Fang Yuan accidentally bound the emotion collection system to collect players' emotional feedback to obtain top game technology and project funds. He gave up the fast-monetizing casual skin-changing games and concentrated on developing bridge-building simulation games. The first 98 levels of the game guide players to rationally plan their budget and build bridges, until the final level opens up an immersive experience, with vivid scene characters, allowing players to see the bridge they designed collapse with their own eyes, and receive a strong emotional impact.
