Luo Yuan stood in front of the ninth-level insect swarm, holding a scrapped mecha core in his hand - he had just pulled out the last energy from this pile of junk.
"Please, just do it one last time!"
The Alliance Marshal was kneeling in the ruins, his eyes bloodshot. Luo Yuan weighed the core fragments, and suddenly kicked away the S-class mecha next to him. In the cockpit, the strongest man in the Federation, known as the Immortal God of War, was holding his thigh and crying.
