During the Sui and Tang dynasties, Youzhou's military status was very prominent. Emperor Yang www.biquge.info of the Sui Dynasty built the Linshuo Palace as a palace in Zhuo County after seven years, and used troops in Goguryeo three times after the great cause, all of which were based in Zhuo County, gathering soldiers and horses, weapons, and grain reserves. In the eighteenth year of Tang Zhenguan, he sent troops to Goguryeo, which was divided into two routes, water and land, and the land route also took Youzhou as the rear base camp.

In the middle of the Tang Dynasty, the power of the northeastern tribes was strong, and the Youzhou Festival was placed here in the second year of Xiantian to control the Xi, Khitan and other tribes.

And now, that is, in the twenty-eighth year of Kaiyuan, Youzhou is still a big state, has not yet been changed to Fanyang, is an important military and commercial town in the north, and the current Youzhou Jiedu envoy is the famous Hu An Lushan.

At this moment, in Youzhou City, in an inconspicuous tavern in Kaiyangfang, Ye Sanlang and his party were sitting in a room, discussing countermeasures.

After entering Youzhou City, through inquiry, they came to an astonishing fact, that is, it is not yet the twenty-eighth year of Kaiyuan, but the end of December of the twenty-seventh year of Kaiyuan, and there is still a week before the Shangyuan Festival.

After the initial shock, the trio has now calmed down.

Li Sihan believed that it must have been the abnormal changes that occurred through the passage connecting the Boundless Forest and the present world, which changed the exit of time and space, causing them to come to Fanyang a few weeks ago.

Since they are here, they can only rest here for a while, since there is still a week before the Shangyuan Festival, then they in this time and space should still be in Chang'an, the matter of Taibai Restaurant should happen in these days, Ye Sanlang's promotion to supervise the imperial history should also be a few days later, they can still rest in Youzhou for a few days, and they can rush to Yangzhou when the time is about the same, and they can also arrive a few days in advance.

"There's one thing I'm a little worried about, though. Bai Lingfeng said suddenly.

"What?"

"A few days ago, Zuo Prime Minister Li Shizhi impeached An Lushan for plotting rebellion, but he was suppressed by Li Xiangguo, and An Lushan is very good at slapping horses, and the emperor is also very relieved of An Lushan. However, as you saw just now, the city of Youzhou is well defended, and the Hu soldiers are very wary of outsiders, which is because there are secrets in the city. ”

"Maybe you're thinking too much, Youzhou has been a military town since ancient times, after all, there are so many border people eyeing here, and it's normal to be cautious. ”

"I'd rather I'm too sensitive, An Lushan has 90,000 troops, this is only in name, not counting the private army, and the ten major festivals in the world make him account for one-fifth of the troops. The Central Plains inland government is empty, if An Lushan and foreign tribes come to attack, my Tang Dynasty is in danger!"

"In this way, since we can still stay in Youzhou City for a few days, then I will explore the details of An Lushan with Brother Bai. ”

"It's fine. Bai Lingfeng nodded, if there was really any evidence of guilt, then he could go to the emperor to denounce An Lushan.

The three of them rested for one night, and the next day, when Li Sihan was still asleep, Ye Sanlang and Bai Lingfeng went out. At first, they walked around the city a few times and found some heavily guarded locations. Then, they set their sights on the sub-city of Youzhou City, which was where An Lushan's Youzhou Iron Cavalry was stationed, and it was also the location of his Youzhou Jiedu Mansion. However, there were also heavy troops stationed in the area where the inner city and the sub-city were found, and after discussion, they decided to explore the sub-city at night.

In the middle of the night, the huge Youzhou City fell silent, and only the sporadic sounds of beating the elderly and patrolling sentinels could be heard.

On the roofs of each square, two black figures were shuttling agilely, it was Ye Sanlang and Bai Lingfeng, with their skills, it was not a problem to enter and exit Youzhou City after changing into night clothes.

After a while, the two of them came to the roof of a house on the edge of Tongrenfang, the nearest Tongrenfang in Ion City, and lay down to look towards the gate of Zicheng. I saw that although the night was already very deep, the Hu soldiers standing guard were in good spirits, which made Bai Lingfeng very impressed, if it was the Yulin Army composed of those rich and noble children in Beijing, they would have already found a place to take a nap at this time.

However, although the sentries were very serious about guarding the city gates, such a distance was not a problem for the two of them, and they could jump directly from the roofs of the houses to the low walls.

Bai Lingfeng was about to jump up, but was pulled by Ye Sanlang.

"Don't panic, I don't think it's that simple. ”

After speaking, he used his best skill to search for qi with intention, and suddenly found that in the black and white world, the wall was surrounded by a conspicuous Yuan Qi barrier, which looked like a barrier of vigilance magic, and once someone jumped over the wall, the sorcerer would immediately know.

"It's so dangerous, fortunately I grabbed you, it seems that there is something wrong with the undefended wall, and there is a warning spell on it. ”

"The thief is really careful, so what now?

"Of course not, it seems that he really has some problems, I just learned a spell a few days ago, and I can use it here, that vigilance spell can prevent ground and air defense, but it can't prevent underground. ”

"What do you mean?" Before Bai Lingfeng could react, he saw Ye Sanlang seal with his hand, and said softly: "Little ghost carrying." ”

In an instant, he felt that his eyes were dark, and then there was a large smell of earth, and then he remembered that the legend of the Taoist priests in the rivers and lakes was a kind of thaumaturgy, called "little ghost carrying", and the effect was to escape from the pursuit of monsters or gangsters. It seems that Ye Saburo also learned this trick, but it was not used to escape, but to infiltrate.

A soft hand in front of him held him, slowly moving forward in the dark underground, and stopped from time to time to change directions, Bai Lingfeng knew that he was probing the situation on the ground in order to change direction, and it seemed that he could not speak when he performed the little ghost carrying.

Suddenly, Ye Sanlang stopped, and then, the scenery in front of him suddenly changed, as if he had suddenly come out of the dirt, and after getting used to the brightness outside, Bai Lingfeng almost shouted out.

It looked like a warehouse in front of him, with the faint flame of a few candles, he could barely see that the shelves around him were full of weapons, and there seemed to be tens of thousands of weapons in the huge warehouse, and he drew a knife that seemed to be cast in batches.

"On the way, I passed by several warehouses, I took a cursory look, they are all weapons and food, especially grain, at least 100,000 people eat for a year, and I estimate that this is not the whole of the total, in the entire Youzhou range, in addition to Youzhou City, other cities must also have accumulated. ”

Bai Lingfeng's face was both happy and worried: "Okay, let's report to the emperor soon." ”

"No, I think, it's useless, with the emperor's means, it is impossible not to know this, although it seems to be a good reason, but it can also be said that this is for the weapons and grain accumulated for the Northern Expedition to the alien race. ”

Yes, it seems that the reason is not sufficient, and only the important evidence is to find important correspondence.

"So, do you want to explore An Lushan's Youzhou Jiedu Mansion at night?"

"I can only do this, there is still a period of time before dawn, and Youzhou Jiedu Mansion is not far from here, let's go for a trip." ”

After saying that, he began to use the little ghost to carry again, and the two of them went into the ground and soon disappeared.

At this time, a mouse hiding in the corner of the wall suddenly appeared, and suddenly turned into a human form, and just as he was about to cast a spell to transmit a message, a hand suddenly appeared from the ground and grabbed his neck, and then two more people appeared from the ground, it was Ye Saburo and Bai Lingfeng just now.

The man's eyes widened, his eyes filled with doubt and fear.

"Curious why we came back again, didn't we? I found you underground just now, but unfortunately you turned into a rat at that time, and it was not easy to catch, so I planned to leave first, but you really changed back into human form to report, and it is better to arrest you at this time. ”

After speaking, he showed a fierce expression again, and said, "How much do you know about An Lushan's plot to rebel? ”

However, the other party showed an indifferent expression, which made Ye Saburo very angry and directly broke his neck.

"Brother Ye, this, this is?"

"Some of the princes have hired a special envoy to spy on the enemy and guard, and there will never be only one, let's go quickly, his companion should have known when he changed. ”

After speaking, he hurriedly grabbed Bai Lingfeng and went into the ground again.
