It's Just the Lord of Extermination, It's Not Like He Hasn't Been Killed Before

[Collapse Star Railway, no system, no CP for the protagonist, original male protagonist, humorous style, dense content, try to make the character seriously ill without being OOC] After the Battle of Hu Lei, Lord Annihilation's intention to destroy our Immortal Zhou has become as serious as Sima Zhao's. Everyone knows that as an immortal boat with strong martial virtues, in line with the principle of Emperor Gong Si Ming to "take life and death lightly, and do it if you don't accept it", he hunted for the sharpest arrows - General Fei Xiao of Tianshui immediately decided to go out with Qingqiu soldiers to kill at least one Lord of Annihilation. At this time, a young man stopped her and said that the general was not allowed to start a war. He alone was enough, but as the Lord of Destruction, there was no way anyone could match him. The young man said: "It's very simple. I am the Lord of Destruction." After saying that, his aura was no longer concealed, and it was revealed that he was also the Hunting Order. The young man turned around and left, leaving only a back figure and an earth-shattering word—— "It's just the Lord of Extermination, it's not like I haven't killed him before." Ps: This book actually started writing in version 2.3. Due to some reasons, it was delayed until now, so some of the stories will be slightly different from the original version. This is inevitable now and in the future. I will try my best to stick to the original work.
