MTL - All People: Combination Division, Synthesize the Undead Army at the Beginning - Chapter 26 Reverse question! (3/5)

Ercella lived a glorious life everyone envied, but died of an illness at a young age.

Before her death, she regretted not having become a proper mother to her son.

But somehow, she went back three years ago.

Ercella is living her second life.

I promise to be a loving mother this time.

However, is it too late?

“Now that you’re doing this, you’re just making me feel uncomfortable.”

The son only pushes her away and she realises that her relationship with the husband, who she thought was fine before her regression, wasn’t actually…

“I am the rot in your foundation. I will crawl back from hell and bury this world.”Those were Red’s final words as his classmates—the people he once sought validation from—watched him dissolve. They stole his life force to fuel their own ascensions, becoming Paladins, Sages, and Kings. They threw his empty husk into the Abyss, satisfied the 'Terrorist's Son' was finally gone.But death was not the end. While his body lay broken in the abyss, his soul drifted to the sanctuary of a Forgotten God.Awakening the forbidden SSS-Rank Talent [Exponential Divinity - 100x Growth], Red realizes that in this world, power isn't given—it's built. He doesn't need heroes; he needs monsters.From the chitin of hyper-evolved insects to dragons, from eldritch horrors to the nightmares sleeping in the dark, he begins to construct a civilization that defies the natural order. Under his hand, the weak do not just survive—they evolve into calamities.The Heroes are leveling up in their golden towers. The Gods are watching from their thrones.But in the shadows, Red’s Strongest Civilization is already preparing for war.[Betrayed and sacrificed, I awakened an SSS-Rank Talent. While others struggle to build a village, my civilization grows 100x faster.]

The weak cry out with all their might, yet no one cares; The strong whisper softly, yet their words penetrate deeply into the heart. A Talent Tree ablaze with flames, every leaf bearing different spirit runes, Lu Ye, reduced to a mining slave after his sect was destroyed, used this to become a cultivator and stirred the winds of change in the Nine Provinces...

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?
