He transformed his weapon into the Purple moon to help demon clan to cultivate. Because of the purple mooon, he has another nickname of Zi Yue demon lord.

The purple moon transformed back to his weapon when he decided to take bach the power and returned to True God level in eps 41 of ALP. However, his house/manson where he lived in the Demon Realm located in Zi Yue  Mountain. The area was named after Purple Moon. And Jiu Yu where the ancient devils and Ming Kai (actually Xuan Yi in the novel) was sealed was located inside Zi Yue Mountain. The Last Immortal changed "the container of Jiu Yu" into Purple Moon

I get it now, thank you for this explanation ❤️

 H19279:

In term of original work, those 3 novel are somehow connected. However, when adapting on screen, the links were weaken or eased due to copywright. As you can see in The Last Immortal, many characters' names who were also included in ALP were changed. They also simplified some details such as Yuanqi's father. In TLI, it's said that Yuanqi's father had lived in Ziyue (purple moon) but in fact it should be Tianqi who was demon True God.

Ohh, thank you for the explanation!! Can't wait to binge the episodes over the weekend!

Thank you for pointing that out! You're absolutely right—Tian Qi was undeniably attached to Shanggu. That’s why it would be so intriguing if he had lingering affection for Yue Mi without fully realizing it. After all, feelings don’t just emerge out of nowhere; there’s always a spark—like when he unearthed the wine she made for him.

Tian Qi has always been mischievous and a bit childish, so it’s not a stretch to see his feelings for Shanggu as something akin to puppy love or even brotherly affection. But his bond with Yue Mi feels different, doesn’t it? Do you really think Tian Qi naming his divine weapon “Moon” was just a coincidence? The word “Yue” (Moon) seems to hold far more significance to him than he consciously realizes.

Think about it—he drank wine with her, played chess with the stars alongside her, raised Shanggu together with her, and even admitted to feeling lonely in her absence. Maybe he cherished Yue Mi far more than we ever gave him credit for.

I’d love to see him come to terms with his mistakes in this drama. And honestly, it would be so satisfying to watch Yue Mi stand her ground and hold him accountable after all those years of enduring his obliviousness to her feelings. She deserves that moment!

I have been digging a lot in meaning of names for characters in ALP/Shanggu such Bai Jue, Qing Mu, Tianqi etc.
In term of Purple moon I think he used "moon" to imply himself - the object the shone over Demon Realm.
In the novel, Tianqi had purple eyes and hair.  Thus it is reasonable he used Purple as his trademark. His assistant's name is Zi Han. And you can see all of his clothes had purple shade. 

He was the only True God who had demon power/nature. Thus he also looked after the Demon Clan. The demon clan was usually considered as "dark side" , the demon realm was depicted as "dark" too.  Therefore, the moon played as the symbol for the shining object for demon realm.
Additionally, the name of Zhi Yang's weapon is Sun & Moon Spear (日月戟). Don't you think Zhi Yang also had affection to Yuemi subconsciously, do you?
