The more Yu Wudi fought, the more apprehensive he became.
'What's going on?'
It wasn't like he hadn't ingested Crimson Demonic Earth before. How could he not know about the duration of its effects? He had already struggled through his window of inability to ingest Crimson Demonic Earth, yet Ling Han was still going on as incredibly strong as before? This made absolutely no sense!
Perhaps Ling Han had ingested Supreme Crimson Demonic Earth? Strengthened Crimson Demonic Earth?
Right now, Yu Wudi could only hold firm on his belief that he had ingested the Crimson Demonic Earth later, so his battle prowess would definitely decline slower than Ling Han's. That being the case, he would definitely have the last laugh.
