The end of this world is the most confusing doomsday Shen Yi has ever experienced.

Although we have also come up with a countermeasure like the Ghost Rider.

But he had no idea how the evil ghost appeared or what it would look like.

Although it is not impossible, after reaching a certain peak, it will slowly disappear.

After all, if they had not appeared, the number of evil spirits that appeared during this period of time alone would be enough to destroy the entire world - evil spirits that eat people would become stronger rapidly.

But only the evil spirits in the Tang Dynasty are decreasing?

This is very interesting.

"Are you sure that the number of evil spirits born in the Tang Dynasty is really decreasing?" Shen Yi emphasized the word "born".

"I can't be sure." Ding Xiang shook her head gently. "My supervision of this world is based on firefly detectors and high-altitude satellites. This is a technological means. I can only detect evil spirits when they begin to show signs, or at least start to scare people."

"So, do you think it has something to do with the control during this period?" Shen Yi asked again.

During this period, the entire Tang Dynasty no longer dared to kill people at will.

First of all, everyone knows that people may turn into evil ghosts after death.

Secondly, now that the Immortal King has appeared in the world, there are gods above our heads, and no one dares to do evil easily.

Theoretically, this should have a certain influence on curbing the birth of evil spirits.

"It may be related, but the effect of control will not reach this extent." Ding Xiang shook her head again, her cold eyes looked a little solemn, "Captain, do you remember the second evil ghost we dealt with?"

"That old lady?" Shen Yi naturally would not forget her.

"She died accidentally, but because she was so unwilling to see her son die without an heir, she turned into a demon after death." Ding Xiang said, "From this, it can be seen that unwillingness can also turn into a demon. And judging from the subsequent trend, the probability of turning into a demon after death is increasing. What's more, the news of the immortal and the catastrophe spread throughout the Tang Dynasty two months ago, and in these two months, the number of demons has continued to rise."

Shen Yi understood what Ding Xiang meant.

Although in the beginning, only those who are extremely unwilling or are cruelly tortured by others can turn into evil spirits.

However, in the near future, people who die naturally with only a few regrets, or even no regrets at all, will turn into evil spirits.

In other words, although people's subjective avoidance of killing has a positive effect, it is not enough to curb the rising trend of the number of evil spirits.

"If the birth of evil ghosts has not decreased, does it mean that after the evil ghosts are born, they do not cause any disturbance and disappear directly, so you cannot find them." Shen Yi added.

"Yes, that's the only possibility." Dingxiang replied.

"This is interesting." Shen Yi showed an interested expression.

After this period of time, the characteristics of evil spirits have become very clear. After birth, although they have a certain degree of intelligence, they are not smart.

It just instinctively creates fear and sucks qi and blood.

Once they become powerful, they will kill and suck blood without hesitation. To some extent, they are completely different creatures from humans.

Theoretically, as long as such evil spirits begin to interfere with reality, scare or harm people, they will not be able to escape the monitoring of the firefly detector.

After thinking for a while, Shen Yi came up with an idea.

"You continue to monitor those ghosts that jump out to harm people. I will do the hard work and use a crude method to monitor the birth of ghosts in some cities to see if I can find anything."

"Yes." Ding Xiang pursed her lips.

When ghosts were first created, they were invisible and traceless, and could not be found with just a firefly detector.

And observing with the power of the mysterious side, her current strength can only monitor the entire Chang'an City at most.

Still not strong enough.

This was probably the first time that Dingxiang felt an urgent need to increase her strength.

And Shen Yi still stood in his position on the deck, with a halo of magic surging in his eyes, forming an intricate pattern.

Since fate cannot be predicted, he can only use a stupid method.

Luoyang, Yangzhou, Yizhou, Jingzhou, and Jinling.

Five cities.

In these cities, people die every day.

Keep staring.

Let’s see if the number of evil spirits born is really decreasing, or if there is some other reason.

This is of course a stupid way.

A day passed.

"During this day, a total of 472 people died in the five cities. The souls of seven people have begun to condense into the initial ghosts." Shen Yi said.

"Seven people?" Ding Xiang's eyes narrowed slightly. "This is different from the probability I observed. Currently, the number of instant evil ghosts born in the entire Tang Dynasty accounts for one percent of the number of deaths. However, it may also be a sample bias."

"One percent? That's about five people." Shen Yi nodded to show that he understood.

One percent is actually not a small amount.

Remember, this is one percent of all deaths.

Including natural deaths, deaths from illness, premature death, and production accidents, considering the population size and average age of this era, hundreds of thousands of evil ghosts will be born in less than forty or fifty years. This is assuming that the probability remains unchanged and the evil ghosts are controlled from harming people.

If they don't come.

This world will surely become a ghost town with no living creatures.

Shen Yi continued to stare at the five cities, especially the seven ghosts that were born.

By now, almost every important city in the entire Tang Dynasty has at least three ghost riders stationed there for a long time. After all, once an evil ghost appears in a city, it will soon cause serious consequences if it is not strangled in the cradle as soon as possible.

There are also three people stationed in Yizhou City.

The leader among them was Cui Ren.

He was also considered one of the first ghost controllers in the Tang Dynasty. He initially followed Master Gu and killed ghosts for more than two months. The ghosts he controlled had reached the second level.

That's why he can rule a big city.

On weekdays, in addition to receiving information related to ghosts and going to check them out, they also have to record the deaths in the city every day.

Because each of them has the potential to turn into an evil spirit.

Of course, these matters are also handled by other people, and they will only be informed in special circumstances.

At this time in Yizhou City, there were two newly born ghosts, one of which had already started to become active after nightfall.

Due to insufficient resentment, it was not very strong when it was first born and could only intimidate others to absorb their qi and blood.

With a scream at night, the news quickly reached Cui Ren.

"I will go there myself on this matter, and you two continue to stay here." Black mist emerged from Cui Ren's body and he ran straight towards the place where the evil ghost was suspected to have appeared.
