Lux took a few seconds before replying: "then, the country would have been demolished that time"
...
David was disappointed as he didn't get the right answer from lux. He wants to know lux real identity but asking him further would only make lux beware of him, so, to not make enemy with each other, stopping now is a better choice since they are now friends with each other, asking questions about personal info would break their friendship although they don't kinda trust each other the fact that their same friends consider them a friend is enough to tell that they are friends too since they shared some memories that only happen a few times in this kind of world, also, having a strong friend is also beneficial for him and David understand that, overall David sensed that Lux is not some kind of villain like others after spending time with him. Without any choice he replied as if it was a normal response: "I guess so"
"....."
Silence filled the entire room as the two refused to talk any further and patiently waited for 2 more minutes while lux went back to what he was doing earlier by observing the entire room.
While examining the entire area, lux found an unusual spot behind the sleeping monster.
"!!!"
From a normal person's perspective will not be able to notice this spot since it's from the back of a massive monster which is 2 kilometers with a gigantic body that could destroy a city by laying on top of it.
To make sure that his hunch was right, lux moved to an area where he could see what was in the back of the monster.
As lux approached the area, a small light can be seen from the back of the monster, and soon a passage that goes into another room appeared.
"It's finally time, I guess I will have a long sleep later after arriving at home," said David as he gets up from the ground and looks for lux.
"What is he doing?" Added David after noticing lux from another area looking for something and said: "He seems to be looking for something. Well, I will find it out after coming there" david goes towards lux.
When he arrived next to lux, he questioned him out of curiosity: "where are you looking at?"
Hearing that, lux looked at him before pointing his finger to the cave.
David looked where he was pointing and found a cave that seems to be going from another room.
David was surprised to see this and tried to guess what was inside it. it might be a treasure room or a room full of monsters stronger than the previous monsters they saw all the way here, whatever it is they need to find it out.
"I think we should explore it" said lux.
"Yeah, since our mission is to investigate this place, we should at least know everything inside" David nodded in agreement.
"Should we use the potion?" Lux questions him.
"No, we need to use it when we come back, Let's just use this advantage while it's still asleep." Said David.
Lux nodded. Their potion is only limited so using it constantly without thinking is not good for their situation.
After some more talking and agreeing with each other, lux and David disappeared from their spot and started investigating.
Lux and David effortlessly infiltrated the cave while the dragon snake is defenseless.
Arriving in front of the cave, lux and David noticed the shining door with some strange runes on it that seems to be responsible for creating the light earlier.
In an instant, lux and David realized that the only way to get inside is to destroy it.
"These are ancient runes" said David as he touches the runes to inspect them.
"Do you know how to dispel them?" Lux questioned him.
"I know the magic that can dispel them but the first key to dispelling it is to understand these runes first and it takes some time to do it since these runes are so very complicated because it's the first time I saw them." - David explains.
"Is that so, well, I have a magic that can dispel it in a second" lux said.
Hearing that, David looked at him confused and said: "you do?"
"Well, let me show you" lux walked towards the door and touched it.
David took a few steps back and observed what lux is trying to do.
After touching the door, lux did not delay it any longer and starts dispelling it.
"Absolute magic. Runes absorption" saying that, the runes on the gate got absorbed by lux hand in a few seconds.
The gate starts opening now that it doesn't have any runes restricting it.
David who was watching the entire scene dropped his jaw in shock.
"You..." Without finishing his word lux cut him.
"It's a secret okay, don't tell this to anyone." Having said that, lux entered the door.
*sighed* David helplessly followed lux with so many unanswered questions inside his mind.
The two went inside without noticing the tail of the snake started moving
...
Inside the room, lux and David were at a loss for words after seeing the scenery in front.
"This is... A treasure vault"
Seeing the enormous amount of gold in front of them, lux and David turned into a businessman.
"How do we split it?" Said lux.
"As a professional businessman, it's better to split it 50/50" - David.
"Deal" both of them did a handshake as a sign of agreement.
But, David realized something and spoke: "how can we bring it with us?"
"Did you forget about my dimensional storage?" Lux reminded him how he gave him those t-shirts in school.
David finally remembered after hearing that and burst into excitement. "Yoooo!!!" Of course, all those golds are at least worth hundreds of millions of money who wouldn't get excited with that?
"Let's inspect those books first and find something interesting," said lux as he points his finger to the books he found from a certain area.
Having heard that, David nodded. It's better to split some things they find that suit their interest first.
Lux and David immediately searched some and read the books and took them if they find them interesting.
After 5 minutes...
So far, lux and David found some books that contain some stories of history and some books that involve ancient magics, runes, and techniques, of course, there are also some that they don't like and ignored them but, in the end, they still bring it for others as a souvenir.
After some quiet time, lux goes to some areas for research purposes.
While searching, lux found a room that contains hundreds of swords inside and immediately told david.
"These are some high-class swords, I can guess they are all b-s rank swords." Said David after examining all swords.
"Let's split it then. I will take the swords that I like and you take yours and the rest we don't like will be given to others." Said lux.
David nodded and starts searching for swords that they like.
"Hmm, what kind of sword should I pick." Lux wondered what kind of sword he should pick. "I like katana so I should pick them" he added.
After a few minutes, lux saw nothing that suit his fighting style. Meanwhile, David in the background is taking almost all swords in his sight.
While searching for good swords, lux found a button, and press it without thinking what was going to happen just for fun.
"it's just my instinct told me" he said after pressing it.
With that, a hidden room opened in front of lux.
Inside the room, four swords are emitting a frightening aura around that could kill hundreds of people just by pressure alone.
as soon as the figure of lux appeared in front of them the swords released a strong killing intent. - "A human huh,"
Lux who just entered the room remained silent as he is under the pressure of killing intent.
David also felt the killing intent and looked at the sword for a brief moment before turning back to what he was doing like it was normal.
"....."
Lux under the pressure of the sword remained silent as he was observing them.
There are four swords in total, unlike the other three which are not talkative like the other one they just remained silent as if it doesn't have consciousness, but lux already know they have.
Ignoring the pressure of the sword, lux walks forward to the sword that he saw on the right side, completely ignoring the other one.
"This human" - surprised by lux behavior.
"This sword is..." Lux as he pulled the long sword.
The sword tried to resist lux by putting his soul under the pressure but, it didn't stop lux from unsheathing the sword.
To stop it from resisting, lux filled the sword with his soul energy as he unsheaths the sword.
Feeling the soul energy of the holder, the sword stopped resisting and acknowledged lux as the owner of the sword.
'As I thought this is sword is my soul mate.' Thought lux before returning it to it's scabbard
