I Use Merit to Add Points, and My Output Depends Entirely on Salvation!

This is a modern alternate world with "forgotten history". Skyscrapers and ancient sects live side by side, and spiritual power-driven speed cars shuttle between suspended mountains. Students study both "Basic Qi Refining Techniques" and "Realm Laws and Psychic Engineering" in the "Tianshu Higher Cultivation Academy". Lin Ye, a young man with a mysterious life experience and forbidden blood flowing in his body, was forced to embark on a strange road of becoming stronger after awakening to the "merit and sainthood system". While others were fighting life and death in the secret realm, he helped the old lady cross the street on the street; while various forces were fighting for the ancient ruins, he was silently completing the bizarre tasks issued by the system such as "purifying the siltation of the earth veins" and "mediating neighborhood disputes", and accumulating insignificant "merit points". Everyone laughed at him as a "bad guy" who didn't want to make progress and was a shame to the world of cultivation. Including the hypocritical student council president, the heir apparent of an aristocratic family who was jealous of his favor with the goddess, and the childhood sweetheart who seemed weak but was actually yandere. Until one day, the sealed ancient dragon king awakened in the Arctic ice field. Dragon power swept the world, and modern psychic weapons were eclipsed by the mythical power. He raised his hand towards the dragon shadow that covered the sky and the sun, and the system interface flashed in front of his eyes: Warning! An apocalyptic threat detected!
