When Liu Bang heard Luan Bu's words, he also felt that it made sense, thinking that King Liang was dead, and there was no need to send his ministers to death, so he let Luan Bu go and did not kill him.

Originally, Liu Bang wanted to worship Luan Bu as an official, but he was resigned by Luan Bu, and this kid did not have an ansheng, and after leaving the Han camp, he went to Huainan and took refuge in Yingbu.

The Han army did not mention everything, and said that Chen Xuan, the land of the Zhao Dynasty, rebelled, and Liu Bang led the Han army to arrive for a long time, and Lu Juan handled the matter for the time being.

The army led by Chen Feng heard that Emperor Gao's soldiers were coming, and they were all frightened, so Chen Feng had no choice but to lead the army to the Xiongnu, wanting to make peace with Shan Yu and eliminate Lu Xuan's army.

At this time, Lu Juan also got the news, saying that Chen Fan went to the Xiongnu and wanted to ask for reinforcements, Lu Juan thought to himself, when the Han Emperor led an army of 300,000, he failed to bargain from the Huns, which shows that the Hun soldiers still have a certain strength, if Chen Fan really asked for reinforcements, the following battle will not be able to fight at all.

In addition, Gaozu's rescuers did not come, so Lu Juan felt even more confused in his heart, so he convened the ministers to discuss the matter, among which there was a famous courtier Zhang Sheng, after listening to Lu Juan's worries, he was very happy to offer a plan.

The general meaning is that if Chen Feng can make peace with the Xiongnu, there are only two reasons at most, the first is to make peace with Chen Xuan, he can defeat the Han army, and the second is that Chen Xuan's strength is strong enough to make the Xiongnu tempted.

Although there is a messenger to the Xiongnu today, but the Xiongnu Shan Yu does not know its true strength, will definitely send someone to investigate on behalf of the land, the king can take this opportunity to go to the Xiongnu, and the Xiongnu king to tell, tell them that Chen Feng is just a trapped beast in a cage, if the Xiongnu send troops, it will only cause trouble, and since the siege of His Majesty Bai Mountain, the two sides have nothing to do with it, so as to lobby the Xiongnu, it will definitely make Chen Feng left and right, and when His Majesty comes, the king has already destroyed Chen Xuan, just waiting to invite credit.

When Lu Juan heard this, he was overjoyed and felt that this was very reasonable, so he ordered Zhang Sheng to be the envoy of King Yan and go to Xianbei City to disturb the peace between the two places.

After Zhang Sheng got the order, he hurried towards the Huns, after all, it was a good opportunity to make meritorious contributions, but he met another person on the way, and Zhang Sheng suddenly realized.

This person is none other than the son of the former Yan King Zang Di, named Zang Yan, when Liu Bang conquered Yan Land, he thought that although Zang Di did not make much effort in destroying Chu.

But people didn't help Xiang Yu, isn't this a kind of merit, and under the governance of Zang Tu, the people of Yan Di are rich, it can be seen that Zang Tu is still somewhat useful, but it is precisely because Zang Tu is so popular with the people, so even if you don't rebel, there is no need to continue to exist.

So Liu Bang found an improper reason to expose the rebellion of Zang Tu, and then Liu Bang took it by surprise and led his troops to attack Yandi, resulting in Zang Tu's death.

Liu Bang was a little sleek in his old age, but after all, he was not as ruthless as Lu Pheasant, and he still had compassion in his heart, so he didn't kill them all and let Zang Di's son escape, and Liu Bang didn't order a pursuit.

After Zang Yan escaped, he did not stay in the Central Plains, but fled to the Xiongnu, Liu Bang let him die, but Liu Bang was also his father's enemy, so Zang Yan's mission was to avenge his father and mess up the Han Dynasty.

Although Zang Yan is a fugitive, he is a descendant of Tibet after all, so he is quite popular in Yandi, and there are no less than 100 soldiers who follow him to escape, so he heard about Zhang Sheng's envoy to the Xiongnu.

In his opinion, this is a good opportunity to make a name for himself, so he pretended to meet Zhang Sheng by chance in the Huns, in Xianbei City, in the hotel, Zhang Sheng heard that someone was visiting, and he was also at a loss in his heart.

He ordered someone to invite him in, and after the two finished the ceremony, Zhang Sheng learned that the person in front of him was Zang Yan, and he was shocked, and wanted to ask someone to arrest Zang Yan and hand him over to Emperor Gao for disposal.

Zang Yan immediately got up and waved his hand, "Don't be like this, the envoy doesn't want to be like this, a certain person came to save the adult, why did he harm such and such a person?" ”

When Zhang Sheng heard this, he was a little puzzled, thinking that the person in front of him was just a fugitive, how could he save my life, and besides, I was not in any danger now, which was really a bit unbelievable.

Zang Yan saw that Zhang Sheng didn't believe it in his heart, and then said: "Don't be in a hurry, and listen to a certain person finish the matter, if it is unreasonable, it is not too late to hand over a certain to the emperor of the Han family." ”

"In that case, let's just say so, I'd like to hear what you have to say?" Zhang Sheng asked very seriously.

When Zang Tu heard this, he was very happy in his heart, and immediately poured a cup of warm tea for Zhang Sheng, and then said slowly: "The reason why the adults are reused in the Yan Kingdom is because the adults understand the stakes. ”

"The reason why the Yan Kingdom can exist for a long time is because the princes here have rebelled many times, Han Wangxin, Zhang Er, Chen Xuan, and my father Zang Tu are all the same, and they are not opposed, but they are slandered, and this persecution is just that the emperor of the Han family is worried about them, so the war continues for many years."

"Now the adults want to eliminate Chen Feng and others as soon as possible for the emperor of the Han family, it is really unwise, if Chen Feng and others are eliminated, then the Yan Kingdom can still exist alone? Afraid that the adults were about to become captives, the emperor of the Han family attacked Zhao Daiyan by unscrupulous means, and his intention was only to change the surname of the king of these three places to Liu Ye. ”

"Why didn't your lord let Yan Guo delay the attack on Chen Xuan and reconcile with the Xiongnu? If the war is delayed, it will be able to make Lu Juan the king of Yan for a long time, and if there is an emergency in the Han Dynasty, he can also use this to break away from the Han Dynasty and establish himself as a country. ”

When Zhang Sheng heard this, his face was erratic, and he wanted to come to Zhao Dynasty to change several kings, but no one was able to settle down, so it can be seen that the responsibility is not on the kings, but on Liu Bang's heart to get rid of the king with a different surname.

"What the public said is very true, a certain person is taught, but whether Chen Feng can make peace with the Xiongnu, isn't it also a question?" Zhang Sheng asked with some confusion.

"The Xiongnu are on par with the Han Dynasty, if Chen Feng has a little strength, he will not give up on nature, isn't that the case when he comes to Han Wangxin? Why is the public so worried? Zang Di said very indifferently.

After such a little bit of Tibetan selection, Zhang Sheng felt that this matter still needed to be re-planned, and hoped that the Xiongnu and Chen Feng would make peace, so that the land of the Zhao Dynasty would continue to fight, so that the land of Yan could still be preserved.

And although Zhang Sheng understood in his heart, Lu Juan didn't know what was going on, seeing that Zhang Sheng had not returned for many days, he couldn't help but be a little frightened, if Zhang Sheng and Chen Feng united, Yandi would be difficult to preserve.

Thinking about what Zhang Sheng did, he wanted to leave Yan Kingdom, if he didn't rebel, why did he gladly accept the order and go to the Xiongnu, the more Lu Juan thought about it, the more he felt that something was wrong.

So, he wrote a letter in the palace and asked Liu Bang to hand it over, which roughly meant that Zhang Sheng might rebel, and it was better to keep a close eye on his wife at home, otherwise there would be no way to contain this person.
