Prime Minister Gu was impeached and shocked.

The emperor angrily removed Prime Minister Gu Cheng from his post and sent the two of them to the prison to await trial. He recited that the two women who had married into the Crown Prince's Palace were already members of the Imperial Family and would not be held responsible for their deaths, thus his foster son Gu Yan was sent back to Sky Flame and the justice courts were awaiting trial.

Kneeling on the ground, Gu Cheng's face was ashen, trembling like a sieve.

The Second Prince's brows tightly knitted, and only Duan Chengxuan's expression didn't change.

"This subject knows he is guilty." At this moment, Gu Cheng heavily kowtowed without the slightest hint of fear in his eyes. Instead, he slowly turned his head to look at Duan Chengxuan, "But even Duke Jing and Fourth Prince are unable to escape this responsibility!"

Duan Chengxuan slightly raised his brows, and even Duan Chengrui, who came to the Imperial Court together with him today, subconsciously looked towards the Fourth Prince, Duan Chengyu.

Duan Chengyu was baffled. After hearing Gu Cheng's words, he saw his father's expression change and stood up. "Prime Minister Gu, what do you mean by this? This prince does not ask about political matters, and has never done anything that goes against the will of the heavens. "

"Your Majesty! Yue Shan City's Foreign Minister Ping Village, Sunset Clouds Town, and the Lee family village located hundreds of miles to the south of the northwest border are places where the fourth prince has his own private business and military forces! " Gu Cheng kowtowed once more.

The crowd was astounded, all of them whispering to each other.

The veins on the Emperor's forehead popped out as his cold gaze descended upon Duan Chengyu, "Did you really do this?"

Duan Chengyu felt that this matter was a disaster and quickly knelt down. "This son has not! Your son hasn't left Sky Flame ever since he returned. There must be someone framing him! "

Narrowing his eyes, the emperor was also not a person who did not understand matters.

Duan Chengyu did not have any influence, so even if he wanted to obtain heavy soldiers in these places, it would be extremely difficult. Not to mention that Yue Shan and the Sunset Water Stronghold were both important military places, so his gaze suddenly landed on Duan Chengxuan.

Duan Cheng Xuan raised his eyebrows as well, as he never imagined that Gu Cheng would use this matter to suppress him.

However, after Gu Cheng had finished speaking, the two ministers at the side actually found evidence and brought up the letter from Mount Yue City's Qi Yanbai. The emperor was infuriated as he said, "Go and call back the Tong Boat that is guarding the Sunset Water Stronghold, then send this Qi Yanbai to the justice courts! "I would like to see just who is the one who is secretly hoarding an army right under my nose!"

His words had already made it clear that the Emperor did not believe that Duan Chengyu was the culprit.

Unfortunately, Duan Chengyu had yet to heave a sigh of relief when the Second Prince had already slowly walked up and cupped his hands: "This son still has one more matter to attend to."

"Speak!" The Emperor was infuriated.

When I returned from the border trial, I learned that my imperial uncle had long since discovered that someone was delivering a letter to Erdan. But now, my imperial uncle isn't going to speak of this matter, nor have I sent anyone to deliver a letter to Erdan. The Second Prince's gaze descended onto Duan Cheng Xuan.

All of the subjects began to whisper to each other. Like this, anyone who had the possibility of becoming the Crown Prince would be dragged into this mess.

As the only prince that hadn't been involved in any sort of trouble, Duan Chengrui had instead drawn the attention of others.

Duan Chengxuan sneered. "This king has already told this matter to brother Huang."

"Yes." The Emperor nodded, as though he had cleared Duan Chengxuan of his crimes. However, he was even more curious now that Qi Yubai was one of Duan Chengxuan's men, and the Fourth Prince, who was on good terms with him, was secretly collecting troops outside Yue Shan City.

Something was amiss.

Duan Chengxuan's heart sank. He hadn't expected Gu Cheng's words to bring out so many things. However, how did Gu Cheng know about this matter? Even if the Emperor could prove that he had no relationship with Er Dan, he would definitely suspect the existence of Yue Shan City.

The Second Prince felt that all of this was within his expectations: "It seems that I have misunderstood Imperial Uncle, but for you to have Xiao Hai recruit troops in all four cities of the Frontier City, to have great military power, and to have even expelled my generals, and to have replaced them with your men, is that true?"

Duan Chengxuan was surprised to the point that he choked. How could the Second Prince be so eloquent?

While he was deep in thought, the assistant minister of the Ministry of Revenue had already walked up to him crying and was crying loudly on the ground. "I beg that Your Majesty uphold justice for this old official!"

"What's the matter with all these people?" The emperor frowned.

"Your Majesty! The old official's residence has been plagued by poison time and time again. I thought that the old official's enemies had come looking for me, but I didn't expect that they would invite a reclusive genius doctor, only then did I realize that I seem to have known this poison before. " Guangzhi said as he sobbed with an old face, "The Godly Doctor said that only Crown Princess Jing can cure this poison!"

At this moment, the emperor couldn't even say anything out of annoyance. This matter was getting more and more chaotic.

Duan Chengxuan's eyes narrowed slightly. "What a great number of people mean is that the poison was administered by this king's wangfei?"

Guang Xun was silent as she pointed the spearhead towards Duan Cheng Xuan.

In an instant, all the ministers started discussing amongst themselves.

Gu Danyan was first Madam Yun's child, and there were many opinions on the matter of her father. In addition, the coffin had been stolen, and they had all emerged from the country after taking their lives, and the King's Manor had been attacked by bandits. All three of their wives had been killed, and now that the poison had been used, many people suspected that it was Gu Liuyan who had poisoned them.

This matter was complicated and had a wide range of implications. These few people dared to reveal this matter in front of the imperial court; they were probably the witnesses. However, it was difficult to determine who was in the wrong and who was in the wrong.

"Father, this son has something to say." Duan Chengrui walked over from the side and said in a low voice, "Everyone stay silent, but now that we have witness to the future, it would be better to first lock everyone within the residence and wait for the witness to arrive before settling this matter one by one."

All of the ministers nodded their heads. Duan Chengrui looked at Gu Cheng, who was kneeling at the side, neither arrogant nor impetuous, and said, "Originally, Prime Minister Gu was going to settle the matter today. Even though Prime Minister Gu received some information, he can't bring the matter to justice.

"Just do as you're told." The emperor's heart was finally at ease.

These matters were complicated and complicated. In the end, it all had to do with his most respected brothers as well as these princes.

After this matter was over, Duan Chengxuan thought that Gu Cheng would say something else, but Gu Cheng simply left without a word.

King Jing, the second prince, and the fourth prince were all forbidden from entering the mansion. Only the third prince had been ordered to investigate this matter.

Returning to the manor, Gu Mingyan was reading an ancient medical book when she heard the news about the ban on entry. She then recounted the matter regarding Duan Cheng Xuan's arrival at the imperial court one by one before raising her eyebrows, "Why is the assistant minister of the Ministry of Revenue poisoned again? "Why didn't you come directly to me for an antidote instead of talking to the Emperor about this matter?"

"I'm afraid I want to use you to trample on me before your background passes." Duan Chengxuan sat by the side of her soft couch.

Gu Daiyan naturally knew that this poison came from below the mountain of Zhang Liang, but when she faced Duan Cheng Xuan, she let out a light laugh and patted his shoulder. "That's reasonable. Guess if this poison is a thief or a thief?"
