Zhen Guogong was busy this time, and it was already afternoon.

The tiredness after the hangover gradually came up, and Zhen Guogong took a short nap before ordering someone to invite Han Yan over and state his "little opinion".

He said that this newly acquainted little junior brother was a "small opinion", but he was afraid that it was actually a very beneficial golden and jade good word in the army, so he naturally had to be fully prepared to come to "be taught" again.

Han Yan soon received the order to the winner's account.

Without waiting to see the courtesy, Zhen Guogong smiled and said: "If the junior brother has any opinion, just say it." ”

Han Yan saw that the other party was dealing with him as a personal relationship, so he no longer adhered to the rules of the commander's subordinates, and said with a smile: "I also want to borrow senior brother's pen, ink, paper, and inkstone." ”

Zhen Guogong nodded, got up and left from the front of the desk, and said with a smile: "Please." ”

Han Yan bowed his hand slightly, calmly sat down in front of the desk, laid paper and ink, and carefully sketched with a pen.

In front of the case, Zhenguo was silent, observing carefully.

On the white paper, the shape of the mountain stream gradually emerged, and if you looked closely, it was the topography around Quezi Mountain.

Is it to sketch a map?

Zhen Guogong shook his head, he not only has such a map, but also has more than one, if this is the case, there is no need for Han Yan to spend more time.

Sure enough, I saw that Han Yan did not stop writing, but drew another thinner Jianxiao, and continued to sketch out those mountains, water flows, and roads, and soon the details such as how high the mountain was, whether the mountain was steep, how wide the water was, and how fast the water flow was were depicted one by one, and even how the road was, the distance of the village, and so on, were carefully marked with a pen.

Afraid that Zhen Guogong would not understand, all the Arabic numerals Han Yan used words instead for the time being.

Zhen Guogong was amazed again and again, and couldn't help but high-five: "The Bird Mountain is hundreds of miles in circumference, all in my eyes!" ”

Fighting with such a map is much more useful than the ones hanging in his tent.

Han Yan smiled silently, and continued to pick up the pen and note the symbols in the picture one by one in the sitting corner of the paper.

Zhen Guogong's eyes were dark, and he quietly dismissed the people in the retreating tent, and motioned for Wei Feng to guard the door.

After a while, Han Yan put down his pen and finished work, lifted the drawings and dried them gently, and then handed them over to Zhen Guogong for careful inspection.

"It's so delicate!" Zhen Guogong held the drawings, his eyes shining, "This kind of map is much more useful than the ones hanging on the tent wall." ”

And if you keep these marks under these in mind and don't indicate them on the map, even if the map is not stolen, it will not have much impact for a while.

"How did the junior brother come up with this?" Zhen Guogong smiled excitedly and asked, "Was it taught by the master?" ”

Han Yan shook his head and said with a smile: "These are all things that Shu Yu figured out by himself. ”

As for his revision of the polishing according to the facts, it's not that he shouldn't tell Zhen Guogong, so as not to share Shu Yu's credit.

"My brother and sister are amazing! Extraordinary! Zhen Guogong sighed, "It's really a big luck for your kid to pick up a treasure!" ”

Although this map still needs to be improved from the point of view of marching and fighting, it is very rare to be able to draw it in such detail.

"True, true!" Han Yan laughed, feeling very honored.

The appearance of a proud idiot, Zhen Guogong couldn't help but want to beat him.

"In addition to this map, there are also some methods of field surveying and mapping of the terrain, which Shu Yu also figured out by himself." Han Yan said with a smile, and explained the methods one by one, and by the way, he also taught Zhenguo Gong that the mountain hydrology can be simply marked with Arabic numerals.

When Zhenguo Gong heard this, he was surprised again and again and sighed.

"Brother and sister have any other wonderful ideas, you might as well talk about them at once." Zhen Guogong looked expectant.

Han Yan said proudly: "Shu Yu has a lot of whimsy...... However, there is one more item that applies to the army at the moment, and that is the sand table. ”

"I have the sand table too!" Zhen Guogong blurted out, but after thinking about the comparison between the map hanging in his account and the one in front of him, he didn't know how rough it was, so he immediately changed his words again, "But my brother and sister's sand table must be much better than my here!" ”

After that, he pulled Han Yan to the sand table and asked him for guidance.

Han Yan clasped his hands and smiled: "It's actually not accurate to say that it is a sand table. This is still the idea that came from the beginning of the year's heavy snowfall, when she and Xiao Wangzhi were playing in the courtyard with snow, and I watched it from the sidelines. ”

After that, he put the new sand table that he had been thinking about for a long time in his heart one by one.

Zhen Guogong knew that Han Yan had outstanding military talent, and the two were from the same school, so they had the intention to learn from him, so they simply set up a position and fought against him in the art of war.

The two of you come and go, and they don't give in to each other.

It wasn't until the sun was slanting to the west that they stopped.

Even though Han Yan is extremely talented, he lacks experience in battlefield battles, and how can he compare to the battle-hardened veteran Zhen Guogong, who is ultimately defeated.

Rao is like this, which also makes Zhenguo Gong surprised again and again.

"With the martial arts and wisdom of the junior brother, if you are willing to stay in the army to serve, over time, you will definitely be dazzling, far better than the foolish brother." Zhenguo Gong Xu exclaimed.

Han Yan said with a smile: "Senior brother forgot, I still have a class of students waiting for me to go back to teach!" ”

I took the opportunity to resign.

Zhen Guogong thought that Han Yan had been in the army for almost a month, and the internal and external injuries had already been recuperated, and it was okay to go home on this matter, so it was approved.

"In the end, he is a person with a family, so I want to hope for it!" Zhen Guogong said with a smile.

I heard Han Yan and Shu Yu talk a lot, although he had never seen Xiao Wangzhi's face, he felt very familiar with this nephew in his heart, and he also liked it.

Thinking of this, Zhen Guogong couldn't help but admire Shu Yu very much.

It is not uncommon in this world to have a stepmother who is not poisonous, but it is extremely rare to be able to be like Shu Yu, who truly loves and cares about her stepson and raises her with her heart.

Han Yan is so blessed!

Han Yan was silent and said with a smile: "Yes." ”

After a pause, he looked up again and smiled: "When I have a chance next time, I will bring Xiao Wangzhi to meet your uncle." ”

Zhen Guogong laughed and said continuously: "Okay, good! ”

He has been stationed on the frontier for many years, and even his sons and nephews who have served in the army have not seen each other for many years, let alone children who are far away in the capital.

It's not that I don't want to, it is precisely because I miss them too much that I want to be stationed in the north all the year round to deter Warat, first, to protect the children and nephews who serve in the army, and secondly, to support the peace of the wife and children living in the capital.

Thinking of this, Zhen Guogong couldn't help but sigh.

Han Yan raised his hand and patted Zhen Guogong's shoulder, silently comforting.

Zhen Guogong turned his head and smiled, dissipated the sorrow in his heart, and said, "It's too late today, you can go back tomorrow." Tonight, let's have another drink. ”

Han Yan waved his hand again and again, and said with a smile: "Don't dare." If this continues, Master Wei will have to trouble me. ”

After knowing the relationship between Zhen Guogong and his senior brother, Wei Feng was a little closer to his admiration, and as for the embarrassment of making temptations because Wang Jigao asked him earlier, it was long gone.

Zhen Guogong laughed when he heard this.
