The protagonist Lu Zheng's military nickname is "Lu Yanluo". He kills decisively on the battlefield, and the enemy is frightened by the news. This name represents his ruthlessness and determination in harvesting life and death. But "Yam Luo" is not indiscriminate killing, but judgment. Every stronghold he takes down, every laboratory he blows up, and every piece of evidence he sends to court is a sophisticated and unstoppable trial.
