“Masters, Mr. Kostas and Ms. Quinn are here!” Kenway reported behind the door while Mercer was explaining. Kenway tacitly informed and not asked if he should let them in or not. If Mercer didn’t want them inside the lab, they would greet them outside. If he wanted, he would say so, and Kenway wouldn’t offend the other party.

“Welcome them in,” Mercer answered and they went to greet them inside.

Mercer, Malcolm, and Merlin went to the door and brought them to the lab, in the meantime Miles was observing the autopsy. Roger dissected the body masterfully in a few seconds while Adam and Evelyn were watching from the side.

The alien had a similar build to humans. There were lungs inside the ribs and a heart three times bigger than a human’s. The lungs were also bigger and had a more efficient circulation system allowing aliens to intake oxygen and pump the blood without a delay. With it, their larger and extra muscles could be supplied with oxygen a lot faster.

Muscles and bones were perfect as well. They were built to move at maximum efficiency, allowing these creatures to move at high speeds.

Human limits couldn't be overcome by stronger muscles only. As strengthening serum was working on the body, it was also strengthening smooth muscles like lungs and of course the heart. Although it wasn’t as good as how these aliens had, humans were evolving into what these aliens were with each serum.

For example, the fourth strengthening serum not only destroyed and healed muscles but also bones, veins, and the skin. It was destroyed as a whole before reforged. Human anatomy wasn’t built to do high-speed runs like a cheetah, but more evolved to use tools. But this alien had even a spine slightly allowing it to run faster.

As Miles was pondering, Kostas and Quinn arrived with the Cross trio.

“Hey Miles.”

“Hey, kiddo.”

Both greeted Miles at the same time, and Miles also rose from his seat and greeted them.

“I have bad news, Mercer.” Kostas delved into the conversation after they sat down without waiting for them to explain what was going on. Miles, at first thought this sly fox was there to use the connection between Merlin and Quinn to learn more about aliens and the race but turned out he was there for another reason.

“Other families are mad since your grandkid snatched the AI necklace and destroyed it, while your family also owned the body.” He nodded towards Miles as he said.

“If it wasn’t for my grandson, we wouldn’t learn anything about their race!” Mercer bellowed angrily. “In those short seconds before self-explosion, my grandson’s AI learned vital things! Tell those families they should be thankful that my grandson was there, otherwise, we wouldn’t learn a shit!

Destroying the AI, don’t make me laugh, all of our wristwatches would do the same as soon as we are dead. They know it too!”

“I know, Mercer, they know too. This is just an excuse. Your family is getting all the good stuff lately, so other families are getting nervous. There are many schemes going behind the curtains, you should be careful.” Kostas warned tensely. They were together in this, so the more prosperous the Cross family got, the more they would benefit from it.

“Let them come! I will show them why despite many targeting us since the creation of Unity, we are still standing.” Mercer showed his indomitable will and rose to his feet. “They finished the autopsy, let’s go.”

When they arrived at the table, Miles was looking at the floating woman in nurse clothes stitching the alien’s body. The nurse’s body was lifelike and she was masterful at using the needle. Roger conducted the autopsy by himself, but he let his ultimate do the stitching.

“Mr. Roger’s ultimate is a work of art. Every time I see her at work, it mesmerizes me once again.” Kostas praised generously.

“Mr. Kostas is too kind. Your Wings of Gods are much better than my ultimate.” Roger laughed heartily as he praised back. Miles looked at the nurse with his eyes burning. ‘So this is an ultimate. They are as magical as Merlin said.’

“What did you find?” Mercer asked.

“Alien’s body, as if, created for battle. Muscles, bones, and organs are all supporting high-speed movements and can repel the shock. Because there are signs of strengthening serum of the F-Series, we cannot say for sure if it is natural or not, but the original body should be a lot better than humans.

This alien trained himself well. The muscle density and elasticity are pretty good. From what Miles told us, the final attack he was using wasn’t an ultimate but a technique. That strong technique can cut E-Tier Hunter in one slash is a common attack among these creatures.

We don’t know why the alien hasn’t shown his ultimate. Maybe it simply didn’t have the ability to create one, since their brains aren’t evolved as much as ours. But they make it up with their bodies for sure. All in all, I can pretty sure confirm Miles’s theory on the slave race helping them with their technology.” Evelyn reported what they found.

“What do you mean you cannot be sure about the original structure because of the F-Series Serum?” Miles asked when all of the pondering.

“Oh, you don’t know yet.” Roger shook his head and explained. “As you know, humans are not able to use serums until they are in Form-Rank, except the monsters like you.” He eyed Miles meaningly.

“You shouldn’t call my son a monster.” Evelyn frowned with a cute pout.

“Whatever.” Roger shrugged and continued, “So only Form-Rank hunters ‘normally’ can use G-Series Strengthening Serums, while only Extol-Rank Hunters can use F-Series Strengthening Serums. So it is pretty rare even in Unity.

F-Tier Serums, like Fourth Serum, change the structure of your body as a whole. Not only muscles but bones, nerves, veins even your marrows change. With each serum, you leave your human identity behind slowly.” Roger explained.

“Have you ever seen an Extol-Rank hunter’s bones?” Evelyn asked. Miles shook his head. Although many people fought that day, Miles never checked their bones. Roger cut open the alien’s arm once again and showed pitch-black bone. At first, whie Miles was observing the autopsy, he thought it was the natural color of the bone, but only then did he understand. “You mean?”

“Most Extol-Rank or higher level humans have black bones.” Roger nodded.
