I, the Weakest Traveler, Start by Taming the gods of the Old World. - Chapter 42: The Prime minister says...

The Card Creator is a very ordinary profession. Simply put, the incumbent seals various kinds of abilities, illusions, images and so on in blank cards for convenience of use.

Lu Ming, who initially planned to lead an idle life, had a not-so-boring dream now — He hopes to seal the entire world in the cards.

One still needed to have dreams. What if you could realize them?

This is a bizarre and mysterious world filled with various sinister cultivation methods. Once a person begins to cultivate, they will either undergo mild changes in appearance and temperament, descend into madness, or become a great elixir for evil beings to consume...Duan Yun, having transmigrated into this world, unexpectedly comes across a supreme elixir cultivation manual, the 'True Explanation of the Jade Sword.'To his surprise, he is a one-in-a-million cultivation genius who, unwittingly, transforms the manual into something extraordinary. Guided by the Jade Sword, he is able to pierce through everything.Later, as his mastery over various methods grows, Duan Yun, carrying the philosophy of 'the enlightened benefit the world,' never keeps secrets and spreads martial arts across the land.Who would have thought...“Duan the Demon misled me! He said this technique enhances yin and yang, but now I can only squat to pee, boo hoo...”“It was the Demon who taught me this 'Seven Parts Returning Qi'. Instead of blessing me, it brought disaster—I either get killed or step in dung. The fortune-teller said I've lost seventy percent of my luck.”“Don't trust a word of what Demon Duan says! The fairy of the Myriad Wonders Palace was supposed to ascend the whole palace to the heavens, but in one night, she was possessed and turned into a demoness, all due to that old demon Duan's handiwork!”...Duan Yun finds this incomprehensible. All he did was practice martial arts, spread techniques, and occasionally emulate the laws of nature, so how did he become notorious as a demon?This is slander!The same techniques cause no issues for me, so the problem lies with you all, not me!

After dying on Earth, Liam Porter awakens in Twin Land, a strange world ruled by powerful Spirit Masters.Surrounded by corpses and the wreckage of a destroyed carriage, Liam finds himself wounded—newly arrived in this new world—facing the man responsible for his predecessor’s death.Thrown on an island where he must survive, Liam survives a strange demonic ritual and awakens magical powers.In a world where magic reigns and mystical beings (beasts and monsters) are essential for the growth of the Spirit Masters, Liam will follow a unique path alongside an incubus demon-spirit!To get stronger, he’ll have to conquer women and tame beasts!But not only his captors and the beasts—Spirit Masters’ natural enemies—will stand in his way. He will also have to face the depraved reality in which he finds himself!…“I will become the new Beasts God! Nothing and no one will stop me from achieving my ambition!”Expectations:- Fast pace, particularly at the beginning. A balance between lots of action, kingdom building, slow analysis of the cultivation system and rune creation;- Dark truths of a medieval society;- The MC is a curious earthling with above-average intelligence. He’s not a genius, but he will bring some things from his past life into this world in order to have some advantages (later in the story);- Harem;- Dual cultivation; (it’s the MC’s main cultivation method);- From weak to strong;- Sect building (later in the story).
