Upon hearing Sun Wukong's words, which seemed tinged with pity, Li Jing couldn't help but seethe with rage inside. How dare he mention Nezha? How could he still bring up Nezha?
Boundless fury almost made Li Jing lose his reason, but though he managed to suppress his anger at the last moment, it also led him to abandon all regard for his life. Originally golden, the talismans had now all turned blood-red in color, for Li Jing was burning both his life-bound essence blood and his cultivation on the half-step Great Path.
It could be said that this was Li Jing's strike of certain death.
Sun Wukong could have easily dodged this attack, for after this strike, even if Li Jing didn't die, he would likely be left a broken man, his fate—to kill or to maim—at Sun Wukong's discretion.
But Sun Wukong did not do so. Because he respected Nezha, he would not evade Li Jing's sacrificial strike, even if it meant his own demise.
