At 18:03 on June 19, 2503, I was conducting repeated monotonous digital confirmation work with my colleagues in the laboratory. It has been two years and eight months. Since I was confirmed to be included in the list of scientific researchers called "Butterfly Ban" experimental program, I was secretly sent to this underground laboratory, and the laboratory staff were performing the tasks assigned by Alice.Butterfly half plan, we have to perform a large number of digital calculations and confirm at each stage. Although quantum computers with ultra-high speed can be replaced, this plan is still required to pre-calculate the formula and obtain a low-precision result. Alice performs high-precision digital calculations, and finally compares them with each other to confirm the problem. If something goes wrong, the experimenter starts over and adopts a new deduction algorithm until the numerical results in the first half are exactly the same, and then it is included in the effective data of Butterfly half program, for what seems so harsh and complete.The boring work that can be left to the computer, but the laboratory staff present were not irritable, but were full of energy, because the work was coming to an end. When I looked at the holographic projection of the "Next-Era Quantum Collider" in the center, my heart was thumping. At the age of 23, I was able to participate in the greatest experimental plan in human history. I was satisfied for my whole life. I was excited to think about how to explain the reason for the disappearance of my girlfriend Xiaodie in the past two years and eight months. I couldn't help but speed up a little and report to the blurred glass compartment.
