The main question to answer was: if that was a Lightning Spirit, how could it lie so quietly on the deck? It should have been trying to escape by then.
Lightning Spirits were living creatures and wouldn't passively wait for their demise.
Wang Teng was looking intently at the creature, which resembled a silver-white ball; semi-transparent in appearance, with occasional glimpses of purple within. Overall, it looked… round, flattened, and quite bouncy.
The odd fellow remained still on the deck, seemingly lifeless.
However, the hero used his Real Eye and noticed that the creature possessed life origin. It was very likely alive.
An absurd thought appeared in his mind, Is it playing dead?
He asked curiously, "Instructor, is this really a… Lightning Spirit?"
"It should be." The instructor touched his chin and pondered. "But, it should be a newborn, so its lightning power is weak."
