The spirit’s lightning didn't intimidate Melkith, but it was an indication of an impending burst. Still, Melkith didn’t scream despite the fact that she got entangled in the explosion.

However, she was shocked. She knew how this explosion had occurred. The World Tree’s spirits, who were wandering about, had entered through the barrier’s cracks and turned into lightning. Due to the sudden increase in energy, the lightning flame had burst, unable to withstand the power.

‘…Is this even possible?’ Melkith wondered.

Recovering her posture ruined by the explosion, Melkith brushed the electricity off of her as if she was brushing off dust.

[It’s impossible.]

It wasn’t Levin who answered. It was Yhanos, the silent Earth Spirit King. It was really rare for him to speak, but he answered Melkith this time.

[Spirits can’t change their nature.] 

Primal spirits existed in the wind, fire, earth, and so on. They didn’t have an ego; they were just another form of mana. However, primal spirits couldn’t really be used as mana. Primal spirits of earth were, in the end just earth spirits.

Melkith was also well aware of it. The basics of spirit summoning magic was to understand the nature of spirits. Even though they couldn’t be seen by ordinary people, they surely existed. A wind spirit could never become an earth spirit. An earth spirit could never become a flame spirit. A flame spirit could never become a water spirit…

She turned back with a stiff expression. The young World Trees didn’t have a single scratch, despite the sudden explosion. She could sense the World Tree’s spirits dancing around the branches.

Trees also held spirits. However, spirit summoners didn’t really like them, because tree spirits had too many restrictions compared to other spirits. If the summoner called upon them in a forest, tree spirits were undeniably strong, but when they weren’t in a place with trees, they weren’t all that useful.

Even the World Tree was nothing else but a giant tree in the end. However…those spirits were quite different from tree spirits.

Melkith dryly laughed and looked forward.

Eugene was sitting still, just like before, but the lightning flame was no longer visible in his hand. Instead, the lightning had blended...
