Since the beginning of the army, Zheng Chenggong has been working hard every day to survive in troubled times, and now it is rare to have a moment of stability, Zheng Chenggong asked Dong You to sit in the courtyard with him, and took his sons Zheng Jing and Zheng Cong to watch fireworks and firecrackers.

The fireworks bloomed in the dark sky with bright and colorful patterns, which provoked Zheng Jing, who was only 7 years old, to applaud.

The fireworks are beautiful but very short-lived, and Zheng Jing took advantage of his mother's inattention to get some firecrackers to play with.

The origin of firecrackers was first recorded in the "Divine Strange Sutra", the book said: "There are people in the deep mountains of the West, their length is more than a foot, the sex is not afraid of people, and the crime is cold and hot, and the name is mandrill." The bamboo was set on fire and hung on the ether, and the mandrill was frightened. ”

It is said that mandrills are most afraid of fire and sound, because bamboo will make a "crackling horn" sound after burning, so in order to drive away mandrills that harm people, every Chinese New Year's Eve, people will burn bamboo and explode to drive away mountain ghosts and plague gods, which is called "firecrackers".

Later, Chinese warlocks invented gunpowder, and skilled craftsmen used multiple layers of paper to tightly roll gunpowder, connected it with a fuse, and ignited it to make the explosion sound, also known as "firecrackers", using firecrackers to scare mandrills away.

In this way, year after year, the custom of setting off firecrackers, lighting red candles, beating gongs and drums to celebrate the New Year has been formed.

The term of firecrackers varies from one historical period to another, and the titles range from "firecrackers", "firecrackers", "firecrackers" to "firecrackers".

However, from ancient times to the present, a single firecracker with large volume, more gunpowder and strong explosive power is still called "firecracker".

Zheng Jing was excited, and carefully pulled out a firecracker from his arms and inserted it into the soil.

Looking at his brother's appearance, Zheng Cong followed him curiously and watched.

After Zheng Jing put it away, he took the letter incense a little, turned around and ran. Zheng Cong, who has been following his brother, is only two years old, and he has just learned to walk, so he has no time to turn around.

With a bang, the firecrackers exploded, and the shredded paper flew in all directions, and a small piece of it hit Zheng Cong's face who was stupidly in place, and he was frightened by the explosion, and he immediately pulled his throat and cried.

The crying attracted the attention of Zheng Chenggong and his wife, and they turned their heads to see that Zheng Jing was still holding a letter incense in his hand, looking at his mother Dong You in fear.

Zheng Cong couldn't stop crying, and there were still fragments of firecrackers and fireworks on the ground.

Seeing this situation, Dong Youna still didn't understand what was happening, she asked Zheng Cong's nurse to go to appease Zheng Cong, and then called Zheng Jing with a straight face and punished him for kneeling on the ancestral tablet.

Hearing the sound of firecrackers before, Zheng Chenggong was not abnormal, but when he saw the firecrackers in Zheng Jing's hand, he fell into deep thought.

When the next person took the firecrackers in Zheng Jing's arms, Zheng Chenggong said: "Give me those firecrackers!" ”

As soon as he heard Zheng Chenggong speak, Zheng Jing was so frightened that he immediately knelt down and said, "Father, the child knows that he is wrong, and he will never dare again!" ”

Seeing the scared look of his eldest son, Zheng Chenggong reached out and pulled him up. He said gently: "I don't mean to blame you, I just want to see those firecrackers." You are the eldest son, remember to take care of your younger brother next time. Got it! Okay, it's okay. Go play! ”

After speaking, Zheng Chenggong sorted out Zheng Jing's clothes and patted his head.

Seeing that Zheng Chenggong easily let go of his son who had done something wrong, Dong You said, "Husband, ......."

Seeing that Dong You was about to preach again, Zheng Chenggong hurriedly smiled and said, "It's still a child, let's talk about Chinese New Year's Eve, forget it this time." ”

Hearing that Zheng Chenggong pleaded, Dong Youcai stopped dwelling on this matter, and she said with a tiger face, "Next time there is such a thing, you will be severely punished." Don't play anymore, go to bed! ”

Zheng Jing was very happy to be exempted from punishment, but seeing that his firecrackers were taken to his father, Zheng Jing was very reluctant, and he walked back to his bedroom step by step.

After Zheng Cong comforted the nurse, he was also sent to rest.

After his sons left, Zheng Chenggong took the firecracker, looked at it carefully, and then took the letter incense handed by the next person.

After lighting the firecracker in his hand, Zheng Chenggong immediately threw it out.

With a bang, the firecracker exploded in the air. The fragments hit Zheng Chenggong's hand, and it hurt a little.

It's just a little painful, and the power is not enough!

Zheng Chenggong closed his eyes and recalled the appearance of those grenades he had seen in movies and television.

If the shell is replaced with iron from paper, the amount of gunpowder will be greatly enhanced.

Thinking of the power of those grenades, Zheng Chenggong's heart itched, and he couldn't wait to immediately let someone make a sample to try the power.

When Zheng Chenggong just wanted to call people, he thought that today was Chinese New Year's Eve, and it was very unkind to call people over to develop grenades at this time.

Zheng Chenggong had no choice but to be patient and let his subordinates remember to send someone to send someone to Feng Chengshi, who was in charge of military equipment, tomorrow morning, to come and visit.

Zheng Chenggong instructed the family to dismantle some firecrackers and concentrate all the gunpowder inside.

Because he couldn't find a suitable iron tool to install gunpowder, Zheng Chenggong had to have a few bamboos in the house cut down.

The bamboo is divided into several bamboo tubes that are more than ten centimeters long and two or three centimeters wide, and each bamboo tube retains the two ends of the section.

Have someone drill a hole the size of a thumb in the bamboo septum at one end. Then put the gunpowder in, compact it with a small wooden pole, then mix some crushed stone and pieces of iron in the gunpowder, put a fuse on it, and finally seal it with yellow mud.

At the same time, in order to make some comparisons, Zheng Chenggong also asked the small crockpots filled with salt and oil in the kitchen with gunpowder and gravel.

Zheng Chenggong looked at the baskets of "firecrackers" and "bursting tiles" prepared by the people one night. I don't know how explosive and lethal a simple grenade made of gunpowder can be, but tomorrow I will go with the officials of the Ministry of Industry to test it, and we will know the effect!
