There were checkpoints on land and on the water. As soon as their passenger ship arrived at the edge of the city, two speedboats came from the left and right.

"It's the Plum Blossom Guard!"

Li Bao shouted softly, his eyes full of worry.

Without the emperor's will, all royal families are not allowed to leave the capital without authorization, and violators will be severely punished.

The eunuchs even took advantage of this rule by using chicken feathers as arrows. In December last year, Li Yu, the king of Hanzhong County, went to Yanshi County without permission and was caught. Li Fuguo used this order from the emperor to deprive Li Yu of his royal title. , and was placed under house arrest for three years without being allowed to leave the house. Even the queen's intercession was of no use. The key is that Li Fuguo had long wanted to deal with Li Yu.

Of course Li Bao was worried. If he was caught, everything would be over.

However, Tian Shenqi was prepared. He walked out of the cabin and showed a silver medal to the leading general. This was the pass issued by Wang Siyi. No inspection was allowed, and there was no obstruction.

"Let go!"

The leading general shouted, and several intercepting ships moved out of the way. The passenger ship quickly accelerated and sailed out of the city, and soon left Luoyang City.

"Third uncle, what is that?" Princess Tian asked curiously.

Tian Shenqi waved the silver medal proudly, "This is the key to our leaving Luoyang tonight. The silver medal can pass through the water, and a single ship can not be inspected. I bought it from Wang Siyi for three hundred taels of gold."

"What if it's a gold medal?" Li Bao also asked curiously.

Tian Shenqi chuckled, "The gold medal is for Li Fuguo. With the gold medal, not to mention a passenger ship, even a fleet of cargo ships can pass through the city without being inspected. In the past, Li Fuguo used to charge money to let people go. Starting from this year, He won’t accept any money anymore, just like when you leave the city, he will never let it go!”

"Will there be an interrogation ahead?"

Tian Shenqi smiled faintly, "Of course there is an interrogation, and there are two more interrogations, but there are loopholes in it. The water and land interrogations are not synchronized. They are several miles apart. We can continue to get on and off the boat, and we can avoid the water and land interrogations. , if it doesn’t work, just use money to clear the way, this is an invincible weapon!”

Two days later, the ship slowly docked on the north bank of the Yellow River. At the agreed location, three carriages and a group of cavalry had been waiting for a long time. They got on the carriages, and under the protection of the cavalry, the three carriages sped away to the north.

At the same time, Lei Wanchun led an army of 20,000 to Feihu County. Feihu County is located within Feihu County, just in a narrow place, which cuts Feihu County in two. There are cliffs on both sides. If you want to continue eastward to Hebei, you must Capture Feihu County.

The Xiakou where Feihu County is located happens to be the junction of Yizhou and Yuzhou, as well as the junction of Hebei Road and Hedong Road.

Geographically speaking, Feihu County and the canyon behind it should belong to Yuzhou, but in fact they are controlled by the Youzhou Army.

The dangerous terrain of Feihuxing is all within the territory of Hedong Road. As long as Lei Wanchun takes Feihu County, he can directly enter Yizhou. There is no particularly dangerous place behind, only a Tiger Valley, but there is no food and supplies there, so all All food is provided by Feihu County. If Feihu County is captured, Huju Valley will lose its supply of food and grass, and it will be too late to transport food from Yi County.

Therefore, as long as Feihu County is captured, the defenders of Huju Valley will no longer defend and will retreat.

The guard general of Feihu County is called Wang Zhaoxuan, who was originally Zhu Si's personal soldier. After Zhu Si seized power, his soldiers were all given high-ranking officials and took control of the army. Wang Zhaoxuan was promoted to Yizhou Defense Envoy. He spent most of his time In Yi County, but today I happen to be in Feihu County.

There are three thousand defenders in Feihu County. The perimeter of the county is twelve miles. The city walls are made of large bluestones. They are very tall and strong. Moreover, they are located in a high place and are condescending, making it easy to defend but difficult to attack.

Wang Zhaoxuan initially thought that the opponent was Tian Shenyu's army, so he didn't take it seriously. Later, spies discovered that the opponent was flying the flag of the Guanlong Army and there were 20,000 people. He suddenly became nervous and ordered the entire army to go to the west city and defend the county seat.

His only reliance was that the county town was tall and solid, and the opponent coming from afar must not have siege weapons. Even if the opponent had 20,000 people and no siege weapons, there was nothing he could do against them.

Wang Zhaoxuan was nervous, but he was not afraid either.

The 20,000-strong army slowly stopped three miles away. Lei Wanchun slowly urged his horse out and squinted his eyes to look at the county town. He had experienced hundreds of battles and saw the weak spot of the county town, the city gate, at the first glance.

In fact, he had repeatedly discussed with Wei Feng in Yunzhong County that they could not carry large siege weapons, but they could carry small trebuchets that could throw a five-pound jar of kerosene from a hundred and fifty steps away. Go to the opponent's city.

Why do you have to use kerosene to attack the opponent first? Because the other party also has kerosene. The damn Sogdian merchant sold the kerosene of Bakhanna to Youzhou.

Why only sell to Youzhou? Because it was related to the Uighurs, and because Shi Siming formed an alliance with the Uighurs, this alliance has continued. The first thing Zhu Si did after seizing Youzhou was to send people to pay tribute to the Uighurs and submit a letter of allegiance.

So the Uighurs arranged for a group of Sogdians loyal to them to transport kerosene to Youzhou, and Youzhou had close relations with the Khitan and Xi people, which meant that the Khitan and Xi people probably also had kerosene.

Guan Long's army only had gunpowder as a weapon to attack the city gate. In order to prevent the opponent from burning the city with kerosene, there were two methods. Either strike first and burn the city head with kerosene, or use tribulus and fire thunder.

Tribulus fire thunder is an enlarged version of iron caltrops. It was widely used in the Northern Song Dynasty, mainly against cavalry.

Now the Guanlong army's caltrops and fire thunders weigh twenty kilograms and are used to deal with city gates and warships.

There are three iron nails one foot long on the tribulus fire thunder. No matter how the fire thunder rotates in the air, there will always be one nail facing the front. The sharp iron nails will definitely be able to be nailed to the city gate or wooden boat. Once it explodes, The city gates and warships will be blown to pieces. If one bomb is not enough, two bombs will be blown. If two bombs are not enough, three bombs will be blown to pieces.

Lieutenant General Yang Qing whispered: "General, if we blow up the city gate, the enemy will also pour kerosene down and use fire to prevent us from entering the city. It is better to burn the city head with fire first."

Although Lei Wanchun is a bit weak politically, he is definitely a qualified coach in terms of military.

He pondered for a moment and said, "Do you know what I'm most worried about? I'm most worried that the enemy will block the city gate with huge rocks, and we'll be in big trouble."

Yang Qing thought about it and said, "Then there's no need to hesitate!"

Lei Wanchun nodded slowly, "We must not give the opponent a chance to block the city gate with huge rocks. We must fight quickly!"

He immediately ordered: "Send the order to prepare to throw caltrops and iron thunder. Three thousand fire-fighting teams are ready! Eight thousand crossbowmen are ready! Three thousand cavalry are ready!"

Lei Wanchun passed on a series of orders.

The first to go into battle were 8,000 crossbowmen. Many of them were spear infantry, but at this moment they all transformed into crossbowmen. The 8,000 army rushed to the 200th step, set up a crossbow formation, and dense arrows were fired at the sky. City head.
