Cheng Chuxue was a little puzzled: "What is the difference between this soil and sawdust? Are they both sealed?"

Liu Ruiting shook her head and explained: "Of course it's different!

If it is sealed with soil? Then when the iron cone drills through the soil, the soil will break and cannot act as a sealing function.

Even if the sealed soil is lucky enough to not be broken, the soil is not elastic and cannot hinder the lead of the firecracker.

And using sawdust can completely avoid the above problems!”

Cheng Chuxue suddenly realized: "So that's it? It seems that details are really important."

Brother Li Ying curled his lips, picked up the lead of a firecracker and shook it.

At this moment, the lead wire that had just been inserted did not disconnect from the firecrackers.

Brother Li Ying also nodded and exclaimed: "It's true that you have to use sawdust!

If you use soil? Just now, Li Chenghua used that metal rod to squeeze it, and the soil would break! It would not be stuck in the lead."

Li Chenghua, who was busy, looked up and said to Brother Li Ying, "Oh, Brother Li Ying is good! He still knows how to observe and think? I always thought you were brainless."

"Who...who has no brains?"

Although I don’t know what [brain] is?

But Brother Li Ying knew that Li Chenghua's words were definitely not praising her.

So, of course she had to fight back immediately.

Li Chenghua curled his lips and said to Wu Mei: "Mei'er, go and light a piece of incense!"

"good!"

Wu Mei quickly brought a stick of incense.

Li Chenghua took the incense and shook his head and said, "This incense is not good, it's hollow inside.

We are going to Ganye Temple and Wulu Temple these days?

It seems that it’s time to make a solid fragrance come out!”

After sighing, Li Chenghua arranged these [firecrackers] in a row according to the number.

Looking at the words 123456789... firecrackers with different numbers?

Except for Liu Ruiting, several other beauties do not know such numbers.

But they have a feeling of being unaware of it?

I feel that this type of [symbol] used for marking may be very important.

At this moment, Li Chenghua turned his head and said, "Get back a little. These firecrackers are not paper. If the bamboo is broken, it may hurt people."

Of course, firecrackers from later generations were rolled out of paper, and gunpowder was added.

However, in the Tang Dynasty, how expensive is paper?

Of course, Li Chenghua could not use paper to roll firecrackers, he could only use bamboo.

Of course, because of the firecrackers problem, Li Chenghua made up his mind to make paper!

What?

Papermaking and printing technology to attack the aristocratic families?

Thinking too much!

Li Chenghua just wanted to make some rough paper, just roll firecrackers.

As for something else?

Haha, unless you have been dying with the aristocratic family - otherwise, taking out papermaking and printing is looking for death!

Seeing that everyone took more than ten steps back, Li Chenghua lit the No. 1 firecracker!

"Bang!!!"

A crisp sound suddenly came from the garden of Mingyue Tower!

Accompanied by a burst of white smoke, everyone saw the thin bamboo that was blown into pieces and flew in the air!

"Ah! What a loud noise!"

"Yes, this sounds much louder than burning the [poke]!"

"If this [firecracker] was set off during the Spring Festival? It would definitely be very lively!"

Looking at the surprised beauties?

Li Chenghua curled his lips and thought to himself that you little ladies who are unsavvy.

Compared with the firecrackers of this kind of experimental nature, the powerful firecrackers in rural areas with electric light are far inferior to those of the 21st century!

Next, Li Chenghua recorded the listening, visual, loudness and other data of the No. 1 firecracker, and continued to ignite the No. 2 firecracker!

After dozens of firecrackers were set off, a group of beauties in the garden had already covered their ears.

However, Brother Li Ying rubbed his ears, but said unconvincedly: "Li Chenghua, you are not as loud as you imagined!"

Lee Seung-hua glared at her and said, "What do you mean? Do you still want to hear firecrackers like thunder?"

When Brother Li Ying heard this, his eyes lit up, "Ah, so, can you create firecrackers as loud as thunder? Humph, I don't believe it!"

Lee Seung-hwa suddenly looked at Brother Lee Young and then smiled and said, "Don't you believe it? Haha, do you want to make a bet?
