Waste Guide? the Top Sentry Is Willing to Serve as a Subordinate

[Future + Interstellar + Whistle + 1v1 + Double Power] Because he failed in his mission and was killed, Si Yi traveled to a strange interstellar world. Fortunately: she still retains strong fighting skills and fighting abilities. The unfortunate thing is: she is a guide, but her mental power is still the lowest level F. As an F-level guide, her fate is to be trafficked and become a breeding machine. The desperate choice was to agree to the deal with SSS-level sentinel Yan Lin and bind the contract. He gave her a new identity and protection, and even made an exception to make her the first F-class guide in history to join the interstellar special forces. And she has to play the role of "Si Yi" and steal the Si family's genetic research results for him. They use each other and have to rely on each other closely. Walk through the snowy mountains besieged by the infected, climb over the cliffs full of corrosive plants, and break through the sea of ​​corpses. Si Yi wants to climb to a higher position, and Yan Lin wants to change the rules of the world. When the lies carefully woven by the Si family were peeled away, a secret that could subvert the world was exposed. The guide's mental power could have surpassed the sentry and controlled everything. "Did you know? The guide can actually control the sentry's mental power at will." "Really? What will be the result if we do that?" "That will be your most loyal slave."
