There's no denying that, regardless of the different intelligent life forms and the varying levels of civilization, the basic instincts of life remain consistent.
The Anan Civilization, when facing a life-or-death crisis, can swiftly abandon everything else.
However, such decisiveness is partly related to the characteristics of the Anan Civilization itself, with which Shen Shi is not familiar. After all, in the distant future three thousand years from now, the Anan Civilization has already perished in this pillage, yet its basic traits he understands.
The consciousness carrier of each individual within the civilization forms a massive "civilization brain," thereby abandoning personal emotions in favor of the greatest common interest.
Thus, the choice of the Anan Civilization at this moment was no surprise to Shen Shi.
And this, likewise, provided a reason to interfere.
