The Instrument Spirit Green Dragon entangled the evil dragon, which gave Ning Xin a moment of respite and quickly flew towards the waterhole!

The two giant dragons soared in the air and fought fiercely, and the sound of the dragon's groan resounding in the sky was heard from the Wangkong Cliff far, far away!

The strength of the evil dragon is much stronger than that of the green dragon, and soon the green dragon was defeated, and the spirit body became weaker and weaker, but it still dragged the evil dragon with all its strength and did not let it pursue Ning Xin!

Coming to the waterhole, Ning Xin immediately ordered Qinglong to come back. It didn't take long for the dragon to chase the green dragon towards the waterhole.

The moment she saw the evil dragon, Ning Xin silently recited the lock spirit decision, and in less than a few breaths, a point of light flew out from the tip of her right finger, attacking the evil dragon like a meteor and submerging into its body!

The moment the point of light sank into the evil dragon's body, the evil dragon that was still attacking suddenly stopped, Ning Xin summoned back the green dragon, and sent out several divine soul slashes at the evil dragon one after another, and then jumped into the waterhole without looking back!

The strength of the evil dragon is too much higher than her, and the spirit locking technique can't stop it for a long time!

"Sister!" Seeing Ning Xin's pale face suddenly falling from the water curtain, the little black dragon was startled, and quickly came to her side to help her up.

"Master, are you alright?"

"I'm fine!" This time she was reckless, she wanted to take advantage of the fact that the evil dragon's soul power was weakened, and she took the opportunity to seriously injure it, but she didn't expect its strength to be so strong, it seems that urging a soul chasing stab can't weaken its soul power much!

Seeing that the white clothes on her chest were stained with blood, Ning Xin's eyes showed a look of joy, fortunately, the defense of this magic robe was good, otherwise the claw of the evil dragon would definitely be able to split her into several petals!

Then, after Ning Xin recovered from her injuries, she began to urge the Soul Chasing Thorn again, and after several times, she cautiously walked out of the waterhole and flew towards the cave of the evil dragon.

After entering the cave, Ning Xin was very cautious, last time it was because she accidentally injected her soul power into the Qinglong Fan, causing the dragon power in the fan to leak out, which made the evil dragon discover her existence!

The soul power was weakened several times, making the evil dragon very irritable, and the entire cave was destroyed by it! When Ning Xin entered, the evil dragon was lying on the boulder!

Seeing that the soul chasing thorn inserted in the evil dragon's soul body was slowly being forced out, Ning Xin's eyes sank, this evil dragon's soul power was above her, and it wouldn't be long before it could pull out all the soul chasing thorns she planted in its body!

However, after the fierce battle last time, and these few times to urge the soul chasing stab, Ning Xin could feel that the evil dragon's soul power was much weaker!

After thinking for a while, Ning Xin deliberately revealed her breath, and then immediately teleported in the direction of the waterhole!

Sure enough, after the evil dragon sensed Ning Xin's breath, he chased after her.

The powerful pressure of the evil dragon attacked, Ning Xin suppressed the violent aura in her body with all her strength, sacrificed the soul flute and began to play the requiem, and in an instant, the speed of the evil dragon slowed down, and it rolled in the air in pain.

At this time, Ning Xin breathed a sigh of relief, and while playing the Requiem, she flew towards the waterhole!

Along the way, the fierce attack of the evil dragon followed closely behind Ning Xin, and she was almost hit several times!

Coming to the edge of the waterhole, Ning Xin increased the output of soul power, which made the evil dragon even more crazy, attacking everywhere, but the main firepower was still against the waterhole!

In the deafening roar and powerful pressure of the evil dragon, Ning Xin gradually felt overwhelmed, her face became more and more pale, and just when she stopped playing the soul flute and was about to return to the waterhole, two figures, one green and one black, suddenly emerged from the waterhole and attacked the evil dragon!

When Ning Xin saw it, her expression turned grim, and she endured the discomfort of her body and used the spirit locking technique towards the evil dragon.

"Whew!" A fiery red flame erupted from the small black mouth, and the temperature of the entire cliff bottom rose suddenly, and when the flames flew to the dragon's body, its metallic black scales immediately dimmed!

On the other side, the little dragon that revealed its true body waved its claws and attacked straight towards the head of the evil dragon!

"Ahh

Xiaolong Xiaohei also knows that the evil dragon is powerful, and as soon as he succeeds, he will immediately return to the waterhole!

"Bang bang bang!" After Ning Xin's little dragon Xiao Hei submerged in the pool, the evil dragon that broke free from the soul lock technique launched a crazy attack towards the pool, stirring up waves of water!

At the bottom of the waterhole, after the aura and soul power were restored, Ning Xin looked at the unstopped attack above the water curtain, and looked at Xiaolong Xiaohei with an expressionless face!

"Do you two know that you are wrong?" Although they injured the evil dragon this time, if she didn't have the spiritual power to lock the evil dragon, I really don't know what the consequences would be!

Although the evil dragon was tortured by the Requiem and lost his mind, his strength was still there, and the two of them went out rashly, and if one didn't pay attention, he might die in the hands of the evil dragon!

"Sister, we just want to help you!"

"I know, but your current strength is not enough to fight against the evil dragon, if you are captured by it, I will not be able to save you!"

"Sister (master), we know that we are wrong, and we will never do this again in the future!" Xiaolong Xiaohei said weakly.

"The strength of that evil dragon is much higher than ours, so we have to be careful, and when the strength of that evil dragon is weakened to a certain extent, I will naturally ask you to help, but now is not the time!"

"We got it!"

In the days that followed, Ning Xin continued to urge the Soul Chasing Thorn, and when the last Soul Chasing Thorn in the evil dragon's body was pulled out by it, its soul power had already dropped to the point that it was not much different from Yunmo's!

The soul power has been weakened, the strength of the evil dragon has also weakened a lot, and the coercion exerted on Ning Xin and them is not as strong as before!

Ning Xin knew that the cultivation of the evil dragon was incomparable to her, so she could only find a way to slowly weaken the evil dragon's soul power!

After that, Ning Xin sneaked up on the evil dragon from time to time, and the Divine Soul Slash and the Imperial Soul Flute were used interchangeably, although they would be injured every time, but fortunately, the evil dragon's soul power was also weakened little by little!

When the evil dragon's cultivation descends to the upper immortal, it will not leave the cave easily, and it will be very difficult for Ning Xin to injure it in the cave without being injured!

At this time, Ning Xin let the little black dragon participate.

Every time you can't lure the evil dragon, either the little dragon enters the cave, or the little black breathes fire into the cave, no matter which one will lure the evil dragon out!

The temperature of Xiao Hei's fire is extremely high, which will make the whole cave seem to be bathed in a sea of fire, and the evil dragon can't stand it and will come out of it;

As for the little dragon, the evil dragon wants to swallow it into his stomach from beginning to end, and as soon as he appears, the evil dragon will chase after him desperately!

After that, Ning Xin and Xiaolong Xiaohei cooperated with each other, and they were able to hurt the evil dragon more or less every time!

Facing Ning Xin and Xiaolong Xiaohei, who fled into the waterhole without winning, the brutal evil dragon felt helpless, and every time it couldn't attack the waterhole, it would be more seriously injured!

One person and two demons are slowly consuming with the evil dragon, planning to grind this ancient evil dragon to death little by little!
