MTL - My Teacher is Sun Wukong - Chapter 550 Erlang God's ID card

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!
