After that incident in Tokyo, you experienced clinical death, your heart stopped for a minute. You don't remember anything, all you remember is how you saw the fireworks and that's it. one day after school, a man approached you and asked you to tell him the answers to a test (sorry, I do not know what to come up with)you refused, because you thought he was a fraud, and he slyly smiled and put a joker card in your jacket pocket, and from that moment on you were back in the borderlands. Why again? Because you've already been here when you had a cardiac arrest, but you don't remember it.

Not realizing where you are, you woke up in your apartment at your desk. You didn't see your parents and decided to go outside, but there's no one on the street. It's strange, Tokyo is usually crowded at this time. You saw the sign and there was a light at the end. You need to walk 17 km to start the games. You sighed irritably and started walking.When you finally got there, you opened the gate, and when you entered the "field" of the game, the gate closed.There were quite a few players. You put your hands in your pockets and approached a group of people. You looked around at everyone, they were all quite old, 20-40 years old. Suddenly, a woman's voice came from the speakers, and she began explaining the rules of the game. "Sacred Fortunes" game. This game, too, seems simple when it comes to rules. Each player is expected to draw a fortune slip and correctly answer the question on it to avoid facing disastrous consequences.If the answer to the question on the fortune slip is incorrect, fire arrows are shot; one for each margin of error in the player's calculation.

you saw how many people tensed up and started looking at each other.

It's been 10 minutes. Many people had already died from arrows, and it was terribly hot. You've been shot with fire arrows, and that's why it's very hot right now. Your clothes are a little tattered and sweat is dripping off you. It was the turn of the middle-aged guy. He pulled out a wooden stick under the number 58. He pulled out a note and his face clouded significantly

"the great curse..." he said to himself, and began to read the question aloud. "What is the population of the Earth in billions?What the hell," he turned to face the people. people started to get indignant. someone said it was a stupid question, someone silently began to say goodbye to the world, until you quietly mumbled the answer.

"8 billion," you said, not loudly, but not quietly either, so that the guy could hear. Arisu looked up at you and saw a young girl who looked 18 years old. The rest of the participants turned to you, hoping that this was the right answer.

"8 billion?exactly?Are you sure that's the exact answer?If this is not the case, then a million arrows will hit us.." Arisu said in a soft voice, hoping that you know the exact answer.
