"That's right, this whole school is a ghost domain, and it's rare to see such a small ghost domain......" Agen said with a solemn face.

"Why do you say that?" The rest of my life was a little confused.

"The larger the range, the weaker the control over the ghost domain, and vice versa." There was a cautious expression on Agen's face: "There are generally only two possibilities for doing this......

"What is it?!" Ever since Agen spoke of the Ghost Realm, he had stopped for the rest of his life, and he was clearly aware of the seriousness of the problem.

Agen looked left and right, as if trying to find out who was behind the ghost domain, but found nothing.

He frowned and said, "There are two possibilities, one is that he is in a very weak state at this time, similar to me before, and the other is that there is something very important here for him, to prevent intruders." ”

"If it's the first type, it doesn't matter, but if it's the second type, then we have to be careful, everyone who walks into his ghost domain will be treated as an intruder......"

Yu Sheng scanned around and didn't find anything unusual, but since entering this school, it was as if he had been cut off from the outside world, losing all the sounds and breath outside the school.

"And what kind of person do you think he belongs to?" Yu Sheng looked at Agen with a solemn expression.

Agen didn't answer immediately, and black gas began to gradually erupt from his body, which soon enveloped the entire Dongcheng No. 1 Elementary School.

When he made this move, Uncle Zhang subconsciously took a few steps back, and the black cat on Yu Sheng's shoulders obviously became nervous, his whole body shrunk into a ball, and the claws on his feet grabbed his shoulders tightly.

"Don't be nervous! Agen is our friend and he will not hurt us. Yu Sheng touched the black cat on his shoulder, and looked back at Uncle Zhang behind him.

The corpse qi enveloped the entire school, and this time there was no pungent smell coming out, but it gave Yu Sheng some sense of security, but he didn't know what would happen if the two ghost domains overlapped.

"This guy's ghost domain is airtight...... It's not like a weak time at all, and we're afraid we'll have to be careful. Agen whispered.

His release of the Ghost Domain was just a temptation, but it was like a mud cow entering the sea, and he was completely unable to invade the opponent's Ghost Domain, let alone find the opponent's location.

"Listen to you say that, there are still strong and weak in the ghost domain?" Yu Sheng's eyes flickered.

Agen said in a deep voice: "There are strong and weak ghosts, of course there are ghost domains, and powerful ghost domains can invade weak ghost domains, or even completely control them. ”

"Hiss......" Yu Sheng gasped.

This information is precious to him, even to all mankind, after all, the knowledge of the major organizations about the ghost domain is only scratching the surface, and there is no detailed record in the association's materials.

People's understanding of ghosts is still in the film and television and the previous impression, terrifying, bloodthirsty, cruel, blue-faced and fanged...... But that's not the case, at least not for the rest of my life.

"Agen, isn't this guy even better than you?" Yu Sheng was silent for a moment and asked.

"I can't tell, I was injured in the battle with the Red Umbrella, and I'm not in my prime......" Agen frowned, his black-blue body had countless holes carved out by water droplets, mingled with dense pinholes.

However, just as he finished speaking, there was a loud noise in the school, like the sound of a wall collapsing and smashing on the ground.

Yu Sheng and the others immediately tensed their nerves, and they didn't come to the air, maybe this was the other party's warning to let them get out of here.

However, at this moment, a red figure ran out from the depths of the school, and a trace of surprise flashed on his face when he saw Yu Sheng, but then he quickly calmed down and rushed towards this side.

Agen immediately stopped in front of Yu Sheng, and was about to make a move but was stopped by Yu Sheng: "Don't do it, she's my sister ......"

Jiang Hong took a light step and soon came to Yu Sheng's side, but before he could speak, he grabbed his hand and ran towards the school gate.

Uncle Zhang and Agen were stunned and immediately chased after them.

"Meow ......" the black cat let out an anxious cry, it was very afraid of Jiang Hong, but it didn't dare to move.

"Red! What's going on? What are you doing here? Yu Sheng gasped.

But at this time, Jiang Hong seemed to be very anxious and did not answer him, and everyone came to the door of Dongcheng No. 1 Primary School, but at this time, the gate of the school was blocked by a wall that had never been seen before.

A human face gradually appeared on the wall, staring at Jiang Hong with a vicious face, its gaze locked on the exquisite box in her hand.

Yu Sheng didn't pay attention before, and only then did he find the box in Jiang Hong's other hand.

"Is this what you're looking for...... Did you find it? ”

"Well......" Jiang Hong nodded, and said with an anxious face: "But now is not the time to talk about this, this guy is very powerful, let's escape from here first!" ”

The wall with the human face suddenly twisted, and it opened a bloody mouth and bit down on Yu Sheng and the others.

Jiang Hong and Yu Sheng were not ordinary people, and Agen and Uncle Zhang reacted faster and immediately dodged this sudden attack.

Staring at the vicious face on the wall, Yu Sheng's eyes flickered: "This guy ......"

This guy is at least an A-class ghost, and obviously can't communicate, he's more like a collection of school grudges, and if you look closely, you'll see that there are countless looming faces on the wall, and those faces are all students of this school!

"You took its stuff?" Yu Sheng dragged Jiang Hong to run around, and asked her while dodging the attack of the human face.

"This thing was originally left to me by someone else." Jiang Hong shook his head and shook the box in his hand.

Yu Sheng's face sank: "Okay, it's useless to talk about this now, can you deal with this guy?" ”

"I can't do it alone...... Jiang Hong glanced at Agen who was not far away, "But if you add him, it's definitely no problem!" ”

She obviously recognized Agen, who had been in and out of the East City so many times, and she was very familiar with several A-class ghosts here.

"Agen! It's not a way to run all the time, you and my sister shoot together, give that guy some color and see! Yu Sheng's eyes moved slightly, and he shouted at Agen.

After hearing his words, Agen immediately looked over, stayed on Jiang Hong for a few seconds, and then nodded.

The black gas in the sky gradually surged around his body, condensed into a black liquid, and black-green corpse poison flowed from the pinholes on his body, mixed with the black liquid, and rushed towards the wall in front of him.

And after seeing Ah Jean's move, Jiang Hong also stopped, and the blood mist began to escape from her body, instantly turning into a blood-colored giant and rushing towards the human wall.

The rest of his life watched these changes from beginning to end, and his pupils suddenly shrank after those blood mist appeared, a feeling that was very familiar to him, very similar to the bloody world behind the door......
