In the early morning of the next day, Prince Dan simply packed his bags, carefully disguised himself, and secretly left Xianyang and fled back to Yanguo.

Since Prince Dan was holding the customs clearance token given by Lu Buwei, the journey was unimpeded. And on Xianyang Street that day, many people saw that Prince Dan was kidnapped by a group of big men, and everyone expected that he must have been beaten again, and it is estimated that he was lying in bed to recuperate in the past few days, so the court did not notice anything abnormal.

Prince Dan, who fled back to the Yan Kingdom, saw the light of day again, and the whole Yan Kingdom rejoiced, and the King of Yan held a grand welcoming ceremony for him.

King Yan is very old, and in recent years, he has been threatened by the Qin State, and he has been worried about state affairs all the year round, so he has become increasingly haggard and has long been like a withered tree. Now that the prince has returned, he feels at ease, so he hands over all matters in the country to Prince Dan.

After Prince Dan took charge of the Yan State, with infinite hatred for the Qin State, he was determined to fight against the Qin State at all costs, so he spared no expense to recruit talents, and for a time the world was full of heroes, including some outlaws, Jing Ke was one of the outstanding representatives.

Jing Ke was originally a ranger, strong in martial arts, affectionate and brave and ruthless, once only for a momentary battle of words, actually killed the other party's whole family, chickens and dogs did not stay, and then in order to avoid the pursuit of the government, he fled everywhere, and went to Yan State, heard that the prince Dan of Yan State was recruiting brave warriors, so he came to defect.

Therefore, Prince Dan soon noticed Jing Ke and had the intention to take it for his own use, so he took care of him in every way, accompanied by a car, drank wine, and gave him a thousand gold, Jing Ke was grateful, so he was desperate for Prince Dan.

On this day, Prince Dan and Jing Ke drank together in the mansion, and the wine was half-drunk, Prince Dan suddenly got up and said: "Since Dan met Brother Jing, he has always been a fellow friend of his heart, and he has no intention of being a master and servant, I don't know if I can introduce Brother Jing as a confidant?" Hearing this, Jing Ke hurriedly got up and replied: "The prince treats me like a mountain, and I am willing to go to the soup for the prince, and it is really a blessing for Jing Ke to be able to have fellowship with the prince."

When Prince Dan heard this, he immediately bowed down and said, "As for this, the junior brother has the courage to ask Brother Jing for help." Jing Ke hurriedly bowed down and saluted and said, "Jing Ke is obedient to orders."

Prince Dan slowly helped Jing Ke to get up together, and said excitedly: "Violent Qin has no way, poisoning sentient beings. I think that when I entered Qin as a hostage, the Qin people regarded me as a cow and sheep, and bullied me wantonly, which can be described as nine deaths. Fortunately, with the help of nobles, he finally escaped. Since the day he returned to China, Dan made a poisonous oath to eradicate the tyrannical Qin for the people of the world and return the people to a prosperous future. Therefore, I searched for loyal and brave men day and night, looking for an opportunity to assassinate the thief king of Qin, the king of Qin was killed, and the Qin country would be in chaos. Brother Jing is not only strong in martial arts, but also a man with lofty ideals in the world, and he is the best candidate for the assassination mission. After speaking, Prince Dan knelt on the ground.

Jing Ke panicked, and hurriedly held up the prince Dan and said: "The prince must not, the king of Qin has no way, everyone in the world will be punished, Jing Ke should stand up." Prince Dan clasped Jing Ke's hands tightly, and was so excited that he couldn't speak for a long time.

Preparations for the assassination proceeded quickly and in an orderly manner. In order to gain the trust and permission of the King of Qin, Prince Dan took the head of Fan Yuzhi, a general of Qin, as a greeting gift, and entered the fertile land of Yan State.

The place of farewell was chosen next to Yishui on the outskirts of Jicheng in Yanguo. Prince Dan specially asked his disciple Gao to gradually leave for Jing Ke. Gao Yuanli is the first person to build the world, his sound is melodious and long, sad and high-pitched, accompanied by the sound of desolate flowing water, Jing Ke can't help but feel a bleak and sad feeling in his heart, and can't help but murmur: "The wind is sluggish and the water is cold, and the strong man will never return."

Everyone present burst into tears when they heard the sound, and Prince Dan held his hand to see him off, reluctant to leave for a long time. Jing Ke bowed to the prince Dan three times, then quickly stepped on the saddle and walked away without looking back.
