After reading the letter from Guan Fei, the captain ordered his soldiers to quietly open the city gate, and after Wang Ao and the others entered the city, the captain handed over the Yan army uniforms that had been prepared, and everyone changed into their uniforms and continued to walk towards the city.

It turned out that this Yan military captain was also a member of the Qin army's intelligence network, but he was humble in the Yan army, in addition to collecting some needed information, he could only help the Qin State in this way, and the generals of the Qin army also knew that although there was an undercover agent there, if he opened the city gate and attacked, it was very likely that the whole army would be annihilated in Liaodong City.

Wang Ao led his subordinates straight to An Guohou's mansion, came to the door and annoyed the doorman to inform the old man of the visit, An Guohou sat up from the couch and sat up to give an order to invite him into the mansion.

Seeing that the person who came was Wang Ao, Ji Tong had already guessed his intention, and said to him: "I didn't expect that the old man turned out to be Brother Wang, and I won't say too many polite words on all sides, Brother Wang came this time on the orders of King Qin, and if he can't take Liaodong County, he plans to win without a fight."

"Brother Ji, although this is the case, but isn't this what you want to see, you also want to preserve the ancestral foundation of the Yan Kingdom and the Sheji Sect Temple, you definitely don't want these to be destroyed in the war."

"Wang Ao, have you already investigated me, how do you know that I want to see this."

"Lord An Guohou, you and I have been classmates for many years, don't I know you, now you know what I have done to walk in line with you, how to choose, you can do it."

After listening to what Wang Ao said, Marquis An nodded and ordered a few people to settle down first, and then went to the inner palace of King Yan to meet alone.

After seeing King Yan, Marquis An gave out his original point of view, and still advocated that he should surrender to the Qin army to save the ancestral temple and the people, but King Yan shook his head and insisted on fighting to the end.

Ji Tong failed to persuade him to return to his mansion, and Wang Ao said to him: "It seems that King Yan still thinks that he can win, and now I am afraid that he can only put pressure on him again, but you can rest assured, the Qin army will definitely not attack the city for the time being."

After receiving Wang Ao's instructions, Guan Fei took advantage of the night to walk to the top of the city tower, and with the help of the undercover agent, he wanted the Qin army outside the city to transmit the signal.

Receiving the signal from the city, Cao Ji arranged five first-boarding stormtroopers to advance to the city of Liaodong and use ropes to ascend the city through the darkness.

When the defenders heard the news, they hurriedly fired back like locust-like arrows, and Cao Ji saw that the siege was blocked, so he called in a catapult, which had a limited range and could only hit the city wall fiercely, but it had caused a lot of psychological burden to the defenders.

King Yan saw that the Qin army was still so big in the night attack on the city, and he was shocked and transferred all the forbidden troops to the city to defend, and the fierce battle lasted for half an hour, and the Qin army was finally forced to retreat.

Early in the morning, Ji Tong entered to see King Yan and said: "King, I just got the news that King Qin has transferred 100,000 troops from China and is about to arrive at the city of Liaodong.

"King, what An Guohou said makes sense, after all, if you stay in Qingshan, you are not afraid of no firewood, why don't you descend to Qin State first to save your life and strength."

Hearing that Lord Yu actually said this, Yi Hou pulled him aside in some surprise and whispered: "Haven't you been thinking about the throne for a long time, and now that Zongmiao has said such a surrender, even the country is gone, how can you be king."

"Ji Qian, I said that there is only a mess left in Yan Country at the moment, you look at this city that is still full of holes, how can I claim the king and dominate Yan Land, it is better to let Qin State occupy it first, and then try every means to take Yan Land back."

Seeing that Lord Wu actually said this, he only proceeded from his interests at all, and did not consider himself who was also worried about the throne at all, Yi Hou's heart was full of anger at this time, and he thought: "No matter what, you can't let the Qin army enter the city, otherwise it will be difficult to recapture it."

Seeing the anger that Yi Hou had already highlighted, Lord Yu sneered happily, even so, Yi Hou still couldn't say anything about continuing to resist Qin.

was already suffering from the continuous destruction of the Qin army outside the city, but after An Guohou and Lord Wu said this, King Yan completely shook his confidence and ordered Ji Tong to take full charge of the matter of asking for surrender.

Anguo Marquis's Mansion

Guan Fei asked Wang Ao: "I really don't know what the above thinks, isn't it okay to send troops directly to conquer Liaodong County, why do you have to go around such a big circle, it's really troublesome."

"General Guan, don't you know that attacking the heart is the best, if you don't eradicate the hidden danger in the center of Yan Kingdom, then even if you destroy them, you won't be able to completely conquer them, so only this is a good policy, so it will be easier to wipe out Prince Yan and Liu Xiang and their party."

After listening to what Wang Ao said, Guan Fei secretly said in his heart: "Such a good prescription is really a clever plan, and you can also use this method in the future, which will definitely reduce the burden."

At this time, one of Wang Ao's confidants came to report: "The envoy of the acting king Zhao Jia asked to see the king of Yan, and he must have important news to present, but I managed to delay and stop him."

Wang Ao hurriedly walked up to the envoy of the king, and pretended to be the regent of the Yan State in exchange for trust, so that he took the initiative to hand over the letter box to himself.

opened the letterbox and took out the letter, Wang Ao quickly read it and handed it to Guan Fei, saying: "I thought it was very important information, but I didn't expect it to be just some useless language, and told him to send it to King Yan."

After reading it, Guan Fei pointed to the letter and said: "If you want to get rid of Prince Dan, this letter will play a big role, I have a plan, I will make that Prince Dan die without a place to be buried, I heard that Lord Wang is also a master of calligraphy, it must be very easy to imitate other people's handwriting, this matter still needs to be troubled by adults."

Then, Guan Fei told Wang Ao about the plan in his heart, Wang Ao nodded and admired his idea, so he immediately took out a blank and clean bamboo slip, wrote some words on the bamboo slip, and then stuffed the bamboo slip into the letter box and handed it to the messenger, ordering him to present it to King Yan.

The messenger did not know that the letter had been replaced with something else, so he happily went to the palace of King Yan and presented the letter.

Knowing that the letter of the king of Dai arrived, the king of Yan opened the mailbox and took out the letter, and after reading it quickly, he called the marquis of An Guo and said to him: "The situation of the country is not optimistic, the king of the country is trying to make peace with the state of Qin, he said in the letter, the Qin army has suffered for a few days because of the prince Dan led the army to counterattack, Jing Ke's assassination of Qin has made the king of Qin angry, and the king of Qin has also issued an ultimatum, and the main culprit Jing Ke can be spared by the other officials and nobles of the Yan State, otherwise he will slaughter Liaodong City."

"King, since this is the case, we should give up one person to keep everything, or you will really become a sinner in the Yan Kingdom, and I think the prince should also have the consciousness of dedication."

Hearing Ji Tong's words, King Yan immediately summoned Lord Wu to discuss it......
