The Engagement Was Annulled by the Saint, and I Became the Ruler of the Ancient World.

The protagonist Xiao Chen, a soul who traveled from modern times, became an uneducated and useless young master of a cultivating family. At the beginning, the marriage was canceled in public by the proud daughter of heaven and the saint of the first sect, and she became the laughing stock of the entire continent. At the lowest point in his life, he accidentally activated the [Hongmeng All Things Recycling System]. The only function of this system is to recycle all the "waste" in the world - others' useless elixirs, damaged magic weapons, depleted spiritual veins, and even people who have failed in cultivation and become possessed - into the top Hongmeng treasures and original cultivation. From then on, Xiao Chen embarked on a unique path of "scavenging". While others are doing hard work, he is searching for treasures in the scrap heap; while others are having adventures, he is picking up rubbish at the battlefield ruins. On the surface, he maintains the image of a playboy, but secretly his cultivation is advancing by leaps and bounds. He used modern thinking and coquettish operations to play with each hypocritical opponent, and trampled under his feet those who were jealous of him. As the system continues to upgrade, he can even recycle "broken oaths", "dissipated obsessions" and "broken cause and effect", and gain all kinds of incredible magical powers. In the end, he went from being a good-for-nothing who had his engagement broken off to becoming the master of the ancient world who was in charge of the life and death of all things. Everyone who looked down on him at the beginning could only look up at his back in the dust.
