That night, Liu Bang stayed in Liyang Palace to take care of the Emperor Taishang and did not dare to leave half a step, but he also thought about what Zhou Chang said to him yesterday, pacing back and forth in the palace and frowning and sighing. He was thinking: Does Chen Feng have a rebellious heart? When he started the army at the beginning of the year, Chen Feng has been following him to fight the world, and he has made great contributions. After the pacification of the Zhao Dynasty, Liu Bang thought of him as a confidant and asked Chen Feng to supervise the border guards of the Zhao Dynasty, and now Zhou Chang's words also make sense, thinking that Yan Wang Zang Di Han Wang Xin rebelled against the Han Central Committee one by one, and Liu Bang did have some scruples about Chen Feng, who was in charge of the army, and the generals would inevitably have different intentions when they were outside all the year round. Liu Bang thought that Chen Feng had many guests, and there would definitely be the 'remnants' and 'remnants thoughts' of the Warring States Period, that is, the strategy of the Warring States Zongheng family, if he really persuaded Chen Feng to take the throne and divide the north, the Han Dynasty would be in danger. First, in order to verify Chen Feng's innocence, and secondly, in order to cut off Liu Bang's own doubts, Liu Bang just decided to secretly investigate the illegal affairs of Chen Feng and his guests.

The next day, before dawn, Liu Bang repeatedly instructed the palace people to pay attention to the emperor's condition, and sent someone to report to the Xuanshu Hall as soon as there was a situation. Liu Bang also sent his confidants to the imperial historian Zhao Yao and the Marquis of Biyang to judge him, and he hurriedly summoned the Xuanshu Palace. Thinking that Zhao Yao was originally the imperial history of Fuxi, because he instigated Liu Bang to demote Zhou Chang, the imperial historian, to the prime minister of Zhao, Zhao Yao served by Liu Bang's side from time to time, and had a good grasp of words and expressions. Zhou Chang has been gone for many days, one day, Liu Bang finished the review in the palace but saw Zhou Chang's imperial history seal lying quietly in the upper right corner of the case, Liu Bang smiled with a sigh, took the seal in his hand and whispered, "Hee-hee!" I wonder who will have this seal in the future? It just so happened that Zhao Yao was sorting out the approved folds on the side, and Liu Bang saw that he was cautious and smart, and could give him more ideas, so he smiled and said to Zhao Yao, "It seems that no one is more suitable than the prince." Liu Bang handed over the seal to Zhao Yao and let him be promoted to the imperial doctor, and Zhao Yao thanked Liu Bang with joy in his heart.

When the two of them came to the Xuanshu Palace, Liu Bang roughly told the two of them about Chen Feng and his guests, and after the two were stunned for a long time, Liu Bang told them his thoughts, that is, to go to Zhao Dai's second place to secretly investigate Chen Feng and his guests. The two of them immediately received the order with full spirit, Zhao Yao had just taken office, so he wanted to make a little merit; Judging it is a fellow villager of Liu Bang, because of the Empress Lu was named the Marquis of Yang, the trial of his lack of military merits and ashamed, some of the name is not worthy of the name and the corpse is a vegetarian meal, Liu Bang will visit Chen Feng this time to him, and the trial of the food immediately came to the spirit and wanted to do something for Liu Bang.

Even if Zhao Yao and the judge went north, there were two imperial envoys with him, and then Liu Bang also asked Zhou Chang to go north to Zhao to observe the movement and protect Liu Ruyi, the king of Zhao.

Zhao Yao and Zhen Shiqi took the two imperial envoys and went straight to the place to investigate. In January, Daidi official houses, inns, inns, wine shops, private houses, local princes and dignitaries, and wealthy merchants and wealthy families were all secretly visited by Zhao Yao, Zhenshiqi and others. Zhao Yao and the trial were on the way back to the south, and the two were speechless all the way, but they were shocked by the secret investigation of Chen Feng from the bottom of their hearts. It turns out that many of the guests have violated the law and prohibitions, most of which involve Chen Feng himself, such as the guests often keep accounts in the book after eating in the wine shop and inn without paying a penny, such as deducting the taxes of the local people as a military use, such as the guests relying on Chen Feng and bullying the weak and marrying the people's daughters to take advantage of the robbery, and even suggesting that Chen Feng sell the official mantle and cause a large increase in the number of guests, the guests under the instruction of Chen Feng will transport the iron and silk clay pots and other items of the Han Dynasty to the Xiongnu for trading, and the money and goods obtained are distributed by Chen Feng to the guests and their families. The most important one is that someone saw that Wang Huang and Man Qiuchen, the subordinates of the former Han Wangxin, had gone to Chen Xuan's residence one after another, and it took several hours to hide their faces.

Back in Chang'an, Zhao Yao and Zhen Shiqi immediately told Liu Bang the results of the secret investigation word for word, and Liu Bang waved away Zhao and Shen after a long time of silence with a calm face. Liu Bang has a Piri Chunqiu attitude towards Chen Xuan.

Besides, when Chen Feng secretly visited him in Zhao Yao and Zhen Shi Qi Yu on behalf of him, he was returning from the inspection of Yunzhong County, and as soon as he returned to the mansion, a mysterious guest came to the door in a panic to ask to see Chen Xuan, Chen Feng hurriedly went out to greet him as usual, and smiled and waved to the guests, but the guests were not happy at all, but went straight to Chen Feng with a panicked face, and when he came over, he grabbed Chen Feng's wrist and walked quickly to the house and kicked the door. Chen Yan looked at the strange behavior of the inexplicable guest, and asked with a smile what was going on. As soon as the guests stomped their feet, they told Chen Xuan about the arrival of a few strangers, and secretly visited him and his guests in wine shops, inns, private houses, and even places where high-ranking officials, princes, and wealthy merchants and celebrities lived. Chen Xuan's eyes were immediately stunned, and he hurriedly asked who the stranger was. The guests said that a few people were cautious and did not know their names, but they could hear that they all spoke cold Chang'an dialect, and the topic of each inquiry was not far from Chen Feng and the guests under him, but he was afraid of asking some bad things.

Chen Xuan's heart was shocked, his eyes showed panic, and there was already a cold sweat on his forehead, and he paced uneasily in place. "Gong Chen, someone is secretly checking on you, what do you need us to do?" Seeing that Chen Feng looked flustered and had no idea, the guests stepped forward and asked about the steps to do things. Chen Feng raised his right hand, his eyes were very determined, "This is the emperor checking me, don't be impatient." The guest's eyes lit up in astonishment, and he immediately stepped forward and asked, "Why is the emperor doing this?" Chen Yu squinted his eyes slightly, guessed in his heart but said firmly, "Why don't you care about this, the emperor has always been suspicious, and I have been in charge of the Zhao Dynasty's military power for many years, and there must be people who have slandered the emperor many times that I have different intentions." Chen Xuan sat on the mat unconsciously, looked out of the house with deep eyes, and muttered, "Huaiyin...... That's right. ”

The guests planned in their abdomen, and as soon as their eyes lit up, they sat down opposite Chen Feng in one step, approached Chen Feng and said cautiously in a low voice, "In this case, it is better for Chen Gong to prepare early, why not make friends with Wang Huang and Manqiuchen." Chen Feng raised his head and glared at the guests, his eyes hesitated without saying anything, and his hands were on the case and clenched tightly. Seeing Chen Xuan's hesitation, the guests knew what was going on and persuaded him, "Does Chen Gong know the reason for the rebellion between Yan Wang Zang Di and Han Wang Xin?" All because of the suspicion of the old emperor of Guanzhong, he forced the princes to rebel. Now the old trick is repeated, secretly check you, the meaning has been clear, the old emperor will never let go of any anthill embankment in order to protect the safety of the community, Chen Gong has many guests, it is inevitable that some illegal things have entered the ears of the old emperor, he will worry that Chen Gong is too powerful outside and leads the army to fight. According to the servant, if Chen Gong had not prepared to go to Wang Huang Manqiu to communicate the news with him, fortunately, the two of them had persuaded Chen Gong to surrender to the Xiongnu before, and they would have happily accepted Chen Gong, so as to prevent the old emperor's army from going north. ”

The guests' solemn persuasion failed to dispel Chen Xuan's worries, Chen Xuan was silent for a long time after hearing this, clasping his hands together against his chin and squinting his eyes to think carefully, and the guests looked at Chen Xuan with a solemn face. "The emperor treats me very well, since he started his army, I have followed him left and right, and he also trusts me very much, and named me Yang Xiahou. Now just for him to secretly check me, will I betray him and collude with the traitor Han Wangxin's family? If it happens, I will be dead. Chen Feng still reluctantly found a reason to persuade himself and the guests because he didn't want to betray the emperor, and he also wanted to see if he could refute the guests, if he could refute it, it would mean that he was right, and if he couldn't, it would mean that he was indeed wrong?

"Chen's tolerance." The guests shook their heads and waved their hands, and solemnly persuaded again, "Which one has more merit between Duke Chen and the Marquis of Huaiyin?" Chen Feng said bluntly, "Huaiyin is a peerless warrior, why does Helian Gong need to ask again?" The guest Helian smiled and asked, "Who is the Duke of Chen and the Marquis of Huaiyin?" Chen Feng was inexplicable and smiled, "Huaiyin is like a virtuous." Guest Helian also nodded deeply, "But now the Marquis of Huaiyin is under the emperor's surveillance, and the name of the Marquis is actually under house arrest." Huaiyin's merits are high, and the emperor does not want to kill him, but he has won the expectations of the public because of his excessive credit. But looking at what crime Huaiyin committed, he was once deposed by the king to a marquis, and he was tied up in Chang'an for imprisonment without a clear reason? Chen Xuan's eyes flickered and he didn't say a word. The guest Helian said, "The Huaiyin Marquis factor's false rebellion incident, and he was tied up without fault, and now Chen Gong has been in charge of the Zhao Dynasty for a long time, and the guests under the door rely on you and unscrupulously do some things that are disorderly and criminal, you are afraid that you are also a little at fault, right?" Even if the emperor is close to you, how can he get close to the marquis of Huaiyin? The old emperor secretly checked you, which shows that he is suspicious of you, and he is afraid that his Chen Gong's life will not be his own. ”

Chen Feng lowered his head and gritted his teeth, falling into confusion and deep thought. Guest Helian continued to advise, "There will be no turmoil on the flat ground, and there will be monstrous waves." The old emperor will not stop there, and will gradually withdraw Chen Gong's military power in the future, transfer Chen Gong back to Beijing and be imprisoned strictly, Chen Gongzhen and the Marquis of Huaiyin will be accompanied. Chen Gong should make a plan early, first go to Wang Huang Manqiu Chen to communicate the news, if there is no movement in Chang'an, Chen Gong is harmless to himself, if Chang'an changes, Chen Gong also has a reserve army to retreat, is it feasible? ”

Chen Feng hesitated and then 'swooped' and looked at the guest Helian, Helian saw that Chen Xuan's eyes were as firm as steel, and he knew that he was shaken, Helian smiled and arched his hand to Chen Xuan, "Chen Gong will arrange it." Chen Xuan's eyes flashed and fell firmly on the guest Helian, and he bowed his body to Helian solemnly, "If Helian Gong's words are enlightened, he will listen to Helian Gong's words and contact Wang and Man recently." ”

A day later, Chen Feng really sent someone to Wang and Man to communicate the news, Wang and Man heard that Chen Feng took the initiative to ask for a union, they were very surprised, and they went to Chen Feng to discuss the matter in person, Chen Feng did not agree once, so they did not go to Chen Feng in the future. Unexpectedly, today he took the initiative to come to the door to talk about the union, although Wang and Man had doubts, after asking the reason in detail, they agreed without hesitation, and said that General Chen could rest assured that they were General Chen's reserve force.
