All the Heroines are my Ex-girlfriends - Chapter 5 - : Seeing Through the Spring Breeze: "Encounter"

Oliver was a shy boy who always got nervous whenever he interacted with girls, which is why he had no girlfriend throughout high school.However, all that changes when his parents decide to help boost his confidence so that he doesn't have any problems interacting with people of the opposite gender in the future.But how do they do that?

Cha Myung-jun, a sergeant who neared the end of his military service, found himself confined in the Ministry of National Defense’s bas**ent for over three decades due to his newly awakened abilities, just before the outbreak of war. Spending thirty years as the world’s most formidable blacksmith, wielding nothing but hammers, he skillfully outwits the watchful eyes of the Ministry of Defense to serve the war effort and reset the course of time. Now given a second chance at life, can he lead a successful campaign to avert humanity’s downfall and secure its salvation?

Chen Xi looks at the soldier who just threw a rock weighing a few hundred kilograms away and looks at the sky speechlessly. Is this really the late Eastern Han Dynasty?It doesn't make sense to see Lu Bu single-handedly cut through the ten-thousand-strong cavalry.Zhao Zilong ends up truly possessed by a dragon soul. Is he really human?Dian Wei single-handedly defends Cao Cao as they storm out of the enemy camp and slaughters a few thousand cavalry of the enemy. His combat strength is off the charts!Is there something wrong? Chen Xi touches a goose feather fan and fans it. A strong gale blows and he sighs.“This must be some mythical story, right? Even I'm not normal anymore.”

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.
