Hearing the return from Guizhou, Yang Yi sent Yu Xing to lead the fourth general of Gyeonggi with 1,000 men and horses for the sake of insurance. Although the fourth general of Gyeonggi was armed with flintlock pistols, he was an infantryman, and in order to gain time, Yang Yi had to choose Liu Wu's 5,000 cavalry to help.

At the same time, in order to divert Ruan Zhishun's attention, lest he stare at Guizhou, Yang Yi led Guangxi's fifth general, Lan Jilong, 4,000 men and Bao Yi to Kunlun Pass.

Kunlun Pass and Penn and Yongzhou, dozens of miles away from Pennsylvania, Yang Yi led the army to arrive in half a day.

The mountain near Kunlun Pass is not very high, only dozens of zhang, but the peaks are sandwiched, the dense forest covers the sun, and there is a unique sheep intestine trail winding in the mountains. The mountain is half earth and half stone, which is easy to build fortifications.

When Yang Yi led the army to arrive, he saw flags flying on the mountain, and there were many people, and he couldn't see how many people there were for a while.

The Vietnamese army has dug a trench, built a rolling stone and a log, and is ready for battle, and even the trail is blocked with huge stones.

If you want to attack the mountain, the terrain below the mountain is narrow, and the army can't move, so there is really only "going forward and succeeding".

Sure enough, it's a one-man pass, and it's not open!

Bao Yi looked at such terrain, frowned and said: "My lord, it is definitely not possible to forcibly attack the mountain, and my subordinates think that the only feasible way is to lure the enemy down the mountain and fight again." ”

Yang Yi said: "As soon as Ruan Zhishun heard that our army had arrived, he immediately withdrew from Liuzhou and retreated to Kunlun Pass, obviously intending to consume our army and lure him out of the pass, I'm afraid it won't be easy!" By the way, General Lan is stationed in Quang Nam and is familiar with the situation here, what can you do to win this level? ”

Lan Jilong immediately shook his head and replied: "Back to Chief Yang, if you can't lure the enemy down at such a dangerous pass, the general really can't think of any tricks, I'm afraid there is only one way to attack." ”

"There's no need to storm it, let's try a feint, let's clean up a few hairy monkeys first." After Yang Yi finished speaking, he immediately began to arrange.

Li Tong, the deputy general of the Vietnamese army, was secretly happy when he saw that the Song army finally appeared in front of Kunlun Pass. Guizhou is in full swing, there has been no movement here, he has worked hard to build a large number of fortifications on the mountain, tired and half dead, and has to endure mosquito bites, if the Song army does not come, will not waste his strength in vain?

Li Tong believed that with the painstaking construction of the fortifications, even if 100,000 Song troops came, they could be buried in Kunlun Pass.

A big banner with the word Yang at the foot of the mountain waved in the wind, which made Li Tong's eyes shine, and before he could think about it, there was a rumbling war drum under the mountain, and he saw the dense Song army discharging the mountain attack formation, the shield in front and the bow in the back...... Li Tong looked at it and smiled, the shield was a fart, and the boulder was rolling down, no matter how many shields there were, it would be useless.

He looked back at the Vietnamese army waiting in the trench, and said with a rude smile: "Brothers, the Song army has come from afar, and they don't know the battle formation, and they want to attack such a dangerous pass with thousands of men and horses, everyone is ready for me, and when the Song army rushes closer, smash me hard, smash him on the head and blood, and open the flesh, anyway, there is no shortage of stones on our mountain, hahaha!" ”

Li Tong looked up to the sky and laughed, and the defenders on the mountain also followed suit, shouting insults, and the mood was extremely relaxed, indeed, occupying such a dangerous pass, what is the difference between cleaning up thousands of Song troops and cleaning up thousands of ants? There's really nothing to worry about.

The main general Li Yongtai saw Li Tong's performance and frowned secretly, although he didn't think that the Song army could attack the mountain with a few thousand men, but after Ruan Zhishun turned over the preaching, he would no longer despise Yang Yi.

Nguyen Zhishun had attacked Quang Nam with Li Changjie 20 years ago, he was bold and careful, made great achievements, and was taught by Li Changjie the battle formation strategy, as Li Changjie gradually grew old, Ruan Zhishun has become one of the top generals in the country of Da Viet.

A few years ago, Nguyen Chi Shun defeated the 40,000 enemies of Chenla with 3,000 people, which greatly boosted the prestige of the Da Viet Kingdom, and then in a series of wars against Chenla and Champa, Nguyen Zhishun attacked and won, and seized a lot of territory and population from Chenla and Champa.

Including Li Yongtai, almost no one in Da Yue does not respect Ruan Zhishun, it can be said that Ruan Zhi Shun is like a god of war in Da Viet country, but now, as soon as he meets Yang Yi, Ruan Zhi Shun is actually cautious step by step, and before he engaged, he immediately retreated hundreds of miles, took a defensive position according to the danger, and copied Yang Yi's troop habits and strategic intentions day and night.

How can someone who can make Ruan Zhishun walk on thin ice and be cautious every step of the way?

Li Yongtai was full of thoughts, the war drums under the mountain rumbled for a while, and hundreds of Song troops, under the leadership of Lan Jilong, brandished knives and guns, howled loudly and rushed towards the mountain.

The arrow was about to stand up, and at this moment, the sound of "Bah!" sounded from the bottom of the mountain. Bang! Bang! A burst of gunpowder smoke rose and bullets whistled, and the Vietnamese soldiers who were shot on the mountain burst out a puff of blood and fell to the sky.

There is a gap between the Li Dynasty and the Great Song Dynasty, always paying attention to the changes of the Great Song Dynasty, the flintlock pistol has heard of it, but no one has ever seen its power, until now, the Yue army on the mountain is terrified, the distance of the Song army's shooting, I am afraid that only the bed can reach so far, the bow and arrow can not shoot at all.

Surprised, many Vietnamese soldiers forgot to retreat into the trenches to hide. Of course, this is also because of the long distance, the Vietnamese army only has the trench above the shoulder, and the Song army's flintlock pistol is not effective, and it has not been able to cause a large number of casualties to the Vietnamese army, and it cannot achieve much deterrent effect.

However, Yang Yi changed the gun after shooting, and several guards behind him helped to load the ammunition, and the sound of gunfire continued to sound, even if the accuracy of the flintlock pistol could not be compared with the blocking rifles of later generations, he could kill at least two of his three shots.

Sergeant Song was envious and admired, and couldn't help but cheer loudly, and the cheers were louder than Lan Jilong's shouts of their charge.

"Yang Dashuai is invincible!"

"Yang Dashuai is invincible!"

"Yang Dashuai is invincible!"

…….

Yang Yi couldn't cry or laugh, I still can't fall with a golden gun! Is there such a boast? It feels like a bunch of pig brothers watching someone prostitute and keep cheering that person on.......

At this time, Lan Jilong, who was charging, led people to turn around and run, and after running out of the range of the Vietnamese army's bow and arrow, he immediately turned back to the Vietnamese army on the mountain and kept insulting and mocking, but the Vietnamese army was not stupid, who would stand and scold them, and retracted into the trench one by one, so only the scolding was heard on the mountain, and no one was seen, which made the Song army cry out helplessly.

Lan Jilong and they came to a feint again, the Vietnamese army ate a trench and grew wise, this time they didn't show their heads at all, Lan Jilong They didn't dare to really attack, otherwise the boulders of the Vietnamese army rolled down, it was not to lure the enemy, but to send them to death!

Bao Yi sighed: "My lord, it would be nice if we brought a few artillery." ”

The artillery of the Great Song Dynasty has always been only "researched" not "made", except for the Tokyo city of Tokyo, which has not been equipped with an army, Bao Yi They only heard that the artillery is powerful, but they don't know much about the actual performance of the artillery, so they have this sigh, thinking that pulling a few artillery pieces can solve the problem.

Yang Yi shook his head and said: "It is difficult to march empty-handed in the land of Guangnan, the artillery is bulky and difficult to carry, and the enemy has dug trenches in the mountains, and a few artillery pieces will not have much effect. ”

Today's artillery mainly fires solid and scattered bullets, unlike the powerful grenades of later generations, which can plow the mountain.

Now as long as the enemy hides in the trenches, the artillery is basically inlethal.

Yang Yi tried several methods, but failed to attract the Vietnamese army, so he had to order the retreat of the troops to camp for ten miles.

Bao Yi said a little unwillingly: "My lord, forget it?" ”

Yang Yi shook his head and replied: "The so-called war, fighting is nothing more than the time, location, and people, and now the enemy has taken advantage of the location, if we meet hard, the gains outweigh the losses, so we can only think of ways from the other two aspects, Bao Yi, if you can't figure out this truth, you will never be able to become a commander alone." ”

Bao Yi thought for a while and said: "Thank you for your teachings, my subordinates now understand a little, my lord led the army to the south, the mountains in the south are dense and forested, and the roads are difficult to travel. The adults had long expected this, so before the expedition, they asked the imperial court to send envoys to Dali, Zhenla, and Zhancheng. As soon as he arrived in Guizhou, he immediately ordered people from 44 prefectures, 5 counties, and 11 dongtou to rush to Pennzhou. The adults do this to seize the people, and once this person is grabbed, the Great Song Dynasty, Dali, Zhenla, and Zhancheng are surrounded on all sides, and the geographical advantages of Jiaozhi will be offset. ”

Yang Yi nodded and said: "Yes, Bao Yi, you remember that when formulating a strategic plan, the first thing to consider is the three elements of time, location, and people. When the enemy has the right time, we will create the right place, and when the enemy has the right time and place, we will create the people. If the enemy occupies all three elements, he cannot fight, and he will lose the battle. We can only find a way to destroy the other party's time, place and people, such as Dali, Zhenla, Zhancheng and Jiaozhi are in collusion to resist the Great Song Dynasty, we need to win over one or two of them first, or even all of them, and destroy their people and destroy them, and the way of destruction can be political, military, economic and even anti-traitor and other different means. This is a big strategic aspect, as small as every tactical use, all these three elements can be applied, such as the current Kunlun Pass, the enemy occupies the dangerous pass, and the people are not inferior to us, we can only seize the time, only have a game. ”

Bao Yi is a general who grew up from the lower level, and he has not been a senior general for a long time, there are relatively few books in these years, and the experience of the battle formation is often passed from father to son, and from son to grandson.

The appearance of "Jiangmen" is not really because only this family has military talent, but because the children and grandchildren have gained combat experience from their parents that is difficult for ordinary people to get, so that they grow up faster than ordinary people.

In his previous life, Yang Yi was originally from the military. I have seen countless analyses of ancient and modern war examples, and it can be said that he does not lack theoretical knowledge, and the key is to see whether he can use them flexibly.

Bao Yi and them are different, what they lack most is the knowledge of these military theories, these things sound simple, but in the era of backward information, they are by no means available to ordinary people at will.

Therefore, Bao Yi remembered every sentence of Yang Yi attentively, and he was very grateful in his heart, and finally he said cautiously: "Do you want to come back at night to occupy the sky?" ”

"Hahaha, the son can be taught!"
