In terms of strength ranking in Tales of Demons and Gods, even though Nie Li is only a Gold rank Demon Spiritualist, he has countless methods and treasures. From the overall strength ranking of Tales of Demons and Gods, there were the top ten characters (in no particular order): Heavenly Dragon Immortal Emperor, Nine Dragons Sovereign, Nine Nether Blade Emperor, Primordial Demon Sage, Emperor of the East, Nine Nether Python, White Bone Emperor, Supreme Immortal Venerable, Heavenly Dragon Great Dao Man, and Earth Immortal Yan. Nie Li's exact ranking was not clearly shown, but it was clear that there were many powerful characters ranked at the top. However, Nie Li relied on his unique cultivation technique, the Heavenly God Technique (although his cultivation speed is slow, his strength is solid), his powerful demon spirits (like the Fanged Panda), and many other treasures (like the Temporal Demon Spirit Book's remnant page, the Nightmare Demon Pot, etc.). His performance in battle was extraordinary, allowing him to contend with opponents whose strength was higher than his.

According to the information he has, Nie Li's strength is extremely powerful. His cultivation technique and demon spirit were provided by the [Heavenly God] technique. He could fuse with five demon spirits at the same time, which gave him a powerful ability in battle and allowed him to challenge opponents of a higher level. In the genius battle, he had defeated his opponents in all three matches, just like how he had killed Shen Fei, who was a silver rank. Even though his leveling speed was slow, the [Heavenly God Technique] made him stronger. Nie Li was able to defeat the Sacred Family's Gold rank Demon Spiritualist Shen Ning and the Gold rank Demon Spiritualist Shen Xiao who had taken the soul realm strengthening pill. His true strength should be far above Gold rank demon beasts, perhaps even close to Black Gold rank. In addition, after Nie Li used the knowledge from his previous life to be reborn, he led his companions to create many miracles. As the story developed, his strength continued to grow and improve. However, the text did not clearly state the details of his final strength. " Yun Anlu's Body Sacrifice " is equally exciting. Everyone is welcome to read it!
In the Tales of Demons and Gods mobile game, Nie Li was initially an R rank Demon Spiritualist. Nie Li once killed an Abyss Demon and defeated a Black Gold rank Demon Spiritualist. His combat strength has reached the rank of a Gold rank Demon Spiritualist. In the battle with 3-star Gold rank Ye Han, Nie Li was able to tie with him even though he was a 5-star Silver rank. His strength can't be judged purely based on his rank. With the battle experience and techniques he had accumulated in his previous life, he could fight above his rank. In addition, Nie Li can fuse with Shadow Demon (1 time God Level growth assassin demon spirit), Fanged Panda (1 time God Level growth Berserker demon spirit), Bloodwing Saint Jiao-dragon (1 time God Level growth dragon blood demon spirit) and other demon spirits (due to the [Heavenly God] cultivation technique, he can fuse with seven demon spirits). In terms of his soul realm, his soul realm was red. In his previous life, it was in a messy shape and had no attributes. His spiritual root was an 8-grade Heaven Spiritual Root (he withdrew his hand before the test ended, and it was suspected to be a 9-grade Heaven Spiritual Root). In his previous life, he only had a 7-grade Earth Spiritual Root.

Who Nie Li likes in 'Demon God' is a rather vague question because Nie Li didn't express his feelings clearly in the novel. Although Nie Li is a charming character, he isn't a very emotional person. His love life is relatively cold. In the novel, Nie Li had come into contact with many women, but he didn't show any special feelings for them. The relationship between him and Su Mo was rather complicated. Although Su Mo had a good impression of Nie Li, Nie Li did not show the same feelings. In addition, Nie Li once had a romantic relationship with Bai Qian. However, the relationship between them wasn't pure love, but rather, there were some elements of exploitation. Nie Li's love life in 'Demon God's Record' was relatively simple. He didn't show any particularly affectionate side, so he couldn't be sure who he liked.
Nie Li had a total of five wives, namely Ye Ziyun, Xiao Ning 'er, Yu Yan, Xiao Yu, and Long Yuyin.
