The spy prisoner hid Li Jinglong's letter under his underwear, and only then did he evade the inspection of the Northern Army, and it was not found that he was carrying the letter of the commander of the Southern Army.

When night and moon fell, the captive slowly opened his eyes and looked around, and found that the soldiers were all asleep, and occasionally a few patrolling sentries passed by, but they were not airtight.

He carefully observed the timing of each patrol and the time of exchange, and after calculating the gap, he seized this opportunity and quietly slipped into Zhu Song's camp.

At this moment, Zhu Song was drinking sullen wine in his tent, his face was gloomy and unhappy, and the captive was even more convinced when he saw Zhu Song like this.

"Your Highness, the little one is here!"

As soon as Zhu Song looked up and saw that it was a small soldier, he feigned anger and said.

"What do you do? Who let you into the king's tent, and the king of Yan sent you? Damn, Lao Tzu is a partial general of the army, why does he even have to drink a drink? Get the hell out of here! ”

The little soldier hurriedly walked into the camp tent, and after making sure that Zhu Song was the only one in the camp, he whispered to Zhu Song.

"Your Highness, there is a letter to be handed over to Your Highness, please read it carefully!"

The little soldier said and unbuttoned his pants, and took out a piece of letter paper from it, Zhu Song frowned and looked at the letter, and said in disgust.

"What did you pull out of your trouser pocket? Is it the toilet paper that you open when you go to the toilet? Are you humiliating the king, believe it or not, the king took off your head? ”

The little soldier was startled when he heard this, and knelt down for Zhu Song with a plop.

"Your Highness probably doesn't remember that Xiaoxiao himself is the Kaiyuan Army, this time he followed His Highness to Beiping, everything that happened was known below, and he knew that His Highness had been greatly wronged, so he ...... So here is a way out for His Highness! ”

"Your Royal Highness, Li Jinglong, the marshal of the imperial court's Northern Expedition, knows that His Royal Highness has been treated unfairly by King Yan, so King Yan said before that he shared the world with His Royal Highness, and now he hasn't won the world yet, this King Yan just did this, let alone the small one, even Cao Guogong can't stand it!"

"So Cao Guogong specially sent a small one to send this letter to His Highness, as long as His Royal Highness can cooperate with Cao Guogong and catch King Yan, then Cao Guogong will definitely say a few good words for His Highness at His Majesty, and if you want to come to Your Highness to make meritorious contributions, the court will never be unfair to Your Highness!"

Zhu Song thought that he had finally taken the bait, but on the surface, he deliberately pretended to be surprised and suspicious.

"Do you mean to say that Cao Guogong found you and asked you to bring a message to this king, saying that he can help this king in the underground with a few good words, and can make His Majesty forgive me, as long as I can catch King Yan?"

The captive nodded.

"Yes, Your Highness, we are all loyal to you, you have received so much unfair treatment from King Yan, and you are very angry when you look at it, I think we stayed in Kaiyuan at the beginning, and we didn't get involved in this matter, and now we are living a life of abundant food and clothing!"

Zhu Song pretended to wipe a handful of sweat from his face, and said with some hesitation.

"But since this king has already agreed, he wants to serve the heavens with King Yan, and now this king is going back on his word, isn't it a breach of trust?"

"Your Highness, where is your dishonesty in others, it is clear that King Yan is dishonest in the first place! Your Royal Highness, think about it, even if we defect to King Yan, King Yan really won the world, what can the result be, now King Yan is like this to His Highness, he has won the world, won't he be more suspicious of His Highness when the time comes? ”

"Your Highness, think about it, King Yan succeeds, he is the emperor, if he wants to harm His Highness at that time, then he is not a hundred reasons, in short, Your Highness, even if you think about it for yourself, you can't just be wronged along the way, now there is a chance to turn back in front of Your Highness, why don't Your Highness turn back?"

Zhu Song looked at the letter for a long time, put it on the table, and then paced slowly in the tent.

"What you say makes sense, now he treats me like this, if he really wins the world, when he becomes the emperor, there will be no brother like me who helped him rebel, and even he will be jealous of me because of this matter!"

"Yes, I can't make a mistake like this, but how can I contact Cao Guogong now, you were exchanged for prisoners today, how can this king write to him to discuss when to raise troops to capture King Yan?"

The captive was also stunned, but at this time, he also knew that he must not retreat, because once he retreated, he would be busy for so long.

If this matter stops, not to mention His Royal Highness, he has been looking forward to the uncle for several days, as well as the glory and wealth, all of them will come to naught.

"Your Highness, you are not talented but you are familiar with the arrangements in the army, if Your Highness thinks it is feasible, this matter will be handed over to the small one, even if the small one sharpens his head, he will send this letter to Cao Guogong's hand!"

After Zhu Song heard this, he pretended to look at the soldier gratefully and patted him on the shoulder.

"Why didn't this king see that there were such heroic and loyal soldiers like you under the original king's account, if you help this king succeed this time, as long as this king is forgiven by His Majesty, this king will definitely personally give Your Majesty the credit for your merits!"

This soldier was amused when he heard it, if His Royal Highness could also give him a few kind words in front of the emperor, then he was not just as simple as an uncle, no matter what he said, he had to make a marquis, right?

"Humility is His Royal Highness, and he will not hesitate to go to the soup and fire!"

Zhu Song wrote a letter and handed it to the soldier, asking him to go to the southern military camp tent and hand over the letter to Cao Guogong and Li Jinglong.

In the letter, Zhu Song had even written how to deal with King Yan.

Let's just say that there is a shortage of food and grass in the army, as long as Li Jinglong personally leads the army to bypass the camp tent of the northern army to attack Beiping, then Beiping is empty and will inevitably be lost!

At that time, Zhu Di could not go back to Beiping City. If you can't prepare the army, it's not like closing the door and beating the dog will make him go and never return!

Don't talk about how the little soldier received the letter and kept it safe, he stuffed the letter into his crotch in the same way, and then took advantage of the night to really ask him to sneak out of the camp.

After the little soldier left, Zhu Song's eyes suddenly became extremely clear, and at this moment, a person also came out of Zhu Song's big tent, this person was none other than the general under King Yan, Zhu Neng.

"Your Highness, my Highness has already made arrangements over there, and now my Highness is already near Beiping, as long as Li Jinglong leads the army to bypass our army's camp tomorrow, he will have no good fruit to eat..."
