Being publicly humiliated by his money-worshiping girlfriend, Lin Xi returned to the rental house, but activated the Ten Thousand Realms Chamber of Commerce that linked the heavens.
While others were still trading goods, he was exporting entire civilizations. Use "Sun Tzu's Art of War" to help the elves win the holy war, use Confucian classics to enlighten the demon lords, and sell the Star Destroyer blueprints to the world of cultivation.
When leaders from various countries treat him as a guest, and when gods from other worlds pray to him for knowledge, Lin Xi holds the fire of civilization and smiles calmly:
"Don't worry, the next one to conquer is the sea of stars."
