"You deserve eternal life, dragon, you are no different from before, you are still so self-righteous and have unrealistic illusions."

The familiar and unfamiliar sarcastic voice sounded very suddenly, and the evil dragon, who was immersed in himself, suddenly changed his face, and before he could react, a figure rushed into the operating room.

With the intrusion of this figure, a sharp sound broke through the air, and the researchers in white coats, who had not yet figured out what was going on, all had a throwing knife stuck in their heads, and one by one their eyes widened, and they fell to the ground blindly.

Until the moment they lost consciousness, they didn't believe that they had died in such a daze, and they didn't even have time to generate fear.

At the same time as several researchers in white coats fell to the ground, a figure appeared next to the operating table, and a fake tiger knife in his hand swung up, severing the iron rings that bound the cold man's bloody hands one by one.

"Are you alright?" Helping the indifferent man's bloody hand up from the operating table, Yang Hong asked.

"Thank you for your concern, I'm fine." The indifferent male bloody hand bowed gratefully, if it weren't for Yang Hong's presence, he would almost be used as a test subject.

"Yes, it's you." Standing not far away, the evil dragon who had recovered from his shock looked at Yang Hong who was standing on the edge of the operating table, and exclaimed with surprise and hatred on his face.

"Hehe, it seems that you haven't forgotten me, I really didn't expect that the leader of the evil dragon mercenary group back then had plastic surgery in order to save his life, and hid incognito in the immortal bird organization, which really made me easy to find." Staring at the evil dragon whose appearance was very different from before, Yang Hong sneered mercilessly.

Compared to before, the evil dragon at this moment is much better-looking, but the familiar voice and demeanor are still so obvious.

"Hahaha, God really helps me, it seems that even God is helping me, so that I can kill you with my own hands and avenge my father." Laughing wildly, the evil dragon's face was hideous, still that arrogant and arrogant appearance, as if he had completely eaten Yang Hong, just like at the beginning.

"Your father deserves it, besides, it wasn't me who killed your father, you don't need to say it so righteously." Pouting disdainfully, Yang Hong's eyes were murderous, and he reached out and inserted the fake Tiger Spirit Knife back into the scabbard.

"Don't worry, I won't let you die so easily, I want you to repay a thousand times the death of the strong son back then." Shouting angrily, his mind couldn't help but think of the moment when the strong son was drowned by the explosion, and the strong son still had a smile on his face at that time, that was relief, that was a smile that did not involve Yang Hong.

Thinking of this, Yang Hong's killing intent skyrocketed, and he decisively performed the second transformation of the tiger and leopard at the same time, the ground under his feet trembled suddenly, and at the same time as two footprints appeared, his figure disappeared in place in an instant.

"How is that possible?" Before the exclamation could be fully shouted, Yang Hong's figure had already appeared in front of the evil dragon, and a punch slammed into his stomach.

The sudden blow made the dragon's body shrink into a shrimp shape, its eyes protruded, as if it was about to stare out of its sockets, and a mouthful of blood spurted out of its mouth.

At the moment when the blood spurted out, Yang Hong's figure disappeared in front again, avoiding being spurted by the blood, and appeared behind the evil dragon, kicking him out with a roundabout kick.

"Bump!" The dragon that flew out slammed into the operating table, and under the impact, a needle tube containing red liquid fell beside him.

"Evil dragon, just because you also want to live forever, today I am here to avenge the strong son and sacrifice him with your blood." Walking towards the evil dragon, Yang Hong's murderous aura surged, and he was holding a flying knife in his hand.

"No, I'm not going to die." The evil dragon that had regained its senses screamed fiercely, and when it saw the needle and tube falling to the ground, there was a touch of madness and determination in its eyes, and it grabbed it, stabbed it in his thigh, and injected the red liquid into his body.

Seeing this scene, Yang Hong's face changed slightly, and it was too late to stop it.

"Is that a bloodthirsty potion?" Thinking of the red liquid, Yang Hong's heart moved, and he flashed to the side of the indifferent male bloody hand, pulled him to a safer place outside the operating room, and returned to the operating room.

He came here this time for the bloodthirsty potion, and from the previous conversation with the evil dragon, he could hear that it seemed that this bloodthirsty potion was newly researched, and he naturally seemed to see the effect of this bloodthirsty potion.

The evil dragon who injected the red liquid suspected of being a bloodthirsty potion into his body exuded bursts of bloody qi all over his body, and the whole person slowly stood up from the ground, his muscles bulged, and his body exuded a powerful aura, which was still rising.

"Haha, this feeling." The dragon looked at his body and shouted with laughter.

Yang Hong, who returned to the operating room, felt the change of the evil dragon, but he did not feel surprised, this kind of enhancement had been shown by Di Luo, who had been injected with bloodthirsty medicine before.

In his senses, the momentum of the evil dragon is getting stronger and stronger, and it has reached the level of a half-step grandmaster at this moment, even so, the momentum on the evil dragon's body has not diminished in the slightest, and it seems that the situation is about to break through to the grandmaster level at any time.

"Something seems wrong." Relying on the sensing realm and sensing the changes of the evil dragon, Yang Hong frowned slightly, and did not make a move to stop it.

The momentum of the evil dragon is constantly improving, proving that his strength is growing by leaps and bounds, but the aura on his body is becoming more and more unstable.

"Not good!" His face changed slightly, Yang Hong hurriedly dodged and left the operating room, grabbed the indifferent male bloody hand next to him and rushed out quickly.

Almost at the same time as he rushed out, a roar like a beast suddenly erupted in the operating room, and a violent force erupted, destroying the operating room.

"My lord, what's wrong!" The indifferent male bloody hand who was drugged, although he couldn't exert his strength, his sense as an ancient martial artist did not decline, and he noticed the violent fluctuations in the rear, and couldn't help but ask.

"The dragon injected the kind of potion they were going to test on you before, it seems that there is a problem with the potion, let's get out of here first." After explaining, Yang Hong glanced back at the back, and continued to rush forward without the slightest hesitation.

He had just burst out of the lab when a roaring roar and rumble could be heard from the other direction, similar to the situation of the dragon.

For a while, the entire ten underground floors were in chaos, and Yang Hong took the opportunity to blend into the crowd with an indifferent male bloody hand and rushed over in the direction of the elevator.

In the process, he found another violent figure, full of blood, roaring like a hideous beast, frantically attacking the surrounding researchers who were powerless, and all the researchers who were caught, the blood of the whole body gushed out from the seven orifices and skin, as if swallowed by the violent figure, and merged into the blood and qi shrouded in the violent figure, and in the blink of an eye, the researcher became a dry corpse.

Seeing this scene, even Yang Hong, who was decisive in killing, couldn't help but gasp, and the indifferent male bloody hand who also saw this scene in his eyes stared at the looming figure shrouded in blood, his face full of shock and disbelief.

"No, it can't be, how can this be." The two of them stayed away from the violent figure, and the indifferent male bloody hand still came back to his senses, muttering in exclamation, and the whole person seemed to be greatly stimulated.

"Bloody hand, what's wrong with you, is there something wrong with your body." Sensing that something was wrong with him, Yang Hong put him down and asked while checking his pulse.

"Could it be that what the poisonous dragon said is true, and I, the Blood Killer and the others are really the test samples of the organization." The indifferent male bloody hand was talking to himself as if he was a little broken.

Listening to the words of the indifferent male bloody hand, Yang Hong fell into a short silence, when he subdued the indifferent male bloody hand, he noticed the abnormality of the indifferent male bloody hand, whether it was the recovery ability or the situation detected by the pulse, it was far beyond ordinary people.

Yang Hong also heard some of the words that the evil dragon said before, and his original surprise at the abnormal body of the indifferent male bloody hand was also solved.

"Bloody hand, cheer up, whether you are a test subject or not, you are yourself, and don't forget, you are no longer a person now." While taking out a silver needle and quickly acupuncture on him, helping him remove the medicinal properties in his body that made his body weak and weak, Yang Hong opened his mouth to persuade.

The indifferent male bloody hand who lost his mind, hearing this, his body shook suddenly, and the figure of his woman appeared in his mind, and he immediately recovered from the loss of his soul.

"Thank you, sir." Nodding gratefully at Yang Hong, the indifferent male bloody hand regained his composure and continued: "The figure covered in blood just now should be my boss in the assassination department, it seems that there seems to be some problems with this second-generation blood-red potion they developed. ”

After the acupuncture was completed, Yang Hong pulled out the silver needle that was pierced on the indifferent man's bloody hand, put it in his arms again and nodded: "You are right, not only the blood killing you said, but the evil dragon who was injected with the second-generation medicine has also gone crazy." ”

Speaking of this, Yang Hong didn't have much killing intent in his eyes, because he knew that the evil dragon didn't have to do it himself, and he would soon pay a terrible price for his immortal ambition.

Although it was only a short moment just now, through the induction realm, Yang Hong completely grasped the changes in the evil dragon's body, although the injuries in the evil dragon's body recovered quickly, and his strength had also been greatly improved, but just like the bloodthirsty potion injected by Di Luo before, the transformation of his body by the second-generation blood-red elixir made him unbearable, and it was only a matter of time before he collapsed.

Originally, he just wanted to avenge the strong son and make the evil dragon pay for the previous things, but now he doesn't have to do it, the evil dragon's situation is completely his own doing, and this kind of behavior of pushing himself to a dead end is the cruelest punishment for him.

"The medicinal properties in your body have been forced out by me with acupuncture, but for the time being, your body can't fully recover, and now there is chaos in the negative ten layers, you take the opportunity to find a place to hide first and recover. physical strength, find an opportunity to take the elevator up, destroy the monitoring system, and then contact the four-eyed boy through the wireless contact headset and let him start doing it. Giving the indifferent male blood hand a pulse again, Yang Hong thought for a moment and ordered.

"Well, don't worry, my lord, leave this matter to me." Standing up from the ground, the indifferent male bloody hand nodded confidently.

After a few more words, Yang Hong immediately rushed in other directions, looking for the passage elevator to the lower floor.

At this moment, the entire negative ten layers were in chaos, Yang Hong easily caught a few researchers who were very familiar with the negative ten layers, and through some questioning and acupuncture hypnosis, what he didn't expect was that he was very lucky, and he actually caught a senior level of a negative ten layer researcher, and got a lot of important information from it.

According to the researcher's senior management, the elevator they came down from before seemed to be able to reach the minus 18 floors, but in fact, it could only go down to the minus 10 floors at most, and once the wrong press was pressed, the elevator would be immediately blocked, trapping the people in the elevator.

Yang Hong, who knew the news, was secretly glad that he didn't immediately look for the previous elevator, otherwise, even if he could open the elevator and enter it, he would be trapped in the elevator.
