The device Lin Yu had left behind back then had indeed served its purpose.
The insect race's attack came to a halt just ten kilometers from the central city of the Tarak Civilization.
Yalance knew of humanity because, thousands of years ago, Empress Aliya had sent a human warship into the Minor Universe and told Yalance that humanity and the insect race were currently allies.
After seeing the warning projected across the sky, Yalance forcibly called off the frontline army's advance. However, he did not order the war bugs under his command to retreat. Instead, they continued surrounding the Tarak Civilization's last remaining city, as he needed to ask the Empress how this matter should be handled.
When Aliya learned of this, she was not particularly surprised. She knew that after Lin Yu had entered the insect race's Minor Universe, he had stayed on this planet.
That made everything easy to explain. Most likely, before leaving, Lin Yu had feared that the insect race might one day harm the Tarak Civilization, so he had left behind this Warning Device.
For the insect race, which harvested civilizations throughout the Minor Universe, sparing a single planet was no great matter.
But the key was that in merely a few thousand years, this civilization had risen from a primitive level to the fifth tier. Clearly, before leaving, Lin Yu had left behind more than just that Warning Device. Otherwise, the Tarak Civilization could never have developed so quickly.
Therefore, they could spare this civilization out of respect for humanity, but they absolutely could not allow it to continue developing like this. Otherwise, who could guarantee that the Tarak Civilization would not become a future threat to the insect race within the Minor Universe?
Having made her decision, Aliya issued Yalance her final orders.
