Soren fell silent at those words.
If one asked what the most valuable thing was for a wizard tower.
Then without a doubt, it was solely the tower spirits!
A tower spirit itself possessed combat power above the legend rank, acting as both a top-tier assistant and a supercomputer. For an arcanist, the assistance of a tower spirit allowed him to achieve twice the results with half the effort in his everyday experiments. If Soren let these tower spirits go, the value of the entire arcane tower would instantly be discounted by nearly half at the very least. This kind of loss meant he would only obtain an empty shell, leaving the internal core within to be acquired slowly by his own efforts.
However!
If Soren did not agree to this demand, he would likely be left with no choice but to fight next.
Leaving aside the question of victory or defeat.
If a battle broke out, Soren's losses would also be immense, and any casualties among his people were something he did not wish to see. Moreover, judging by the stance of these tower spirits, if they fought they might defend it to the very last moment with their lives. Even if Soren won, he would only get the shells of five tower spirits. While this would be beneficial for his subsequent research, Soren had already obtained an unactivated combat tower spirit on the fourth floor. Besides, the demigod tower spirit in the war chess demiplane could never leave anyway.
"Your Excellency True God!"
"I wonder what you think of our proposal?"
Tower Spirit 1, leading the group, also seemed a bit nervous. After all, this concerned their fate spanning thousands of years, and they could only gain a new lease on life by heading to the Clockwork Nirvana
