Modern Cultivation : The Strongest Couple Bonded by Vampire System

[The material used for the crystal should be easily accessible in this area; otherwise, they wouldn't use it for all their construction.]

[But I doubt they use blood. Currently, King's blood has a high concentration of Life Force energy, so a single drop is enough, but for normal beings, their concentration will be far lower, so if they really use blood to activate this many items daily, it will require much blood killing many of them, or they need to capture other sentient being for this.]."

Alex realized Vesa was correct, based on everything he had seen so far; the people here seemed to be a tribe that liked to live peacefully; he hadn't seen anything that looked like a weapon.

He then took out a bottle of the spice water and started dripping it into another shard of crystal. To his surprise, the crystal reacted just the same as when he dripped his blood on it.

"Since spice water has a similar effect to Life Force, this means I should be able to activate the crystal by pouring Life Force energy into it."

Alex then tested it on the crystal; he started pouring a bit of Life Force into it, getting a similar effect just like using spice water.

He then started experimenting with the amount. The result was astonishing for him.

Once energy is poured, the crystal will be turned on for a while, just like a phone that needs a charge. He also found out the crystal seems to have an effect on filtering the air surrounding, explaining the reason why the air is so fresh.

Looking at the many crystals around him, Alex started laughing. He began feeling greedy, wanting to bring all the crystals back with him.

Even without further analysis, this crystal is the best material to build a house.

This can also help improve AweCube, increasing efficiency many times since he doesn't need to worry about producing high-quality air for the inhabitants. Using this crystal as part of the construction material will be more than enough.

Of course, Alex won't use it like the habitant here, building houses completely from the crystal since no matter how many crystals he can get here, it's still only a limited amount. If he doesn't use it sparingly, it will quickly run out.

However, the one that excited Alex the most was how the crystal reacts to life force energy.

He cannot wait to return home and start experimenting with it, wondering if he can use this to create a special weapon and armor for a vampire progenitor-like him.

"Vesa, did the old progenitor have his own weapon?"

[Of course, he did, King, but the old progenitor only treated those as toys since he hadn't found any material strong enough to be used by a progenitor.]

[For example, this crystal, in the past, there are also similar materials in Eldonia.]

[We named it Bloodstone; creating a weapon with it will greatly enhance combat ability for a Vampire, but for a progenitor, it's still too weak.]

[The material cannot hold the power of the progenitor and is easily destroyed after one use, even when he barely uses ten percent of his power.]

This confirmation is enough for Alex. What he wanted to know is whether the vampire race in the past used weapons that could maximize life force energy, and the answer is yes.

Even though it's not good enough for the old progenitor, for him and Minyue, weapons made with material like this will boost their combat power to a new level.

Rather than using life force in a burst, they will be able to use the weapon to help regulate the use directly in combat. This will also help them learn how to manipulate life force energy.

Alex then remembered he had another type of crystal, the one with a symbol in the middle of it.

"Now I wonder if the symbol is something similar to a rune or formation, changing the effect of the crystal."

He then took out all the crystals with the symbol he got onto the table.

The first one has a symbol like water but with a trident surrounding it.

After the last experiments, he found out that, weirdly, spice water has better efficiency in activating these crystals, even better than his own life force.

"This spiced water comes from that desert loch ness; I wonder if these crystals also come from that monster."

Alex then started thinking about a way to capture that monster, but he quickly shook his head. It's too dangerous for him to do this now; he needs to at least wait until he gets stronger first.

The risk and reward now is just not worth it.

Alex then started testing it; he poured the spice water into an empty bowl. Next, he put the crystal with the symbol into it.

Swosh...

The moment he does that, the crystal starts glowing a brilliant green, and a cold aura spreads outward, creating a frosty mist around the crystal.

Alex can see that the water in the bowl, instead of getting frozen, starts reducing in volume quickly. It doesn't take long for the water to completely dry up. At this point, the crystal still emanates the cold aura, but the glow turns dimmer.

"Maybe they use this to keep their food fresh. If I put this in a closed container, it should work like a fridge," Alex mumbled to himself.

He then tested the other crystal. One of the crystals with a symbol that looks similar to the sun can create light around it.

This confused Alex at first since normal crystals are also able to do that. Why is there a need to make a unique one just for this purpose?

After testing with the amount of water he put in, Alex then found out the reason. The crystal's brightness and color change depending on the quantity and purity of the spice water.

The more pure the crystal will glow white; the less pure the crystal's color will grow dark. As for the real use of it, Alex speculates they probably use it as a toy for the kids.
