The black spear came very suddenly, like a bolt of lightning.

After inserting it into the ground, a stream of black gas gushed out from the black spear, enveloping the old man, and after a while, the black gas forcibly pulled out the black mist monsters that were about to erode the old man's body, fighting with each other, but obviously, they couldn't help each other for the time being.

But at least, the old man was saved.

"Who!"

The Demon Lord's clone was furious, and when he saw that he was about to succeed, he was actually stabbed sideways by someone, and he fell short, so he was naturally extremely angry. At the same time, a man flew in the distance and landed beside the old man.

The person who came was naturally Xu You.

He came all the way, using his doppelganger's imperial art, and what he controlled was his own body, Xu You's doppelganger's imperial art had already reached its peak, after all, he only practiced one technique, and under the study, the realm reached was unparalleled, and the subtlety of the imperial object was unimaginable to ordinary people.

Therefore, even if he has no cultivation in his body, he can fly, and his speed and agility are more powerful than any other monk.

After landing, Xu You glanced at Lu Lao, who was still sitting cross-legged.

This time he came in such a hurry just to save Lu Lao, but fortunately, he came in time.

Goodbye Lu Lao, it's been a few years.

Xu You vaguely remembered that he was just an ordinary outer disciple in the Hanjian Gate, but he met Lu Lao outside the Refining Peak Scripture Pavilion, and after a few salutes, he received a gift from Lu Lao, otherwise, Xu You would not have been able to learn the art of the wooden puppet later.

Although nowadays, the art of the wooden puppet is already dispensable for Xu You, but for Xu You at that time, the help of the wooden puppet technique was too great.

It is no exaggeration to say that without the help of the wooden puppet, Xu You would have died in countless dangers, and without the wooden puppet, there would be no Xu You today.

Xu You has always been gracious, and Lu Lao is undoubtedly a great favor to him.

At this moment, when he met Lu Lao again, Xu You did not hesitate and made a big gift to meet his master.

"Is it you?" Lu Lao opened his eyes at this moment, and also recognized Xu You, he was also extremely comforted at this moment, he was just doing it casually back then, seeing that Xu You had a good character, so he taught Xu You the art of the wooden puppet, but he didn't expect that the unintentional act of the year actually achieved a realm master today.

Although Lu Lao is guarding the demon cave and serving as a tomb guard, he also knows about the Hanjian Gate and the things outside, of course he knows the realm of Xu You now.

In terms of refining weapons alone, Xu You is already much higher than him now, after all, Xu You is a realm master, but Lu Lao is not, but he is just specialized in the art of wood puppets.

At that moment, Lu Lao wanted to help Xu You up, but Xu You had to do this no matter what.

According to Xu You's words, he doesn't talk about cultivation as a realm, only about seniority, Lu Lao is his predecessor, and he is the master who taught him the art of wooden puppets, this kindness cannot be forgotten, no matter how high his cultivation is, the other party is still his master.

"Yes, yes. Old Lu was relieved, and a warmth welled up in his heart.

It's just that thinking of the current situation, Lu Lao hurriedly said: "Xu You, you go quickly, that person is this Demon Cave Demon Lord, although he is only a clone, but his strength is strong, he is comparable to Yuan Ying, you go back quickly, and tell Su Ji that you must not send someone here, you must find a helper to resist this Demon Lord from going out to harm the world." ”

Xu You listened but was unmoved.

Lu Lao was anxious, and said: "Xu You, don't be reckless, go quickly." ”

Xu You shook his head.

In the past, Xu You overhauled the Yuan Baby, and he didn't have any way to deal with it, but now, Xu You is no longer the same person he used to be, if the other party is a god, Xu You may still be a little worried, but it is only at the Yuan Infant level, to be honest, he can't scare Xu You.

Lu Lao couldn't do it in a hurry, but Xu You didn't leave, and he couldn't do anything. The clone of the demon lord over there was already furious, and said angrily: "Where did the hairy boy come from, he actually regarded this seat as nothing, looking for death!"

After speaking, there was a burst of shouting, and countless black mist immediately poured out of the surroundings, covering the sky and the sun, like a tide, rushing towards Xu You and Lu Lao from all directions.

"Be careful, those black mist must not be contaminated, otherwise it will be entangled immediately, once it enters the body, the soul will be devoured by these monsters, and it will definitely die. Lu Lao hurriedly reminded on the side.

At the same time, Lu Lao pinched a trick, and the only remaining wooden golems around him immediately rushed towards the black fog, but the wooden puppets did not have the slightest lethality to the black fog, but all kinds of claws continued to emerge from the black fog, constantly attacking the wooden puppets, and the remaining more than twenty wooden golems were broken and dismembered in just a moment, and scattered all over the ground.

Just by seeing this scene, you know the horror of these black fogs.

Xu You's face was also solemn at the moment, obviously, ordinary means did not do the slightest harm to these black fogs, the black fog had no form, and it could change at will, it was indeed difficult to guard against.

But fortunately, Xu You had already been in contact with this black fog before, and he had fought with it.

So Xu You knows how to deal with these black fogs.

Seeing Xu You take out a magic weapon, he threw it away, and this magic robe flew out confidently and wore it on Lu Lao's body, and the next moment, a raging flame appeared on the magic robe.

The only thing that the black mist was afraid of might be the thunder and lightning flames, so they avoided Lu Lao at this moment and all flocked to Xu You. And Xu You, motionless, didn't seem to think about resisting and resisting at all.

The next moment, black mist was engulfed.

"Look for death!"

The Demon Monarch clone sneered at this moment, seeing so much black mist wrapped around the kid just now, he was already relieved, no monk could get out under the invasion of so many black fog, maybe this time it would lose a lot of black mist, but as long as he could kill this troublesome kid, it would be good, because the Demon Lord clone keenly felt that this person who suddenly appeared was not simple.

It is best to kill such people as soon as possible.

I thought it would take some means, but I didn't expect the other party to be wary at all, even if it was a Yuanying overhaul, if it was so entangled in the black fog, it would definitely die.

As for the flame cloak on Lu Lao's body, although it is a little troublesome, as long as some black mist is lost, the flames on the robe can still be directly annihilated and the other party will be occupied.

Thinking of this, the Demon Lord clone had already stopped looking at these two people, thinking that if he had known that it was so troublesome, he should not have considered saving power in the first place, but adopted a plan to slowly erode that Lu Lao, if he had called a large amount of black mist at the beginning, Lu Lao would have been controlled by him a long time ago.

It's just that at this moment, the Demon Lord's clone, who was originally in control of the victory, suddenly noticed something, and looked at Xu You, who had been wrapped in black fog and couldn't see the figure, with a look of astonishment.

Slowly, the expression of the Demon Lord's clone changed from shock to horror.

"Not good!"

The next moment, he wanted to mobilize all the black fog to escape from that person, because just now he actually found that the black fog that was extremely important to him actually began to be dissolved in an instant.
