Li Wudi had an expression of surprise on seeing the Green Earth Flame, his face twisted a bit but he was back to normal in little time. This Green Thunder Lord was unpredictable and he had an etch of weirdness about him. So it was a bit normal to expect that he could incorporate Green Origin Thunder and Green Earth Flame into his battle technique.
Though he hated to admit it, he was not a worthy competitor for the Green Thunder Lord. But as long as he could stall enough time by bombarding him and getting the cultivators on his side to collectively attack as well, they should be able to land a few deathly blows on him as well.
Next, Li Wudi drew his blade forward. He calmly ripped an opening in the curtain like barrier of the Arch Killer. Of course, by the time he stepped out, he had a strong and intimidating war might. The trails of someone who was poisoned couldn't be seen.
