In the noisy and laughing laboratory, Qu Nanxiu forgot his worries for the time being.

Anyway, the professor said that he didn't have to worry about his life. In this world, there is nothing important except life and death.

Qu Nanxiu remembered a question that could not be ignored: "Professor Luo, what exactly is the topic of your research?"

Professor Luo paused, looked at Qu Nanxiu's eyes meaningfully, and said seriously: "Since you trust me so much, I should also treat me with sincerity." To tell you, the project I studied was - regret medicine. ”

"After-repentance-medicine?"

For a moment, Qu Nanxiu wondered if he was hallucinating again.

He looked down, this time there was no ink-colored robe, he was still in sneakers, and he had not become a butcher.

People often say that there is everything in the world, but there is no regret medicine for sale. Even if you enter the word "regret medicine", there will only be a prompt of "according to relevant laws, regulations and policies, the relevant treasures cannot be displayed".

Is Professor Luo's regret medicine a capsule, a granule, or a pill? Will it have side effects on the body? What effect can it have? Can it turn back time and make the past happen again?

Although Professor Luo is an all-rounder, it is still unlikely that he can turn back the clock.

The professor knew that Qu Nanxiu would definitely have doubts, so he took the initiative to explain: "The reason why human beings regret it is because they feel difficult to let go of what they have not been able to do before, or what they have done wrong, and they are always thinking about it, so they constantly complain and regret. ”

Qu Nanxiu nodded in agreement.

"What has happened has happened, and I can't turn back time. But I thought, is it possible to reduce the pain of regret by interfering with the brain's memory?"

Intervention memory - Qu Nanxiu's eyes lit up! What a fresh and hot idea!

"There's a part of the brain inside called the temporal lobe, and the nerve cells are responsible for recalling events and scenes. If the temporal lobes can be appropriately stimulated, I believe that in the future, it will be possible to even customize hallucinations and memories to reduce the pain caused by memories. Moreover, this technology can be widely used in many fields. ”

Shaking and unwilling to be lonely, he answered: "In the medical field, it can be used for psychological trauma treatment, or hospice care, to reduce the pain caused by remorse, and in the criminal field, it can be linked to criminal psychology, and maybe it can help solve cases......

Qu Nanxiu forgot about those annoying bubbles for a while, and immersed himself in this wonderful and fresh idea.

It's really interesting, on the ground, at least 30 years behind reality, but under the ground, it is dozens or even hundreds of years ahead of reality!

I fantasize that one day, a special counter will appear in the corner of the supermarket, and the large and small bottles on the container are only marked with the words "regret medicine". So tens of thousands of people lined up day and night, much more spectacular than the crazy queue, and crowded at the front...... It's Tu Tian!

After so many illusions, Qu Nanxiu enjoyed the pleasure of transforming into Tu Tian, and at the same time felt the heart-rending remorse and pain that Tu Tian experienced.

Who is Tu Tian? Is he evil?

Who is the woman who makes him remorse and suffer?

What is the relationship between Tu Tian and himself?

As he spoke, the white light came again, this time hitting the muzzle of the gun. Professor Luo watched Qu Nanxiu look in a certain direction in a daze, and no longer spoke, with surprise, usefulness, joy, and understanding and sympathy on his face.

What did Xiaoqu see?

At this moment, an antique town appeared in front of Qu Nanxiu's eyes, in the corner of the street lined with shops, there was a shop that had been idle for a long time, because of the large area and expensive rent, the general small business did not need to be so big, so it was idle day after day.

Early that morning, the early risers in the town unexpectedly found that the idle shops had been cleaned up, and a gold-lettered signboard was hung outside the door -- "Deceptive Pharmacy"! Dwarf, this name is really domineering! The point is that there is a line of small words below -- "Only regret medicine is sold"!

What is it? Only regret medicine is sold? There was a sigh in the crowd.

The pharmacy was surrounded by three layers inside and three layers outside, and everyone wanted to know who dared to boast in public about Haikou and how to justify it.

The inside of the shop is very spacious, but the furnishings are simple and empty. Behind the huge counter, standing was a heroic man in black who was about to stand about the age of eight, with thick eyebrows and deep eyes, not the appearance of a weak doctor who was the shopkeeper of an ordinary drugstore. On the contrary, his figure makes any woman feel thrilled and any man ashamed!

On the shelves behind him, there are hundreds of colorful bottles and cans, some tall and short, some round, some angular, some ceramic, some purple sand, some carved, and there is no decoration......

Each utensil itself is exquisitely crafted and can be regarded as a craft. As for what kind of medicine is inside, it is pills, powder, and water, and I can't see it, so it's even more curious. The mysterious pharmacy that suddenly appeared overnight, along with the furnishings inside and the handsome shopkeeper in black, became a mystery in the eyes of people.

There was a sign standing next to it: "Every time you pay for regret medicine, the price is eight cents." ”

At that time, you can buy a string of sugar gourds for two pennies, and Bawen is the price of four sugar gourds, as the price of catching medicine, it is really not much, and this exquisite bottle alone is far more than this price.

Finally, a man was willing to be the first to eat crabs: "Shopkeeper, how do you use this regret medicine, take it internally or externally?"

Qu Nanxiu, who incarnated as Tu Tian, seemed to be told how to answer every sentence, and everything was very natural: "Brother, your surname?"

"Don't give your surname Dong, a single-word name letter. ”

"Brother Dong in this life, can you have any heartache and regret?"

The man said: "Of course there is, I regret that I don't think about tea and food, and I can't sleep at night." But what's the use of regretting it when it's gone? People often say that there is no ...... after the sale."

Tu Tian smiled slightly: "I don't sell anything else here, I specialize in selling regret medicine." If you don't believe it, try it. Brother Tai may wish to tell, why do you regret it?

Unconsciously, many people had come up, staring at Tu Tian intently, listening with their ears up, for fear of missing a word.

Dong Xin said suspiciously: "The most regrettable thing is that before my father died of illness, I, as the youngest son, was far away from home and could not return in time to see my father for the last time." Thinking about it now, it still hurts. ”

As he spoke, his eyes turned red, and he had lost sleep for many nights because of this.

Qu Nanxiu, who incarnated as Tu Tian, was stunned for a moment: Why is he so much like himself?

So he patted Dong Xin's shoulder vigorously, expressing his empathy, turned around and took the fifth-ranked lake blue bottle from the second row of shelves, handed it over, and said, "Brother Tai is the first customer to buy medicine, so I won't take cashier, just treat it as a free trial." ”

"Is there such a good thing?"

There is no charge, which makes Dong Xin think that this is a joke even more, and makes him have a premonition that he has been tricked. Fortunately, he is not a good-looking person, and he does not feel that it is a shame to express the bitterness in his heart in front of everyone. Seeing that Tu Tian's expression didn't look like a joke, he hesitated to take it, thinking, can a person be resurrected after death?

He took the bottle and shook it, but there was no sound and almost no weight, like an empty bottle. It's even more bizarre.

"Just open it and the effect is immediate, but it's only valid for three days. ”

It was really an unheard of miracle, and the onlookers thought, I have to take a good look at this excitement today.

In front of everyone's eyes, Dong Xin carefully uncovered the cap of the bottle, and a dark blue light slanted out, shining on Dong Xin's face!

Everyone's eyes were about to pop out, and they all looked at the "guinea pig".

Seeing Dong Xin standing stunned for a moment, his knees suddenly weakened, and he knelt down with a "poof", crying: "Dad, the unfilial son is back!"

Dong Xin's eyes are no longer a pharmacy, without everyone and those bottles and cans, he is already in that sad rainy night many years ago - he was working outside, after receiving the letter from his father's critical illness, he hurried home, and when he arrived home, he was already covered with dust.

At that time, there was no convenient way of transportation, let alone mail and instant messengers, and it was a month after receiving the letter home.

When I pushed the door of the house, I saw my mother and all my brothers and sisters, hugging and crying around my deceased father, so I had lifelong regrets.

But since bathing in the blue light, he pushed open the door, and what he saw was clearly his mother helping his father to sit up and drink water, and the brothers and sisters stood in a circle, greeting him, the youngest brother, in surprise, a warm and peaceful atmosphere!

The seriously ill old man suddenly saw his youngest son who had been away from home for a long time returning, and his spirits were lifted, and he drank two large bowls of porridge for the first time, and held his hand and chattered for a long time. Three days later, Dong Xinfang left peacefully accompanied by his family.

Dong Xin saw his father for the last time, reunited with his brothers and sisters, and then accompanied his mother for many days, and arranged everything at home, so he was reluctant to leave, and there was no longer regret in his heart that he did not see his father for the last time.

The onlookers in the pharmacy witnessed the change of Dong Xin's facial expression, from excitement to calmness and satisfaction, which was very amazing, but they didn't know what he was going through. Seeing Dong Xin take out fifty yuan, he must Tu Tian accept it.

Tu Tian pointed to the sign: "I said that I don't charge money, if you have to give it, I will only charge eight wen, don't do more." ”

Dong Xin said: "I don't know why, I have never been so down-to-earth in my heart, and I don't have any regrets." This is not a lot of money, please be sure to accept it, because no amount of money can buy peace of mind!"

Everyone was amazed and wondered what had happened.

But Dong Xin didn't say much, and walked away with a look of satisfaction and gratitude.

Tu Tian moved his fingers, and the extra forty-two coins returned to Dong Xin's arms unconsciously.
