28.

"It is said that practice is the only criterion for testing the truth. I just heard you say so much and feel a little dizzy. I think it's better to practice it immediately, it's intuitive." Wang Shuo said.

Nika nodded and said, "Okay, let's go back to the store and I'll teach you how to start selling regret medicine."

After saying that, Nika bent down and took out a white and gray stone the size of a palm from under her skirt.

Then Nika held the stone in both hands and rubbed it, and a teleportation light ball reflected out of the stone and floated in mid-air.

"Damn, this must be Hearthstone!" Wang Shuo said with his eyes shining.

He missed those green years so much that in a certain MMORPG game, he had to rub the hearthstone and open the door to go home every day.

"No, the store manager, this is called the teleportation stone." Nika denied.

"What kind of teleportation stone? There is no feeling at all, so I have to call him Hearthstone!" Wang Shuo cut off the railway.

"Well... Okay, store manager, you're happy. You can call me whatever you want." Nika didn't insist and continued, "Then we will go back to the store first. If you want to sell regret medicine, you have to be in the store."

Wang Shuo immediately said, "You have to go back to the store. I thought I was selling it on the street!"

Nika's head tilted even more and looked almost overturned: "Shopkeeper, we are not unlicensed vendors, why are we selling on the roadside?"

"Isn't this misled by your director? He caught the strong men on the street like this." Wang Shuo complained.

"The director has a different strength. He has strong abilities and can find the most suitable person in the vast crowd without any equipment. But we are different, we still have to rely on some screening equipment in the store to help us find the right customers."

After Nika finished speaking, she got into the teleportation light ball.

Wang Shuo shrugged and followed.

The next second, Wang Shuo walked out of the teleportation light ball and found himself coming to the hall that looked a bit mysterious in science fiction.

That is, Wang Shuo’s branch, where the branch No. 108 of the company is located.

There are some sci-fi-looking instruments and devices placed around this hall, which makes the entire hall look particularly sci-fi-mysterious. Some strange lights are flashing everywhere, and it looks a bit dreamy.

Then Nika came to the instrument placed on the far left and started operating on the console above.

"Shopkeeper, this is a regret filter, which can be used to monitor the regrets of everyone on this planet, and can be filtered according to the conditions set by the store manager to facilitate you to find the right customers."

Wang Shuo leaned over and looked at it, only seeing Nika operating on some windows that he couldn't understand. He couldn't help but say, "This looks a bit complicated. Can you change this window interface to an operation interface that I can understand?"

Nika patted her tilted forehead and said, "Oh, I forgot, store manager, you are not used to the three-dimensional multi-dimensional operation of the Empire. Wait, I'll change the UI interface now."

After Nika operated the instrument twice, the three-dimensional operation interface on the instrument became the familiar flat light screen UI interface of Wang Shuo.

"Okay, I'll give you a set of V110 million versions of the fool-style control plug-in for the store manager. It will definitely allow you to easily control these instruments!"

Wang Shuo just wants to know who is so bored, he will update a set of fool-style control plug-ins with 110 million versions!

Well, the thinking of high-tech stars cannot be speculated based on the thinking of earthlings.

While complaining in his heart, Wang Shuo took over the operation of this regret filter from Nika.

It is worthy of being a fool-style control plug-in. Under Nika's teaching, Wang Shuo was able to operate it proficiently in a short while.

In short, this regret filter can list all the regrets of everyone on the entire earth, and then filter them according to the conditions set by the operator.

The so-called degree of regret is the degree of regret of a person's past.

"Yeah, then I'll try to set some conditional filtering first."

If conditions are not set, I regret that the screen of the screen will list all 9 billion people on the earth, and I can’t finish reading it even if I see death.

"Set filter criteria 1: Only things you regret are within the 1-day time frame."

Wang Shuo first set this condition.

Because I only have one 1-day regret medicine in my hand now, I can only let those who regret within 1 day go back to the past.

If the things he regrets for more than one day, he will be helpless now.

After setting this screening condition, 9 billion people suddenly lost 95%.

Only 5% of the people remain, and there are almost more than 400 million.

In other words, there are more than 400 million people on Earth who have encountered things that they regret in the past day.

"Well, this is much less, so let's continue to filter. Set the location range, just the X area where I am now."

So Wang Shuo sets filtering conditions 2: within the scope of City X.

This time, more than 400 million people suddenly dropped sharply to 367.

"Well, that is to say, in City X, 367 people encountered something that made them regret yesterday.

"It's still a little bit too much, so let these 367 people sort according to the level of regret."

Wang Shuo operated it again on the light screen and set up a sort, allowing these 367 people to sort from high to low according to their regret.

After sorting, you can see that the 367 people have the highest regrets, with 36 points of regret, while the 1 point of regret is the lowest.

Seeing that Wang Shuo’s concept of regret is not very clear, Nika explained just rightly: “There are two main factors that affect regret.

“One is different from person to person, and the other is affected by time.

"It is easier to understand different people. Some people are prone to regret, while others are more open-minded. The same thing happens to different people, and the degree of regret is different.

“Secondly, regret will change over time.

"For example, some people, as time goes by, because of some opportunities, will relieve the regrets in the past, and their regrets will decrease or even disappear.

"But more people, as time goes by, regrets will slowly ferment and become more regretful, and then the degree of regret will increase exponentially.

"So the people you selected were not very high because the things you regret happened yesterday.

"If you relax the screening time, you can see a lot of regrets that are very high, hundreds of regrets that may be encountered."
