Ark (Published Novel) - Vol 13 Chapter 5: [TL:

Upon meeting the girl who would become her adopted younger sister, the duke’s daughter Christina regained memories of her previous life. Through those memories, she learned that her new sister, Mishuli, was the heroine of a certain story. And though the story depicted a Christina who abused her sister, the real Christina turned into a siscon who spoiled Mishuli to no end.

On this land of real souls, with millions of different martial art institutions, there’re so many strong fighters just like the trees in the forests.

Wang Yi had just transmigrated when he experienced being cheated on, going through a divorce, and being kicked out of his home. These were events faced by a useless male character.

However, he soon discovered that this world seemed out of sorts. There were martial arts grandmasters and martial arts clans?

Fortunately, he activated the Martial Arts Sign In System.

[You have successfully signed in and obtained the Dragon Elephant Wisdom Technique. Please cultivate according to the instructions.]

Thus, Wang Yi kept signing in until he leveled up and became a martial arts grandmaster. After that, he discovered the truth behind his wife’s affair.

It begins on the mountain.

With the glint of a knife, a flash of steel in the hands of a sworn brother. A betrayal.

Stabbed and pushed down the mountain, Zi Chen lied within the red-stained snow, left to die.

This is where it begins; he is given life by lightning,
baptized by thunder.

Those who had once betrayed him should all suffer in his cruel revenge.
