Four Spirits Profound Astral Formation, a High-Profound Tier formation Dou Technique. Su Heng had used it to kill Mo Cheng, the head of the Mo Family.
As Su Heng's primary Dou Technique, he had been constantly considering how to make the Four Spirits Formation even stronger ever since his battle with Mo Cheng.
In the memories of his previous life, the Four Divine Beasts were the Azure Dragon, White Tiger, Vermilion Bird, and Black Tortoise.
They were both the Four Divine Beasts and the Four Sacred Beasts, the four spirits of heaven and the most powerful beings among divine beasts.
Moreover, the Four Spirits Profound Astral Formation was powered by four different attributes of Dou Qi. Thus, Su Heng had always wondered whether he could transform his four flame magical beasts into the even more powerful Four Sacred Beasts.
Or perhaps the Four Spirits Profound Astral Formation itself had originated from the Four Divine Beasts?
In the ancient texts Su Heng could find at the Alchemist Guild, he had never seen any records concerning the Azure Dragon, White Tiger, Vermilion Bird, or Black Tortoise.
On the Dou Qi Continent, the strongest dragon-type magical beast was the Ancient Void Dragon, while the strongest bird-type magical beast was the Ancient Heavenly Phoenix.
But just because the Dou Qi Continent did not have them did not mean the Great Thousand World did not!
Su Heng even vaguely remembered that the Great Thousand World possessed the four great sacred beasts: the Azure Dragon, White Tiger, Vermilion Bird, and Black Tortoise!
In other words, the Four Spirits Profound Astral Formation might have dated back to ancient times. It could have been some formation Dou Technique inherited from the Four Sacred Beasts, only to be worn down into fragments by endless ages.
