Linglong was shocked because there was an evil demon that he couldn't do anything about.

To be so humble in front of this person, even begging for a chance to live but not getting it.

"This person is covered in black mist. I can't rest assured that he is also a demon cultivator..."

As he thought this, the aura on his body slowly began to gather. He planned to try his best. This might also be his only chance.

"Don't you see? I am slaying demons and defending the law!"

Zuo Yan didn't open his mouth, and his voice seemed to appear out of thin air, with a particularly strong accent.

It is a special method created by using the fluctuations of surrounding spiritual energy. (For specific information, please refer to Sister Yaya, the Little Fox Matchmaker.)

"Exterminate demons? I believe you are a ghost." Thinking like this, Linglong asked: "How do you know it's him here?"

"You can detect such a huge amount of demonic energy just by sensing it, right? And this Heavenly Demon Sect..."

"Hehe, boy, if you wait until the Demon Sect appears completely today, I'm afraid your city will be gone in an instant..."

Linglong was shocked and his face turned ugly.

The appearance of the Demon Sect is very rare, and it has only appeared once in the past hundred years.

But that time, three demon lords and a half-step demon saint appeared in the Tianmo Sect.

This strength is almost comparable to that of some holy places. With the strength of his city, it is really difficult to resist it.

Suddenly he seemed to remember something, his face lit up, he looked at Zuo Yan and said:

"Senior, isn't he slaying demons and defending the Way? Does this senior of the Heavenly Demon Sect have any ideas?"

"In this case, I think it's better for you to move quickly."

Zuo Yan said while taking care of the soul demon.

"Senior, don't worry. I have already notified the powerful people in the Holy Land, but it will still take a few days to arrive. In the meantime, can senior..."

“Boohoo!!”

At this moment, a huge spiritual power and powerful soul power burst out from underneath.

Zuo Yan narrowed his eyes slightly and moved his hands to combine and smelt them together.

But as soon as it came down, there were dozens of black and white elixirs floating in the air, emitting a strange aura.

Zuo Yan reached out to take it, and took a sip directly in front of Linglong. His whole body was shaken, and his cultivation had broken through to the three veins of the dragon's spine.

The Spirit Dragon on the side showed a shocked expression for a moment, but he covered it up within a moment.

Impossible is all illusion. How could the person in front of me be just a second-level and third-level novice...

"Hehe, most of my strength is reflected in formations. You have done quite well with this one-line sky city defense formation. It depends on whether you have the courage to leave it all to me..."

Zuo Yan turned around and said, but he was surrounded by black energy and couldn't see clearly. This appearance made Linglong even more afraid.

One thing to say is that the city defense formation in Xiantian is quite advanced. At least now if he wants to control it all, he will have to spend at least three to five days here.

"This..." Linglong was speechless for a moment. The city-protecting formation is equivalent to the sect-protecting formation in the sect's holy land.

How could he not be embarrassed by letting an outsider take control of the trump card that he would not activate until the last moment?

Seeing him like this, Zuo Yan continued:

"Actually, it doesn't matter. I feel an extremely powerful spiritual treasure from your body. That aura should be a magic weapon to suppress demons, right?"

"With it and you, it won't be a problem to last for three to five days."

"Okay, the matter has been taken care of. I have other things to do, so I'll leave first. See you later."

Zuo Yan said, raising his feet and walking out without any intention of treating himself as an outsider.

However, when he was about to reach the corner, the spirit dragon moved.

"Wait, senior!!"

"Oh, do you have anything else to do here?" Zuo Yan turned around.

"I agree, but I have a request."

"explain."

"I hope that after senior takes control of this great formation, he can purge all the remaining demons in the sky, is that okay?"

Obviously, when he went out to talk just now, he had already learned what happened today from those people's mouths.

"Okay." After thinking for a while, Zuo Yan nodded.

He has also seen that large formation, and after mastering it and modifying it, it is quite easy to deal with those below the eighth level.

"Here, this is the specific situation of the formation!"

Linglong said, throwing out a yellow drawing, Zuo Yan took it and walked out without looking back.

If she had a choice, she didn't want to be exposed, but there was no other way.

If he waits to use this magic needle ruler, the demons that have already escaped will immediately besiege the city lord's mansion.

"But fortunately, this guy has solved this demon, otherwise we would have to waste more energy to suppress it..."

"I hope I don't have any bad intentions, otherwise..."

He also has some backup plans.

…

"Interesting. Is this training my control over the formation?"

Zuo Yan smiled slightly at the drawing in his hand as he just wrote some basics of the formation on it.

How to control it was not mentioned at all, but the master didn't care, it was enough.

In less than half a day, he could completely control the formation.

Then he took two more soul pills that he had just practiced, and then headed towards the door.

The grade level is not high, around level 6, but for Zuo Yan at this time, it is quite strong, and he needs to take a nap to digest it.

If he were swallowed by an ordinary person at the same level as him, he would probably explode and die instantly...

Walking to the small courtyard, after doing some processing, he walked in. Looking at Li Shiyi who was still sleeping soundly, he walked in and held her in his arms.

While looking at her, his spiritual thoughts spread out, sensing this large formation.

The center of this great formation is in the City Lord's Mansion, and he is here now.

In this way, time passed little by little, and his control over this formation continued to increase.

Finally, an hour before dawn, he felt that he could initially control this formation.

You just need to wait for a suitable opportunity, turn it on, and then use its power to annihilate those monsters and monsters in one fell swoop.

…

However, accidents always come before plans. In that corner of the demon world, I also discovered something that made people laugh or cry.

"Ahhhh!!!"

"Is there something wrong with you? You know that place is the main base of the gate, but you still insist on rushing in!!"

"Is there anything I can do? With my strength, I can only use the boundary-breaking needle to open the space fluctuations of that level. Otherwise, we are just waiting to die here. I will give it a try. Am I wrong?"
