“I suddenly discovered that this world is dangerous today.” Bai Zhi looked grave as he typed out a line of text on his computer.

“When I went out today, I came across some poor guy getting bitten by another person. Luckily, a few brave guys rushed out to bring the criminal to justice, but when the person who was bitten struggled to stand up, he was immediately beaten to the ground by one of those who had supposedly saved him—and then, they called the police! I’ve watched more than enough modern movies to know what happened. The zombie was taken out before the virus could spread.”

“Last time, you told us about a few guys saving humanity from an alien invasion… This time, it’s a zombie outbreak?”

There was an exasperated response from the chat box.

“So how was that dangerous?”

“There are also several girls who are fighting tooth and nail for a piece of me! It’s totally Hell in here, don’t you think it’s dangerous!?”

“???”

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.

The spiritual energy recovers, others practice, and Xu Bai upgrades.

After getting the game system, because I haven’t received the main mission, I frantically spent 22 years of experience points.

Then……

Xu Bai suddenly discovered that he was already invincible.

Practice exercises.

Full skill.

Everyone: “Why don’t you have a bottleneck.”

Xu Bai spread his hands: “What’s the bottleneck, click to upgrade, isn’t it enough?”
