Main plot: After the great catastrophe, the ancient martial arts world was reduced to a wasteland. Xiao Yao, a passionate orphan who lost his country, accidentally obtained the "Red Envelope Devouring System", which can be used to gain martial arts, resources and luck by devouring the "Calamity Red Envelopes" scattered after the catastrophe. While wandering, he rescued the charming Su Rao, the leading dancer of Zuixianlou, and the two of them joined hands to fight against Lin Mo, the leader of the "Black Tribulation Sect" who had turned black due to a catastrophe. Xiao Yao upgrades the system by grabbing red envelopes, gradually uncovering the truth of the great tribulation (celestial beings test humans), and finally defeats the blackened villains and celestial being invaders, becomes the "tribulation lord" who protects the wasteland, and stays with Su Rao for the rest of his life. Highlights: The flow of red envelopes is cool (swallowing red envelopes to gain magical skills/resources), the emotional interaction of the enchantress heroine, the high-burning confrontation of the darkened villain, and the growth curve of system upgrades
