On both sides of the Baigou River, the vast water mist rises.

In this early spring, the surface of the river was frozen solidly, and there were no spies on either side that did not know how many spies had been sprinkled.

Yang Lin's dedication to intelligence made Tong Guan quite admirable, after all, he was born as a literati, and he was meticulous in doing things.

In this area of the Baigou River, I don't know how many spies there are in the Banzai Battalion, and the location of these people, Yang Lin also told Tong Guan generously, so as not to be injured by mistake.

Tong Guan was agitated, rode on horseback, and did not know his whereabouts, and had already been informed of the Liao people.

The Liao army will be divided into three parts: the escort army, the vanguard army and the distant exploration of the horses, and each will be led by a general.

Among them, dozens to 10,000 people were selected to form an expeditionary reconnaissance force to penetrate deep into the enemy area and listen to the enemy's reality to ensure the smooth advance of the army.

The area around the Baigou River is a continuous hill, it is very easy to hide his whereabouts, Tong Guan does not doubt it, this kind of terrain is said to be an ambush in advance, it is impossible at all.

Hundreds of horsemen escorted Tong Guan, passing through here in a mighty way, and suddenly a piercing scream came from a distance.

Everyone hurriedly stopped their horses, and when they looked at it from a distance, it turned out to be a majestic white eagle piercing into the air.

A young general's face froze, and he stepped forward and said: "Father, for no reason here, how can there be a white eagle soaring into the sky, it's not a good omen." What's more, Yang Lin is so treacherous, it's better not to go. ”

Tong Guan twisted his beard and said with a smile: "A certain take Youyan is a God-given opportunity, how can you look forward and backward."

Although Yang Lin is treacherous, he is arrogant and domineering in the court, and he deceives his superiors and subordinates, but he only relies on His Majesty's favor. So he dared to harm others, but he didn't dare to harm a certain Tong Guan, hey, this kid just entered Bianliang, or he was introduced to the official family to know his name. ”

After listening to this, everyone made up their minds a little, and Tong Guan gave an order, and everyone continued to march forward.

The official road leading to the Baigou River winds through the hills, hidden out of sight. The shadows of the trees on the mountain are longing and dense. The Song and Liao confrontations for more than 100 years, on the Hebei front, except for a few roads, trees could not be cut down in other places, and the rivers were allowed to flood, just to prevent the Liao cavalry from galloping.

This is the nearest path to Hejian Mansion, which was opened up by someone after Yang Lin arrived.

A road was cut out by Yang Lin along the east side of the river, but it had just begun, and on the towering trees around it that had not yet been cut down, at this time, there were countless lurkers who were lurking from afar.

Armed with bows and arrows, they kept an eye on the not very wide path, and just last night they touched it, waiting for an opportunity to move.

Although I don't know how the generals above knew that someone was passing by today, but obeying orders is the characteristic of probing and blocking horses, and these scouts are about to risk their lives to come behind enemy lines at every turn, and no one will ever get to the bottom of the orders they receive.

There are also many people who carry black gun barrels in trees, similar to the bazookas of later generations.

The Great Song Dynasty attached great importance to firearms, and when the Northern Song Dynasty was just established, the authorities set up "gunpowder work", and Kaifeng Prefecture was an important firearms manufacturing town. For example, all military towns, such as Jiankang Mansion on Jiangnan East Road, Jiangling Mansion on Jinghu North Road, etc., have such production workshops. According to the record of "Song Hui Yao Food and Goods", in order to produce gunpowder, during the Song Dynasty, the authorities once "recruited merchants to make 500,000 catties of sulfur in Japan", "every 100,000 catties are one gang", and escorted them from Mingzhou to Kaifeng Mansion.

This output in ancient times can be described as quite amazing, dozens of times more than the Manchu Qing Dynasty 600 years later.

The gunpowder weapons of the Song Dynasty can be roughly divided into three categories: incendiary, explosive and tubular firearms. The first two types of these are combined with projectile bows or catapults, which can be used to throw them out or directly burn or explode against the enemy. Tubular firearms, on the other hand, are closer to modern firearms.

During the reign of Emperor Shenzong of the Song Dynasty, in order to defend Xizhou and Hezhou, the Song Dynasty sent a large number of firearms, including 100,000 Shenjian rockets, 20,000 gunpowder bows and arrows, and 2,000 gunpowder artillery arrows, accounting for more than 10% of all bows and crossbows.

Although the Great Song Dynasty tried to prevent firearms from falling into the hands of the confrontational northern minority regimes, and successively adopted the methods of technological blockade and monopoly of raw materials: sulfur and flame nitrate, it was still impossible to avoid the Khitan, Western Xia, Jin and Mongol successively mastering firearms technology.

Da Liao also stole the Song people's "Fireball Gunpowder Formula", "Tribulus Fireball Gunpowder Formula" and "Poison Smoke Ball Gunpowder Formula" of the Song people early.

After the explosion of the "poison smoke ball", the poison in the ball smokes and acts like a poison gas bomb; The "Tribulus Fireball" uses the powerful thrust of the explosion to release the thistle in the ball to kill and injure the enemy; As for the "Artillery Powder Law", it mainly has an incendiary effect after explosion.

And coincidentally, the entire Khitan firearms production was completed in Yanjing.

These gunpowders and firearms naturally belonged to Yeluchun.

There was a rapid sound of horses' hooves, and the Khitan guards in the trees became nervous, waiting for the prey to approach this ambush place.

They didn't care about the men and horses in front of them, just staring at the team, searching for their prey.

Finally, Tong Guan, who was surrounded by a group of people, came over, his clothes were a little more eye-catching, these Yandi Khitan people were far away, and they were very familiar with the generals' costumes of the Great Song Dynasty, and Tong Guan was wearing the robes given by the emperor, which was even more noble.

When they got closer, the arrow wipers fell. Tong Guan and his own soldiers could only hear the sound of a bowstring trembling, and the feather arrows swished, beckoning towards their own people.

Toxic smoke fills the air, fires erupt, and heat waves scorch. Shooting at such a close range maximizes the power of firearms, and the main role is to disturb the war horse.

Dozens of fire pipes have fallen from the trees to the ground, the fireworks are still shooting indiscriminately, sparks are splashing, the war horses are alarmed, the neighing sound is continuous, everyone has drawn out their blades, and the sound of breaking the air is still chaotic, Tong Guan was shocked, there are already seven or eight feather arrows, already shooting straight towards his face with a strong wind!

"Protect your father!"

He would never have thought that he would be ambushed here, surrounded by scouts sent by Yang Lin, so many people were in ambush, how could they not be aware?

It's Yang Wenyuan's thief who wants to kill someone! This is the last thought of a generation of eunuchs when they are dying, and in a flash of light, he suddenly thought of five years ago... Yangzhou Mansion, leaning on the red and green, drunk and golden. The three of them talked about their life aspirations, cited them as confidants, and made friends who forgot about the year.

The sharp arrow passed through Tong Guan's body, and the huge force shot him off the horse, bleeding profusely, and he was obviously dead and could not die again.

The pro-soldiers of the Shengjie army looked like crazy demons, in a hurry, they couldn't even reach the enemy on the tree, everyone saw that Tong Guan was dead, and the enemy was out of their reach, these pro-soldiers of the Shengjie army, red eyes, got off the horse to protect Tong Guan's body, and wanted to drag him out.

Yuan Zhuzi didn't dare to be sure if Tong Guan was dead, so he put others aside and shot these guards and Tong Guan they were protecting.

These young guards, regardless of the rain of arrows, desperately rushed to Tong Guan's body, protecting Tong Guan's body with their bodies.

One after the other, like moths to a fire, without hesitation.

The Khitans in the trees were moved, their figure was to shoot the leader of the general, as for the others, it didn't matter.

The rain of arrows stopped, allowing the guards to escort Tong Guan's body out, and a white eagle hovered over the dense forest.

A day later, Hejian Mansion was full of Sumi.

Several young generals of the Shengjie Army helped Tong Guan's coffin into the city, and Yang Lin waited at the door.

"Brother Tong Guan!"

The snorting voice frightened everyone sideways, only to see Yang Shaozai carrying his robe, tears flowing, and rushed forward.
