The God of Underworld - Chapter 100 - 54:

In this world, orphans or just anyone without any hope for this world can apply to become a “walking target”. Their sole purpose is to be a practicing dummy for the students of the sect who train to become “Demon Hunters”. These students need “walking targets” to test their training on living, walking beings of flesh and blood.
In exchange, they will be provided with food & shelter.
Their existence value is lower than a slave, but if they manage to survive a few years they can receive a life long pension.

Xiao Han is such a “walking target”. One time he witnessed a powerful Demon Hunter disposing a demon. When the demon died, a fragment of the demon that managed to escape entered Xiao Han’s heart. No one saw that, and even Xiao Han himself only felt some discomfort for an instant.

But that thing in his heart soon gave Xiao Han visions, and the first one is of a cultivation method which allows Xiao Han to absorb damage to enhance his body. A perfect cultivation method for a “walking target”.

- Description from Novelupdates

15 years ago the world discovered magic as well as mythical beings (basically beings from various legends) in another dimension. Humankind learned to summon these dangerous mythical beings and use their power to great effect. Seven countries formed contracts with these “mythical beings” and gained their allegiance as a result. The mythical beings will choose their summoners on their 14th birthday and give them a stigma. Schools have been set up to train summoners and magical swordsman (basically bodyguards that give the summoners time to cast their spell) as a result.

15 years later after the finding of magic Kazuki Hayashizaki is chosen as a summoner and given a stigma to indicate that. This is surprising since males aren’t chosen as summoners due to their low amount of mana compared to females. As the first male to be a summoner Kazuki is under a lot of scrutiny by almost everyone.

To complicate matters his sister (who’s a magical swordsman) is against him going into summoner school to train there as a summoner. Because summoners and magical swordsman have a cat mouse thing going on where summoners look down on magical swordsman as inferior so his sister naturally is against him going there. She’ll stop him even if it means going to war.

Kazuki however is determined to thrive in summoner school and has already determined to give it his all. Even if he’s the lowest ranked student (ranked E) and his fellow students intend to demean him he’ll prove himself as the strongest summoner.

Jian Huan found herself transported into a xianxia novel as the fiancee of the main antagonist.Feeling her empty wallet, she recalled the pitiful fate of the original owner of the body who stubbornly refused to annul the marriage. Without hesitation, she took the marriage contract and went to the antagonist for a friendly negotiation.At this moment, Shen Jizhi, the future scourge of the cultivation world, was still a righteous disciple. He silently looked at the marriage contract with a cold expression, asking, “How can I get you to annul this marriage?”“One hundred thousand spirit stones,” Jian Huan held up ten fingers, “as long as you pay one hundred thousand spirit stones, our marriage will be void.”Shen Jizhi fell into silence for a moment. “Is there nothing else you want me to do?”Jian Huan shook her head. “None.”Shen Jizhi asked sternly, “You will only accept this condition?”Without hesitation, Jian Huan replied, “Yes.”Shen Jizhi’s tone turned harsh. “Then there’s no annulment.”Jian Huan was confused. “?”Shen Jizhi looked at her and said, “I won’t annul the marriage. We can get married whenever you want.”He bid farewell. “I have other matters to attend to. Goodbye.”Jian Huan exclaimed, “???”
