Dimensional Travel in Sparta

"1021, Are you a Spartan from another parallel universe?" Cortana said "Although you have a lot of information, you don't understand many situations. Therefore, in another parallel universe, some things will go differently." "..." Roger couldn't answer. He was indeed a Spartan and wore Mjolnir, but he was not a Spartan from the UNSC world. He was just a time traveler who was dragged to fight by "gods". "Okay, Cortana. 1021 May have his difficulties. Let us deal with this human rebel group first." The Master Chief looked at the group of humans wearing strange equipment that suddenly appeared in front of him and said. "Hahaha, brothers, kill these demons, and this power armor will be ours!" - A certain cannon fodder reincarnation shouted while being watched by five Spartan warriors.
