Deadly Infiltration

During an international bidding process, the core parameters of the "Tianxuan" project under Huguang Province Guotong Group's Star Shield initiative were mysteriously leaked.

Behind the enormous losses lay a hidden wound torn open within the group.

Liu Jiang, head of the Investigation Division at the Provincial State Security Bureau, was ordered into action and teamed up with Xiao Jin, head of the group's Confidentiality Division.

As the investigation deepened, they discovered that this was no simple case of commercial espionage. A deeply concealed current of foreign forces was quietly infiltrating the group by exploiting the hidden cracks in human nature.

A rising technical talent just back from studying abroad, a key technician suddenly plunged into hardship, a disillusioned middle manager, a high-ranking technical authority, a cautious leadership secretary, seemingly ordinary cleaning staff... Each seemed to be dragged into a vast web by an invisible hand.

As the investigation neared its core, Xiao Jin was shocked to discover that the clues pointed to the most familiar corner of her own life.

When family ties collide with national law, and personal grudges spark a crisis, Xiao Jin must make a choice on the precipice between national security and personal feelings.

This war without gunfire has never been so close to everyone's daily life.

Beneath the tranquil surface, who is the true "Shieldbreaker"?

And who can build that final, unbreakable line of defense?
