As the sun slanted to the west, Yao Zhi and Ling Ershi finally arrived at the location marked on the map. Standing at the mountain peak, she double-checked the mark and said, "It should be here."

Ling Ershi looked at the flat area around them and was full of doubt. "Master, this is the peak. Will there be an underground deposit here?"

Yao Zhi smiled and said, "Maybe."

After she said this, she called out, "System."

The next second, a mechanical voice echoed in her mind. "Host, do you need anything?"

"System, can you help me pinpoint the exact location of the salt deposit?"

Without replying to her, a blue screen popped up in front of her. Unlike the previous map, this map looked more like a radar screen with two red dots, a yellow dot, and green lines moving above the map.

"Host, the yellow dot is the location of the salt deposit. This map can help you pinpoint the location. But the depth of the deposit underground can only be found using the scanning feature."

"Okay, thank you."

Following the radar, Yao Zhi walked around the area.

Although it was the mountain’s peak, it was not covered with huge boulders or made up of small flat areas. Instead, the peak itself was a flat area. While it was not as flat as the ground, there were not many boulders on it. 𝘧𝘳𝘦ℯ𝓌𝘦𝒷𝘯𝑜𝑣𝘦𝓁.𝒸𝘰𝓂

Less than 20 minutes later, she finally found the location and used the scanning feature to check the depth. A few minutes later, the information about the salt deposit was written in detail on the blue screen.

Yao Zhi read the information for a while before she closed the screen. She was surprised that this salt deposit was actually very deep.

The top of the salt deposit was 500 meters below the surface. However, the salt structure itself extended downward to depths of almost 10,000 meters.

What shocked her was that this salt deposit’s diameter was more than 10 kilometers, with a vertical height of several kilometers.

The shape of the salt deposit was also shown in the scanned information, which was a cylinder. This salt deposit held around 100 cubic kilometers of rock salt.

Since extracting the salt from such a massive deposit came with danger, Yao Zhi hesitated. If she let people mine the rock salt using normal methods, the natural gas trapped underground might cause a serious problem in the future.

After she thought for a long time, she called out to her system again.

"System, do you have a safe method to mine the salt while ensuring the safety of the miners?"

"Host, with the current technology of this era, it would be impossible to apply modern methods. Even if you use modern tools, machines, and methods, the possibility of a gas leak is not zero."

When she heard this, Yao Zhi frowned deeply. "Is there no other way?"

"There is always a way when there is a will."

The moment she heard this, Yao Zhi understood the System’s meaning and sighed. "How much is it?"

"Host, you are as wise as usual!" the System praised her.

The next moment, a blue screen appeared in front of her, followed by the System’s voice, "Host, the System can help you mine the salt, and you only need to provide people to transport it."

Yao Zhi read the information on the blue screen and said, "You won’t be so generous as to help me without asking for anything. Speak. What do you want?"

After a moment of pause, the System finally said, "Host, you can’t openly use the tools since it will disrupt this world’s laws. But..."

Before it could finish its words, Yao Zhi interrupted it. "Isn’t it too late for you to talk about me disrupting the world’s laws after giving me permission to produce bombs and grenades?"

The System was stunned by her words for a moment before it replied, "Host, that matter and this matter are not the same."

"How are they not the same? Both are using technology unavailable in this era, and using them brought a massive change to the world’s fate," Yao Zhi asked.

"Well, those bombs and grenades were used to help the Male Lead. He is the beloved son of Heaven. While this salt mining is for your personal purpose. It has nothing to do with the Male Lead."

"What do you mean, it has nothing to do with him? I’m helping his wife earn money to support the massive army," Yao Zhi complained.

"Well, as I said before, the Female Lead can be replaced, but not the Male Lead. This shows the difference in their status in this world," the System replied carefully.

As soon as she heard this, Yao Zhi was angry again. She never expected that this novel world was actually a male-oriented story.

She had to take several deep breaths to calm down before she said, "Continue your explanation."

The System didn’t dare talk about the Male Lead and Female Lead matter anymore and returned to the previous topic.

"Host, this System already negotiated with the Heavenly Dao. As long as you pay 1.5 million merit points, this System is allowed to use the advanced technology bought from the interstellar world."

"The method not only ensures the safety of the workers, but it would also be able to automatically store the natural gas in specialized gas tanks and place them in your storage."

Hearing this, Yao Zhi asked, "You mean that the gas tanks will be automatically stored in my System’s storage?"

"Yes."

"Can I store them in the System’s grassland instead?"

"The Host can store them anywhere you desire. The System will follow your arrangement."

"Then what about the salt?"

"If the Host wants it, you can hire people to mine it manually, and the System will be responsible for handling the natural gas. But if the Host wants to avoid trouble, this System can mine the salt for you and store it in any designated area you wish."

"You are so generous and willing to work for free?" Yao Zhi was doubtful.
