Lu Zheng transmigrated to a dangerous cultivation world and became a minor cultivator who had been scared to death. Too afraid to go out and hunt demons or fight anyone, he can only hide in a burrow and scrape by.
That is, until he plants spirit herbs and sees a dialogue box above them, along with the treasure chests they are nurturing.
[Feed me nutrients! Give me spiritual energy! I can't grow tall if I have nothing to eat or drink!]
[Because you didn't tend it carefully, your 'Moonwater Grass' is of inferior quality and has only nurtured a Level 1 treasure chest. Harvest it to receive a Level 1 treasure chest.]
He opens the chest.
[You obtained 'one month of cultivation'.]
[You obtained 'Spiritwood Technique'.]
[You obtained 'Insights into the Geng Metal Sword Finger'...]
[You cultivated an 'Innate Gourd Vine' and obtained a Level 10,000 treasure chest...]
[You obtained the 'Indestructible Diamond Body'.]
As he keeps planting, he suddenly realizes that he became an Immortal Emperor ages ago.
