Overall, power system is inspired by cultivation novels, with Western setting.

Blood talents - Mana Core

Blood talents are powers obtained from birth that lay dormant within a body and can be awakened by some special techniques or artifacts. There are five ranks, categorized based on growth potential and the ability to utilize mana. 

Common Rank: The most common type. Individuals with Common Rank blood talents have very limited growth potential and require significant effort to progress. They most likely cannot sense mana well and cannot learn to cast magical spells. 95% of the population in this world belongs to this.

The MC (Jack) has Common Rank blood talent. He cannot sense or use mana. 

Heroic Rank: With a solid foundation for growth in physical and magical abilities, those with Heroic Rank talents have moderate potential and can become relatively powerful through consistent effort and training. In fact, most knights and mages working for the Kingdom are selected and raised from those with this type of talent. This is also the baseline of summoned individuals. But compared to the other three types, it's nothing special at all.

Sacred Rank: Extremely rare types that offer high growth potential, with the ability to grow and utilize mana ten times more than Heroic types. Archmages, Royal Knights, and most members of the royal families have this type of talent.

Legendary Rank: ten times stronger than the previous rank, and people having it will certainly end up as the strongest in this world. Only a few people currently have this.

Divine Rank: a myth, a legend among legends, even among gods. Individuals with this type of blessing are only documented in ancient texts of lost civilizations. Not only could they easily become the most powerful heroes, but they could also triumph over gods.

Power ranking system

jobs like Warriors, Mages, and Assassins also have different ranks depending on the person's power level. When it comes to Warriors, the rank is based mostly on physical abilities.

Beginner Warrior: Can punch through brick walls easily and knock down small trees, capable of winning against an adult bear.

Master Warrior: Able to shatter boulders with a single punch and outrun a galloping horse over short distances. Their strength and speed are enough to take down multiple armed opponents effortlessly.

Elite Warrior: Can break through reinforced stone walls with their punches and move fast enough to dodge arrows at close range. Their stamina allows them to fight for extended periods without tiring.

Despite having the weakest blood talent, MC's body has been enhanced by modern technologies thus reaches this rank. 

Champion: Capable of pulverizing iron with their fists and moving with such swiftness that they appear as a blur to the naked eye. They can engage in prolonged battles against numerous elite opponents without breaking a sweat.

Destroyer: Their punches can create craters in the ground, and their speed can sometimes break the sound barrier. They possess immense endurance, able to fight for days without rest, and can take on entire armies single-handedly.

War Saint: Can obliterate entire sections of a castle with a single punch and move with such speed that they appear to teleport. Their resilience allows them to withstand attacks that would annihilate lesser beings, and they can sustain high-intensity combat for weeks on end. 

War God: The impact force from a punch can smash a mountain to bits. They can move at speeds that are several times the speed of sound, and their stamina is virtually limitless, allowing them to fight for months without fatigue. Their very presence on the battlefield can turn the tide of wars.

Enchantment system

Enchanting is the art of writing magical "codes" on item to give it additional attributes. The language used is Arcanum, the language of Gods.

General rule:

- Must be written using a special kind of ink invisible to the normal eyes. Only those with a special skill called Enchanter's Sight can see it.

- Items cannot be enchanted over and over again limitlessly. Successful enchantments will consume points. If exceed limit, item will break.

Enchanter ranking:

- Novice -> Apprentice -> Master -> Grandmaster

-------------------------

Arcanum rule

Reading

- Do not read Arcanum for too long. This is the divine language, looking at it is like looking at the sun itself. Staring at it for too long causes mental damage. The stronger the enchantment is, the more damage it causes.

Speaking

- Arcanum has to be spoken with intention. Any word, even if it is as holy as the gods themselves, is useless without intention behind it. 

- Speaking forbidden words may be catastrophic.

Writing

- Enchantment ink is required to write Arcanum. Without it, the words disappear right away without any effect.

- Can be written in 3D. Letters can stack on top of each other.
