After deciding all the generals of the Northern Expedition, Xiao Zhengtai came to the arsenal to check the production progress of artillery and gunpowder!

"Little boy, you can rest assured, in three days, all the artillery will be made, and the ammunition can also be made, and it can be sent to the Huns with grain and grass in the future!"

After seeing Xiao Zhengtai, Huang Yuan saluted respectfully and reported the progress.

Since Xiao Zhengtai ordered a large number of artillery pieces, he stayed in the arsenal almost all of the time, except for the time to eat and sleep, supervising the production of craftsmen, for fear of a little accident!

"Good! Go back and find a few reliable craftsmen and follow Ben Gongzi on the expedition! ”

Xiao Zhengtai glanced at the busy craftsmen and spoke.

"Expedition...... And bring craftsmen with you? ”

Huang Yuan looked confused.

"That's right, if you want to do it, you can do it, don't ask so much!"

"Yes!"

"By the way, this drawing is for you, go back and bring someone to build it according to the drawing!"

After turning around in the arsenal, Xiao Zhengtai took out a stack of papers from his arms and handed it to Huang Yuan.

"This ...... Is it a ship? ”

Huang Yuan took the drawing, and his eyes immediately fell on the first drawing.

The magnificent ship immediately attracted his attention!

There are many craftsmen under his command, many of whom can build ships, but this is the first time he has seen such a ship!

According to the size marked on the drawing, it is definitely a super large building ship!

Huang Yuan stared at the drawings tightly, his brows furrowing deeper and deeper, "Little boy, do you need to use iron to build this huge building ship?" ”

As we all know, only wood is spliced together to float on the water, and iron is simply not good!

Not to mention such a big building ship, even if the iron sword falls into the water, it will sink!

So when he saw the mark behind the material, the whole person was immediately blinded!

"That's right, this is called a warship, it's not easy to develop, you take it back and study it slowly, during the time when this son is away, you have to study the steam engine first!"

This drawing was the one he had been looking through for a long time in the universal search and had drawn it.

Now the production of iron is gradually increasing, and the craftsmen are fully equipped to build warships!

So before he set out on the expedition, he handed over the drawings to Huang Yuan and asked him to study them first!

In the future, when I go overseas, I will definitely use it!

"Yes!"

Huang Yuan nodded and responded.

Since the little boy said that the iron ship can float, then maybe it can!

After all, the little boy's idea is not something that these elm heads can think of!

"Little boy...... Little boy, it's not good! ”

At this moment, Cao Shen suddenly ran over, and panting, looking at it like there was an urgent report.

Ying Feiyu now has a lot of property, and if anyone wants to find him on weekdays, they can only pray in their hearts that he is in the palace or the courtyard.

If there are no two places, then consider yourself unlucky and wait to break your leg!

"What's wrong?"

Xiao Zhengtai asked casually.

"Oh no...... Those Hun envoys plan to escape! ”

Cao Shen paused, clutched his heaving chest, and breathed heavily.

"Poof......

However, when he heard that the envoy was going to escape, Xiao Zhengtai not only did not feel a trace of nervousness, but covered his mouth and laughed.

"They are in the capital of my Great Qin, and under heavy defense, they actually want to escape?"

It's as if he's heard some joke.

Although the envoys brought more than 100 people when they came, compared with the hundreds of thousands of garrisons of Great Qin, they were not worth mentioning at all, and if they wanted to break through, they would definitely be turned into hedgehogs by Great Qin's Goza!

"That's right, they seem to have heard something, they have been panicking since noon, and after a while, they got together, and their subordinates were afraid that they didn't hold back any good fart, so they changed shifts with the guards at the door and overheard their conversation!"

Cao Shen gave his hand with a nervous face.

"What did you say?"

Xiao Zhengtai still had that breezy expression, and slowly paced towards the outside of the arsenal.

Huang Yuan stayed in the factory very sensibly, continued to supervise the work of the craftsmen, and took out the drawings from his arms to study them carefully when he was free!

"They deliberately avoided it, and their subordinates didn't listen very seriously, but there is one thing I really heard, it seems that someone will pick them up in the next two days and help them escape!"

"Panic since noon today? Anyone else answered? ”

Out of the arsenal, Xiao Zhengtai muttered suspiciously.

The Xiongnu should have done a lot of work in Xianyang, but most of them should be disguised as civilians, and the number will not be too many, even if they are all gathered together, it is impossible to have the courage to compete with hundreds of thousands of garrisons!

If it weren't for these people, who would be their answer?

"This subordinate doesn't know ......!"

Cao Shen shook his head, suddenly seemed to think of something, and continued: "Oh! By the way, these Hun envoys wandered in the streets in the morning, and accidentally ran into the prime minister who had just come down from the early dynasty, and after a few words of greeting, they separated, and then the envoys hurriedly returned to the official post, and after that, they began to panic one by one! ”

"Haha! So that's it! ”

Hearing him say this, Xiao Zhengtai suddenly understood.

No wonder Kang Anping said that in the past few days, the Xiongnu envoys suddenly acted recklessly, harassing the people who set up stalls on the streets every day, and also molesting women from good families.

It turns out that these are just their means to cover up people's eyes, and they are nothing more than to pave the way for today's meeting with Li Si on the street!

Let's just say it! At the banquet that day, he had almost killed the sharpness of these envoys, why did they suddenly become rampant?

Li Si, the old man, really didn't plan to do well, not only wrote a letter to the Xiongnu Shan Yu to expose the weakness of Daqin, but also told the Xiongnu the reason why he dragged the envoys to stay, and now he has to help these envoys escape?

However, with his current status and status, it is indeed not difficult to get a few people out of the city!

"What? Could it be that the little boy knows who the person who answered them is? ”

Cao Shen's eyes lit up, and he admired it even more in his heart.

Just listening to what he said, the little boy had already guessed the person who answered!

"As I expected, it should be Li Si!"

"Prime Minister?"

Cao Shen's mouth was open, and he was shocked.

As the prime minister of Great Qin, he actually wants to help those barbarians escape?

When they escaped from the city, they must have instigated the Xiongnu to start a war at the first time, and then Daqin Ke was in a passive state, and the chances of victory were suddenly much smaller!

"So what do we do now? But do you want to play Your Majesty and kill them all? ”

"No! We don't have any evidence of their collusion yet, so you go back and keep an eye on their every move, and if you find evidence of their collusion, you will immediately detain them!" ”

Xiao Zhengtai immediately refused.

At this time, the amount of artillery and ammunition produced was not enough, and it was necessary to stabilize the envoys for a few more days.

And the evidence of Li Si's collusion with the Xiongnu is in those envoys, if you are in a hurry to bring down Li Si, you will inevitably get the letter from the Xiongnu, so as to startle the snake, and the gains outweigh the losses!

However, he must not let these envoys escape, and he must keep an eye on them!
