Time Travel? Start by Swallowing the Way of Heaven

Gu Yuan traveled to a protector. He planned to start a new life like this, but he didn't want to be a protector of heaven. This Tiandao was hunted as prey by other Tiandao and was seriously injured. The original protector tried his best to save her but missed the best opportunity to heal herself and unfortunately passed away. Gu Yuan, who had just arrived, originally wanted to fulfill the original owner's last wish and save Tiandao, but an idea came to his mind. "She found you occupying the magpie's nest, how can you still survive?" Gu Yuan, who woke up, slowly stretched his hand towards the origin of the way of heaven. "By devouring her origin, you will have no worries and will become stronger." The humanity in Gu Yuan's heart is fighting against the devil. How should he choose?
