Sneaky Gain

Abel turned to the walls in the hall. They were filled with cracks. It was almost like the entire submarine was going to break down with one more blow.

He would not use his power of the will without any protection, so he could only examine the damage with his eyes.

What he worried about the most was the submarine spirit. There was no way of connecting with it without using his power of the will.

Abel's heart began to race. Then, when he was about to abandon the submarine, he saw glowing white sparkles of energy begin to run through the walls. 

"Can this ancient submarine regenerate itself?" Abel thought.

Since the battle forts could so, this ancient submarine should be able to as well.

The recovery was quick. Maybe it was the special attribute of ancient materials.

Repairing was easy as long as they had enough energy, but of course, that was only if the spirit was not damaged.
