Eagle is the world’s longest life expectancy of birds. It lives up to the age of 70. To live such a long life expectancy, at 40 years of age it must make a difficult but important decision.

When the Hawks live up to the age of 40, its claws start aging, unable to effectively seize the prey. Its wings have become very heavy because its feathers grow thick and strong and make it very difficult to fly.

There are only two options:die, or rebirth through a very painful update process of 150-day long training session

由于羽毛厚而壮，它们的翅膀变得非常笨重，难于飞翔。

眼前只有两条路：死亡，或者穿越一个痛苦的150天的磨砺，获得重生
