After settling Li Si's residence in the palace, Wu Zhan and Li Si had a rare happy get-together.

"Brother Wu, the last time I left you to join the palace guard, there was no news, why did you suddenly become the king's chamberlain?" Li Si poured a bowl of fragrant tea for Wu Zhan and couldn't help but ask.

"What kind of servant is not an inmate, I am naturally not a real eunuch."

Wu Zhan peeled a peanut and threw it into his mouth, and said vaguely: "I had a relationship with the king when I was young, and when I was on duty, I was recognized by the king, so I was transferred to my side." ”

"You're not a eunuch?" Li Si exclaimed.

"Of course not!"

Wu Zhan explained: "Think about it, in addition to the eunuchs around King Qin, there are palace maids, in addition to pretending to be a chamberlain, what capacity can I always accompany the king?" ”

Wu Zhan's words are false and real, but they are also in line with common sense. Li Si finally understood the reason, and couldn't help laughing: "In the imperial study just now, I still blamed myself for sending you to the palace guards, causing you to become a eunuch, haha, it seems that I was too worried." ”

"You are indeed too worried, but your performance in the temple today is really an eye-opener for me, admiration and admiration." Wu Zhan couldn't help but praise Li Sidao.

"Brother Wu is lifted up!"

Li Si thanked him and said: "If there is no Brother Wu for his kind words in front of the king, I am afraid that Li Si will have to spend the rest of his life in the Prime Minister's Mansion......"

"Brother Li is too modest, in my opinion, Brother Li is like the buried gold, sooner or later it will shine!" Wu Zhan complimented.

Everyone loves to listen to compliments, and Li Si is naturally no exception.

But he saw Wu Zhan suddenly show his solemn face, and said: "Brother Li touched me a lot by what he said today, my father used to be a spy of the Qin State, and now I also want to inherit my father's mantle and become a spy of my Great Qin, dividing the monarchs and ministers of the world, so as to help my Great Qin rule the world." ”

Li Si couldn't help but look at Wu Zhan differently when he heard this, and only listened to him: "But becoming a spy is not an easy task, and it is also a dangerous life, can you think about it?" ”

"My father asked me the same thing, and now I can tell you with certainty that I thought about it!" Wu Zhan cut the railway.

When he joined the Netherworld Guard with Dongfang Yun, it was originally just to protect Yingzheng personally, but now if he can follow his father's will, it can be regarded as fulfilling his father's wish.

Seeing that Wu Zhan answered seriously, Li Si couldn't help but pat Wu Zhan's shoulder, nodded and said, "It is precisely because of a hot-blooded man like you that Great Qin can rise among the nations." ”

"How to become a qualified spy, please teach me." Wu Zhan bowed his hand and begged.

Li Si smiled slightly, stroked the black whisker on his chin and said: "The spy was first recorded in the "Zuo Biography", which was said to be in the Xia Dynasty, and it has a history of thousands of years. Originally spies were only used to spy on and obtain enemy intelligence, but now they have far gone beyond the role of espionage and intelligence, and also include spreading rumors, bribing or cultivating espionage personnel from other countries, assassination, and rebellion. ”

"Sir's words are very similar to what my father said back then, and my father told me that spies can be divided into causes, interiors, anti-divisions, living rooms, death rooms, etc., and the people in the middle are also selected from the villagers of the enemy country; Officials who inspire against enemy countries; The Rebels use the spies of the enemy to our advantage; The deceased uses his death to provide false information to the enemy, so that the enemy believes and suffers losses; A living person is a person who returns alive after completing a mission. Wu Zhan added.

Li Si nodded and smiled when he heard this, and said, "It seems that Ling Zun is not only a spy, but also a very senior spy!" If there is an opportunity in the future, Li will definitely come to the door to ask for advice. ”

Wu Zhan's expression darkened when he heard this, and he said: "My father died four years ago in order to save the king's mother and son from the assassins of Zhao State......

"I'm sorry!"

Li Si put away his smile and said solemnly: "I didn't expect Brother Wu to be a martyr!" ”

Wu Zhan smiled miserably and said: "If one day, all the countries are included in the Qin Tu, there will be no more disputes in the world, everyone will live and work in peace and contentment, and my father will be very happy if he has a spirit in the sky." ”

These words deeply touched Li Si, thinking that he was a county official in Shangcai, and he could have spent a dull and happy life with his wife and children, but when he thought of the fact that there are wars in this world all the time, and countless families have become separated and broken because of the war, Li Si can't bear it.

So he resolutely said goodbye to his parents and wife, worshiped under Xunzi alone, studied hard, traveled to other countries, and naturally could help one country unify other countries, so as to end this troubled era of war for hundreds of years, and return the world to peace......

"Brother Wu, let me ask you, how much money does it cost to fight between countries?" Li Si asked suddenly.

"This ...... I think about it, if you want to fight a national war, in addition to paying a huge amount of money and equipment, you also have to bear the food and grass of hundreds of thousands of troops every day, and provide pensions ......for the dead soldiers," Wu Zhan counted with his fingers crossed.

But Li Si smiled and said: "Take the Battle of Changping in Qin and Zhao seventeen years ago, when the Qin army sent all men over the age of fifteen to the battlefield, with more than 600,000 troops, this war lasted for five months, and finally the Qin army suffered more than 200,000 casualties and won the final victory of the war." And the Zhao army suffered 500,000 casualties, which seems to have gained a lot, but the losses of the Qin State are also astronomical! ”

"I'll calculate an account for you, the Qin army of 600,000 people, regardless of the difference between officers and military branches, each person will be calculated according to three catties of millet per day, and the daily military rations alone will consume as much as 1.8 million catties, about 150,000 catties, and the market value of each bucket of rice is three taels of silver, that is 450,000 taels, and in five months, the cost of military rations alone will need 20,000 taels of silver!"

"If you add the differences in military branches, the cost of weapons, armor, horses, and the salary of the army, after this battle, the Qin State will have to spend at least 100,000 taels of silver!"

"Oh my god!"

Wu Zhan couldn't help but exclaim: "So much for 100,000 taels of silver? ”

Li Si said lightly: "Of course, this is just an estimate, and the actual cost is only a lot more!" ”

"That's terrifying, isn't it?" Wu Zhan had never imagined that a big battle would cost so much money.

"That's why Sun Tzu has a cloud: 'Go up to the army to plot, then to attack the enemy, then to attack the army, and then to attack the city.'" ”

Li Si continued: "The idea of espionage that I advocate can play a huge role with only one percent of the war budget, which is naturally the most cost-effective. ”

"But what if the enemy doesn't love money?" Wu Zhan asked curiously.

Li Si took a sip of fragrant tea, moistened his throat and continued: "You should remember that human nature is inherently evil, and people will eventually have weaknesses, some people are greedy for life, some people love money, some people are lustful, and some people are jealous...... As long as you can catch the person's weaknesses, you can make them work for you. ”

"Mr.'s knowledge and insights made Wu Zhan admire him so much." Wu Zhan praised from the bottom of his heart.

"Hehe, my shallow opinion can be displayed in front of you, compared to my senior brother Han Fei, I am still far behind!" When it came to Han Fei, Li Si's eyes had a complicated look.

"I'm afraid that Mr. is too modest, if there is someone in this world who is more powerful than Mr., I'm afraid that this person is already inhuman, I'm afraid that he has become a god!" Wu Zhan said with a smile, he really didn't believe that there was anyone in this world who was more knowledgeable and intelligent than Li Si.

Li Si shook his head and smiled, noncommittal about this, but listened to him: "Brother Wu has such ambitions at a young age, Li admires him." But according to the current situation, the king of Qin is still young, why don't you stay by the king's side, first help the king build a spy system within the Qin state, and keep abreast of the movements of the ministers, so as to help the king smoothly govern himself? ”

"I don't quite understand what Mr. means, so please make it clear." Wu Zhan sat up straight and begged for advice.

Li Si secretly said that the son can be taught, so he said: "The king of Qin is now young, and the government is jointly controlled by the queen mother and Lu Xiang, this situation will take eight years, during this period, the royal power will fall, the ministers are suspicious, and things that threaten the royal power may occur at any time." Li Si believes that the top priority should first ensure the smooth administration of the king. ”

"But now that I have a gentleman, I am inferior to him in terms of mind and experience, so why does the gentleman want me to take charge of this matter?" Wu Zhan asked puzzled.

"Hahaha......"

Li Si laughed and said: "You also said, I only have the brains and experience, besides, I just came to King Qin from the Prime Minister's Mansion, and King Qin still doesn't trust me enough, plus I am still a secret spy planted by Lu Xiang on the king's side, many things are inconvenient to do, so no one is more suitable to do this than you." ”

Wu Zhan thinks about it, it makes sense, if he is responsible for building the spy coordination in the Qin Palace, he will naturally no longer need to play the role of Xiao Liuzi, the inner servant, and he can also turn from light to dark, coupled with the support of the Netherworld Guard forces, he will definitely be able to succeed.

Thinking about this, Wu Zhan bowed deeply to Li Si and said respectfully: "According to Mr. Yan's words, Wu Zhan is willing to give it a try." Please give me more advice! ”

Seeing this, Li Si hurriedly returned the salute, and said humbly: "Brother Wu is too modest, to be honest, we hit it off at first sight, and we have the common ideal of assisting the virtuous monarch to dominate the world, so let's work together to help the king achieve a great cause." ”

Winter goes to spring, and everything is renewed.

King Qin suddenly had a long history named Li Si next to him, it is said that this person is from the Prime Minister's Mansion, and anyone with a discerning eye knows that this person must be an agent sent by Lü Buwei to spy on King Qin.

Some people say that he offended Lü Buwei and was secretly executed, some people say that he violated the taboo of the Qin Palace and was killed with a rod, and some people say that he accidentally fell into a pond and drowned...... In short, all the accounts finally named Xiao Liuzi as dead. Who would bother with the life or death of a chamberlain?

In a deserted palace in the depths of the Qin Palace, there were several men standing at this time, all of them wearing leather pockets and black scarves covering their faces, revealing only a pair of eyes. The black leather armor blends with the night, and the sharp eyes communicate with death.

They are Wu Zhan's newly established 'net' organization under the order of Yingzheng, they hide in every corner of the Qin Palace in various identities, or hide among the generals of a group of princes and ministers......
