The four of them understood, and the Holy Spirit General had already entered the subterranean space.

Chu Nan stretched out a finger to his lips and made a silent motion at An Yi and Bu Feiyan, and then winked at them.

An Yi and Bu Feiyan were stunned, glanced at each other, and nodded to him.

Chu Nan pulled up the sleeves of his two hands, and wrote two lines of words on each of them.

An Yi and Bu Feiyan looked at each other, showed surprise, hesitated, and nodded at him.

At this time, in the underground space, the dragon in that formation had already opened its eyes, but there was no life in those huge eyes, only the fierce aura from the ancients, and its huge body was vibrating rhythmically, like the waves of the sea undulating.

The Death Demon Venerable was suspended in mid-air, the black robe on his body had turned into powder, showing the huge black skeleton, and between his chest and abdomen, there was also the same light as the purple light flashing in his pupils, as if a heart was beating when he put it away.

The Death Venerable's huge bone sword stabbed diagonally into the ground, he spread out his hands, and the sound of a spell like thunder in his mouth was in his mouth, and from the dense texture of the bone sword, there was a thick stream of death qi rushing out, entrenched in the palm of his outstretched hand.

The entire space is like a nine-layer purgatory.

Around this formation, the few surviving king-level powerhouses were almost exhausted, and they would soon return to Bliss.

Suddenly, the Death Venerable put his hands together, and the two balls of dead qi completely fused, and in an instant, they turned into a ball of light and headed towards the huge head of the ancient dragon.

Then, the purple light that flickered in the Death Venerable's pupils suddenly separated and followed towards the black light.

A black and purple light sank into the ancient dragon's head, and in an instant, the ancient dragon's huge body trembled, and it suddenly raised its head high, and the light in its eyes flashed like purple lightning.

At this moment, the Holy Spirit General appeared, and as soon as she appeared, all of a sudden, black light poured out from all directions, forming a web around her, enveloping her.

The Holy Spirit General's eyes flickered, and he said to himself: "He is really cautious enough, this is obviously a restraint against me, it seems that he has never trusted me." ”

Immediately, the Holy Spirit General smiled strangely and said, "But I have already guessed it, how could I not be prepared." ”

Suddenly, the Holy Spirit General clasped his hands together, and a burst of blue light flashed in the center of his eyebrows.

On the edge of that formation, the eyebrows of several king-level powerhouses who had only their last breath left also flashed with blue light, and they who were still dying suddenly became fierce dragon spirits, they all got up together, and came to the huge head of the dragon, and the blue light in the center of the eyebrows shot into the dragon's head at the same time.

Suddenly, the purple lightning in the dragon's eyes was entwined with cyan light, and the dragon's huge body trembled, and its high head hung on the ground.

At the same time, the Death Venerable's body was trembling incessantly.

At the entrance, the spar in front of the four of Chu Nan suddenly lit up, and the four of them glanced at each other and rushed in like lightning.

When the four of them rushed in, at the four points inside, a light lit up at the same time.

The Holy Spirit General, who was shrouded in a black light net, couldn't help but smile excitedly when he saw the four people coming in, as long as the four of them stood on this light and urged the soul power, it was the dust that had settled.

However, the Holy Spirit General's smile quickly froze on his face, because the four of them did not stand in those four positions according to the plan, but walked towards the several king-level powerhouses controlled by her on the side of the dragon's head.

Chu Nan caught Mai Duxiu, and Xie Lingyan picked up Granny He.

"How can you dare to betray me?" General Spirit did not speak, but the voice of anger echoed in the space.

Chu Nan and Xie Lingyan ignored her, but Mai Duxiu and Granny He were controlled by the Holy Spirit General, and they couldn't move.

"You will not succeed, and you will save them unless you can cut off my soul from them. The murderous voice of the Holy Spirit General sounded again.

Chu Nan smiled, and suddenly, two silver flames appeared in his hands, directly hitting the eyebrows of Mai Duxiu and Granny He.

In an instant, the Holy Spirit General's face turned pale, and a look of pain flashed in his eyes.

"Let's go. Chu Nan let out a low shout, and the four of them began to retreat with the extremely weak Mai Duxiu and Granny He.

However, just as they were about to rush out, suddenly, a cloud of purple light separated from the pupils of the Death Demon Venerable, turning into a clone phantom and rushing towards them.

"Huh"

A ray of light and shadow slashed in, and the surging terrifying energy made everyone tremble.

Chu Nan made a judgment in an instant, he slammed Xie Lingyan and pushed her out of the attack range, while he snorted and flew up with blood spurting from his mouth.

While flying, Chu Nan threw Mai Duxiu to Bu Feiyan and hissed, "You go first, and I'll come later." ”

Chu Nan was bounced off the hard wall, and the pain made his handsome face distort, but he didn't pause, and rushed towards the phantom that the Death Demon Venerable had conjured up with one step.

Among the several people, he was the only one who was sealed with Xuanli but was threatened, his body was turned into a copper skin and iron drum due to the spiritual fire, and he still had spiritual fire to use as a means of attack.

"Let's go. Xie Lingyan glanced at Chu Nan and bit her lower lip, but she was the first to scream, she couldn't let Chu Nan's hard work go to waste.

The three of them rushed out with Mai Duxiu and Granny Crane and returned directly to the mine.

At this time, Chu Nan no longer kept it, and directly urged the silver humanoid spiritual fire, and even forced the phantom of the Death Demon Venerable not to approach, but whenever he wanted to leave, the phantom of the Death Demon Venerable dragged him back in various ways.

And whether it is the Death Demon Venerable or the Holy Spirit General, they all want to break Chu Nan's body into thousands of pieces, but it is impossible for the Death Demon Venerable to give up control of the ancient dragon, and the Holy Spirit General is impossible to give in, she has no way back, once the Death Demon Venerable really controls the ancient dragon, she will be the first to die.

After trying many times and failing to escape, Chu Nan simply didn't try, there was a silver flame burning in his hand, as long as he forced the clone of the Death Demon Venerable not to approach.

After that, the clone phantom of the Death Demon Venerable simply blocked the entrance and exit, and began to concentrate on fighting with the Holy Spirit General in the sea of consciousness of the ancient dragon.

Chu Nan didn't move, as if he had accepted his fate.

And at this time, on the formation at the end of the side of the Holy Spirit General's Mansion, Xie Lingyan, An Yi, Bu Feiyan, and Tianxiang from the dungeon were also here, Granny Crane and Mai Duxiu were sitting weakly on the ground, and the snake master who was tortured by the Spirit Fire Ant was also there.

On the energy shield of this formation, a hole suddenly appeared, and this hole could not only be passed by dead things, but also by living things.

"Let's go in first, the master said, this passage can only last for a quarter of an hour, and now this passage has been opened for more than half of the time, if you don't go in, isn't that master busy in vain?"

"Shut up. Xie Lingyan's cold gaze swept over, and there was a trace of blood in his plain and indifferent beautiful eyes.

"In this case, let's go in and wait for him at the edge of the formation. Bu Feiyan glanced at Xie Lingyan, although she was also anxious in her heart, but unlike Xie Lingyan, her performance was obviously a manifestation of the real emotion of the white-headed guy, it seemed that her emotions were on the verge of getting out of control, which was completely inconsistent with her character.

Xie Lingyan took two deep breaths, looked at Granny He and Mai Duxiu, and nodded.

The group got into the hole and stood at the edge of the formation.

Time passed minute by minute, but Chu Nan still did not appear.

In the underground space, Chu Nan, who had always seemed to have accepted his fate, suddenly burst into shape, and his speed was not slower than that of ordinary Xuan generals, and he rushed towards not the entrances and exits, but the ancient dragon.

When the doppelganger phantom of the Death Demon Venerable noticed it, it was too late to stop it, and the silver spiritual fire in Chu Nan's hand turned into a complete form in an instant, that is, a human form, and was slammed by him on the head of the ancient dragon.

The spiritual fire rushed in furiously, and the power of the silver spiritual fire in its full form was shocking, and it directly melted the purple and cyan entangled soul.

In an instant, the black soul of death returned to its place, and the ancient dragon roared, and its ferocity was completely aroused.

The huge dragon tail hung high, and the golden crystal light on it flashed with dazzling light, and it actually enveloped the Death Demon Venerable, the Holy Spirit General, and Chu Nan at the same time.

"Boom"

The ancient dragon swung its tail with a single move, and the Death Demon Venerable and the Holy Spirit General were swept away with a scream, and the entire underground space began to collapse.

However, Chu Nan disappeared at that moment, as if evaporated.

In the formation on the Holy Spirit General's Mansion, the light of the passage on the energy shield outside had become more and more dim, and it was about to disappear completely.

At this time, the entire space shook for a while, and the roar of the ancient dragon could be heard, the mine outside collapsed, and countless mine slaves were thrown away, and the Holy Spirit General's Mansion couldn't bear it, and pieces of rubble began to fall.

"No, we have to go. The snake lord screamed in surprise.

Xie Lingyan clenched her fists with both hands, clenched her silver teeth, and suddenly, she glanced at Granny He, who was sitting weakly with a complicated expression, and suddenly drilled out of the passage that was about to disappear.

"Xie Lingyan, what are you doing? Come in. Bu Feiyan exclaimed.

"I'm going to find Chu Nan, even if I die, I will die with him. Xie Lingyan said loudly, turning around and running out.

Chu Nan's mouth opened wide.

But at this moment, a shadow flashed like lightning, grabbed Xie Lingyan's waist, and **** entered through the disappearing passage.
