Evan named his newfound technique as Soul detection technique. He was very much interested in this newfound ability. It could accurately locate a soul no matter how tiny or how weak the soul was. With this newfound technique, he could accurately target the soul of his enemies.
Even if a enemy managed to evade his physical attacks, he could still target the enemy with his soul attack.
He was already successful in his first soul attack. So, Evan tried to perfect his soul attack further. Previously, his attack destroyed the souls of some tiny ants,but Evan didn't want such wide impact. He was aiming for precision and accuracy in his attacks. Previously he molded his soul shard into a small spear.But now he was planning to create something more small which could directly pierce through soul of a single ant.
