Douluo Continent: Copying Ya Li, the Carefree King of the Sun and Moon

[Multiple female leads + behind-the-scenes plot + anti-Tang Dynasty + anti-Shrek + unification of the Sun Moon Empire + reform + not becoming emperor + carefree king]
Xu Yanli transmigrated into the world of Douluo Continent II: The Peerless Tang Sect. The stupid system ran away overnight, leaving him only with Ya Li's Prayer Angel template and his original martial soul before disappearing.
As Xu Tianran's younger brother, whom he raised from childhood, he possessed twin martial souls that defied the heavens: the Sun and Moon Holy Prayer Angel and the Purple Emperor Annihilation Dragon, embodying both life and destruction.
He had no desire for the throne; he was not interested in power and only sought a carefree life. His sole goal was to become a god.
Upon awakening his martial spirit, he was immediately bestowed the title of the Carefree King.
His elder brother suffered from a leg ailment, which he cured. Occasionally, he would offer insightful advice and perform surgery on the Sun Moon Empire.
When the sect provoked him, he swept away the threat with the power of the Purple Radiance Annihilating Heaven Dragon.
He infiltrated Shrek Academy for a year, stole Electrolux, and took Huo Yuhao, Xiao Xiao, and Jiang Nannan with him...
When the world threatened to shake the heavens and the earth, he used the dual divine thrones to suppress the universe.
When he unified the world, Xu Tianran was exhausted.
Gentlemen: Please let the carefree king be emperor.
Two divine kings descend upon the world, angels illuminate the sun and moon, and dragons shatter the heavens!
The God of Life, the God of Destruction.
