顿弱 / Dun Ruo
顿弱 / Dun Ruo enters the wiki through 《资治通鉴·秦纪》113｜李牧如何用一己之力阻秦国统一 as a 秦国 intelligence actor operating against 赵国 during Zhao’s disaster and famine crisis. The source says he uses heavy money to buy Zhao people into spreading rumors and helps create an ominous sign involving white hair or white growth appearing from the ground.
The episode’s role for Dun Ruo is strategic, not biographical. He shows Qin using disaster-exploiting timing and information warfare before the 229 BCE military attack. The same source then describes a Qin bribery operation through 郭开 against 李牧 and 司马尚, keeping Dun Ruo inside the broader Qin pattern of weakening Zhao’s morale and command trust without treating every later spy action as personally attributable to him.
