On this occasion, as Zhou Tian had specific goals and just so happened to possess the necessary strength, he was able to exercise a certain level of agency prior to entering the Ancient Ruins Space.
When he felt the force attempting to pull him into the Ancient Ruins Space after entering the Spatial Passage, he immediately began resisting with all his might. Despite Zhou Tian's resistance, the pulling force remained unaffected and even appeared to pull him in deeper. However, due to Zhou Tian's resistance, his speed towards the Ancient Ruins Space notably decreased at that moment.
Under normal circumstances, once he entered the Spatial Passage, Zhou Tian would be teleported into the Ancient Ruins Space in a blink of an eye. But with his resistance, his speed significantly decreased. In the end, Zhou Tian maintained some mobility even as he was persistently pulled into the Ancient Ruins Space.
