The Seal of Samsara was among the top ten Peerless Heavenly Weapons on the first page of the Exchange Manual of Samsara. Being rated as the most mysterious weapon, the Samsara only had a sketchy information about it. According to the description on the manual, the seal was created by the Earth Goddess - the one who attained the Nirvana Realm along with the Celestial Ruler - during the Ancient Times.
The Earth Goddess took pity on all living creatures because they had no chance to live a future life after death. When they were dead, they would either drift into chaos or become evil spirits. Therefore, using the Dao Fruition of Half-Step as material and the Nine Nether as fire, the Earth Goddess had created the Seal of Samsara. In order to do that, she had even turned her own body into a furnace. However, as she had not attained the Realm of Dao Fruition yet, the seal was only half-finished. Its function was still unknown.
