The excited youngsters rushed into the exit corridor. However, the shelter was a thousand meters underground. That was a long way to climb.
They didn't dare to take the elevators, fearing that they might be spotted.
However, they heard a rumbling noise as soon as they stepped into the corridor. The iron gate of the underground shelter was also supported by Innate Vigorous Energy.
The Innate Vigorous Energy not only covered the entire underground shelter but also supported all the escape corridors and three iron gates that led to the Pegasus Grassland.
The three gates blocked the natural disasters outside and were the second last defense of the underground shelter—the last one being the doors sealed by the Innate Vigorous Energy.
To enter the underground shelter, the natural elements needed to break down all three gates and the sealed door.
With the protection of the Innate Vigorous Energy, that was an impossible task.
