Dawn of the Void - Chapter 18: Avengers

After choking to death on a watermelon, Rong Jiahui thought that she would enter the netherworld and be reincarnated.

But when she opened her eyes, she discovered, to her very horror, that she had returned twelve years into the past…

Looking at the beautiful and awkward “little brother” that would be conferred the title of Marshal in the future for outstanding military service, she almost let out a snort of laughter.

She firmly decided to hug the thigh of this little brother, and climb to the top of her life!

The plan was beautiful, but it had just one problem.

Why had this little brother… suddenly turned into…

A little sister…

In the past, there was a small cannon fodder who wholeheartedly dedicated herself to the medicinal path.

Only after dying once did she learned that even if she was brilliant, she could only be an insignificant side character used to emphasize the female lead’s limelight. Any relationship with the male lead and other supporting male characters would bring her bad luck.

When going out to collect some medicinal herbs in Qingfeng Valley, she kindly rescued a male side character. The man woke up and saw the female lead and became eternally grateful to her instead. He thought that the monster that hurt him was brought by the small cannon fodder so she was punished.

The cycle repeated and eventually everyone she saved blindly loved the righteous female lead. Ultimately she was killed by one of the men who was entangled with the female lead.

……

So after her rebirth, she began to firmly adhere to the principle of ‘pay me first, then I’ll cure you’.

Male cannon fodders who love the female lead, charge them triple fee!

Male side characters who ambiguously entangled with the female lead, charge them 10 times!

Male lead, the most important one, charged him 100 times!

She single heartedly insisted on using money to distance herself from those men and drew a clear boundary between them. But her ability was too high, that the male lead and side characters from all over the world always came to her for help…

She finally became the richest person in cultivation world!

A black pearl brought Jiang Feng from a doomsday stage where top masters with one emperor, two emperors, three emperors, four deities, and seven peerless cities show off their glory to parallel time and space, and this time and space-the end of the world has not yet opened! !! Under the sky, the youth look up, if I have strength, can I get through … these two time and space! !!
