The place where the person has transmigrated is a very vast world and the people don't even know the history as most of the records have been destroyed, so there was a very powerful formation master who used the formation to create a base in such a way that monster was separated from each other forming a difference of lv.15.

The monster outside the base is generally present in the forbidden zone. Which only provides you with resources and experience.

Each base has a 30km safety zone, after that comes the forbidden zone where the monster rules. The low-level monster or ordinary monster fights on instinct, while the greater grade of monster. (ordinary grade> bronze grade> silver grade> gold grade> diamond grade> Platinum grade) they have some wisdom so they can use skills skillfully.

The length of the forbidden zone is 70 km in radius minimum and maximum not known as there is very base, here you can find elixir, monster core, meat, wood, and various other resources. The forbidden zone is ruled by a monster that has built its base in the centre of the forbidden zone.

There are also rules in the forbidden zone, that if you're in base 1 then here the maximum level adventures are of lv.15. So, only Lv.15 adventurers can only enter the boss lair and clear it. High-level adventurers will be banished, except for not entering the boss lair, you can do anything. But killing low-level monsters will not give you experience so, most of the high-level adventurers hardly come here.

Dungeon- Each base has a dungeon, which starts from level 1 but the highest floor differs as the base level increases. Such as base level 1 has the highest floor level 15 while base 2 have the highest floor level 30. And so on. Only inside the dungeon can burst out equipment.

The monster in the forbidden zone when dies, the blacksmith can craft the equipment from it. You can also get some skills, scrolls, props, by killing the main monster in the forbidden zone.

After the main monster or main boss is killed in the forbidden zone, the forbidden zone will gradually become a safe zone. In which the monster generally becomes free, and so they become just like any living creatures, like only if you take initiative to attack, then only will they attack or else they will generally be docile.

Rules-

1. Inside base and dungeon you can't kill but you can use curse and beat the people.

2. Those who violate the rule will be turned into dust by formation.
