Mech: Shattering of the Galaxy - Chapter 15 - The Ring

A mysterious car accident caused her to be bedridden for three years.

After Ning Qing woke up, she learned two things.

One was that her elder twin sister had died in a car accident three years ago.

The other was that she had already married someone.

Her husband was Nian Lie, the eldest son of the Yan family who owned the biggest conglomerate in Yan City.

He treated her as a substitute for her elder sister. While he put her through torture, he would tell her that he loved her with reddened eyes.

Initially, Ning Qing wanted to divorce him, but later on, she indulged in his ambiguous love.

Until she stood outside the wedding venue where he was about to marry another woman.

Her heart was dead. Nothing was worth holding back anymore.

She wanted to escape, but she was unwilling to let him live the rest of his life peacefully.

Hence, under the reporters’ flashing lights, she stepped onto the bridge and jumped off with her nearly due baby…

In fact, Ling Yun was the son of a wealthy businessman. But one day, his mother finds out that her husband is having an affair with his secretary. And after that she decided to divorce her husband, but at that time she did not realize that she was pregnant with Ling Yun.

After learning about her pregnancy, she decided to move to another city. And since then, their lives have been up and down. Because of the economic crush, and also his mother's health was getting worse.

He decided to take the 'Dark' path, which led him to near death. But just as Ling Yun was nearing his end, he heard a little girl's voice asking him.

“Do you want to live?”

Chi Yan had always had a weak constitution, and ghosts had always tried to kill him. He had tried many ways to change his situation, but it was all futile.

Coincidentally, Third Master Ye of Shiming City passed away, and a priest informed Chi Yan that Third Master Ye possessed the “look of demon,” Carrying a bit of this man’s ashes and installing an altar for him at home could help control the evil spirits around Chi Yan.

Left with no choice, Chi Yan took a gamble. Amazingly, it worked. However he didn’t expect that he’d be instead be haunted by the most persistent ghost of them all.

Obsessed with love, undying resentment, possessed by evil.
