Xu Jing Era: Am I Not a Genius Qing Xu?

In 2039, humans suddenly discovered that "emotions" can be condensed into entities, called Xu Crystals: "Yue Crystals" condensed with joy can heal injuries and illnesses, and "Rage Crystals" condensed with anger can be used as energy sources. However, "turbid crystals" condensed with excessive negative emotions will pollute the minds of living beings and even give rise to "Emotion Variations."​ Only 0.001% Of the world's people can sense Xujing and are called "Thread-sensers"; among them, the even rarer ones can purify turbid crystals and control Xujing and are called "Qingxing people". The official "Xu Jing Administration" was established to supervise Xu Jing, while the black market breeds "emotion hunters" who plunder other people's Xu Jing for profit. The mysterious organization "Su Xu Hui" firmly believes that Xu Jing does not appear naturally, but is a "world experiment" released by a "higher existence". Beware of emotions!
