Death March kara Hajimaru Isekai Kyusoukyoku (WN) - Volume 17 Chapter 34

Pain, Pain, Go Away is a novel by Sugaru Miaki, also known as Fafoo, author of Starting Over and Three Days of Happiness. Unlike Miaki’s previous two books, Pain, Pain, Go Away is not a rewrite of any story posted to 2ch, but an entirely original one.

The plot involves a young man who becomes a killer (by accident) – but his victim has the power of “postponement,” temporarily delaying her death.

“Let's get married!” When those words came out of the beautiful CEO's mouth, Li Chen felt dizzy!

The boundless universe is full of many wonders.

I, Chen Ping, only have one sword!

I can move mountains, overturn the seas upside down, suppress demons, slap the face of gods, pluck the stars, break rivers, destroy cities, and… open the heavenly abode!

The Midland world was full of wonders.

In the center of the world, there was a scholar who had once used a sword to slash out a waterfall of the Milky Way. This was the person he was the most proud of.

At the edge of East Sea’s cliffs, there was a nameless Daoist who was unwilling to ascend to the peak of a mountain. He only wished for a cool breeze to brush against his face.

In the Western Pure Land, there was an old monk who liked to treat people to chicken soup and tell stories.

In the southern border of the Wilderness, there was a blind painter who controlled golden-armored puppets that were as tall as mountains to move the hundred thousand mountains, creating an embroidered picture.

A impoverished youth who grew up in the north. One day, he saw tens of thousands of Sword Kinesis Immortals above him, like a swarm of locusts crossing the border.

He wanted to see for himself the scholar that the storyteller had mentioned, the surging tides of the East Sea, the vast swamps of sand in the west, and the majestic mountains of the Southern Wasteland.

Thus, one day, the youth picked up the wooden sword and began to descend south.
