Command the kobolds to decorate the stage and set up a bonfire. Jia Zhengjin always felt that something was missing.

What exactly is missing from a grand gala?

Suddenly an inspiration came to my mind - fireworks!

He immediately ran to the grocery store and found the proprietress "Do you sell fireworks here?"

"What are the fireworks?" said Winnie, the proprietress of the grocery store, shaking her head, "The goods here are different every day, and even I can't figure it out myself!"

Jia Zhengjin carefully looked at all the goods, and indeed couldn't find the fireworks. However, it cost 5 gold coins to buy a drawing for the production of leather sofa furniture.

Since you don't have to sell it, you can only find a way to do it yourself.

The last time he killed Tie Beiqiu, Jia Zhengjin had already learned the gunpowder formula.

The materials used to synthesize gunpowder were saltpeter ore and coal.

There is a lot of coal, and Jia Zhengjin's own residential building can harvest a lot after cooking every day. Not to mention the coal left over from the daily lives of more than 1,000 villagers and town guards throughout the city in warehouses.

Then the only thing needed now is saltpeter mines!

He left the city on his own and went to the mines to bring out the shapeshifters stationed there.

There was no saltpeter in the mine, and he needed to search further afield.

Ride a shapeshifter, flap your wings and fly high into the sky to start circling the forest.

There are flocks of giant birds in the sky above the forest, groups of creatures that resemble pterosaurs, and winged foxes hunting pterosaurs.

Of course, these otherworldly creatures will actively avoid the shapeshifter, convinced of its "dragon" identity.

Jia Zhengjin turned on the skill of finding ore veins, carefully searching every inch of land that flew by. There are iron and copper mines everywhere in the forest, and then there are relatively few gold mines and silver mines, but they can also be seen.

Other veins are very rare.

After searching for a long time, just when he felt that there was no hope, a saltpeter mine that was not very obvious appeared in front of him.

Excited, he hurriedly drove the shapeshifter to land.

It is very far from the city, and only faint traces of the city wall can be seen when you fly high into the air.

There are also a lot of weird and dangerous creatures around, but they will keep their distance from the fake dragons, and try to stay away!

However, next to the saltpeter mine, there is also a nest of wild kobolds.

In the face of the transformation of the transformation into the fake dragon, all the kobolds huddled in the lair and trembled, not daring to come out at all.

Mining is important, but kobolds are experience!

Seeing that they were all hiding in the cave and did not dare to come out, Jia Zhengjin took out some stone bricks from his backpack and blocked most of the entrance and exit of the kobold's lair, leaving only one hole.

Since the inside of the lair is connected, he has the shapeshifters breathe fire into the hole.

"Usu~~" The shapeshifter received the order and immediately walked in front of the lair, opening its mouth and spitting out a scorching pillar of fire.

As a result, the entire kobold nest was engulfed in flames and turned into a furnace.

The kobolds were roasted in their lair, and they tried to escape. It turned out that most of the holes were blocked by stone bricks, and they had to grope their way to the only exit one after another.

However, the shapeshifter was waiting at the exit, and a kobold came out, and immediately a mouthful of flames erupted.

Stuffed inside and burned to death, and burned to death when running outside, these kobolds have no ability to resist at all in the face of shapeshifters who have learned to breathe fire!

Jia Zhengjin kept receiving message prompts, and an uncountable 30 experience points were swiping the screen. His experience bar is also rising rapidly, this new way of blocking doors and farming monsters is simply cool!

There were one or two thousand wild kobolds in the lair, and before he knew it, Jia Zhengjin had risen to level 11. What a surprise!

When you finally receive a message that your experience has increased by 500, you will know that the entire kobold in the nest has been emptied. However, he can't enter it at all to loot now, so he can only leave it like this for now, and wait until it cools down!

Have the shapeshifters guard nearby. Jia Zhengjin added skill points to unlock the alchemy laboratory, then took out a normal-quality iron pickaxe from his backpack and hurried to dig saltpeter mines.

A vein of saltpeter mine, located in the cave terrain below a cliff.

The cave was pitch black, and nothing could be seen. So Jia Zhengjin took out the torch to illuminate.

Finding the location of the saltpeter mine, placing the torch in it, he immediately raised his pickaxe to mine.

【NEWS】You have obtained saltpeter mines!

【NEWS】You have obtained saltpeter mines......

Saltpeter ore is much easier to collect than other ores, and basically every pickaxe you go down can get a piece.

It didn't take long for him to hollow out more than 300 saltpeter mines near the entrance of the cave.

Jia Zhengjin, who was still unsatisfied, took the torch and wanted to go further into the cave. However, at this moment, a dark shadow suddenly appeared and rushed towards him.

"Instantaneously retreat!!" Jia Zhengjin sensed that something was wrong, and immediately used his life-saving skill to move back quickly.

The shadow leapt into the air, quickly melting into the darkness and vanishing.

Although it was only for a short moment, Jia Zhengjin could see the general outline of this black shadow clearly. If I had to describe it, it resembled a black slime, and it was very large and agile.

Not knowing the strength of the other party, he exited the cave first for safety.

The shapeshifters are too big to even get their heads into the cave, otherwise would they have to worry about any black slimes?

"Make fireworks, these should be enough, right?" After glancing at the more than 300 saltpeter mines in the virtual backpack, Jia Zhengjin decided to give up digging more ore first. Wait for the next time you come back, bring Dolma, Buddy, Wolf and Carl, and then bring the kobold troops to rush in, and I don't believe that this black slime is not dead!

However, before returning to the city, you need to loot the loot in the kobolds' lair!

Finally waiting for the temperature to cool down in the kobold's lair, Jia Zhengjin bent down from the only entrance and exit.

It was densely packed with charred kobold corpses, and he groped through them one by one.

The low-level kobolds are all low-grade and inferior wooden sticks, but there are also some simple materials such as iron ore, wood, ropes, stones, etc. Although the mosquito is small, it is also meat, and he did not let it go at all.

Thousands of dogs and meat people have produced a perfect wooden stick, but it doesn't have any eggs!

After shuttling back and forth through the labyrinthine caves, it took a lot of effort for him to finally find the corpse of the kobold leader in the deepest part of the country, and next to the kobold leader was a golden treasure chest!

Just like the first kobold lair, the main loot is on the boss or in the chest!
