At the Beginning, the Hands Were Rubbing Gundam, and the Tribe Knelt Down and Shouted to the Gods.

The opening chapter needs to quickly establish a conflict: the primitive tribe is facing an existential crisis, and the protagonist arrives with a system cheat. The first task should be simple but demonstrative, such as purifying water, which not only solves the tribe's urgent needs but also demonstrates the system's capabilities. **Protagonist: Lin Yao** **1. Core identity and background:** 1. **Travelers:** are from modern civilized society and have cognition, thinking habits (such as Buddhism, survival, and infrastructure concepts) that are incompatible with the barbaric era, and lifestyle preferences (wanting to fish and become salted fish). 2. **The Chosen One/Civilization Sower:** With the talents of "Infrastructure System of All Realms" and "Hand of Creation", he is invisibly given the mission of leading or even reshaping the civilization of an era (the ultimate mission: building a megalithic civilization). 3. **Tribal patron saint and leader (the day after tomorrow):** Due to an unexpected "miracle", he was revered as a "god" by the Blackstone tribe and became the de facto spiritual idol and top decision-maker of the tribe. He needs to learn from scratch how to lead, protect and grow this primitive tribe. **2. Personality traits:** 1. **Initial mentality - Buddhism and Gou Ming:** In the early stage of time travel, the biggest wish is to live a low-key and safe life, with strong adaptability to the environment, but lacks the ambition to actively compete for hegemony, and has the pragmatism and a little bit of laziness of modern small citizens.
