When he was inside, he absorbed a little bit of very pure energy.
It is even purer than the energy they purified by setting up formations outside in Qin Ming City.
The energy on the periphery of the Supreme Realm is very complex, and warriors below the ordinary Holy Beast Realm cannot directly absorb it.
If it is absorbed directly, it may cause a headache in mild cases and confusion in severe cases.
Therefore, it is necessary to use formation methods to purify.
And using the formation to purify also requires the consumption of black stones.
This is also something that can't be helped.
If you want to develop outside the Supreme Realm, you must arrange such a formation.
Even warriors above the holy beast realm prefer to absorb purified energy.
Instead of directly absorbing the mixed energy from foreign countries in the Supreme Realm.
Of course, after reaching the Saint Beast Realm, a warrior's body can already withstand the erosion of mixed energy.
Even if it is absorbed for a long time, there will be no problem.
However, it is one thing to have no problem, and another thing to like it or not.
Just like warriors, they can live in a place with a bad environment and a very depressing environment.
You can also live in smelly places.
Even if you live there for a long time, there will be no problem.
But no matter which warrior he is, as long as he has no special hobbies, he likes to live in a place with a better environment.
Even warriors in the holy beast realm prefer to absorb purified energy.
The absorption efficiency is higher and the absorption is more comfortable.
Therefore, if you want to establish forces on the periphery of the Supreme Realm, you must deploy such a formation.
Even if there were no warriors below the Saint Beast Realm, he would still arrange such a formation.
But operating the purification formation requires the consumption of black stones.
Compared with the defensive formation, the purification formation consumes much less black stone.
However, the purification formation must be turned on for a long time. Regardless of whether there is danger or not, as long as there are warriors in the formation, it must always be turned on.
If it is turned on for a long time, a lot of black stones will be consumed every day. Over time, it will also be a big expense.
Moreover, as the number of warriors in the Human Alliance increases, the area of Qin Ming City is too small for the warriors to live.
In addition, the energy in the environment is not enough to replenish it.
The energy on the periphery of the Supreme Realm is circulating.
Even if many warriors stay in one place, there is no need to worry about insufficient energy absorption.
Because even if the energy in the air is absorbed, energy from other places will flow in.
However, there is a limit to this.
Once there are too many Half-Step Supreme Realm warriors and Divine Beast Realm warriors in a certain place, this limit is reached.
Then the energy from the air will not have time to rush in, and the energy in the air will slowly become thinner.
Therefore, the Human Alliance cannot expand indefinitely.
If you want to expand, you must need a larger area, build a larger Qinming City, and also build a larger defensive formation.
If the defensive formation is built larger, more black stones will be consumed.
As for ordinary warriors, without enough heroic spirit energy, it will take a long time to break through to the holy beast realm.
Before breaking through to the Holy Beast Realm, it would be difficult for them to help him.
You can't mine a lot of black stone, and you can't do things for the alliance.
At most they do some chores.
To do chores, you don't need too many warriors, a small number of warriors are enough.
Therefore, letting too many warriors join the alliance at one time will not be beneficial to the alliance, but will cause considerable harm.
