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.”

An ordinary medical student suddenly got the blessing of the system and could directly see the patient’s health! Since then, treating illnesses and saving lives has become commonplace, and he has also become a legend in the medical field.

Kyoukai Senjou no Horizon chronicles the story of a futuristic civilization returned to Earth after constant warfare hindered them from traveling beyond the post-Apocalyptic Earth. At this stage, a small archipelago called the Divine States were the only hospitable land on Earth. In order to regain the space-faring technology they had lost after many years of war, they decided to recreate history with a book called the Testament as a guide.

It is the year 1648 in the Testament Era. Toori Aoi, Chancellor and Student Council President of the only academy on the airborne city-ship Musashi, faces the ten-year anniversary of the death of his childhood friend Horizon Ariadust in an accident. As he prepares to celebrate the occasion by proposing to P-01s (an automaton who looks exactly like Horizon) he discovers that his suspicion about P-01s’ appearance actually has a basis in truth; P-01s is in fact Horizon Ariadust, reborn into a robotic body. In addition to this, Horizon’s emotions had been stripped away and are now stored in eight powerful weapons called the Mortal Sin Armaments; which are now in the possession of key people in various established countries in the Divine States.

To retrieve the emotions of Horizon Ariadust, Toori Aoi along with his friends and allies begins a crusade against different obstacles as key events in history are recreated in a futuristic manner.
