail flick, not the high-pressure water column of the water dragon over there.

"What a powerful force, what a sharp action!"

The green strange bird shook its tail again and patted off a dead soul. Looking at the dead soul rushing towards its chest, the green strange bird gave a strange cry, the huge wings beat fiercely, and the whole body suddenly soared into the air.

The huge wind pressure suddenly overthrew the dead in front, but the green strange bird jumped up, stepped heavily on the dead, and then took a breath.

"Boom!"

A fireball sprayed out from the mouth of the green strange bird, and the burning flame swallowed the body of the dead in an instant.

"What a powerful flame. It's almost the same as that of the male Fire Dragon..."

The flame of the male fire dragon comes from the volcano. Because the male fire dragon often eats volcanic rocks and other things, and the interior is rich in a large amount of phosphorus and carbon, the fireball is the hottest among all the summoned beasts of Chu sky so far.

However, the flame produced by the green strange bird is obviously close to that of the male fire dragon. Although it may not be comparable, it is at least close and much stronger than that of the female fire dragon.

"My God, a six level crystal nucleus has evolved a metamorphosis?" Chu Tian immediately looked at the crystal nucleus in his ring, and then looked at other summoning beasts. He didn't know if other summoning beasts would evolve if they ate them?

"Would you like one?" Chu Tian took out a six level fire crystal core and walked towards another big strange bird. Now the big strange bird dared not sleep. He looked at the green strange bird with doubt or shock on his face. Obviously, he was puzzled about the sudden change of the same kind.

"Eat or not?" Chu Tian handed over the crystal core in his hand, but the big strange bird seemed to see the poison, and actually went back several steps in a row. He looked at Chu Tian warily. Chu Tian scolded "shit", and suddenly his hand hurt. He saw that the level 6 fire crystal core was gone.

"Colorful bird?" Turning around, I saw the colored bird holding the six level fire crystal core. Looking at Chu Tian, he swallowed it with a gulp. Chu Tian was immediately excited.

The evolutionary type of colored bird, or a subspecies of colored bird, is called red colored bird. It is more powerful and grumpy than colored bird.

But Chu Tian was stunned. The red colored bird was different from the colored bird.

Cainiao, a creature, is also called "lighter", because there are two flints on the joints of Cainiao's forelimbs. This kind of flint will explode under strong touch, and this is the main attack means of Cainiao.

However, the stone in the hands of red colored birds, a subspecies of colored birds, is not flint, but tourmaline. What is produced is not flame explosion, but lightning explosion.

If the colored bird eats the crystal nucleus of fire system, will it be ok?

Chu Tian suddenly became nervous. The big strange bird and the green strange bird are strictly fire attributes, but the colored bird and the red colored bird, one is fire attribute, the other is thunder attribute, and the two are not one attribute.

Chu Tian sighed. It seems that colorful birds will not evolve.

Indeed, for the past ten minutes, the colorful bird still has no change, but it is burping, Chu sky turned a white eye, but fortunately, eat nothing good, the six crystal core Chu heaven still gave up.

However, when Chu Tian tried to take out the level 7 and level 8 Lei series crystal nucleus, Cainiao still ignored it. Chu Tian felt a headache. Was the evolution of green strange birds really just an accident?

If it's really an accident, it's too much. It can evolve from level 4 to level 6. This span is too shocking for Chu Tian.

"It seems that there will be a new research scheme in the future, that is, the evolution of summoning animals..."

Opening the interface, sure enough, a dark shadow broke inside. The green strange bird icon appeared on it, and there was an introduction behind it.

Green strange bird, evolution condition: Level 6 Fire System crystal nucleus, mental strength 20000 points.

"Eh?" Chu Tian was stunned. He opened his mental strength and compared it. He was surprised to find that his mental strength seemed to have no change.

In other words, the evolution of green strange birds only consumed a level 6 Fire System crystal core, and did not extract the 20000 mental strength of Chu Tian.

"Good thing, at least if I can save, I have to keep calling more powerful summoning beasts..."

Chutian smiled and watched the green strange bird easily destroy several level 6 undead. Chutian breathed out, but the law of evolution can't be touched. Since you can't touch it, forget it.

Let his summoning beast fight again. Chu Tian returned to the wall and told Leo about it. Leo was surprised. This guy couldn't keep up with Chu Tian, so he didn't catch up.

In a twinkling of an eye, another three days passed.
