Civilization Trial Ground: I Made up a Human Epic

Lin Xuan was selected to join a super-dimensional game called "Civilization Trial Field" to compete with other civilization masters. Other people's civilizations are orcs and elves, but Lin Xuan's initial race is "Homo sapiens" who have just learned to use stone tools. Lin Xuan can only use the "Civilization Editor" to inject soul into his tribe: fabricate a "mythical age" and give them a cultivation system; write a "heroic epic" to create an unyielding spirit for them. When other civilization masters laughed at Lin Xuan's weakness, he silently pressed the buttons of "Industrial Revolution" and "Scientific Enlightenment".
