This dark gray ancient city is like a long-sleeping beast, standing silently on this grassland.

Su Chen, who followed the old man to the city gate, couldn't help but slow down at this time, staring straight at the mottled city walls, his heart full of doubts.

Why is there such a city in the Taiyuan Realm, and isn't this the place where the master's boundary is located?

Just as every outer disciple can be equipped with a cave mansion when they first enter the sect, every inner sect elder who has reached the level of the god realm or above will also have a realm of his own within the sect.

And a big Luo like Shizun Shi Lao, the sealing area he can have is even more terrifying, which can be seen from the comparison of the size of these light masks outside.

"Senior, what's going on in this city?" Su Chen looked at the back of the old man in front of him, and after thinking about it, he decided to ask.

Hearing Su Chen's question, the old man who had not spoken all the way finally stopped, turned his back to Su Chen and said, "Little master, you don't have to call me senior, just call me senior." ”

"As for this city, there is actually nothing to say, the master has already moved all the family members from the outside world to the Taiyuan Realm when he stepped into the Tongshen. At the beginning, it was just a small family of more than 100 people, but now hundreds of years have passed, and there are no wars and natural disasters here, under the breeding of generations, the current Shi family is already a super family with a population of tens of millions. ”

A family with a population of 10 million!

Su Chen was almost choked by the old man's understatement!

In hundreds of years, a small family of more than 100 people has become a super family with a population of 10 million, how does this sound a bit mysterious?

But as Su Chen calmed down and thought about it carefully, he found that this was indeed the case, after all, the people in this world are not like their previous lives, and there are any so-called family planning and other constraints, it is too common for them to give birth to three or four heirs in their lives, and even some more attentive martial artists will have more than 100 heirs under their knees because of their long lifespan!

If you count it from generation to generation, human reproduction is like locusts, terrifying......

At this time, the old man in front turned half of his body and glanced back at the surprised expression on Su Chen's face, and a rare smile appeared on his old and decrepit face.

His name is Lao Yu, and he has been by his master's side since he was a child, responsible for serving his master's daily life, and now hundreds of years have passed, and the little boy has already become an old servant under the blade of the years.

Especially in recent years, as a martial artist, he has faintly felt that his life may be coming to an end, and it is really a thing that makes him very happy to see his master's martial arts successor in his last time.

"Little master, this city is called Shiqian, it is a small city on the border of the Taiyuan Realm, and the people who live here are basically the children of some branches with thin blood, and the place we are going to is located in the very center of the Taiyuan Realm, and we need to use a teleportation array here to divert the route. ”

"It's getting late, let's go. ”

After the old man whispered a word to Su Chen, he continued to walk towards the city gate, step by step, just like a most ordinary mortal old man.

Su Chen slowly recovered from the initial shock, and quickened his pace to follow the old man with a strong mysterious aura, because his intuition told him that this old man named Lao Qi did not seem to be as simple as he seemed on the surface.

At this time, a team of ironclad soldiers stationed on both sides of the city gate frowned after seeing the inexplicable appearance of an old man and a young man.

"What are you two doing!"

At this time, an ironclad soldier at the head stepped forward, stopped the halberd in his hand in front of the old man, and asked in a cold voice.

Seeing the leader's words, the other soldiers also gathered around.

The old man who was stopped by the soldiers was not angry, but slowly took out a dark blue jade plaque with the word "stone" printed on it from his arms.

"Do you see clearly?" The old man's voice was unwavering.

And at the moment when he saw the jade plate, the heart of the leading soldier instantly rose into a stormy wave, and his scalp was numb for a while!

"You...... Is it the main lineage? ！”

As soon as these words came out, the soldiers who surrounded them immediately trembled in unison, and they were a little at a loss.

"I'm going to borrow the teleportation array in this city, and you'll have someone to show me the way. The old man commanded.

"Shangjia, you want to borrow the teleportation array of our Shidui City, but don't all of your main veins have special ......," the leading soldier asked with a wincing face.

Because he is not a member of the main line. The old man pointed to Su Chen, who had already walked behind him, and the meaning was already very clear.

"I see, then come with me, and I will show you the way. The leading soldier nodded after a little silence, not daring to ask more.

"Alright, I'll take them to the teleportation array, and you will continue to guard here. ”

The leading soldier briefly explained a few words to his subordinates, and then led Su Chen and the old man into this stone city together.

After entering the city, Su Chen found that it was already late at this time, and many of the houses on the side of the street had already closed their doors and lit candles, so the avenue seemed a little deserted.

However, this was also convenient for Su Chen and the others, and there was no stop along the way, and after turning around a dense building complex, the teleportation array of this Shidui City finally appeared in front of Su Chen's eyes.

"Shangjia, this is the teleportation array, you just need to put the Yuan Crystal on the corner and you can use it. The soldier said.

"Alright, there you go. The old man waved his hand.

"Yes. The soldier clenched his fist and walked away quickly.

After the soldier walked away, the old man cleared his throat and slowly turned around, and said solemnly to Su Chen in front of him: "Little master, before taking you to meet the master, the old slave has a few words to remind you, I hope you will remember." ”

"Senior, you say. Su Chen hurriedly responded.

"I said don't call me senior, I'm just an old slave next to my master, I can't afford to be the 'senior' of the little master, just call me my old master. The old man said with a smile.

"Old ...... Boss. Su Chen was still a little embarrassed.

The old man smiled and continued: "The little master of the Nine Great Dao Realm of the Dao Dust Sect must know, but for the true meaning of the word Dao Realm, has the little master ever known?"

Dao Realm?

Isn't it just a floating continent......

Su Chen couldn't help but be a little puzzled when he heard this.

"I don't know. ”

The old man was not surprised, nodded slightly, and said:

"The so-called Dao Realm is the realm of ten thousand Dao!"

"Every martial artist in this world who wants to step into the realm of Tongshen needs to realize at least two great avenues, and engrave them in his flesh, bones, and even divine souls. In fact, it is quite easy to engrave the Tao on oneself, after all, it is born from the same origin. ”

"But what if a martial artist wants to leave the Great Dao of his enlightenment in this heaven and earth?"

"Leave a mark on heaven and earth?" Su Chen was also a little staggered.

"That's right, but throughout the ages, only the Supreme has been able to do this, so if you look at it this way, these seem to be some ethereal and undesirable things, but in fact, they are not, and many times we might as well retreat to the second. ”

The old man paused for a moment when he said this, and after thinking about it for a while, he continued: "The predecessors and sages of the Dao Dust Sect created a secret method of sealing the realm that could carry the Dao seal by chance. ”

"Through this secret method, a martial artist can open up his own realm after reaching the realm of the gods, and engrave his own Great Dao imprint within the realm. ”

Hearing this, Su Chen couldn't help but ask, "Even so, what good is it for those martial artists who have passed through the Divine Realm to burn their Dao seals in the Sealed Realm?"
