Simulate To Survive And Hopefully Reach Immortality [Isekai Xianxia]

The cultivation world is harsh and treacherous. And it's not just because people keep saying the same thing to convince you that it is. At the tender age of four, just a few years into his reincarnated life, Nie Huangxie found his clan massacred by a mysterious group of demonic cultivators. Luckily, his family and loyalists managed to slip away to a new county and start anew with whatever they had left. It took another three years for things to finally get better. And for the future of his family, he had to carry the pressure of becoming a disciple of a low-tier immortal cultivation sect at eight years old, while his brothers and sister could chase whatever passions they had. For the next seven years, his days started with racking his brain to get more resources and ended with sleeping on an itchy, insect-infested mat while enduring the aches deep in his bones. But things took an unexpectedly sweet turn after Huangxie found out he had somehow obtained a simulation system. Though not as strong as the ones he had read about back on Earth, at least he now had a golden finger to help him. Or so he thought... He kept dying prematurely in every simulation attempt, no matter what he tried. However, after his 30th attempt, he unlocked a new feature: Team Simulation. With this feature, he could invite other people to simulate and reap a large fraction of their rewards? It seems like this feature is the only way out for Huangxie in the foreseeable future. Whether it's actually a good or bad decision to use this feature remains unknown to him. But hey, high risk, high reward. He just wants to survive. And maybe... hopefully, reach immortality someday. [A/N: No harem, and all characters are proportionately competent/smart in their context.]
