Villain: My Sister Is the Heroine of Destiny

Shang Beichen traveled to an urban online world. He did not become a protagonist favored by fate, nor did he become a villain with a top-notch family background. Instead, he became the younger brother of the heroine. He is a little depressed! But as time went on, he felt... "It seems to smell delicious!" Anyone who goes out with the name of a villain will get three points of punishment. Who was bullied? What's going on? The villain brother immediately came to help! Even the protagonist who had a grudge against him at the beginning started to please him. But they all want to take his crystal, and he has a mission to protect the crystal and prevent bad guys from getting close. Doesn't this seem like he has no choice? Shang Beichen: "You are very kind to me, and I don't want to come to this point, but you want to take my crystal, and I can't treat it as nothing, and... I am also a villain."
