"Xiaohe and Xiaoyanzi, you should retreat farther away......"

As soon as the demon dragon moved, the air fluctuated, and the stone tables and stone benches in the courtyard couldn't bear it and exploded directly.

Seeing this, Yue Qiubai hurriedly reminded Yan and Bai to retreat, while he himself held the Mingyue Holy Sword tightly with both hands, ready to make a big move.

In fact, there is no need for Yue Qiubai to remind them, although Yan and Bai have progressed, their current cultivation is still weaker after all, and when they encounter the existence of the demon king level, they are not able to fight at all, and the two are not sluggish, as soon as they saw that the arrogance of the demon dragon was so fierce, they instinctively retreated on their own, and resorted to the supreme body method, and directly climbed over the wall and crossed this small courtyard, avoiding it from a distance, so as not to suffer from the fish in the pond.

"Kill"

Of course, Yue Qiubai would not sit still, he roared fiercely, and he was about to make a move to slay the dragon.

But at this moment, a voice suddenly grew in the sea of knowledge: "Boy, this demon dragon is too fierce, it is definitely not what you are fighting against, so don't go up and die in vain, let Bendi help you solve it......"

It was the voice of Ming Lao, full of an invincible and firm belief.

Yue Qiubai was overjoyed when he heard this, and responded: "It's okay! ”

Shout!

I saw that the Mingyue Holy Knife flew out suddenly, like a faint blue extreme light rushing to the jaw of the demon dragon.

Phew!

The demon dragon raised a huge claw and struck out, wanting to slap the Mingyue Holy Knife away, but the Mingyue Holy Knife was very agile and dexterous, and the flight trajectory suddenly deviated, and it flew over with the dragon's claws, leaving a deep wound, and there was no bloodshed, only a black gas came out.

"Roar"

The demon dragon was injured, roared angrily, and abandoned Yue Qiubai and pursued towards the Mingyue Holy Sword.

When the moon is in the sky, the corpse king is born!

I saw the Mingyue Holy Sword hovering in the void, evolving into a vortex, and with a flash of red light, the Blood Corpse King appeared.

After devouring the essence and blood of the Golden Crow King and the Blue Bird King successively, now, Ming Lao's body has become more powerful, with an abyss-like aura and a domineering spirit.

Then, the two sides fought in the air.

How spectacular is the duel between kings?

In a matter of moments, a good courtyard was reduced to a pile of ruins, desolate and desolate.

Phew!

Phew!

Phew!

After all, Jiang is still old and spicy, as an emperor who has lived for an unknown number of spring and autumn periods, how can Ming Lao's methods be comparable to the demon dragon in the first realm of a demon king?

The Ming Moon Holy Knife was in Ming Lao's hand, it simply became extremely mysterious, and the divine power was endless, and between the changes, it shredded the void and left countless wounds on the demon dragon's body, full of holes.

Eventually, the dragon leaked everywhere, and grew smaller like a deflated ball.

"Roar"

The demon dragon roared unwillingly, and then, I don't know what secret trick it cast, and its tail spun up.

In a short time, it evolved into a small black sword, the size of a finger.

"If you return to a sword, see you in Jiuquan!"

A grand voice was conveyed from the small black sword, pointing directly at the hearts of people.

Then, with a bang, the small black sword turned into a bolt of lightning and flew towards Ming Lao.

"This sword...... Seems like a big deal...... I wonder if Ming Lao can stop it?"

Yue Qiubai felt it, that little black sword contained a world-destroying energy, which made people's hearts palpitate and uneasy.

Seeing this, Ming Lao smiled coldly, and suddenly, as soon as his body moved, he turned into a ray of light and drilled into the Ming Moon Holy Knife.

Then, the Mingyue Holy Knife swirled in the air, transforming into a vortex.

The next moment, the small black sword happened to fly, and in a flash, it disappeared into the vortex.

Then, the Singing Moon Sacred Knife stopped, and hovered there silently.

"That's the end of it?"

When Yue Qiubai thought that everything was over, all of a sudden, the suspended Mingyue Holy Sword burst out with a strong light, and it actually ignited a layer of bright red flames, rendering the original blue blade into a bright purple color, which was very dazzling.

"What's going on?"

"Could it be that the little black sword exploded after being absorbed into the inner space of the Mingyue Holy Knife?"

Yue Qiubai was a little surprised, wondering if this situation was good or bad?

"Boy, do you have a half-saint soldier on your body?" At this time, Ming Lao's voice suddenly sounded in Yue Qiubai's sea of knowledge, and there was some eagerness.

Yue Qiubai was stunned for a moment, and hurriedly responded: "Yes, there is a Blood Heaven Blade obtained from the Blood Witch Temple, which is a half-saint soldier-level ......."

Elder Naru: "Quick! give it to me......"

"Good!"

Yue Qiubai didn't ask Ming Lao what he was going to do, he directly took out the Blood Sky Blade, and then threw it at the Ming Moon Holy Knife in the air.

As soon as the Blood Sky Blade approached the Moonlight Saint Soldier, it was sucked in by the latter.

Then, as if adding fuel to the fire, the Mingyue Holy Sword became even brighter and brighter.

It lasted for a full quarter of an hour, and only then did the brilliance on the Mingyue Holy Sword fade.

And the Mingyue Holy Sword had already transformed into a bright purple color, and it looked even more powerful and sharp.

"It's ...... The Mingyue Holy Knife seems to have advanced?" Yue Qiubai only felt that the Mingyue Holy Knife had become more mysterious and sharp, and he measured whether it had advanced to a mid-grade holy soldier?

However, Yue Qiubai hadn't seen what a mid-grade holy soldier looked like, so he wasn't sure if this Mingyue Holy Sword had advanced.

Shout!

The Mingyue Holy Sword was silently suspended for a while, and suddenly it suddenly moved, and it turned into a streamer of light and submerged into Yue Qiubai's eyebrows, and disguised itself as a white mark.

"Hmm, I feel that the Moonlight Holy Sword has become more powerful now......" Yue Qiubai thought in his heart.

After thinking about it, Yue Qiubai communicated with Ming Lao with his thoughts: "Ming Lao, what is the situation now, has the demon dragon been completely killed by you?"

After a while, Ming Lao responded: "Yes, this dragon has completely died, but it is a good dragon that sacrifices itself for others, and it should not be called a demon dragon, which is not appropriate?"

Yue Qiubai: "Sacrifice yourself for others?" Ming Lao, what is the situation?"

Ming Lao: "The current situation is that I used the energy of the Demon Dragon's self-detonation, and also caused the Blood Sky Blade to self-detonate, and then used the energy of the two to successfully repair part of the inner space of the Mingyue Holy Knife, and promoted to the first order in one fell swoop...... Now, the Mingyue Holy Sword has regained the demeanor of a mid-grade holy soldier and has become sharper. ”

Yue Qiubai: "Have you really transformed into a middle-grade saint soldier? It's too mighty......

Ming Lao: "Yes! The Ming Moon Holy Sword has evolved one level, and if you use it in the future, your combat power can be increased by at least three percent." ”

Yue Qiubai: "Sancheng, then, wouldn't I be fearless when I encounter the power of the low-level Moon Sect in the future?"

Ming Lao: "Well...... It shouldn't be a problem to deal with the first- and second-order Moon Sects......"
