Leguna. An orphan. His life changed dramatically the day the thieves’ guild happened to select him for training and development. He would go on to become lifelong friends with a loyal mercenary, the partner of a beautiful magus who was cold as ice, the savior of a mysterious disfigured dark-elf girl with a talent for the Breath, and the unlikely caregiver for a feisty young maiden. And yet, who would be with him to the very end?

Reincarnated as the first prince of the Jing Dynasty, Jiang Changsheng was transferred by a traitor as soon as he was born, and then he was sent to a temple to become an ordinary little Taoist priest.

From the prince to the little Taoist priest who no one cares about, his life has fallen. Fortunately, Jiang Changsheng has activated the survival system and has an infinite lifespan. As long as he survives the hardships of life, he can get a survival reward.

He was almost killed by his brother while practicing martial arts, but survived by luck and got the leg of the gods.

Encountered an earthquake, was nearly killed by the beam of the house, and obtained the Nine Searching Heavenly Dragon Step.

The demons roamed the capital, passed it safely, and obtained the magic weapon to conquer the demon pestle.

- Description from novelbuddy

Yang Feng somehow transmigrated into a different world and received a legacy of an ‘ancient high tech’ family, which does not directly raise his power, but gives him the technology to build things which are way more advanced than the seemingly medieval world.

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.
