Since we are close to Dutian Castle, we can only see a small section of the entire castle wall and the open steel gate within our view.

The city wall is made of common stone in the world of immortal cultivation. It is about four or five meters thick. The surface is grayish-white and slightly rough, but its hardness is not weaker than ordinary steel. Even if it is attacked with ordinary swords, it can only leave shallow marks on its surface.

Of course, this city wall is not the main defense method of this large castle. For immortal cultivators, even the most solid stone city wall is useless.

The lilac guard formation around the city wall is the backbone of Dutian Castle's defense, which puts the entire castle under its own protection.

Twenty mid-stage Qi Refining Cultivation Cultivation Cultivation Cultivation Cultivation Cultivation Cultivation Cultivation Passed through the city gate, and when they reached the city gate, they all consciously landed on the ground where the castle extended, and then walked in.

Zhang Heng discovered that every monk entering the castle would pay a crystal stone, and in the process, there was no dissatisfaction at all. When there were too many people, they even lined up obediently.

Zhang Heng was a little surprised. Those monks who were usually unruly had such a perverse day. The order of queuing up to buy train tickets on earth was even stricter. At least, there was no one who had been to go to the line.

Are these monks more qualified than those on earth? Of course, Zhang Heng would not think so.

Because this is a world where strength is the most respected, the reason why these monks are so well-behaved is because of the strength of Dutian Castle.

At this moment, a blue escape light flew over Zhang Heng and others in the sky, and a powerful aura flew through the surroundings.

The blue escape light was rectangular, a bit like Aladdin's flying carpet, with a blue halo flashing all over the body, much faster than the spirit control weapon.

There was a black-faced old man above the escape light. He rushed into the city without restraint by controlling the escape light. He did not pass through the city gate, but directly passed through the purple guardian formation above the city wall.

His behavior attracted the attention of many monks around him, but no one raised any objections. Most of them looked at him so casually entering Dutian Castle with awe.

The twenty guards at the city gate did not object at all, and turned a blind eye to let the man sweep into the city from the sky.

"It turns out to be a cultivator in the foundation-building stage!" Zhao Rui looked excitedly at the disappearing light in the sky, and said with a little longing expression.

Zhang Heng was speechless. At least those who could use the light-exiting technique were cultivators in the Foundation Establishment stage. Some advanced light-exiting techniques were much faster than those who could control the spirit.

"Okay, it's time for us to enter the city, and the foundation-building stage is not a very distant goal." Zhang Heng ignored Zhao Rui behind him and flew towards the city gate with his spiritual weapon.

"Yes, after giving me four or five years, I can enter the foundation-building stage. Hello! Wait for me..."

Zhao Rui flew quickly towards Zhang Heng, and his words attracted the attention of many monks around him.

After four or five years, the foundation-building period was entered? The monks around him looked at him with disdain, and some even mocked him.

"The guy who has not grown all his hair yet is still in the Foundation Establishment Stage? The senior brother of our school who has reached the Great Perfection of Qi Refining has not broken through the bottleneck for twenty years."

"You didn't see that he had already achieved the late stage of Qi Refining at such a young age. Maybe he could really enter the foundation building stage?"

"Don't think about it anymore. Now the foundation-building pill is almost extinct. There are so few people who can enter the foundation-building stage with their own efforts..."

...

Zhao Rui looked around a little embarrassedly, flew to Zhang Heng, and muttered in a low voice: "Is the foundation-building stage really that difficult?"

Zhang Heng said calmly: "For ordinary people with spiritual roots, there is indeed little talk. But if you have good skills or spiritual medicine assistance, people with spiritual roots will still have a greater chance of entering the foundation building stage."

"But I heard from my master that I am not a gifted spiritual root." Zhao Rui said in confusion.

"If you are not a talented spiritual root, then you are the legendary top-quality spiritual root." Zhang Heng said casually, but there was no envy in his eyes.

So what about talented spiritual roots? I have practiced the perverted skills and ignore the talent and will still trample on you to death.

Of course, Zhao Rui didn't know what Zhang Heng was thinking at this moment. He touched his head with his hand and smiled, "But I am not the best spiritual root?"

"It's not a talented spiritual root, nor is it the best spiritual root?" Zhang Heng was also confused.

Zhao Rui is only seventeen or eighteen years old, and his cultivation has reached the late stage of Qi Refining. His cultivation speed is simply terrifying.

No one believes that he is not a top-quality spiritual root.

"Then what kind of spiritual root are you? It's not a mutated spiritual root, right?" Zhang Heng asked with a strange expression.

"I am an ordinary spiritual root." Zhao Rui said in a weak tone.

Is this guy an ordinary spiritual root? Ghost believes it.

Zhang Heng ignored him, got off the spiritual weapon, landed at the city gate, and lined up according to the rules.

"Senior Brother Tang, I am really an ordinary spiritual root." Seeing that Zhang Heng looked disbelief, Zhao Rui hurriedly chased him behind him and lined up together.

Zhang Heng ignored his words and closed his eyes and rested.

Four kinds of spiritual roots in the world of immortal cultivation: waste spiritual roots, ordinary spiritual roots, talented spiritual roots, and top-quality spiritual roots.

Zhang Heng's physical body is an ordinary spiritual root. He knows the speed of his cultivation. It took more than ten years to reach the early stage of Qi refining, and it was also the result of a large number of spiritual medicines.

Zhao Rui is only at this age and has only been in the first place for two years. Even if he swallows any treasures, he will not have such a perverted effect.

"Oh, why don't you believe me?" Zhao Rui sighed depressedly, and stopped explaining.

After about a minute, Zhang Heng's eyes suddenly opened, and it was his turn to enter the city.

He gently patted the storage bag with his hand, and a crystal stone appeared in his hand, and Zhang Heng handed it to the guard opposite him.

"You can go in." The guard said with a cold expression, without looking at him again.

Zhao Rui also reluctantly handed over a crystal stone. Seeing that he was so young, the guard reached the late stage of Qi Refining, his expression calmed down a little: "Please come in."

This is the second time that Zhang Heng has encountered such unequal treatment today, and there is no expression on his face, so he takes Zhao Rui into the city.

The ground of the castle is paved with gray-black marble, flat and heavy, and when stepped on it, it gives people a sense of ease.

After entering the city, I found that there was a large flow of people inside, just like an mortal city.

Moreover, Zhang Heng also found mortals who were looking at them, a large number of cultivators in the Qi-inducing stage, and a certain proportion of cultivators in the Qi-inculation stage. Even at some point, you can see some cultivators in the Foundation Establishment stage.

There are many mortals selling some of the cheapest cultivation materials on the streets, among them, some of them shouting.

"The first-level peace of mind talisman is for sale, one hundred crystal stones."

"Five top-quality bear galls exchanged for one ordinary magic weapon."

"First-level talisman paper is for sale, and ten Yangqi pills are purchased."

...

Zhang Heng had an illusion, as if he had walked into a noisy ancient city, or as if he had entered a virtual fairy tale tour.

His expression was dazed, and he felt that it was difficult to distinguish between true and false about the world at this moment.

Is it a noisy ancient city, a system city for virtual tours, or a world of fairy tales in dreams?

His consciousness struggled violently in reality and illusion.

Suddenly, the mysterious jade tube in his mind released a tiny silver lightning, bombarding his mind heavily, making him awake instantly.

Zhang Heng's consciousness returned to this castle. He looked at everything around him with a new look: This is a cruel world, don't be lucky or escape, the road to go is still far...

Zhang Heng's psychological transformation process was only completed in an instant. Zhao Rui next to him did not notice it. He was curiously looking at the mortals around him, like a local bun in the city.

"Selling the heirloom treasure, and asking which monk to take this child as his disciple..." An old man in the Qi-inducing period shouted next to him, and there was a little boy of eleven or two years old next to him.

"Senior Brother Tang, let's go and take a look."

Zhao Rui shook his body and arrived there.

Zhang Heng's eyes lit up. Zhao Rui used some kind of body movement from Fan Shi.
