Once Du Gang stopped absorbing the Red Crystal, the team transporting the materials immediately slowed down.
Yao Zhenguo quickly rushed in, asking, "What's wrong?"
Shaking his head, Du Gang replied, "I've reached my power limits. The Red Crystal can no longer enhance me. Let them stop!"
"What?"
Startled, Yao Zhenguo hurriedly suggested, "If Red Crystals can't enhance you, we still have Orange Crystals, Yellow Crystals... If all else fails, we'll sell the spaceship and get you Purple Crystals..."
The E-class three-star spaceship was originally Du Gang's spoils of war. He had no objection to its selling for Purple Crystals, which were to be Du Gang's.
Public is public, private is private. This kind of spoils of war belonged to Du Gang. Yao Zhenguo wouldn't use moral blackmail to force Du Gang to hand them over. It's meaningless and unattractive.
Waving his hand, Du Gang rejected the offer, "No need, let them all stop. What I mean is, the crystals can no longer enhance my power!"
