Let's say that Jing Ke came to Qin State alone and handed over the national credentials. Prince Chu of Qin read the letter of state handed over by Jing Ke and asked Lü Buwei, "What does Lü Xiangguo think about this matter?" Lü Buwei replied: "Yan Guo has nothing to do this time, it must be a fraud, but the king doesn't have to worry, the ministers will arrange the disposal, and the king only needs to see people and receive gifts." Zichu was greatly relieved when he heard this, so he immediately ordered someone to arrange a meeting with him.

Jing Ke received an invitation from the eunuch in the post house that day. On this night, Jing Ke bathed and changed clothes, burned incense and prayed, and constantly wiped the dagger that Prince Dan gave him to assassinate the King of Qin-Fish Intestine Sword, this sword was made of fine iron, extremely sharp, and soaked in venom for 7749 days, extremely poisonous, and saw blood seal the throat.

That night, Lü Buwei was in the secret room of the palace to meet a mysterious man. I saw the man standing under the seat with his hands bowed, quietly waiting for Lu Buwei's instructions. Lu Buwei patted the man's shoulder and said softly: "Tomorrow you will disguise yourself as a imperial doctor and follow me into the palace, the law of the Qin State stipulates that you must not carry sharp weapons when you meet the King of Qin, so the medicine box is your weapon, tomorrow you must ensure that you hit with one blow, otherwise the consequences will be unimaginable." The man immediately knelt down and said, "Please rest assured, the little one is proficient in the art of throwing pots, and tomorrow will definitely ensure that nothing goes wrong." Lu Buwei nodded with satisfaction.

On the second day, Jing Ke was waiting outside the main hall early with Fan Yuzhi's head and the map of Du Kang. The king of Qin sat on the top of the main hall, and when the hundred officials arrived, he ordered the eunuch to lead Jing Ke to meet him.

Jing Ke got the reward, then strode to the main hall, to the palace, kneeling on the ground and making a big salute, and said loudly: "The king of my family wants to make friends with your country, in order to show his sincerity, the king specially ordered me to present the head of Fan Yuzhi, a rebel general of the Qin State." After speaking, Jing Ke raised a wooden box high, and the eunuch next to King Qin hurriedly went down to the palace to take it, held it to King Qin, and slowly opened the wooden box. After that, he raised his head and said to Jing Ke: "The strong man has worked hard, and the widow will be rewarded."

Jing Ke bowed to Xie En, thanked Enbi, Jing Ke said: "The king of my family also ordered the villain to serve the land of the governor, hoping that the two countries can stop the army and form a good alliance between the two countries." After saying that, Jing Ke held a roll of sheepskin in both hands, walked forward slowly, and when he got closer, the eunuch in front of the palace stretched out his hand to stop him. Jing Ke stopped and said: "The villain knows the rules, but because there are some places on the map that need the villain's guidance, he has to get close to the display, and I hope that the king will approve it." King Qin waved his hand and motioned for the eunuch to retreat, so Jing Ke slowly unfolded the map a few steps away from King Qin.

Jing Ke unfolded the map and explained the mountains and rivers on the map one by one, and King Qin stared at the map intently, with a hint of joy and greed on his face from time to time. Finally to the end of the map, King Qin seemed to be still unsatisfied, suddenly Jing Ke green muscles burst out, a pull out of the fish intestine sword hidden at the end of the map and stabbed at the King of Qin, King Qin was stunned on the spot, His Royal Highness and the ministers were already frightened, seeing that the dagger was about to be inserted into the heart of King Qin, at this extremely critical moment, suddenly flew from His Royal Highness a medicine box, just hit the dagger away, and the fish intestine sword was obliquely inserted into the column of the main hall.

Seeing this, Jing Ke was in a hurry, and rushed towards King Qin like crazy, and King Qin hurriedly retreated. In the urgency, Jing Ke was tripped by the medicine box, taking advantage of this opportunity, King Qin quickly pulled out the sword he carried, Jing Ke wanted to get up, King Qin had already slashed down with a sword, right in Jing Ke's shoulder, Jing Ke couldn't bear the pain, and fell again, at this time, the guards outside the palace had already heard the sound and rushed to the palace, so they chopped Jing Ke into meat sauce.

A false alarm ended, King Qin threw his sword to the ground, and the whole person sat on the seat, his face was bloodless, his hands kept trembling, and he couldn't say a word. Seeing this, Lü Buwei immediately stepped forward to support King Qin, and then turned to his ministers and shouted: "King Yan is shameless, he wants to assassinate my king, he really deserves to be killed."

At this time, King Qin had to wake up and roared angrily: "The widow vows to destroy the Yan Kingdom." After saying that, he turned his eyes to Li Xin and said: "General Li obeys the order, and the widow orders you to be the general of the Yan Dynasty, send 500,000 troops, and set out on the same day, and you will definitely take the head of the king of Yan." Li Xin stopped talking after hearing this, so he had to say heavily: "The last general will take the order."

Li Xin was ordered to retreat, Lu Buwei waved his hand to signal the ministers to retreat, and the ministers rushed out one after another, the experience just now was like a dream, and many ministers still staggered out of the palace gate.

Lü Buwei ordered the eunuch to help King Qin go back to Zhao Ji to rest. When King Qin saw Zhao Ji, he hugged Zhao Ji tightly and cried bitterly: "The queen almost can't see this king today." Zhao Ji hurriedly stroked his back to comfort, King Qin gradually settled down, Zhao Ji tidied up the bed tent, served King Qin to sleep, King Qin will not fall asleep.
