The Yulan Technique was an Alchemy Technique created solely by the Youlan Emperor. It could fully mobilize the Yulan Sacred Fire for Alchemy and was a truly supreme Ultimate Skill. When the two were used in tandem, they completely overwhelmed Medicine King Valley's Creation Technique!
Compared to the Creation Technique, however, the Yulan Technique had a fatal flaw: it was impossible to pass on. Only someone who possessed the Yulan Sacred Fire could learn this Ultimate Skill and its corresponding Alchemy Technique.
Without the Yulan Sacred Fire, the technique was completely ineffective and could not be performed. This was its greatest drawback.
But none of this mattered to Lin Xuan. 'What does it matter to me if others can't learn it?' All he needed to do was prove that Medicine King Valley's Alchemy Technique wasn't the best in the world. That was enough!
