I traveled through the plane space with the trading system

After hearing Meng Kexin's suggestion, not only Meng Weiyuan supported her, but everyone in the room applauded her.

Meng Weiyuan waved his hand and said, "Xin'er, let's do as you say. Daddy will arrange the manpower, but you'll have to provide the necessary equipment, pipelines, etc. Do you have enough funds?"

Meng Kexin nodded, "Don't worry, Daddy, I have no problem here. Besides, even if it's not enough, I still have many precious medicinal herbs here. I can just take out a few and sell them to the system mall, and the funding problem will be solved."

Qin Wanying said worriedly, "Xin'er, if it's not enough, we still have some precious ginseng at home. You can sell it in the system mall and use it for the construction of Hangu Pass."

Meng Kexin waved her hand and said with a smile, "Mother, I have a lot of good things here. If it's really not enough, I will ask you for more."

In the following period, all the soldiers in Hangu Pass, except those who had to guard the border, were devoted to the transformation of Hangu Pass.

The family of three gathered together to discuss how to arrange the underground pipes for sewage discharge.

Meng Weiyuan said: "I think we can build a main drainage canal inside the pass, and then build some branch pipes to guide the sewage into the main drainage canal." As Meng Weiyuan spoke, he drew a rough schematic diagram on paper.

Meng Kexin nodded and added, "We also need to install a purification device at the outlet of the drainage channel to prevent sewage from polluting the surrounding environment."

Qin Wanying also proposed her own idea: "We can set up some reservoirs in the city to collect rainwater and domestic water for emergency use."

The three of them discussed heatedly and finally decided on a complete plan.

Meng Kexin looked at the drawing and suddenly thought of a problem. The Hangu Pass is now full of dirt roads. When it rains, the roads become muddy.

Over time, these pipes will be clogged with mud and sand.

She suddenly thought of the cement in her previous life, and decided to build Hangu Pass into a modern place in one go.

So she said, "We can use cement to pave the road." Meng Kexin said with a firm look in her eyes.

Ye Muyuan and Meng Weiyuan looked at each other and saw the surprise in each other's eyes.

"Cement? What is this?" Ye Muyuan asked.

Meng Kexin explained: "Cement is a building material that makes roads hard and smooth, making them less susceptible to erosion by rainwater. Furthermore, we can add some special materials to cement to make it even stronger and more durable."

Meng Weiyuan nodded. "This is a brilliant plan. If it can be successfully implemented, Hangu Pass will be completely transformed. But where will the cement come from?"

Meng Kexin smiled and said confidently, "Don't worry, Dad. I have my own way."

She recalled her memories from her past life and knew how cement was made.

Next, all she had to do was find the right raw materials.

In the next few days, she took Ye Muyuan, several senior brothers, and Meng Kehan to look for limestone and clay in the nearby mountains.

After several days of hard work, they finally found a large amount of limestone on the back of a mountain.

Meng Kexin jumped up with joy.

"Wow, there are so many limestones here, and the quality of these limestones is excellent, making them very suitable for making cement."

Meng Kehan walked over and said, "Xin'er, please step aside. I and a few other brothers will collect some samples to take back."

They excitedly collected some limestone samples to take back to camp for further research.

On the way back, Meng Kexin also discovered some clay mines. The quality of these clay mines was also very good. Meng Kexin happily introduced them to everyone: "Look, the soil here is different from the soil in Hangu Pass. This soil is red. I call it clay. It can be used to make bricks and ceramics."

Ye Muyuan looked at Meng Kexin lovingly and said with a smile, "Xin'er, you know so much. Let's take some of this clay back and study it."

After returning to the camp, they immediately began to analyze and experiment with the limestone and clay they had collected. After many attempts and improvements, they finally succeeded in producing high-quality cement.

This cement has strong bonding and durability and can be used to build strong buildings and roads.

With the success of the cement experiment, Meng Kexin was ready to mass-produce cement. She approached Meng Weiyuan and said, "Dad, I've successfully experimented with cement. I want to mass-produce it. What do you think?"

Meng Weiyuan looked at his daughter in shock. "Really? My daughter is amazing. Don't worry, Dad fully supports you!"

With her father's support, Meng Kexin began to look for a suitable venue. As for the equipment issue, she started communicating with 888.

"888, I want to produce cement here, but unfortunately I don't have the equipment. Is there such equipment in the mall?"

"Host, set your sights high. The mall connects all planes. Forget cement-making equipment; even if you want to make missiles, 888 can get you the equipment."

Meng Kexin curled her lips and said, "Go ahead and brag. It's not against the law anyway!"

888's beard was curled up in anger. If it had a beard, [Host, don't disbelieve me, there's a cement factory with advanced equipment in the mall. Due to poor management, the owner's factory went bankrupt, and he's selling this equipment as second-hand goods at a very favorable price, just one gold coin.]

"So cheap? Then buy it quickly." Meng Kexin urged.

[Okay, host, the purchase has been successful. Due to the large size of this equipment, it cannot be placed in the system warehouse, so it is temporarily stored at the transfer station.]

Meng Kexin suddenly thought of an important question, "888, I'm short of technical talent here, what should I do?"

[Host, rest assured, you can buy slaves in the mall. When selling a slave, simply enter "technical talent." Their identities will be the same as the four slaves the system rewarded last time, so they won't arouse suspicion. Others will simply think they're the servants you brought with you.]

If that’s the case, what is she waiting for?

She decisively bought 10 slaves in the mall. They were six men and four women. When these 10 people appeared, they knelt down in unison to greet each other and shouted in unison: "Meet the Master."

Meng Kexin nodded with satisfaction. These people looked very smart and capable and should be able to assist her in her work.

She named the six male servants Meng Wu, Meng Lu, Meng Qi, Meng Ba, and Meng Jiu.

The four female servants were named Mengchun, Mengxia, Mengqiu and Mengdong.

She began to assign tasks, having the male servants be responsible for moving and installing equipment, and the female servants be responsible for cleaning the venue and preparing daily necessities.

Everyone does their job, busy and orderly.
