Yu Zhigan suddenly felt that this world needed to be saved by himself.

For example, the legendary formula for multiplication of ninety-nine was found in the Warring States Period, but it was not available in Yu Tang, and the title of inventor was hung on Yu Zhigan's head.

The same seems to be true for fireworks. Li Ting didn't even understand this thing, so he definitely needed to take action himself.

Strictly speaking, fireworks are not difficult. Just send the fireworks to the sky. The light generated after the fireworks explode depends on metal powder and black gunpowder to send the fireworks into the air, and then explode in the air. It is so simple.

"Well, that's it, have you ever tried to let the firecrackers explode in the air and add something so you can see clearly at night!"

Yu Zhigan raised a little, and when Li Ting heard it, his eyes lit up. He instantly understood what Yu Zhigan meant, and said shyly: "Your Highness, Caomin has this idea, but because studying firecrackers requires a lot of money, Caomin, Caomin!"

"I'll give you one thousand taels. I'll make fireworks for me before the New Year. There's no problem!"

Yu Zhigan stared at Li Ting and asked.

Li Qi heard the light in front of him, and then he panicked: "Your Highness, this, this..."

"I'm optimistic about you, come on, if you can't study it, I'll study how to get you to heaven!"

After saying that, Yu Zhigan left the side hall directly, leaving Li Ting alone looking at Yu Zhigan's back with a confused look on his face. It seemed that he might have developed.

Yes, Li Ting felt that he might have developed. He was an ordinary firecracker craftsman who made money by making firecrackers. Now he seemed to have suddenly hugged the prince's thigh. If nothing unexpected happens, he seems to be really...

Soon a housekeeper named Chen Wansan took Li Ting to a dilapidated side hall in the backyard of the East Palace: "This is the place you will study in the future. If you need anything, everyone will hurry up and say it. Your Highness the Crown Prince said that if the mission cannot be completed before the New Year!"

When Chen Wansan said this, he was already ready to go. As the butler of the Eastern Palace, Chen Wansan was hostile to all those who wanted to take money from him. For example, Li Ting now had no ability, but he actually fooled His Royal Highness the Crown Prince for 1,000 taels of silver.

"Butler Shen, I need some equipment, but they are all in my house. Can I get it? I also need it..."

After hearing this, Chen Wansan nodded slowly. This guy is not bad. He knows how to use the things he used to, but he doesn't want that guy Zhu Youxiao to have new everything. The most powerful person in the entire East Palace is this guy, who spends a lot of money on average a day.

Now, Zhu Youxiao has developed various high-end, elegant and high-end brands such as pear blossom tricycles, golden nanmu bicycles, etc., and is also preparing to price the price on it. This is more like a carriage, but it seems that no car has been sold yet.

Walking out of Li Ting's research area, Chen Wansan looked at the sky. It seems that there is still a long way to go to the East Palace to save money. He needs to come slowly and little by little. A few days ago, he just saved some money from the perfume workshop, but now another guy who doesn't know if it's a big money-using person has come.

In the East Palace School, a big red-faced man, Guan Erye, looked at a white-robed general in front of him with a smile: "General Chen, a grass-rooted Guan Yu, have seen General Chen!"

Chen Qingzhi glanced at Guan Yu, pinched Guan Yu's strong muscles with his hands, and nodded: "You are Guan Yu!"

"Yes, the people are willing to worship..."

"Well, I know, can I fight?"

After saying that, he threw a spear over. After looking at it for a while, Guan Yu pointed to the sabre not far away: "Which can I use?"

Yu Zhigan watched the scene of Guan Gong fighting Chen Qingzhi with relish. Both of them were famous generals in history, but it was obvious that Guan Yu had stronger combat effectiveness. After about twenty rounds, Chen Qingzhi collected his gun: "Yes, how about you join the left guard and become a primary school?"

"The grass-roots thanked General Chen!"

Guan Yu didn't feel anything. So what if he could beat the general? It would be good to have a small school. After all, he started with a horse archer before, huh? Why did he say that before?

After watching Guan Yu leave, Chen Qingzhi wiped the sweat from his forehead and walked to Yu Zhigan: "Your Highness the Prince!"

"How about it?"

"I am a general. I will lose within thirty moves. Where did the Prince find the talents?"

Chen Qingzhi had no private hiding, and he still recognized Guan Yu's strength very much.

"I tell you, if it was picked up by me in Higashi City, would you believe it?"

Yu Zhi spread his hands out. Whether Chen Qingzhi believed it or not, he must have believed it, because the truth is that, he just went out for a walk and met Hua Xiong, and then Hua Xiong and Guan Erye were hooking up...

"Your Highness, have good eyesight!"

After Chen Qingzhi finished speaking, he couldn't help but twitch the corners of his mouth. His position as the commander of the Eastern Palace Guard might be out of control. I know if His Royal Highness the Crown Prince will meet Zhang Yu and Liu Yu's guy next time he goes out...

"Okay, go and do it!"

Yu Zhigan arranged the book and was about to go to the kitchen to see how the cake he prepared was like. He had tried it twice before, and it seemed that the effect was pretty good.

However, when Yu Zhigan came to the kitchen, he discovered a problem. It seemed that his cake had been stolen.

In the Eastern Palace, he dared to steal Yu Zhi's things, he was nothing more than the crown princess, Diao Chan and Lao Ba. In addition, there was Jing Ke who was shameless and could not do what he could do if he caught him!

"The Crown Princess is losing weight recently!"

Yu Zhigan thought for a while, and after thinking for a while, he decided to check them one by one. If he couldn't find it, then there was only one possibility, that guy Jing Ke did it. Yes, it must be that guy!

It is easy to find the Crown Princess. She insists on exercising every day in an open space in the back garden, but now she loses weight and has started to slow down. However, it seems that her muscles are becoming stronger and stronger. However, overall, she has lost a lot and her whole body has improved a lot.

I saw that the Crown Princess was sitting on Bobby's dance now. Yu Zhigan had never known why the so-called Bobby's dance was called Bobby's dance? Because Bobby's dance like this? The image of a short Yodel man appeared in Yu Zhigan's mind...

"Your Highness!"

After seeing Yu Zhigan, the Crown Princess' eyes lit up and she immediately leaned over. Yu Zhigan walked over slowly: "No, I've lost a lot of weight recently!"

The Crown Princess looked at Yu Zhigan shyly: "Your Highness, you like it!"

Now the Crown Princess is still acceptable to Yu Zhigan. Forget it before, Yu Zhigan doesn't want to mention it, otherwise...

"I've been training here today?"

"Well, I've been practicing for a whole morning, and now I'm used to it. At the beginning..."

Yu Zhigan looked at the Crown Princess, not like he was lying, and there were no traces of white cream on the corners of his mouth. As for where the cream came from? This question may require more than 100,000 words to explore, so skip it directly...

If it is not the Crown Princess, then the suspect is Cheng Xiang now. Yu Zhigan had forgotten Cheng Xiang before. After Cheng Xiang entered the East Palace, this woman, has always been obedient to Yu Zhigan, but in essence, he can also be lawless in the East Palace!

When Yu Zhigan saw Cheng Xiang, Cheng Xiang was learning from Sun Erniang and Hu Sanniang. Yes, after this violent woman married into the East Palace, she became like a good girl. As long as Yu Zhigan appeared, she would show the shy side of a woman. If Yu Zhigan hadn't occasionally seen her sweeping her across the Thousand Army with a big axe in the East Palace schoolyard, she would have really believed it.

After carefully checking Cheng Xiang and confirming that there was no problem, Yu Zhigan narrowed his eyes and was getting closer and closer to the truth. Jing Ke's suspicion had risen from 20% to 80%, and 20% were Diao Chan and Xiao Ba.

However, Diao Chan is a good baby. She has been in the Eastern Palace for so long and has always been a good girl. She only occasionally plays with a shoulder-to-stop...

"Brother Yu, that white cake is so delicious, I want to eat a little more!"

Before Yu Zhigan found Diao Chan in a small yard, he heard Diao Chan's voice and immediately leaned over and listened carefully.

"Okay, I'll take you to the kitchen to eat a little secretly. Don't eat too much. This is made by my elder brother himself, and it seems to be of use!" Xiao Ba said in a low voice.

"Your Highness the Crown Prince is really talented. When I grow up, I will find a prince brother like me..."

Diao Chan said in a low voice, and Xiao Ba blushed when he heard this: "I am also very talented, I have invented a small bicycle for you!"

After saying that, he pushed the small bicycle in front of him hard. This thing was made by Lao Ba, roughly equivalent to the small scooter in later generations. It can be seen that Xiao Ba is also a very smart child.

After solving the case, there is no need to investigate. The two little guys admit that Diao Chan is the mastermind, but she dare not do it herself, while Xiao Ba is a bold guy.

Yu Zhigan walked out from behind the courtyard wall with a cold face. Xiaoba's face changed when he saw it, and then he protected Diao Chan behind him: "Brother, I want to eat!"

"..." Before he could say anything, the guy admitted it on his own initiative. Yu Zhigan couldn't help but shake his head: "I know it's what you want to eat. If you want to eat in the future, can you not make it for you?"

Xiao Ba looked at Yu Zhigan with a skeptical look, his eyes full of distrust, while Yu Zhigan looked at Xiao Ba, his eyes full of three words. You have to believe me, it’s not right, five words.

After thinking a little, Yu Zhigan had a general plan. It seemed that he really lacked two people to try it. As for why he didn't try it by himself, haha, Yu Zhigan felt that his stomach still wanted to live two more years.

"Let's go and take you to have a cake!"

"That's called cake?"

"Yes!"

Yu Zhigan, Diao Chan, the left hand, and Xiao Ba, was shaking towards the kitchen behind the East Palace.

In the kitchen, Yu Zhigan looked at Diao Chan eating the cake in big mouthfuls, and couldn't help but wonder, "I am really a genius?" The things I made are very delicious.

"Is it tasty?"

Yu Zhigan looked at Diao Chan with some curiosity, and Diao Chan nodded: "Sweet, delicious!"

Yu Zhigan cut a small piece and tasted it. It felt very sweet when I got it in my mouth, and it was very greasy. Yu Zhigan felt that it was because he had put a little too much oil. The taste was a bit weird and I couldn't help but think about it and prepared a new one.

Yu Zhigan was a bit by bit by himself. First of all, the cream and butter must have milk and butter. At the beginning, Yu Zhigan used oil and milk to mix it together. The taste was that Yu Zhigan took a bite and threw it on the ground. Neiha and Satsuma did not bring it to eat.

Later, Yu Zhigan added sugar to it, and the taste was neutralized. It felt okay, but it seemed that there was still something missing. Yu Zhigan thought about it for a long time but couldn't figure it out because the other creams were very sticky, and the cream he made himself was smoother than Dove.

"Slightly sticky stuff!"

Yu Zhigan narrowed his eyes and thought, and suddenly his eyes lit up. He knew about something in his heart, egg white, and patted his head hard. He was really stupid. He needed eggs to make cakes, and he was only now remembered.

After thinking it through, Yu Zhigan quickly started making his own cream.

The process of making the cream is very easy, but the ratio may have been wrong. Yu Zhigan just tried it out and then gave the remaining items to Diao Chan and Xiaoba. Yu Zhigan kept experimenting and failures all afternoon.

"Xiao Ba, come and have another taste and see how it tastes?"

Xiao Ba looked at the cream in front of him, swallowed hard, and shook his head firmly: "Brother, I will never dare to steal your food again!"

Xiao Ba was almost crying, it was so scary. His elder brother was so scary. He just stole a cake and actually fed him all afternoon. Although the taste was good, he was still a child after eating for an afternoon...

"Diao Chan, come and taste it?"

Yu Zhigan looked at Xiao Ba, as if he really couldn't eat it, and couldn't help but look at Diao Chan.

At this time, Diao Chan's belly was already bulging. When she saw Yu Zhigan coming with butter, she immediately waved her hand: "Your Highness, Diao Chan can't eat it anymore!"

Yu Zhigan looked at Diao Chan and Xiao Ba again, feeling that these two little guys might not steal their own food in the future. He nodded with satisfaction, then took a bite and quickly poured out the basin of cream.

The taste was even more wrong. Yu Zhigan wondered if he had added the egg white himself.

In two days, when Yu Zhigan met anyone, he said one thing: "Come here to taste it for me!"

Now, when everyone saw Yu Zhi doing it, they would turn around and leave without saying a word. It was so terrible, it was so terrible. As long as they followed the prince to try it, no one was released without eating, and their stomachs were about to explode.
Chapter completed!
