I Was a Scumbag and Spread My Teachings Across Borders and Became the Master of All Demons.

Chen Yan bought a honeycomb fossil at the antique market, but became the only traveler connecting the modern city with the wild world of monsters. The giant trees here are towering to the sky. He uses various precious resources here to quickly convert them into wealth in the modern city. When he used a self-defense welding torch to kill monsters and a drone to explore unknown areas, he finally discovered that the Taoist knowledge he brought with him was the most terrifying power in the world! The half of the "Breathing Method" he passed on to the dying boy gave humans the first ray of capital to fight against the monsters. The "Purification Sutra" he read to the seriously injured little demon actually made it become enlightened and advance, and it regarded him as its reborn parent. From then on, Chen Yan's cross-border life was completely overturned: In the real world, he founded the "Early Yuan Ecology", used rare treasures from other worlds to build a business empire, and chatted and laughed with business giants. In the world of monsters and beasts, he was sitting on the preaching stone in the scorched wood forest. All the monsters below bowed their heads. The human monks stood in awe and shouted in unison: "Ask the teacher to give a lecture!" When the hostile demon emperor came with his demon soldiers, vowing to crush this "heresy". Chen Yan just calmly put down the tea cup in his hand and said calmly to the Demon Saint disciple standing beside him: "Go tell it." "If you want to learn "Xiaoyaoyou", you must first learn to line up and pay the tuition."
