The remaining twenty or so officers also took action at the same time.
Mu Bai's body suddenly erupted with strong murderous intent, and he directly entered the dual forms of Dark Demon Transformation and Shura, and his figure rushed forward as fast as lightning.
"Whoa!"
A three-foot-long pale green sword light shone from the cold sword edge, cutting through the air and piercing the chest of an officer at a tricky angle.
When Driss was about to launch a spell attack, Mu Bai's figure suddenly came to his ears and said: "Go further away."
Driss was startled. Although he didn't know what Mu Bai was going to do, he didn't have time to think about it. Mu Bai had already blocked the officers in front of him, and he instantly flew into the air.
The moment he left the ground, the mighty dark demon power burst out of Mu Bai's body, forming a terrifying spiral airflow.
"Ah! Run!"
"No--"
None of the surrounding officers expected that Mu Bai would suddenly burst out with such astonishing dark demon power, and they were immediately sucked into the spiral airflow.
"What kind of skill is this?" Driss, who was in the air, saw the terrifying spiral airflow below and broke into a cold sweat. If he had been a step too late, he might have been sucked into it.
Mu Bai directly used the Nine Transformations of Reincarnation, and none of the officers could escape.
When the speed of the spiral airflow increased to the point where it was about to shatter the space, the officers inside were unable to withstand the terrifying strangulation force, and their bodies were torn into pieces one after another.
After killing these officers, Mu Bai's figure immediately rushed to Driss' side.
Driss exclaimed: "This is the first time I have seen a monster like you, and you are actually Shura!"
Mu Bai had been deliberately hiding his aura before. Although the murderous aura in his body was still very strong, Driss was still not sure that Mu Bai was Shura.
Mu Bai said coldly: "I can't stay here any longer. Let's go."
Driss nodded and followed Mubai to fly towards the outside of the city at full speed.
Just when they were about to fly over the city gate, thousands of undead guards were already intercepting them in front.
Mu Bai sneered disdainfully: "Leave it all to me."
After saying that, a red light flashed out from his right hand, and the Dragon-Slaying Sword was summoned.
Using both swords and swords, he was seen killing the group of undead warriors like a whirlwind.
These undead warriors are generally demigods in strength. With this level of strength, they can't even withstand Mu Bai's half-move attack.
The swords in Mu Bai's hands were flying, and every sword contained extreme killing power. These undead warriors were like straw, being ruthlessly harvested by Mu Bai.
