Awesome! My best friend traveled through time and space and became the infrastructure queen

Night falls.

Inside the White Bear Country’s army camp, the left vanguard was being scolded by the commander-in-chief, General Lei Shi.

"what's wrong with you?"

"We sent 500 people out to capture some water wheels, but we couldn't get them back? And almost the entire army was wiped out! What on earth are you for? What use are you?" General Lei Shi was so angry that his face turned red and he smashed several cups in a row.

"General, I am also worried about the Second Prince. As long as the Second Prince doesn't come back, I won't be able to sleep or eat." The left vanguard lowered his head, his voice filled with grievance and sigh.

General Lei Shi became even angrier when he heard this. "Does the Second Prince's life matter, but the lives of the other soldiers are worth shit?!"

The left vanguard knelt down and said, "I dare not! Today, the Ningguta side used some guard equipment that we have never seen before. The arrows flew like rain, and we had no power to fight back."

"Huh! How is that possible? You must have underestimated the enemy." Lei Shi didn't believe it at all.

The left vanguard dared to be angry but not to speak out.

General Lei Shi's status in the White Bear Kingdom is second only to the prince. No one in the army dares to disobey what he says. The previously arrogant Zuo Xianfeng is now like a quail in front of him and has long lost his former arrogance.

"Send another 5,000 people tomorrow morning. If Ningguta doesn't release them, just charge and massacre the city." General Lei Shi said coldly.

"Yes, I will obey your command." Zuo Xianfeng responded, but his heart was full of worries.

……

Inside Ningguta.

Su Chengnan and his men had just arrived at the carpentry workshop.

Before I even reached the door, I heard the sound of busy work inside.

"Everyone, hurry up and work harder!"

"Come on, three, two, one, lift!"

"Sixth brother, it's ready here, come over and take a look."

Voices came from inside, and Su Chengnan led people in.

I saw that two large mobile catapults were about to be completed, and the huge wooden frames looked particularly spectacular under the firelight.

Su Chengnan tilted his head and looked at it for a long time. He felt that it was very consistent with what he had imagined in his mind, and he couldn't help but feel more confident.

When Liuzi and his companions saw Su Chengnan, they quickly put down their work and walked towards him. Although they all looked tired, their eyes were still bright.

"Is it almost finished?" Su Chengnan asked.

"Yes! It just needs some final proofreading, which will take about half an hour."

Su Chengnan walked inside, circled the new catapult a few times, and tried out its wheels himself. "It's really good. After installing these wheels, only three people are needed to operate it. One person throws the stones, and two people relay them to load the stones."

"Miss, can you take a look at the device that adjusts the launch angle and force?" Liuzi jumped onto the operating table and tried to tinker with it.

Su Chengnan took a closer look and felt that this large machine was 99% similar to the machine in the space video.

"It looks very good now, far exceeding my expectations." Su Chengnan smiled with satisfaction.

"That's good! Now I feel relieved." Liuzi jumped off the equipment.

Bingsan supported Liuzi, and Su Chengnan put her hands together and clapped them three times. "Thank you for your hard work, everyone. I believe these city defense equipment will definitely improve our defense capabilities! Keep up the good work, and try to make a few more sets of catapults before dawn, so that we and all the people can be safer!" She encouraged loudly.

"Yes!"

"Don't worry, Miss! We will definitely work hard! We will never let you down!

"Yes! Fight for the people!"

Everyone answered in unison.

Su Chengnan waved his hand, signaling everyone to continue working.

She led Liuzi aside and instructed him, "Once you're done here, immediately take them to the city gate. I'll have the city's officers and soldiers come over to assist with manpower."

"Just pull it over? Isn't it too early?" Liuzi was stunned.

"Don't pursue perfection at this time. Put the painting aside for now. As long as the functions are complete and the debugging is trouble-free, you can put it into use."

"Then put it directly outside the city gate?"

"General Zhong has reserved a dedicated area for you by the city gate. All you need to do is arrange everything neatly. Just hurry up and ensure the quality and quantity are met. I'll let others take over the transportation."

Liuzi nodded repeatedly. He really didn't have time to worry about other things.

"Okay, then let's hurry up and finish it as soon as possible. Miss can send someone over now to get those spare parts."

"it is good."

Su Chengnan turned his head and glanced at Bingsan. Before he could say anything, the secret guards hurried away to arrange for manpower. They had perfect tacit understanding.

"I'm leaving now, you guys continue with your work."

"it is good."

……

It's not enough to have a catapult alone, you also need enough stones.

Moreover, according to the plan discussed by Su Chengnan, Zhong Yinghan, and Sun Liangyuan, they all believed that not only should there be catapults outside the city, but two should also be placed inside the city, on the left and right sides after entering the city, just in case.

"Let's go and take a look at Stone Mountain," she said.

"I've already told them to quickly select suitable stones. I guess they're almost ready now," added Bingsan.

Su Chengnan paused, hesitated for a moment, and finally decided to go.

Seeing this, Bingsan ordered a carriage to come.

"Miss, it will be faster to take a carriage."

"it is good."

Su Chengnan got in the car and the group quickly headed over there.

When we got off the car, we saw that the officers and soldiers had already pushed the stones of appropriate sizes neatly together, and there was a dosage flatbed truck parked next to them, ready to set off at any time.

But there was a small group of people gathered in the back. Su Chengnan frowned slightly and said, "Let's go and see what's going on."

"Yes."

Bingsan quickly squeezed into the crowd.

Soon, Su Chengnan heard Bingsan's scolding, "Stop!"

Su Chengnan frowned and walked over to see what was going on.

As she walked, the crowd gradually dispersed, revealing two people lying on the ground, dying. Their bodies were covered in bloody whip marks, and they seemed to be unconscious.

Bing San restrained the officer who had attacked him and asked, "Why did you hit someone?"

The officers and soldiers were unconvinced and struggled, saying, "This guy is cunning and treacherous! What's wrong with me teaching him a lesson? If I don't serve as a warning to others, what will happen if others follow suit? We can't even do this job anymore!"

Su Chengnan looked at the expressions on the faces of the others around him and felt that there was something else going on, so he asked, "What's going on? Tell me."

Someone fell to his knees with a thud: "Miss, help me, please help me."

"Miss, please help me!" Everyone knelt down.

Su Chengnan's face darkened, and his tone unconsciously took on a frosty tone. "What's going on? Tell me!"
