In Different World with Naruto System (WN) - Chapter 12 Protection

Changqing has always felt that she’s incomparable to Guan Ying in every aspect. Even though she is pretty and has a good family background, this world is nothing more than a world where Princes are more attracted to Cinderellas.

Her first love that she dearly remembers in her heart for years eventually becomes Guan Ying’s current boyfriend and her fiancé is Guan Ying’s ex. He has yet to forget Guan Ying.

A business marriage brings Changqing and Song Chuyi together despite the absence of love.
In public, he is her friend’s ex and in private he is her husband who cannot be publicly–known.
At the hospital, her good friend enjoys her husband’s embrace while she can only act as though he’s a stranger.
At a gala dinner, her good friend hooks her arm around her first love’s arm shyly and she can only smile and give them her blessings.

…

In this marriage, Changqing thinks that all is well other than the fact that Song Chuyi doesn’t love her.
First, her husband is a doctor and he can treat all her illnesses while saving up on medical expenses.
Second, doctors love cleanliness and her husband would always ensure the cleanliness of the house.
Third, at the end of every month, her thin wallet would grow thick with cash that her husband stuffs in secretly.
Fourth, as a person who doesn’t like to exercise, she always get dragged around by her husband day and night to do some pleasurable exercise that is beneficial for the body and mind.
Fifth, she would never have to worry that she would be out of money.
There are always so many uncountable advantages that Changqing enjoys.

…

After the marriage, on a certain night, Changqing looks at Dr. Song gloomily. “Hubby, why are you so nice to me when you don’t even love me?”
Dr. Song continues reading his medical books and ignores her. It’s sometimes quite a headache when your wife is too stupid and daft.
Until one day, Changqing realises that there’s really no free lunch in this world…

- Description from Novelupdates

In a world fraught with innumerable dangers where living day by day is a struggle, a young man from the modern age transmigrated into such a world, accompanied by a peculiar system made for assassination.

It has been 10000 years. The tide of spiritual energy has returned.

The prosperous Tokyo has returned to the Edo Period and had hordes of supernatural creatures roaming the streets.

In the desert, the Pharaoh was leading his army and awakening from his eternal slumber.

Vampires and werewolves were locked in a constant battle in the Eastern European plains.

Witches and evil spirits were traversing through the markets of Europa.

The feathered serpent was stretching its body on the American Continent, opening its eyes during the cycle of death.

Humans had fallen from the top of the food chain as they remembered the fear that the legends carried.

In this world where demons and monsters roamed, Lester looked at the shadow of the ferocious worm cast on his body and told his system.

“Please give me a set of Sunfire Cape, Randuin's Omen, Frozen Heart, Spirit Visage, Warmog's Armor, Thornmail, oh yes, and the Gargoyle's Stoneplate, Force of Nature, Adaptive Helm, as well as Righteous Glory...”

He then brought his hands together against the trembling monsters.

“I am not talented, but I am going to bust your heads open today!”

“Grasp of the Undying!” Life Value +5

“Dark Harvest!”Damage Growth +5

“Overgrowth!” Life Value +2%

“Gathering Storm!” Spell Strength +100

What? You want me to eat these mutated creatures? Let me tell you! I, Lester, will rather die of starvation or jump down from here than to...

System: “Life Value +40”

“Wow, it tastes great!”
