As we got closer to the demon battlefield, more and more people appeared on the road.

The guarding became increasingly strict, with a guard post almost every five steps and a sentry every ten steps.

Yuan Ran suppressed his confusion and explained to Gao Han and his uncle-master that in order to prevent humans who had been assimilated or possessed by demons from slipping through the cracks, entry and exit of the Lingtian Continent were strictly controlled in all places.

"In the early years, there were many traces of demons among the people. One sect was destroyed because a demon infiltrated it."

"Are demons so scary?" Gao Han said in surprise. "During the previous illusion test, I heard the phantom inside say that the best way to identify demons is that they cannot use spiritual power."

"That's true, but there will always be some who slip through the net." Yuan Ran said helplessly, "There are too many people coming to the Demon Battlefield. It's impossible to ask everyone who comes in and out to show their spiritual power."

"And over the years, the demons have learned how to deal with it, so it's possible that they've faked it."

"How did that sect fall?" Gao Han asked again.

"It's actually bad luck for that sect. The one who was possessed by the demon was an elder of the sect, who was in a high position and had great power. Who would have dared to investigate him? Who would have thought that he would be possessed by a demon?" Yuan Ran sighed.

"When this incident broke out, there were only a few monks left in the entire sect who had not been assimilated."

"If it weren't for the fact that a few disciples of that sect got into a fight and were found to be demons, the other major sects would have investigated and found that many disciples of that sect had been assimilated into demons. They wouldn't have discovered that their leaders, including the sect leader, had also turned into demons."

Talking about this incident, although Yuan Ran did not participate in it personally, after all, it happened quite a while ago, but he had heard about it from other people, and thinking about that scene, he still felt scared.

Gao Han thought for a moment, "If a sect is found to have all been assimilated into demons, then the humans who have come into contact with them must also be examined."

"Of course, this incident caused a big stir at the time, and everyone was in danger."

Yuan Ran thankfully said, "Fortunately, it takes time for demons to assimilate humans, especially powerful cultivators."

"Are there any characteristics or special manifestations during assimilation?" Gao Han asked. This is the most important thing.

"The temperament of demons is different from that of humans. Their personalities will be different from their usual performances. The identification of spiritual power will only be revealed after complete assimilation."

Gao Han raised his eyebrows slightly, "In this case, before being completely assimilated, there is no better way to determine whether it is possessed by a demon."

"That's right." Yuan Ran nodded.

What he didn't say was that a lot of people were implicated because of that sect, and some were even wrongly killed.

The policy adopted by many major sects in dealing with demons is that they would rather kill the wrong ones than let one go.

"However, not everyone can be possessed." Yuan Ran was afraid of discouraging them, so he quickly said something good.

Gao Han was surprised and said, "There is such a saying."

“Of course, otherwise the Lingtian Continent would have been destroyed long ago when the demons first invaded.” Yuan Ran said with a smile.

"Then what kind of person cannot be possessed?" Gao Han asked.

"A powerful cultivator will be crushed to pieces as soon as an ordinary demon possesses him. The elder of the sect who was possessed was at the Nascent Soul stage, and the demon that possessed him was also a great commander corresponding to the Nascent Soul cultivator."

"On the other hand, if it was a commander-level demon that possessed him, the Nascent Soul Elder might not have been assimilated."

"Generally speaking, if the cultivation level of a human cultivator is lower than that of a demon, the faster they will be assimilated. If their cultivation levels are the same, then it depends on who defeats the other first in a short period of time."

Gao Han's mind was moved, "Was that Yuanying elder defeated in one fell swoop?"

Yuan Ran shook his head, revealing a trace of helplessness. "I don't know, maybe it is, maybe it isn't, but the result is the same. Once discovered, whether you have been assimilated or not, you will most likely face the fate of being strangled."

Gao Han asked: "Is there no way to catch the demons in the bodies of the cultivators who have not been assimilated?"

Yuan Ran sighed and said, "Yes, there is, but it only targets the cultivators who have just been possessed. If the Yuanying elder had not been assimilated at that time, then the demon must have possessed him for quite some time..."

When Gao Han saw that he didn't continue speaking, he understood.

The Yuanying elder did not reveal the fact that he was possessed by a demon at that time because he did not want to die. However, he ended up harming the entire sect and the innocent people who were implicated by him.

When they arrived at the entrance of the demon battlefield, the two of them stopped talking.

The entrance is full of towering, steep and rugged mountain peaks, towering into the sky.

This is the Forbidden Mountains. On the surface, it is a naturally formed terrain, but in fact, the Forbidden Mountains are man-made.

When the demon battlefield was opened up, in order to prevent human monks from accidentally entering and being strangled by the power of space.

In order to prevent the demons from entering the battlefield as if they were in no man's land, a terrain barrier was set up. It almost surrounds the entire East Continent and is particularly spectacular and huge.

Only after entering the Forbidden Mountains can you see a magnificent city standing between the dangerous peaks.

This city has neither magnificent buildings nor carved beams and painted rafters, but its flying eaves and brackets seem to reach the sky, displaying an unyielding spirit.

Gao Han and Zhongli Tingzhou were walking on the streets of the city. The monks who were coming towards them all had a murderous aura and a thick smell of blood.

Looking at the magic weapons in their hands, they were still stained with a little fresh blood. That was the blood of demons, and the smell made them excited.

"Many of the people in the city have just come out of the demon battlefield." Yuan Ran explained as he walked.

Gao Han noticed that the stalls here were very different from those in the trading area of ​​Zixiao Sect.

Human monks can be seen everywhere selling things obtained from demons.

Why do human cultivators like to come to the demon battlefield for training? Besides the fact that this is the Eastern Continent of Lingtian, there is another important reason: certain parts of the demon's body can be used as materials for refining weapons or elixirs.

It is rarely seen in the trading area of ​​Zixiao Sect, but here, it can be seen everywhere, including monsters.

Yuan Ran saw him looking at the things on the stall and smiled, "Many people always get things they don't need. This city is the best trading point, and the chance of encountering good things is relatively high. When we get outside, everyone will divide their things, so we can only go to the trading point to see if we can encounter what we want."

"Here, most people barter and exchange spirit stones. However, if you want to exchange demon heads for contribution points, you can only do so in our sect."

Gao Han knew this, and after looking for a while, he looked away.

It’s not that I don’t want to see it, but I don’t have the spirit stones, so it’s useless to see it more.

They are not here to buy anything.

Cities near the demon battlefield are not allowed to fly. Unless you are a powerful monk, you have to walk or use a teleportation array.

The person guarding the teleportation array was a cultivator from the Zixiao Sect. He knew Yuan Ran, but he still wanted to collect spirit stones.

Different sects have different rules, but in the Zixiao Sect, everyone is equal.

Seeing that Zixiao Sect’s own cultivators also had to charge teleportation fees, some outsiders felt relieved.

"Yuanran, are you bringing your fellow disciples to complete the mission again this time?" The young cultivator on guard had a cultivation level similar to Yuanran's, both were in the Jindan stage.

Since Yuan Ran would usually bring his fellow disciples to the Demon Battlefield to complete missions, this fellow disciple took the initiative to take over.

Yuan Ran secretly glanced at Zhongli Tingzhou, and seeing that he was not angry, he breathed a sigh of relief and explained in a low voice: "Don't talk nonsense, this time it's not my junior brother, it's my great-uncle."

The young monk opened his mouth in astonishment. Such a young great-grandmaster?

Could it be that Yuan Ran was frightened by the demon and had a fever? Although he has been guarding the teleportation array here, he has only been here for a few years. There are no uncles in the sect who are so young. But Yuan Ran would not save himself.

Yuan Ran did not dare to explain too much in detail in front of his great uncle, so he transmitted his voice to the young monk, "He is a disciple that my great uncle just accepted a while ago, but he should not be too conspicuous when he is out."

There is only one great uncle master in the entire Zixiao Sect. The young cultivator now understood.

He immediately put away his nonchalant attitude. The disciple of the great-grandmaster's uncle was of a very high generation. It was better not to offend such a person.

He respectfully sent the person into the teleportation array, and the young monk breathed a sigh of relief when the person was teleported away.

The teleportation array does not teleport directly to the Demon Battlefield, but to the exit of the Demon Battlefield.

An entrance and exit that can accommodate more than a dozen people at the same time, with a light blue halo, like a water curtain, and the demon battlefield can be vaguely seen from the outside.

The three people passed through the aperture, their bodies seemed to melt into the water, the aperture rippled lightly and then disappeared.

An even stronger murderous aura came towards him, and the first thing Gao Han saw when he saw the battlefield of demons was desolation.

The demon battlefield behind the aperture is also a city, and an old city at that. The black brick walls are covered with spots, which are the traces of past battles.

"Such an old city?"

"It's been thousands of years, but it has been rebuilt and is still in good condition."

"Does the demon army often attack the city?" Gao Han asked.

"They used to come often, but after the battle line moved to the rear, they came less often. Now they mostly attack by surprise, so you have to be careful at night. When you sleep, don't sleep too deeply, and it's best not to practice. When strong men fight, the aftermath is very likely to shock people to death. These have happened before."

Yuan Ran said as he led them to find the people guarding the city.

"Yuanran?" Hearing that someone was looking for him, a middle-aged monk walked out of the earthen house and saw a familiar figure.

"Uncle Qin." Yuan Ran called out to the middle-aged cultivator, and immediately turned to Zhongli Tingzhou and said, "Uncle Master, this is Uncle Qin Changsheng, from Luojian Peak."

Qin Changsheng was surprised when he heard Yuanran calling a young cultivator "grand uncle". What kind of great uncle was this? He just hadn't been back for a while.

"Uncle Qin, my uncle-master is the disciple that our great-uncle-master just accepted a while ago." Yuan Ran explained in a low voice.

Qin Changsheng's expression froze slightly, and he raised his hands stiffly, "Changsheng greets Uncle Master."

"No need to be so polite." Zhongli Tingzhou had a cold expression. Since arriving at the demon battlefield, he had returned to his original nature.

At first glance, Qin Changsheng thought he saw his uncle-master.
