In the evening, the basement of the Yan family brothers' villa dormitory.

The brothers walked into the lab in their lounge clothes. At this time, Gu Xiaoyi had already been cleaned, his whole body* and his limbs were locked and buckled on a planing table. With your eyes closed, lie there.

The brothers walked over and stood in front of the planing table, admiring the youthful, fresh and beautiful test subject.

"This is a very good test subject, and my brother is blessed this time. Yan Feilong put on his gloves and stroked the elastic test subject in front of him.

Yan Tenglong's eyes were cold, but he couldn't hide the excited and satisfied light inside, and he also stroked this beautiful experimental subject.

Yan Feilong took a small glass bottle from the side, shook it at Gu Xiaoyi's shortcomings, and then looked at the experimental subject with his eyes closed in an evil manner, and slowly opened his eyes after a few seconds.

"Hi baby, welcome to our world. Yan Feilong smiled at the temptation of the devil.

Gu Xiaoyi was stunned for more than ten seconds before he reacted, and said in fear: "Fly, Feilong senior." Hindsight, he realized that his limbs were fixed to a table that resembled a bed. Frightened, he began to struggle: "Senior Feilong, I was wrong, please let me go, let me go." Frightened, his eyes fell out.

"Shh Baby, your Gu family has agreed to give you to our brother to enjoy in order to protect yourself. Yan Feilong said gently: "So, you have to be obedient now and make a useful tool." Don't worry, we will be gentle and won't let you hurt. Yan Feilong's voice was full of soothing and charming, and his gloved fingers pressed and wandered on the girl's lips, like a lover talking love words, making Gu Xiaoyi slowly stop struggling.

"That's good!" Yan Feilong said, then turned around and picked up a needle that had been prepared a long time ago from the shelf behind him, and slowly pushed the liquid inside into the blood vessels of the test subject.

Gu Xiaoyi's eyes widened, and there was a dead ash and despair inside, and she no longer struggled.

After the liquid pushed through their bodies, the brothers waited about 20 seconds before they started moving. A prepared infusion needle was inserted into the subject's blood vessels, and on the other side was a bright red blood bag.

The two of them each had a scalpel, and carefully cut through the beautiful skin of the test subject, who was very awake but did not feel pain. The red blood slowly overflowed with the incision, and it was extremely gorgeous against the white skin.

"It's so beautiful!" Yan Feilong praised.

"Hmm. Yan Tenglong nodded, and his subordinates did not stop, and began to slowly explore the living test subject. With the assistance of high-end instruments, the operation of all organs of the subject was carefully observed, moved, observed, and then carefully put back in place. That attitude is like treating a diluted treasure.

Under the gradual exploration of the brothers, the test subject was disassembled little by little, but it operated normally, and did not affect life at all. The picture is weird and breathtaking!

The black killer guards who were hidden around the brothers were unsteady and showed their figures.

"If you can't see it, go out. It's safe here, and you don't have to follow you. Yan Teng's head is not on the stage, and he said coldly.

"Mr. confessed that he would guard the two princes 24 hours a day. A man in black bowed his head respectfully.

Yan Tenglong glanced coldly at a few black killer guards, didn't say anything more, and continued to disassemble and observe the living test subjects.

The subject could no longer stand the sober perception that his body was stimulated by a little dissection, and he had passed out.

"Brother, let's stop here today, and leave my brain for tomorrow. After a while, Yan Feilong said.

"Hmm. Stitch it up. Yan Tenglong nodded, began to put those organs back in place, and then began to stitch up the wound step by step. The subject was injected with a drug to keep it alive.

"Keep it guarded, don't let it be in any danger to its life, this is the treasure of the dragon. Yan Feilong put down the scalpel, took off his gloves, and said to the black-clothed man standing in the distance.

"Yes, young master. "Humanity in black. Looking at the experimental table, the man who had been reassembled and stitched up, breathed a sigh of relief. Although the subject was covered in suture wounds, it was much more comfortable than jumping into the picture where the organs were exposed and still working normally.

The brothers walked into the lab's private bathroom, took off their loungeclothes that weren't stained at all, turned on the shower, and stood underneath to wash off the smell of blood.

The two looked at each other face to face, one evil and the other cold, looking at each other through the water curtain, with a deep strange admiration in their eyes. Their eyes were intertwined, as if forming an invisible bond, entwining each other's hearts and minds, and sending them tired and compassionate.

Suddenly, the two hugged each other at the same time, their lips touched fiercely, and the heat made each other tremble physically and mentally, and their souls screamed. They entangle each other's lips and tongues, gnaw at each other's elastic skin, tear at each other like two wild beasts, as if they want to swallow each other into their bellies, disassemble and taste. They are full of interest in this game, never get tired of attacking and plundering each other, longing, trembling, crazy, and never getting tired of it!

After thinking that a century later, after two muffled grunts, they used each other weakly, panting and breathing.

The curtain of water still poured out, washing over their youthful bodies, and the source of power that had just been released flowed down with the water, leaving no trace.

The two hugged each other again, their lips and tongues entangled for a long time, before they turned off the shower, wiped off the water droplets, put on their bathrobes, took each other's hands, and walked out of the laboratory.

Back in the bedroom, both brothers were in good spirits. Sitting on the sofa together, leaning on each other, each dealing with the Yan family's affairs and the demon soul things that they are responsible for, complementing each other's influences.

In the days that followed, the two brothers would do the same every day, dealing with affairs in the morning, going to the 5th floor of the library to read books in the afternoon, entering the laboratory in the evening to dissect the living test subject, and then going into the bathroom together to take a bath, rinse off the blood on their bodies, and feel tired and sad by the way. However, due to the mentality of the two brothers who are strong, they have never made it to the end, nor have they discussed the question of who pressed whom again, so they have been living in a regular way. However, they both know that each other's crazy desire to have each other, which has been endured to the limit, is about to break through the cage of their sanity, and they are crazy to tear each other into pieces and eat each other!

Until, ushered in their 18th birthday.
