Chapter 421: Accelerating Space Layer

In ten days, all the personnel engaged in resource gathering had returned.

Lin Yun had received a total of over 690 million Spirit Crystals, a truly terrifying amount.

This was not only because Lin Yun had once again sent out forty teams to collect resources in full force, but also because some resources were collected from large planets such as Mars, Jupiter, and Saturn.

In particular, a special energy was discovered on Jupiter, which consists of many gases. Those special energies alone sold for over 110 million Spirit Crystals.

Lin Yun used 85 percent of the price to buy four robots with the strength of the early Stellar Nebula Realm martial artists from Tong Luo. He spent 340 million Spirit Crystals.

They were respectively named Cloud Two, Cloud Three, Cloud Four, and Cloud Five.

Lin Yun planned to leave Cloud Three, Cloud Four, and Cloud Five on Earth, and he left with Cloud One and Cloud Two.
