Zhou Wen was a spatial expert, so it wasn't difficult for him to understand the content and annotations. Although Zhou Wen already knew a lot of the content, there were indeed some unique points that gave him many thoughts and ideas.
Based on the content, the person who wrote it had to be an existence with extremely high attainments in space. Only then could they stand at a high vantage point to explain certain problems.
Leng Zongzheng's annotations were also very precise. Furthermore, he had written quite a number of his understanding and insights into spatial powers. It was quite an inspiration to Zhou Wen.
Combining his insights and experience, Absolute Space broke through to the Terror grade in just a few hours. Furthermore, it was constantly improving.
Although he didn't know if he could really break through to the Calamity grade, the speed at which he improved was already rather shocking.
