Fei County, this time Sun Xuanya learned from his lesson. He deployed 20,000 heavy troops in Fei County, vowed to guard the northern gate of Linyi County, and appointed his brother Sun Zhian as the chief general of Fei County.●⌒,.

Just when the Sui army gathered in Dong'an County in the north, Sun Xuanya also came to Fei County in person to inspect the army's preparations for war. Although Sun Xuanya had not yet obtained the situation where the Sui army was preparing to go south again, Sun Xuanya also knew that the Flying Eagle Army would not give up and would definitely fight south again.

On the top of the city, Sun Xuanya looked at the endless wheat fields in the north, and was really worried. Like all the bandits, Sun Xuanya claimed to the outside world that he had an army of 200,000, including more than 100,000 elderly, weak, women and children, and the real soldiers were only 50,000.

Sun Xuanya's army is far less sophisticated than Wang Bo's army. Not only is it backward in equipment, but it is also much inferior in combat effectiveness. It only relies on the large number of people to defeat Wang Bo.

Sun Xuanya was very worried about the food problem. He wanted to raise more than 200,000 people. The problem of insufficient food has always troubled him. Now his food storage is not much, and ordinary people have begun to implement the rationing system. Although he complained, he had no choice but to rely on the bumper harvest of summer grain this year to solve the urgent problem. The wheat was about to mature in another month. If the Sui army marched south at this time, it would bring huge trouble to his summer harvest.

At this time, the voice of his brother Sun Zhian came from behind, "I have something urgent to see the king!"

When Sun Xuanya turned around, he saw his brother Sun Zhian holding a letter in his hand, anxiously pushing away the personal soldiers' obstruction.

"Let him come here!"

Sun Xuanya suddenly had a premonition, could it be that there was news from the Sui army?

Sun Zhian hurried forward, "Brother, it's Wang Bo's urgent letter!"

Sun Xuanya couldn't help but frowned. What did Wang Bo do when he wrote a letter? Every time Wang Bo wrote a letter or came in person, he would ask himself to kill Meng Rang. He could deal with it once or twice, but every time he asked this, it really made Sun Xuanya a little angry. Whoever he appointed had to do with him, Wang Bo, and he had to come and point fingers at him again and again.

Especially when Wang Bo defeated the Sui army last time, everyone said that Wang Bo was the lord of Langya County. This made Sun Xuanya very jealous, so since the end of the last war, Sun Xuanya has not contacted Wang Bo.

Sun Xuanya snatched the letter from his brother, opened it casually, frowned and looked at it roughly. His face slowly changed and he began to become nervous. He read the letter carefully and couldn't help but breathe a breath of air. The thing he was most worried about was that the Sui army actually gathered in Dong'an County, and this time it was Zhang Xuan as the main general.

Sun Xuanya read it twice, but there was no detailed information he wanted in the letter. He immediately said to his brother: "Where is the sender? Take him to see me!"

Soon, a letter delivery soldier was brought up and he stepped forward and knelt on one knee. "See the King!"

"Do your lord have any other message to bring to me?"

"Report to the king, there is another news that my lord just got it. But I can't be sure, so the lord told me to be humble. If the lord is interested, I can tell the lord."

"What news?" Sun Xuanya asked anxiously.

"My lord received news that the Sui army began to build a castle in Mengyinkou, but it was not certain. If the king was interested, he could send someone to take a look."

Sun Xuanya was puzzled for a moment. What did the Sui army do to build a castle in Mengyinkou? At this time, Sun Zhian carefully reminded him, "Will that grain fort be abandoned of course?"

Sun Xuanya suddenly thought of something and immediately ordered: "Get the map!"

His personal soldiers quickly spread a map in front of him, and Sun Xuanya quickly found the grain fort located in Mengshankou on the map.

The castle is called Mengyin Castle, less than fifty miles away from Fei County. It was originally a solid castle built by the Northern Qi Dynasty more than 40 years ago to store grain. Although it has been abandoned for many years, the Northern Qi Dynasty used large bluestone to build the castle. Although it was slightly damaged, it can still be used after a slight repair. Did the Sui army want to use this place to store grain?

Sun Xuanya felt a little nervous. He pondered for a moment and said to Sun Zhian: "Send an army to check it out. If possible, destroy this castle immediately."

"Abide by the order!"

Sun Zhian immediately sent his general Yang Meng to lead two thousand troops to the north quickly. He was still not relieved and personally led 500 people to respond to him.

Fei County has a complex terrain, with a large plain to the east and a plain to the north, but the terrain gradually becomes higher to the north, with hills crisscrossing, and then it enters the rolling Mengshan Mountains.

Sun Xuanya found the abandoned castle on the map, located fifty miles north of Fei County, which happened to be the junction of Ju County and Fei County, and the last mountain pass to the south of the Mengshan Mountains. After passing this castle, the terrain became flat and you could even run through cavalry, so the strategic seat of this castle is extremely important.

Zhang Xuan discovered this abandoned castle during his first southern expedition to Langya County. The failure of the first southern expedition made Zhang Xuan realize that it would be difficult for them to eliminate the rioters in Langya County without solving the logistical support problem. The strategic value of this abandoned castle was immediately highlighted.

The castle is located south of Mengshan Mountain, called Mengyin Fort. It is built with large bluestones in Mengshan Mountain. It was built in the first year of Tiantong in the Northern Qi Dynasty. It has been built in Langya County for a full fifty years. It was built in the Northern Qi Dynasty to suppress bandits. It can garrison up to 3,000 troops and store 50,000 grain stones.

After the demise of the Northern Qi Dynasty, the castle was abandoned. As time goes by, the castle was greatly damaged. The castle was overgrown with weeds and the walls collapsed in many places. However, with the arrival of a Sui army in the past few days, the castle began to be renovated again.

The castle is surrounded by huge stones, and quarrying is very convenient. A thousand Sui army and hundreds of stonemasons were jingling stones and transporting stones under the city. Large bluestones were hung up to the mountainside to restore the castle located on the mountainside.

The weeds in the castle have been removed, revealing the moss-covered foundation stone. The Sui army repaved a layer of stone slabs on the original foundation stone to dry the foundation and built more than a hundred tents on the stone slabs to serve as soldiers' camping.

In the northeast corner of the castle, two huge stone grain warehouses are under construction. Each grain warehouse can store tens of thousands of stones of grain. Twenty thousand stones of grain is enough to ensure the logistics needs of the Sui army to go south. In addition, another material warehouse needs to be built. In this way, a powerful Sui army logistics base appeared.

A simple hanging tower made of giant trees was built close to the city wall. The bluestones were hanging onto the head of the city. The broken and powdered stones were removed one by one by the soldiers, replaced with newly chiseled stones, and built with lime and rice mud. The city wall would be extremely solid.

At this time, above the city, Li Shoujie was looking at the official road in the south from afar. From the castle to the south, there were originally large wheat fields and villages, but now they were deserted. It was not until they were close to Fei County dozens of miles away, but a few days ago, the soldiers discovered spies from the thief army that were present.

This made Li Shoujie a little worried. Will the thief army come north to harass himself in the construction of the city?

Li Shoujie was from Liaodong. He was only in his early twenties and could speak fluent Goguryeo language. He followed Zhang Xuan when he was in Zhuo County and participated in all battles. He had rich experience.

He knew how to be alert, so he secretly built a warning beacon tower on the hill next to the official road twenty miles away. If a thief army heads north, the beacon tower will immediately notify it.

At this moment, Li Shoujie suddenly found three black smoke rising from the air more than ten miles away. This was a serious alarm from the beacon tower, which indicated that more than a thousand thieves had appeared.

"So ordered all brothers to return to the castle!" Li Shoujie shouted loudly.

‘Dang!Dang!Dang!’

The alarm bell was made on the castle. The Sui soldiers who were quarrying around him immediately gave up their work and evacuated into the city one after another. At the same time, the newly repaired iron gate on the castle also began to slowly close, leaving only a gap for the Sui army to withdraw.

Although the castle has not been completely repaired, the Sui army first repaired the collapsed part, making the castle's lowest height two meters, which is enough to withstand a small-scale attack. More importantly, the castle was built on the hillside, making it easier to defend and difficult to attack.

Li Shoujie turned around and saw more than a hundred tents in the city. He immediately ordered: "Put down all tents to prevent the thief army from attacking with fire!"

The soldiers put away a tent, and the city immediately became wide open. At this time, five hundred Sui soldiers had already rushed to the top of the city, raising bows and arrows, waiting for the battle.

Half an hour later, a thief army appeared on the official road more than ten miles away, like a long small black dot, which looked like only more than two thousand people, which made Li Shoujie feel relieved.

At this time, Li Shoujie changed his mind and had a new idea. If the bandits were allowed to escape back like this, it would be too cheap for them. He had the opportunity to give this bandits a heavy blow.

He immediately ordered the soldiers: "All soldiers go down to the city, and only the first team will guard the city wall!"
