"I have a rough idea of what happened. It's just that we have to go to Yanwang's Mansion at night, and I have no evidence now, so I can only wait for the murderer to send him to the door. Mu Qingfeng motioned for Bai Chenming to be calm for a while.

"Isn't it really a concubine?" Bai Chenming couldn't help but ask.

"According to my calculations, it shouldn't be Princess Yan, she was taken advantage of. There is a requirement for us to go to the Yan Palace's Mansion again tonight, that is, we can't be disguised, and whether we can get to the place where the princess is is depends on you, eldest brother. Mu Qingfeng put forward his own request.

"As long as you can find your father's killer, you can do anything." Bai Chenming said.

That night, Mu Qingfeng Bai Chenming and Mu Chongshan slipped into the Yanwang Mansion under the cover of night.

"Where can we find the princess?" Mu Qingfeng lowered his voice.

Bai Chenming thought for a while and said, "Today, the concubine has just accepted the affairs of the Northern Yan Army, and I think that I should deal with the affairs in the study now. ”

"Okay, without further ado, let's go."

After a while, the group came to the outside of the study, and like last time, they hid quietly outside the window.

"Brother, can I meet my mother? What the hell are we going to do now, didn't you say that you came to find the murderer? Bai Chenming saw the haggard Princess Yan in the study, and said with some distress.

"Wait," Mu Qingfeng said in surprise.

"When the murderer shows up on his own, believe me, it won't be long." Mu Qingfeng whispered.

Seeing that his brother was confident, Bai Chenming stopped urging, and after a while, a voice came from the door.

"Alright, you guys go down, and the idea is to strengthen the guards around you." This deep voice made Bai Chenming feel like he had been struck by lightning.

This is the voice of Lu Min, the chief of King Yan's personal guard, ————.

"Could it be that he ?!!?" Bai Chenming looked back at Mu Qingfeng.

Mu Qingfeng nodded.

What is Lu Min doing when he comes to the study so late? Why do you want to support the guards? Bai Chenming had countless questions in his heart.

"Commander Lu is here, how is the situation of the barracks inspection today?" Obviously, Princess Yan also found Lu Min who came in.

"Princess Qiqi, everything is normal in the barracks. Please also pay more attention to your body, don't work too hard, now that the prince is gone, and the prince is nowhere to be found, we Beiyan are counting on you. Lu Min seemed to be very concerned about Princess Yan's body.

"If I had a choice, I would rather be poisoned by me, and let them suffer here in my place, what kind of sin have I created, and I have to endure such a predicament." Thinking of what happened to her, Princess Yan couldn't help but whimper a little.

"Don't be sad, princess, we in Beiyan still rely on you to preside over the overall situation, it's not too early, you drink this bowl of health tea, rest early, and we will go to the barracks tomorrow to order something." Lu Min persuaded.

"That's right, then Commander Lu should also rest early, as the deputy commander of the Northern Yan Army, the burden on your body is not light." After that, Princess Yan picked up the teacup on the table and wanted to drink it.

"Big brother, if you don't want your mother to be gone, don't let her drink the things sent by Lu Min. Now we can show up. Mu Qingfeng said to Bai Chenming, who couldn't bear it anymore.

"Mother!! Can't drink!! ”

Bai Chenming shouted, broke through the window, and Mu Qingfeng and Mu Chongshan followed him into the study.

With a "bang", seeing her son appear in front of her, Princess Yan was so excited that she knocked down the teacup.

"Someone!! There are assassins!! The traitor Bai is here!! Lu Min was shocked and shouted loudly, and soon there were noisy voices around, it seemed that the guards of the Yan Wangfu were not so incompetent.

"Silly boy, what are you doing here? Why don't you go quickly? You must know that you are now a sinner from all over Beiyan!! Princess Yan found that Bai Chenming had no intention of leaving, and she couldn't help but feel anxious.

"Let's go? If I can't prove my innocence today, I'd rather die here! Bai Chenming was unmoved, he looked back at Mu Qingfeng, and found that he was not in a hurry at all, so he knew that there would be no accident tonight.

Soon, the Northern Yan Army blocked the water around this study, and it was impossible for them to leave even if they wanted to leave at this time.

"Come on, catch these ill-intentioned assassins and traitors Bai Chenming!!" Lu Min shouted loudly.

"Yes!!" The surrounding armor soldiers were eager to try.

"Wait a minute! No one is to move without my orders. Princess Yan suddenly spoke, seeing that her son was so determined, Princess Yan didn't believe that he was here to die.

"Princess, this is Bai Mingming, who killed the prince, we just said today that we want to give you an explanation, do you want to let him go in front of everyone, then we will lose our military morale." Finding that things were different from what he thought, Lu Min was a little anxious.

"What? Commander Lu, isn't it for the sake of the prince to go to the soup and go to the fire? Mu Qingfeng knew it was time to solve all the puzzles.

"What is this?" Obviously, Princess Yan didn't know Mu Qingfeng.

"Mother, this is the child's sworn brother named Mu Qingfeng, do you remember what happened to me and you? The child is in prison, and he rescued me. As for the people behind him, he should also have the impression that the concubine should also have an impression, he is the original commander of the guard of the Lingwang Mansion, Mu Chongshan. Bai Chenming introduced the situation to Princess Yan, who didn't know why.

"What do you mean you're a fellow thief?" Lu Min was unmoved.

"To tell you the truth, the first time I met you in the prison, it didn't feel right, after you and Brother Bai discussed what happened, you found me hiding in the shadows, and your first reaction was to kill me. I couldn't figure it out, but the normal response shouldn't it be to ask who I am. Mu Qingfeng pointed out his first question.

"Hmph, I don't know what you're talking about, I've never been to the prison." Lu Min did not admit what he had done at all.

"Ao, I almost forgot, the commander of the land at that time was covered with his face, so no one knew that it was you, I think the guards were probably also brought by you, and it is estimated that they wanted the prince to die in the prison, and there was no proof of death. By the way, I didn't say it to you, I told Princess Yan. Mu Qingfeng's words changed.

"Your Royal Highness the Princess, you may not know it yourself, the reason why this Commander Lu went to the Heavenly Prison was not to save people, but to kill people."

"I wonder if this little brother can tell me Commander Lu's intention for doing this?" Princess Yan asked.

"It's very simple, as long as Big Brother Bai is dead, then the crime of killing King Yan will not be washed away in this life." Mu Qingfeng said calmly.

"You fart!! Everyone knows how the prince died, no one has ever approached the prince except Bai Chenming that night, he is not a murderer and who else is a murderer!! I see that you came today to excuse the traitor, and I want to know if you can get out of this gate alive!! Lu Min shouted angrily.

"Commander Lu is indeed a good skill, I don't know where I got the news that Bai Chenming did not die in the battle of the prison, and then came up with another plan, so that he could kill people with a knife, I really admire it, I will talk about this later, let's talk about the murder of the prince first."

"Dare to ask the princess, did the prince die from the 'Colorful Bird Spirit Tail'?" Mu Qingfeng asked.

"Nonsense! No one in Yecheng knows who doesn't know! Lu Min said viciously.

Princess Yan glanced at Lu Min lightly.

"Yes, my husband died under this strange poison, and from the end of the engagement, only my son Ming has seen him, although I don't want to believe it, but all the evidence shows that it was Ming'er's poisoner." Princess Yan replied.

"Actually, everyone is wrong, the last person to see the prince is not Big Brother Bai!" Mu Qingfeng said categorically.

"The last person to really see the prince is not Bai Chen's eldest brother, but Lu Min and Lu Commander!!" Mu Qingfeng pointed at Lu Min fiercely.

"Hahaha, I don't know where the traitor found this incompetent person, everyone knows that when we carried the prince out of the practice room in the morning, the prince was already dead, I don't even have the key, you tell me how I went to see the prince in the middle of the night? Still not leaving a trace? Lu Min was indifferent to Mu Qingfeng's identification.

"Commander Lu, don't worry, I never said that you were a hand in the middle of the night." As soon as Mu Qingfeng said this, Lu Min's face was a little unnatural.

"Please also ask the little brother to solve my doubts, what is going on?" Princess Yan also saw that something was wrong.

"Before that, I want to confess to the princess first, in order to find out the truth, I entrusted an old doctor to probe the body of King Yan, and I hope that the princess Haihan will be offended." Mu Qingfeng clasped his fists with both hands and said to Princess Yan.

"It doesn't matter, as long as I can return my son's innocence, I think my husband won't mind." Princess Yan forgave Mu Qingfeng.

"The man I invited is not ordinary." Finding that Princess Yan didn't mean to blame herself, Mu Qingfeng continued, "He is Xiao Mansheng, the former deputy valley master of Wanchun Valley, and after his investigation, he found that King Yan was not only hit by the 'Colored Bird Spirit Tail', but also hit a very powerful drug. As for whether what I said is true, the princess can find someone to check it later. ”

"What I have always been unable to understand is why killing the Yan King has to use drugs in addition to using the world's first strange poison, isn't this an extra move." Mu Qingfeng paused.

"Until one day, we were resting in the inn and were woken up by the noise of pigs being killed outside, and it was a novice who didn't know how to knock the pigs unconscious before we could do it."

"What does this have to do with the murder of King Yan? Why do you think that the king of Yan and the slaughtered pig mean the same thing? If you are disrespectful to the prince, I will kill you!! After that, Lu Min was about to pull out the long knife.

"Commander Lu, if you don't want to be beaten all over the ground by me, it's best not to be impulsive." Seeing that Lu Min had plans to make a move, Mu Chongshan, who had been silent, spoke.

Obviously, the two have fought each other before, and Lu Min is obviously not an opponent.

"Commander Lu, don't worry, if you want to do it so much, are you afraid that I will say it." Mu Qingfeng looked at Lu Min with a smile.

"What the hell is going on with the brother? You're dying of me, what does the story you just told have to do with my father? Bai Chenming couldn't help but ask.

"Actually, we were all wrong at the beginning, Bai Sushen, the king of Northern Yan, didn't die at night at all!!" Mu Qingfeng was shocked.

As soon as these words came out, Lu Min's face instantly turned very pale.

"Big Brother Bai is indeed the last person the prince saw before his death, but that was when the prince was sober. As we all know, the prince's practice room can't be entered without a key, and the keys are inside and outside, and it is difficult to get two keys at the same time, so the murderer didn't plan to open the door in the middle of the night and do it again, not to mention that his scapegoat hasn't appeared yet. ”

"Brother Bai told me that he went to deliver ginseng soup to the prince that night, if my guess is correct, that ginseng soup was drugged, and I think the only person who could touch the soup bowl in the process was the accompanying Lu Commander, right?" Mu Qingfeng noticed that Lu Min's face was getting more and more ugly.

"It takes a lot of time for the drug to exert its effect, so Big Brother Bai can still see the conscious Yan Wang, but after a long time, Yan Wang will be fascinated by the medicine and fall to the ground." Mu Qingfeng continued.

"Could it be that after the prince was fascinated, someone went to poison the prince again?" Princess Yan asked puzzled.

"Impossible, mother, my son carefully checked it that day, and there was no trace of the father's practice room being invaded by outsiders." Bai Chenming said.

"Big brother!! You're thinking about it!! Is there really no one who has ever been in? Mu Qingfeng asked rhetorically.

"This is really not, when Commander Lu came to look for me that morning, we went to the practice room and found that my father was dead, so I asked my mother to get it...

Before Bai Chenming finished speaking, he was interrupted by Mu Qingfeng: "Big brother! How do you know that King Yan is dead?!! ”

"I saw my father lying motionless on the ground, and Lu Min told me that something had happened to the prince. . . ." Bai Chenming suddenly knew what the problem was, and his two eyes stared at Lu Min, as if he was about to breathe fire.

"Nice!! At that time, the prince did not die at all!! I just fainted from the drug!! Mu Qingfeng said loudly.
