"Huh? This... how is this possible?" The iron-winged black dragon exclaimed, and it suddenly felt that Mu Bai's aura surged several times in an instant.
"Ah!" Mu Bai couldn't help but let out an extremely painful cry.
How can words describe the pain of twenty-eight arrows piercing into the body.
The reason why he did this was to change the direction of the fighting spirit power in the energy veins, reverse the direction of movement, and run it counterclockwise, so that the power could rise to a higher level in a very short period of time. But by doing this
The damage to the body is huge. If the meridians cannot withstand the powerful force of the twisting, there is a danger of bursting at any time.
At this time, every nerve in Mu Bai's body felt like it was being burned by flames, causing extreme pain.
"Drink!" Mubai shouted, and the light shining on the dragon-slaying knife instantly turned into a deep purple color.
"Emperor-level fighting spirit power! He...how did he do it?" Ruian felt extremely shocked after feeling Mu Bai's power surge.
"Oh my God! What on earth did he do? How could it be like this?" Jian Wuhui was shocked after witnessing the changes in Mu Bai. Mu Bai shocked him too much.
"Whoa!" Mu Bai waved his dragon-slaying knife with his arm and slashed towards the iron-winged black dragon's chest.
The sharp knife struck in mid-air, creating a twisted crack in the space, which shows how powerful the knife was.
The iron-winged black dragon had to concentrate on dealing with it. It finally felt the pressure coming from Mu Bai.
"Roar!" The iron-winged black dragon spit out a stream of black smoke from its mouth, condensing into a smoke screen in front of it.
"Boom!"
A knife struck the smoke screen. With Mu Bai's body as the center, huge impact airflow rolled up all around, and the boulders on the ground were swept up one after another...
"Ouch!"
The iron-winged black dragon roared with difficulty, and its huge body was knocked back dozens of meters by Mu Bai's arrogant force.
"Druid of the Raptor! Get everyone out of here immediately!" Mubai took advantage of the last trace of his consciousness to shout to the Druid of the Raptor who appeared in mid-air.
The Druid of the Bird of Prey was obviously seriously injured in the battle with the Hell Snake King just now. There were several very deep wounds on his body and he was burned to a crisp.
