My Daily Life Clearing Dungeons with a Border Collie

In his previous life, Gu Xi was tricked by a coworker, losing both the woman and the money. He not only handed over a project he'd spent more than half a month planning, but also got pranked maliciously during a livestream by his favorite streamer that night. Furious, he dropped dead on the spot. He'd thought, fine, if he was dead, he was dead. This screwed-up life wasn't worth living anyway. Better to start over. But Heaven wouldn't let him start over! When he woke again, Gu Xi found himself in a space that was white as far as the eye could see. A mechanical voice claiming to be the Wealthy Cashback System told him this place existed outside the Three Realms, and there was no way back. The only way out was to complete missions and earn points to exchange for a body in the real world. Otherwise, he would be trapped here for the rest of his life, forever barred from reincarnation. Gu Xi: What? Go to hell! He'd finally gotten a chance at a new life, only to be dragged to this godforsaken place. He might as well die. Besides, he'd already died once. What was there left to fear? So he stopped holding back and became bold and unrestrained, facing every challenge with an attitude of “if you don't like it, come fight me.” His life motto was: “If you've got the guts, kill me. Otherwise, I'll kill you.” With his wild ways, he ruled the System. Human or ghost, everyone gave him a wide berth. The resentment of a former office drone was more than most people could handle. Even the System had to show him plenty of respect. * Gu Xi slaughtered his way through every instance, unstoppable and loving every minute of it. Then, in one instance, he came across a heterochromatic merle Border Collie that had been abandoned. The puppy was so gorgeous that Gu Xi fell for it at first sight. Ignoring everyone's objections, he immediately took it in and named it Ross. The upside was that he'd have company when entering instances. The downside was that, ever since he started raising the dog, mysterious marks kept appearing on his body... The two of them became companions, one person and one dog, fighting their way through every challenge in the instances. But once Gu Xi's points reached the cap, he could no longer enter any more instances, leaving him with a choice: Stay in the System until the seas run dry and the rocks crumble, or exchange his points for a body and return to reality. Gu Xi hesitated... With his current points, he could surely return and live a comfortable, worry-free life. But what would happen to the puppy? He had no one waiting for him outside, but inside there was a puppy that couldn't look after itself. Gu Xi didn't hesitate: he refused. Until one day, he saw a person and a dog standing beyond the portal of light... It was his favorite streamer and the puppy. * Lu Bei is the creator of the Wealthy Cashback System. Aside from maintaining the System's programs, he especially enjoys lying around in sunny instances. One day, while he was sunbathing in an instance in the form of a merle Border Collie, a challenger showed up and carried him off without a word, then gave him the ridiculous name “Ross.” Lu Bei: What kind of name is “Ross”? I might as well be a shellfish! And so he followed the man around, personally experiencing the instances he'd created himself. Lu Bei thought it wasn't so bad. It was like going undercover on the front lines. But who could have imagined that this pervert would keep smearing drool all over his face, messing up the fur he'd carefully groomed? So, in the spirit of returning the favor, Lu Bei slobbered all over him too. As time passed, Lu Bei realized something was wrong... Weren't they just supposed to be slobbering on each other? Why couldn't he stop turning human and giving him hickey-like marks? Theme: Beware of scams
