Lin Bai divided the four hundred or so recruits into three classes in just one afternoon, namely—archers, sword soldiers, and shield soldiers.

Then in the three arms, each is divided into ten squads, each squad has a number of ten to fifteen, and each squad selects one captain and two vice captains through an internal elimination competition.

Captains compete against each other, and the winner will be the leader of that class.

The commanders then compete with each other to elect the commander-in-chief.

After some twists and turns, the position of commander-in-chief finally fell into the hands of Xue Tiezhu.

Since then, the diversion has come to an end.

And the new officials took office three times, and on the first night of Xue Tiezhu's tenure, the recruits practiced for an hour or two more than usual.

In this regard, Lin Bai only said two words - ruthless enough.

It was late at night, and Lin Bai was still busy in the barracks dividing the martial arts secrets he had collected from the Li Mansion according to the level of his contribution value, and by the way, he also practiced and made up for the lesson.

At the moment, since he already knew that there was no harm to him in breaking through the martial arts, and he could also increase his self-preservation power, Lin Bai had no worries about cultivating.

However, these martial arts secrets are too low-level after all, according to the division of the Great Xia world, they can only belong to the 'basic skills' and are not considered exercises, and Lin Bai can only practice the skills of practicing power and the flexibility of the moves, and the effect is not very great.

was practicing, but the palm of the book walked in from outside.

"What happened to your face?"

The palm of the book, who originally wanted to report on the work related to Wuguan Road, couldn't help but ask in surprise after seeing Lin Bai's swollen face.

Lin Bai was speechless for a while, stroked the hair on his temples, and couldn't help but want to say, you only saw it now?

"Can you assume you didn't see it?"

Treasurer: "......"

"The saltpeter ordered by the county order has arrived, and I took out a piece to check the quality of the county order. ”

As he spoke, the palm book stepped forward and placed the colorless crystal in his hand on Lin Bai's table.

Saltpeter arrived?

Lin Bai just stepped forward, and he smelled the bitter taste, and it was estimated that it was saltpeter.

In other words, the development of gunpowder can be carried out?

Is the player's Nightmare dungeon difficulty getting worse again?

"Good. ”

Ever since the thought of gunpowder popped up in his mind that day, Lin Bai began to recall the formula of gunpowder.

According to Lin Bai's memory, the principle of explosive gunpowder is potassium nitrate, the main component of saltpeter, which reacts with carbon and sulfur, and releases a large amount of nitrogen and carbon dioxide after combustion, which expands rapidly in a short period of time so it produces an explosive effect.

In other words, in addition to saltpeter, two raw materials, charcoal and sulfur, are needed.

However, compared to saltpeter, charcoal and sulfur are more common, and there are many in the garrison.

Hehe, I didn't expect me Lin Bai to be so knowledgeable, right?

"Boss, you can help me find some more carbon and sulfur, the sooner the better. ”

Lin Bai couldn't wait to verify whether his memory was wrong, not to mention that once the gunpowder was successfully developed, it would also improve the combat effectiveness of the military camp.

However, the bookkeeper stood still and did not move, his expression was a little embarrassed, and he wanted to speak several times, and finally dared to hand a letter to Lin Bai.

"The county order you can take a look, it's from the county seat. ”

"The county seat?"

Lin Bai chuckled in his heart, and an ominous premonition arose in an instant.

With doubts, Lin Bai opened the creed and saw that the long note simply read-

"Come to see me at the county magistrate's office within three days. ”

The signature of the payment is Zhang Yang, which is the name of the Jiangyang County Guard.

The county guard of Jiangyang told me to see him in three days?

And it was in the form of a private note, and no special messenger was sent to inform it.

Could it be a private matter?

Lin Bai immediately felt strange.

When it comes to personal matters, there is no selfish relationship between himself and the county guard Zhang Yang, at most, when he went to the county town to make an annual summary, he frowned with his daughter twice.

Oh yes, his daughter!

Could it be ...... Is it his daughter who never forgets me, thinks about it day and night, and finally becomes lovesick?

It's not right, this is not an unsightly thing, I'm white, handsome and powerful, isn't it normal to like me? Isn't it natural to send a sedan chair over? Need to be so sneaky?

Then it is very likely to be a private matter that is not visible.

Speaking of being unsightly, Lin Bai thought of the collusion between the county guard and the Li Mansion.

After all, relying on the support of the county guard, the Li Mansion has been the soil emperor for several years.

You said that he Jiangyang County Guard didn't get enough benefits from it, do you believe it?

But Li Honda was only solved last night, and even if this matter spreads quickly, it can only reach the ears of his county guard today, but at this time, he has already received the summons creed, is it too fast?

Lin Bai felt that something was wrong.

But no matter what, Lin Bai would definitely not be able to leave Qingshan County within three days.

If you leave Qingshan County without permission during the mission, you will be treated as an escape and will be directly erased by the system.

What to do?

Before completing the task, Lin Bai would definitely not be able to go to the county guard's mansion.

But if he didn't go, if the county guard started a fire, it would still be a lot of trouble for Lin Bai.

After all, it was the boss who said it......

"Send me the charcoal and brimstone when you are ready, and besides, who gave you this creed?"

"It's from carrier pigeons. ”

"What about carrier pigeons?"

"It was beaten down and roasted by Tie Han as game. ”

Lin Bai: "......"

The originally gloomy eyes suddenly became certain, and Lin Bai's pupils gradually dilated, and he was stunned for almost two breaths.

Cattle batches.

Unexpectedly, Tie Han gave Lin Bai another surprise.

No wonder I said that the note given to me by the county guard ended up in the hands of your bookkeeper.

"Does Tie Han know about this?"

"He couldn't read, and I didn't dare tell him. ”

"Well, don't mention this matter to anyone, as if it didn't happen, understand?Besides, you should immediately summarize what has happened in the past two days, write a letter to the county guard, and send someone to the county guard early tomorrow morning. ”

After a pause, Lin Bai added:

"It's better to find someone who has nothing to do with the barracks. ”

"Understood. ”

The bookkeeper nodded.

"Okay, you've been working hard during this time, there are still a few empty rooms in the county office, if you want, you can move over with your daughter. ”

Lin Bai said as if he didn't care, but he was secretly observing the expression of the palm.

When the palm of the book heard this, his face was happy, and he immediately bowed to Lin Bai:

"Thank you for the kindness of the county order. ”

Today, he knew about Tie Han's move into the county office, and he was a little unbalanced in his heart, but now he is much more comfortable.

Lin Bai snorted weakly, and asked the palm book with a flickering look in his eyes:

"Really?"

Treasurer: "......"

How do you feel like you've kept up with a thief ship, and you're still a little troubled?

"You go and get busy, just wait for someone to bring me charcoal and brimstone. ”

After the master left, Lin Bai continued to divide the contribution points of the martial arts secrets according to the rank, and planned to announce the relevant rules in the barracks tomorrow.

During this period, the bookkeeper sent the written letter to Lin Bai for a look, and after Lin Bai felt that there was no problem, the bookkeeper found someone to help send it to the county guard mansion overnight.

After a while, someone brought charcoal and sulfur to Lin Bai.

In the middle of the night, Lin Bai sat alone at the table and began the first scientifically significant exploration experiment in his life......
