Up to this point, they had read about 60% of the “Great Empress Heart Sutra”. The remaining 40% mentioned the details on the cultivation after Spiritual Energy was created. As for anything that had to do with Yin-Yang integration regarding the Spiritual Energy, it was inseparable from duo cultivation.
What made Lin Xintong’s ears become even redder was that the duo cultivation written in the “Great Empress Heart Sutra” also paid close attention to postures as well as energy circulation.
The energy circulation was fine, but the duo cultivation postures made Lin Xintong extremely embarrassed.
In fact, several martial arts manuals would include cultivation formulas along with the actions the person learning it should perform. Some manuals would even draw out human figures, indicating what a warrior needed to do.
Although the “Great Empress Heart Sutra” did not do so, the descriptions with the Yin-Yang energy circulation was already explicit enough for Lin Xintong to understand the postures needed for duo cultivation.
Some of the postures themselves were nothing much, but if she did them in front of Yi Yun, then things would be different.
For an otherworldly girl, who was usually proud and indifferent, to do these actions was a challenge of Lin Xintong’s sense of shame.
The more she read, the more Lin Xintong found it difficult to accept. This caused her breathing to become chaotic as she became more and more embarrassed. Finally, she could no longer bear it further and snapped close the ancient book.
The simple cover was very well textured, so no matter how she looked at this classic canon, Lin Xintong found it hard to imagine that it was such a forbidden book from its cover.
She took a deep breath as she tried her best to calm herself.
Her back faced Yi Yun for another 30 seconds before she was finally able to appear without that clamped up and embarrassed expression. Only then, did she slowly turn towards Yi Yun.
It appeared as if she had never seen the explicit contents and nonchalantly told Yi Yun, “The content towards the end of the ‘Great Empress Heart Sutra’ requires a very high standard in cultivation level. I do not think we can cultivate it, so let us not look at it for the time being. There is no point in biting off more than we can chew. Let us slowly cultivate with the beginning content first.”
