This is really not mechanical ascension - Chapter 9 - : Overwhelm

Wang Zhong arrived in another world and got caught up in this world’s world war. His cheat ability was an overhead view similar to a real-time strategy game, which allowed him to see the field of vision of his troops! He immediately began micromanaging:“Move the machine gun position five centimeters to the left! Place the anti-tank gun in the woods on the right!”Three years passed like this.Wang Zhong looked at the marshal’s baton in his hand, then at the double-headed eagle flag behind the emperor’s envoy.“There’s an old saying where I come from, ‘Kings and princes, can they be born?’ Do you know this, Envoy?”

I am the sword.
Killing a man amidst a thousand miles, no one dares take ten steps.
Killing a man amidst a thousand miles, no one can take ten steps.
Killing a man amidst a thousand miles, ten steps? Not possible!
I am the sword, the sword is me,
On the path towards heaven, each shall wield their own.

Xue Xi is forced to fall in love at first sight with this dangerous man on their first meeting. With death being the only other option, she makes the first move:

Twenty years ago, the Gu family’s eldest daughter, Gu Wan, went missing without any news on her whereabouts.

The Gu family was left with only the youngest daughter, Gu Chu, so they doted on her.

Twenty years later, Gu Wan returned. Gu Chu was thrilled and she showed her sister around the city, even giving her everything she treasured.

However, Gu Chu gradually realized that Gu Wan was here to take everything away from her, including her fiance! Their mother said, “We owe Gu Wan all of this. We all do, especially you! Gu Wan only went missing back then because you insisted on having a candy.

That’s why Gu Wan went out and ended up going missing!

She had suffered for twenty years out there! You will never be able to fully repay Gu Wan what you owed her!

Hence, the engagement with the Feng family should be given to Gu Wan!”

Their mother even said, “When we arranged this marriage with the Feng family, although we didn’t specify if it was for Gu Wan or Gu Chu, the elder child should take precedence.

Gu Wan should’ve been the first choice. And now that she’s back, she should take what was rightfully hers. What’s wrong with that?” Gu Chu wanted to defend herself.

She didn’t understand why Gu Wan would lie because she didn’t go missing because of her. Yet, the man chose to marry her sister, and that was when Gu Chu regained her senses.

It was just a man. Men weren’t reliable, so she didn’t want him anymore! Their mother even used their family’s shares to bribe Young Master Feng.

However, Gu Chu was surprised when the quiet and unsmiling Young Master Feng suddenly had a change of personality.

Three times a day, he would propose to her. Gu Chu asked, “Are you in such a hurry to have a wife?” Young Master Feng answered, “I’ve been planning this for a long time. Please bear with me.”

Later on, Gu Chu found out his secret. So he had actually been planning for a long time after all…
