Time, twenty-two o'clock in the evening.

In Adachi-ku, Tokyo, the secluded and narrow streets are empty, the street lights are cold, the people are sparsely populated, and the sound of cicadas is pitifully rare in late autumn. There are not many new and neat houses here, and the houses are not only old, but also mainly low-rent apartments from the Showa era.

A girl with long hair and a ponytail is walking briskly, just twenty years old, with a slender ponytail, wearing a black and red striped shirt trench coat, blue jeans, and canvas shoes. She held her collar up high, crossed the white plastic glossy film satchel, and pressed her right hand firmly on it, protecting a treasure.

When the electronic watch announced the time at midnight, Midong finally returned to her current residence, a low-rent apartment, Yonetianso.

It is a double-storey wooden building in the early Showa years, and it is said that it survived the bombing of Tokyo in World War II. Fortunately, the rent is also very cheap, and the price of 30,000 yen is the cheapest in all of Tokyo.

Midong stepped up the stairs to the second floor. The planks creaked from 10 years ago, the canopy from 5 years ago trembled slightly, the floor of the second-floor corridor was loose, and the railings were freshly painted. The tin door of room 205, with a small window next to it, is her home.

Standing on the second floor of the stairs, Midong looked back at the sidewalk, her eyes hard to hide her envy.

Cool street lamps shine on the dry asphalt road, and across the street is another low-rent apartment, Chaofengzhuang. The height of the third floor, the history of the Heisei era, and the quality are much better than that of Yonetagano, but the rent of 40,000 yuan per month is also something that Midon can't pay. Unattainable, the saddest thing is the most.

With a long sigh, Midong took the key from her deep pocket and opened the door to room 205.

However, it is a two-bedroom unit with a bathroom, kitchen and balcony. The smell of instant noodles has not yet dissipated, and the yellowed tatami mats are topped with stainless steel plates of pickles. The lights came on, and the newly replaced incandescent bulb sizzled, surrounded by three or two tiny flying insects.

After entering the house, Meidong did not rush to open the window, but quickly closed the door and ensured that the porch curtains were tightly covered. The next moment, she took off her shoes and socks, picked up a stack of clothes and put them aside, opened the plastic storage box below, turned through a large number of miscellaneous items, and took out a thick salary bag from the bottom.

"Fifteen Natsume Soseki, ......"

Midong sat cross-legged on the ground, counting the old coins that were crumpled inside. The pocket looks very thick, but it is only 27,000 yen in total, and the face value of 1,000 yen is only those numbers, and more of it is just a heavy steel hammer.

She then unzipped her satchel and removed the remaining bills from the inner pocket.

"Although the deposit has recovered to 200,000, tomorrow is the day to pay the rent, and the eldest brother's salary will have to wait until the middle of next month. In this way, the money that can be used to speculate in stocks is 30,000 yen, and the average interest rate of medium and long-term investment is X, and the short-term and ultra-short-term ......"

By the light of the lamp, Midong began to write hard at her desk, detailing the mathematical formulas of the Department of Finance in a black notebook. Her handwriting is small, but her strokes are full of heroic spirit of scolding Fang Xuan and pointing out the country.

In a moment, the complicated formulas had filled one side of the paper, and she turned the page, and the strokes kept writing.

After five minutes, the cell phone in the corner of the round table rang.

In fact, since Mei Dong entered the house, the prompt light on her mobile phone has been on non-stop, and she has missed calls or text messages, but she has no time to take care of it. But now that the new call is in front of her, she has no reason to ignore it, so she immediately dropped her pen and flipped the cover of her mobile phone.

The caller's name was not unexpected, she snorted softly and connected.

"Hey, big brother."

Mei Dong said smoothly: "I have already repaid this month's loan, I just counted the deposits, and after deducting tomorrow's rent, there are about 170,000 left." I'm optimistic about a newly listed super bull stock here, and I plan to invest in a medium to long-term stock starting at 30,000 yen, what do you think? ”

As she spoke, she brushed up again, drawing a simple periodic line chart with her freehand drawing skills as accurate as a computer.

"Ouch...... Old girl, you're really embarrassed for your brother. ”

A rough male voice sounded on the other side of the phone: "You know that your brother will sell coolies, and he asked me how to speculate in stocks." Ouch, if you really want me to go up, you have to pay for it. And the old girl, next time you talk slower, I'm ......"

"I haven't settled accounts with you this morning, so listen to me now."

Meidong hung up the phone and worked hard to write, using two things for two purposes, and not delaying.

"First of all, you have been sleeping on the construction site for the past few days, never leaving the workers, and going to the toilet is also hand-in-hand, you must remember. Second, you will free up to chat with me every day, this is a daily routine, and the time is indeed not fixed, and the workers also know that you have such a righteous sister as me, you must remember it. Third, your sister and I are a knowledgeable, well-mannered, well-behaved, innocent ordinary girl, and by no means a female ruffian who will hang out in Kabukicho in the middle of the night, this is the most important point, and I must remember it. ”

She spoke flatly, softly, in an almost dull tone, but she did slow down.

"W-What!?"

"You remember. And big brother, you must remember that I like women. ”

"Huh...... Sister, what's wrong with you, this is ......"

"Just remember these points."

Midong flipped another page of her notebook and continued her financial analysis: "Nothing should happen, but maybe something will happen." In short, you remember these points, as for the purpose of remembering them...... Trust me, you'll know what's going on when you need it. Hopefully, you won't have a chance to use it. ”

"Sister, you know that my brother's brain is not good for ......"

"So I bought you a mobile phone with automatic recording, above, hang up, I still have something, bye."

Midong flicked the flip cover, hung up the phone, and finally left a deep handwriting on the notebook. The mobile phone and water-based pen were put down at the same time, and she got up and twisted her waist, but after only a dozen seconds, she turned around and outflanked her shoulder.

“…… Well. ”

Midong carefully sorted out the contents of the bag, headband, lipstick, makeup mirror, toilet paper, wet wipes, and a lot of odds and ends, but not a single banknote was found. The banknotes taken out of the deceased's wallet had been stuffed into her salary bag and hidden at the bottom of the storage box.

"Tsk, damn bikers."

However, Midong was distressed to find that there was a gash at the bottom of her well-behaved satchel.

"Should I thank them, or should I castrate them!?"
