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.

Kyle woke up in a land of fantasy and magitech. The usual 'I died and woke up' bullshit, skip all that.

Except he used to be a crime lord, and society here is missing that extra kick.

“Master Ouyang, please smith a divine weapon for me!”

“Master Ouyang, you’re the only person who can forge a weapon with seven attributes. Please make my dream come true!”

“Master Ouyang, could you…”

“Ouyang my *ss! My surname is Ou!”

Ou Yangming was an orphan who was adopted by a reputable old blacksmith from a military camp. After working as a helper under the old man for years, he was given a chance to acquire the Military Fire—a trait allowing him to smith and restore equipment with the Military Fire produced from his hands.

Gifted with mental power, Ou Yangming controlled his Military Fire unusually well and was also strangely talented in martial arts. On top of it, he could also attach Unique Attributes into weapons with a hundred-percent success rate. Those who belittled Ou Yangming because of his background and age eventually honored him so much that they would do anything to get their hands on his equipment.

Little did Ou Yangming know that as he slowly unfolded the mysteries of the Military Fire and his mental power, he was advancing step by step on the immortal path to Heaven!
