Don’t Concern Yourself With That Book - Chapter 18

Rael, once a teenager crippled by social anxiety, is reincarnated 1,553 years into the future after reading a book about Milford, the legendary God of Machima—a man who commanded armies of Steelborn, Machnoids, and Autonoms across the universe. Gifted with the Machima Bloodline and guided by Dominica, the World Domination System, Rael quickly rises to become the strongest World Conqueror.He first saw them on the book’s cover—steel women with lifelike faces, beasts with razor limbs, and looming above them all, a god in robes with a mechanical hand raised high. Coiled over him were a gigantic centipede and serpent of metal, guardians of his legend. Now, deep in a junkyard centuries later, Rael forges his own path. His first creation: an unbreakable fortress born in the dirt, a hulking Steelborn Tortoise with a mind sharper than any AI—crafted by Rael’s divine talent. From admiring Milford and wishing to be like him, Rael now marches forward to leave his own mark on the universe.Join him as he rises in rank across his world—and beyond.

In novels with a stud there is always a Senior Martial Brother like this:

In the early stages of the novel, his innate talent is high, his cultivation is good, his appearance is handsome, and he has an intelligent, cute younger Martial Sister as a fiancée.

In the middle stages of the novel, he is caught unprepared and defeated by a young disciple (the protagonist) in the sect who’s hardly remarkable at all. From then on, he falls from his godly altar and loses his brilliance. Even his young Martial Sister leaves him for someone else.

In the late stages of the novel, he continues to turn dark, going down the Demonic Path and becoming the major villainous boss. However, the protagonist still ruthlessly defeats him and his soul is eternally sealed.

Once Qin Mo opened his eyes, he discovered that he had become this Senior Martial Brother.

There is always such a person in the world who likes to take their ex/Bai Yueguang/best friend as a stepping stone for their love.
These exes/Bai Yueguang/Girlfriends are called female supporting roles. They obviously did nothing. Just because they were involved with the male and female protagonists, they were trampled on, hurt, and even left a shadow that will never go away for a lifetime.
Jiang centrifugally felt sorry for those innocent girls, so he traveled from one world to another to help them cross that hurdle.
However, after a certain world, the mission is obviously wrong.
Jiang Li: “I will treat you well.”
“It’s not enough.” The girl imprisoned Jiang Li in her arms, breathing warmly: “Don’t leave, you must always be good to me, only to me.”
Jiang Li: ? ? ?

Tian Shen was your average unordinary guy—living a monotonous life. One day, fate (or rather, Truck-kun) decided to grant his wish… by sending him flying into another world at 120 km/h.When he woke up again, he found himself in the body of an outer disciple of the Beast Taming Sect. His talent? Nonexistent. His reputation? Of a molester’s. Just when he thought he was doomed to be cannon fodder, a golden screen appeared before him.『Ding! Congratulations, Host! You have activated the Attribute System.』『Congrats host, you killed 5th stage of body refining realm cultivator and gained Qi points ×30.』『Congrats host, you killed 1th stage of Qi refining realm cultivator and gained Luck points ×80.』『Absorbed white Attribute orb, gained 1-star sword.』『Absorbed golden Attribute orb, gained divine Artifact.』Tian Shen: “…Huh?”Armed with his new system, Tian Shen embarks on a ridiculous journey—casually strolling through battlefields to collect fallen attributes, dodging cultivation technique manuals (which drop on his head), and even trolling young masters into fighting just to farm their stats.But as he levels up in the most absurd way possible, he soon realizes… is he cheating too much? Because now, heavenly tribulations, ancient sects, and hidden experts are all eyeing him.Tian Shen: I am favored by the AUTHOR of this book, you lots can't even handle my shoes.*Rumble**Crackle*Again Tian Shen: I-i was just joking, don't take it seriously.**BOOM**
