A Dragonslayer's Peerless Regression - Chapter 24

Qin Lin was electrocuted by playing a nostalgic “Ranch Story” game, and suddenly gained the ability to enter the game. He also found that he could bring the watermelons grown in the game out of reality.

At first, he calculated that a pound of watermelon would sell for 2 yuan. As long as he sells 10,000 catties of watermelon seeds in the game, he can earn 20,000 yuan a day.

Later, he discovered that by upgrading pastures, he could obtain advanced crops beyond the world, raising livestock to obtain advanced livestock breeds that were far beyond the world, and building factories to obtain various formulas that were far beyond the world, and everything was different.

One day, the majority of humanity had a collective thought.

‘I wish the world would just collapse.’

And then, that wish came true.

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!
