Spy Back in Time

Thunder pierced the night sky on the outskirts of Yuandu, and a strange black talisman appeared out of thin air on the farmland, becoming the first crack to break the peace. No one knows that this symbol is not only a mark of time and space travel, but also the prelude to a protection across time and space.​ The Allies in the future world are on the verge of crisis. The enemy undercover steals the core unknown energy technology and creates the "Annihilator", a deadly weapon that can annihilate everything. All lives are devastated and the ecology is destroyed. The arts and sciences from the future, carrying the mission of saving the country, use the time travel technology strictly controlled by the state to travel retrograde back to the past.​ The iron law of time and space is clear: you must kill your past self within 72 hours, otherwise you will be swallowed by the power of the universe. But he happened to be an exception - when in the future he met his 29-year-old self who had failed the public examination five times and had life ideals but was deeply confused, his murderous intention turned into a fetter.​ The two "arts and sciences" work side by side, avoiding the pursuit of the enemy's future soldiers and undercover agents, protecting the mentor's technology from being stolen, and looking for salvation in the chaotic gaps of time and space. What secrets does the strange talisman hide? How to crack an undercover network? Can twin souls change the fate of the destruction of their home and country?​ A game across time and space, a two-way redemption with oneself, starting from the strange talisman in the farmland, going against the times, using oneself as a blade, protecting the family and the country, and surviving the catastrophe of time and space.
