"What's the look of this dress?"

Diana saw that Charles was taking out a fully enclosed protective suit, or a high-pressure air tank that could move in places that were not suitable for breathing.

Unlike previous protective clothing, this set of clothes shines silver, and the outermost layer is a slightly strange metal film.

Charles introduced: "This is the latest Misilian-aluminum alloy-coated protective clothing. The innermost layer is pure cotton, the middle layer is the skeleton layer and the sealing layer, and the outer layer is Misilian and aluminum alloy, which is extremely suitable for use in confined spaces with dense magic elements."

"We have a confidentiality project at home, only Pomegranate Leaf and I know."

"Change in protective clothing and I'll take you to see."

After he finished speaking, he began to help Diana take off her soft home robe, and then couldn't help but stretch out her hand and pinch it, but the steel ring was pinched and deformed.

Diana, who was suddenly attacked, shouted softly, pressed her on the bed and fisted her to greet her.

Unexpectedly, this action ignited Charles' flames instantly, and he immediately used his wrestling skills to fight back.

When they put on their protective clothing seriously, it was a few days later...

Since an underground maze was discovered on the edge of the Meccaden family territory, many adventurers have come here to develop this underground maze rich in fire elements.

What those adventurers and businessmen could not imagine was that almost all the hotels here were hot spring hotels.

Even the cheapest hotel has a bathtub for people to bathe in the room.

Using geothermal resources and other techniques is not worth mentioning for Charles.

For adventurers, being able to take a comfortable bath after returning from an underground maze adventure and wash away fatigue is an undeniable choice, even if the price is a little expensive.

Anyway, experienced adventurers will calculate the balance of income and break even, and will not return empty-handed in one action, resulting in the financial bankruptcy of the team.

If they really have no money, they can still go to the maple forest to hunt monsters and make money.

But these adventurers didn't know that there was a huge treasure house hidden deep in this underground maze.

If adventurers could find out about this now, they would... be beaten by Charles.

In a huge underground cave, rich fire elements floated in the air like fireflies.

In the light of the fire element, you can see several clusters of top-quality magic crystals of priceless castles on the ground near the rock walls. There are countless dream crystals embedded in the surrounding rock walls. What makes people feel a bit strange is the golden pyramids in the cave.

These pyramids are less than two meters high and are arranged neatly in a 9×9 matrix.

If you observe for a long time, you can see that fireflies-like fire elements will be sucked in when they approach the pyramid.

Diana soon thought of the artificial fire gold technology released by Shield Bridge Academy at this year's Carnival, and asked Charles on the side through the communicator inside the protective suit: "Are you producing fire gold?"

Charles replied: "It's not. All I need is a sub-fire gold with some of the nature of fire gold. As long as ordinary copper is refined into an alloy with a very small amount of this sub-fire gold, the demon resistance will be greatly reduced."

"Professor Kilby and I have calculated that the size of a radio using this alloy can be reduced to the size of a person's head, and citizens with a little money can afford it."

"In addition, many magic items can also be used to add other magic materials to reduce the resistance of magic by adding sub-fire gold."

Diana carefully observed a pyramid and found that it worked the same way as in the Carnival report, and it also made some optimizations.

She said: "This is indeed a good industry, I just don't know how much profit it is."

"This is just a place to do experiments, and it's not possible to do large-scale production here," Charles said.

Diana thought of something and wanted to tease him, but after thinking about it carefully, shelved it. This is not a place.

Charles took her to the rock wall of the cave again, where there were a large number of dream crystal balls embedded.

"These are the dream crystals of all kinds of knowledge I have collected," said Charles. "I plan to build this place into our gold finger. If our descendants are in a downturn in the future, they can turn the tables with the knowledge and wealth here, and at least they can collect tickets."

Diana took a dream crystal ball and went into her dream and took a look. It was a standardized large-scale breeding technology for dairy cows.

She looked at several around her, namely, the orchard ecological chicken raising, efficient meat sheep raising, and high yield and efficient sows.

When she saw the efficient feeding of gooses and the processing of products, her body subconsciously trembled, and she remembered the days when she and her aunt were chased by gooses in the village when she was in her hometown when she was a child.

She put the dream crystals back and said, "The solution is good. I'm afraid that their baby will not feel bad when they sell their sons, so they will sell them all."

Charles nodded after hearing this, and then said seriously: "Then we have to have more children. The gourd baby starts and will not be topped off. At that time, if there are more people, you will understand the truth."

Then Diana gave him a few kicks.

"Do you treat me as a sow?" Diana said as she kicked.

Charles just said "haha" a few times, then shouted to the surroundings: "Pomegranate Leaf!"

Then he said to Diana: "Thanks to the pomegranate leaves, otherwise others wouldn't be able to build this place."

As soon as the words were finished, a white figure fell from the top of the cave, and it turned into the shape of a pomegranate leaf after a moment.

It's just that she didn't wear anything, which made Diana, who saw her body for the first time, stunned for a moment.

Although her face is beautiful, her torso is a bit perfunctory, as smooth as a model in a clothing store, with only some curves that can be divided into two sides.

Charles reached out his hand to condense a large ball of active space elements outside the protective suit, and the pomegranate leaves immediately went over to suck.

"It's really thanks to her here," Charles continued. "We left the city of Knowledge and did our job alone."

Not long after, the pomegranate leaves had a full meal.

Charles said to her: "Next, please be optimistic about this place. We have something to do and we can't be disturbed."

After the pomegranate leaves saluted, they disappeared into the cave.

Charles first used the power of the Demon-Destroying God to condense into a yurt-like shield, then made a semicircular igloo inside, then took out a few high-pressure gas cylinders and opened them, and began to fill the igloo with air that can be breathed.

After all this, he laid a thick layer of mats on the ground, and finally took off his protective suit and said to Diana: "You take off the protective suit, as well, the next thing is the key."

Diana kicked him again angrily.
