The Myriad Worlds + farming + pocket dimension + immortality + trade between worlds.
After transmigrating to an Immortal Martial World, Lin Chen gets a Building Upgrade System. He farms, raises chickens and keeps fish, all while focusing on staying safe and steadily growing stronger.
He munches on ten-thousand-year-old spirit herbs like radishes, snacks on thousand-year-old vermilion fruits, keeps a nine-heavens divine dragon as a guard dog, and even has an Immortal Emperor come to him to buy immortal medicine wholesale...
Then one day, a foreign land's Ghost Law Ruler tears through the void and descends upon this world with murderous intent. Lin Chen slowly opens his eyes, yawns, and kicks the big rooster lying at his feet.
"Dahua, get up. Time to work!"
