(TL: This is bonus chapter #5 for October. Enjoy! And thanks for the Patreon support!)
Aziz was seriously injured so Sheyan naturally could not leave him alone. If someone like a thief appeared and attacked him, Aziz might die. Sheyan of course couldn't let that happen - at least not while their interests were aligned.
Fortunately, Aziz's injuries had healed very quickly, mainly because the MIB and the US Army provided some technologically-advanced healing items, ie. elastic medical coagulation bandages, BCW adrenaline injections, high-energy antibiotics, high-calorie food, and even used Gamma Knives to stop his bleeding. All these things were readily available in the medical vehicle. Of course, they could not be brought out from this world.
