For the Daoyin Technique to be useful on someone in the Heavenly Fate Realm or above, Gu Yan needed to cultivate Heavenly Energy first.
That's why he didn't go to cure Gu Lan the first day he came to the Divine Feathers Sect.
——————————
After Redsoul's second lesson, he went to the Cultivation Hall where were all of missions available for the students.
He looked for the mission "Cure the Gu Clan young miss" and went to her place.
To the two guards, he said that he wanted to meet his classmate Gu Bei.
They told him he wasn't here, so he tried someone else, "Can I see Miss Gu Lan in that case?"
One of the guards went to ask her and surprisingly, she accepted.
The guard led him inside of a courtyard and then left.
Gu Lan, once the most talented genius of the young generation.
She was seated on a wheelchair: her "illness" paralyzed her whole lower body.
Looking at her, he became mesmerized.
Even with the traces of illness on her face, she still looked really beautiful.
It was already nearly one year since he planned to court her and he wasn't disappointed by the wait!
He was quite surprised that her cultivation was already at Stage-1 Dao of Dragon.
But then he understood, {Well, that does make sense. If she was Heavenly Fate, Heavenly Star or Heavenly Axis, she would just have to die and then reform a body without the poison}
She smiled at him and said, "Mister Gu Yan, may I know what can I do for you?"
"I'm one of the best physician of the Tiny World and I saw a mission concerning Gu Bei's sister in the Cultivation Hall, so I came to see if I could help. I can already tell that you were poisoned by a mixture of Scarlet Apex Herb and Serpent Fruit"
"Really? But I've been examined by thousands of physicians, how come nobody noticed it?"
"In the Tiny World, very few people know of this poison. I suppose that it's the same in the Draconic Ruins Realm. The one who poisoned you must've also killed the ones knowing of it. As for why the the others didn't detect it, it's because the poison is colorless, tasteless and undetectable. After consuming it, your veins will gradually clog up and halt the progress of your cultivation"
She believed him, and asked, "Is it curable?"
"Yes", he took out paper and pen, started to write and continued, "But you were poisoned for at least three years. First you'll need to consume a decoction of these herbs".
He finished as he gave her the paper.
Looking at it, she said, "We have all of them in our pharmacy, is it possible for you to take me there please?"
"Sure"
While he slowly pushed her wheelchair, she said, "You guys caused a huge storm a few days ago, my brother even took me to see the Saint Soul Board. May I ask why you publicly refused to join Gu Heng?"
He laughed a little as he said, "It's because he is just an arrogant clown. We are using him to scare everyone who would want to bully us in the future. Right now my friends are in the Ghastly Ruins and we already know that he is going to send his lackeys to beat us. But he is just going to get even more humiliated, and the others will then fear to stand in our way"
She was pleasantly surprised that her cousin was being manipulated by new students.
——————————
As they arrived to the pharmacy, he prepared a bowl with the brewed herbs and gave it to her.
Gu Lan drank it and a few moments later she exclaimed, "It's working! I can already feel hint of changes in my veins!"
After she calmed down, he said, "You'll need to drink that decoction twice a day until you're totally cured. Now I need to massage your meridians, is there a place where you can lie on your back?"
Some of the other physicians already asked the same thing, so she trusted him and guided him to her room.
——————————
Before starting, he mentally prepared himself to look serious.
He carefully took her from her wheelchair, then started undressing her.
The others didn't do that, but since the decoction of earlier worked, she continued to trust him and didn't say anything.
Laying her on her back, he said, "It might hurt a little at the beginning, but it'll be better after"
When she nodded, he started using the Daoyin Technique on her.
Even if it was only her lower body which was paralyzed, the poison was everywhere.
So he needed to touch her whole body.
She felt an indescribable pleasure as he massaged her meridians.
Clenching her teeth to not moan, she then looked at him, only to see a serious face concentrated on what he was doing.
He acted as if he thought she was in pain and said come encouraging words to her, making it even harder for her to hold herself back.
Thankfully she was a Stage-1 Dao of Dragon.
Due to the difference in cultivation, she could hold herself back enough to not moan until the end, one hour later.
But her heart was still beating really fast and she was out of breath.
When she finally calmed down, he put her clothes back on her, pretending to not see her wetness.
After he put her back on the wheelchair, he brang her back to the courtyard and said, "Miss Gu Lan, I'll come to perform another massage in three days. You should be completely cured in two weeks"
She gratefully looked at him, "Sir Gu Yan, thank you for curing me"
Then he left for the Ghastly Ruins.
——————————
When his two days inside the ruins were over, he became ranked n°1 with more than 200 000 soul scales, earning him 6 000 Spiritual Stones.
Gu Yan then went to use his remaining time in the Saint Soul Grounds to cultivate and became 6-Fate Heavenly Fate.
