[As a matter of fact, there is.] The book hummed in his mind.
There is?!
[Yes. It's a technique used by ice cultivators that changes the temperament and appearance of its user. It's called the Heart Sealment Technique. It's a mental and ice-type support technique you could implement now if you wish.]
Wooyun got excited when he heard this. Really? How do you use it?
[This technique channels the user's qi into their heart and meridians associated with the emotional flow otherwise known as the soul thread. Forming a frost-like seal over them. This doesn't just suppress outward emotion but numbs the internal chaos, granting a more composed, unreadable expression. It also slows the pulse making your breath steadier and allows the person utilizing the skill to have sharper focus and control in high-pressure situations.]
