Especially the size of this formation, which made Si Cheng feel shocked, he had never seen this huge formation in the cultivation world before, even the ghost spirit formation was not comparable at all.

"What is this?" Montaigne was also shocked at the sight!

Yuan Gang's expression froze, looking at the huge shrouded light curtain, he also opened his mouth, and then his face changed greatly.

"Hurry up, this is the formation!"

Montaigne's face turned pale when he heard this, he hadn't heard of the formation, he had even seen it once, and at the same time, he also understood the horror of the formation.

"Retreat!" Montaigne didn't have time to think about it, he let out a loud roar, and at the same time, he himself quickly retreated towards the rear.

"Hmph, since you're here, why are you leaving?" A faint voice suddenly sounded from the air, and then the light curtain became larger again, directly enveloping everyone.

Si Cheng frowned in the distance, these city guards were shrouded in the formation, and now they couldn't see anything, unless they also entered it.

However, Si Cheng would not commit such a nerve, he didn't know what kind of formation this was, and he didn't know what the situation was inside, and he wanted to take the initiative to go in, it was purely a problem with his head.

"Boy, don't hide, I found you a long time ago, come out!"

Si Cheng held back his mouth and made a helpless expression, and then walked out directly, looking at the person in front of him, Si Cheng was really surprised.

Because this person is still extremely young from the outside, this is really very different from those Dao Venerable Realms in the cultivation world.

Unless it is a new generation of young powerhouses who have entered the Dao Venerable Realm, they all look like old dragon bells, at least they don't look young anymore.

"You were the one chasing me that night!"

"Not bad!" Si Cheng raised his head and said directly without denying it.

"Oh, that's a pretty straightforward answer, but why are you chasing me, and how did you find me?"

"I ......" Si Cheng suddenly stopped when he said this, would it be a little inappropriate for him to say his identity rashly.

Si Cheng felt that it was better not to say it for the time being, because he was not familiar with this person at all, and if he announced his identity, he would really become a rat crossing the street.

This kind of thing can't be without, this person is now being chased by the city guards, and it is very likely that the city lord of Qitong is also paying attention, if he pushes himself out directly in order to lure away the city guards, such a situation is very likely to occur.

Si Cheng smiled slightly, saying that he accidentally saw a figure that night, and he chased after him out of curiosity, but the other party obviously didn't believe this explanation.

"My name is Duan Zhengyu, how about making a friend!" Duan Zhengyu not only did not get angry at Si Cheng's lie, but also lowered his posture slightly.

Si Cheng's expression was stunned, he didn't know why this person would say such a thing, but since everyone said so, he smiled slightly, and then nodded.

Naturally, there is no problem in making friends, you must know that you were also an upright Dao Venerable Realm cultivator before, and it was a powerful Dao Venerable Realm that had experienced the Colorful Thunder Tribulation.

I can be fully worthy of it in terms of identity, and I want to get some useful information from the other party, and it's also very good to make a friend, how to say it, it's just what I want.

However, at this moment, Duan Zhengyu's expression was condensed, his brows were furrowed in vain, and his eyes were also looking into the distance.

"Someone is coming, do you want to avoid it!"

Si Cheng nodded, and then ran to the side, to be honest, he hadn't sensed that someone was coming, but Duan Zhengyu, as a Dao Venerable Realm cultivator, could naturally find out in advance under his divine sense.

Si Cheng squatted in a relatively hidden place, watching the development of things in front of him, but Duan Zhengyu was smiling at this time, looking into the distance.

"Hehe, is the city lord? Your baby still needs some heat to use, you came just in time, these small fish and shrimp are really not enough!"

It didn't take long for Si Cheng to sense movement in the distance, and when he looked intently, he saw three figures rushing towards this side.

The leader was a white-bearded old man, followed by a black-haired old man and a big man, who were also solemn at this time, and were quickly coming here.

"You are the cultivator who stole my essence source?" As soon as the three of them came, the white-bearded old man at the front asked directly.

"Haha! Yes, you uninformed natives, the essence source will only be ruined by you, it is better to give it to me, besides, this can't be called a thief, I took it!"

"Jingyuan?" Si Cheng, who was peeking in the distance, also silently recited these two words in his mouth, as if he had never heard of Jingyuan.

"Haha, Si Cheng, this is a good thing, Jingyuan! I really didn't expect there to be such a good thing here!" Just when Si Cheng didn't know what to do, the voice of the heart of space suddenly came.

Si Chengqiang resisted the urge to pinch him to death directly, relieved his breath, and then asked, "What is the essence source?" Could it be the lost treasure of the City Lord's Mansion?"

"Hey, it's not wrong to say that it's a treasure, Jingyuan is in the cultivation world that you used to be so poor that it can't be described, it's simply impossible to store zài, and he doesn't deserve the title of treasure!"

Si Cheng was taken aback, the heart of space simply blew the essence source into the sky, and it was not even worthy of the treasure, so what else could it be called.

"Didn't you encounter an Earth Moon Essence some time ago, and you ate it directly!"

Si Cheng nodded, at that time, it was also the heart of space that said that the earth moon essence could restore his cultivation, if he did, he would naturally eat it, and it was too little.

"Hehe, and the essence source is that those essences have mutated, and it will take countless years before they can be formed into the source!" the Heart of Space then continued.

"Source, what is that?" Si Cheng asked again.

"The reason why it's called the source is because this essence is no longer the same as the last time you encountered it, but has formed a crystal, so it's called the source!"

Si Cheng nodded, and it was clear in his heart that the heart of space explained it like this, the source was just a name, and when this kind of source was first discovered, people named it the source, and it was the source.

"What is the use of that Jingyuan?" Si Cheng planned to break the casserole and ask to the end, because since Jingyuan was called a treasure, it should have a great effect.

"The effect is great, for cultivators, it is the real supreme treasure, because he can be directly absorbed by the Dao God and improve the quality of the Dao God!"

"Dao God also has quality?" At this moment, Si Cheng involuntarily said, this is the first time he has heard of this kind of thing.

I only know that there are several types of Dao gods, such as my own colorful Dao God, which is a kind of existence that is different from the general Dao God.

But the Taoist God still has quality, this is really not to say that I don't know, I was directly shocked when I said it!
