Metaphysics tycoons rebuild the underworld in the interstellar

"What you are looking at now is ruby. The energy in it is on the fire side. It can be added to various fuel formulas to increase the flammability of fuel." Yan Chen saw that Lingchu was staring at a kind of gemstone, and started to do science popularization work.

"However, because the energy inside is unstable, you need to pay special attention when using it, and you need to keep it separately at ordinary times, otherwise it is very likely to cause an explosion."

Hearing this, Lingchu understood why these gemstones, which looked so red as black, were placed under a glass cover alone.

Such a hot and uncontrollable gem is definitely not the kind that Lingchu wanted.

Lingchu's gaze was then placed on the green and blackened gemstone next to it.

"This, isn't it an emerald?"

Yan Chen nodded, "It's indeed an emerald. The power in this kind of gem is generally peaceful, with negligible energy, and it is generally difficult to sell."

Hearing the words, Lingchu blinked, then pointed at the one next to him, "Then what is this?"

"The energy of sapphire also tends to be peaceful, but it is a little bit more energy than emerald, but it is said that it is more difficult to use than emerald. The researchers have not yet researched it, and it is more suitable for the use of sapphire, so this kind of gem is generally sold. There are not many of them.”

Lingchu rubbed his chin, and asked curiously, "Then, what gems are better for sale?"

Hearing this, Yan Chen pointed to the side, "This kind, black gemstone."

Lingchu looked over, and there was indeed a row of translucent black gemstones on the shelf.

"This is a black gem?"

Yan Chen hummed, "The energy in the black gemstone is not stable, but it is very powerful, and it can be used in many situations, especially in the research room, where it is used in a large amount."

Hearing this, Lingchu walked over and stared curiously at the black gem inside.

Among other things, this black gemstone is so black that it is translucent, and it is quite beautiful.

At least on the surface, it looks a little shiny.

and……

Standing here, Lingchu actually felt a faint yin.

It's not ordinary yin qi, not the yin qi that belongs to the dead, but... like the breath of a vast, endless cemetery.

It's like the breath that should come out of the place of death.

kind of like...

In Lingchu's imagination, the breath of hell.

Has there ever been a hell in this place?

Lingchu put his hand on the glass.

As soon as she put it on, Lingchu felt the Yin Qi lingering around her fingertips.

The power of this kind of yin energy tends to be peaceful, and it is not like the kind of dead person's yin energy that will invade the human body unconsciously.

The Yin Qi in front of him lingered outside the human body and did not invade.

Very measured, with a sense of boundaries.

Maybe it's because of the glass.

Lingchu hesitated and said: "Senior Yan Chen, can I take out this stone and have a look?"

"can."

Yan Chen nodded, and then greeted the mechanical waiter not far away.

The machine waiter immediately came over and pressed the button next to the cabinet.

Immediately there was a burst of red light on the button, which flashed a few times.

In the next second, the glass was retracted little by little.

The waiter made a gesture of invitation, "You can pick it up to watch as you like, but be careful not to get your hands sweaty on it."

Hearing this, Yan Chen picked up the glove on the side and handed it to Lingchu, "Hand sweat can cause energy changes, so be careful."

Lingchu let out a groan, and after putting on his gloves, he picked up the black gemstone.
