In the 50th year of King Zhaoxiang of Qin, Qin led the Qin army of 100,000 to besiege Handan City, besieged the city for more than half a month, Zhao sent an envoy to Yan State, Qi State, South Korea to move rescue troops, and the three countries gathered 60,000 troops to Handan to relieve the siege of Zhao State. Before the reinforcements of the Three Kingdoms arrived, Lü Buwei sold his wealth according to Li Si's plan, bribed Gongsun Qian, the minister of Zhao State, who was monitoring Gongzi Yiren, and the generals guarding the south gate of Handan City, and rescued Yiren from Handan City in the crowd of people out of the city when the city gate was about to close at night. After Wang Ji learned the news that Lü Buwei had succeeded, he also collected his troops and returned to the Qin realm. Because it was too eye-catching to carry his wife and a child, he did not bring Zhao Ji's mother and son in this rescue operation, and Yiren promised the mother and son when he left, and after returning to Qin to settle down, he would send someone to pick up Zhao Ji's mother and son to return to China.

Zhao Ji's mother and son waited in Handan City for ten years before they waited for someone sent by the king of Qin, who had changed his name from Yiren to Zichu, to bring him back to Qin. After returning to Qin, Zhao Ji was crowned queen, and his son Yingzheng was made the crown prince of Qin. At this time, Lü Buwei was already the minister of the Qin State, the Marquis of Wenxin, with 100,000 subordinates, and was in charge of the government. Li Si was recommended by Lü Buwei, and Prince Chu of Qin hired him as a prince to teach Prince Yingzheng and Prince Chu's second son Cheng Cheng in the palace to study. Later, due to Meng's meritorious attack on Korea, the king of Qin took Meng's two grandsons, Meng Tian and Meng Yi, into the palace and listened to Li Si's lectures with Yingzheng and Cheng Ling.

When Meng Tian and Meng Yi first met Yingzheng, who was the same age as themselves, they seemed to be familiar with each other, and the three of them were very able to talk together. Ying Zheng was very interested in the customs of the Qin State, and the Meng brothers also felt fresh about the life of the Zhao State, but Cheng Cheng couldn't play with the three of them. Cheng Cheng is not interested in this brother who is two years older than him, and even has some hostility, because his mother said to himself that he is likely to be the king of Qin in the future, and now he suddenly has an extra brother, which threatens his throne, as for the two brothers of the Meng family, Cheng Cheng has never seen it before, although they both live in the aristocratic life circle of Xianyang City, but one grew up in the palace, and the two of them grew up in the military camp, so they don't have any common hobbies at all.

Meng Tian and Meng Yi began to learn things under the teaching of Li Si since they entered the palace, but Meng Tian didn't like to go to class, he liked to listen to Li Si tell the story of his trip to the Six Kingdoms, but Meng Yi was very interested in the Confucian classics, and Li Si also liked the two brothers with a strong desire for knowledge. Since becoming the prince of the palace, Li Si got rid of the life under the fence of the Lu Mansion, and he began to study the statecraft that the teacher had taught, because in the future, whether it is Yingzheng or Chengcheng, the throne of the Qin State must belong to one of the two of them, no matter who sits on the throne, he is the first minister to support the dragon, and there will definitely be a place among the ministers of the Qin State in the future.

On this day, Meng Tian grabbed Li Si after Li Si finished his lecture and asked: "Can Mr. teach me the art of war?" I am not interested in the Confucian doctrine classics that Mr. taught, I don't want to be a civil servant like my brother in the future, I want to lead the troops to the battlefield, so I implore Mr. to teach me the art of war." ”

After listening to Meng Tian's words, Li Si smiled, "When you entered the palace that day, your father told me about it, you and Meng Yi have completely different personalities, he likes my Confucian articles, you like to play with guns and sticks, you two brothers are indeed very good." However, your grandfather and father are all famous military generals in the Qin State, and there is also the old general Wang Jian here, you don't actually have to go to the special study of military books, these elders of yours are the best military books, you just follow them to study. Besides, my Confucianism pays attention to governing the country with etiquette, and the art of war is not my specialty, and I can't teach you. ”

After listening to Li Si's words, Meng Tian said: "My grandfather, my father, and Grandpa Wang, they all think I am young, and they never take me to lead the troops to fight, but they only let me listen to them in the barracks to talk about the arrangement of troops or something, although I can understand, but I still want to lead the troops to fight in person." ”

Li Si said: "Qin Law stipulates that men can enlist in the army after the age of thirteen, and you still have two years to go, of course you can't lead the troops to fight by yourself, so you should follow your father and learn to fight well." When you have actually joined the army, you can tell your father, and if he does not agree, I will say a few good words for you, and perhaps your father will agree. ”

After hearing this, Meng Tian said okay, then bowed to Li Si and walked towards the gate of the palace. Meng Yi was waiting for him at the gate of the palace, and when he saw Meng Tian coming out of the palace, he hurriedly greeted him and asked him why he went, as soon as the lecture was over, he couldn't find anyone. Yingzheng almost mobilized the palace guards to find him.

Meng Tian said: "It's okay, I don't know a little bit about the place, so I went to ask Mrs. Li for advice." Okay, I'm back, let's go home. After speaking, he pulled Meng Yi into the carriage and walked towards Mengfu.

In the third year of King Xiang of Qin Zhuang, Prince Chu of Qin died of illness, and the crown prince Yingzheng was established as the king of Qin, the second son Chengcheng was the marquis of Chang'an, and the queen Zhao Ji was the queen mother.

The Six Kingdoms learned that King Xiang of Qin had died of illness, and that the new King of Qin had just turned thirteen years old and was a milky child, so under the persuasion of Wei Wuji, the son of Wei, Xinling Jun, united with Zhao, Han, Chu, Yan, and Qi, and the Six Kingdoms jointly sent troops to attack Qin. The Qin State is in the special period of the alternation of royal power, and the whole country is panicked for a while, although the city of Xianyang is still calm on the surface, there are already many wealthy traders inside who have begun to slowly pack up their belongings and prepare to quietly leave the Qin State.

In the palace of King Qin, the thirteen-year-old Ying Zheng sat on the throne and glanced at the civil and military officials of the Qin State who were standing in two teams below, "The widow heard that the Six-Nation Alliance Army attacked my Qin State, and now it is outside the Hangu Pass, I don't know who can lead the troops to meet the enemy?"

Lü Buwei stood at the head of the civil officials, and when he saw Yingzheng asking himself, he replied: " Qiyu Wang, although the number of the alliance of the six countries is large, but in essence, they are all in order to want to divide the land they occupied before my Qin State will come together, my Qin State since the filial piety, experienced King Huiwen, King Wu, King Zhaoxiang, and the first king Zhuang Xiang, every King of Qin has been in office when the Six Nations Alliance joined forces to attack my Qin State, but my Qin State is indeed getting stronger and stronger in one war after another, and the land of my Qin State is also getting wider and wider。 Therefore, this time the six countries attacked my Qin country, the king did not need to worry, he only needed to send a general to sit in the army to calm the army's heart, and then I arranged for the envoy to lobby between the six countries, and it would definitely be the collapse of the six countries alliance. ”

After listening to Lu Buwei's words, Yingzheng clapped his hands and said, "Okay, just follow the words of the middle father." In this case, the old general Mengfu, I wonder if the old general can lead the army to the expedition this time and strengthen the heart of my Qin army?"

When Meng Fu heard Yingzheng shouting to him, he happily stepped out, "Enlighten the king, the king's order, and the ministers must obey." What's more, there is also Lu Xiangguo's clever plan, and the minister promises that he will never let the armies of the six countries occupy the slightest land of our Qin State. ”

"Well, the old general is really brave, and the widow is waiting for the old general's good news in this palace. ”
