Everyone who tasted the breakfast on the table praised it highly.

Seeing this, Wang Simeng couldn't help but laugh and say, "Hehe, if it's delicious, everyone should eat more. Once the mall is built, all these foods will be available for sale."

"Haha, that's great!"

After breakfast, everyone followed Wang Simeng to the high-tech machinery.

Everyone stared wide-eyed at the sight of the strangely shaped, large iron contraptions before them.

"This...this is the machinery used for building houses? This is amazing!" one of the workers exclaimed, wanting to touch it but not daring to.

"Okay, I'll explain how to use it to everyone one by one. If you have any questions afterward, feel free to ask me," Wang Simeng said with a smile, and then began introducing the machine.

"This is called an excavator. It's specifically used for digging and building city walls. It can be used to dig up soil and rocks. Its function is very simple." Wang Simeng smiled and took out a palm-sized operating device, then turned on the display screen on it.

"This is called the operator, and the lit part on it is called the display screen. The display screen can show the excavator's perspective from all angles."

Below are some buttons; the red button is for starting. The four small buttons on the right are for forward, backward, left, and right…

Wang Simeng explained to everyone how to operate the excavator using the controller.

"I see." Everyone suddenly realized. They then discovered that operating an excavator was so simple.

"Sirs, this machine has many functions. As long as there is sufficient power, it can start the excavator in a short time."

"Moreover, these machines are all solar-powered, and the charging speed is very fast," Wang Simeng said with a smile.

"Ahem! Miss Wang, what is solar energy?" one of the officials from the Ministry of Works couldn't help but ask.

"Ah! Solar energy! Simply put, you can think of it as a form of energy."

Just like us humans, when we're hungry we need to eat. After eating, we have the energy to work. These machines work the same way.

"But they don't eat grains like we humans. They get their strength from absorbing sunlight," Wang Simeng explained in a way that people in ancient times could understand.

"Oh, I see. It's so amazing." Everyone's gaze towards Wang Qin changed. They never imagined that such a powerful thing existed in the world, which shocked them greatly.

Wang Simeng spent the entire morning explaining how to use all the machines.

“Everyone is welcome to give it a try,” Wang Simeng said to the crowd.

Upon hearing Wang Simeng's words, everyone picked up the operating machine and began to try it out.

Everyone tried it out, and just as Wang Simeng had said, the excavator was very convenient and could be operated with ease.

"Wow, that's amazing! This excavator is incredible!" an employee from the Ministry of Works exclaimed excitedly.

"Not only can it excavate, but it can also operate autonomously. It's fantastic," another person said.

"Yes, it's amazing. If we used these machines, we could save so much time and manpower."

"If we were to mine in the mountains, this would be much faster than using manpower!"

"This machine is also very powerful..."
