MTL - Tokyo Video Game Tycoon - Chapter 297 two mountains

In the vast and boundless continent Cangtu, there were ancient sects governing the Ten Old Domains, unworldly immortal clans beyond the Blue Sky, and primordial demon gods dominating the dark abyss that together created a great number of brilliant stories over the long course of the history.

In this very world, there was a boy, named Lin Xun, who embarked on his journey to the pinnacle of strength alone through cultivation and spiritual tattoo inscribing.

Escaping alone from the Mine Prison where he had been living since he was adopted by Master Lu, Lin Xun knew nothing about his identity but the little information his adopter, Master Lu, had told him. With two ancient spiritual tools Master Lu gave to him before the destruction of the Mine Prison, Lin Xun started his journey to Ziyao Empire, where he is supposed to find out the truth of his lost Spiritual Vessel and the person who slaughtered his family, leaving him orphaned.

Will he be able to unlock the mysteries of the two magic treasures, unveil the secrets of his identity and create a legend of his own?

Travel to the primitive world, open up wasteland and farm land, tame animals and fish, build houses…

Jiang Xuan wants to create a tribe of his own!

PS. Cover not mine, I just found it on google.

There was a popular comic that captured the hearts of readers not because of its plot, but rather the bromance between the two protagonists, a crown prince and a duke. Their friendship & mutual trust led fans to ship them endlessly, with countless fanfiction stories ranging from dating to marriage or even incorporating omegaverse settings.One particular m-preg fanfic novel became extremely popular among fans, where the previously cold duke becomes pregnant.But the popularity of both the original comic and this novel caused everything to become unbalanced, until something strange happened - these works of fiction turn into real worlds that collided, creating an error that connected them together.In the world of the comic:Carlton from the fanfic world gazed up at his husband with longing eyes. “Husband...” He pouted, “Why don't you kiss me today?”Alaric from the comic world recoiled slightly and goosebumps broke out over his skin as he moved away. “Please don't come close to me...” He said tersely.Meanwhile, in another world:Alaric from the fanfic world, pulled his beloved Carlton into a warm embrace and peppered kisses on his cheeks. “Darling, are you mad at me?” Alaric asked affectionately. “It's okay, you're still cute.” He leaned down to whisper into his ear before continuing. “But don't forget to comfort all our children, they think you're mad at them.”Suddenly, seven children barged into the room and called out to their fathers. “Father, Daddy!” they exclaimed.Carlton's frozen expression spoke volumes about his state of mind as he tried to process what was happening. His murderous gaze fixed on Alaric as he muttered through gritted teeth. “Whose children do you say they are....?”
