Despite the surveillance of several Nascent Soul Stage Elders of Immortal Sword Sect, the serial killer could still do something cruel like this under their noses.

At first, all of the Imperial Family members still fully trusted the protection from the several Nascent Soul Stage Elders and quite sure that the serial killer would never dare make a move here in Imperial Garden.

But right now, all of the Imperial Family members completely lost their trust in the protection from the several Nascent Soul Stage Elders, and they already have their own plans to do.

Both the Emperor of Feng Empire and Elder Yang has a really great headache right now when facing the complaint from all the Imperial Family members.

The family members of the dead concubines such as princes and princesses insisted the Emperor and Elder Yang do the total investigation to find the culprit of serial murder and executed the culprit as soon as possible.

Meanwhile, the Imperial Family members that did not have any connection with the dead concubines wanted to protect their own life and family, so they want the Emperor and Elder Yang to just let them get out from Tang Feng City as soon as possible and escape as far as they could from here.

All of them were debating about what to do next so fiercely in a big hall inside Imperial Garden until the dawn has arrived.

The Emperor and Elder Yang decided to adjourn the meeting and rest for a few hours to let all the people here calmed down a bit.

Actually, Tang Li Xue also has a great headache right now though she did not even attend the meeting with Elder Yang.

'Sigh... How the hell the serial killer even did it under our noses like that? At first, I thought Crown Prince Feng is actually the serial killer. But last night, me and Ye Zhen chatted with him for almost an entire night in his room, so I am pretty sure he could not commit that murders.' Tang Li Xue grimaced as she rubbed her forehead while kept thinking.

'It seems it is impossible for us to find the serial killer on our own. Even that Elder Yang is facing so much difficulty to track her right now. Should I try to contact Instructor Lan with my Communication Talisman now? If I reported all the information we find to her, Instructor Lan could probably think of something that we miss and we can ask for further instruction from her.' Tang Li Xue's perfect copy asked.

Different from Tang Li Xue that left everything behind when she escaped from the detention room with the help of Instructor Mei Lan and the others, her perfect copy still has her own space pouch contained many kinds of talisman inside it.

It was the lesson Tang Li Xue got in Quanhai City when her perfect copy faced the skull masked man without any talisman to assist or heal her.

After that incident, Tang Li Xue gave a space pouch to her perfect copy that contained several mid-tier spirit stones and many kinds of talisman inside it.

It seemed her arrangement finally paid off right now, and her perfect copy could use the Communication Talisman in her space pouch to contact Instructor Mei Lan.

'All right, you can contact Instructor Lan right now. You just need to tell her all of the information we got, but you do not need to tell Instructor Lan about my wrong blind guess to Crown Prince Feng… Since it really is embarrassing for me…' Tang Li Xue told her perfect copy.

Tang Li Xue's perfect copy told Elder Yang that she wants to go to the toilet. Then she was secretly looking for a secluded place before taking out the Communication Talisman and using it to contact Instructor Mei Lan.

Inside her room, Instructor Mei Lan, Bing Yi, and Hei Yinghao were still being watched closely by many Imperial Guards.

Some of them already have some suspicion of Tang Li Xue's ice statue, and one of them even already reported it to the Imperial Guard's captain.

But something more urgent suddenly happened when several concubines were found dead, and the Imperial Guard's captain did not have any more time to pay his attention to Instructor Mei Lan and the others.

Meanwhile, the Imperial Guards there did not dare to make any move without their captain's order.

Actually, the Imperial Guards did not have any more reason to detain Instructor Mei Lan and the others since the serial murder still happened even after Instructor Mei Lan and the others got detained like this.

However, the situation in Imperial Palace became too chaotic right now, so no one remembered to lift the detention order for Instructor Mei Lan and the others.

Instructor Mei Lan who still closed her eyes lazily to rest, suddenly opened her eyes when the Communication Talisman that she stuffed in the clothes on her chest vibrated.

Instructor Mei Lan secretly took the Communication Talisman from her chest while pretending to fix her clothes and put the Communication Talisman in her black hood when she was pretending to pull the hood to cover her face more.

"Instructor Lan… something big had already happened." Tang Li Xue's perfect copy said to Instructor Mei Lan through the Communication talisman.

"Tell me everything you find and what happened clearly, including any clues you manage to find. Be sure to not miss anything." Instructor Mei Lan replied with a soft voice.

Tang Li Xue's perfect copy started to tell every information she managed to find from Elder Yang and her own finding to Instructor Mei Lan, including the massacre of several concubines in Imperial Garden.

Instructor Mei Lan chuckled softly after she heard everything from Tang Li Xue's perfect copy and murmured: "Just like before, she still likes to play with everyone's mind. Her way to stir everyone's feeling according to her will is still as terrifying as ever."

"Play with everyone's mind? Stir everyone's feeling?" Tang Li Xue's perfect copy asked in confusion.

"It was clear from what she was doing to those concubines' dead bodies. She wants to make everyone's there feel restless in fear and panic. She wants them to quarrel with each other. Right now, all the people there must feel like several living fishes in the boiling pot. If they jumped out from the boiling pot, they would die. But if they kept staying in the boiling pot, they would die too." Instructor Mei Lan explained.

"I really do not understand it. Why she did not just kill all of her targets at once and just escape quickly from here?" Tang Li Xue's perfect copy asked again.

Instructor Mei Lan rolled her eyes and replied with a lazy tone: "Because her targets are still heavily guarded by someone powerful."

"I dare to bet right now that Elder Yang does not have so many Nascent Soul Stage Elders with him, at least, three or four… One for guarding the Emperor, one for guarding the Empress, one for guarding himself, and the last one is patrolling around in secret to find the culprit of serial murder." Instructor Mei Lan started to explain again.

"The serial killer's target must be the Emperor and the Empress, but they are being guarded by Nascent Soul Stage Elders, so she clearly could not attack them right now. She did not have any other choice than to stir the situation around like this in order to force all of the Nascent Soul Stage Elders to make their move to find and catch her. While she will use that opportunity to strike the Emperor and the Empress, then killed them in one sweep." Instructor Mei Lan concluded her explanation.

"But I still do not understand it… why does she need to do something so troublesome like this if she really is a Spirit rank beast? She can just swiftly attack head-on to kill the Emperor and Empress, then quickly escape from there, right?" Tang Li Xue's perfect copy asked again in puzzlement.

"Not bad! You really have improved a lot since you already can think that far. I have a few speculations about that, but I only sure about thirty to forty percent about it. Let's forget it for now because we can only blindly guess it for now without any further evidence or clue." Instructor Mei Lan said as she shook her head.

"Let's talk about your guess for now… You already observe so many people out there, right? So, you must have someone you suspect, right? Tell me more clearly about it." This time, it was Instructor Mei Lan's turn to ask Tang Li Xue's perfect copy.

"Aaahhh?! Someone I suspect?! I… I have no…" Tang Li Xue's perfect copy started to stutter.

"Come on, do not lie to me. I know from your reaction that you have someone you suspect." Instructor Mei Lan said while chuckled.

"I… all right. I suspect the Crown Prince Feng before, but yesterday night, I and several core disciples spent our time to chat with him, so he definitely is not the killer of those concubines." Tang Li Xue's perfect copy explained in embarrassment.

"Too naïve! If you are suspecting someone, then you must never let your guard down just because he has a perfect alibi that night. On the contrary, you must do your best to confirm if he is really the culprit or not." Instructor Mei Lan rebuked Tang Li Xue's perfect copy.

"I… I am sorry! But, what should I do to do that?" Tang Li Xue's perfect copy asked.

"Listen, the Emperor would definitely hold a lavish banquet tonight to calm down the people there…" Instructor Mei Lan replied.

"Wait a minute… Instructor Lan, how could you know that the Emperor would hold a lavish banquet tonight?" Tang Li Xue's perfect copy suddenly asked again curiously.

Instructor Mei Lan's lips twitched as she thought: 'Little Xue has certainly become smarter than before, but her habit to ask the stupid question from time to time still remains unchanged.'

"Just think about it… the situation there is almost uncontrollable, and all the people were very restless, so the Emperor would definitely need to do something to calm down the people there. I want you to use the chance in that banquet to seduce that Crown Prince Feng and check if he really is the culprit or not." Instructor Mei Lan told Tang Li Xue's perfect copy about what she needs to do.

"Wha… WHAT?! I must seduce that Crown Prince Feng in that banquet?! Instructor Lan, you must be joking, right?" Tang Li Xue's perfect copy raised her voice in shock and disbelief.

"Why not?! We already know the serial killer is a woman, so she will not be able to sleep with you if Crown Prince Feng is really the culprit." Instructor Mei Lan said again.

"But what if Crown Prince Feng is not the culprit in disguise, but really the real Crown Prince Feng?!" Tang Li Xue's perfect copy asked back.

"Then you just have to knock him out until morning comes and pretend as if you already slept with him. Easy, right? Don't tell me that you cannot even win against a weak pampered prince like him." Instructor Mei Lan replied with a nonchalant tone.
