Ariana put the last batch of samples into the thermal cycler, closed the lid, pressed the switch, and it took dozens of minutes for DNA replication to increase in value, during which time she could clean up the messy workbench.

Extracting clues from the dirt was not an easy task, Ariana took more than 600 samples from the dirt, but in the end, they were all from soil insects, various plants, and some messy man-made objects, and Omega found no suspicious traces.

The girl uncovered the plate with a plastic sheet, underneath the plastic sheeting was a withered head and a pitch-black femur, that is, the thigh bone, which was given to her by Lu Xun, according to Lu Xun, which he and the heavy artillery had found during the graveyard vigil last night, and if nothing else, the two remains should have come from the owner of the tomb, Howard Hughes.

DNA tests confirmed this, and Ariana extracted a small amount of DNA from the remains for Omega to compare, and Omega said there was a more than 97 percent chance that it was Howard Hughes' skull and leg bones.

Anna put on plastic gloves and a mask, and straightened the skull on the plate, which had been buried underground for a long time, and was already highly decomposed, with fat, cartilage, and neuromuscular organic matter decomposed, leaving only some of the old bark-like dead skin clinging to the skull, covered with dirt and weeds.

The girl stared at the two eye holes in the skull, the eyeballs were the same as the brain, and these complex, fluid-filled structures were the first to decay, so that the head was left with only two black holes.

She used a fine-bristled brush to clean the dirt on Howard Hughes's skull, and from time to time bugs would crawl out of the cracks in the skull, it was clear that the head had been buried underground for so many years, and there were already creatures in the cranial cavity to make nests.

Lu Xun found only the skull and leg bones in the cemetery, and the sternum, limbs, and sacrum were missing.

Ariana speculated that this was the part that the tomb robbers accidentally left behind when carrying and moving the corpse, and the part that connects the spine to the skull is the atlas vertebrae and the pivotal vertebrae, which are very fragile structures, and when they are fully decayed, they will break and disconnect at the slightest touch, and the tomb robbers will break the spine of the corpse when moving the corpse, so the head will be left behind.

"Anna?" Omega appeared on the computer screen, a little curious, "Did you find anything?" ”

"Nope."

Ariana shook her head, took a step back, and took off her mask and gloves.

"I'm going to get this head checked."

She leaned over and opened the door of the cabinet under the workbench, and pulled out a large box from inside, and the girl reached out and touched it, and felt for a handful...... Hatchet.

Ariana flipped the axe in her hand, probably not satisfied, and casually threw the axe aside, and pulled out an electric drill from the box.

The girl also threw the electric drill aside, touched it again, and took out a huge pig-killing knife, which was cold and shining.

Ariana pulled out a wrench, a hammer, and a screwdriver from the box, these tools seemed to be used for carpentry work at all, Omega looked sweaty on the side, it was Ariana, Zhao Gao called her Doctor Chainsaw when she was still there, she was the most violent person in the safe zone, often used tools to dissect the corpses of hunters in the underground dissection room, she was more like a carpenter and butcher than a doctor.

Ariana finally found a handsaw and began to crunch and squeak at the skull in the plate.

That ferocity really looks like a pervert.

Howard Hughes's poor skull was slaughtered like this, and if this head could speak, it would probably be scolding his mother...... This female pervert actually pulled a saw over her head, and the fine white powder fell on the plate.

The skull is very hard and spherical, and it is difficult to focus on ordinary sharp weapons, so under normal circumstances, a saw is used for craniotomy, but doctors use a fine wire saw when performing craniotomy, and Ariana has a rough carpenter's hand saw.

Ariana sliced open Howard Hughes's head lengthwise, which split in half like a watermelon, and the girl took a step back the moment the skull split, because everything hidden in the cranial cavity escaped...... Howard Hughes's head was indeed occupied by some small animals, most of them were insects who were afraid of light and shade, so the moment the skull opened, the strong light came in, and the insects scattered and fled.

Ariana put the handsaw aside, put on gloves, and began to clean Howard Hughes's cranial cavity.

The inside of the skull was basically empty, and the cerebellum had long since been gnawed clean, and the inner walls of the skull were covered with spongy dirt and unknown mucus...... It was probably some kind of insect nest, and the girl used a brush to clean the dirt, and the worms that crawled out landed on the plate, which Anna grabbed and threw into the beaker.

"It's disgusting." Omega said.

"That's how it happens when people die." Ariana said lightly, "If the corpse is not cremated, the corpse will be buried in the ground, the organic matter will decay rapidly, the cells and tissues will be decomposed by bacteria, and attract a large number of scavengers, these corpse insects will burrow around the corpse and make nests everywhere." ”

"That's better cremated." "The thought of these bugs burrowing around your body makes your scalp tingle. ”

"But that's the law of nature." Anna said, "When any creature dies, it decays, is eaten by other creatures, and finally returns to dust...... Princess, do you know about whale falls? ”

"Whale fall?"

"Whales are the largest creatures in the ocean, and they eat a lot of food during their lifetime, but when they die, the carcass sinks to the bottom of the sea." "The carcass of a whale will bring life to the entire ocean, the microorganisms that decompose the carcass of a whale will attract a lot of mayfly creatures, and plankton will attract fish, and fish will attract other predators, and countless creatures will depend on the carcass of a whale to survive, which is called whale fall...... The whale falls, and all things are born. ”

Omega nodded, "Sounds like a cycle. ”

"The ecosphere itself is a cycle, where organic matter is broken down into inorganic salts, and inorganic elements are synthesized into organic matter." "Neither humans nor hunters are in this cycle, and no matter how powerful a hunter is, he or she cannot violate the most basic ecological laws." ”

"So in the end, is it nature itself that is the most powerful?" Omega laughs.

Anna was stunned for a moment, then smiled and nodded.

"That's right."

There was a sudden sound of "buzz-" behind him, and Ariana's hand moved.

Omega looked up.

"The PCR of the last batch of samples has been completed."
