Surprise! The Crown Princess drives a mecha into the battlefield

"Meng boy, why are you here? Where is the boy from the Ouyang family?" asked Duke Gu.

When Meng Yi heard this, his face immediately drooped.

Si Yuan saw Meng Yi's expression and asked hurriedly, "What happened in the North?"

Meng Yi took a deep breath and spoke slowly, "Some time ago, a caravan from Fengling State passed through the northern border and suddenly developed a high fever and persistent cough. Many soldiers were also infected. Military Advisor Ouyang is working hard in the city to control the spread of the disease. But..."

After hearing this, Duke Gu and Si Yuan's expressions became solemn.

"Medicinal materials are in short supply now. Military doctors have rushed into the city, but they are helpless." Meng Yi told the whole story of the situation in the northern border.

High fever, persistent cough, and contagious? Mu Wanwan listened from the side and thought these symptoms were most likely plague.

This disease was incurable in ancient times, but she had not seen the patient and could not easily make a judgment.

"Husband, I will let you and elder brother go to the northern border first, and you and grandpa will leave later." Mu Wanwan wanted to drive there faster so that she could get more information about the situation.

"Meng Yi, send a team of people to the City Lord's Mansion to assist Prime Minister Mu in guarding Tianque City. You will go to the northern border with us." Si Yuan immediately gave the order.

Meng Yi obeyed, feeling curious about Si Yuan's order. Just now, the woman had called the general "husband," and the general hadn't objected. It seemed his loyalty had paid off. But why was Prime Minister Mu in Tianque City?

Leaving Ying Er and the others to escort Duke Gu and others, Mu Wanwan and Si Yuan set off with Meng Yi and Mu Yuheng.

The four of them rode on fast horses and stopped on a small path outside Tianque City.

"Why did the general stop?" Meng Yi was very curious. Didn't he say he was going to the northern border?

"Deputy General Meng, just be happy. I'll help you broaden your horizons." Mu Yuheng patted Meng Yi's shoulder and said with a wicked smile.

Meng Yi was confused. He had seen this young master from the Prime Minister's Mansion before, so why was he so unstable now?

Meng Yi was still in a daze when he was suddenly startled by the scene in front of him.

Mu Wanwan just waved her hand and the four horses disappeared.

"General...where is her...horse?" Meng Yi was so frightened that he couldn't speak clearly.

"Shut up, you're so ignorant." Mu Yuheng saw Meng Yi pointing at his sister and quickly scolded him.

Meng Yi was so shocked that he shut his mouth.

Mu Wanwan smiled and took out another off-road vehicle.

Meng Yi looked at the large iron box that suddenly appeared before him, with four wheels underneath. Is this some new type of warhorse? But the horses just disappeared.

"Get in the car." Si Yuan sat in the driver's seat and asked everyone to get in.

Mu Yuheng opened the car door and jumped in first, while Meng Yi was still standing there in a daze.

"Get in the car, why are you still standing there?" Seeing Meng Yi still standing there in a daze, Mu Yuheng opened the car door next to him and pulled Meng Yi in to sit.

Meng Yi sat in the car, feeling uneasy. The seat inside was so comfortable.

Si Yuan started the car and sped along the official road towards the northern border.

Meng Yi gripped the handrail nervously. What he saw was beyond his comprehension. How could his general be driving such a strange carriage, and at such an astonishing speed?

He stole a glance at Mu Wanwan. Just now, he thought the general's wife was some kind of monster, but now it seemed that his general had married a fairy. She could easily conjure up such treasures.

Meng Yi was shocked and suspicious, and suddenly felt dizzy and a little nauseous.

Mu Yuheng saw Meng Yi's condition and quickly sat next to him and ordered.

"Wanwan, Lieutenant General Meng seems to be carsick." Mu Yuheng said to Mu Wanwan in the front row.

Mu Wanwan turned around and saw Meng Yi's expression. She quickly took out a paper bag and handed it to Meng Yi, "Hey, don't vomit in my car."

Meng Yi took the paper bag, suppressed the discomfort in his stomach, and smiled embarrassedly at Mu Wanwan.

Mu Wanwan took out another motion sickness pill and gave it to him.

Meng Yi took the pill and quickly swallowed it. Calm returned to the car, and Meng Yi's complexion gradually improved.

After speeding all the way, as the sky gradually darkened, everyone arrived at the Northern Border City.

Mu Wanwan put the car into the space. Meng Yi was still shocked when he saw the big iron car suddenly disappear.

"Let's go, let's go find Mo Yu first." Mo Yu was the name of Ouyang Military Advisor. Si Yuan led a few people into the city gate.

The soldiers defending the city were very excited to see Si Yuan. Their general had returned. They all saluted him, their faces full of respect.

Mu Wanwan was proud to see the respect these soldiers showed to Si Yuan.

She knew that these soldiers' loyalty and admiration for Si Yuan was not because of his status as the crown prince, but was earned by Si Yuan with his life and blood on the battlefield.

The group rushed to Ouyang Moyu's residence. When the gatekeeper saw Si Yuan, he quickly led them inside.

"You still remember to come back? If you don't come back, I will bring people back to kill you." When Ouyang Moyu saw Si Yuan, he couldn't help but joked, but his eyes were full of concern.

"Ouyang Moyu, you only see your general. Can't you see this young master?" Mu Yuheng joked.
