Apocalypse: God-level Zombie Synthesis System - Chapter 1999: I have come to destroy your Zhang family.

Mimizuku, a small girl with chains on her wrists and ankles and the numbers “332” branded onto her forehead, wanders into the Forest of Night seeking to be eaten by a monster. However, when the ruler of the monsters, the mysterious and beautiful “King of Night,” refuses to eat her, she tries to formulate a way to convince him otherwise.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

Once through the pirates, Lu En became the son of Monkey d Dragon, a grandfather named Monkey d Karp, and an unreliable and neurotic younger brother named Luffy.

Fortunately, the ghost back system is activated!

The completion of the ghost back is 10%, and the training effect is increased by 100 times!

…

One day, Lu En, a ghost-backed master, appeared in front of Luffy who was shouting to go to sea, and made Luffy cry on the spot.

Luffy: “The pirates in the sea are all monsters like my brother? I don’t want to go out to sea!”

Garp: “For a long time, the two boys, Long and Luffy, with small arms and calves, I really doubt that they are not my sons and grandsons. Like Lu En, they are the grandsons of the old man!”

Warring States: “The strongest creature in the sea, land and air is Kaido? No, it’s Lu En!”

“Boss. Aren’t you too greedy? You are selling this husky mutt for 500,000?”

A cute girl in a ponytail held a husky puppy, whose eyes looked exceptionally wise, in her arms as she glared at Lin Ye. Her gaze was accusing him of being a dishonest trader.

Lin Ye explained, “Miss, I have to formally inform you: this is not a husky mutt.”

The girl retorted, “Don’t you dare trick me.”

“I’m serious. It has the bloodline of Cerberus. Its potential is limitless.”

The girl was stunned by Lin Ye’s words.

After pondering for a moment, she realized that what he said was absurd. Agitated, she yelled, “Are you sure? I don’t believe it!”

Lin Ye gestured at the husky in her arms as he said, “Little fella, get down and show your future owner what you can do. Go!”

“Woof!”

The girl shrieked in horror as she witnessed the little husky spit out a fireball the size of a fist.

……

Many years later, Lin Ye has crowned the Father of Beast-taming of the Blue Planet. When he was interviewed, he said forlornly, “It all started with a husky mutt.”

At the same time, in a mansion, a gigantic red dog with three heads sneezed. Then, it barked at the television before it.

“Woof!”
