I won't lock the chapters, and I'll refund everyone for the rest as well... I'm very sorry for making this an unpleasant read qaq] [The protagonist's master and senior brother in an immortal cultivation story...] [The protagonist's imperial tutor, sycophantic ministers, and treacherous officials in a palace story...] [The protagonist's childhood friend and cannon-fodder nemesis, or unrelated older brother, in a school story...] Everyone who knows Lu Jinchao knows he's heartless: handsome, but ruthless. So he was invited to enter various books and save the high-risk characters in them. First up, challenge difficulty level one: a treacherous minister. After transmigrating into the body of a regent who held power over the court and spent his days bullying and oppressing the young emperor protagonist... Lu Jinchao coldly did everything a great villainous minister was supposed to do. He gave the young emperor none of the tenderness he didn't deserve, and spent every day taking pleasure in tormenting the protagonist. Next, all he had to do was wait for the young emperor, now grown into a powerful ruler, to give him a cup of poisoned wine and kill him. Then he could clock out and complete the mission. Lu Jinchao never expected to trip up in the very first world. He drank the poisoned wine, but failed to clock out. The protagonist didn't want to kill him. He wanted to see the once-arrogant regent, who had trampled him underfoot, yield and beg for mercy in tears. The young emperor caught the man trying to escape. When he bent low over him, he discovered that even the cold-blooded, heartless villainous minister could bite his lip and tremble. Feeling the faint shudders in his arms, he said with cold satisfaction, "Do you regret treating me that way?" Lu Jinchao: "..." Mission failed. Lu Jinchao was reborn, not particularly pleased, and faced the protagonist in his youth once more. This time, he changed tactics and decided to be a little nicer to the young emperor. The young emperor was raised to be an upright and honorable man, and aspired to rule wisely. Even when he fell in love, the principles drilled into him since childhood held him back, and he fought to suppress his wicked desires. This wasn't normal. The young emperor thought this over and over. Until he realized that Lu Jinchao was surrounded by a pack of wolves and tigers. His tutor, the chancellor, the general, and even his younger brother, who ignored his warnings every day and called Lu Jinchao "Royal Brother," shamelessly wanted him too... "Why can all of them have him, but I can't?!" His long-suppressed desire erupted all at once, giving Lu Jinchao's mission another spectacular BE! Lu Jinchao: Go to ****! Being bad doesn't work, and being good doesn't work either! The treacherous minister was beyond saving, so Lu Jinchao decided to try a different difficulty level. But he soon discovered that whether he transmigrated as a cool and aloof master, a noble and principled senior brother, or a proud, cold-hearted villainous older brother... the protagonist always found a new way to make his mission fail! * 1v1 HE * The love interest is the same person in every world [Coming soon:
