There was a moment of dead silence.

"Where is this?" Gao Han said and then he discovered a formation surrounding a city.

The fluctuations of the formation conveyed an evil aura, which was obviously not a good thing at first glance, as if it was stripping the vitality of the humans in the city.

Zhongli Tingzhou also sensed a familiar feeling from the formation, "It seems to be somewhat related to what was absorbed by the Samsara Pearl that day."

Gao Han's brows immediately furrowed, "Sacrifice?"

"It seems that the demon has not given up and is still planning to release that thing? Or is the target of this sacrifice someone else?" Zhongli Tingzhou looked at the demon Ken and the others with a smile.

The two demons felt their hearts tighten and their scalps tingled when they were stared at by him. They could see that the two human cultivators were very powerful, definitely stronger than them. It would be easy to kill them.

"What is the purpose of this formation? To sacrifice humanity to the demons, or to seal the Land of the Fallen?" Gao Han cast a cold gaze on the two of them.

The demons shuddered. They didn't answer, but they didn't sit there and wait to die either.

The two of them fled quickly in two directions almost at the same time.

They thought that at least one person could escape, but they didn't consider that Gao Han and Zhongli Tingzhou were also two people.

Just because Zhongli Tingzhou was the only one who took action at the beginning doesn’t mean Gao Han won’t take action either.

After discovering that the demons were planning to sacrifice humans, he had no intention of letting them go.

The two found that the space around them was fixed.

Ken's luck was better than his companions who escaped with him. The other party showed no mercy and he was killed with just a scream.

Ken's heart sank. Xiaowang City was so remote, how could a Mahayana monk get into trouble?

Almost all the Mahayana cultivators of the human race, even the independent cultivators, are in their intelligence network. They have planned this for a long time, and it is impossible for such a mistake to exist, especially with two Mahayana cultivators slipping through the net.

"Do you want to disappear like your companions and never be reincarnated, or do you want to answer our questions obediently?" Zhongli Tingzhou looked at him.

Ken was sweating profusely and slowly lowered his head. "The purpose of the formation is to sacrifice the human race. At least after the human race was sacrificed, we didn't know. The emperor just had someone pass on the order, and no one dared to ask the purpose of doing so."

"Where is the seal of the demon species?"

Ken suddenly looked terrified, "I don't know. The seal of the demon species is impossible even for a great monarch, let alone us."

Gao Han asked again: "Besides you, how many other people have received such a task?"

Ken hesitated.

Zhongli Tingzhou snorted coldly, and the sound was like a sharp silver needle piercing into Ken's mind. His soul felt dull pain and his clothes were soaked with sweat.

"In addition to us, there are eleven other people with the same mission. In this war, the Mahayana cultivators of the human race are either in other big cities or on the battlefield. Therefore, the emperor sent us to these small cities with only tens of thousands of people. We don't need too strong combat power, and we won't attract the attention of the human race's strong men all of a sudden."

Several small cities were sacrificed without anyone noticing, and by the time the human race's strongmen discovered it, it was too late.

Gao Han thought of the dark energy absorbed by the Samsara Pearl, and guessed that this sacrifice plan was most likely prepared for the demon's true body.

"Which are the other nine cities?"

Ken's eyes flickered, "I don't know. The mission is confidential. We only know our mission objectives."

An evil voice sounded in his ears, "Search your soul and you'll know if you know or not."

Ken was horrified and tried to resist but was unable to move as a hand covered his head.

After a while, everyone looked at the demon that had become silent, and then looked at Zhongli Tingzhou in awe.

A demon that had forced their city lord into a desperate situation was actually dealt with so easily, without even the slightest power to resist. The Mahayana cultivators were truly too, too powerful.

"My name is Shi Dong. Thank you two seniors for saving my life. I will never forget it." Shi Dong came up to the two men and bowed respectfully.

Gao Han nodded and said, "The current demon battlefield is different from the past. There is a boundary between humans and demons. Many small cities are no longer safe. City Lord Shi can consider moving to a large city where a Mahayana master is in charge."

Shi Dong had already thought about this problem after being trapped in Xiaowang City by three monarch-level demons.

He hesitated and asked, "Senior, what are these demon species they are talking about?"

"It is an extremely dangerous thing. In order to invade Lingtian Continent, the demons want to unlock the demon species and need life sacrifices. Now all human beings are their targets. If you can leave here, please leave."

Shi Dong was slightly surprised. He didn't expect the demon to have this trick. He quickly said, "Thank you for the advice, senior."

Gao Han looked at Zhongli Tingzhou, "Did you find any useful memories?"

Zhongli Tingzhou frowned slightly, "We only got information about two cities."

The demon resisted so fiercely that he had to forcibly search its soul, resulting in a lot of its memories being damaged, and there was not much useful information except garbage.

Shi Dong thought for a moment and asked, "Senior, which two cities are they?"

Zhongli Tingzhou glanced at him and said, "Dayu City and Xiaojiang City."

Shi Dong was slightly delighted. "These two cities are small cities, and the population won't be too large. I know where they are. The twelve cities chosen by the demons should all have a population of less than 100,000, and there won't be too many strong men stationed there. As for the other cities, perhaps we can guess some."

"oh?"

Seeing that the two were somewhat interested, Shi Dong continued, "I have been the mayor of Xiaowang City for a hundred years. I am very familiar with the Southern Region and often exchange information with the mayors of other cities. If you don't mind me being a hindrance, I can lead the way."

"In that case, thank you for your help." A second ago, Gao Han was worried that they were not familiar with the Southern Region.

"It's not a problem. Senior saved us, so this is the small thing we should do." At this point, Shi Dong became worried again, "But the demons may have sent people to other cities. I'm worried that we may not be able to make it in time."

"If we split our forces into two groups, we can always catch up with some of them." Gao Han had already thought about this problem. If the monsters acted at the same time, there would be nothing they could do if they couldn't catch up. After all, there were only two of them, so it was a blessing to be able to save some people.

Shi Dong calmed down and put away the worry on his face, "Senior is right, let's act now."

Gao Han said to Zhongli Tingzhou: "We don't know where Elder Tian is yet, so let's rescue the people in the other cities first."

Zhongli Tingzhou had no objection.

Feng Xinxing and his companions had left the place of fall before and should have informed Zixiao Sect. Letting the two of them search aimlessly would be like looking for a needle in a haystack and would only delay things.

Shi Dong immediately drew a map of the route.

Since the demon wanted to sacrifice twelve human cities without anyone noticing, the locations of the twelve cities must not be too scattered. Combining the geographical locations of Xiaowang City, Dayu City and Xiaojiang City, the locations of the other seven cities were quickly deduced.

Shi Dong divided the eleven cities into two routes, trying to get there as quickly as possible.

"Wait." Gao Han looked at the map and suddenly showed a strange look, "Did you draw the geographical locations of these cities according to their actual conditions? Or did you just draw them randomly?"

"Of course it is drawn according to the actual geographical location." Shi Dong didn't understand.

Gao Han said to Zhongli Tingzhou: "Do you think the locations of these twelve cities are strange, like a formation?"

Zhongli Tingzhou's research on battle formations was not as deep as his, but he could vaguely see it. He pointed at one of the places and said, "If we change it here, will it be more similar?"

Gao Han: “Yeah, I think so too.”

Most of the cities that Shi Dong guessed were correct, except for one or two, because they were tricks of the demons, but they were still seen through by them.

This was due to the fact that Gao Han had once studied a formation, the Seven-Star Tiangang Formation, and its counterpart was the Seven-Star Tiansha Formation. The latter was an extremely vicious formation, and once activated, all creatures in the formation would be turned into blood alive. It was an extremely inhumane formation, and was later banned by all major sects.

The Seven-Star Heavenly Evil Formation is based on seven stars and was very popular before it was banned. There was even a demon who specially improved the Seven-Star Heavenly Evil Formation, and the upgraded version is the Twelve-Star Evil Formation.

This formation is more vicious than the Seven-Star Heavenly Evil Formation. The imprisoned souls will never be reborn and will grow into extremely ferocious monsters.

It's like raising Gu, putting all the Gu in the same cave and letting them kill each other. The winner will become the most powerful creature in the world. However, the demons obviously don't want to raise such monsters. Their goal is to sacrifice them.

The Twelve Star Evil Formation can do the same thing. It can refine the creatures in the formation and turn them into the most evil monsters. Then, they can be sacrificed to the demon species, which can also increase the power of the demon species.

Monsters and demon species have the same attributes, so they can add up their power, which is why demons use the Twelve Star Evil Formation.

Shi Dong became even more anxious when he learned that the demon actually harbored such evil intentions.

"Don't worry, we have already destroyed one of their plans. Next, we just need to prevent them from finding out and activate the Twelve Star Evil Formation." Gao Han comforted.

Zhongli Tingzhou glanced at the route on the map, memorized a few cities, turned around and flew away: "Let's go."

Shi Dong glanced at Gao Han, and Gao Han said, "Since we already know the locations of the twelve cities, you should stay here to prevent the demon from sending anyone over again."

After saying that, he threw a communication jade slip to Shi Dong.

"If there is any problem, use the communication jade slip to notify us."

"Thank you, senior." Shi Dong was overjoyed.

Gao Han nodded and left, tearing through space and leaving. The space of the demon battlefield became more and more unstable as the war began. It was faster to walk through the space channel. One shuttle could travel thousands of miles, and it would be no problem to reach the next city in an instant.

Shi Dong stared at the direction where they disappeared with wide eyes. It was impossible for someone who had just advanced to the Mahayana stage to tear the space so easily.

He thought the two were too young and that they were newly promoted to the Mahayana stage, but now he is not sure.
