Million rebirth (part 1)

The girl haft bady fell to the ground and was not moving even an inch, when i noticed that i immediately go to Kiara and tried to cover the wound but she said, 'Please kill me and wait for me to revive again!' the thought of that made me uncomfortable but her heart was pierced and can regenerate but the pain is not to be laughed about, but i then thought about one of the members that left she said, 'If you guys ever need fast and painless way to treat an incurable wound or virus you can use my medicine in the lab that should work and let your natural healing do the work, if both of you need too since you are immortals!' when i realize that i quickly lift Kiara and instantly teleported to the lab, when i got there it was a mess they probably didn't get to clean the place. I then take the medicine and feed it to Kiara in a few seconds she calm down and was sleeping a lot more peacefully, it made me happy to look at her like this and made me think that i should not leave her alone for too long since idk what she might find or fight again, 'What a trouble maker!'that what i said in my mind, a few days past by Kiara finally woke up and was quite energetic she then go out wonder around and of course i was with her but when she turn left she was gone, i panic but she then jump at my back because of that i fell face flat i then scolded her many time at that time, and we then visited one of the place we sometimes go with all of the members, the place still has the same smell as back then and when we were about to live that place a figure come in front of Kiara it was the same girl back then, i thought to myself "How!?" i quickly push Kiara back but the girl pass through me and give Kiara a shapeless object that enters inside of her after i saw that i tried to grab it before it completely enters but the girl suddenly push me back and the push was so strong that i clash with the walls but i quickly recovered at that time too the shapeless object is completely inside of Kiara but she didn't show any uncomfortable feeling or pain so i ignore it for now and quickly got back to base!
