In the TV series "The Last Immortal," the story primarily takes place in the Lower Three Realms as the ancient divine realm remains mostly closed off. The Lower Three Realms consist of the Celestial Realm, Demon Realm, and Underworld Realm, with the Demon Realm being particularly unique. The third level of the Demon Realm seals another realm known as the Nine Abyss Tartarus or the Nine Underworld Purgatory, also referred to as the Demon Realm.

Among the rulers of these three realms, most aspire to become the supreme ruler of the Three Realms, whether it be the Demon Lord, the Heavenly Emperor, the Demon Emperor, or the Ghost King. In this series, there are three Heavenly Emperors, two Demon Emperors, and three Demon Lords, along with two Ghost Kings. Today, let's discuss the rankings and ultimate fates of these ten mighty beings.

1. Demon Lord Xuan Yi:

Demon Lord Xuan Yi is the god of the Demon Realm. Originally the Primordial Chaos God, he was imprisoned in the Nine Underworld Purgatory after betraying the divine realm. He has always been indifferent to worldly affairs, even when Qing Lin stirred up chaos in the Three Realms. Xuan Yi is the most powerful among the true gods, surpassing even the likes of Ancient Bai Jue. In the end, he personally revived Yuan Qi, who sacrificed himself to the Chaos Origin.

2. Ghost King Ao Ge:

Ghost King Ao Ge's true identity is a god from the divine realm. After his younger brother died in the war between gods and demons, he pleaded with the ancient beings to help gather his brother's soul, which then reincarnated within him. Ghost King Ao Ge is the ruler of the Ghost Realm, also known as the Underworld Realm. He created the opening song of the first episode and later helps revive A Yin.

3. Heavenly Emperor Feng Yuan:

Heavenly Emperor Feng Yuan is the ruler of the Heavenly Realm and a close friend of the ancient beings. When Phoenix's soul scattered, she secluded herself to nurture Phoenix's soul. Later, Demon Lord Qing Lin and Peacock King Hua Mo joined forces to endanger the Three Realms. Feng Yuan used half of her power to strengthen the seal on the Nine Abyss Tartarus, resulting in a loss of strength. Fortunately, she eventually reached the realm of the Supreme God, ascended to the divine realm, and gave Phoenix hope for resurrection.

4. Demon Lord Hua Mo (Peacock King):

Peacock King Hua Mo may appear to have a weak strength, but in reality, he is incredibly powerful. He secretly colluded with the Demon Lord and practiced demonic techniques, devouring the cultivation of many members of the Eagle and Peacock clans. His strength has reached the realm of the Supreme God. However, due to his half-hearted nature, he dared not confront Feng Yuan until he felt confident enough. He wanted to use the Demon Gathering Banner to annihilate the Immortal Clan but ultimately met a tragic end beneath the banner.

5. Demon Lord Qing Lin:

Demon Lord Qing Lin herself is a member of the Nine-Tailed Fox clan, but her luck turned around after being punished by the ancient beings and sent to the Nine Underworld Purgatory, where she gained a strand of Xuan Yi's divine power. As a result, she obtained the power to control the God-Killing Flower, which became the foundation for her later rebellion.

Possessed by Hong Yi, she destroyed the Great Marsh Mountain and killed Heavenly Emperor Lan Feng. Her strength should be on par with that of a Supreme God. Unfortunately, she met a tragic end under the Yuan Shen Sword.

6. Heavenly Emperor Lan Feng:

Heavenly Emperor Lan Feng can be considered the most unfortunate. Originally the heir to the Heavenly Emperor, he was surpassed by Jing Jian. Later, when Phoenix became the Heavenly Emperor, he became the heir once again. Before reaching five hundred years of age, he reached the peak of the Supreme Lord, with exceptional strength. However, when Phoenix secluded herself, he became the interim Heavenly Emperor. He tragically fell in love with Hua Shu but was ultimately plotted against and killed by Hua Mo, dying by the hands of the Demon Lord—a truly lamentable fate.

7. Ghost King Xiu Yan:

Ghost King Xiu Yan was also a Supreme God of the divine realm and A Ge's brother. Unfortunately, he was injured during the war between gods and demons, and his strength has not yet fully recovered to the level of a Supreme God. However, he plays a significant role in the Underworld Realm. After A Yin's soul scattered, he assists her in reincarnating continuously until she achieves nirvana and becomes Phoenix.

8. Demon Emperor Lin Sen:

Demon Emperor Lin Sen was extremely arrogant and possessed the strength comparable to a Supreme Lord. However, he did not consider Demon LordQing Lin a threat and fell into her trap. She used the God-Killing Flower to control him and forced him to fight against his own people. In the end, he was killed by Demon Lord Qing Lin, meeting a tragic fate.

9. Demon Emperor Bai Jue:

Demon Emperor Bai Jue was once the most powerful existence in the Demon Realm. He was known as the Ancient Demon Emperor and possessed strength surpassing that of a Supreme God. However, he was sealed by Xuan Yi in the Nine Underworld Purgatory for betraying the divine realm. Although he was eventually released, he fell into the hands of Demon Lord Qing Lin and was killed by her.

10. Heavenly Emperor Jing Jian:

Heavenly Emperor Jing Jian was once the most promising disciple of the ancient beings. He possessed extraordinary talent and was the hope of the Heavenly Realm. However, he fell into the scheme of Demon Lord Qing Lin, who used the God-Killing Flower to control him. He fought fiercely against Heavenly Emperor Lan Feng and ultimately perished.

These are the power rankings and fates of the ten mighty beings in "The Last Immortal." Their interweaving destinies and struggles for power make for an epic and captivating storyline in the Three Realms.
