Sword Saints Should Go Tank - Chapter 494 - : 16 wings of light

Yeon-woo had a twin brother who disappeared five years ago. One day, a pocket watch left by his brother returned to his possession. Inside, he found a hidden diary in which was recorded “By the time you hear this, I guess I will be already dead….”

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

The Blood Warrior of the Ungpae Association, who created a sea of blood wherever he went, made the world of the Forces of Evil possible.

The time has come for the legacy of the Blood Warrior to rise once again.

In her last life, Fu Xi was blinded by love, feeling no regret even as she cut ties with her family to marry a scumbag. Eventually bedridden by illness, she could only watch as her husband hooked up with other women, even bringing them to her bedside just to humiliate her. He killed her family members to gain their riches.

Fu Xi swore that if she could have another life, she would exact her revenge!

After her rebirth, she headed straight to the Gong Family and demanded that their young master—Gong Hao, who was paraplegic and bound to a wheelchair—marry her. Everyone laughed at her stupidity, but Fu Xi knew that Gong Hao was the only one who had earnestly loved her. On top of that, he was a very capable man!

Six months after Fu Xi married him, Gong Hao miraculously rose to his feet, reclaiming his family’s property and revealing multiple bombshells: he was the owner of the largest property company, a minister of national intelligence and an anonymous god of war!

Linking arms with her husband in front of the cameras, Fu Xi smiled.

“Why did you keep such a low profile before this, Mister Gong?” A journalist asked.

Gong Hao leaned in and gave Fu Xi a gentle peck on the cheek. “I was waiting for her to find me and save me…”
