The effects of the Artificial Gu Vessel were random, and its contents unpredictable. Whatever it produced was normal, and it might even yield nothing for ten days or half a month.
However, Chen Yu knew his luck was pretty good. Using this would let him make the most of the Fairness policy, making it easier for them to obtain Gu insects during the journey and helping them reach their destination.
This Heavenly Tribulation was just as fierce as before. Golden Thunder seemed determined to finish what it had failed to accomplish last time, crashing down in wave after wave like a violent storm, or like huge axes splitting the sky to pieces.
But Chen Yu had seen plenty of storms like this in Heavenly Demon Space. He simply fought the Heavenly Tribulation to his heart's content, then sent it off in satisfaction.
After the last Tribulation Clouds dispersed, Chen Yu looked contentedly at the Gu vessel floating in the air, hoping it would produce something useful this time.
But when he saw the Gu insect, he was once again somewhat speechless.
It was a butterfly-like Gu insect. Its wings seemed to be formed from sunlight, constantly releasing invisible ripples whenever they fluttered.
"What is this one? Bai Buyu, do you know?"
Bai Buyu's face changed drastically when she saw it. "Isn't this the Great Black Heaven Gu? You managed to refine even a Gu insect that has gone extinct? What exactly is that Gu vessel of yours?"
"It's a Gu vessel that uses the Chaos Algorithm. Nothing it produces would be surprising. Is this Great Black Heaven Gu powerful?"
"Extremely powerful. It can indiscriminately strengthen every Gu insect on your side and double their effects. Paired with the Poisonlight Centipede from before, it could make people wish they were dead.
