"Are you okay?" Juverin asked Samael.
Samael knelt on the ground, nodded, trying to catch his breath. The aura barrier he had formed was still stable and strong. But Juverin, who formed two barriers at once, began to sweat.
Actually, a dragon can experience a period of growth alone. However, in the first stage of growth, a dragon will lose control because he has no experience in the growth period. Thus, Orcen, the Dragon Emperor, was able to experience his second and third growth period alone, even though he had to seclude himself for quite a long time. And him, able to do it alone, made him one of the bravest and astonishing dragons out there.
Traditionally, dragon parents will oversee the first growth of their children. The dragon's first growth period is very violent and full of explosions of dragon aura. If needed, the dragon parents would put up an aura barrier to withstand the explosions.
