They think the earth is a lamb to be slaughtered.
Lu Chen looked at the purple crystal in his hand - Spirit Crystal. One gram of energy is equivalent to ten tons of TNT.
He didn't choose to go it alone.
He handed over the spiritual crystal to the state.
Three days later, Dongfeng Express was ready to go.
Seven days later, the spirit crystal energy conversion system was launched.
