As soon as the Fuso tree spoke, Jiang Hao's face turned dark. It's said that you shouldn't hit a person's face or expose their shortcomings, yet the Fusang tree was deliberately revealing Jiang Hao's weaknesses.
When Di Jun was born, the top-level Innate Spiritual Treasure, Hetu Luoshu, came into existence. When Taiyi was born, the Chaos Bell, a treasure from the dawn, was there by his side. When the Dongwang Gong was born, the apex Innate Spiritual Treasure, Jingyang Bell, was his companion.
Even the Flame Emperor, upon becoming the new Sun God in the prehistoric world, felt a connection with the Sun Star, which evolved an ultimate Innate Spiritual Treasure, the Great Sun Bell, as a gift for him.
Yet Jiang Hao alone, after the Flame Emperor's abdication, though he inherited the title of the Sun God, he never really gained the recognition of the Sun Star.
