The Hellhound didn't stop his attack, and sped towards them. This time, it may want to take their lives directly, leaving no room for a blow.

Chu Muyu faced an attack that was more powerful than just now, and this time he didn't retreat half a step at all, his real body blocked in front of Xiao Ran, and his right hand was raised unconsciously to protect himself.

"Xiao Ran, let me protect you this time......" Chu Muyu didn't look back, his whole body strength was raised to the highest, and the color of his eyes became dark yellow.

The hellhound claw slapped directly towards the top of Chu Muyu's head and slapped on his raised right hand.

In an instant, a golden light appeared, and the relics on Chu Muyu's right index finger emitted a strong golden light that was different from usual.

The claw was blocked by a cyan sword that lay in mid-air, and a burly man about the size of the Hellhound stood in front of them, this man was fully armored, his body was half empty and half solid, and the Aomine Sword in his hand emitted a long blue light.

Chu Muyu was a little stunned by the scene in front of him.

"It's ...... Guarding the true body?Xiao Ran couldn't believe what he saw in front of him.

Growth Heavenly King, Chu Muyu never thought that this was his father's guardian true body during his lifetime. Looking at another behemoth that suddenly appeared, he was a little overwhelmed.

"Brother Mu Yu, you are practicing the Yunding Exercises, why can you summon the guardian true body of the Sanskrit Yin Exercises?"

Listening to Xiao Ran's question, he looked at the relic on the ring. Thinking of the day of apprenticeship, the master said that this is the treasure of the Buddhist sect. "Are you protecting me? What kind of relationship do you have with me?"

Suddenly, small thorns grew around the nine barbs on the back of the Hellhound, and shot at them. The Growth King spun his sword with both hands and flicked all the thorns out.

Hellhound has smoke coming out of its mouth, and a large cloud of magma erupts from its mouth. The Growth Heavenly King wielded his sword, and several sword qi slashed through the magma, and the magma was split and flew in several directions, easily defusing the attack of the hellhound.

He jumped into the air and stabbed his sword at the Hound on the ground, and the sword split into several in the air. The Hellhound leaped behind him to dodge the attack, his sword stuck in the ground.

"This ...... What kind of battle is this?" Chu Muyu said in horror.

"Brother Mu Yu, let's hurry up and find a safe place, we can't stay here, their battle may affect us at any time. ”

"Hmm...... Good. Chu Muyu hurriedly picked up Xiao Ran, ran behind him, and hid behind a stone in the distance.

The Hellhound turned red all over, and its body looked like it was made of magma, emitting thick smoke, and it looked like a giant flying fox that had just been burned.

He flew down from the sky and lifted the sword stuck in the ground, and slashed through the whole sword through the body of the hellhound and slashed at the ground. The Hellhound is now like a liquid fused with it, and can pass through its body no matter how it attacks, and it can't do any damage at all.

The Hellhound ran over quickly, and the Heavenly King took advantage of the sword, and both the human and the sword passed through its body. The Hellhound appeared behind the Growth King, and a mouthful of magma spewed heavily into the back of the Growth King.

"I have a way to deal with it, Brother Mu Yu!"

"What's the way?" Chu Muyu asked as he looked at Xiao Ran.

"It's like magma all over it, and if there's an attack from the water system, I think it should be able to deal with it. After saying that, Xiao Ran had an icicle hanging from the palm of his hand and threw it towards the hellhound. When the icicle was about to approach the Hellhound, it turned into water due to the high temperature, and the water hit its body with a "bang", and a puff of black smoke turned black where it was hit by the water.

The Hellhound sbarked and looked back in Xiao Ran's direction, and the Heavenly King swung his sword, and a sword aura flew towards it, attracting the attention of the Hellhound again, and the sword qi passed through the Hellhound and knocked down a big tree behind it.

At this time, there were countless icicles floating around Xiao Ran's body, her eyes turned purple, and she used all her strength to push all the icicles towards the hellhound, Xiao Ran collapsed to the ground, the injury just now and the forced use of the exercise now caused her to be extremely weak.

The dense icicles all turned into water behind the Hellhounds, like a giant wave hitting them. A thick cloud of black smoke rose into the air, and in the smoke, the hellhound's body was scarred and covered in blood, and it was also relieved of its magmatic state, and fell to the ground. The Growth King jumped to his feet, grasped the handle of his sword with both hands, and stabbed the head of the Hellhound. It didn't have any struggle, and the 10,000-year-old demon beast died at their hands like this.

Chu Muyu helped Xiao Ran and walked over, and the Growth Heavenly King also turned into golden light at this time and was absorbed by the relics in his hands.

"Are you alright, Xiao Ran?"

"I'm fine, this hellhound is a 10,000-year-old demon beast, it's very lucky to be able to save my life, this injury is not a big deal, I will absorb the soul of this demon beast in a while, and the injury will naturally heal." Xiao Ran sat down next to the corpse of the hellhound.

"Soul absorption?" Chu Muyu hadn't heard anything from Senior Brother and Master about the Soul Devouring Technique, so he didn't know anything.

"Well, if you don't break through the sixth layer of the soul devouring technique, absorbing the soul of the demon beast can only improve your own strength, and it can also help me heal quickly, but I can't absorb it and become a guardian demon beast. This demon beast is not something that everyone can beat, even if you break through the sixth layer of exercises, it is very difficult to successfully kill the 10,000-year-old demon beast. ”

Xiao Ran began to absorb the soul of the hellhound, while Chu Muyu sat next to him and quietly looked at the ring in his hand, who did Xiao Ran say about the guardian true body belong to from the ring? Chu Muyu didn't think much about it, and began to use his aura to heal himself.

After about two hours, Xiao Ran successfully absorbed the soul of the hellhound, and also improved from the 'soul killing' to the 'Demon Pupil' realm, and the color of his eyes changed from purple to orange.

"Brother Mu Yu, I'm fine, and my injuries are healed. Xiao Ran got up and stood up.

"Uh...... Your eyes have changed color!Have you broken through a layer of realm?" Mu Yu said in surprise.

"Yes, Brother Mu Yu, thanks to you, I have the opportunity to break through the second layer of exercises so easily, otherwise I don't know how long and what month I want to practice. ”

"Hehe, when I was healing my martial arts just now, I found that my Yunding Technique was about to break through the second layer, and these successive battles have improved my aura a lot. But if you want to break through the second layer, you still have to go back to the Spirit Gathering Pool of Yunding Peak to absorb the aura."

"Congratulations, Brother Mu Yu!"

"Well, when I find the seven-colored grass, I will return to Yunding Peak to break through the second layer of exercises. ”

"Then let's go, hurry up and find the seven-colored grass. Xiao Ran wanted to help Chu Muyu find the seven-colored grass as soon as possible, but after finding it, he wanted to return to Yunding Peak, and Xiao Ran was a little reluctant.

Chu Muyu and Xiao Ran continued to walk towards the depths of the cave, and after walking for a long time, at the end of the cave was a meadow, and there was no cave roof rock above the meadow, which could directly lead to the ground. A ray of sunlight shone down from above, and in the middle of the meadow grew a green plant about half a meter high, which emitted a green mist all over its body.

"Brother Mu Yu, that should be the seven-colored grass, right?"
