In This Life, The Greatest Star In The Universe - Chapter 11:

18 years have passed since I was born as Allen, the eldest son of an earl in this world, while still retaining my memories of the present world. This world is peaceful and a stable society. The only extraordinary thing is that I was reincarnated into a world that is lenient on the existence of concubines. I selected a silver-haired maid as a sex slave and second wife candidate from among 10 candidates after a strict fellatio practical exam. I then lived an erotic life at home and at school as an attendant, but my reincarnated life is so fulfilling that I'm worried it will explode, as my busty childhood friend, a noble girl who was unsuccessful, ran for the third wife candidate, and my stepmother, who was my virgin partner, was sold off.

The dawn era after the end of the half century has gradually rebuilt the order, abandoned civilization, and is full of undivided violence and desire.
The noble and powerful pioneers are in charge of the city, and the evil and mad plagues are in the wilderness.
Pure human beings who cannot mutate are the weakest, dominated by the rulers of the pioneers, and are not as good as animals in the wilderness.
A purely humanized young man with a worldly experience has quietly entered the WTO, holding a three-foot long knife and a long-distance desire to boil in the world of purgatory. From the nameless name to the sorrow of the Supreme Court, the name of the black ride is resounding!

Noah Weaverheart was nothing but a poor boy with zero talent in Magic.Stuck at the Apprentice Magus rank for years, he was bullied and looked down upon by everyone in the academy.His pathetic life met an end at the hands of an arrogant noble, who decided to bury him and go about his day like nothing happened.However, as he drifted in between the space between life and afterlife, a set of notifications appeared before Noah.[Suitable Host Found!][Initializing The Supreme Magus System!][…][ERROR! ERROR! ERROR!]Before he could understand what was going on, he found himself jolted back to life, but the notifications wouldn’t stop flooding his vision.[A bug has been discovered in the system!][Trying to fix bug…][Fixing Bug…][…][ERROR! FIXING FAILED!][ERROR! SYSTEM FALLING APART!][…][ERROR! BUG UNABLE TO BE FIXED!][The system has been corroded by the bug. All parameters broken down. Required EXP for leveling up now fixed, limits on quests completely removed, Penalty on quests disabled.]At first, he thought it was a disaster.Then he realized—this bug wasn’t a curse, but a huge blessing in disguise!With no restrictions holding him back, Noah could now level up endlessly—faster and stronger than anyone alive.From worthless trash to an unstoppable force, he would rise above all… becoming the most powerful magus in existence!But the more he learns about his broken system… he realized the bug might be something far greater, and far more dangerous than he ever imagined.

Yu Qiu once thought that he could rely on his shixiong forever, but when he was captured by the Shadow Demon, he watched helplessly as his shixiong stepped into the bride room together with a woman.

He knew he was one foot in the grave, powerless to reverse the situation.

After reincarnating, how could he walk the path of seal cultivation again?

Rebel? Vengeance? Revenge? Depend on a loyal dog who would be his shield?

That was too low for him!!!

He was going to:

Break up that haze in front of his eyes and turn it into tall mountains.

No longer depend on anyone, but rely on his own strength for everything.

Make every cultivator never say the words “seal cultivation is only supplementary” ever again.

Become the strongest person in the world.

Show that he will become a Daozhang.
