Hearing Lu Xiaoxian's words, Chai Liu and Chen Xuanli's faces turned red. Although they have more experience in the military than Lu Xiaoxian, they do not consider the problem as comprehensively as Lu Xiaoxian.

Lu Xiaoxian was ashamed to ask, Chen Xuanli naturally couldn't hide his secrets, he said with a bitter face: "The mobility and attack power of the cavalry are impossible for the infantry to resist, and the infantry has almost no chance of winning when encountering the cavalry, especially in the field, the advantage of the cavalry is even more obvious." ”

"So, if we encounter the Tibetan cavalry, there is only one way to die?" Listening to Chen Xuanli's words, sweat broke out on Lu Xiaoxian's forehead.

"Not necessarily!" Chen Xuanli pondered for a moment and said, "As long as the response is appropriate, although it is difficult to win, self-protection can still be done." ”

"I didn't even think of winning, as long as I could protect myself!" Lu Xiaoxian wiped the sweat from his head and urged, "Tell me how to deal with it!" ”

"To deal with cavalry, you must lay out a suitable formation!"

"Formation?" Lu Xiaoxian's mind flashed the gossip array in the film and television dramas of later generations, do you have to set up a gossip array to deal with the cavalry?

Chen Xuanli continued: "There are many carts that escort baggage, and it is most suitable to use a circular array!" ”

Oh! It's a circle array, not a gossip array! Wait, what is a circle?

Lu Xiaoxian felt that his mind was twitching, and he regretted it a little, why didn't he ask Xue Huaili to help him copy some books on the art of war when he came, he really hated it when the book was used!

Seeing Lu Xiaoxian's blank face, Chen Xuanli patiently explained: "Among the eight formations in the Book of War, the square formation, the circle formation, the peony formation, the smug formation, the rushing formation, the wheel formation, the floating frustration formation and the goose marching formation, these formations have their own strengths and weaknesses. The circle is to enclose the spearmen in a circle, with the muzzle facing outward, to prevent the cavalry from charging into formation, and the archers shoot the enemy after the spearmen! In that year, the Han general Li Guang led 4,000 cavalry to fight with the 40,000 cavalry of the Xiongnu, which made the circle resist for two days, and finally supported until the rescue arrived! ”

Lu Xiaoxian probably understood, and hurriedly nodded: "Hmm! Yes, yes, it looks like we're going to have to hurry up and train this round formation! Captain Chen, this formation is going to rely on you! ”

Guo Zhen shook his head on the side and said: "This method is good, but unfortunately it can't be used!" ”

As soon as Lu Xiaoxian heard this, his heart that had just been put down rose to his throat again, and he asked anxiously: "Master Guo, why can't you use it?" ”

"The Tibetan cavalry has always been known for their speed, since they are attacking, how can they give you time to set up your formation?"

Lu Xiaoxian was dumbfounded when he heard this, Guo Zhen was right, would the Tubo people wait for you to set up a formation before attacking?

He looked at Chen Xuanli, Chen Xuanli smiled bitterly, obviously he had made this mistake, and there was no good way to solve it.

Lu Xiaoxian pondered for a moment and asked Chen Xuanli, "How long do you estimate it will take for this round array to be set up at the earliest?" ”

"At least half an hour!" Chen Xuanli replied.

"Half an hour! Half an hour! Lu Xiaoxian's mouth was muttering, his head was not idle, and his brows were twisted into pimples.

After a long time, Lu Xiaoxian said to Chen Xuanli: "Captain Chen, you just have to train and set up the formation for everyone, and I will find a way to do it in this half an hour!" ”

Chen Xuanli looked at Lu Xiaoxian strangely: "Master Lu, what can you do?" ”

"I'm thinking of a stupid solution!" Lu Xiaoxian smiled bitterly: "When the convoy was marching, scouts were dispatched, and after discovering the Tubo cavalry, they quickly warned them!" The convoy sent 200 people to block the Tibetan cavalry, buying half an hour for the formation! ”

Chen Xuanli exclaimed: "Gecko tail broken? ”

Lu Xiaoxian nodded.

Guo Zhen reminded: "These 200 people will not come back!" ”

Lu Xiaoxian asked rhetorically: "Then do you have a better way?" ”

Guo Zhen stopped talking.

"Okay, that's it, Captain Chen, you hurry up and train the formation......"

"Wait!" Guo Zhen interrupted Lu Xiaoxian's words, "I have also heard a little about this round formation, and the spearmen must be extremely powerful, otherwise they will not be able to resist the war horses rushing at high speed." ”

Speaking of this, Guo Zhen showed a helpless expression on his face: "These united soldiers recruited by Guangwu County are probably not qualified for the role of spearmen!" Also, the archers have to shoot their enemies with arrows all the time, and they can't do that! ”

Lu Xiaoxian closed his eyes in pain.

Two hundred lives were exchanged for half an hour, and if Bu's circle could not play a role, wouldn't these two hundred people die in vain?

Lu Xiaoxian kept pulling his hair, he had to come up with a way as soon as possible, otherwise he would really run into the Tubo people, it would be a one-sided massacre, and he would never allow such a thing to happen.

After thinking for a while, Lu Xiaoxian asked Chen Xuanli: "The advantage of the Tubo cavalry is that it is fast, is there a way to slow down the speed of the cavalry?" ”

Chai Liu, who had not spoken, said on the side: "Master Lu, I have a way, I don't know if it's feasible?" ”

Lu Xiaoxian's eyes lit up, and he said to Chai Liu: "What method?" Tell me about it? ”

"We used to use thistle terrestris against cavalry, and this is an inconspicuous but effective one, it has four iron spikes, and if you throw it on the ground, one of the thorns will always face upward. As soon as the horse stepped on the thistle, it would cause confusion, and the speed would naturally decrease. In addition, you can also dig some horse traps, only need to circle three inches and half a foot deep, as long as the horse's hooves step into the pit, the horse's legs will definitely be broken. ”

After listening to Chai Liu's words, Lu Xiaoxian almost didn't hug his face and kiss him, he was so talented, he could come up with such an economical and practical method, he really deserved to be a veteran on the battlefield.

"Good, good! Uncle Chai, your method is good, I'll go to the blacksmith shop to get thistle! Lu Xiaoxian was overjoyed.

Chen Xuanli was also inspired by Chai Liu's words, he patted his head and said, "As for the spearmen, I also thought of a way, which can be replaced by rejecting horses!" The law of war of the guards says, the rejection of the horse pistol with a wooden diameter of two feet, the length of the matter, the cross chiseled holes, the vertical and horizontal security checks, the length of one zhang, the sharp end, can be plugged on the road, people and horses are not allowed to gallop. ”

This Lu Xiaoxian knew that it was an obstacle that inserted multiple spears into the log to block the charge of the enemy cavalry. In this way, the problem of the spearman was solved, and now only the problem of the archer killing the enemy remained.

"If we are ten or twenty years younger, archery with a bow is nothing at all, but now that we are old and have no strength, I am afraid that archery will be impossible!" Chai Liu had the strength to not admit defeat, he held his head high and said, "However, our Guangwu veterans are all good at throwing spears, I could have thrown spears fifty paces away, and when I landed, it was enough to penetrate two layers of cowhide shields. Now it's a little worse, but at a distance of thirty paces, it's still no problem to shoot cavalry! ”

"That's right!" Guo Zhen seemed to remember something, and he interjected, "Among the baggage we escorted, there are a lot of crossbows, and the unity soldiers can't shoot arrows, so there should be no problem with crossbows!" ”

Listening to Guo Zhen's words, Chen Xuanli showed a look of disdain on his face.
