Although Chen Letian had this undeserved sense of alienation from the palace in his heart, he quickly drove this unnecessary emotion out of his mind.

Useless things are put in the brain, and all kinds of harm are not good.

Chen Letian and Li Tong followed the two eunuchs to the Fireworks Palace in the northwest corner of the palace.

After walking for half an hour, I arrived at my destination.

Located in the northwest corner of the palace, it has been used for decades as a special place for fireworks in the palace during the New Year's holidays.

But today's saint is not interested in such a beautiful thing as fireworks, and he doesn't like fireworks that cost thousands of taels of silver in the palace every year, and feels that it is a waste of money, so since the saint succeeded to the throne, there has been no official time for fireworks in the palace.

Every New Year's holiday, if anyone is willing to pay for a few strings of firecrackers in the palace, it is up to you. It's just that the imperial court no longer pays for fireworks at this fireworks stand.

Older people in Bianjing often regret it during the festival and can no longer see the brilliant fireworks in the Fireworks Palace.

However, the wealthy businessmen who never do loss-making business in Bianjing City outside the palace often spend huge sums of money to set off fireworks on the stage and show them to the people for free, and then quietly put their own business signs next to the fireworks platform for publicity.

For this reason, the ladies and concubines of the harem, as soon as they mentioned this, they covered their chests and sighed lightly, but it was a pity.

Some old servants in the palace will also recall the grand occasion with the young ladies and concubines.

Countless fireworks bloom in the night sky at the same time, as gorgeous as spring flowers, as wonderful as brocade.

After the two fathers-in-law led them to the place, they left.

Li Tong touched his waist card and said to Chen Letian: "The waist card must be put away, one for each person, and the people guarding the palace gate have portraits." You can come in from morning to evening, no matter how familiar you are with the guards guarding the door, you have to show your waist card when you want to enter the palace. In addition, you can't enter the palace at night when the gate is closed. ”

Chen Letian nodded, indicating that he understood.

Look up at the gate of the original Fireworks Palace.

From the outside, the Fireworks Palace is divided into three floors and covers an area of about 300 acres. Eight in front and back. There are large open spaces in both the front and back yards.

Moreover, the buildings here are all fireproof, using wood that is more difficult to burn, and brushed with a layer of fireproof oil.

It is suitable for setting off fireworks, and it is also suitable for various firearms experiments.

The gate doesn't look very ornate, and it's not much different from the ordinary mansions in the palace.

There were several guards standing at the door.

Seeing Li Tong and Chen Letian, the guards bowed and saluted, Li Tong waved his hand and walked in with Chen Letian.

As soon as he entered the door, Chen Letian saw that there were many boilers smelting steel in the front yard.

In the middle of winter, these people were wearing only thin clothes in front of the boiler, sweating profusely.

In Chen Letian's letter from the unknown land, it is clear that there is a general method for smelting steel. But at the moment, it's very difficult to get the temperature up to standard. I can only try to refine it first for the time being, and at this stage, I don't want to find much good steel, and I can cultivate the feeling of these people who were originally doing fireworks.

Chen Letian came to the second courtyard again, where gunpowder was being proportioned. In fact, fireworks have existed for a long time, and the ratio of gunpowder has been relatively mature, but it has never been used in battle formations. Chen Letian's plan is that the ratio of gunpowder needs to be further optimized, and the maximum power can be produced with the smallest amount, and this trend is the direction of research.

Then there is the third courtyard, which can be seen as a gathering place for all the weapons in the world. The task of the staff here is to study the most advanced weapons of the countries. Research and see how gunpowder can be attached to these most advanced weapons, and how to use it, can increase their power.

Finally, there is the fourth courtyard, which is the meeting and office location, the place where all kinds of drawings are produced, and the place where the military advisers discuss. They were intently calculating something on paper. I didn't notice Chen Letian and Li Tong at all.

And finally, there's the largest open space. There were piles of sand and gravel in the clearing, and many pits were dug.

It is specially used for testing results for experiments.

There aren't many people here now, Li Tong said, because it's morning, everyone is preparing, and in the afternoon there will be a lot of people doing experiments here. In the last courtyard, Chen Letian saw that a very high wall had been pulled up around him, and many layers of quilts had been laid on the wall. Li Tong said that this design is for sound insulation, but because the top is too big, it is not good to cover the quilt, so it is still under consideration.

Chen Letian smiled and said, this is simple, I see you don't dig a lot of holes in the ground, you can make a very thick and soundproof cover, when you want to experiment, cover this cover, you can play the role of sound insulation. Of course, there will definitely be sound, so don't remove the quilts from the surrounding walls.

Li Tong listened to this opinion, clapped his hands and praised, saying that you are still smart, we have thought about it for several days but did not expect it, you came to take a look, and immediately solved our problem.

Chen Letian was proud on his face, but he secretly thought to himself, this is what he saw in an unknown letter, when people were testing, they used a very strong big box, we can't make such a box now, so we can only find a way to make a lid to try.

Chen Letian suddenly thought of something, and said to Li Dao: "Only some small experiments can be carried out here, if a powerful weapon is developed, it may not be safe here, but this is all in the future, if it really comes to that time, then our firearms research is estimated to be at its peak." ”

Chen Letian said, and remembered that the unknown letter said that in that world, there is an ultimate weapon. Once unleashed, it can destroy a Bianjing city. In just an instant, all the buildings and creatures in Bianjing City can be turned into powder. And what's even more terrifying is that in the next few decades, there will be no grass in this city for hundreds of miles, and there is a high chance that the children born will be crippled and have all kinds of strange and incurable diseases.

In that world, the invention and testing of such weapons were carried out in the desolate Gobi Desert, far away and uninhabited.

Chen Letian thought: Is the invention of this weapon a good thing or a bad thing for the people of the world?

The invention of powerful weapons, on the one hand, has greatly increased the combat power of a country, but at the same time, the number of deaths on the battlefield will also rise sharply.

It's like the first war, there were no weapons. In a battle, two or three people may die, but with swords, guns, swords, and halberds, hundreds or thousands of people may die in a battle.

Therefore, today's Chen Letian sometimes thinks about whether it is good or bad for him to propose the establishment of a firearms research bureau, and I am afraid it is not exhaustive.
