[Crossover] The Most Evil Witch

The Aos Magic Plane is a world where magical civilization has flourished to an extraordinary degree. Every mage here makes touching the Source their lifelong goal and belief.

As a transmigrator, Tia was already standing at the finish line the moment she entered this world. Before she was even born, she had touched the Source.

But this was no blessing. After touching the Source, she was infected by its poison. Once she gained some ability to act, she became unable to tear herself away from the pursuit of every kind of knowledge, losing almost all independent thought and becoming a machine that endlessly investigated the world's origins.

Fortunately, her soul from another world left her some room to struggle. After directly shattering most of the Magic Plane in one fell swoop, she finally broke through the barrier between dimensions, escaped the Source's poison, and gained true freedom.

The surviving inhabitants of the Aos Magic Plane called Tia, who had committed this extremely evil and insane deed, the Wicked Witch.
