"We can only do this." Tu Xingyun seemed to have finally made up his mind. "You and I will each hold one of the Yin-Yang Purifying Thunder Bottles. The thunderforce within this formation is clearly more strange and ferocious than before. A single Purifying Thunder Bottle simply can't open the formation again. I know you still have another Cloud Slave you haven't used. Bring it out."
Tu Xingyun raised a palm, and a white bottle about a foot tall, burning within like a blazing sun, flew toward the silver-robed old man. "Junior Brother Zhou, I'll trouble you to break the formation together with Fairy Yunxia's Cloud Slave."
"Yes, Senior Brother Tu." The silver-robed old man accepted the Purifying Thunder Yang Bottle without changing his expression.
Fairy Yunxia pointed with both sleeves. Amid the spreading clouds and rosy glow, the clouds gathered and roared, gradually forming the rough shape of a human body. It was none other than the other Cloud Slave Tu Xingyun had mentioned. The black Purifying Thunder Yin Bottle held in the Cloud Slave's palm had an aura that perfectly complemented the Purifying Thunder Yang Bottle in the silver-robed old man's hand.
"Cackle, cackle. Don't you want the Thunderlight Battle Armor? You'll achieve your goal as long as you put in a little more effort. Why are you in such a hurry to leave?" The red-faced, fanged thunder demon shrieked with laughter. Its curved blade repeatedly slashed through the void, sending out crescent moons of saber qi. Within those crescent-shaped blades of qi were what seemed like tiny thunder domains.
Tu Xingyun and Fairy Yunxia exchanged a glance, both detecting something strange about the thunder demon. It seemed drastically different from before. Their resolve to leave quickly grew even firmer.
Whoosh, whoosh, whoosh... The red-faced, fanged thunder demon
