I traveled through the plane space with the trading system

Meng Kexin suddenly remembered that there were still many watermelons in her space. This season was the perfect time to eat watermelons to cool down.

She just flipped her hand and several big, round watermelons appeared on the floor of the room.

Meng Weiyuan and Qin Wanying were delighted to see this item. "Xin'er, did you also get this in the trading system?"

Meng Kexin said with a smile, "Mom and Dad, this is a planting space my system rewarded me with. I planted the watermelon seeds I exchanged from the modern world in it. While learning about the planting space, I discovered a new function of the space. This planting space has one-click sowing and one-click ripening functions, so I have a lot of big watermelons."

"What are you waiting for? Kill it and eat it!" Meng Weiyuan said anxiously.

"What are you going to kill to eat? Why don't you wait for us brothers?"

Meng Kehan's voice rang out from outside, followed by Liu Chenyi and the Yu brothers.

After they came in, they bowed to Meng Weiyuan and Qin Wanying and said, "Greetings, Master! Greetings, Master's Wife!"

Then he saluted Ye Muyuan and said, "Greetings, big brother!"

Meng Weiyuan was very pleased with their attitude and introduced them, "That thing on the ground is called watermelon. It's a must-have summer fruit to cool down. Han'er, go get a knife and cut the watermelon. Let's eat it together."

Meng Kehan responded and hurried to the kitchen to get a knife. He cut the watermelon open, and immediately, a sweet aroma filled his nose.

The red flesh of the melon made everyone salivate.

"Wow, it smells so good!" The younger brother of the Yu family couldn't help but exclaim in admiration.

"Come and try it!" Meng Kexin greeted everyone with a smile.

Everyone picked up a piece of watermelon, took a bite, and couldn't help but sigh at how sweet and juicy the watermelon was.

Ye Muyuan also tasted a piece and sighed in his heart that this watermelon was so delicious.

On this hot summer afternoon, the family sat together, enjoying the cool and refreshing watermelon, and they were very happy.

After eating the watermelon, everyone sat together and heard Meng Kexin say, "Dad, you see, our family now has very convenient access to water. Other places in Hangu Pass still use the ancient method of getting water, which is very inconvenient."

Yes, when there were outsiders present, Meng Kexin would call Meng Weiyuan "Dad" and Qin Wanying "Mom".

Meng Weiyuan nodded in satisfaction after hearing his daughter say this. "Xin'er, getting running water to Hangu Pass is no small undertaking!"

"But if it succeeds, it will be a great thing that will benefit the people." Meng Kexin continued, "I want to pool everyone's wisdom and work together to come up with a feasible plan."

Ye Muyuan looked at Meng Kexin with admiration, thinking that she was not only kind-hearted but also very intelligent. He said, "I can mobilize some funds and manpower to support this project."

Liu Chenyi and the Yu brothers also expressed their willingness to help.

So, several people began to discuss heatedly how to divert water, build pipelines, set up water stations, etc.

Meng Weiyuan looked at this group of young people with hope in his heart. He believed that with their efforts, Hangu Pass would become even better.

Meng Kexin opened the system mall and started searching inside. Her eyes were attracted by a name called "towerless water supply equipment". She clicked on it and took a look. She was so happy that she almost jumped up.

"Dad, I found a high-power towerless water supply device."

Meng Weiyuan hadn't expected his daughter's store to actually have such a thing. He said excitedly, "Then take a look at the manual to see how this device works and whether it's suitable for use here."

Meng Kexin nodded, "Dad, I've seen it. This towerless water supply equipment is a water supply system that uses a pressure tank to store and regulate water. It mainly consists of a water pump, a pressure tank, a control system, etc.

When a user uses water, the water pump draws water from the water source into the pressure tank. As the amount of water in the tank increases, the air pressure gradually increases. When the air pressure reaches the set value, the water pump stops working, and the water in the pressure tank is supplied to the user by the action of air pressure.

When users use less water, the water level in the pressure tank drops, and the pressure also decreases. When the pressure drops to the set value, the water pump starts again to replenish water in the pressure tank. This cycle repeats, achieving continuous and stable water supply.

Everyone listened carefully to Meng Kexin's introduction, but Liu Chenyi and the others were completely confused and had no idea what Meng Kexin was saying.

Only Meng Weiyuan's eyes lit up as he listened. "Xin'er, this towerless water supply equipment is great. Let's choose this one. What's the price?"

Meng Kexin glanced at the price tag and said casually, "Dad, the price is in points, which is a copper coin."

Meng Weiyuan converted it in his mind, which was 233 taels of silver.

A bit expensive!

He then asked, "So what does this towerless water supply system include?"

Meng Kexin glanced at the manual and said with a smile, "Dad, this equipment includes a 4.5-ton national standard 5.0 thick stainless steel fully automatic large-capacity towerless water supply, an intelligent variable frequency, self-priming and boosting water pump, a filter with an intelligent switch, and a sensor for the intelligent switch."

Hearing Meng Kexin's narration, Meng Weiyuan nodded frequently, "Let's choose this one. This is enough for the daily water needs of all the soldiers in Hangu Pass."

Meng Kexin placed her order without hesitation, and a flash of inspiration struck her. She turned to Meng Weiyuan beside her, her eyes gleaming with excitement, and said, "Dad, listen! I just had a new idea! When we lay pipes in the future, we can consider separating domestic sewage from bathroom wastewater."

The ordinary domestic sewage generated on a daily basis can be used to irrigate farmland; and the sewage discharged from the toilets is concentrated in a specific area and converted into fertilizer through special methods. In this way..."

At this point, Meng Kexin paused, as if to organize her thoughts, and then continued: "First of all, doing so can effectively prevent the mixing of two sewages of different properties, reducing the pollution pressure on the environment.

Secondly, using domestic sewage to irrigate fields not only saves water resources, but also provides nutrients for crops and promotes their growth, which can be said to kill two birds with one stone.

Furthermore, collecting toilet sewage and converting it into fertilizer not only solves the sewage treatment problem but also creates a valuable resource. Why not do it?

Moreover, if this plan is implemented, it may attract the attention and emulation of other villages or towns, leading to the improvement of environmental awareness and agricultural development in the entire region! Dad, what do you think of my idea? "

After saying that, Meng Kexin looked at Meng Weiyuan expectantly, waiting for his response.
