Thinking of this, Su Xiao secretly breathed a sigh of relief. It seems that the 'technologically advanced' label in the world's introduction refers to advanced biotechnology.
It makes sense. After wandering in space for so many years, if the Kara Aliens developed thermal weapon technology, they would lack materials. But biotechnology is different; as long as there's a living organism, research can proceed.
When Su Xiao battled the enemy Ruler, the opponent was a Kara Alien. If the Kara Aliens had developed thermal weapon technology, the Ruler's outfit might be similar to an Iron-blooded Warrior, and not just relying on spiritual power to fight.
The Human Alliance used a nuclear bomb to stun the Kara Aliens. If the Kara Aliens' thermal weapon technology was truly advanced and ahead of Earth's, intercepting a nuclear bomb would be easy.
