In the city after the spiritual energy was revived, Qin Xiao, a 23-year-old delivery rider, awakened an ability that was not impressive: after putting on a helmet, he could distinguish changes in wind pressure in streets and alleys from the sound of wind passing by, and be aware of the risk of water accumulation, cross winds and falling objects in advance. On the night when the red rainstorm warning was raised to the highest level, he received an urgent order for anti-rejection drugs that could not be discontinued. The platform constantly recommends the fastest route, but information about construction road closures is always slow. Qin Xiao not only has to compete with fallen trees, stagnant water, turbulent flow under bridges, and road closures around hospitals, but he also has to deal with his most difficult problem - always trying to prove that shortcuts are faster. Real delivery time after time made him understand that Tingfeng is not a panacea. What is truly reliable is ability, professional experience, on-site information and the judgment to look back. The heavy rain did not stop, and he began to compete for the first place in addition to speed.
