The powerful being by Zhunnti's side was someone Zhunnti had met halfway along the journey. He was also a primordial divine being, though his origins were somewhat humble!
Daoist Landeng was also a creature of the West. His true form was the very first spirit coffin in Honghuang, and his Daoist sanctuary was Mount Lingjiu in the West, possessing the cultivation of a peak Taiyi Golden Immortal.
Zhunnti happened to travel alongside Daoist Landeng, and naturally, they ended up being the last two to arrive.
