MTL - From the Head Pillar Tanjiro, Take Stock of the Wonderful Nicknames of Zongman - Chapter 600

A few hundred years ago, Earth was affected by a mysterious force from the depths of the universe, triggering the revival of spiritual energy. However, things didn’t turn out as wonderful as humanity had imagined. The spiritual energy carried a strange power that caused the corpses of all living things to rise again, transforming into ghouls. And above these ghouls, even more terrifying beings existed…There were no ancient methods of cultivating immortality, nor any legendary awakenings of supernatural powers. But within the spiritual energy, there was also a presence of ghostly energy. This led to the emergence of Runes.Some people bore mountain runes, enabling them to move mountains and overturn seas, suppressing chaos. Others carried river runes, allowing them to reverse the flow of mighty rivers with a mere gesture. However, this process required a special profession to assist these rune cultivators—to constantly modify and engrave their runes, making them more refined and perfect.This profession came to be known as Rune Engraving.

Upon awakening, Lu Xuan found himself as an ordinary spirit plant cultivator, tending to an acre of land merely scraping by in the realm of cultivation.Fortunately, he stumbled upon an unexpected revelation: with each maturing spiritual plant, he received additional rewards.Harvesting a The Firefly Grass yielded a Golden Sword Technique.From the Blood-Devouring Vine, he obtained a Purification Talisman.And the Phantom Spring Flower gifted him a prescription for the elusive Luminous Flame Pill.Henceforth, he contentedly tended to his own spiritual fields, observing the tumultuous tides and shifts in the world of cultivation.“Duels and clashes, expeditions into secret realms, immortal fortunes, obtaining mystical treasures… None of it concerns me!”“I simply wish for peace and quiet to tend to my fields.”

“I'm going out to do something, so I can't take care of you any more. You can go down the mountain and have fun. But if you can't find someone who matches your Innate Pure Yang Body in three years, you're finished!”These were the last words the old man, who was Lionel Yeager's teacher, threw to him before he vanished. Meanwhile, having mastered most of his master's skills, Lionel Yeager went down the mountain and took his first step into civilization for the first time in years.With his unparalleled medical and martial arts, he sets forth on a journey, befriending new allies and crushing all the enemies that stand in his way, as he attempts to resolve his Pure Innate Yang Body constitution, and cultivate to the top of the world!

When a person dies, they either die light as a feather (aka unimportant) or heavy as Mt. Tai (aka very important).
