MTL - Nightmare Attack - Chapter 9 Investment, thank you very much

Ethan never expected to wake up inside the game he once played.Tower of Ascension, a world where every adventurer fights their way up through endless floors, each more brutal than the last.Here, skills define everything.But all skills are capped at Level 100. No one can break that limit.Except him.When Ethan transmigrated, his system glitched.His skills could rise infinitely.[Congratulations, your skill level-up][Sword Swing Lv. 999+ — A single slash could shatter a fortress.][Fireball Lv. 999+ — An army reduced to ash in a breath.]What began as a bug soon turned him into the tower’s greatest anomaly.Guilds will hunt him. Kings will fear him.Even the gods guarding the highest floors will see him as a threat to erase.But Ethan doesn’t care.If the world insists he’s an error, then he’ll climb to the very top and prove that even the Tower itself can’t stop him.

Son of a bitch! I just finished this godawful fantasy novel, and now I'm knee-deep in it – as David, the disgraced son of the Solarian Empire's top general! Talk about some twisted cosmic joke. But hold on a damn minute... maybe this isn't all bad. Armed with the knowledge of that trashy plot, I can become the ultimate shadow player, an overlord perhaps. Screw the damsel-in-distress harem too – it's time to pull the strings and become the real power behind the throne. This isekai might be a steaming pile, but I'm rewriting the ending with a little more... Debauchery (wink wink).

[R18 novel with a lot of sexual content]Artem never expected to take on the role of a villain, let alone transmigrate between harem novels. Bound by a system, his task is clear: steal the heroines from all the protagonists’. From Chinese Cultivation and Korean Gate to Japanese Isekai Fantasy, VRMMORPG, and beyond—no heroine is off-limits, and no protagonist is safe!

Seven years ago, Shen Qianshu is impregnated with Ye Ling’s child in an accident.
Seven years later, the little boy becomes famous and is thought of as the nation’s son.

When he suddenly sees Ye Ling appear, he greets, “Hello, Daddy?”
Ye Ling watches as the little prince roars, “Where’s my princess?”
Just as Shen Qianshu is preparing to run with her son, she gets pushed down by Ye Ling.

“You can leave if you want, but leave me a princess first. Let’s have another baby!”
