The same things happened not only on Aslan and with Wang Zheng, but also in other places. No terrorist group had ever dared to be so arrogant!
In the Arbiter Republic.
Mars and Olivios were undergoing special training in the Iron and Steel College. Students could choose to rest or go back to college after SIG. Mars had graduated, but Olivios didn't stay in Elite Academy X. He had to at least comprehend the inner universe before going back. He had no combat power now at all.
It was better for him to be back in the Iron and Steel College to take advantage of the time to go over the SIG. It would be much better for absorption of what he had learnt there than to waste his time away. Many people had the same plan.
