"Martial arts friends, when I first came to this Tianmu battlefield, I didn't know anything about the situation and rules here, I don't know if I can ask martial arts friends to introduce one or two, Ye is grateful. Seeing that Wu Ning's attitude was so friendly, Ye Fei took the opportunity to ask with his fists.

Judging from the friendly attitude of Wu Ning and the others towards him, Ye Xiaomu, Qin Xin and the others were definitely not injured by them, but Ye Fei did not directly inquire about who injured Ye Xiaomu and the others, but only asked about the situation and rules of the Tianmu battlefield.

"Ye Daoyou doesn't have to be polite, it's a little trivial, it's just a gesture. Wu Ning hugged his fists and saluted in return, and then stretched out his hand to ask.

"Please!" Ye Fei politely replied, and before following Wu Ning and the others to the city tower, Wu Ning waved his hand to the others, and led Ye Fei into a side hall of the city tower alone.

The side hall is not large, only less than 20 square meters, and a long table is placed in the hall, seven chairs are placed on each side, and a chair is placed separately on the top.

Behind the separate chair, on the left was a row of bookshelves, and on the right was a weapon shelf, on which only a sheathed sword was placed.

Wu Ning did not sit down on the single chair above, but pulled open the two chairs by the door, stood in front of one of the chairs, and stretched out his hand to invite: "Ye Daoyou, please sit." ”

"Please!" Ye Fei replied and sat down first.

After Wu Ning sat down, he took out a piece of jade slip from the Qiankun bag and put it on the table in front of Ye Fei and said: "Here is a basic overview of the Tianmu Battlefield, Ye Daoyou will take a look first, after reading it, if there is anything you don't understand, you can ask me, I will definitely know everything." ”

"Thank you!" Ye Fei clenched his fists and thanked him, picked up the jade slip and entered the spiritual power to check it.

According to Yu Jian, the Great Dao Universe only occupies one-third of the territory of the Tianmu Battlefield, and for tens of thousands of years, the Great Dao Universe has been in a defensive situation, building a Great Wall that winds for 60,000 miles on the border with the territory occupied by the Qing Netherworld Universe, so as to resist the attack of the Qing Netherworld Universe.

The 60,000-mile Great Wall is subdivided into 6,000 sections of city walls, each section of the city wall has at least one Immortal King high-level town, leading ten to twenty Immortal King Realm guards, every ten sections of the city wall is in charge of a Supreme Realm, and every 100 sections of the city wall is in charge of a Great Sage Realm.

The guards of the city wall are rotated every six months in non-war times, and in wartime, they are flexibly adjusted according to orders.

In addition to the guards of the city walls, there are a total of sixty cities in the Tianmu Battlefield, each of which governs a hundred sections of the city wall and is responsible for the logistics and supply of the city walls under its jurisdiction.

Immortal cultivators who were brought in from the Great Dao Universe and the Chaotic Star Domain, no matter who they were, would appear in a large isolated array outside the city wall at the beginning, and if they wanted to enter the city wall, they would either resist the pressure of the Supreme Realm of the city wall formation like Ye Fei, break through the barrier of the isolation array, and set foot on the city.

This situation is very rare, there will only be one in countless years, before Ye Fei, it was ten thousand years ago that he stepped on the city in this way.

Under normal circumstances, if you want to set foot on the city, you need to kill a cultivator from the Blue Netherworld Universe or survive in the Isolation Array for three months.

"I didn't know anything when I first came, and I had to kill a cultivator from the Qing Netherworld Universe before I could set foot on the city wall, didn't this make people die?" Ye Fei saw this, raised his head and frowned.

Wu Ning didn't answer, and stretched out his hand to signal Ye Fei to continue looking.

Ye Fei could only continue to look at the jade slip with puzzlement, it turned out that this was caused by a challenge by the top great sages of the Blue Netherworld Universe and the Great Dao Universe thirty thousand years ago.

30,000 years ago, the top sage of the Qing Netherworld universe challenged the top sage of the Great Dao Universe, with the hundred sections of the city wall as the boundary, and the land within a radius of thousands of miles under the jurisdiction of the hundred sections of the city wall was laid out in an isolation formation, and the monks who had just been led to the Tianmu battlefield would appear in this formation.

Whether it is a cultivator of the Qing Netherworld Universe or a cultivator of the Great Dao Universe, if you want to leave the isolation formation, there are three ways, one is to resist the pressure of the Supreme Realm and break through the isolation barrier like Ye Fei.

The second is to kill a cultivator from the opposing universe, then the coercion and isolation barrier will automatically become ineffective against it, and you can return to your own camp.

The third is to survive in the Isolation Array for three months, and after three months, the Isolation Barrier will also be ineffective for it, and you can return to your own camp.

Whether it is a cultivator from the Qing Netherworld Universe or the Great Dao Universe, after being brought here, their eyes are blackened, and they don't know any situation, and only if they succeed in killing a cultivator from the opposing universe will they know the reason.

If you know why, if you don't want to leave right away, you can stay in the Isolation Array for three months before leaving.

Without the ability to break through the barrier and kill the cultivators of the opposing universe, it is impossible for the cultivators to know anything about the Isolation Array.

The top sages of the two universes all swear by Dao hearts, and they will not inform anyone of the situation in advance, because the consequences of breaking the oath are Dao Heart Cultivators, and no one will let a top Great Sage Dao Heart Cultivator for the sake of those cultivators who have just been led to the Heavenly Curtain Battlefield.

There were only so many records on the jade slip, Ye Fei looked at Wu Ning after putting down the jade slip and asked, "Martial arts friend, I am in the city now, can I go back?"

"Naturally, from the time Ye Daoyou came to the Advent Sky Battlefield, you can stay in the Isolation Great Array for three months. Wu Ning smiled at Ye Fei and said, "However, before Ye Daoyou's friends have not killed the cultivators of the Qing Netherworld Universe, Ye Daoyou can't tell them about the jade slip in advance, otherwise, whether it is Ye Daoyou or those who know the situation in advance, they will be immediately teleported out of the Isolation Array, which is the rule of the Great Array." ”

"Isn't it just right to be teleported out of the Isolation Array?" Ye Fei looked at Wu Ning with doubts.

"What if you are teleported to the territory of the Qing Netherworld Universe?" Wu Ning did not have the slightest smile on his face, but stared at Ye Fei with extreme seriousness: "For the sake of Ye Daoyou and your friends, you must keep your mouth shut. ”

Ye Fei suddenly understood that after violating the rules, he would be teleported out of the isolation array, which meant being teleported to the opponent's territory, which would inevitably be a lifeless end, and immediately hugged his fist at Wu Ning again and thanked: "Thank you for the reminder." ”

"You're welcome, it's my honor that a super genius like Ye Daoyou can appear in the area where I am stationed. Wu Ning smiled and clenched his fists in return, "Ye Daoyou, is there anything else you want to ask?" If not, go and meet your friends as soon as possible." ”

Ye Fei got up, hugged his fists again and thanked him before leaving.

"Ye Daoyou, Wu is here watching Ye Daoyou kill in all directions. Wu Ning laughed and patted Ye Fei's shoulder.

"The little brother will not disappoint the martial arts friends. Ye Fei smiled with Wu Ning, turned around and left the side hall, and Wu Ning came out behind him.

"Martial arts friend, am I still jumping like this?" Ye Fei walked to the edge of the city, standing at the head of the city, his divine sense tried to probe outward, and found that at the head of the city, his divine sense could probe the situation under the city wall at will, without any interference, Ye Fei could clearly perceive the situation of Ye Xiaomu, Qin Xin and others.
