Valkyrie's Shadow - Chapter 11Before the Storm: Act 2,

Ning Shu had dropped dead. But in a burst of good fortune she became a task-taker in charge of counterattacking for pitiful cannon fodder. Thus, Ning Shu, in one world after another, took all kinds of life roles, encountered all kinds of ‘you’re heartless, you’re ruthless, you’re making trouble for no reason’ people. She encountered all sorts of white lotus flowers, green tea b*tches, scheming b*tches, by the batch.

Growing up in poverty, Sunny never expected anything good from life. However, even he did not anticipate being chosen by the Nightmare Spell and becoming one of the Awakened - an elite group of people gifted with supernatural powers. Transported into a ruined magical world, he found himself facing against terrible monsters - and other Awakened - in a deadly battle of survival.
What's worse, the divine power he received happened to possess a small, but potentially fatal side effect...

Gu Qingcheng has a fiery temper and is a well-known little princess in Jiangcheng, and she has a good boyfriend who spoils her to the sky.

Only her boyfriend’s cousin, Huo Sicheng, opposed her everywhere, and the two were notoriously deadly rivals.

However, at the engagement banquet, when Gu Qingcheng regretted the marriage in public and announced that she was going to marry the disabled Huo Sicheng who was in a wheelchair, the jaws of all the guests dropped in shock.

Just when everyone thought that the couple would fight to the death in private, guessing that either one of them wanted to keep their husband widowed or the other wanted to keep their wife widowed, but the fact is…

“Husband, I’m stuck in traffic and come back a few minutes late. Open the door and let me in.” Gu Qingcheng knocked on the bedroom door with a pitiful expression.

“Sleeping in the living room.” Huo Shao’s indifferent voice came from the room.

“Honey, someone bullied me today.”

The person who bullied Gu Qingcheng disappeared the next day.

“Honey, they all say I’m so fierce.”

Huo Shao glanced at Gu Qingcheng, and opened his thin lips lightly: “They are talking nonsense, you are not fierce at all.”

From then on, Gu Qingcheng set fire to Huo Shao and handed firewood, Gu Qingcheng abused the scum and Huo Shao handed the knife, and the husband and wife worked together without getting tired.

Only Gu Qingcheng knew that before her rebirth, she was provoked and misunderstood by a scumbag to misunderstand Huo Sicheng. After her rebirth, she abused the scum and slapped him in the face, and loved Huo Sicheng with her life.
