Xiao Yan’s legendary journey in the Central Plains was marked by many intense battles and breakthroughs, but among his most iconic achievements was the subjugation of four powerful Heavenly Flames. These rare and destructive flames, each with unique traits and immense power, were critical to Xiao Yan’s rise in strength. But which flames did he acquire, and among them, which one stood out as the strongest?
1. Ocean Heart Flame (Ranked 15th)
The first flame Xiao Yan obtained in the Central Plains was the Ocean Heart Flame, which held the 15th position in the Heavenly Flame Ranking. At the time, it was under the control of Elder Mu Gu, a high-ranking member of the Soul Palace. Xiao Yan encountered him during the Heaven Talisman Alliance’s offensive on the Soul Palace’s Tiangang Hall. After years apart, the two crossed paths once again — but this time, Xiao Yan had already reached the level of a Dou Saint. Displaying overwhelming power, Xiao Yan effortlessly defeated and killed the Four-Star Dou Zun Mu Gu. Following his victory, he refined the Ocean Heart Flame.
Despite its formidable nature, the Ocean Heart Flame did not significantly increase Xiao Yan’s strength. By that point, he was already at the level of a Two-Star Dou Saint, far beyond the capabilities of that particular flame. While it added to his collection and versatility, its impact on his growth was minimal.
2. Bone Spirit Cold Flame (Ranked 11th)
Next on the list is the Bone Spirit Cold Flame, ranked 11th among the Heavenly Flames. This particular flame held great sentimental value for Xiao Yan as it once belonged to his mentor, Yao Lao (Medicine Elder). After being resurrected and regaining strength up to the Half-Saint level, Yao Lao passed the Bone Spirit Cold Flame on to Xiao Yan.

3. Three Thousand Burning Flame (Ranked 9th)
The Three Thousand Burning Flame was the very first Heavenly Flame that Xiao Yan subdued in the Central Plains, and it remains one of the most fascinating. Ranked 9th on the list, this flame was known for its astonishing regenerative capabilities and its near-immortality. In life-or-death battles, it played a critical role in keeping Xiao Yan alive, healing his injuries rapidly and allowing him to bounce back in situations where survival seemed impossible.
This flame became a cornerstone of Xiao Yan’s survival strategy in many difficult encounters. Its power wasn’t just in destruction — its ability to preserve life made it invaluable. As such, even though it was the first flame he acquired in the Central Plains, it remained one of the most useful and reliable throughout his journey.
4. Purifying Demonic Lotus Flame (Ranked 3rd)
Finally, the most powerful of all the flames Xiao Yan obtained in the Central Plains was the Purifying Demonic Lotus Flame, ranked 3rd on the Heavenly Flame list. This flame originally belonged to the fearsome Demonic Lotus Saint, a peak Nine-Star Dou Saint. To obtain it, Xiao Yan ventured with Xun’er into the treacherous Flame Realm, where the Demonic Lotus Saint personally intervened.

Final Thoughts
Each of the four Heavenly Flames Xiao Yan acquired in the Central Plains contributed in different ways to his journey — some offered raw power, others survival benefits, and a few were key to evolving his unique flame-cultivating technique. However, in terms of rank and influence, the Purifying Demonic Lotus Flame stands at the top, not just due to its power, but because it unlocked the final stage of the Flame Mantra, pushing Xiao Yan toward the peak of cultivation.
From defeating the Soul Palace to evolving his skills into the realm of legends, Xiao Yan’s path through the Central Plains is a testament to determination, loyalty, and the burning will to rise above all odds.
