In the past, the living space for the heroic spirits was very narrow.
But now it's different.
After the brain space is expanded, the heroic spirits can not only live in it, but also train in it.
They trained inside and their actual combat strength became stronger and stronger.
This time they fought against the poison demons, and their performance was very good.
It can be seen that they usually train very seriously.
The heroic spirits can help him do many things.
For example, in this city, Qin Ming and Qin Xixuan went in to look for the black stone. When should they go?
There are so many heroic spirits that it only takes an hour to search through all the boxes and cabinets inside.
All resources and treasures were put away and placed in the mind space.
Together with the corpse of the half-step supreme poison demon.
If in the past, Qin Ming would have been very happy if he had obtained the corpse of a half-step supreme poison demon.
But not anymore.
Now that he has a lot of space in his mind, a half-step supreme corpse will have little impact on him.
However, the corpse of a half-step supreme poison demon can be corrupted into a lot of ordinary energy.
Soon, the heroic spirits counted the number of black stones they obtained this time. The total was worth three million pieces of ninth-grade black stones.
Three million pieces of ninth-grade black stone!
This is a large number, equivalent to a heroic spirit that can use six ninth-grade black stones.
Although it is not a lot, it is equivalent to the amount mined by the Human Alliance in half a year.
Of course, not all are ninth-grade black stones, but only ninth-grade black stones are used for calculation.
There are many other grades of black stone, all of which are converted into ninth grade black stone.
Even though such a large poisonous demon branch has only obtained a few ninth-grade black stones.
I think three million ninth-grade black stones are very few.
In fact, three million pieces of ninth-grade black stone is a lot.
You must know that even if it is a ninth-grade black stone vein, not all the black stones mined are ninth-grade black stone.
On the contrary, most of the ninth-grade black stone veins and most of the black stones mined are eighth-grade and seventh-grade.
On the contrary, the ninth grade is in the minority.
Among the ten black stones, one is grade nine, which is already very good.
The ninth-grade black stone veins are not so easy to mine.
The rocks in the ninth-grade black stone veins are very hard, and only powerful warriors can mine them with all their strength.
Mining a piece of black stone requires a lot of effort.
Of course, if you are a half-step Supreme Realm expert, it will be easier to mine the ninth-grade black stone veins.
But it's just easier.
It’s also very laborious.
Therefore, even if it takes half a year, it may not be possible to mine three million pieces of ninth-grade black stone.
Three million ninth-grade black stones are enough for a warrior in the middle half-step of the supreme realm to practice to the late half-step of the supreme realm.
It's a pity that for a half-step Supreme Realm expert to break through the martial arts realm, he not only needs black stones, but also pills.
Using the black stone to practice, the martial arts realm improves very slowly. It may take hundreds or even thousands of years to achieve a breakthrough.
Even if you take pills, it will be difficult to break through in a short period of time.
Just like the current half-step Supreme Realm warriors in the Human Alliance, even if they have sufficient Rule Pills, they are still Rule Pills of perfect quality.
None of them have broken through to the mid-level supreme realm in martial arts.
It is very difficult to break through even a small realm.
However, as long as you break through a small level in the martial arts realm, your strength will be greatly improved.
Qin Ming was very satisfied with getting so many black stones.
He didn't know how much heroic spirit energy it would take to break through to the peak of the half-step Supreme Realm in his martial arts realm.
