A challenge from the Bright Moon Faction.

Han Yuliang knew that he couldn't hide.

Since you can't hide, let's have a good fight.

It has been a year and a half since I came to this world, half a year to adapt to the laws of this world in a deep sleep (as Fei Rui said), and a year to study and fight in Fire Seal City.

Although Han Yuliang's sense of substitution for this world is still very weak, he also knows it. If you want to survive in this world, if you want to find the possibility of going back, then the battle is inevitable.

Since it is inevitable, that one moves forward.

But his current rank is too low, and if he wants to win, he will have to think of some other way.

There are certain things that he wanted to try when he was in Fire Seal City, but he never had the chance. Now......

After class.

"Ella, do you know which alchemy workshop sells a lot of accelerants? It's cheap!" Han Yuliang pulled Ella outside the academy after class.

Because Ella has to work and study, she is very familiar with all places in Mingyue City, and after listening to Han Yuliang's question, she immediately nodded: "I know, what do you want to do? Accelerants can only be used for alchemy, do you want to make gold?"

Han Yuliang shook his head and didn't answer, and took out a gold coin: "Can you do me a favor?"

Ella nodded vigorously: "You say!"

"Help me buy 50 silver coins for the accelerant, then 10 silver coins for saltpeter, and the rest for all the flame pollen, okay?"

Ella didn't ask Han Yuliang what he was going to do, patted his chest and said, "Okay, I understand!"

So saying, he ran away.

In fact, Han Yuliang wanted to give Ella some errand fees, but thinking of Ella's character, he had to give up in the end.

As soon as Ella left, Luo Liya came up: "You want to fight with the people sent by Mingyue, what's going on?"

Han Yuliang said the matter in a relaxed tone.

The dissatisfaction in Luo Liya's eyes flashed: "Lingjie, this bastard, is becoming more and more arrogant." Don't worry, I'll take care of it for you!"

Han Yuliang grabbed her: "No, you just need to help me do another thing!"

He muttered a few words in Loria's ear.

Luo Liya's eyes widened: "You, you, you are amazing!"

Han Yuliang smiled: "I'm just protecting." How's that? Can you help me?"

Luo Liya laughed: "Such an interesting thing, even if you are not my friend, I will help you." What's more, we're friends!"

The future duchess laughed and patted Han Yuliang's shoulder, shook her long legs and turned to leave.

Han Yuliang also had a good impression of this bold girl, shook his head and smiled, and turned to find Talina again.

He's not afraid of challenges, but endless entanglement isn't what he likes. Therefore, it is necessary to punch the name out at once.

Knock on the mountain and shake the tiger!

In the afternoon, Ella came back with a cart of things.

Han Yuliang's eyes were straight at that time: "So many?"

Ella nodded, "Of course, these things are cheap." Accelerants are only used by alchemists and blacksmiths, and are included in all alchemists' introductory works. There are a lot of saltpeter and leather merchants, and flame pollen is also a very good thing, and it is very cheap!"

Han Yuliang twitched the corners of his mouth, and then asked about the price of some common things, and finally knew that the hundred gold coins that Hart gave him were actually a huge amount of money.

At least for his current strength and identity, it is definitely a huge amount of money.

"Well, thank you. I'm going to prepare for the challenge for the next two days, and when I'm ready, I'll invite you to eat something delicious!" Han Yuliang patted Ella's head as if he was facing a little sister.

The expression on Ella's face surged up again: "Yes, I'm very happy to be able to help you!"

Han Yuliang pulled a cart of things and went to the alchemy studio that Talina had given him special approval.

This world is not the same as the earth.

When he was in Fire Seal City, Han Yuliang tried to make gunpowder, not only the most primitive HEI gunpowder, but also high-grade chemical gunpowder.

As a former scout, Han Yuliang still has this ability.

But the world is different, and there are things that are different.

Gunpowder made according to the earth's recipe can only be used as ordinary fuel, and the effect is not much better than the accelerant unique to this world.

But after more than a year of testing, Han Yuliang still found a "gunpowder" that could barely be used.

This gunpowder does not explode, but it does deflagrate, instantly increasing the temperature of the flame by more than ten times.

And the manufacturing aspect is also very simple, even if he doesn't understand real alchemy, Han Yuliang has made enough of what he needs in one night.

The next day, Han Yuliang used a gold coin to rent a three-year container in the academy's warehouse, and put excess materials and various things in it.

In this way, there is no need to worry about loss, and more importantly, there is no need to worry about someone coveting his "gunpowder".

In the next few days, Han Yuliang went to class, studied, and practiced on time every day, and in the last two days, he rented a training room and conducted some training very mysteriously.

Time flies.

Seven days are up.

"Except for buying some alchemy materials on the first day, haven't you made any other moves?" Ling Jie kept asking people to inquire about Han Yuliang's movements.

But even if he had a list of the materials, he didn't know what they could be used for.

The worldview is the biggest barrier in front of him.

Even if he asked his students who knew alchemy to experiment, it would not be fruitful.

After all, the three materials are not stacked together, and it is impossible to produce results without formula, proportion, and refining order.

Moreover, there is something in this world that people in this world can't even think of.

Egg white.

Han Yuliang was mixed and refined by the method of wet gunpowder.

And because of the difference in worldview, people in this world will not think of this at all.

It's as if earthlings saw lightning from the natural world, and finally thought of using electricity to act as an energy source for the entire civilization.

And in this world, when people see lightning, they think about how to use it to attack. As for energy, energy mines, monster cores, rune circles, all kinds of them, who would have thought that electricity could be used as an energy source?

"Hmph, it doesn't matter. What can we do with just a blue-level entry?Have our people already arranged it?" Ling Jie snorted coldly, deciding to ignore the incomprehensible things at hand.

"Yes!"

"Okay, let's go!"

At this time, one of his subordinates suddenly ran in sweating: "Childe, it's not good!"

"What's the matter? so flustered, is it still a bit aristocratic?" Ling Jie glanced at his subordinates dissatisfied.

"The city, all the nobles of the city have come. Even the lord of the castle came. I don't know who got the news out. The subordinate gasped for air.

Ling Jie's pupils contracted into needles for a moment: "What?"
