Aldrian was astonished inside, as this was truly not a trivial matter. The fact that Zhu Yanling could even absorb some amount of energy near Feng Xuanyan's blood showed that there was something special about her that no other phoenix possessed in the egg phase.
For phoenixes, the time they spend in the egg phase varies, but normally it takes more than two years before they hatch. The environment of the egg also affects its development, as it will greatly influence them in the future after they hatch.
The eggs keep absorbing energy from the surroundings to nurture the phoenix's embryo inside. The richer the surroundings are with heaven and earth energy, the more likely they are to become strong phoenixes. Likewise, the poorer the environment, the more likely they are to become weak phoenixes.
