"He's dead." The boy's tone was calm, and the peace did not match his age.

"You don't seem to care about his death." Rogier and Yue'er looked at the old man who was slowly walking to the coconut grove on the left after cleaning up the chaise longue and clucking it under his armpit, and the old man scanned the things that could be picked up on the beach as he walked, bending down from time to time to pick up cans or drink bottles.

"It was five minutes before he died, and I had already rehearsed his death in my mind. When he actually dies, I feel like a movie screening, and I tell you you you don't fully understand, and for sure if you have that experience, you won't be surprised by anything. The boy's long, unkempt hair was even more messy in the sea breeze.

"In that case, tell me how he died." Rogil's piercing gaze was fixed on the boy to see what he was going to say next.

"Oops, I guess I finished talking just around the time he died." The boy scratched his head with both hands, lifted his beach pants and said, "He's so old, and he's picking up rags." After living for so long, it's quite lonely. Long-term depression damaged almost his entire physical and mental system, and he had many diseases. Of course, the immediate cause of death was - he died by suicide. ”

"Suicide?" Rogier felt more and more that the boy in front of him was very weird, a private detective who had never been calm and silent, pursuing clues to find the past, and there was actually someone in front of him who could see the ability to see the future, and curiosity drove Rogier to continue to observe whether the boy's so-called "reasoning" was correct.

"But you know he's going to kill himself, so why don't you stop him? Is it because you can't change the trajectory? Or that you're lying. Rogier put on the frame of his glasses and spoke out his concerns.

"Your logical thinking is very thorough, you should be working as a police officer or a killer or something, you should know how detectives in foreign countries reason, right? My foreknowledge is purely scientific stuff, like weather forecasting. Deducing the subsequent state of an event from its initial state can also be called quantum effect computation. One of the most important aspects of quantum effects is the uncertainty principle, which excludes everything that is impossible through a calculation formula, and what remains must happen. However, here, the initial state of the event is negligible, and it is necessary to establish a predictive model to calculate, that is, it takes a period of time to measure and design the original molecular trajectory. To put it simply, my brain is the tray of the model, and everything that is going to happen is placed on the tray after the calculation. The boy finished speaking in one breath, then pointed to the old man's back and said, "There are five seconds left for him to die." ”

The three of them gathered their eyes at the same time to look at the old man, who walked very slowly, with a chaise longue under his left armpit and a colorful bottle on his right hand. Stunned! He suddenly had convulsions of his hands and feet, his whole body spasmed, and the things in his hands fell to the ground, and then he knelt on the ground and covered his chest with his right hand, and you can imagine how painful the expression on his face was. His head began to tremble irregularly, and he fell to the foot of the coconut tree with his limbs stretched out stiffly, struggling to twist the joints of his hands, and stuck his throat, and after a while, his face was red, his muscles were bruised, and crooked streaks appeared on his hands and body. Then he remained motionless.

"Impossible." Rogier was stunned for a moment, ran towards the old man's body, and when he arrived, he first measured his breath to confirm his death, and then checked the cause of death of the deceased. The deceased's face was red and his expression was painful, his earlobes were red and white, and his hands were stuck in his neck, which should be breathing, which was related to the lungs, and was very similar to poor breathing, and died of acute hypoxia failure. Is it a long-term accumulation of disease? No, the old man didn't smoke after waking up, and the onset of the disease couldn't be so rapid, so what was the reason? I heard the boy say that he committed suicide, so how did he commit suicide?

Thinking of this, Rogier took out his white gloves and put them on, and searched the deceased's body, except for some coins, dimes, and anti-cardiovascular medicines, there were no useful clues, he walked to the chaise longue, squatted down to check, and when he saw one of the glass bottles marked in English next to it, he immediately understood something. took off his gloves and put on his glasses, and said with a sneer: "Sure enough, it was suicide, or poisoning." ”
