[Upon hearing this, Ye Yu turned his head and saw a naive-looking fairy standing behind him.]
[She was not tall, with a very cute appearance.]
[Ye Yu felt unfamiliar with her, which only piqued his curiosity further.]
[The fairy couldn't help but furrow her brow.]
[She spoke again: Do I need to give you the passphrase for you to hand it over to me? Okay okay, you win.]
[Here's the passphrase: You ignore me!]
[Ye Yu was completely bewildered.]
[He asked with confusion, I ignore you?]
[The fairy immediately smiled, Alright, the passphrase matches. Can you hand it over now?]
[Ye Yu raised an eyebrow slightly.]
[You ignore me, I ignore you.]
[And this counts as a passphrase? Who came up with this?]
[Ye Yu stared at the fairy for a moment.]
[He asked softly, Do you know who I am?]
[The consecutive questions made the fairy, Lan Lianyan, impatient.]
[She walked up to him immediately.]
[Pointing her finger at Ye Yu, she said, You are my contact, Zhao Likang.]
[You've been undercover in the Mystic Yin Sect for thirteen years.]
[And I am your new handler, Lan Lianyan.]
[Though we're meeting for the first time, since the passphrase matches, what more do you need to believe?]
[Quickly bring out the recommendation letter for me so I can join the Mystic Yin Sect.]
[This way, we'll have a better chance against the demon!]
[Upon hearing this, Ye Yu narrowed his eyes slightly.]
[The names Zhao Likang and Lan Lianyan were both very unfamiliar to him.]
[With hundreds of disciples in the Mystic Yin Sect, Ye Yu couldn't possibly bother with everyone's names.]
[But from Lan Lianyan's words, he gleaned a lot of useful information.]
[For example, Zhao Likang was an undercover agent.]
[And Lan Lianyan was his new superior, whom he had never met before.]
[Hence, this misunderstanding occurred.]
[Now, Lan Lianyan wanted to infiltrate the Mystic Yin Sect to collaborate with Zhao Likang in dealing with the demon.]
[Ye Yu wasn't clear on who this demon was.]
[But there was more than a fifty percent chance that it could be him.]
[Because there was no need to go through so much trouble just to deal with an ordinary elder and sneak two people into the Mystic Yin Sect.]
[Watching Lan Lianyan's stubborn yet adorable appearance, Ye Yu couldn't help but smile.]
[It would be a pity to kill such a naive girl so soon.]
[Let's play with her a bit first.]
[Consider it a way to relieve boredom.]
[So, Ye Yu took out a piece of paper from his storage ring and casually wrote with large characters: Recommendation Letter.]
[He handed it to Lan Lianyan.]
[Upon seeing it, she looked stunned and asked, Are you kidding me? Weren't we supposed to have a recommendation letter from an elder?]
[You just wrote these words casually, and that's it?]
[Ye Yu immediately explained, This is a recommendation letter imitating the handwriting of the Grand Elder of the Mystic Yin Sect. It will definitely get you successfully admitted into the Mystic Yin Sect, so don't worry!]
[Lan Lianyan looked at the recommendation letter in her hand, then back at Ye Yu, feeling that something was off no matter how she looked at it.]
[Just as she was about to speak, Ye Yu cut her off.]
[Don't worry, you are my superior. Why would I deceive you?]
[Go on now, go on!]
[Lan Lianyan scratched her head and pondered for a moment, thinking it seemed to make sense.]
[So she slowly walked away.]
[Taking a step, she turned back three times.]
[After walking about ten meters away, she quickly ran back.]
[You really didn't deceive me, did you?]
[Ye Yu shook his head, but the smile on his face never faded.]
[In the end, with a nervous heart, Lan Lianyan left the mountainside.]
[Not long after she left, a figure cloaked in black quietly arrived at the mountainside, beginning to look around.]
[Are you looking for me?]
[Ye Yu's voice suddenly sounded behind him.]
[Hearing this, the person was startled, quickly pulling down the hood of his cloak.]
[He said, Inner sect disciple Zhao Likang, greets the Sect Master. I'm not looking for you, Master. I'm just searching for something I lost here a few days ago.]
[Upon hearing this familiar name, Ye Yu immediately understood that this was the undercover agent originally meant to meet with Lan Lianyan.]
[He had just intercepted him.]
[Then, Ye Yu smiled and said the password for their meeting.]
[I ignore you.]
[You ignore me? Zhao Likang replied reflexively, but as soon as he finished, he realized something.]
[The next moment, Ye Yu wasted no more words, immediately using his Spirit Devouring Technique to absorb all of Zhao Likang's spiritual energy and convert it into Yin energy to nourish himself.]
[After improving the Spirit Devouring Technique, Ye Yu could not only devour the spiritual energy within others but also probe their memories.]
[After a moment, Ye Yu understood the whole situation.]
[For the past century, the Mystic Yin Sect had drawn too much attention from the righteous sects of the East Sea Continent.]
[Therefore, one of the Sacred Lands, the Flower Spirit Mountain, had sent several undercover agents into the Mystic Yin Sect.]
[Zhao Likang was one of them.]
[Later rumors claimed that Ye Yu was also born on an extreme Yin day.]
[This made the Sacred Lands even more uneasy.]
[Originally, Zhao Likang's superior, Zheng Tianya, was planning to infiltrate the Mystic Yin Sect and cooperate with Zhao Likang to gather information about Ye Yu.]
[They aimed to seize an opportunity to eliminate this demonic leader.]
[Unexpectedly, Zheng Tianya had recently died in a duel, leaving them with no choice but to hastily send Lan Lianyan instead.]
[Though Lan Lianyan seemed naive, she was the only genius cultivator from the Flower Spirit Mountain to reach the mid-Integration Realm in just six hundred years.]
[The main reason for sending Lan Lianyan was also because she had been secluded in cultivation for many years, and no one knew her.]
[A fresh face would make things easier.]
[Today was the first day Lan Lianyan and Zhao Likang were to meet.]
[This place was their agreed meeting spot.]
[Ye Yu accidentally blurted out the password, and that's what made Lan Lianyan mistake him.]
[After learning this information, Ye Yu let out a cold laugh.]
[So, it was really aimed at him.]
[Flower Spirit Mountain, huh?]
[I'll remember this grudge, Ye Yu thought.]
[However, these details made Ye Yu realize that Lan Lianyan couldn't be killed just yet.]
[Perhaps he could extract the names of all the undercover agents from her.]
[With this in mind, Ye Yu's figure flashed, and he arrived in the guidance hall of the Mystic Yin Sect.]
[Sure enough, at this moment, Lan Lianyan was here applying to join the Mystic Yin Sect.]
[As she nervously handed over the paper with the words of recommendation letter on it, Elder Qian Baitong didn't even look at it and threw it aside directly.]
