After Qin Xuezhen limped back, she hid in her room and cursed the imperial concubine.

"This vixen is so abominable and hateful! How dare she punish me like this? One day I will make her kneel before me and dig out her kneecaps."

Qin Xue was so angry that she went crazy and cursed. It was only after a long time that the system spoke.

[Remind the host, General Kangnan will be back soon, you still have a mission to complete.]

"I get it! What good are you doing besides urging me on all the time? Aren't you a luck system? Can't you control NPCs? Why didn't you teach that concubine a lesson? Why didn't you let them let me go?"

[Host, the system will not manipulate NPCs casually. Doing so would consume a great deal of my energy. So far, you've completed very few missions. It's already very difficult for me to maintain enough energy to protect and assist you.]

Qin Xuezhen couldn't hear anything at all now. She only knew that her mind was full of tasks.

"Shut up, you piece of shit! I'm going to complete my mission now, so get lost."

Qin Xue felt extremely aggrieved. After applying medicine to herself and being able to walk barely, she hurriedly opened the mechanism in the study and entered the secret room.

However, what she was looking for had already been replaced by someone else, and the account book she had finally found was a fake.

But Qin Xuezhen didn't know, and because the system in her body did not conduct any detection, she allowed this stupid woman to take the fake account book back.

After Mu Chan returned to the imperial concubine, he hurriedly took out the real account book.

"Good boy, you really didn't bring shame to your father!"

As General Mu spoke, he took the account book and his face changed after looking at it.

Seeing her father's bad face, the imperial concubine leaned over to take a look. After seeing the number clearly at a glance, the imperial concubine's face changed.

"Oh my god! The iron ore supplied to the imperial court in recent years is less than 30% of the output of these two mines. If all the remaining iron ore were made into weapons and even equipped with soldiers..."

The imperial concubine did not finish her words, but Mu Chan couldn't help but continue.

"If we form a cavalry unit, this place is very close to our imperial city. If any foreign warriors appear, this unit will be able to attack Huangdu with lightning speed!"

Now they finally realized the horror. The eldest prince hurried back in the evening and was even more shocked after reading the account book.

"It seems that this Kangnan really wants to rebel. I will send a letter of divorce immediately and ask the emperor to send an army to suppress him."

As he was speaking, the eldest prince stood up and walked to the desk to start writing, but Mu Chan reminded him in time.

"Your Highness, you should show off your abilities now, but you should also write another memorial praising Kang Nan and explaining that there is nothing wrong with him."

The eldest prince understood that Mu Chan wanted to paralyze Kang Nan, so he nodded and wrote two letters. He asked his men to deliver one letter and gave the other letter to the Mu family's guards to deliver.

After everything was done, the eldest prince thought for a moment and put forward his own ideas.

"In my opinion, we should coordinate and support him instead of just waiting for our father to come and support us. We don't know where the iron ore is hidden, and we don't know if he is secretly cultivating manpower. Shouldn't we investigate as well?"

At this time, Mu Chan took a look at Yao Guangyue who was sleeping next to him and couldn't help but smile.

"We should indeed investigate. That maid named Xiao Cui seems to know a lot. Your Highness, why don't we split up and see who finds the hiding place of the iron ore first?"

As soon as he heard about the competition, the eldest prince's desire to win was aroused.

"Mu Chan, since you said so, then I will take it seriously. If I win, you have to take care of my marriage!"

These words made two turns before reaching the ears of General Mu, who suddenly widened his eyes as wide as an ox.

"Your Highness Prince Yu, what do you mean? Are you planning to marry my second son? If I don't agree to the marriage, His Majesty won't agree either!"

The word "I don't agree" scared Yao Guangyue awake. She was sleeping just now, but her mind was full of marriage and disagreement. What was going on?

[Hey, what's going on? I finally got some sleep, and now you're disagreeing with something about marriage? Who's getting married? Who's disagreeing?!]

The eldest prince and Mu Chan were immediately panicked, because they were not talking about the marriage of these two people!

But some time ago, Mu Chan said that there was a knowledgeable cousin in the side branch of the Mu family. Moreover, this girl was in her prime, smart and beautiful.

The eldest prince immediately had an idea, but Mu Chan pretended to be serious and refused to act as a middleman no matter what.

So the eldest prince has been very anxious recently!

"Oh, General Mu, you misunderstood me. I'm not as good as Long Yang!"

Mu Chan was also anxious. Just as he was about to speak, he was blocked by his father.

"Oh, Dad! I..."

"Just shut up! If you say anything that displeases me, I'll lock you up when I get home!"

The old general over here was busy chattering, and Yao Guangyue over there was almost about to become a couple.

[The system just said who was going to get married? Was it the eldest prince and my uncle?]

[Is that so?]

Oh my god, what kind of taboo literature is this? It's over, it's over, my heart is not beating.

This startled the system again, and it quickly called out to its host.

[Host, please calm down and don't get so excited. If you suffer a cardiac arrest, my mission will end right there!]

The whole room was filled with noise. General Mu raised the cane that had made three crown princes cry, and beat the eldest prince out of the room.

"Oh! General Mu, you really misunderstood. The one I'm seeking to marry is the daughter of a branch of your Mu family, not Mu Chan!"

As soon as he finished speaking, General Mu's crutch landed steadily on the eldest prince's buttocks.

The eldest prince's face was covered with tears at this moment. He never dared to make fun of his father again, who was beaten to tears by General Mu's crutch.

What on earth is this crutch made of? Why is it so heavy? It seemed to have hit my injured leg just now.

After learning that the eldest prince was not coveting his son, General Mu put down his crutches.

Thinking that he had wronged the eldest prince, he asked a doctor to treat his injuries.

After the doctor arrived, he looked at the eldest prince's injured leg and fell into deep thought.

"It's strange. This meridian was slightly deviated, so the injury took a long time to heal. How come it's coming back now? Was it hit by something?"

As soon as these words were spoken, everyone present twitched their lips.

At this time, there was also movement coming from Yaoguangyue.

[Ding, congratulations to the host for reaching a 44% plot collapse value, 2% of which comes from the eldest prince's leg injury being healed.]
