"Boom!"
At the instant collision of the stone spear and the basketball-sized molten fireball, an explosion occurred immediately.
This wasn't an ordinary fireball, it was a fireball that Wang Zijia had sealed in a book using the sealing technique.
For effectiveness, Wang Zijia had infused it to the limit. Although it wasn't as strong as an attack from the Fu treasure comparable to the Infant God, each spell in the book was almost the limit of Wang Zijia's current battle strength!
The massive close-range explosion immediately blew Wang Zijia, who hadn't retreated far enough, away. The energy shield on his body rapidly crystallized, but luckily it held up in the end and didn't break.
He tumbled several times in mid-air during his flight, and after half-kneeling down, he plowed a long track on the ground.
