In the end, Gu Shanhai decided not to bother looking elsewhere and just combined his breakthrough Divine Skills.
After all that effort, half a month had passed, and he had barely managed to create a prototype.
However, it had just failed after dropping about ten thousand meters.
"It works but is prone to failure..."
After checking, Gu Shanhai also found the reason for the failure—his strength had suddenly increased, so the data was no longer accurate and it went directly out of operation.
"It's okay, it's just a prototype. I'll fix it."
Gu Shanhai muttered as he worked, then noticed a lot of tentacle-like roots on his face twitching as Rein approached.
"Teacher~" Rein's voice was quite loud.
"Don't yell so loud, I can hear you!" Gu Shanhai responded, reflecting on the volume of Rein's shout which was visually evident.
He had grown larger in size, not deaf.
"What do you need?" Gu Shanhai asked again.
