Surprise! The Crown Princess drives a mecha into the battlefield

Mu Wanwan studied the map carefully and found that it was no different from the modern map in her previous life.

The green area shows the surviving humans, a small number of whom are mainly concentrated in China. The red area represents the zombies' active areas, which are quite widespread.

Mu Wanwan chose Jing City, where she lived in her previous life, as the landing site. It was a densely populated big city. Although it became depressed in the apocalypse, there were relatively many survivors.

After clicking confirm, the system prompt sounded. Mu Wanwan purchased a bunch of supplies from the modern interface, including food, water, medical supplies and simple self-defense tools, and asked No. 02 to put the supplies into the trading machine.

When I clicked on the end-of-the-world page again, the homepage was still empty, with only my own store information.

........................................................

On the second day, Mu Wanwan and Si Yuan found Yang Heling with the signal base station equipment they had purchased last night.

Ever since Yang Heling got those engineering books from Mu Wanwan, he has been studying the books with his former students.

"Lord Yang, the road construction project in the northern border is progressing so quickly thanks to you." Si Yuan brought Mu Wanwan to Yang Heling's mansion.

Upon hearing this, Yang Heling waved his hand and said, "It is all thanks to the relevant books and materials given by Madam. I am just helping to supervise." Yang Heling knew that if Mu Wanwan had not provided the materials, it would be impossible to make those materials with the current technology.

He was also sincerely grateful to Mu Wanwan for having the opportunity to be exposed to new engineering knowledge at his age, and his passion was rekindled.

"I came here today to ask Lord Yang for help in installing this item." Mu Wanwan handed the relevant information about the signal base station to Yang Heling.

Yang Heling took the information and studied it carefully, his eyes immediately revealing a strong interest in such novel things.

Yang Heling raised his head, a glint of excitement flashing in his eyes, "Madam, with this item, can we really transmit sound over a thousand miles?"

Mu Wanwan nodded, took out the phone from the space, and then explained: "As long as the signal coverage range, this thing can achieve long-distance communication."

A hint of curiosity flashed in Yang Heling's eyes, and Mu Wanwan did not explain too much. This product that spanned thousands of years could not be understood by the ancients through books and oral narration.

Mu Wanwan only handed over the matter of the signal base station to Yang Heling and asked Yang Heling to follow the installation instructions.

Mu Wanwan took out the base station equipment she had purchased from the space and left with Si Yuan.

"I miss my mother and Chaochao a little bit." On the way back, Mu Wanwan thought that she wanted to build a base station just to contact her mother and others. She had been in the Northern Territory for so long, but she had not contacted them yet.

Upon hearing this, Si Yuan's brows flashed with tenderness, and he softly comforted her, "Wanwan, let's go back to Tianque City to visit them, and bring Big Brother along."

Mu Wanwan nodded, and the two of them went to the military camp to call Mu Yuheng.

Mu Yuheng has been busy training the musketeers these days. When the two arrived at the training ground, Mu Yuheng was explaining the operating principles of the rifle to Si Yuchen.

When Mu Yuheng saw Mu Wanwan and Si Yuan, he immediately put down his rifle and walked over quickly. "Sister, Si Yuan, why are you here?"

Si Yuchen saw the two men put down their rifles and walked towards them.

"Brother, we plan to go back to Tianque City to visit dad and the others, and we want you to go back with us!" Mu Wanwan said.

"Okay, I'll let Mo Yu take over." After Mu Yuheng said that, he walked towards Ouyang Mo Yu's tent.

"Wanwan, I will go with you to Tianque City. I haven't seen the Prime Minister for a long time. This time I will go to visit the in-laws." After hearing what Mu Wanwan said, Si Yuchen expressed his willingness to go together.

Si Yuchen asked Xiao Yi to prepare some gifts. Xiao Yi was competing with Ying Er in shooting. When he heard Si Yuchen's instructions, he immediately returned home to prepare.

When everyone was ready, Mu Wanwan took out the G-Class from the space and asked everyone to get in.

"Your Highness, would you like me to go with you?" When Xiao Yi saw the big iron box that Mu Wanwan took out and saw that His Highness had no intention of taking him with him, he couldn't wait to speak.

I also want to try this big iron box. Your Highness, please call me along.

"Just stay in the northern border and wait for Xiao Er and the others to come back and reunite." Si Yuchen said after a moment of thought.

Although Xiao Yi was somewhat disappointed that he could not travel with His Highness, he knew that Xiao Er and the others would need someone to pick them up when they returned to the northern border.

Si Yuan stepped on the accelerator and the car sped away, raising a cloud of dust.

Xiao Yi looked at the big iron box that was getting farther and farther away from him in shock. What kind of magical weapon was this? It was so fast.

Ying Er walked over and saw Xiao Yi's expression, and couldn't help shaking his head. As expected, whenever his mistress took out something, he would see other people's expressions like bumpkins.

"Yuan'er, you can actually drive this strange car?" Si Yuchen had seen helicopters, but he had never seen a carriage that could run so fast on the ground. Now seeing Si Yuan steadily controlling the car, he couldn't help but feel amazed.

"Father, if you want to learn, you can go to the driving school in the north. I will give you one then." Mu Wanwan, who was standing aside, saw Si Yuchen's enthusiastic look and said with a smile.

Yesterday, when Ouyang Moyu was talking to Si Yuan, he mentioned the completion of the driving school.

With the participation of the Northern Border Army, the road construction project between Beijing City and Tianque City has been completed for the most part.

The vehicle was driving on the smooth asphalt road, everyone was in a good mood, and the scenery outside the window was quickly receding like a painting.

"This road is really easy to drive on. Compared to the bumpy road before, it is much more comfortable now." Mu Yuheng looked out the window and couldn't help but sigh.

The vehicle quickly drove to the outside of Tianque City, and Mu Wanwan put the vehicle into the space.

Several people entered Tianque City and walked towards the City Lord's Mansion.

"Master, Madam. The young master and the young lady's husband are back." As soon as Butler Zhou saw these people appear, he immediately took them into the mansion.

"Uncle Zhou, is everything okay at home these days?" Mu Yuheng asked.

Butler Zhou nodded, a relieved smile on his face, "Everything is fine in the mansion, but the young lady misses the young master and the young lady every day."

When Mu Wanwan heard Butler Zhou mention Chao Chao, her heart warmed. She quickened her pace, wanting to see the cute little guy as soon as possible.

In the City Lord's Mansion, Mu Chongli and his family were having dinner.

As soon as Chao Chao saw Mu Wanwan, his eyes lit up immediately. He put down the dishes in his hands and ran over to hug her.

"Second sister, you haven't come to see Chao Chao for so long, I miss you so much!"

Mu Wanwan pinched Mu Chaochao's little round face, took out a large Kuromi doll from the space and handed it to Mu Chaochao.

Mu Chongli stood up excitedly when he saw the person outside the door.

Thanks for your support, everyone. Could you help me think of a way to address Si Yuchen and Si Yuan? One was the crown prince during the reign of the Emperor, and the other is the current deposed crown prince. Having two crown princes would be confusing.
