Seeing that the emperor's face was suspicious, Lu Zhen was not polite, stepped forward and picked up a small flag placed in the corner of the sand table, and then inserted it on the wooden city representing the location of Datong: "Your Majesty, please see, we can regard this flag as 10,000 military horses, or as 100,000 troops."

In this way, if there is a subsequent movement of troops, such as a local reinforcement, the same flag can be placed again. However, when it is necessary to mobilize a large number of border troops due to some unexpected events like this time, there is no need to repeat the relevant maps as before, and only a few small flags can be planted to show all the changes. As he spoke, he took another banner and planted it at the head of the city, but this time it was a small blue flag.

When he said this, the eyes of the Son of Heaven and the other officials showed a glint of joy. Zhu Qizhen slapped his palm and said in admiration: "Wonderful! It's a good idea to do it once and for all. In this way, the military headquarters and the local government will no longer need to spend too much time and life on mapping. ”

"Not bad." Lu Zhen nodded and continued: "Although my garrison has been transferred from time to time, the details of the mountains and rivers and other details of these border passes will not change, so this sand table can be used forever." That's not all, we can also use some small chess pieces or stones as armies of both sides and make deductions here. In addition, these forts can be moved, and if they are abandoned or built, they can be relocated at any time! ”

As he spoke, as if to confirm his remarks, Lu Jinshang forcefully pulled out one of the wooden buildings that had been used as a former enemy fortress from the sand table. It turns out that this building is put on a sand table with a wedge, which can be loaded and unloaded at any time, which is very convenient.

The Son of Heaven hurriedly stretched out his hand to take the fortress from Lu Jin, and after taking a closer look, he nodded again, and said again and again: "Lu Qing's design is really amazing!" Well, well done! ”

"Your Majesty has praised it falsely, and the minister has just entered his own duty." Lu Jinyu hurriedly bowed his head and said modestly. Then, he said: "In addition, there is another benefit in the sand table......

"Is it any good?" Zhu Qizhen couldn't help but scream, and hurriedly looked at Lu Jin, waiting for him to give him an explanation.

Lu Zhen really didn't disappoint him, and immediately said: "That is, this is much safer than the map, after all, it is so big, people with ulterior motives can't take it away at all." ”

"Not bad." The Emperor nodded his head in approval, for the turmoil a few months earlier had left a deep impression on him.

"Your Majesty, the old slave has something to say." At this time, Wang Zhen, who had been watching from the sidelines, suddenly spoke. At this time, his face had already returned to normal, not only did he not have the slightest hint of hatred and anger, but he was even quite happy to look at it, but he still had a little hostility in his eyes when he looked at Lu Zhen inadvertently.

However, the emperor couldn't see this, and he glanced at Wang Zhen very casually: "Mr. Wang, it's okay to say it." ”

"The old slave feels that this sand table does have a thousand benefits, but there is always a problem, that is, it is clear to anyone who looks at it, and it is much easier than ordinary maps." Wang Zhen said in a low voice.

"Huh? Isn't that a good thing? In the past, I felt a headache when I looked at those maps, but now this sand table is much clearer, and it is deeply in line with my intentions. Zhu Qizhen said with some puzzlement.

"Your Majesty, what the old slave thinks is that even the slave and maid can understand it, then this sand table can be easily understood by everyone, which naturally includes those with ulterior motives. Although Lord Lu said that it was not afraid of being stolen, it was afraid of being peeked at. ”

"Huh?" The Son of Heaven obviously hesitated when he heard this, and then the excitement on his face really decreased slightly, and he looked at Lu Zhen and said, "Lu Qing, have you ever considered this?" ”

Wang Zhen glanced at Lu Zhen again, feeling that although he couldn't defeat him this time, he could disgust the other party.

But the development of things disappointed the prince again, only to see Lu Zhen stretch out his hand to pull out the two flags that had just been planted, and then glanced at the other party with a smile, before saying to the Son of Heaven: "Your Majesty, this is what the minister wants to say, the last advantage of this sand table." The remedies marked on those maps are irrevocable, but on this sand table it is a different story. If you pull out the flag planted at the head of the city, who will know how many garrisons there are in the city?

"So we could have planted the flags one by one when we were discussing the military, and when everything was said and done, we could remove them, and the secrecy would be much more reliable than that of a map."

"Good! Lu Qing, you are really thoughtful in this sand table! This time, Zhu Qizhen was really happy, and while speaking, he happily stepped forward and patted Lu Jin's shoulder as encouragement.

This scene fell into the eyes of the ministers, and even those important ministers of the court were envious in their hearts. How could the Son of Heaven ever pat himself on the shoulder so affectionately, today is really unprecedented.

And Wang Zhen, this time he completely lost his spell, so he had to smile awkwardly and step aside.

Then, the emperor said: "I have accepted your sand table." This is the most satisfying birthday gift I have received since I ascended the throne, and I know that this is your loyal and patriotic heart, so let's say, how can I reward you? ”

The weight of these words is very heavy, generally speaking, the Son of Heaven wants to reward his subordinates directly decides, how can he ask the other party what he wants, which shows how satisfied and happy he is this time. Of course, such a statement is often the most difficult to deal with as a courtier, because no one can grasp the mind of a monarch, and he does not know what reward to ask for is the best for himself. Of course, such problems are not without solutions, such as-

"The minister did all this just to congratulate His Majesty on his birthday, and he didn't dare to ask for anything else. And it is not the work of the ministers alone to make this sand table, whether it is the relevant officials of the Ministry of War or those craftsmen, they have made great efforts, so if Your Majesty really wants to reward them, you can reward them. "Lu Jin's strategy of retreating is the best way.

Sure enough, the Son of Heaven smiled again when he heard this: "Lu Qing, you are too modest, I still remember the airship a few years ago, and I was really shocked at that time." Only if you can think of capable people can you innovate and continue to create surprising good things. Those who help you are certainly meritorious, but you are the first meritorious person, how can I not be rewarded for meritorious work and chill the hearts of the subjects of the world? ”

"This, since Your Majesty said so, the minister does have a small request, and I hope Your Majesty can grant it."

As soon as Lu Zhen said this, Hu Hu frowned slightly, but Wang Zhen was overjoyed. If he makes any excessive demands, although the emperor will definitely satisfy him now, he will naturally be a little unhappy afterwards, and it will be easier to make a fuss in the future.

"You said, as long as I can do it, I will not refuse." Without waiting for Hu Hu to give Lu Zhen a look, the emperor had already answered.

Lu Zhen hurriedly solemnly bowed his hand again, and then said: "The minister built this sand table, in addition to feeling the turmoil a few months ago, but also because he knew that it was not easy for the border soldiers to deal with the enemy. Therefore, the minister hopes to do a little bit of effort, and asks His Majesty to promote this sand table in the name of the imperial court to the world, and the minister will be satisfied. ”

"Huh?" The emperor was stunned when he heard this, and the other courtiers were also stunned. No one expected that he would make such a request as a reward, what kind of reward is this, it is clearly for the imperial court.

Hu Hui's face smiled again, and he glanced at Lu Zhen deeply, this young man really didn't let himself down. Wang Zhen lowered his eyelids and hid his disappointment.

After a long time, the Son of Heaven shook his head and said, "What kind of reward is this, even if you don't say it, I will let people spread it everywhere." It's like the airship......"

"Your Majesty, other ministers have nothing to ask for." Lu Jin hurriedly praised him.

But the emperor obviously didn't want to just forget it, but for a while, he really couldn't think of any proper reward. After all, he doesn't know much about Lu Jin. And the general financial rewards seem to be a little out of reach, should he be given the title of civil official?

Just when the Son of Heaven was entangled, Kuang Yu stood up and said, "Your Majesty, the minister has an idea. ”

"Kuang Qing, please speak."

"Although Lu Zhen is now a member of the staff, he is responsible for the position of Langzhong. And since the Shilang Naka Jibin left Beijing due to illness, this position has been vacant. In the opinion of the minister, it is better to promote him to Langzhong with this achievement, which is justified. ”

When the emperor heard this, he immediately nodded: "Kuang Qing's words are very true. Lu Qing listened to the seal ......"

As a result, such a sand table that took several months to make brought a lot of benefits to Lu Jin, not only did the emperor deepen his impression of him again, but also was promoted from the fifth-rank outsider to the fourth-rank langzhong, and at this time he was already qualified to wear the red official uniform representing high-level officials.

When this news became known to the courtiers a few days later, it caused quite a stir again. You must know that except for those military attachés who are hereditary or have made meritorious contributions on the battlefield, there are very few people in this dynasty who can become a high-ranking official of the fourth rank in their twenties. Even if they are young and talented, they have to go through several years of training to climb to the position of Lu Zhen today, and at that time, they were already over thirty-five years old.

It can be said that Lu Jin's rapid promotion this time has really aroused the eyes of too many people, and there are many criticisms behind the scenes. However, these voices of theirs are obviously useless, and the real threat is only the cronies and eunuchs beside the Son of Heaven.

To the surprise of many people, this time Wang Zhen did not speak out again, as if he had accepted the fact that he could not deal with Lu Jin.

Only the closest people around him knew that in fact, he temporarily let Lu Zhen go because he had another big thing to do. And this major event will soon cause a storm in the DPRK......
