After the message was sent, Yang Jian looked nervously out of the door.

He only had insight into the killing law of the old man who knocked on the door, and he was not sure if this trick could lure him away.

The killing rule of the ghost old man who knocks on the door is to kill the person who hears the knocking sound, as well as everyone in the ghost domain!

However, there is a problem here.

In addition to Yang Jian, many people also heard the audio of the knock on the door in the post of the doctor called "Caller King" in the forum.

These people are scattered all over the world, and it is impossible for the knockers to kill people all at once.

So who does he kill first and then who he kills?

Devils have no emotion or intelligence, and their behavior follows a certain pattern exactly.

Therefore, Yang Jian boldly guessed that the order of this knocker killing people was likely to be related to the number of people!

The number of people in this includes two points.

One is the number of people who heard the knock on the door in the same place.

The second is the number of people around the person who was cursed by the knock on the door.

Yang Jian was in the school, and there were thousands of people here, so the knocker found him the next day.

After Yang Jian found the old man knocking on the door, he has been thinking about a question.

If there are a lot of people cursed by the knock in one place at the same time, and there are many people nearby, will the knocker be lured away?

Time is pressing, Yang Jian has no time to verify, so he can only gamble!

He bet that the killing pattern of knockers is related to the number of people, that those scammers can receive the message, that the scammer will open the audio file after receiving the message, and that there are more than two people on the scammer's side who hear the knock!

This gamble is very risky, as long as there is a little accident in the middle, Zhou Zheng must face the terrifying and inexplicable supernatural power of the ghost old man at the cost of the resurrection of the ghost!

When the time comes, Zhou Zheng will die, and Yang Jian will have to follow the trajectory in his dream to walk on the path of the ghost rider again in order to survive.

This is what Yang Jian does not want to see.

He had been a ghost rider in his dreams for several years, tired of being insensitive, living like the walking dead.

Unless it comes to the point of last resort, Yang Jian doesn't want to repeat the mistakes of the past!

The ghost realm is still invading, and the classroom is eroded by the dark supernatural power, becoming decayed and dilapidated, and at the same time emitting a disgusting stench.

"Failed?"

Zhou Zheng frowned.

Behind him, the blue-gray ghost domain belonging to the starving ghost reappeared.

Although Yang Jian reminded Zhou Zheng not to let him continue to use the supernatural power, he was the person in charge of Dachang City, and it was impossible for him to be indifferent to watch so many children die in front of him.

"Looks like we're going to prepare for the worst!"

Zhou Zhengyi beckoned and directly brought Yang Jian to his side with the ghost domain.

He took out a satellite phone that looked like a big brother from his pocket, took out the piece of vellum paper, and then put the two things in Yang Jian's hand with a solemn expression.

"I'll drag that ghost in a while, you find a chance to take your classmates out!"

"If, I mean, if you can't do anything and get out on your own, you must hand these two things over to the Ghost Rider Headquarters!"

"Don't run around after you go out, just hold your phone, and the people at the headquarters will be looking for you soon!"

"Remember, this piece of human skin paper is extremely important to the headquarters, and it must be handed over in good condition!"

Although Zhou Zheng wanted to save all the students, he also knew that it was impossible.

Ordinary people are too vulnerable in front of ghosts with supernatural powers.

Even if Zhou Zheng dragged the terrifying old man outside the door at the risk of reviving the ghost, it was already a blessing to be able to save half of the students in the end!

And among these students, Yang Jian, who predicted the future from the human skin, undoubtedly has the best chance of survival!

Thinking of this, Zhou Zheng turned his head to look at the boy named Fang Jing in the classroom.

Fang Jing looked at the constantly invading ghost realm outside the door, and his face was extremely frightened.

However, it has reached such a critical situation, Fang Jing's eyes are still staring at his classmate Yang Jian resentfully, as if Yang Jian pierced the secret of someone's skin paper in his hand is the same as if he had a revenge for killing his father!

"Although that student has also seen part of the future, his mind has been affected by the supernatural power of the human skin paper, and it is useless, and I hope it will still be placed on this student named Yang Jian."

Zhou Zheng made up his mind that once he couldn't suppress the powerful ghosts outside the door, he would directly use the ghost domain to send Yang Jian away.

Everyone else can die, but Yang Jian with the human skin paper can't!

Zhou Zheng has a lot of experience in dealing with supernatural events, and after listening to Yang Jian talk about the role of the human skin paper, he immediately became keenly aware of the value of this supernatural item to the headquarters.

In the hands of ordinary ghost riders, human skin paper is just an ordinary supernatural item.

But when it comes to the headquarters, this thing is a life-saving treasure!

Therefore, no matter what the price is, Zhou Zheng must also send the human skin paper to the headquarters!

The ghost domain outside the door is constantly eroding into the classroom, and Zhou Zheng's ghost domain has begun to be suppressed.

"Can't wait any longer!"

A glint flashed in Zhou Zheng's scarlet eyes.

The horror of the ghost outside the door far exceeded Zhou Zheng's expectations.

If Zhou Zheng is in good shape, he can barely support it.

But he is now on the verge of supernatural revival, and the ghost domain of the hungry ghost can no longer suppress the fierce ghosts outside the door.

He must take advantage of the fact that the ghost domain can still be used to send Yang Jian away, otherwise when the ghost domain outside the door is suppressed, no one will be able to leave.

Yang Jian's eyes have been staring at the old man knocking on the door all the time!

Just as Zhou Zheng was about to use the ghost domain to send him away, Yang Jian suddenly shouted, "Wait a minute! ”

Zhou Zheng was stunned for a moment, and then looked out of the door suddenly.

The pitch-black ghost realm suddenly receded like a tide, and the suppressed lights in the classroom were regaining their light.

The stiff old man in the hallway is gone!

"Are you gone......"

While Zhou Zheng breathed a long sigh of relief, his eyes turned to the handsome young man on the side.

"How did he do it?"

Meanwhile.

Metropolitan Base, 13th basement, cloning experiment center.

"Bang, bang......"

An eerie knock on the door resounded throughout the lab.

Hundreds of researchers listened to the knock on the door, their hands tapping quickly on the keyboard in front of the computer screen.

They are analyzing the meaning of this knock on the door, hoping to use it as an opportunity to analyze the mystery of alien life!

Dr. Sophia's eyes lit up, staring at the big screen in the control center.

"It's not close! I can almost decipher the meaning of this voice. ”

The assistant on the side listened to the strange voice echoing in the laboratory, and said hesitantly, "Doctor, I think this is a very ordinary knock on the door......

"Impossible! When pigs fly! ”

Dr. Sophia interrupted her mercilessly: "This is the first time that aliens have made a sound in more than twenty years, how can it be as simple as a knock on the door?" ”

After speaking, she watched the progress of the analysis continue to advance, and her face showed a look of hope and expectation.

"I have a hunch that this voice contains a big secret! It's sure to be a big surprise for us! ”
