Nuonuo called out twice, but didn't make any sound; instead, it was pure data information. This was how it always communicated with Su Yu.
With Nuonuo's current Fourth Rank strength, this information instantly transmitted over ten thousand kilometers, even reaching deep into the Earth Core.
Logically, Su Yu should definitely hear it; however, Nuonuo did not receive any response.
After a while, it called out again, but still no response, and suddenly felt a bit panicked.
It hurriedly tried to sense Su Yu's location carefully.
As Su Yu's Mechanical Apostle, it was closely connected to Su Yu, and with a slight sensing, it could detect Su Yu's general state and position.
But at this moment, it couldn't sense anything! It was as if Su Yu never existed from the beginning!
Its heart sank, and it quickly merged its 30 avatars worldwide into one, then drilled underground.
Soon, it arrived at the Earth Core and started searching.
