Ace Agent: Undercover in Republican-Era China

Traveling through the Republic of China, Zhang Lin became the first in Huangpu's thirteenth period and a disciple of the emperor. After graduation, he gave up his ace unit and was sent to the predecessor of the military command by a transfer order, becoming a "secret agent" that everyone despised. My classmates ridicule me, my colleagues ostracize me, and my boss is still an ineffective teammate. It was a dead end at the beginning, and the mission was about to fail, and he would be blamed. Zhang Lin smiled. Bite! The Ace Agent system is activated! Micro-expression analysis, perfect disguise, memory soul search... Countless magical skills are added! He shocked the entire team with his unique portrait skills, and even made a comeback in a desperate situation, captured the spy team leader alive, captured the secret code, and became famous in Jinling! Zheng Yaoxian regards him as a strong rival, and Boss Dai regards him as a trump card. And Zhang Lin's goal is far beyond that. Using his past life memory and system capabilities, he was able to maneuver his way up the ranks within the military system and rose through the ranks. He wants to weave a dragnet of his own in the darkest hour before dawn, and become the sharpest knife to pierce the enemy!
