Building Infrastructure in Ancient Times with My Archenemy

[Blurb One]

Qing Li, a prodigy in magic cultivation from the Wuji Sword Sect, has a sworn enemy: her fellow sect member, the sword-cultivation prodigy Qing Xun.

On the same day, they both failed their Nascent Soul tribulations and transmigrated to the apocalypse. After dying together with the Zombie Emperor, they both ended up in ancient times.

When they woke up, they each leaped three yards away from the other.

Qing Li: "Stay away from me."

Qing Xun: "Keep your hands off me."

[Blurb Two]

The sky was blue.

Qing Li eyed the metal bowl on Qing Xun's stove with envy. Qing Xun couldn't help swallowing as he watched Qing Li sprinkle salt on the roast meat.

The breeze was gentle.

Qing Li looked enviously at Qing Xun's pretty dagger as he cut off a piece of meat. Qing Xun, parched with thirst, gazed longingly at the water in Qing Li's bamboo tube.

The moonlight was beautiful.

Qing Li looked ready to die, and Qing Xun wore the expression of a hero going to his doom. They spoke in unison.

"Let's team up."

Warnings:

1. The male and female leads were both in a cultivation world first. After failing their tribulations, they went to the apocalypse, and only then ended up in ancient times, so they both have golden fingers.

2. One-on-one romance with devoted leads. Both the male and female leads are a little goofy, not aloof paragons.

Theme: Face life with optimism.
