This is a bizarre and mysterious world filled with various sinister cultivation methods.

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!

Because she was obsessed with survival games, Tang Su was forewarned in her dream. She hoarded resources like crazy before she transmigrated into a survival romance game, becoming the gold-digger female support character. She would end up tormented by the female lead, and her family, who used to spoil her, were destroyed as well. As for the female lead? Six big shots with different personalities spoiled her as she rose to the top.

However, Tang Su had a shop with billions of resources, so she did not care. Outdoors, she could destroy monsters and build bases; indoors, she could make gourmet food and build squads, leading her family as they traveled across the world where dangers lurked everywhere. She made her three brothers the champions of the world and took in the lonesome final boss, living such a great life that the female lead was jealous. The final boss was handsome, aloof, and ruthless, though he was more than that in private.

While he kept everyone at arm’s length, he was more than affectionate towards Tang Su, restraining his cruelty just to get her. He carefully disguised himself as a minion and willingly revealed his fatal weakness to her, giving her all his tenderness. Unable to resist him, Tang Su obediently submitted to him. After all, everyone’s heart would race when they saw the final boss spoiling his wife! However, what was wrong with those six big shots? Why were they saying that they didn’t mind another comrade? Big shots: Tang Su, we can warm your bed for you…Shen Zhiting: Haha! Dream on!

At the foot of the Misty Cloud Mountain, a young girl in a white dress nestled in Mu Yu’s embrace as she cried, “I, Nalan Yanran, would rather die than marry that young master of the Xiao family. I only wish to marry you in this life.”

“Ding!” You have successfully triggered a 3-star mission! to help Nalan Yanran go to the Xiao family to end the engagement! ”

“Wait a minute, this script isn’t right. Can’t we just not do it?” Mu Yu felt like crying.

“Either way! Either die! ” The System pulled out a 10m long broadsword.

“Stop, can’t I do it…” Mu Yu submitted.
