The two of them chatted while looking at the scenery along the way, if they hadn't known that they were going to the front line to fight, it would have been very pleasant.

Hui Shangyi has walked through many places, and every time he sees a scene, he can tell Xiao Li something, and Xiao Li can listen to it with relish.

"This battle is actually very crucial, if it is successful, it can protect the peace of the border for several years." When Hui Shangyi talked about the changes in the situation in the country in recent years, he said with emotion.

Xiao Li has always been able to see how much attention everyone attaches to this battle, otherwise the enemy army would not have taken such painstaking measures, and the meticulous work found this time must have been planted in Huifu for many years, and it will not be used until the critical moment.

Thinking of this, Xiao Li secretly made up his mind that he must make some contributions to this battle.

"Is there anything tactically difficult to overcome in this battle with the enemy?" Xiao Li asked.

Hui Shangyi didn't seem to expect Xiao Li to ask this kind of question for a while, so he thought about it carefully and said, "When Xie Junshi wrote a few days ago, he mentioned that when he was fighting against the enemy, there were always some problems in defense. ”

Although the iron fan that Xiao Li researched before was indeed tried in defense, it took many exercises to be proficient in use, and only the Women's Army was equipped with it, so it has not been promoted.

"That's a real problem." Xiao Li said with a frown, silently rubbing his chin.

In the past, she had used the advanced military knowledge she had brought from modern times to solve many strategic problems, so this time, she instinctively looked for ways in the modern war materials she had seen.

Suddenly, she thought of a common method used in modern warfare - trenches.

She has seen in some military books the introduction of this means of defense, originated from foxholes, can be a good protection of the human body, when critical, can also lie down, such as explosives This kind of large-area killing weapons caused by the damage, but in modern times, it is rarely used again.

"Trenches? Isn't that kind of trench used to hold back the enemy? Hui Shangyi listened to her talk about the concept of trenches and looked at her with some puzzlement.

It is true that in ancient times there were things similar to trenches, but in ancient times, a trench was dug in the ground, waiting for the enemy to step into it, and in modern times, people themselves hid in it.

"I mean, our people, we can hide in that trench to protect our bodies, and we can also reduce some casualties." Xiao Li explained to Hui Shangyi.

However, Xiao Li didn't know if the trenches could also be used in the era of cold weapons.

Because in modern times, there are basically no swords in hand-to-hand combat, but guns are flying all over the sky, so the protective effect of trenches is very strong, although it requires preliminary preparation, but it has also been widely used.

"So, you can try it too, but how do you lay it out?" Hui Shangyi nodded, understanding what Xiao Li meant, but he didn't know how to directly apply such a defensive line.

Hui Shangyi was very curious about where Xiao Li got this knowledge, after all, it was impossible for an ordinary woman to come into contact with this, but Xiao Li was not from their time, so he wouldn't feel very strange, let alone ask too much.

He believes that everything Xiao Li does is based on the starting point that is beneficial to him, and he is very relieved.

"I'm thinking about that, too." Xiao Li fell into deep thought.

First of all, trenches may not be used as a frontal as in modern times, because both sides have to fight each other on horseback, and it is not practical to defend with trenches.

Projectile weapons such as bows and arrows and catapults should be similar to modern guns, but they are not exactly the same, for example, catapults are best used when they have a certain terrain advantage and are extremely lethal.

"It's okay, don't force yourself too much, Junshi Xie will be there in a while, you can discuss it with him." Hui Shangyi could see that Xiao Li had a headache, so he comforted him.

"My initial idea now is that the front is still to deploy cavalry to attack directly, and then dig trenches on both sides to arrange archers, and it is best to use a certain geographical advantage to form an encirclement and surround the enemy." Xiao Li expressed her thoughts at the current stage, and she could only think of these for the time being.

"I think it's good." Hui Shangyi nodded, and admired Xiao Li very much in his heart, because he knew almost nothing about tactics, and he had relied on Xie Yunxiu's help for many years, and he really couldn't think of an idea like Xiao Li himself.

"No, it's not enough, I need to measure the layout of the trenches again." Xiao Li shook his head, not happy because he was affirmed by Hui Shangyi, but thought about it more seriously.

Indeed, the location of the trench is the most important thing in the layout of the defensive line, and the greatest role of this thing is to resist frontal attacks, and it is time-consuming and laborious to arrange, and the location cannot be easily selected.

Hui Shangyi knew that Xiao Li cared about the battle on the front line, so he didn't stop it, and secretly sighed in his heart that it would be good if he could help tactically. The only Chinese network

"I don't know if Hui Shangxian's kid can manage the military camp alone, I'm afraid he will be in a hurry." Hui Shangyi didn't want Xiao Li to be too tired, so he changed the topic in time.

Xiao Li was naturally a little caught off guard by his sudden mention, and looked at him in surprise with his mouth open, thinking that he was still angry with his brothers because of the previous incident.

"He won't, I know what he's capable of, and he's very mature." Xiao Li shook his head and said with certainty.

Hui Shangyi actually knew that if Hui Shangxian didn't have the ability to lead the army, he wouldn't have thought that he and a small number of people would come back to find him and let the large army continue to move forward, but when he saw Xiao Li's serious appearance, he felt a little funny.

"You seem to know him well?" Hui Shangyi deliberately showed an unhappy expression, and said in a strange manner.

Xiao Li smiled dumbly: "I taught him martial arts at the beginning, how could I not first understand his character and ability?" ”

"It's true that he's very talented, but it's a pity." Hui Shangyi sighed softly, and knew that he knew too little about his younger brother before, and when the relationship between the two officially began to ease, many things were already late.

"You're kidding me?" Xiao Li suddenly reacted that Hui Shangyi was pretending to be jealous just now, and he was slightly angry, glaring at Hui Shangyi.

"I didn't fool you, it's the first time he's coming out." Hui Shangyi hurriedly accompanied the smiling face, for fear of making his own female general angry.

"Alas, now is not the time to joke, in fact, I'm glad that my father let Hui Shangxian come out, with him, there is also a guarantee of combat effectiveness." Xiao Li sighed softly, but there was a worried expression on his face.

"Okay, I'm not worried about the general, why are you worried? It's really the emperor who is not in a hurry......" Hui Shangyi gently patted Xiao Li's back and said with a big grin, but seeing Xiao Li's increasingly dark face, he stopped the second half of his sentence in time.

He didn't dare to say the last two words, but he was afraid that he would really become the last two words.

Alas, why is he such a temperamental mother-in-law, and he has no regrets?

Xiao Li was teased by Hui Shangyi like this, and his mood was relaxed, and he stretched his arm lightly on the horse, thinking that it was better to take one step at a time, there would always be a way, and he couldn't think of it, isn't there still Xie Yunxiu's demon.

Thinking of this, Xiao Li finally smiled at Hui Shangyi.

Hui Shangyi also breathed a sigh of relief, and the two of them returned to their previous state, talking and laughing along the way, each telling their previous stories to relieve their boredom, and soon, they saw a camp tent in front of them, prominently planting the flag of Shengguo.

"It's here!" Both of them were very happy in their hearts and smiled at each other.

"Major General! You're finally back! The deputy general saw Hui Shangyi and Xiao Li from a distance, and also greeted him happily.

This army lacks a main general, and it always seems very cohesive, so when Hui Shangyi is not there, the military spirit is always a little unstable, and the deputy general and Hui Shangxian waste a lot of strength to stabilize the situation.

And Hui Shangxian also followed behind the deputy general at this time, and nodded lightly at the two.

And when his eyes swept to Xiao Li, he saw that her face was as usual, and she looked pretty good, and he finally breathed a sigh of relief in his heart, it seemed that the medicine he left behind still had an effect.

"Major General, this is the strategic layout map this time, please take a look." Soon another soldier arrived at the drawings.

Hui Shangyi waved his hand, refused, and said, "I'll look at it later, and send the young lady back to the tent to rest first." ”

So, everyone consciously gave way to jump, and Hui Shangyi did not shy away from gently picking Xiao Li off the horse in front of many soldiers.

For a while, there were bursts of very ambiguous coaxing around, Hui Shangyi usually didn't have a fight, and everyone was very familiar with each other, so he didn't shy away from it.

"Let me down, I can do it myself." Xiao Li's face was hot, and he whispered in Hui Shangyi's ear.

"How's that going to work? Your leg isn't healed yet. Hui Shangyi glanced at her reproachfully, but he couldn't hide a smell of urgency.

After that, he ignored Xiao Li's quiet pinching of the flesh on his body with his fingernails, and walked directly towards the camp tent with a large number of people, and there was cheers behind him.
