Dark, cold and calculating, he makes use of all his resources as he sets off on his adventures to meet his goal. Face? Who needs that… Hmmm… that guy seems too powerful for me to take on now… I better keep a low profile for now. You want me to help you? Sure… but what benefit can I get out of it? Nothing? Bye. Hmmm… that guy looks like he might cause me problems in the future. Should I let him off for now and let him grow into someone that can threaten me….. Nahhh. *kill*-

Jumping From World to the world: Intergalactic or Urban, World of Cultivation or Continent of Magic, Fighting other protagonists, hooking with beautiful heroines, plundering treasures, and suppressing a myriad of people, Our Protagonist(Villain) can do it all.

After living an ordinary life for years, a man finally got transmigrated to another world. He woke up in the body of a boy named Jun Tianyun.

“A world which got its own protagonists and villains, am I just a side character?” Jun Tianyun mumbled.

Thankfully, he activated Heaven's Fortune System.

“Jun Tianyun! You crippled my power and stole my wife! You villain! You will be punished by heaven!”

A protagonist screamed as he coughed a mouthful of blood.

“I didn't do anything. It was your fate!” Jun Tianyun explained kindly.

“Brother Jun! Because of you, I am still alive and living a normal life with my wife and two children. You are a saint!”

A villain spoke with an emotional voice.

“I didn't do anything. You earned your chance of redemption.” Jun Tianyun sighed.

[ Ding! A female with high Destiny Point is detected! Whether Host wants to steal her destiny or conquer the heroine?]

“This...” Jun Tianyun fell in dillema.

“Sigh, Changing the fate, So burdensome.”

Jun Tianyun sighed as he saw a bunch of heroines fighting for him.

“Hurry to the hospital and donate your blood.” “Go to the hospital at once.” “Remember to donate blood at the hospital.” Even if she had already been donating blood for three times in the past few months, which then took a toll on her body, Huo Chuan never felt an ounce of pity for his so-called wife. After three years of marriage, Huo Chuan would only ever contact her to ask her to donate her blood to the hospital. No, accurately speaking, she was selling her blood. Selling it to Huo Chuan’s beloved woman, Bai Ting.

Yun Qing had been working hard to play the role of a good wife and secretary, but Huo Chuan’s family thought nothing of her. They were enigmatic and petty toward her. Yun Qing even had to do all the cleaning and cooking alone at home. Her existence was so menial that one would even assume she was a maid. In the company, everyone underestimated her. Yun Qing had had enough so she said, “Let’s divorce.” Perhaps she still had hope, but her husband’s reaction completely disappointed her. “What are you throwing a tantrum for? Name your price. The doctor says that Bai Ting is in a critical condition!” Huo Chuan’s mother said, “A lowly secretary like you should be grateful that you married into our Huo family, so why are you making a fuss?” Huo Chuan stared down at her. “I know that you’ve donated more blood this month, but I’ve transferred you the compensation fee! I can tolerate you asking for more, but I won’t tolerate your tantrum!” Looking at Huo Chuan’s mesmerizing features, Yun Qing laughed at herself. He was indeed charming, but he had never ever shown her a pleasant expression. Enduring the pain in her heart, Yun Qing insisted on going through the divorce with Huo Chuan. “Don’t you regret this, Yun Qing!” “Huo Chuan, the only thing I regret is agreeing to this marriage with you three years ago. This marriage had me all battered and bruised. Enough is enough!” For Huo Chuan, she gave up her status and ignored her family’s advice. She pounced at Huo Chuan like a moth to flames, only to receive his indifference and lack of affection in return.

After Yun Qing left the Huo family, she got into a luxurious car. Old Master Yun’s heart ached for his daughter. “Qingqing, you had a three-year agreement with me, that if he doesn’t love you, you will come home and inherit the company. Now, it’s time to uphold your promise.”
