[Dark cultivation + survivalist approach + daily intelligence + system + decisive killing + playing dumb to fool the enemy]

Chen Yuan, a lowly office worker from Blue Star, was transported away by a great wind and transmigrated into the body of the lowest-ranking blood slave in the Blackwood Sect, where he was forced to have his life essence drained by demonic creatures every day. When his will to survive reached its peak, he awakened the [Daily Intelligence System], thus beginning his journey to defy fate...

Q: What if I transmigrate and become a hidden boss? Choose one of the following options. B: [You kill a level 7 goblin and gain 50 experience points.] Option? What option? A starting boss + leveling up, what's there to hesitate about? [You annihilate a goblin tribe and gain a large amount of experience points, you level up...] [You kill other bosses and gain new feats...] [Your strength is increasing, congratulations, you have become the king of the wilderness.]........ "The laws of the world from the stars, the noble guidance from the fate of all living beings, please tell me how to end this chaotic world?" "Hmm? Is it enough to just kill this bloodthirsty demon? I will do my best." "However, the majestic laws of the world, the eternal guidance of fate, why is he pointing in the direction of the savior?"

[Multiple female leads] [Dual Devil Fruit abilities] [Scroll King]

He is the man who respects Kaido the most;

He is Kizaru's close friend, a rascal in the eyes of Sengoku, Garp, Zephyr, and Tsuru, and the Five Elders' number one enemy.

He was the childhood nightmare of Luffy and his brothers, the target Zoro vowed to kill, the scumbag pervert Sanji hated most, the pervert in Franky's eyes, and the idol of Usopp and Chopper.

He was the man who transformed the white-bearded man from a "kind father" into a "strict father."

He was the opponent who made Red-Haired Shanks lose face; the man who broke Hawkeye's defenses.

He is the one who tramples on the dreams of Doflamingo, Gecko Moria, and Kozuki Momonosuke.

He is the nemesis of evil in the eyes of the common people, a legend of thunder and dragons, and the most powerful and benevolent thunder god in the history of Skypiea...

Ottosama Lodge is unwilling to acknowledge these labels, but he has never spoken out in defense of them.

Because what they said made so much sense...

Roll up your sleeves, guys! You're all too weak! You can't even beat a gorilla? You want to save the world? Are you out of your mind?

All in! (Forget everything, I have to save everyone!)

A heads-up: There are many one-sided crushes, so there will be descriptions of attraction (or something to that effect), but the female lead won't develop romantic relationships with anyone (I can write if/after-flight scenarios or side stories, but not in the main story). ⚠️The relationship between Yuuta Otoko and Rika Inori has been changed to a close friendship, and the nature of "Rika Inori, the Special Grade Cursed Spirit" has been slightly altered ← I'm refining this as I read, so I can't quite define exactly what's changed. (Since there's no proper ending, then there shouldn't be any "romantic love" as a reason from the start.)

Uh, actually, the author wanted to save everyone and also wanted some sweetness, but didn't want any romantic pairings (eyes darting away).

——————————————

The life forms of ancient legends have sung songs of hope tirelessly for millennia. Those who follow, will they find mercy to stay?

Humans are such wondrous creatures; they create and destroy everything. Evil knows no species, and we shouldn't therefore condemn destruction to an extreme degree. All those who yearn to live better should fulfill their desires with their own hands.

Therefore, let's cherish all our beautiful wishes as much as possible; life should never be wasted.

Chen Sansi traveled back to the chaotic end of a dynasty, thankfully with the hardworking system by his side.

He originally wanted to hunt to earn money and someday go to the Martial Arts Hall to learn some basic fist and foot techniques, aspiring just to be an ordinary rich man.

Yet, fate had other plans.

With officials imposing heavy taxes and the Martial Arts Hall bullying the citizens, he had no choice but to enlist in the army to survive, becoming an archer.

From "archery (entry-level)," he worked tirelessly up to "operating a ten thousand weight bow, where arrows cannot be dodged," taking the heads of enemy generals from a hundred miles away!

From "basic soldier's spear technique," he worked tirelessly up to "National Guardian Dragon Spear, growing more valiant with each battle," standing firm with a spear on horseback, alone turning back the Enemy Army of a million!

Years later, Chen Sansi, having campaigned in the south and battled in the north, was truly invincible under the heavens, commanding two hundred thousand of the Iron Cavalry.

Watching his subordinates forcibly ascend him to the throne and become emperor, he felt quite helpless: 'You... you have really caused me trouble!'
