Led by the knight, Number One once again went to the laboratory that gave her a terrifying feeling, the smell of the air reminded her of the last painful experience here, and there seemed to be some dark red blood stains on the ground that made her heart tremble, but as a test subject, she was powerless to resist, and was once again placed on the operating table.

"This time we will definitely succeed!"

Several researchers gathered around No. 1 to observe, and one of them had a fanatical look in his eyes, today's experiment was about whether the results of their research could be displayed in front of the Emperor's eyes, and if not, the research team would be disbanded, this was the last chance.

No. 1 nervously watched as the needle tube got closer and closer to his arm, until a sharp pain came, the feeling of skin being punctured appeared again, and the blood of the demon in the needle began to inject into her blood vessels, the same pain as last time, making No. 1 constantly make the sound of inhaling cold air, but because the strange energy in her body did not directly show signs of imminent death this time, but could only endure waves of pain.

"It hurts, it hurts!"

One's screams came out of her mouth, constantly echoing inside the laboratory, from the gap in the iron door to the outside world, no one could understand her current pain, although she had not experienced death, but at this time she also wished to die immediately to get rid of such pain.

"Subject is dying."

The researcher who had been observing No. 1 said that No. 1's face was now bruised, and his arm was abnormally twisted, and he was on the verge of death.

"Leave it alone, keep injecting."

The senior researcher stared coldly at the half of the blood left in the needle, this is the last chance, it is better to give it a fight than to give up, anyway, it is common to kill the test subject, these researchers are also cold-blooded, and after seeing the order from their superiors, they accelerated the injection.

Number One only felt that her consciousness was getting more and more blurred, and the feeling of pain was about to disappear, she was very tired, and she wanted to sleep like this, but she felt that she would never wake up after sleeping like this, and Number two, Number Three, Isabella, her few friends who cared about her would never see her again, so she was still struggling.

"One, one! I know you're in there, no matter what happens, you have to hold on, I'm a useless friend, I can't help you, but even if it's for me, you have to survive, I don't allow you to die! ”

Just when No. 1 was about to hold on, a call came from outside the research room, the sturdy iron door was slammed, and Isabella's anxious voice sounded, with a trace of worry and unwillingness in her words, as if she felt very remorseful for not being able to help No. 1.

"Princess..."

No. 1 heard Isabella's voice and the corners of her eyes were instantly wet with tears, she couldn't find any advantages in herself that could make the little princess care, but the other party cared about herself so much, if she died, it would definitely disappoint Isabella, so she couldn't die, she had to live.

A strong desire to survive erupted in No. 1's body, and at the same time, the blue chip on the back of her hand also emitted a dazzling light, and the transferred strange energy exploded in full force, suppressing all the demon blood in No. 1's vein, causing it to merge with No. 1's blood.

The researchers in the laboratory were all surprised to see this strange scene, No. 1 had truly fused the blood of the demon at this time, and a powerful feeling was born from the bottom of her heart, and she immediately broke free from the shackles on the operating table and ran towards the iron gate that separated her from the princess.

At the moment of opening the door, No. 1 stumbled and almost fell, but a soft body hugged her, and when she looked up, it was Isabella, and the little princess also showed a surprised expression when she ran out, and the arm holding her was tighter, at this moment something took root in No. 1's heart, she felt that she had died once, and this rebirth might be to meet the person in front of her again.

The commotion caused by No. 1 was quickly suppressed by the knights, even though she had the strength to surpass normal people at this time, but she still obediently returned to the room, and the researchers were eager to report that their research was successful, and the princess was also protected by the knights and taken away, only saying that she would come back to see her next time.

"One, are you alright?"

No. 2, who had been waiting anxiously in the room, was relieved to see No. 1 being sent back, but the worry in his eyes was still there, and his palm tightly pulled No. 1's hand, only in this way could he feel her presence.

"I'm fine."

One didn't say anything about the danger of the experiment, but just said with the same smile as usual, she didn't want No. 2 and No. 3 to worry, and at the same time secretly decided that she would have to go to this kind of experiment herself in the future, and she couldn't let these two people experience such danger.

"Your eyes?"

Surprise and fear suddenly appeared on No. 2's face, and she hurriedly pulled No. 1 to the mirror, and pushed No. 3, who was looking in the mirror, away, so that No. 1 could see her current appearance clearly.

Number One looked in the mirror, and she suddenly found that her eyes had changed, and her pupils were still the same red as before, but the whites of her eyes were all blackened, looking weird and terrifying.

"Number one, do you hurt? It's all my fault, I was the one who was going to be caught doing the experiment, I'm sorry..."

Number Two was about to cry when she saw No. 1 in distress, she still remembered that it was No. 1 who stepped forward to protect her when she did the experiment for the first time, otherwise it would probably be herself who became like this now.

"I, I'm fine, it doesn't hurt, it's nothing."

Number One was also very frightened of the change in his eyes, but there was an indifferent smile on his face, and to be honest, there was no pain in his eyes, and he comforted Number Two in turn.

After that, the small cell returned to its usual routine, No. 2 and No. 3 often quarreled, and No. 1 waited silently for Isabella to come and chat with her secretly, but everyone didn't know that there was always a stranger's voice in her head, it was a man named Tamos, who said something that No. 1 didn't understand, but she didn't care, it was already a blessing for her to survive.

A year has passed in a blink of an eye, and in this year, No. 1 has undergone two more experiments, although it is dangerous, but because her physique and desire to survive have endured, she herself does not know what happened, but she is already a very valuable experimental subject in the researcher, because she already has three kinds of demon blood in her body completely fused, and she is the most successful experimental subject for transplanting demon hands.
