Although Tolei was beaten to only about forty people, he was not discouraged when he saw Bolu. Instead, he was thinking about how to crack the tactics of Tongzhou firearms day and night.

In him, Bolu saw Mu Huali and Da Khan in his youth.

This kind of fierce and bravery and unyielding spirit has disappeared from the increasingly arrogant Mengjun for a long time, but now it has appeared on the fourth prince again.

Therefore, Bolu was also very worried and formed an alliance with Tolei.

In fact, at that time, the Grand Tutor King Bolu was also in an extremely embarrassing moment.

The old place of Jin Kingdom handed over to him by Dahan was his father Mu Huali and Dahan fought bloody battles. How many grassland warriors had lost their money, but now they were almost half in his hands! So at this time, Bolu, who was also in a frustrated state, hit it off.

The two of them agreed that Bolu would send troops to avenge him.

Tolei tried his best to win the support of the Khan for Bolu on firearms in the rear.

In addition, Bolu also learned from Tolei's defeat, so Bolu was full of confidence in this battle.

What's more, the fourth prince Tuolei sent him a strategist like Li Lijue who was familiar with the situation of the Tongzhou army... When he thought of this, Bolu turned his attention to Li Zhuojue.

At this time, Li Zhuojue certainly understood that as soon as he saw Tuolei, he turned to the fourth prince, and now he is a member of Tuolei's lineage.

In this battle, he had to play a role, so that Marshal Bolu and even the Fourth Prince Tolei above looked at him with admiration! So Li Zhuojue raised his eyes to the mountain, and looked at the Tongzhou mountain infantry, whose guns were constantly coming out, and then said to Bolu: "Based on my previous experience, even the most powerful soldiers in the Tongzhou army could find it difficult for their rifles to shoot targets more than a mile away.

Because once you pass this distance, the rifle will not be able to hit it accurately.”

"But the artillery we brought this time has a firing distance of just over one mile!"

"good!"

Hearing Li Zhuojue's words, Bolu's eyes immediately lit up, and then he burst into tears.

If you say that Bolu is also a person who is proficient in military tactics, the so-called drums do not require heavy hammers.

As soon as he heard Li Zhuojue say the beginning, he immediately understood what he meant.

Bolu thought to himself: Unexpectedly, Li Zhuojue is really a talent! He actually revealed the way to deal with mountain infantry in one go, that is, to use the range advantage of artillery and set up guns wherever there is an enemy! At this time, Bolu looked at Li Zhuojue with appreciation, and then arranged the tactics... Not long after, the roar of the rumbling Mongolian iron cannons came from the mountains.

...So it would be fine to say that Li Zhuojue knew some of the inside story of the Western Xia, but he really knew that Tongzhou army so well?

It's true.

Because Li Zhuojue was once defeated by Wu Chaoyang, the Tongzhou Army, after that, he led Shen Mo as a great enemy in his life, so he has always paid great attention to collecting information from the Tongzhou Army.

But in this world, there was an army that had been in close contact with the Tongzhou army on the battlefield in Xixia... It was the 40,000 Xixia Iron Harrier. He once fought side by side with the Tongzhou army in the Yangtze River barrier! With Li Zhuojue's careful collection, information about the military system and weapon performance of the Tongzhou army was growing in Li Zhuojue's hands... Now after Li Zhuojue defected, this information became the capital he used to please his new master!... After the Mongolian army fired, the mountain infantry immediately became less relaxed and pleasant as before.

Previously, they could use the range advantage of their rifles and mountain terrain to attack the enemy as they please.

Anyway, when the enemy rushed up, he had already run away.

But if they do this again this time, the enemy will not have to come up to chase them.

As long as the Mongolian army set up shells from a distance, it would pose a threat to the mountainside position.

These iron cannons often splashed with gravel and a steep mountain immediately rolled around.

Moreover, when the shells directly kill the mountainside position, it will also cause damage to the infantry inside.

Therefore, the mountain infantry decisively gave up position defense. According to the commander's previous requirements, their combat operations should be based on protecting their own soldiers.

So in order to avoid casualties, they began to take the initiative to evacuate backwards.

Because of the news from behind, Gubeikou was ready to fight the Mongolian army. They delayed the enemy's mission and have been successfully completed now.

The evacuation of the mountain infantry even led to the speed of the Mongolian army's advancement.

They finally arrived at Gubeikou City Pass before sunset.

This time, the number of iron artillery equipped in the Mongolian army was several times that of the previous Tolei army, and it had reached 600. Moreover, they also brought a large number of Mongolian versions of 10,000 enemies.

So when the war was about to begin, Marshal Bolu came with a heart of revenge and avenged his shame, and he was full of confidence in his victory!... At the same time, not all the Mongolian troops under Bolu were rushed to Gubeikou.

They did not divide the troops into two groups as Shen Mo expected, but into three groups! One of them was Bolu himself with 600 cannons and 70,000 Mongolian troops attacked Gubeikou.

The Second Route Army was led by the former Yu Pass guard Kuokuobuhua, and the direction of the attack was Dushikou, the northernmost end of Yanshan.

The reason why he was allowed to lead the army was because Kuokuobuhua was originally a general under Bolu, and he was also one of the few generals who could still survive after fighting with the Tongzhou army.

This time, he led 30,000 Mongolian cavalry and 100 cannons to attack Dushi Pass, approaching the place where Yang Qingyue defended.

The number of soldiers in the third route was 20,000, led by the former Feihukou Guard General Chilietai.

This time, Bolu sent Cyretai because of the report he reported after returning to Huanzhou.

At that time, Qinlietai said that the number of soldiers in Tongzhou that captured Feihukou was very small, with less than a thousand people.

But because they fell from the sky and caught the troops in Xiaoling Ancheng Pass off the guard, they occupied the natural danger.

This Qinlietai stationed in Feihukou for several years and is very familiar with the terrain and the city gate there.

What's more, the number of defenders in Feihu's mouth is pitiful, so Feihu's mouth is regarded as the third breakthrough by Bolu.

He sent Cyretai and 20,000 troops to attack Feihukou, and also brought twenty artillery pieces... By the way, the terrain of Feihukou was narrow and even if there were too many artillery pieces, they could not be displaced.

As Bolu thought, with the powerful siege such as artillery this time, I believe that the Cyretai is very likely to retake Feihu's mouth.
Chapter completed!
