A tall man with gold hair. Before he reached Titled Douluo rank, he looked like a fourty year old man. After the breakthrough, he gained a youthful appearance.
He was a Sabersoul that took human form after its consciousness awakened and cultivated. The saber was created by the Dragon God, using his own horn. He made it to be the executioner of the law for dragon clan members who committed evil and injustice. Before the Dragon God fell down in the middle of the battle between divine beasts and deities, he sent the saber into Douluo Planet, a planet that has rich life force. In the journey of cultivation, Sima Jinchi can't breakthrough to Titled Douluo because the skill in the ninth soul ring can only be activated by the Dragon God. Due to aura of the Dragon God within Tang Wulin, which he received after all dragon souls in Valley of Dragon Graveyard gave him the Dragon God's blessing, every time Sima Jinchi sparred with him, Sima's spiritual power increased. Thus he was able to gain the ninth Spirit Ring and reawaken his slumbering memories.
