The battle post is the war book.

In this world, if people are dissatisfied with a certain person, they will not fight directly, but first send a battle letter to the other party, and then the two sides will make an appointment with each other, and then have a hard-fought battle.

The war post is acceptable or rejected, and it's fair.

It's a pity that in some special places, the battle post is unfair.

For example, in the Falling Moon Academy, this battle post is very unfair, the Yin and Yang family is a powerful faction, and when they cultivate disciples, they also abide by the law of the jungle.

Just like this battle post, if it is outside the academy, then even if you don't accept it, there is nothing, but in the academy of the Yin and Yang family, there is such a clear rule that when a person receives ten battle posts, he must choose to fight with one of them.

This is a kind of compulsory competition, and the only thing that restricts the opponent is that the spirit book level must be of the same level.

Now that Ye Xuan is the Book of Enlightenment, as long as there are ten Books of Enlightenment who have made a war against Ye Xuan, he must reply to one of them and duel with him within three days.

But if there were nine books of enlightenment and one person from the Book of Advancement to send Ye Xuan a battle post, he would not have to fight.

It's a pity that there are many owners of the Book of Enlightenment in the Falling Moon Academy, so when Xiaohong said that there are a lot of battle posts, it means that Ye Xuan has to go through a battle.

"There is such a rule, shouldn't the academy prohibit fights and brawls, why does the academy of the Yin and Yang family still support this, this is simply ...... It's just ......."

Ye Xuan immediately complained after knowing about the battle post.

"Young Master Xuan, since you can't refuse, then you can only choose to accept it, and Miss and Lord Rainbow are also looking for the weakest person in those battle posts for you. Seeing Ye Xuan's depressed face, Xiaohong hurriedly comforted him.

"Wait, you're looking for the weakest person for me, are you trying to exhaust me?" Ye Xuan, who was depressed, suddenly heard this sentence and hurriedly exclaimed.

"Why did Young Master Xuan say this?"

Xiaohong didn't answer Ye Xuan's question, but asked rhetorically with a puzzled face.

Ye Xuan saw that Xiaohong didn't understand the meaning, and immediately sighed: "The hair is long and the knowledge is short!"

"Young Master Xuan, don't be hypocritical, otherwise I don't mind telling Miss what you just said. Although Xiaohong is from Ye Xuan's side, she is also a little depressed after hearing Ye Xuan's words.

Although she understood that Ye Xuan just wanted to show off her IQ and didn't deliberately look down on women, Xiaohong was also a woman after all, and of course she didn't like to hear such words as long hair and short knowledge.

"Well, for the sake of you still having to follow me in the future, I'll reluctantly explain it to you. Ye Xuan originally wanted to tease Xiaohong, and since Xiaohong was so knowledgeable, he also said the reason why he couldn't choose the weakest person.

"Xiaohong, since the rules of the academy are not allowed to challenge me by the people who have entered the Book of Study, then as long as I defeat the strongest Book of Enlightenment, then no one will challenge me again. But if I always pick the weakest, then the battle posts will be sent one by one. Ye Xuan said.

After he finished speaking, Xiao Hong's eyes became a little confused when he looked at him, obviously shocked by Ye Xuan's novel idea.

In fact, Ye Xuan's idea is not new, but his previous experience is different, so he looks at the problem at a different level.

"Don't be in a daze, let's hurry up, and then choose the strongest person in the Book of Enlightenment together, and then figure out his information, and then outperform him, so that this matter will be considered over. ”

Ye Xuan said as he walked towards Rainbow's residence.

"Wait, where is this?"

It's a pity that just a few steps after Ye Xuan walked out, he found that the scene in front of him was not the scene when he came in, whether it was the road, the flowers and plants on the side, or the passage he left, it was no longer the same as before.

"This ...... What's going on?"

Ye Xuan, who didn't know what was going on, turned his head to look at Xiaohong, waiting for this mobile textbook to give him an explanation.

"Young Master Xuan's hair is also very long, and it seems that his knowledge is a little short. Xiaohong rarely caught Ye Xuan's embarrassed appearance, and hurriedly ridiculed.

Ye Xuan also remembered what she said, and now Ye Xuan's body is not short hair, but a long hair shawl, but it has not yet reached the point where long hair reaches the waist, but it is estimated that it will be there in a few years.

However, after all, he is not a woman, and he is also a little younger than Xiaohong, so his hair is still not as long as Xiaohong.

"Ahem, let's talk about how to get out. Ye Xuan coughed twice deliberately, and then didn't look at Xiaohong, how could he have thought that the report of the present world would come so quickly.

"Young Master Xuan, there is the protection of the Yin and Yang Rotation Array, although it is very simple to go out, but you must remember the direction of Yin and Yang, and you can only go out if you find the right position. Xiaohong no longer Ye Xuan, but took the lead and walked to the other side.

"Wait, since this Yin and Yang Rotation Array is so powerful, how do you know the way, and how do the other students know it?" Ye Xuan couldn't figure it out.

You must know that Xiaohong also entered the Falling Moon Academy with Ye Xuan, and he is very sure that Xiaohong has not been to the Falling Moon Academy before, let alone the branch of the Yin and Yang Family, so it stands to reason that neither of them should know the way out.

"It was Miss Rainbow who told me that although the Yin and Yang Rotation Array is constantly changing, it also has a law, and this law is only known to the disciples of the Yin and Yang family and their entourage. Xiaohong explained.

But Ye Xuan was still a little unclear, so he then asked, "Wait, if the method can be told to outsiders, then isn't there no meaning for this method to exist?"

"No, even if outsiders know the location, they can't get in, because they don't have the unique mark of the Yin and Yang family, and that mark is the most important. As she spoke, Xiaohong summoned her spirit book.

"I see! Orientation is not the most important thing, the most important thing is the imprint!"

After Ye Xuan saw Xiaohong's spirit book, he immediately understood what she meant.

It turned out that Xiaohong's spiritual book cover suddenly had a translucent Yin and Yang Taiji diagram, which was a temporary mark, that is, Xiaohong was temporarily given the right to enter here, and Ye Xuan was a disciple of the Yin and Yang family, so he could enter at any time.

At the same time, Ye Xuan also understood a deeper meaning, that is, this branch is not only used for teaching, but also a safe base.

After all, this is not a safe world, once there is a war or a beast tide or something, then as long as you are a disciple of the Yin and Yang family, or someone who has been given a seal, you can enter here for refuge.
