I'm looking for a novel. Everyone, help me!

Many years ago (about seven or eight years ago), I once read a serial novel in a book. Due to the passage of time, I can't remember the name of the novel. Although I only read one issue of the novel, I found it very interesting and still can't forget it. I've searched online before, but I couldn't find it! I'll describe the content of the serial I read. Take a closer look. The novel depicted an illusory era. There seemed to be the Nine Provinces and the Great Wilderness (also seemed to be the "Cloud Wilderness", but he couldn't remember clearly. He didn't know what "Wilderness" was, so he would call it the Great Wilderness for the time being). The Nine Regions is like our Jiangnan. It is rich in resources and has a large population. It is very suitable for living. However, the Great Desolate has a steep terrain, a changeable climate, and an abnormal environment. It is a desolate and dangerous land. However, there were many rare treasures among them. Many people would often gather in groups and travel across mountains and rivers to search for treasures in the vast wilderness. Once they found one or two, they would become rich for a while. However, although the treasures were tempting, the dangers and dangers were enough to make most people shrink back. A group of people (some of them were outlaws who had fled to the ends of the earth, some of them had spent all their money on treasure hunting in the Great Wilderness, and of course, some of them were forced by their lives or had to raise money for their families to treat their illnesses) traveled through mountains and rivers and passed through a primitive forest. This forest was dense and unusually dense. It seemed quiet and peaceful, but it also gave people a sense of evil. Suddenly, everyone found a huge snake as thick as a tree trunk. After killing it together, one of them found that the snake looked particularly awkward. After some observation, he found that the snake's abdomen was much larger than the snake's body. Curious, he cut it open and found a slightly corroded corpse. It turned out to be a person who had unfortunately been eaten by the snake. When everyone saw this, they felt their hair stand on end. However, the charm of the rare treasure gave them the courage to continue moving forward. At night, they encountered a large swamp. The area was especially large, and there was no wooden bridge to cross. For a moment, everyone was in a dilemma. The night was getting deeper and deeper. Just as everyone was hesitating to move forward, a strange song sounded from the other side of the swamp. Everyone carefully examined it, but they couldn't hear what it was. At this time, an older person in the crowd came to the front of the crowd and sang loudly in the same strange language across the swamp. He echoed the song on the other side and agreed with each other. After a long time, the singing on the other side stopped. A rope was thrown from the other side. The old man told everyone that there was a Miao tribe on the other side of the swamp. The people there were rather strange. He had sung to them just now to explain the situation to them. Courtesy should be returned. Thus, everyone climbed the rope to the other side of the swamp. As expected, they found a Miao village. However, what was strange was that the entire village was quiet, so quiet that it was a little abnormal. After searching for a while, they found that there was no one in the entire village. Everyone decided to rest in one of the houses. At this moment, someone found a cabinet in the room. When he opened it, there was something inside.(Hehe, I forgot what it was. I'll use "thing" to replace it for now. Sorry.) He reached out to take it. Someone shouted to stop him, but it was too late. As soon as the person's hand touched the thing, he howled in pain. His whole body was bleeding as if it was pierced by thousands of needles. What was even stranger was that everyone who was splashed by his blood was also screaming in pain. It turned out that that thing had been poisoned! Hehe, it seemed like this was it. My writing style is not very good, so I might not be able to describe it in detail. If there are any ambiguities, I hope that everyone will not laugh at me!
