After Princess Zhang Le had formed her avatar of the God of Thunder, she was able to command all the lightning in the world as effortlessly as if they were her arms. With just a thought, she could make bolts of lightning rain. And compared to those immortals, who had to perform incantation gestures and recite spells to unleash such powerful lightning attacks, both her speed and the power of her lightning were much faster and stronger.
But, she did not put in too much of her energy into this attack. After all, she was much stronger than her foes; if she killed these thousand-odd Oracles with a single strike, she might attract some unwanted attention, which Wu Qi was trying best to avoid. Therefore, she had only used a little bit of her energy, making the power of the lighting about the same as the strongest attack unleashed by someone who had just stepped into the realm of Supreme Oracle.
