Pu Qianjun is the commander of the Tiger Roar Army, which serves as the private army of the Eastern Palace under direct command. He is the son of Pu Xiang and has been Wen Ze's study companion since childhood. Pu Qianjun is revealed to be a reborn person who, upon waking, confirmed the time and immediately took his army to search the Sitian Tower, where he found gunpowder hidden in the dungeon something he had failed to find in his previous life. Despite his military position, he displays a straightforward and simple personality, lacking the cunning to deceive Wen Ze. He possesses beast-like keen intuition in command but is otherwise naive. Like his father Pu Xiang, he demonstrates burning loyalty to Wen Ze and knows many of Wen Ze's secrets that even the Emperor and Empress are unaware of. When Wen Ze asked him if he was reborn, Pu Qianjun was astonished and spoke his thoughts aloud.
