In ancient times, every household had to burn bamboo, making a popping sound, in order to drive away the plague god, this tradition has a long history, so Xiao Yao decided to make some fireworks and firecrackers, after all, there must be fireworks during the New Year, and burning firecrackers will feel the flavor of the New Year.

It is very simple to make firecrackers, for safety, you must first spray the black powder, insert the lead, wrap it in red paper, then roll it up to the size of a little finger, and finally use a long lead to string together the small cannonballs, and after it is air-dried, then wrap it in a square with big red paper and it will be successful!

Zu Yuan looked at these small red cannons, and was a little curious, this little paper roll would really make a louder sound than the burning bamboo?

Xiao Yao smiled, picked up a pack of cannons and threw it on, and it suddenly crackled and exploded, so frightened that Zu Yuan and they all covered their ears, and after a burst of smoke dissipated, there were red confetti all over the ground!

"How? It's loud enough, what kind of plague god decays, demons and monsters will scare away, right? And the ground is full of red paper, don't you think it's very festive? Xiao Yao asked with a smile.

Zu Yuan, whose ears were still buzzing, couldn't help but nodded, his eyes were full of incredulity, these small paper rolls exploded, and they were really louder than thunder.

The production of fireworks is a bit complicated, ancient fireworks are developed on the basis of gunpowder, alchemists will add different materials in the process of alchemy, which contains some special metal salts, so in the combustion process to show different colors, so gorgeous and colorful fireworks appeared.

Xiao Yao first added different ore powders to gunpowder to burn to determine their color, and then added these ore powders to gunpowder and a small amount of wet mud in a certain proportion and formed small balls one by one, and added these small balls to the large group of gunpowder, and then wrapped them in thick paper, inserted the lead, and finally air-dried, and the bright beads of fireworks were created.

As for the launch tube, Xiao Yao chose to use a thick bamboo tube, more than two feet long, to open up the bamboo inside, seal the bottom end with soil, pour in a certain amount of propellant and insert the lead, and then put the fireworks bright beads into it, seal the mouth of the cylinder with paper and paste, and then wrap it with red paper outside, and a homemade firework was created!

It was getting late, and in the open space outside the iron workshop, Xiao Yao was testing fireworks: light the fuse, bang! The bright beads shot out of the bamboo tube flew to a height of more than ten zhang with a Martian tail, and then with a bang, the bright beads exploded, shooting sparks of various colors in all directions!

Although it was a bit simple, they had already stunned Zu Yuan and them, and at the same time, they all knelt down and bowed to Xiao Yao: the lord actually had such a divine skill, and he could make such a beautiful and dazzling spark bloom in the air!

Xiao Yao, who felt that it was not enjoyable enough, connected several fireworks with leads, and then tied them together to make an effect that could fire a salvo in bursts, and then continued to test fire: Bang bang bang! The fireballs continue to rise into the air, bang bang bang! Colorful and dazzling fireworks bloom in the air, making people fascinated to watch!

"Childe really has the magic skill of earth-shattering ghosts and gods, and he can make these gunpowders emit different colors of fire! It's so pretty! "Zu Yuan, as the first person in the history of appreciating fireworks, is very excited!

"Haha, it's good-looking, different ores have different operations, and they can also emit different colors of light when burned, now you understand why I like to collect different ores, right?" Xiao Yao briefly explained the principle of fireworks.

"Childe's sugar making method has opened the eyes of his subordinates before, and now these fireworks like fairy spells have made his subordinates even more impressed!" Zu Yuan patted his ass and said.

"I have already taught you the method of manufacturing, you now immediately arrange manpower to make a large number of these fireworks and firecrackers, and then present them to the emperor and King Xing, and the prince will also send some over, I believe they will be as excited as you when they see such a beautiful scenery! When the time comes, General Motors will definitely be in the limelight again! Xiao Yao commanded.

"My subordinates will do it immediately, I believe that the emperor will be very happy, and then it will be promoted to the people, with the spirit of those high-ranking officials and businessmen, we will definitely make a lot of money!" Zu Yuan's business acumen thinks quickly.

After a busy day, Xiao Yao explained all the work and was about to return to the Xiao family, Zu Yuan grabbed Xiao Yao and said: "It's getting late, Gongzi is going back alone, my subordinates are a little worried, it's better for me to personally send Gongzi back, plus why Gongzi went back late, if I am here, Lord Xiao will be easy to deal with." ”

Xiao Yao shook his head and said: "No, making these fireworks and firecrackers is dangerous work, I can only rest assured that you are here to personally supervise them!" But it's okay, I should have to come here every day during this time, and it's convenient to have someone to do things with me! In this way, you find two people to send me back, you have a guard here named Li Dahu, I think he is quite clever! ”

Zu Yuan nodded and immediately went to arrange, and after a while, Li Dahu and another young man who was somewhat similar to him were brought to Xiao Yao.

"Li Dahu meets his son! This is my younger brother, Li Erhu! Knowing that I wanted to escort my son, I called him too, and the two of us brothers grew up together since we were children and practiced martial arts together, so it was even more powerful to fight together! Li Dahu said with a smile, very excited.

"Well, yes, the brain spins quite fast, and he's tall, take it out, and you can bluff people without using your hands! Okay, it's just the two of them. Xiao Yao smiled with satisfaction.

"Xie Gongzi supports, our two brothers will definitely do their best to protect Gongzi, and will never let anyone hurt Gongzi in the slightest!" The two brothers said in unison.

The two brothers changed into civilian clothes, brought weapons, and escorted Xiao Yao back to Jinling City.

"Big Tiger, where are you two brothers from? How old are you and who else is in the family? Xiao Yao asked.

"Hui Gongzi, we are from Xunyang County, Jiangzhou, 20 years old this year, our two brothers are orphans, the soldiers are in chaos, in order to fill their stomachs to join the army, previously when Xunyang County guards, and then was fortunate to be selected to enter the guard to receive personal training from the tall people, but also at that time I listened to Gongzi's lectures, knew Gongzi's voice, and was later transferred to Jinling to be the guard of the general firm!" The dragon replied.

"Would it be a pity to leave the guards, no longer be a soldier, and come here to be a guard of a trading house?" Xiao Yao asked again.

"Of course not, it's much easier here than in the guards, we patrol near the workshop every day, and we haven't encountered any bad guys, Jinling is at the foot of the Son of Heaven, no one is messing around, and the ancestral shopkeeper is good to us, but we haven't slackened, or train hard every day according to the teachings of the tall people!" Dalong laughed.

Xiao Yao doesn't have the young master's frame at all, he talks and laughs with them along the way, and the big tiger is also very good at observing words and feelings, always following Xiao Yao's topic, picking good words and patting Xiao Yao's ass.

And Erhu was a little shy, not much to say, but very cautious, carefully observing the surrounding situation all the way.

Back at Xiao Mansion, Xiao Moke and Xiao Wuhua didn't say anything about Xiao Yao bringing back two personal guards, after all, Zu Yuan and Xiao Yao had a close relationship, and it was normal to send two bodyguards to him.

And Xiao Shilian is very jealous in his heart, he is a dignified son of the Xiao family, and now he has no personal guards, and you are a righteous son, now you can go out with a hug!
