After listening to Li Yinzhu calling Song Shuhang as ‘Ah Song’, Scarlet Firmament Sword decided to give Scarlet Firmament as pet name too. ‘Scarlet’ wasn’t appropriate since it feels like a cursing, so ‘Firmament’ was chosen.
Way of Eternal Life Being
An overwhelming majority of the practitioners in All Heavens and Myriad Realms practiced to become the Heavenly Way and forge their own imperishable legends. It was especially so for those Eternal Life Beings who had stepped on their ‘Way’. After all, they’d already achieved eternal life, and as they continued to advance, the only thing that remained was ‘imperishable, Heavenly Way’. 
But Dao Priest Scarlet Firmament was different. After he stepped on his ‘Way’, his goal became to ‘cultivate’ the next Heavenly Way. Even his ‘Way’ was related to this goal.
Tribulation Immortals and Eternal Life Beings in All Heavens and Myriad Realms had already gotten a vague feeling—there appeared a deficiency in the Current Heaven, and various signs indicated that it was about to disappear.
Planting A Scallion
500 years ago, Scarlet Firmament had a hunch that a scallion he was about to cook would be the next Heavenly Way. He planted the scallion in a place with rich spirit energy.

Collapse of the Heavenly Way
- “Sowing fate, forming fate … «Flame Sabre» is a fate, scallion monster is a fate, Li Tiansu is a fate and Li Yinzhu is also a fate.„
Back then, when he taught his disciple Li Tiansu sword techniques, Scarlet Firmament had inadvertently noticed the existence of Song Shuhang. With kind intentions, he taught Song Shuhang a basic style of the «Heaven Scorching Flame Sabre», which planted a seed of fate.
Even he had not expected that in the future, the scallion monster that he’d planted and his nominal disciple, Li Tiansu, would meet Song Shuhang one after the other, allowing him to grow the fate that he sowed at that time.
It was as if there was a large and invisible hand between heaven and earth that had pulled him and Song Shuhang together, causing two people of different ages to become deeply tied to one another through various occasions.
