Suddenly, a peal of thunder rang out, along with a bolt of lightning. When this happened, Meng Hao’s eyes narrowed. He looked closely at the shield. After a moment, another bolt of lightning descended. Meng Hao’s eyes began to shine.
He had noticed that every time lightning struck, the shield would ripple.
“So, lightning bolts can affect it… If lightning strikes it, maybe the shield can be opened.” His heart began to thump. A huge group of metal flying swords appeared. He tossed them, hoping to be able to use them to attract some lightning bolts.
