As usual, there will be an opening ceremony at the beginning of the dark period and a closing ceremony at the end.

This dark period began with Liang Kai’s magic performance, and it was wonderful and well-known.

And the end is the end of the continuous input of materials from railroad mine cars.

Although it is not exciting at all, it is absolutely beautiful. The people in the mountain city are full of joy and smiles.

What else is more exciting, more exciting, happier than watching the pie fall from the sky and the piles of fuel in the warehouse?

So the people of the mountain city looked at it and of course helped push it. Before they knew it, they passed by half a day and completely forgot about the closing ceremony.

As the supplies came in from the folding point gradually decreased and the number of newcomers gradually increased, they suddenly realized that they had no time to save this matter, so they slipped over.

The dark period ended and the light period came, and the atmosphere of the entire mountain city changed.

Especially in the west of Taijieshan City, a large mountainous area quickly became a construction site. I don’t know how many people were busy on it like moving ants.

"The iron and wood chopping people are all cheering up! A meal of ten sleepers! A team of rice for one rail! A railroad track lays from here to the edge of the city, and every step is a meal... The more you make, it depends on how fast you shop."

"You guys are responsible for digging out this sunflower and trying not to hurt the roots. When you move it with a mine truck there, it will be a meal."

"You, from here to here, dig a foot deep, and the soil is piled up next to you, and lunch will be there."

"You have piled up the dirt from here to here and there to the railroad tracks, and you have lunch."

Noisy and bustle, very lively.

This is naturally the construction site of Yuanjingjia Castle.

The materials have been prepared and food and drink are almost enough, so we will naturally do our best to carry out construction.

It was not the land opposite the river that had been agreed upon. Although the land was standard, it was very inconvenient to transport materials, personnel exchanges, or guarding and defense.

Under Liang Kai's strong request, they were all placed in the west of the city. They followed the mountains to the west along the old city. They were originally large areas of farmland, forests and other land, as well as a self-built shanty town, all of which were directly planned.

Fortunately, the people in this world are simple and I don’t know what a nail house is.

In fact, it is okay to build a house outside the city, but the house cannot be built next to the city wall, because it will reduce the gap in the city wall in disguise. Therefore, it is illegal.

I heard that the planned new area will not only have Yuan Jingjia’s castle and Master Boer’s laboratory, but also have a large area to build simple houses, allowing the demolition households to move in. A group of indigenous residents are excited and happy, rushing into the house as quickly as possible to rescue some things, and even wishing to push down the house and speed up the progress.

Some of the construction materials were provided by Yuan Jingjia, some of them transported from Nanhe River, and some of them were made from local materials...

Liang Kai originally wanted to mix and show the management methods of the earth, but when he saw that it was such an advanced method of franchise and tidying up, there was really no better proposal.

Although busy and noisy, it is also in chaos and order, just like a subway station under the Star Tower and a base for advancing in another world.

So Liang Kai stopped interfering and did what he was best at doing.

============

Behind the star tower, the vat wall is open.

On a solid rock base.

A pile of black and black materials were mixed together, including two kinds of magic beast blood powder, three middle-aged refined ore powder, charcoal, a poisonous weed, a wild fruit seed, several kinds of messy bone meal, and two kinds of resin and spell casting materials... It was mixed into a ball that was as big as a palm, and it was piled up like sand.

He aimed at the pile of materials at the distance, Liang Kai outlined his hands and muttered something. A thin beam of light shot out from his hands, shooting straight from the pile of dust from more than ten or twenty meters away.

A starlight magic, focusing the beam.

"Sweep...crackling! Boom!" The pile of ash was lit in an instant, and the fire was dazzling. It burned out in less than a second, and there were also a series of explosions, like firecrackers that raised the ashes in all directions, and a unique pungent smell floated in the air.

Xiu Xiu and the cat lion rubbed their eyes in a cute manner, and tears flowed.

It was so bright at that moment! And this thing seemed to be poisonous...

【It's an explosion!】

[The combustion speed is not as fast as before, but as long as it is sealed, the power is still obvious.]

[Oh, it's so convenient in another world. There is no need for fuses or practice sprinting. It's OK to pass by a magic trick! If the earth is the same, the Heavenly Lord Nobel will not hurt himself or kill his younger brother...]

There are hot discussions in the live broadcast room.

That’s right, this is the gunpowder created by Liang Kai, the gunpowder of this world. There is gunpowder in this world, and the power is pretty good as you see in front of you.

It is also a by-product of the alchemist profession.

However, because of magic, magic is more powerful and controllable, and it is easier to use as long as it is practiced. Therefore, although it exists, it has not attracted much attention.

Only Liang Kai, who came from Earth, knew that this thing had the potential in mining mountains and mining, war and slaughter.

So after hearing about the existence of gunpowder, he immediately recruited Banana through the influence of Yuan Jing's family to recruit three alchemists with experience in this regard, as well as several trucks of gunpowder materials purchased according to their requirements.

"The purple mist grass can make people suffocate and cry and lose their combat power, but it does not help the power of the explosion." Looking at the formula, Liang Kai said decisively.

"The explosive bean seeds will explode when exposed to sunlight and fly far away. But it should not be effective for the explosion..., it just plays a symbolic meaning. Oh, it may also have lethality similar to shrapnel." Another list was cut off.

Three alchemists provide three very different recipes.

But there is only one truth, only one chemical reaction equation, so there is definitely not too much material required, and the others are redundant.

[Well, this idea is correct. The gunpowder invented in China in the early days was also a dozen or twenty kinds, and the explosion power was extremely low. Later, after studying chemical reactions, it gradually improved.]

[There are charcoal in the three recipes, this should be there, and there are also gunpowder recipes on the earth.]

[There are all monster bone powder and blood powder, and... they are several monsters with similar elements, which may really be related to elements. There are also resin and ore powder, which can be focused on matching these.]

The project team expert team and Liang Kai analyzed together, and at the same time, supercomputers are also deducing.

I still don’t understand the basic composition of the other world, so I can’t analyze it from the most fundamental point. However, supercomputers can make the most scientific and reasonable planning, allowing Liang Kaiyi to try the most time-saving and labor-saving, and draw the most scientific conclusion.

While speaking, his subordinates had already completed the arrangement of the last formula gunpowder on another rock base. Liang Kai was about to start the experiment, but when he saw Xiu Xiu and the cat lion approaching with great curiosity, as if he wanted to take a good look at how this thing emitted such strong light and heat.

Curiosity killed the cat! Liang Kai shook his head helplessly, just as he was about to keep these two guys away, suddenly someone was out of breath and ran over: "Xiaoshi!Xiaoshi! Someone made the engine you mentioned!"
Chapter completed!
