I Became a Saint Through Merit in the Demonic Cult

Tu Feng, who was originally an underground boxing champion, was shot dead on the street because of fake boxing. He accidentally discovered that he had traveled through time and became the Holy Son of the Demon Sect, and just as he was planning to do all the bad things, he awakened the "merit and sainthood" system... I didn't expect that the demonic sect in this world is not like the demonic sect, and the righteous way is not like the righteous way. Today I will promote truth, goodness and beauty, and fight against falsehood, evil and ugliness!
