Wei Feiwen swallowed his saliva and stopped talking. He just felt that the status of the two handsome, young people with unique temperaments in front of him had suddenly risen countless levels.

He then took the two of them to the roof of the hotel and left by helicopter.

"The mail ghost is currently only spreading to our northwest. Four thousand and ninety-six people were killed yesterday." Wei Feiwen couldn't help but shudder when he mentioned this number.

Shen Yi glanced at him.

Chu Lin used to be the person responsible for liaison with them, but in addition to being a liaison officer, Chu Lin's own status and ability were also very high.

In this regard, the Wei Feiwen in front of him is far inferior.

"Two to the twelfth power." Mo Yan also sighed softly, "Tomorrow there will be more than 8,000 people."

This is the scariest thing about this mail ghost.

The number of killings is completely an exponential power function.

At this rate, if there is no solution, all of humanity will be extinct in a dozen days.

This is also the reason why Mo Yan was so anxious to apply for help.

Shen Yi remained completely silent along the way.

It wasn't until four hours later that everyone arrived at their destination.

This is an ordinary apartment building. It has now been completely isolated. All the people have been relocated, leaving only one family. The male owner of this family, a man named Zhu Zishi, is the reason why Shen Yi and the others were brought here.

"Male, 34 years old, second-level criminal police officer, named Zhu Zishi, with a pair of twin daughters." Wei Feiwen briefly introduced the man's situation, "Seven hours and forty minutes ago, he saw this letter at the head of his bed. After identification, it was determined that it was sent by a special ghost named the Mail Ghost. According to the law, he can live for another sixteen hours and twenty minutes."

It took exactly one hour from the time he received the letter to the time he died.

The reason why I am so sure is that the ghosts in this world kill people in a certain way.

Shen Yi glanced at the man sitting on the sofa, holding hands tightly with his wife.

He is tall and handsome, with a natural and upright temperament between his brows. Even though he is pale and haggard now, he still remains calm.

This is probably why Wei Feiwen brought them here.

There are 8,000 victims in this round. If we want to find a breakthrough, it would be most appropriate to find a trustworthy person with strong psychological quality.

Shen Yi looked at the photo hanging on the wall again. There was a pair of cute twins who looked about ten years old.

"Didn't you tell your daughter?" Shen Yi asked the first question after coming here.

"They are still young." Zhu Zishi's voice was a little hoarse, "They can't bear it."

"Maybe." Shen Yi's expression did not change. He just said calmly, "But you should know that the mail ghost will spread along the personal relationships of the victims, first to blood relatives, then to distant relatives, then to friends, and finally to strangers. In other words, your daughter can only live for two or three days at most."

This is undoubtedly a cruel and terrifying fact.

It even made Zhu Zishi look painful.

"I don't know." He even answered irrelevantly, his eyes blank, "I don't know what to do."

Obviously, he had thought about this fact. Rather, a large part of his current pain was due to this.

"No." Shen Yi shook his head, "This ghost is actually not strong."

"Not strong?"

In a word, everyone at the scene had their own expression.

Mo Yan acted as if it was a matter of course, Zhu Zishi and Wei Feiwen were stunned, and Zhu Zishi's wife was a little overjoyed, as if she suddenly saw hope.

"Yes, not strong." Shen Yi focused his eyes on the envelope in front of him, "Judging from the concentration of ghost energy, it is only about the fourth level at most."

"Indeed." Mo Yan also interjected, "If it was me who got hit, I wouldn't be afraid at all. But, Chief, this ghost's way of killing people is very strange. It's not killing in the conventional sense, and it has nothing to do with curses, spells, etc. It's more like..."

"Rules." Shen Yi spoke for him, "It's like a god taking action personally. Even if he only uses the power of the fourth level, you can't stop him."

"Yes, that's it!" Mo Yan nodded vigorously.

His strength is level six, but as a savior of the Pan-Human Guardian Association, one cannot judge a person's vision solely based on his strength.

So Mo Yan actually knew a long time ago that the ghost apocalypse in this world was full of anomalies.

It is not simply judged according to extraordinary levels such as "first order, second order".

For example, the mail ghost, which is the biggest threat at the moment.

It doesn't seem to be strong, but it can spread from one to two, and from two to four, as if there is no end, and it has never even revealed its true form. This is simply not something that the so-called extraordinary class can explain.

Even a sixth-rank expert in the Pan-Humanistic Guardian Association would find it difficult to use this exponentially spreading curse.

The conversation between Shen Yi and Mo Yan sounded quite confusing to the others.

What ghost energy, gods, fourth level, rules... I don't understand at all.

Wei Feiwen pricked up his ears, as if he wanted to understand, but he didn't dare to ask and could only remember every word.

Ever since the appearance of ghosts, the materialistic concepts of the entire world have completely collapsed. All of humanity, especially those who hold power and wealth, have felt a panic far beyond that of ordinary people.

Everything they have, or everything that all mankind has, is meaningless in front of ghosts.

Just like facing death, all beings are equal.

And Mo Yan, the only one who appeared before them, was able to understand that strange and dangerous unfamiliar world.

Now, there are two more powerful ones! Wei Feiwen didn't dare to ask rashly, but Zhu Zishi's wife couldn't care less.

The fact that he didn't kneel down and cry and beg was a testament to his strong personal qualities.

She suppressed her inner anxiety and pain, and asked carefully: "Sir, is it easy or difficult to stop this ghost?"

"For someone who has reached my level, it's very simple." Shen Yi reached out and picked up the paper on the table. "The ghost itself is not strong. It just relies on the rules to kill people. So as long as the rules are modified, it will be easy to deal with this ghost."
