As an Ordinary Person, How Do I Redeem My Dragon-Blooded Big Brother [Quick Transmigration]?

"My dear, the contract we initially signed did not state that it wouldn't include fantasy-type worlds."

The system's sweet voice rang out, causing Tang Lingnan to clench her fists even harder, her face distorted with rage. After taking a few deep breaths, she squeezed out a few words through gritted teeth.

"I remember the contract clearly stated an easy novice world as the first one! Is this what you call easy?!"

If the system had a physical form, Tang Lingnan would have bagged it and beaten it a thousand times. Now, she could only insult its ancestors with humiliation, regretting her youthful ignorance in falling into the system's big trap.

"My dear, you have two minutes left on the call. I suggest you don't dwell too much on this minor issue."

Tang Lingnan grew even more furious, but for the sake of the mission, she could only swallow her anger. Damn it! This is simply too much bullying!

Tang Lingnan, who unfortunately died at the young age of twenty, had to sign an unequal treaty with the "Redeem the Dragon-Blooded Brother" system in order to revive, doing free labor for the system in various worlds.

"So, what does a powerful, arrogant male lead (Long Aotian) need redeeming? He's successful, surrounded by beauties—what could he possibly be dissatisfied with?" Tang Lingnan, a commoner, loathed this kind of humblebragging behavior and wished she could take his place.
