While other cultivators expected Li Shiming to encounter the most trouble, it turned out to be the easiest for him.
Li Shiming needed to merge five grotto heavens. If he were still cultivating using 'Chaos Energy', merging these grotto heavens would indeed be difficult, but now he's cultivating 'Immortal Energy', making the merger astonishingly smooth.
Nevertheless, he adhered to Yin Shilan's pace for merging, ensuring that his progress did not surpass hers.
Despite Yin Shilan's lack of talent, her grotto heaven was much stronger than those of other Great Immortal Envoys, and the energy output from her grotto heaven was over a hundred times greater than that of a normal Great Immortal Envoy.
To prevent any issues during her merger of the grotto heavens, Li Shiming had her enter a simulation projected by IBMz15 to simulate the merging process.
Therefore, the pace at which Yin Shilan merged the grotto heavens was nearly equivalent to Li Yuanba and Li Taibai.
