I'm a useless prince, so what if I know a little bit of chemistry?

The Wang family mansion is located in an inconspicuous alley in the capital.

This alley looks like an alley where ordinary people live.

In the alley, several children were playing together. When they saw Wang Chengen and Nian Gui walking towards them in court robes, they were not afraid.

"Uncle Wang, have you left court?" A little girl with two ponytails and holding a candied haws in her hands greeted Wang Chengen happily when she saw him.

"Hello, Uncle Wang, and hello to this uncle as well." Several other boys also stood up and greeted them respectfully.

"Hello, have you eaten? Why don't you come to my house for dinner?" Wang Chengen asked with a smile.

"We've eaten. Let's go to Uncle Wang's house for dinner another day." A little boy said to Wang Chengen with a naive smile.

"Uncle Wang, do you eat candied haws?"

The little girl asked, holding up the candied haws.

Wang Chengen smiled and waved his hand, saying, "Uncle won't eat it, please be careful and don't get hurt."

"Okay." The little girl responded.

"Uncle, let's go."

The children greeted each other and left singing nursery rhymes.

Nian Gui smiled and praised: "It is said that you, Wang Chengen, are an honest official and a parent official of the people. This is indeed true. I really admire you."

Wang Chengen waved his hand and said, "We are all doing things for the people. There is no need to put on airs. It is good enough to do something practical for the people."

The two entered the Wang family mansion, which was different from the mansions of all officials in the capital.

The rest of the mansions, including those of the nobles, all had relatively large courtyards, and some of the front and back yards were large enough to accommodate hundreds of people.

Especially the gate, it should be as grand and majestic as the forbidden gate of the imperial palace.

But the Wang family was different. The front was small and could only accommodate three people side by side. Moreover, on the plaque of the Wang family, there was no Wang family or Prime Minister's Mansion written on it, but two big characters were written: For the People.

Moreover, the gate was not painted vermilion like the gates of other people's mansions, but was painted light blue.

The color is exactly the same as Wang Chengen’s official uniform.

Nian Gui was a little curious. After all, the official uniforms were all red, so why did the Wang family wear blue? So he asked, "Prime Minister Wang, why does Prime Minister Wang love blue so much? Not only are the official robes blue, but even the gates are blue?"

Wang Chengen laughed and explained to Nian Gui, "I also asked my father this question when I was young. General, can you guess how my father answered?"

Nian Gui waved his hand and said, "As for what Lord Wang said, I am just a warrior and I really don't know. I would like to ask Prime Minister Wang to explain it to me."

Wang Chengen's face was full of admiration, and he said to Nian Gui: "My father told me at that time that the red official robes were stained with the blood of the people, so he wanted to wear blue to plead for the people."

Hearing this, Nian Gui stood in awe.

The Wang family are all good officials who serve the people. They always consider the people first when doing anything. After listening to Wang Chengen's words, Nian Gui had even more respect for the Wang family.

"I never thought that Lord Wang would care so much about the people of the world. I really admire you. No wonder the Wang family is full of loyal heroes."

Wang Chengen smiled ashamedly, waved his hand, and said: "My father has done things uprightly and devoted his life to the country and the people, but I still cannot bear the praise of the general."

As they were talking, the two entered the Wang family mansion.

The Wang family mansion is not big, with only two courtyards in the front and back.

There are four rooms in the front yard and a vegetable patch at the door where many vegetables are planted. An old servant is watering the vegetables.

"My father and I grow these vegetables in our spare time. If we don't have time to take care of them, we will have servants take care of them." Wang Chengen said.

The two did not go to the living room.

Wang Chengen took Nian Gui all the way into the study.

Before entering the study, Wang Chengen carefully checked the surroundings and made sure that there was no one there before closing the study door.

"Prime Minister Wang, I wonder why you brought me here?"

Seeing that Wang Chengen was acting mysteriously, Nian Gui began to ask.

Wang Chengen sighed, looked at Nian Gui and said, "Hey, Nian Gui, General Nian, can't you see that His Majesty is going to take action against the Nian family?"

Nian Gui was stunned. He naturally knew what Emperor Liang meant, but he was not clear about Wang Chengen's position, so he pretended to be deaf and dumb.

"Huh? Your Majesty wants to attack my Nian family? How is that possible? I, Nian Gui, have made outstanding military achievements. Why would Your Majesty treat me like this?" Nian Gui asked with a puzzled look on his face.

"General Nian, are you really stupid or are you just pretending to be stupid? His Majesty asked you to recruit troops and go to the frontier on your own. Isn't it to consume the strength of the Nian family?"

Wang Chengen was a little anxious.

"So Prime Minister Wang, do you mean that we should stop fighting the three kingdoms outside the Great Wall?" Nian Gui looked at Wang Chengen and said coldly.

Wang Chengen waved his hand and replied: "The Xiongnu must be fought, and we must use General Nian's method."

Nian Gui said nothing and just looked at Wang Chengen.

Wang Chengen continued, "As for whether to consume the Nian family or not, it has nothing to do with me. I just want to ask General Nian one thing."

"What's the matter?"

"What does the general think of the second prince Lin Rui?" Wang Chengen stared at Nian Gui.

"Lin Rui? Haha, this general has not been in the court for a long time and does not know about this matter. Prime Minister Wang, goodbye." Nian Gui waved his hand and turned to leave.

Nian Gui had just taken a few steps when he suddenly turned around and said to Wang Chengen, "Prime Minister Wang, don't be in a hurry to appoint a crown prince. It's better to see if Fan'er can do the job first."

After saying this, Nian Gui left the palace.

"Are you a little anxious?" Wang Chengen murmured.

Wang Chengen was not worried that this matter would put his family in dire straits.

Wang Chengen only wanted to support a wise monarch to ascend the throne. So what if his Wang family died out?

"Son, you are indeed a little anxious."

Lord Wang came out, his body hunched.

"Father." Wang Chengen called out and quickly supported Lord Wang.

"Your Majesty is in good health now. You should devote yourself to serving the country and the people. Why bother thinking about the crown prince?" Lord Wang said slowly.

"But father, without the crown prince, the court will be unstable," Wang Chengen replied.

Wang Ge Lao sighed and looked at Wang Chengen: "Son, how could I not know what you said? However, the situation is chaotic now, so it is better for my Wang family not to interfere in these matters."

Wang Chengen nodded and stopped disobeying his father.

"The arrogance of the Huns must be put down." Wang Ge Lao looked into the distance, and his turbid eyes became clearer.

"Yes, with the eldest prince's stirrups and saddle, the Huns are probably in great danger now." Wang Chengen echoed.

"I'm afraid the Huns will launch a desperate counterattack." Lord Wang sighed.

……

Inside the palace.

"Your Majesty, these are the eldest prince's itineraries, all reported by the Embroidered Uniform Guard." Hailong said, holding a stack of papers.

"Oh? I want to see how Fan'er is doing outside."

Emperor Liang took the papers from Hailong and read them one by one.
