Scheming against the invisible second year /Revealing

As Sophia rushed towards where the invisible second year was, she swung her black long spike continuously while it would seem like she was casually swinging the black spike randomly she was actually cutting off the invisible strings connected to the energy crystals that the invisible second year was controlling, the more energy crystal she cut off the more energy crystals was absorbed to her black long spike.

At this moment she suddenly stopped advancing forward, and stared at the place where the invisible second year was, it was at this moment he notice something the energy crystals at his side had reduced to more than half, what's more, he was sure the missing energy crystals had been absorbed by Sophia to her black long spike, as he looked at her, he fell into a contemplation he was sure she had something in mind, but he had no idea what.
