Naruto: I Can Upgrade My Techniques Infinitely - Chapter 43: The Shinobi World’s Strange Love Polygon

A hundred thousand years ago, there was a great war between cultivators. Immortals fell by the tens of thousands, the path of cultivation itself was severed, and after the dust settled, tombs forested the world.

A hundred thousand years after the last legend faded, Lu Yun, commandant of tomb raiders, descends upon the world. Armed with the Book of Life and Death, he has some burning questions to answer.

……

“This isn’t how you raid a tomb!” Lu Yun smirked at the cultivators frantically scurrying about the ancient tomb. “Do you want me to teach you?”

……

But ah, can someone teach him how to cure his new body’s erectile dysfunction?

Waking up in the body of a 6-year-old boy a few years before Cintra is destroyed, Madara receives a system that gives him the ability to gain the powers of Uchiha Madara.[The peak of Uchiha Madara's system is before he becomes the ten-tails jinchuuriki.]The system's percentage does not stop Madara's power, but rather the system's release. After all, I don't want to see a character who goes around killing everyone from the beginning of the story.

Trying to drown her sorrow with alcohol after her boyfriend hooked up with her sister, Ning Qing ran into the rich and powerful Lu Shaoming in a bar. “I need a wife,” Lu said, and the two got their marriage license.

Soon, she who became a pop star won many pretty boys’ hearts. Singlehandedly, he got rid of all her potential flings and acted innocent. Ning Qing bristled, “Lu Shaoming, what happened to staying out of each other’s private life which we talked about?” Turning the light out, he came over her and whispered, “Now our priority is to make a baby.”

Growing up parentless, Shi Yan, who was left with a large inheritance money, bore a general disinterest in life.

The only times he felt alive was when adrenaline coursed thorough his veins. He quickly found that extreme sports, bungyjumping, cave diving & skydiving, gave him the biggest kicks. The bigger the adrenaline kick, the closer he was to death, the more alive he felt.

Waking up in a pile of dead bodies in an unknown land, after a diving adventure had ended disastrously, he quickly realizes the body he now possessed was not his own.

Follow Shi Yan as he explores this new world where danger lurks around every corner, and death is only a breath away; a world in which Shi Yan could not feel any more alive.
