This is the ninth time the system has done this. It should be super awesome.

After several days of hard work, ten sets of fireworks were finally completed on Jiang Xinxin's mother's birthday. During this period, Grandpa Jiang Tianqi came once with his two sons. All three of them were very excited. Why?

Because the old man didn't take the bottle of pill seriously, he hadn't paid attention to it at first. If Jiang Xinxin hadn't come over and mentioned it, he would have forgotten about it. However, after taking it and experiencing the cleansing effect of the marrow cleansing pill, he was no longer calm. He called his two sons and gave each of them one pill. After experiencing the effect of the pill, the three old men saw the horror in each other's eyes.

Then they hurried to find Ling Feng. After learning about the efficacy of the pill, they looked at Ling Feng eagerly, full of desire. Ling Feng was helpless. Apart from the one he gave to Jiang Xinxin, the three he ate and the three he gave to the old man, he also gave the rest to the old man and let him distribute it himself. He didn't want to worry about it.

Put the finished fireworks away. These past few days, I have been making fireworks and practicing. I haven’t had a good bath. I have to take a good bath because I have to attend a birthday party tomorrow. Although only family members are there, it will still be very lively.

I heard from Xinxin that someone will come to the eldest lady's house. The eldest lady is the daughter of the current prime minister, and the two families are also old friends. The person who comes is probably of high status. Jiang Xinxin's second wife is the daughter of another great general in the kingdom. I don't know if there will be anyone from the palace, but it doesn't matter if they don't come. You will see it anyway. I don't believe you won't come out to see it.

The birthday party arrived as scheduled, with lights and decorations, people coming and going, and the family was happily in the yard. Someone came from the prime minister's family, Jiang Xinxin's uncle, with a gift box. Someone also came from the second mother's family. After all, they were both from the military, and the two old people were comrades in life and death, so it would be unreasonable if no one came.

They came up to give gifts one by one. As it was a family banquet, there was no comparison and the atmosphere was very harmonious. After everyone had given their gifts, Ling Feng stepped forward and bowed to the birthday boy.

"Auntie, I don't have anything to give you, but I can give you a visual feast."

Everyone was confused. The two words were understandable separately, so why were they so confusing when put together?

Regardless of everyone's curiosity, Ling Feng took out the fireworks he had prepared earlier. There was no beautiful packaging, only paper shells. Although everyone wanted to stop Ling Feng and ask him about it, they waited patiently as they saw that he was busy moving things.

Ling Feng had an idea and did not set off the fireworks on the ground. He was still thinking about the sign-in task, so he moved all the fireworks to the roof, under the pretext that the roof allowed them to be set off higher. In fact, he just wanted to wait until the emperor summoned him to the palace to set off the fireworks so that he could go to the sign-in location naturally. It would save time and effort.

He took out a fire starter, lit the fuse and stepped back two steps, becoming excited. You know, fireworks have not been allowed on Blue Star in recent years, and he hasn't seen fireworks for a long time.

With a loud bang, everyone in the courtyard was startled. Before they could react, they were attracted by the beautiful fireworks that followed. From afar, they could see a bright flower of light blooming in the dark night sky. As the fireworks bloomed one by one, the entire imperial city slowly quieted down. Everyone stopped what they were doing and quietly appreciated this beautiful thing. Even some assassins who were secretly assassinating stopped their movements of aiming at the target's heart.

There is no such thing as fireworks in this world. After Ling Feng learned this from Jiang Xinxin, he was secretly delighted. You know, the first time is the most shocking, and the visual enjoyment of being conquered by the dazzling fireworks is incomparable. Looking down at the expressions of the crowd, Ling Feng was very satisfied and secretly said it was settled.

After setting off one, he would light another. It took him about 10 minutes to finish setting off all the fireworks he had made in the past few days. After that, Ling Feng jumped down. The paper shell was still a little hot, so he left it to the servants to clean up.

When I came to the crowd, I saw that they were still staring at the night sky in a daze. Each of them had a smile on their face, even the old man was no exception. That was their yearning for beautiful things.

"Feng boy, what, what is this thing? It's so beautiful!" The first one to come back to his senses was the old man. He had a high level of cultivation and great concentration.

The old man's words also brought the others back to their senses. They looked at Ling Feng eagerly, which made Ling Feng's scalp numb. He quickly explained: "Haha, everyone, this is called fireworks. We have them during festivals and banquets. I heard Xinxin say that there are none here, so I made some to show you."

"So pretty! This is the first time I've seen such beautiful flowers."

"Yes, it's really beautiful. I want to see it again. Do you have any more, boy?"

……

A group of people were chattering, but Ling Feng felt a little scared after hearing everyone's ideas. You know, making fireworks is very time-consuming and energy-consuming, and there are no tools or materials here, and you have to make the ingredients yourself. It is very troublesome to do it once. If it were not for the sign-in task, he would not do it. However, he can teach the manufacturing method to the old man, and he can also develop it. It may even be a very profitable industry.

A group of people surrounded Ling Feng and asked him questions, which made Ling Feng feel a little overwhelmed.

"It can be done, but it's rather troublesome. I will teach the method to grandpa later and let him learn it from someone special. It can be developed into a business. Maybe he can even make a lot of money. Hahaha." There was no other way but to shift the blame. I'm sorry, grandpa.

When the prime minister's son and the second aunt's family heard this, they actually turned their heads to look at the old man. Although they were in politics and the military, they could also see great business opportunities in this. If you don't make money, you're a bastard. The two of them directly took the old man away and insisted on joining the group. Everyone should make money. We can't let your family get away with it. After all, we are relatives.

The big guys all went to discuss joining the gang, and the remaining group of women no longer paid attention to Ling Feng. They were all talking about the fireworks, and each of them looked like they hadn't seen enough.

People in the whole city all looked as if they were still unsatisfied. They hadn't seen enough and wanted more. However, some people were in a more miserable situation. All the assassins who had attempted assassination tonight were killed in counterattack. This made the assassin world very painful, and a large number of them died directly.

Ling Feng didn't care about these things at all. He was now looking forward to the reaction of the palace, and fell asleep with difficulty in a nervous mood. The next day, Jiang Xinxin brought him a piece of news that made him happy.

Early this morning, someone came to the palace, discussed with the old marshal, and then left.

The Empress Dowager's 70th birthday will be coming soon. After learning from what the chief of the Guardian Clan had noticed last night that the fireworks were set off by the old Marshal's family, the Emperor also wanted to give his mother such a beautiful performance on her birthday to make her happy. So he sent someone to the Marshal's house early in the morning.

Ling Feng was so happy, it was done, the next step was to make the fireworks. He happily ran to the old man and asked him to arrange suitable and trustworthy people to come and learn how to make fireworks from him.

"Haha, the sign-in reward is waiting for me."
