A blackhole is tamed by comparison to places and landscapes that the dimensional portals and spatial rifts could connect Earth to, and they can only be closed by a Player with high mastery of Spatial Magic or similar.
Otherwise, dimensional portals and spatial rifts could only be sealed off. But sealing them off is making them more or less a ticking timebomb.
While I do have the means and methods to close off those portals and rifts, I doubt I can to all of them by myself, and frankly, I do not want to. As long as the places they connected to are not instant death to anyone crossing over, there are plenty of resources and things to acquire from the other side.
Things that can benefit Earth and her interest greatly, and quite a lot of people have used that to their advantage, acquiring incredible Wealth, Fames and Prestige.
Just remember those assholes who have caused so many of my friends to die so meaninglessly makes my blood boil. I channel my rage into the task at hands, allowing me to absorb all the spiritual energies within the room and contain it within my body.
I begin to exert my will in order to control the spiritual energies, and the moment that I have sufficient control, I condense them and form a Spiritual Core. It is similar to a Magic Core that have formed days prior.
And like the Magic Core, the Spiritual Core is also Unranked. Or of the Zeroth Circle. Not even the First Circle yet. And reaching the Tenth Circle is the goal of all Mages or Spiritualist.
I cannot make use of my Spiritual Power in any meaningful ways until it reaches the First Circle. To do so, I have to form a ring around the Spiritual Core using Spiritual Energy within me.
Forming the first ring is easy for me, and it doesn't take more than an hour unlike the first time around, which takes months. Once that is done, a Spiritual Aura manifest around me, and it is similar to raging flames, shielding me.
I condense the aura to make it stronger and less wild. I would need to mold it and shape it to increase my control and efficiency. However, that can be done later since I should also reach the First Circle of Magical Power as well.
Before I do so, I fix up the Headquarter, as the vines are becoming more and more aggressive. And like I have said, as long as I have money, it will never get into my room and to me.
Magic Core requires ring to be form from Mana. My Mana is miniscule due to my Intelligence attribute as well as my class. I am not a Spellcaster or any variation of that class, as such, I do not gain any kind of boosts or benefits.
However, such disadvantages can be rendered moot with unlimited supply of Mana Crystals. Not quite unlimited, but with my current Wealth, I can reach Third or maybe Fourth Circle of Magic. The problem is time.
After two hours of absorbing and condensing mana, I manage to create the first ring around my Magic Core. And it is extremely exhausting. To create another ring would take me a whole day since the core is not ringless anymore.
Same with Spiritual Core. Since the tasks are done, I take a rest while filling my stomach with foods.
