By the end of the Difficult Dao Era he became the ruler of the Heavenly Jewel Kingdom and under his rule the Heavenly Jewel Kingdom was flourishing with life. He and Demon King Lun Ri were considered to be the greatest kings of the Grand Middle Territory.
Spy in the Cleansing Incense Ancient Sect
Later on Dong Shenglong reached an agreement with Cao Xiong that as long as he deliver Min Ren's Heaven's Will Secret Law to the Heavenly Jewel Kingdom, they would help him to become the Cleansing Incense Ancient Sect's next Sect Master and wouldn't bother the Sect anymore. Heavenly Jewel Mortal King then sent War Noble Lie with an army to attack the Cleansing Incense Ancient Sect, but entire army was instantly destroyed on the fifth day of siege by Immortal Emperor Min Ren's power. Heavenly Jewel Mortal King felt it and wondered whether it mean that the Cleansing Incense Ancient Sect still had an Immortal Emperor Life Treasure, but in truth it was a power from the Zither Pavilion, activated by Li Qiye.
War Noble Lie and Dong Shenglong were captured by the Cleansing Incense Ancient Sect. Heavenly Jewel Mortal King sent Violet Mountain Noble to stop their execution and even gave him an Amnesty Decree to guarantee the success.
Violet Mountain Noble used the Amnesty Decree to suppress the Cleansing Incense Ancient Sect's elders, but Li Qiye used Zither Pavilion's power to destroy the Amnesty Decree. The will of Heavenly Jewel Mortal King inside of Decree was provoked and immediately attacked Li Qiye, but he activated the Nine Saint Demon Gate's Heavenly Guardians; one of them reached out with a hand and easily destroyed Heavenly Jewel Mortal King's will.
The moment his will in the Amnesty Decree was destroyed, Heavenly Jewel Mortal King immediately felt it. He was enraged by such disrespect, but also terrified by how easily his will was destroyed. Not knowing what to do, he asked Heavenly God Ancestor for advice. Heavenly God Ancestor refused to leave his seclusion, so Mortal King asked for an Immortal Emperor Life Treasure instead.
Soon after the execution, Nine Saint Demon Gate's Demon King Lun Ri personally lead a delegation to the Heavenly Jewel Kingdom. Lun Ri and Heavenly Jewel Mortal King talked behind the closed doors and in the end Heavenly Jewel Kingdom announced that conflict between War Noble Lie, Dong Shenglong and the Cleansing Incense Ancient Sect was a personal matter, unrelated to the Kingdom's relationships with the Sect.
A month or so later the Evil Infested Ridge was ready to open up, so many sects and nations rushed to its entrance. Li Qiye also brought a group from the Cleansing Incense Ancient Sect. The Heavenly God Sect's disciples tried to stop them, but were quickly killed instead. To save Suppressive Might Noble from death, Heavenly Jewel Mortal King was forced to send Violet Mountain Noble with another Amnesty Decree and promise to not stop the Cleansing Incense Ancient Sect from entering the Evil Infested Ridge.
Attacking the Cleansing Incense Ancient Sect
Some months after the Ancient Heavenly Corpse Burial Ground closed, Heavenly Jewel Mortal King arrived at the Cleansing Incense Ancient Sect and demanded they hand over Li Qiye. If they did not comply, he would destroy the sect. When Li Qiye arrived on the scene, Heavenly Jewel Mortal King directly attacked the Cleansing Incense Ancient Sect with 10 000 of his elite troops. Before the battle could begin, elders from the War God Temple arrived, along with Lun Ri to stop the hostilities between the two sects. However, Li Qiye wouldn't let them leave so easily and attacked the with his Tetra-War Bronze Chariot and the four Tetra-War Stone Protectors. Heavenly Jewel Mortal King managed to escape with some of his forces thanks to the help of Qingxuan Xiong of the Azure Mysterious Ancient Kingdom.
Heavenly Jewel Mortal King had a clever and calculating mind; thanks to that the Heavenly Jewel Kingdom was flourishing with life under his rule. He was also very ambitious and wanted to transform the Heavenly Jewel Kingdom into an Ancient Kingdom.
Heavenly Jewel Mortal King was very talented cultivator.
