"Dr. Han, this special creature is too valuable, I'm afraid you won't give it to me easily." Chen Ye retracted his gaze, locked his gaze on Dr. Han, who was smiling kindly, and then asked softly.

Dr. Han smiled and said, "Of course I won't give it to you easily, I need you to do something for me that is not simple." ”

"Something."

"Since you can bring back that baby zombie vaccine from the City of Terror, you must know about the super existence of the City of Terror, the Primordial Mother." After seeing Chen Ye nodding, Dr. Han continued: "At the beginning, my armed escort team was buried under the hands of the primordial mother body, and the primordial parasite in your hands was exchanged for the lives of the entire armed escort team members. ”

"I see what you mean." After Chen Ye said this, the system's prompt sounded closely.

Bite.

System Prompt: You have accepted [Vengeful Primordial Mother].

Mission Name: Vengeance of the Original Mother.

Mission Description: The indelible history that disappeared in the dust still echoes in Dr. Han's mind, and the bloody destruction scene of the entire armed escort appears like a nightmare on every night when he closes his eyes, mission requirements: Kill the primordial matrix, eliminate the nightmare in Dr. Han's heart, reward: special equipment +1, difficulty: advanced, note: After obtaining the primordial parasite, the quest is activated.

...

"Do you know why I chose you for this task?" Dr. Han asked, still with a kind face and a bit of kindness in his tone.

Chen Ye shook his head, expressing his puzzlement.

"Remember what I said to you when we first met?" Dr. Han looked at Chen Ye meaningfully and said.

After Dr. Han's reminder, Chen Ye suddenly remembered that when he captured the biochemical base a few days ago, he met Dr. Han and the others who had become a young body in the sewers, and the former had said to him that he had five-star growth potential.

"Five-star growth potential." Chen Ye recalled for a moment and said.

Dr. Han nodded with a little relief, and said, "Yes, I didn't expect you to remember, it's really a bit rare, and the reason why I chose you as the carrier of the primordial parasite is because you are the only one who has the potential to control it among the people I have seen, and if the rest of the people want to carry this primordial parasite, they will die at least and become its slaves at worst." ”

"Death at the lightest, slave at the worst, this is too exaggerated." Chen Ye suddenly smacked his tongue in his heart, and his eyes staring at the box in his hand again had changed from hot to cautious, this was definitely a double-edged sword full of temptation.

"Shu disciple Xiaoyou, with the old man on your side to assist you in the injection, plus your five-star level growth physique, the probability of your success in devouring the primordial parasite is at least 75%." Dr. Han said as he took out the various medical assistance boxes from the Space Acceptance Ring, "We can start now, come with me." ”

"Wait." Chen Ye hurriedly stopped.

"Is there anything else you have to do?" Dr. Han was puzzled.

"I think it's necessary for me to write some suicide note or something." Chen Ye said with a gloomy face, extremely solemn.

Dr. Han was immediately speechless...

Five minutes later, Chen Ye was lying on the operating table specially prepared for him by Dr. Han wearing only a pair of pants, his limbs, neck, waist, and thighs were locked by alloy buttons.

"No, even the head." Watching Dr. Han take an iron helmet similar to a rugby ball from under the operating table, Chen Ye's eyebrows couldn't help jumping.

Ignoring Chen Ye's panic, Dr. Han directly put the rugby helmet on Chen Ye's head, and then connected the lock at the lower end of the helmet to the operating table, after all this was done, Dr. Han began to take out a needle containing dark green crystal liquid from the auxiliary medical box, and said while injecting: "This is a body anesthetic, which can reduce the pain transmitted from all parts of the body by 60%. ”

"This is a leukocyte stimulant that increases cellular phagocytosis by 200% for a duration of ten minutes." After one injection was completed, Dr. Han took out another injection.

"This is an inert injection of primitive parasites, which can be injected into the body in advance, which can increase the cellular inertness of primitive parasites, thereby reducing their chance of regurgitation against white blood cells."

Although Chen Yetou was in an olive helmet, every word of Dr. Han came into his ears one by one, and the name of each injection in the latter's words was like one missile after another bombarding his heart.

Body anesthesia injection, A-level survivor base price 7500 gold coins, leukocyte stimulant, phagocytosis increased by 200% This one, the base is not for sale for the time being, the lowest model is 110%, and the price is 10000 gold coins.

This list was inadvertently seen by Chen Ye in the Iron and Blood Battle Soul Combat Headquarters, he was a little puzzled at the time, and finally learned from Zhao Yan's mouth that these injections are for those trade union members who are ready to advance to the juvenile, according to the type of injection on the list, the identity value of a juvenile profession is about 20,000 game coins, even if it is converted into real coins, it takes 18,000, so it can be seen that if you want to be promoted to an alternative profession, it is difficult to succeed without strong funds as a guarantee, even if you succeed by luck, It is also necessary to endure extremely tragic suffering.

It's just that what Chen Ye didn't expect was that in order to obtain the ultimate nirvana skill of a special creature, the gold he needed to spend was far more than 3 to 4 times higher than that of advancing to the juvenile profession.

"It's about to start, Shu disciple Xiaoyou, are you ready?" After Dr. Han took out the original parasitic vaccine from the special equipment storage box, he came to Chen Ye's left arm and asked in a low voice.

"Okay." Chen Ye replied extremely quickly, however, if he could see the dark blue injection in Dr. Han's hand at this time, I am afraid he would not have answered so decisively, because, not so much that the latter was holding a needle in his hand, it was more like a container tube containing countless dark blue thin strip-shaped tentacles, and what was to be injected into his body was not a virus injection like a juvenile, but the countless dark blue strip-shaped tentacles in the container tube.

Flutter.

The subtle vibration when the tip of the needle pierced the flesh, as well as the smell of blood and body temperature from the mouth of the needle, seemed to be like a powerful active potion, and immediately activated the dark blue striped tentacles in the container barrel, and then these small striped tentacles like hairs entered Chen Ye's blood vessels and muscle tissue along the needle mouth...

...... Scene switching.

Zhao Yan and the others, who were waiting outside the door of Dr. Han's laboratory, looked at each other with blank expressions.

"You say, why did Dr. Han leave Ye Zi alone in the laboratory?" Zhao Yan, who had been waiting for a long time, was the first to break the calm and asked.

"Can two men do it together?" Soul Death had a relieved expression: "What's more, it's an old and a young."

"I don't know." Harbor had a helpless face, and his disdainful eyes stared at the scheming fat man in front of him.

After about seven or eight minutes, there was a sudden scream of extreme pain in Dr. Han's laboratory, Zhao Yan's face immediately sank after hearing the sound, and he naturally knew the source of this scream...
