"What, what is happening?" Quan Yi asked in surprise. Just then, a thick vine suddenly shot forward, coiling towards Quan Yi. The whooshing sound of the vine startled him and he subconsciously stepped back, tripping over the doorstep behind him and almost fell. His four guards instantly formed a shield in front of him. Blue, red, green, and yellow forces flared out, shredding the attacking vine immediately. However, the plants didn't cease their assault. Drawn to the scent of live humans, they continued their onslaught on the palace gate. Quan Yi's guards displayed tremendous power. Each of them drew their weapons and under the effect of their fierce aura, none of the plants could move past the line they drew. The plants were obliterated from their onslaught.
