Heaven's Sorrow Immortal Gu

Imperial Minister Su names heaven’s sorrow Immortal Gu while explaining heaven’s envy Immortal Gu as a heaven path Immortal Gu, saying there are other similar Gu like heaven’s rage Immortal Gu and heaven’s sorrow Immortal Gu. He adds that not even a rank nine venerable can activate heaven path Immortal Gu of this type, then explains that an Immortal Gu like heaven’s envy can activate itself by resonating with emotions of envy and jealousy, at a huge price often paid in lifespan. Su Qi Han is hearing of heaven’s envy Immortal Gu for the first time when the minister explains it. ^{ch. 2121}
