67 7 sins almost gathered (1/2)

”Rei chan.” Merlin said as she saw Rei wake up.

”Mn?” Rei replied whilst rubbing his eyes with his small hands. Some of the servants saw this and felt their hearts beat from how cute Rei acted, they just wanted to pick him up and cuddle him. However, if Rei were to know of what they though, he would surely curse out once more at his body.

”Your dad has gone to look for a giant to join us, so he won't be here for a while is that ok?” Merlin asked as she looked at Rei who is currently stretching his tiny body.

”Un it ok.” Rei said in his childish voice while he finished stretching.

”You'll stay with me near my lab for a while is that ok?” She asked as they reached her tower.

Rei nodded as he felt his energy reserves.

'Che with this amount I can't even summon out more than 3 swords before I faint. And they're not even good swords either.' Rei thought as Merlin carried him to the lab.

'Ah when can I use transformation magic again!!!' Rei mentally cried out feeling the down sides of his current body.

[Host be patient. Your body must fully develop first before your magic reserves grow. And also, your transformation magic needs a lot more mana since you are actively changing your body structure. The only reason you could use it straight away last time was because your reserves and body had already been tempered to a large degree allowing you transformation without much drain.]

'Haaaaa....So I'm stuck with this for quite a while then?'

[Indeed.]

'I guess i'll just do theory study with Merlin for now then...' Rei thought as he shuffled out of Merlin's hug and crawled onto the lab table.

”Ohya? So eager.” Merlin said as she handed Rei a book on seals.

”Rei chan, would this do?” Merlin asked.

”Un!” Rei nodded while he flipped through the book.

Merlin set up a small barrier so that he won't fall just in case and started to work on her own experiments.

Rei could see from the book that a lot of the seals in here had more uses than he could have though of. From ones to keep the appearance of someone till they die, to ones which allow the extraction of someone's soul.

Rei started to immerse himself in the book slowly increasing his understanding of seals.

Merlin on the other hand watched Rei study the seals with such intensity that Rei started to swing his little legs back and forth while reading.

'Cute...' Merlin thought before going back to her experiments. She had started to develop more spells for each of the elements so that she can teach it Rei for countering against the demons and goddess clans.

This carried on for a few months. Which Rei started to get a more uncomfortable feeling in his mouth. He had tried to use his tongue to relieve the pain. Checking in the mirror, Rei could see that his fangs are starting to grow out.

'Hmm....This isn't good. Soon I'll need to feed again. And I'm pretty sure that it would be bad if I turned someone in the castle into a vampire.' Rei though as he walked away from the mirror.

'Wait can't I just ingest some blood?' Rei thought as he slapped himself on the forehead.

'Haaa, I'll ask Merlin for it when it happens.'

Plodding back to the lab, Rei was about to immerse himself back into the book of seals when the ground shook. Quickly looking out the window, Rei could see Diane the giant that Meliodas went to find.

Turning around to Merlin, Rei gestured out the window.

”Rei chan? You want to see the giant and your dad?” Merlin asked as she also looked out the window.

Rei nodded as he started to climb onto the table Merlin was at. Grabbing Rei before he could fall, Merlin then flew towards Diane and Meliodas with Rei in her arms.

”Captin welcome back.” Merlin said as she landed near them.

”Yo! This is Diane, a new member. And Diane, this is Merlin also a member of the 7 sins.” Meliodas introduced Diane and Merlin to each other.

”Oh and the kid here is my son.” Meliodas said not forgetting Rei.

”EEHHHH!!! Meliodas you have a wife and kid!!” Diane said heartbroken.

”Nope I don't have a wife and Rei isn't my biological son.” Meliodas said picking Rei up from Merlin.
