"It's a pity that you think too much!"

Yang Dong glanced at Yan Yue helplessly,

"Our majesty, young and vigorous, how can he want Houjin to surrender? To tell you the truth, if it weren't for the once-in-a-century flood in Luozhou, you Houjin would not have the qualifications to occupy Youzhou at all! ”

"You're just messing around!"

Wan Yanyue pursed her lips dissatisfiedly, and said indignantly:

"I rode after gold and iron, unparalleled in the world. If it weren't for the problem of food and grass, my father would have ...... long ago."

Halfway through her words, her voice suddenly stopped, and then she glared at Yang Dong with an angry face.

Seeing this, Yang Dong immediately waved his hand.

"You said it yourself, and it has nothing to do with me."

Then he took a sip of tea and continued:

"There's no point in discussing this now. To get straight to the point, I plan to go to Youzhou to do a business after a while. Are you interested in returning to your Houjin? ”

"Doing business?"

Wan Yanyue was stunned at first, and then a look of vigilance flashed on her cheeks.

"You are the favorite of His Majesty the Great Zhou, why do you want to go to Youzhou to do business? No, no, you must be hiding some kind of ulterior conspiracy. ”

"Yo, the reaction is pretty fast."

Yang Dong smiled and praised, and then continued:

"Actually, there's nothing to hide, I plan to sell the cement to Daqin in exchange for them sending troops to assist Da Zhou."

"Cement? What's that? ”

Wan Yanyue was confused, but she understood the logic.

This Xiao Dongzi clearly wants to exchange a certain item for Da Qin's support for Da Zhou.

But...... What item could be more enticing than the benefits that his father gave to Daqin? Xiao Dongzi's head, wasn't he kicked by a donkey?

Wan Yanyue couldn't help but laugh in her heart, but after a while, she frowned again.

If it were someone else, she would definitely think that this was nonsense, and there was nothing to be afraid of.

But the problem is that it was Yang Dong who proposed this plan!

Wan Yanyue's feelings for Yang Dong are very complicated. On the one hand, he admires his knowledge, and the other party is his savior; But on the other hand, she felt that he would definitely be a big problem for Houjin in the future.

The two complex emotions are intertwined, making Wan Yanyue want to be close to Yang Dong, but at the same time, she will be defensive.

Therefore, what she said about bringing Yang Dong back to the Houjin Palace was not just talking.

She just didn't have the right opportunity.

"What is that cement?"

Wan Yanyue suddenly spoke, a pair of moon-like eyes, staring at Yang Dong seriously.

Although she knew in her heart that the other party might not tell her. But with the mentality of giving it a try, he asked.

"It's not an uncommon thing."

Yang Dong smiled faintly and put on a casual posture.

"It's just a powder that, when mixed with water, forms a binder. It's like building a city wall with glutinous rice water, but the cement makes the wall stronger. ”

Hearing this, Wan Yanyue's whole person was stunned.

She is the princess of Houjin, she has been exposed to it since she was a child, and she also understands that the most troublesome thing for her father is the strong city walls of Daqin and Dazhou.

My father once said: If there is no city wall in the world, my Houjin Iron Rider will step on the world!

However, the towering and strong city wall is like a bucket of cold water, dousing the majestic ambition of the lord of the Houjin Kingdom.

Cavalry is powerful, but when faced with siege warfare, it will instantly fall into passivity.

This is also the reason why the Central Plains Dynasty has rarely been completely overthrown in history.

According to the memory of Yang Dong's previous life, it was not until the Song Dynasty that the Mongols mastered firearms and finally overthrew the Southern Song Dynasty, which was in a remote corner.

However, it is obvious that today's Houjin has not mastered the weapon of gunpowder. If you want to conquer the city, you need to make a ladder, which costs a lot of casualties and time.

"This thing must not be sold to Daqin!"

Wan Yanyue subconsciously spoke, but soon she realized that she had no right to make this request.

After all, Yang Dong is a native of the Great Zhou Dynasty, and in order to protect his country, there is nothing wrong with it.

Moreover...... This cement may not be as easy to use as he described, otherwise why not use this to strengthen the city wall of the capital of the Great Zhou Dynasty?

Holding on to the psychology of luck, Wan Yanyue opened her mouth and asked:

"Today's Youzhou is in the hands of our Houjin people. If you want to lead a caravan to contact the Great Qin people, you will inevitably set foot in the border of Youzhou. ”

"Do you want this palace to help you deal with the father of this palace?"

Speaking of this, Wan Yanyue thought that she had guessed Yang Dong's plan, and a sneer immediately appeared on her face.

"Xiao Dongzi, you are underestimating this palace too much! This palace is the princess of Houjin, and she will definitely not cooperate with your Da Zhou! Even if it's ...... You have a life-saving grace for this palace. ”

Yang Dong seemed to have expected Wan Yanyue's reaction a long time ago, and he was not in a hurry, but took another sip of tea and said unhurriedly:

"Princess Wanyan, don't be in a hurry to refuse!"

"Think about it another way, you don't have to forget that Pingzhou, my Great Zhou, also borders on Great Qin. Although it may be delayed for half a month on the way. But after the people of Daqin saw the cement, they would gladly agree to cooperate. ”

When Yan Yue heard this, a gloom flashed on her pretty face.

She knew that what Yang Dong said was true.

Even if they don't go to Youzhou, the caravan of the Great Zhou can still reach the territory of Daqin, but it will take some more time.

Thinking of this, she frowned and asked:

"In that case, why do you want to cooperate with this palace?"

"Princess Wanyan still remembers, just now I said that Houjin's cavalry has occupied Guyu Pass."

Speaking of this, Yang Dong sighed softly.

"From Guyuguan to the south of the capital, it will only take twenty days at most. Therefore, if the war cannot be stopped in time, it is conceivable that the Great Zhou will be devastated. ”

"So you want this palace to stop the cavalry sent by your father for you?"

Wan Yanyue's brows furrowed at the moment, and she gradually understood Yang Dong's plan, but because of this, she began to hesitate in her heart.

"That's right, I wonder if the princess can help with this?"

Yang Dong smiled slightly and asked.

"You think Hongu is crazy?"

Wan Yanyue sneered and immediately shook her head.

"Even if you say cement, it really works. But by the time the Great Qin reinforcements arrive, maybe your Great Zhou's capital has already been breached. Then ......"

"Princess Wanyan, I don't know if you are interested, follow me out of the palace to have a look."

Yang Dong suddenly opened his mouth and said something that was incompatible. But Wan Yanyue heard what he meant, and after a short silence, she bowed her head slightly and said:

"Okay."

……

The carriage left the palace and headed straight for the outer city.

In fact, as early as when Yang Dong was building the official road of the Luozhou Expressway, the empress also carried out the project of reinforcing the city wall with cement.

Today's Great Zhou can't afford to tear down the city wall and rebuild it.

But reinforced with cement, it can still be affordable!

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