the mc (marcus) , is a country bumpkin. he lives in his countryside living a simple life. he is aged 5 when he starts his journey. a home schooled kid from the country side, how much of common sense can he have? almost everyone who can manifest are tier 0 in his hometown. not only that, no one is allowed to teach the kids under 5 cultivation methods to keep them safe.

the tier system works this way

there are 20 tiers but they are split to 4 levels:

master, lord, saint and lastly supreme

each level contains 5 tiers:

novice, apprentice, skilled, expert and grandmaster.

the tree has 20 branches which corresponds to each tier. on each tier are 5 fruits.

think main skill and sub skills.

for a tier 1 skill like the mc, he has the multiplication ability. the sub skills would be fruits that supplement it. so the current plan for the mc would be to that he wants speed and energy saving. so for his fruits he may choose to continue to use the wrens for more multiplication-like ability or he may use other cores to supplement it.

think of each branch and fruit as a container, to level up to the next tier you need to fill it up. you can fill it up with anything or you can choose to fill it up with only one type of thing.

so some users choose to fill it up with basic cores of a certain element or ability so that there is that sort of purity then use what is dubbed as the lynch pin core to level up.

when spirit is formless it is known as spirit energy.

when it acts on an object it is known as spirit force.

spirit in the air is known as spirit essence.

spirit masters are a title. they can even be a tier 0. they have the ability to channel spirit for various things. they can control spirit energy use spirit force even without manifesting their tree.

you can also think of it as a person who is a fire and ice mage. i may be proficient as a fire mage but i may not be proficient as a ice mage. both uses mana but that does not mean that i will be equally proficient.

also about the world, 80% of the population are tier 0. meaning that most of the kids will end up going home still tier 0.

in a few chapters, the exhibition tournament will begin. so cheer up people, i ain't going to time skip anytime soon i think.

oh and for those who noticed, the concept of tiers and cores are built from the idea of combat continent/soul land
