Because it was getting dark, the monk named Song Mingqing went to the neighborhood to find some firewood and lit a fire.

The light of the fire dispelled the darkness, but only a little fear in the hearts of the people.

At this time, it had only been an hour or two since the last appearance of the ghost, and it was not yet time for the ghost to appear.

But the shadow of that ghost hung firmly over everyone's heart, and many of those present had horror on their faces.

Ye Mingke didn't have fear on his face, he just lowered his head, and while listening to Li Guifan's narration, he wrote something on the ground with a branch.

The first line of words is: Black Curtain, Humanoid Thunder, Possession

These are the three forms in which ghosts exist.

The second line of words is: rebirth, possession, thunder and fire

This is the power of ghosts.

The third line is much larger than the first two, and it is: Don't let the ghost escape!

This is a taboo in the face of ghosts.

He has a strong mental arithmetic and memory, but he has the habit of typing drafts to sort out his thoughts. This was when he was learning Tianyan chess, he was fed by Aunt Long with Xiaoshan Gao's scratch paper.

"After returning, the strength of the ghost is beyond the scope of what you can deal with, so how did you escape later?"

Ye Mingke asked, his voice was still very calm, bringing a sense of security to the people around him, and people couldn't help but have some trust in him.

"I used the Spiritual Talisman to kill the ghost who escaped and returned. Jian Jiu on the side said lightly, he may be the only person in the field other than Ye Mingke who does not have much fear and can stay calm.

Of course, not far away, Ying Kui, who was leaning against the shadows under the tree with his sword in his hand, and his face was gloomy and crazy, and he didn't have much fear of ghosts, but he was half-crazy, and he couldn't keep his calm.

"The Enlightenment Talisman is an extremely precious talisman in the sect that bestows on our disciples to save their lives. It doesn't need to be driven by spiritual power, it can be stimulated by hooking the spiritual imprint on it. It's powerful. ”

"Except for Senior Brother Jianjiu, there is only one among us, and only I have one. ”

Perhaps it was Ye Mingke's calm and clear thinking that made Li Guifan have more hope for this strange mortal, and he was very detailed when he told it.

"After Senior Brother Jian Jiu destroyed that ghost with a charm, we were afraid that the ghost would appear again. Edgeworth flew for a day, but even though we were far away from the area where we had encountered the ghost before, the ghost reappeared in front of us last night. ”

"The ghost appeared for the fourth time, possessed and killed one of us, and was destroyed by us. ”

Ye Mingke remembered the few bright sword lights he saw in the sky last night, maybe they were these people in front of him.

Unfortunately, although he had been alert last night, he ended up meeting these monks and found himself in an extremely dangerous situation.

"After that time, like you, I began to try to summarize the behavior of ghosts from their behavior. ”

Jian Jiu opened his mouth at this time, he glanced at the words written on the ground by Ye Mingke, and knew that the way the person in front of him solved the problem was very close to his own thinking.

He looked at Ye Mingke, and there was a bright light in his indifferent pupils.

"I found a common denominator from the demon's possession and attack on people, that is, the target of each demon's possession attack is the weakest person among us. So I came up with a conjecture that the demon possessed the weakest one of our group. ”

Li Guifan continued Jian Jiu's words.

"Senior Brother Jianjiu's conjecture was verified when the Dawn Ghost appeared today. The ghost appeared for the fifth time and possessed one of our weakest disciples. Unfortunately, even if we were prepared, we still couldn't save him. ”

"However, Senior Brother Jian Jiu set up a secret method on that junior brother in advance, and intercepted a wisp of pure aura from the ghost. ”

"Therefore, Senior Brother Jianjiu's Qiming Sword can now warn of the appearance of ghosts in advance. ”

"And you were all present when the demon appeared for the sixth time, so I don't need to repeat it. ”

Ye Mingke thoughtfully raised his head to look at the delicate little sword that was intimately shuttling between Jian Jiu's long hair, and then closed his eyes.

Today, the scenes that were imprinted in his mind when the ghost appeared resurfaced.

The white-clothed monk who swooped down and grabbed Fang Wu's arm with a hideous face, Jian Jiu's delicate little sword, Jian Jiu's ghost slaying sword array, the possession of ghosts, the breath of ghosts, and the escape of ghosts.

Everything he had personally felt and the information he had just heard Jian Jiu and Li Guifan retell corroborate in his mind.

He opened his eyes and spoke.

"First, the weakest law of ghost possession has been verified at least four times, and it is basically credible, including Fang Wu, and he should also be the weakest of us in terms of physique. ”

Fang Wu, who was lowering his head and pressing his freshly bandaged arm, heard his name, and subconsciously raised his slender face.

His elongated face was blue-black, deeply sunken, like a mortal drunkard, and his eyes were cloudy and dull, and he could only see the look of horror

There were also a few people in the field who turned their gaze to Fang Wu's face. This alcoholic, timid drunkard, although younger than Liu Laohan and older than the underage Ye Mingke and the bamboo pole, is indeed likely to be the person with the worst physique in the field.

He saw the stunned gazes of everyone, and after a while finally reacted, his mouth opened wide, and the look of horror in his pupils almost overflowed.

"What the hell...... Look for me next time?"

He trembled, his body so weak that he could barely sit on the ground, and he was about to fall down.

"Quiet. If you're too scared to think and cope. It's all in the hands of the people around you who can deal with it, don't hold back. ”

Ye Mingke's words were interrupted, and he turned his head to look at Fang Wu with a serious and cold expression.

But his words were obviously useless, and Song Mingqing, who was still hanging, patted the shoulder of this mortal who was about to pee, and looked at him coldly.

It was the great fear brought by the immortal in Fang Wu's eyes that made him shut up.

"The weakest theorem needs to be added that ghosts only appear preferentially next to the weakest person. If the ghost fails in the first attack, and there is someone next to him who can successfully possess it, the demon will also attack that person. ”

"That's what it's like to be possessed by demons today. ”

After Ye Mingke finished speaking, he wrote a new two lines on the beach next to the fire.

"Possession success is irreversible. ”

"Demon-possessed people attack the weakest first. ”

Then, he started another line and demarcated an interval by asking Li Guifan about the specific time when the ghost appeared.

The shortest interval between the appearance of ghosts is four hours, and the longest is seven hours.

This interval excludes the time when the ghost returns after escaping for more than a day, and only counts the time it takes for the ghost to be reborn after it is destroyed.

Finally, there is the strength of the ghost.

Ye Mingke raised his head, looked at Jian Jiu, who was sitting quietly by the fire, and asked.

"If the strength of the ghosts you met for the first time is divided into one, then how many ghosts did you meet later?"

His question was a little jumpy and abrupt, Li Guifan and the others didn't react, but Jian Jiu stretched out his hand and used the spirit sword to write seven numbers directly on the beach in front of Ye Mingke.

One, seven, nine, seventy-seven, twenty, twenty-seven, thirty-nine

Ye Mingke looked at the line of numbers and fell into deep thought, frowning, and the branch in his hand was writing something in the clearing.

"What is this?" Song Mingqing asked curiously, looking at the number that could be said to have no pattern at all.

No one answered him, because the two people who could answer him were looking at the numbers on the ground.

"You want to use the algorithm to deduce the law of the speed at which the ghost becomes stronger and the time it appears, and find the starting number that causes the ghost to appear and the variables that affect the strength of the ghost and the time interval between its appearance. ”

Jian Jiu looked at Ye Mingke's deduction on the ground.

"Your algorithm is correct, but I've calculated it before, and none of the models match. ”

"The ghost's behavior seems to be basically random. ”

Ye Mingke did not respond to him, but changed another open space and began to continue the deduction.

"What kind of algorithm is this? No, you have changed seven algorithms, and there is a basic algorithm that I haven't seen before?" Jian Jiu looked at Ye Mingke's deduction, his eyes shining with inspiration, and he was a little surprised.

The number written down by Jian Jiu is to use the strength of the ghost when it first appeared as a basic unit, and use this basic unit to roughly quantify the strength of the ghost that appears each time, and the abruptly increased number in the middle is the strength of the ghost after escaping and returning.

Ye Mingke used these numbers to try to build a model with other factors, but as Jian Jiu said, these numbers seemed to have no pattern at all.

"Not time, at least not entirely. Otherwise, it should be gradual, even if it is a leap growth, then the rate of increase should be faster and faster, so it is not in line. ”

"It's not a location. ”

"It's not about the climate. Climate, is it all foggy weather?"

"Or how long the battle lasts?"

"No, it should be consumption, every time you kill that ghost, it will consume more energy than the energy that the ghost has, so it will keep growing. ”

"But that's not right, the biggest consumption should be to destroy the ghost who escaped and returned, but the energy of the ghost that appeared the second time was far less than seventy-seven, only twenty. ”

Ye Mingke didn't answer Jian Jiu's question, but continued to write and draw while whispering alone, Jian Jiu seemed to have been triggered by something, and the fingers of his right hand were bent and stretched, and he was also calculating something.

But in the end, both of them reluctantly stopped and looked at each other.

"No, I can't. Ye Mingke stopped the branch and said.

"There is no model, there is no pattern. Jian Jiu also put away his uncertain hand and said.

"You two nerds, after all this time, there is no way, and now two hours have passed. Song Mingyu was the first to be unable to stand these two people who played dumb riddles, and puffed out his mouth and urged.

Ye Mingke looked at Jian Jiu: "If you can't figure it out, you can only rely on luck." Two methods. Luckily, at least no one has to die. ”

"You thought of it too. Jian Jiu also looked at Ye Mingke and said.

"Except for the stupid people who are scared, think of that normal person who can. Ye Mingke threw away the branch in his hand, crossed his hands and stretched out his back behind his head, and said lightly.

"The problem is that most people are inferior to normal people in fear. "Sword Nine Dao.

"What the hell are you two nerds thinking? Song Mingyu on the side listened to it with an itch, and said with his teeth and claws.
