In the mystical world of 2419, an increasing number of residents are moving to EZVIZ Future City. As the city expands, many issues arise, the most significant being insufficient production capacity, leading to severe shortages of various goods and an inability to meet the daily needs of the residents. To ensure the residents' daily lives are not disrupted, a tech company has created the [EZVIZ] Companion Group, modeled after EZVIZ, and developed mechanical bionic animals and child service robots based on EZVIZ technology, forming a new service team for the future city. This service team operates within the EZVIZ base, producing the necessary materials for the residents. In return, the residents provide a unique mineral to the future city: crystal stone. The crystal stone is then reinvested into the city's production, creating a continuous cycle that drives the vibrant growth of the future city.
