In 2050, the epoch-making project "Lingxiao Project" (Sky Elevator) of the Eastern Republic's "Cloud Rail Group" is approaching a breakthrough and has become a thorn in the side of the overseas military giant "Deep Blue Alliance". The spy leader "Albatross" (Zan Tianyu) launched "Operation Broken Chain" and sent elite soldiers and generals to sneak in and steal secrets.
Li Feng, the elite security guard at Yungui, was ordered to take action in the face of danger. With his extraordinary insight and iron-blooded skills, he saw through the disguise, and with the assistance of the group's researcher Qi Wei, he started a 60-day life-and-death race with the spies. The enemy is in the dark and we are in the clear, and there are many traps: data fraud, fatal blame, psychological manipulation, and even the high-level ghost "Bodhizi" has surfaced. Li Feng used his brainpower as a blade to peel off the cocoons in thrilling reversals and fight without mercy at close quarters.
As the spy network was torn apart layer by layer, Deep Blue actually planned to destroy "Ling Xiao". Li Feng and Qi Wei fought for life and death, and at the last moment killed the "Albatross" on the top of Guyu Mountain. Before the base's shocking countdown, they relied on their ultimate reasoning about human nature to crack the code of destruction. The ladder to heaven is finally completed, but the undercurrent continues, and the guardian still stands at the junction of light and shadow.
