My girlfriend is actually myself.

Chapter 10 Traveling Alone

As soon as he got home, Shiraishi Saku was cornered in the bathroom by his younger sister.

The plot is developing a bit strangely; shouldn't it usually be the other way around?

"Want to play a toilet-grabbing game?" Shiraishi Saku thought back to when they were little, his little sister always had to be the first to sit on the toilet on the second floor.

Sakura Nene was not led astray by her brother. She raised her head, her small face showing a mixture of emotions: shock, grief, and pity for the criminal.

"I recognize him!" she said seriously.

"What did you recognize?" Shiraishi Saku thought of the 3D model on the computer. If the girl was talking about that, there was nothing to worry about, but if she was talking about something else, then it would be a bit troublesome.

"Even though she has blonde hair and blue eyes, she's the girl from the news before, she looks exactly the same!" Sakura Nene took out her phone, turned on the screen, and showed Shiraishi Saku the news picture.

The smiling black-haired girl in the picture, aside from her hair and eye color, bears a striking resemblance to Yukimiya Natsune.

You actually found this? Are you still that silly little sister?

Yukimiya Natsune is certainly not the girl in the news, but Shiraishi Saku did refer to this photo when making the model.

He considered making some improvements, but aside from hair color, eye color, and a few minor details, any other changes would only ruin the beauty of the face.

This resemblance is not a problem; there are many people in the world who look alike, not to mention the essential differences in hair and eye color.

"You watch the news regularly?" he asked his sister in surprise.

Although the incident in the news caused quite a stir three years ago, and the girl's body is still missing, it is ultimately just an event without much drama or emotional impact. It is easily eroded by time, and no one will remember that this silly little sister remembers it so clearly.

Faced with Shiraishi Saku's question, Sakura Nene guiltily looked away.

She wasn't interested in the news; she found the news photo in her brother's browser bookmarks during the last big clean-up.

She started by complaining, "Don't change the subject! What exactly happened to her?!"

Shiraishi Saku took her phone, pulled her into the living room, enlarged the half-body photo, and placed it next to Yukimiya Natsune.

He pointed to the flat chest of the half-body photo, then to the high chest of Yukimiya Natsune.

Sakura Nene scratched her head. Hair can be dyed, and eyes can be made with colored contact lenses, but breasts can't be faked.

She reached out and pinched it; it was the same as her mother's, it was indeed true.

The girl walked away guiltily. If it were just a matter of resemblance, she wouldn't have connected the two people, but her brother kept news photos, and a girl who looked very much like the one in the news photos suddenly appeared next to him, so it was hard for her not to have some wild thoughts.

Realizing that her brother wasn't the kind of criminal who imprisoned missing girls, Sakura Nene was a little disappointed.

Because of this misunderstanding, and the fact that she had saved his life that afternoon, the girl tacitly agreed to let Yukimiya Natsumi stay temporarily, and Shiraishi Saku and Yukimiya Natsumi's prepared deception and coercion were useless.

Sakura Nene brought out the food from the kitchen, and the two of them sat down at the dining table.

After dinner, they cleaned up the table and kitchen together, mainly with Sakura Nene doing the work, while Shiraishi Saku was responsible for taking out the trash.

After tidying up, Sakura Nene went back to her room to do her homework, while Shiraishi Saku and Yukimiya Natsune stayed in the living room.

It was already dark, and it wasn't convenient to go out to buy clothes, so he and she continued to do some additional experiments.

The two bodies each wore headphones, listening to Chinese and Japanese respectively, and answered the listening comprehension questions using their respective Chinese and Japanese thought processes, without any problems.

Two bodies each hold a handle, enabling them to travel together without injury, demonstrating perfect teamwork.

From now on, he can play all two-player games by himself, which is great news.

Next, they compared and recorded the strength, agility, and reaction speed.

There are some differences in physical fitness; teenagers are stronger, while girls are more flexible and can perform yoga poses that teenagers cannot. However, there is no significant difference in reaction speed between teenagers and girls.

These three are the fastest and clearest to test. Other tests are too slow and troublesome, so we'll put them aside for now and take our time.

Next came the intellectual challenge. He and she used different civil service exam questions, answered them together, finished them together, and their scores were roughly the same.

There is no significant difference in intelligence.

Finally, and most importantly, is the intelligence gained through collaboration.

He and she had just chosen a two-player game for a final test to determine if they could apply this individual skill to coordinated cooperation.

Similarly, they also need to test whether their two independent brains can work together.

Shiraishi Saku and Yukimiya Natsune left the living room, went upstairs, and entered their bedroom.

There was only one chair in the bedroom, placed in front of the desk and computer. Shiraishi Saku sat in the chair, and Yukimiya Natsune sat on his lap.

It felt even softer than when my sister was sitting in my lap.

Shiraishi Saku bent down and pressed the computer's power button, while Yukimiya Natsune raised her hand and pressed the screen's power button.

The screen lit up, he picked up the mouse and opened Google, she touched the keyboard, typed words, and searched for math olympiad problems.

On the webpage, a dense array of links appeared. He picked one and clicked it, while she picked up her notebook and two pens.

Shiraishi Saku answered the questions on the right side of the notebook, while Yukimiya Natsumi answered them on the left side.

This is not a competition; what they are looking for is a question that he or she cannot answer on their own.

Soon, Yukimiya Natsune encountered a geometry problem. After thinking about it for ten minutes without success, she handed it to Shiraishi Saku, who also couldn't solve it after thinking about it for ten minutes.

The two bodies looked at each other, and their two brains synchronized, both starting to think about the problem.

Formulas and inspiration intertwined and collided in the two heads, and the computing power of the two brains was bound together by a soul.

A minute later, Shiraishi Saku and Yukimiya Natsune gave their answers together.

The answer is correct.

The problem, which took each of the two bodies ten minutes to solve without any clue, was now solved in a minute by combining the efforts of both brains.

Moreover, within that minute, there is also time for the initial adaptation and integration of the two hemispheres. If you remove these, the actual time spent thinking is probably less than half a minute.

Shiraishi Saku knew very well that he was not a genius, and his excellent grades were only due to his memories from his previous life. But now, with Yukimiya Natsune as his partner, he had undoubtedly crossed the threshold of genius.

If this applies to intelligence, what about physical abilities? Since the brain can coordinate, perhaps the body can too.

Yukimiya Natsune raised her hand and touched Shiraishi Saku's chin, while Shiraishi Saku raised his hand and scratched the back of Yukimiya Natsune's head.

When I have time, I'll also arrange to exercise.

Yukimiya Natsune reopened her notebook, and Shiraishi Saku wrote down his conclusion.

1+1>>>2

Tonight's exploration is over. The four hands get to work, pick up the eraser, tear the paper, splash some water on it, and throw it into the wastebasket.

Next was time to relax. They went downstairs, lay on the sofa, and started playing games.

Shiraishi Saku has already completed "Two People Together" with his sister, but playing with two people is never as enjoyable as playing alone.

When two people play, each person can only enjoy 50% of the fun of the game, but when one person plays, they can enjoy 100%!

Shiraishi Saku and Yukimiya Natsumi quickly became engrossed in the game. They could communicate with each other through thought alone, without needing to speak. The only sounds in the living room were the changing lights of the screen and the game's sound effects.

The sofa in the living room wasn't deep enough to be comfortable. During the cutscene, Yukimiya Natsune slumped over and lay on Shiraishi Saku's lap. Shiraishi Saku then lay down and rested his head on the girl's soft thighs.

The two bodies shifted and rubbed together, finding a comfortable lying position.

If Sakura Nene were here, she would definitely yell, "What a shameless pose!"
