The Imperial Palace, the small building of the West Factory,

Yang Dong stared at the map on the wall, his eyes flashing with thought.

In today's Youzhou, there are three forces. They are the remnants of the Later Jin, Great Qin and Great Zhou.

Houjin occupied the horse farm, which was a military stronghold in Youzhou. And Daqin's army was in the middle of Youzhou, blocking the waist and cutting off the retreat of the Houjin cavalry.

Among them, Gu Yuguan is the top priority.

If you can occupy the Guyu Pass, you can form a situation where one husband is the pass, and ten thousand people are not open. But now Gu Yuguan is probably already in the hands of Great Qin.

If you want to recapture Guyu Pass, you first need to let the Qin army withdraw. But how easy is it to get the Qin army to withdraw?

Yang Dong frowned slightly, and continued to look at the border between Pingzhou and Youzhou.

When the Qin army entered Youzhou, there were actually only two ways to go. One is the passage of Pingzhou, borrowing the Lingjiang waterway. The other is to borrow the road Houjin and cross the Shenyan Mountain into Youzhou.

Wait, something isn't right!

Qin State's move this time was to cut off Houjin's retreat. Therefore, they will definitely not go to Shenyan Mountain. But if they didn't go to Shenyan Mountain, it means that they chose to take the Lingjiang waterway.

But the Lingjiang waterway, isn't that a heavily guarded place in Pingzhou? Could it be that Yang Yanzao had colluded with Daqin?

Scourges, all of them are scourges!

Yang Dong frowned, looked at the map for a long time, and did not find a way to break the situation.

The Qin army is ambitious, and if they don't retreat for a day, Youzhou will not be peaceful for a day. But if the Qin army retreats, then there is a high probability that Jin Tieqi will go directly south to Youzhou and push it all the way.

If you want to stop Houjin's iron horse, you can only defend Guyu Pass. But the army of the Great Zhou ...... Hey, don't mention it!

That's it, for the sake of today's plan, you can only take one step at a time.

However, this Guyu Pass still has to find a way to take it back and hold it!

Thinking of this, Yang Dong's thoughts gradually became clearer.

"Shu Mouse!"

"Yang Gong, his subordinates are here!"

Shu mouse was on call, and his body flashed in front of Yang Dong.

"You immediately go to the Lenggong Manufacturing Institute and ask about the development of Lulao cement, and whether its hardness has been improved?"

"In addition, ask Lu Lao again, what is the output of gunpowder today."

Shu mouse immediately bowed his head and said yes, turned around and left the small building.

However, Yang Dong's brows did not stretch out, but continued to stare at the map, talking to himself.

"Alas...... Even if the cement and gunpowder production is enough, it will not be easy to transport it to Guyuguan. Unless ......"

"Wait, there you have it!"

Yang Dong's eyes lit up, and he turned around and strode towards the outside of the small building.

Perhaps there is a person who can solve the dilemma he is currently experiencing.

But the premise is that the other party has to cooperate!

About half an hour later, Yang Dong appeared outside a small courtyard in the northwest corner of the palace.

There is a row of small courtyards, but there are basically no people living in it on weekdays.

On the one hand, it is due to the fact that it has fallen into disrepair, and many of the walls have even collapsed. But there is another reason, that is, this place is really far away from the Shangqing Palace.

Most of the people who live here are the concubines of the first emperor, or some unfavored concubines. m.

Although it is not a cold palace, it also has the title of a small cold palace.

"Little barbarian, have you slept?"

Yang Dong knocked lightly on the wooden door, and after a while, there was a sound of rustling and dressing in the room.

After waiting for the tea, a very displeased voice came from inside the door.

"Yang Dong? You've come to Hongu so late, but what's the matter? ”

With a "squeak", the wooden door was opened by a white and tender jade hand.

Wan Yanyue wore maroon hair and glared at Yang Dong with a displeased expression.

"That...... Princess Wanyan, I came to visit late at night to discuss important matters. I wonder if it's convenient for me to go in? ”

"Hmmm......"

Wan Yanyue groaned for a while, and then she stared at Yang Dong, and suddenly covered her mouth and chuckled.

"Hehe, come in if you want to. Anyway, it's a eunuch, and he can't do anything about this palace! ”

"You ......"

Yang Dong's face was immediately full of anger,

Little barbarian girl, do you really think that the young master is a eunuch?

Believe it or not, Master will let you taste the horror of a six-inch giant today?

Wait a minute!

Under the cold moonlight, Yang Dong seemed to have discovered something!

His breath stagnated, and a pair of eyes were firmly locked on Wan Yanyue's chest.

Nima, don't prairie women wear underwear?

The hill is not big, but it is strong enough.

Well...... The light cherry blossom color is a bit like Takizawa-sensei......

Ahem!

"Come in, you're stunned!"

Wan Yanyue's tone was full of doubt, and she didn't realize that she was taken advantage of by Yang Dong.

"Ahem, here!"

Yang Dong coughed lightly, immediately retracted his gaze, and entered the guest hall.

The living room is not large, but the decoration is extremely luxurious. It can be seen that Yang Dong still gave a relatively good treatment to this princess of Fanbang.

"Tell me, why did you come to this palace so late?"

Wan Yanyue pinched her waist and sat down, and the faint sleepiness made her yawn.

Xiaoshan Bao trembled, and the eye-catching Dafa once again controlled Yang Dong.

Fortunately, this time Yang Dong was prepared in advance, and the moment he was controlled, he used mercury. He coughed lightly and spoke:

"Princess Wanyan, I came to visit late at night, but I have something I want to discuss with the princess."

"Less nonsense, something to say! This princess heard from the women of your big week that you can grow taller by going to bed early and getting up early. ”

But little barbarian girl, you obviously need to grow up more now!

Yang Dong said a sentence in his heart, and said with a straight face on the surface:

"If a princess wants to grow taller, it is better to drink a glass of milk before going to bed. If...... It would be even better if it could be paired with papaya......"

"What is a papaya? Why has Hongu never heard of it? ”

Wan Yanyue's beautiful eyes flashed, and the sleepiness in her crystal eyes was slightly reduced, and she was a little more curious.

"Well, there's no such thing here. If the princess wants to eat, I'm afraid she will have to go to southern Xinjiang. ”

"Speaking of which, is the princess interested in trading with Da Zhou?"

"What did you say!?"

Wan Yanyue's eyes widened and she stood up from the wooden table abruptly.

Under the action of inertia, the hill bag also jumped twice.

"You're kidding Hongu, aren't you?"

"Who doesn't know that you are heavy on agriculture and suppressing commerce in the Great Zhou, and it is strictly forbidden for caravans to trade with us Houjin."

"What, could it be that you want to take refuge in my Houjin, so you plan to take this as a vote?"

"That's fine! After all, there are too many good things in your big week, and a lot of interesting things, which we don't have at all. But...... Can you convince your majesty? ”

When Yang Dong heard this, he immediately nodded.

"Your Majesty, I naturally have a way to convince. But...... Is there a way for the princess to let your Houjin's cavalry spare the caravan? ”

"After all, today's Youzhou is still in your hands."

Some people died, but not completely......
