However, how could Mu Yu go as they wished.
With a big movement, his body flashed directly above the head of the Evil Spirit King.
The sword force naturally struck down towards the head of the Evil Spirit King.
In desperation, the Evil Spirit King crossed his palms, and violent power spurted out, blocking the top of his head.
"Bang!"
The fierce sword force struck the Evil Spirit King's palms without any reservation.
In an instant, the Evil Spirit King fell down at the speed of a meteorite and crashed onto the ground.
A huge deep pit was created, and the surrounding ground cracked like a spider web.
After the smoke and dust in the sky cleared, an extremely miserable figure was revealed.
The Evil Spirit King's entire body was covered in blood and flesh, and his two fleshy palms were sliced off by Mu Yu's sword.
Seeing this scene, everyone in the Cultivation Alliance's eyes lit up, and excitement could not be concealed on their faces.
The three kings of the undead clan, who were generally invincible, were so vulnerable in Mu Yu's hands.
Shangguan Yue'er also opened her beautiful eyes wide and murmured: "I didn't expect that only half a year later, he has already surpassed me."
Naturally, Mu Yu would not give up such a good opportunity.
As the saying goes, if you are sick, I will kill you!
At this time, it is natural to pursue the victory.
"The dawn breaks!"
Mu Yu raised the Sky Splitting Sword high, and the sky suddenly became dark.
Everything is lonely, the light breaks!
A brilliant ray of light passed through the darkness, and endless life force gathered from all directions.
The power of life is like deadly poison to the undead tribe.
"Come and save me!"
The Evil Spirit King was trembling all over and roaring ferociously.
Chengfeng King and Blood Killer King looked at each other, and then Blood Killer King took out a black gourd and placed it above his head.
Extremely weird black smoke spewed out from the gourd, transforming into a huge dark beast.
The giant beast's body exudes the deathly aura of the Nine Nether Hells.
Its body arrived at the side of the Evil Spirit King in an instant, and a huge palm tens of feet raised up into the sky, and suddenly swatted out towards Mu Yu.
Mu Yu's sword completely struck its palm.
But only a shallow scar was made, and the life force completely dissipated.
Mu Yu raised his eyebrows. The strength of this dark giant beast was too terrifying. It was several times stronger than any opponent he had encountered before.
As he watched, that huge palm was about to swallow his body.
Mu Yu immediately used Great Teleportation to retreat dozens of feet away and returned to Shangguan Yue'er's side.
Withdrawing the red star stone, the violent power dissipated within his body.
At the same time, he took out the yellow star stone and integrated it into the earth's surface with a flick of his finger.
With a loud rumbling sound, the mountain giant burst out of the ground, sweeping away countless undead tribesmen around it.
Under the control of the Blood Killing King, the dark black giant beast rushed towards the city wall and fought with the mountain giant.
"Senior Sister Yue'er, let's return to the city first."
Mu Yu said, as long as the dark giant beast is there, they will not be able to break out of this place for the time being.
When returning to the city, you can use the formations arranged on the outside of the city wall to temporarily delay them.
Shangguan Yue'er knew the critical situation and without any hesitation, immediately issued an order: "Everyone, please return to the city."
Under the cover of the mountain giant and Mu Yu, everyone returned to the city.
The nine formations on the outside of the city wall were opened directly, and for a while, the undead army could not attack.
The remaining effective forces of the major forces all gathered together to discuss other ways to help them break out.
