Shota's Isekai NTR Adventure - Chapter 1582: Balance of power

This novel is also known as The Indomitable Master of Elixirs

She is the twenty-fourth century’s strongest immortal cultivator, but transferred into a world of magic where demons roamed rampant; a punching bag tyrannized and ostracized by her clan on one side while the scum of a man that is her fiancé humiliated, trampled her on the other side…

Want to ravage her? She laughs as she will soon teach them how to behave themselves!

Magic is amazing? Her Five Lightning’s Bombardment Talisman will turn you into ashes! Medication is very incredible? With one furnace of medicinal pills, useless can also become genius! A vigorous army of a million is very ferocious? With Scattering Beansprout Soldiers, all of you can slowly play!

Smilingly watching as those who court death act vilely without salvation. Those who submit to me prosper, those who oppose me, perish!

Only… For what reason does this Grandmaster whose face is as beautiful as a flower, when facing her, always “secretly casts passionate glances”?

A certain Grandmaster: “After sleeping for so long, now you don’t acknowledge”?

Time travel to become a false widow, with a little bun beside her.

The parents-in-law were unkind, and the sister-in-law was tricky, so they jointly poisoned her to death.

Dong Yue was reborn. Faced with such a tragic situation, she was too lazy to entangle with these beasts and wanted to take Baozi away.

***

The general knelt down to intercede for the guilty minister: “He was framed.”

Everyone sighed: the general is kind.

Dong Yuezhi: He was the one who framed him.

The general ran to imprison the prince: “The prince will not do anything rebellious.”

Everyone sighed: The general is upright.

Dong Yuezhi: Running around is true, just to let the prince be convicted of the crime.

***

He is the only one who is sincere to her.

“Yueyue, I’m stupid, I can’t say good things, I will protect you for the rest of my life.”

“Stupid mouth?” With a simple and honest face, his mouth turned up and down, making people never turn over, “General, stop pretending!”

He restrained his simple and honest expression, and his eyes were deep and burning: “You are the person I love the most!”

[He has killed countless enemies and achieved countless battles, until he met her, and her every move touched his heart]

[She is versatile, there is nothing she can’t solve, but this man has become a candy that can’t be shaken off]
