Studying biochemistry in anime is definitely a mistake

"Mom, I heard from Dad that you two got married because of pregnancy, right?"

Izumi Shimomura, who was still in elementary school, suddenly asked his mother very happily.

"Yeah, why are you laughing like that..."

The woman, who was still called Shimomura Sawako at the time, asked back to her son.

"Because this means that Mom and Dad will marry because of me, right? I'm so happy!"

Izumi Shimomura explained to his mother with a smile.

……

——How long has it been since I last saw Izumi smile?

Tian Zezi suddenly thought of this at the moment when she stabbed the kitchen knife into Tian Zhongcong's back.

"Bastard!"

Tian Zhongcong felt pain and the phone in his hand fell to the ground, but he reacted immediately, turned around, snatched the kitchen knife from Tian Ai Zeko's hand, and stabbed it into the other person's chest.

After doing all this, Tianzhong Satoshi collapsed to the ground and died because his heart was pierced by a kitchen knife.

Before she died, Tian Zezi confessed to the direction where Shimomura Izumi ran away:

"I'm sorry... Quan..."

……

"Too late……"

After listening to the recording, Izumi Shimomura, who was lying on the hospital bed, couldn't help but shed a tear from the corner of his eye.

Afterwards, the curve on the electrocardiogram that had been connected to Izumi Shimomura completely flattened.

"So he's not a demi-human?"

After confirming the death of Izumi Shimomura, Tosaki Yu immediately stood up from his chair:

"It seems that I will have to continue doing this dangerous work alone in the future."

But just when Tosaki Yu was about to leave the ward, Izumi Shimomura, who was supposed to be dead, suddenly got up from the hospital bed.

The next day, at the grave of Izumi Shimomura's biological father and mother.

Tosaki Yu said to Shimomura Izumi:

"This is the contract I signed with you personally. The Ministry of Health, Labor and Welfare is not aware of it. Your mission is to protect me from the threat of subhuman alien abilities. The record of you being a subhuman is kept by me in an unknown place, but if I die, someone will always find it.

The name Izumi Shimomura has been marked as dead in the government's archives. Totsuka Ayaka, this will be your name for the rest of your life."

"I see……"

Izumi Shimomura, no, now it should be Totsuka Ayaka, he said to his parents' graves at the end:

"Mom...this time...until the very end...I won't run away! I will try my best to do it again!"

Back to the present, in the Nanten Building, Tanaka Koji shook his head, trying to free himself from Totsuka Ayaka's memory.

After seeing the split-mouthed black ghost he released and the triangular-headed black ghost released by Totsuka Ayaka gradually disintegrate due to the annihilation of the black particles that made up their heads.

Koji Tanaka hit Ayaka Totsuka on the back of her head, as she was in confusion due to the memory of being subjected to human experimentation. Then, before Kei Nagai could react, he immediately turned around and ran downstairs.

After Kei Nagai reacted, he immediately shot Ayaka Totsuka in the head. Just as he was about to get up and chase Koji Tanaka, his cell phone suddenly rang - it was a call from Nan Tianren.

Kei Nagai had no choice but to let Koji Tanaka go first and answer the call from Ren Nan Tian. Then the isolation wall of the Nan Tian Building was lowered, and everyone in the building was trapped in this huge cage.

"Nantianren...is he dead?"

Hearing the gunshot from the other end of the phone, Kei Nagai said in disbelief.

"What? You said Nan Tianren is dead?"

After hearing what Nagai Kei said, the resurrected Totsuka Ayaka asked him in disbelief.

"I don't know...we have to go to the lab right away!"

After Kei Nagai finished speaking, he and Ayaka Totsuka rushed to the laboratory on the fifth floor.

At the same time, at the stairs between the second and third floors of the Nantian Building, the corpses that had been injected with unknown liquid by Nantian Ren suddenly crawled up from the ground one after another.

At some point, the hearts of these corpses suddenly began beating violently again, and the accelerated blood supply caused the entire head to turn the same blood red as Nan Tianren's head.

"Oh my god, what the hell is this?"

Koji Tanaka, who was running downstairs, was the first to encounter these monsters with blood-red heads.

Two crimson heads immediately pounced towards Tanaka Koji.

Upon seeing this, Koji Tanaka immediately fired back, and the two bullets pierced through the heads of the two crimson heads.

But it was completely useless. A mere pistol bullet was not enough to kill the Crimson Head. When Nan Tianren was conducting an experiment on Kei Nagai, he emptied an entire magazine before he successfully killed the Crimson Head that Kei Nagai had transformed into.

The next second, Koji Tanaka was about to release his split-mouthed black ghost again, but before the split-mouthed black ghost could fight with the two crimson heads, a security guard corpse next to Koji Tanaka suddenly reached out and grabbed his ankle, then bit his leg and tore off a large piece of muscle.

"what!"

A piercing pain instantly pierced into Koji Tanaka's bone marrow. He quickly emptied the magazine, shot the crimson head that was biting him, then reloaded the bullet and turned the gun around to commit suicide and refresh his status.

However, when Koji Tanaka opened his eyes again, the security personnel who had been killed here by him and the Takahashi brothers, crawled up from the ground, their heads turned blood red, and surrounded his body.

In the eyes of Koji Tanaka, the security personnel he had killed now seemed to have turned into evil spirits, wailing, crying, and roaring, wanting to pay for their lives.

"Don't come over here!"

Koji Tanaka lay on the ground, shooting randomly at the crimson heads that were gathering around him, but the bullets seemed to have no effect at all on them.

Even though the split-mouthed black ghost could hold back three or four crimson heads, he still couldn't withstand more than a dozen crimson heads rushing towards him at the same time.

In the end, Koji Tanaka's figure was submerged by the crimson heads, and the monsters frantically devoured Koji Tanaka's body until his head also turned blood red and became one of them.

As for the two crimson heads that ate the most flesh and blood, their skin gradually fell off, more muscles grew, and their bones quietly changed, and they began to walk on all fours.

The most important thing is that after their brains expand, they break through the limitations of the skull and cover half of the head. Their vision and sense of smell are completely lost, and only their hearing becomes abnormally developed.

After consuming large amounts of flesh and blood, these crimson heads began to mutate and evolved into lickers.

Nan Tianren's experiment did not fail, but what he didn't know was that the Crimson Head would gradually transform into a licker only after absorbing the DNA of other life forms.

After all, this information was not mentioned in the information provided by the system, because in the original "Resident Evil", the Umbrella Corporation did not know where the Lickers came from. The Lickers were not BOW developed by the Umbrella Corporation at all. They were just mutant individuals that were accidentally born after the T virus leaked.

On the other side, Kei Nagai and Ayaka Totsuka finally arrived at the laboratory where Nan Tianren died.

Looking inside through the hole in the dividing wall, one can still see Nan Tianren's mind-blowing corpse.

"Nan Tianren...was really killed..."

Totsuka Ayaka still couldn't believe that Nan Tianren would die so easily:

"How on earth did Sato manage to make a hole in the 30-centimeter-thick isolation wall?"

"No... The plan to isolate Sato inside the building has failed."

Kei Nagai looked at the fist-sized hole in the isolation wall and said in despair as if his soul had been sucked out.

"What do you mean? Didn't Nan Tianren tell us to continue fighting Sato in this closed cage until we successfully capture him? Isn't that why Nan Tianren completely sealed off the building?"

Totsuka Ayaka looked at Nagai Kei in confusion.

"This cage can no longer hold him. Sato has already made a hole in such a solid wall. This means he has figured out how to leave this building. He may have sensed some special properties of the demihumans!"

"What kind?"

"Go to the rooftop! We need to prepare to escape. Even if we want to continue fighting him, we must regroup!"

After saying this, Kei Nagai took Ayaka Totsuka and ran towards the rooftop.

At the same time, Sato was searching for Kei Nagai in the building.

As he was walking, he suddenly heard footsteps behind him. He immediately raised his gun and saw a figure in security uniform walking towards him.

Just as Sato was about to pull the trigger, he was surprised to realize that the figure in security uniform was actually Koji Tanaka in a different outfit.

"What? It's you, Tanaka. I thought you were the security guard in the building."

After seeing the identity of the person, Sato immediately put away his gun and continued to ask Tanaka Koji:

"Brother Tanaka, why didn't you run away with Takahashi and A Yuan? By the way, why is your face so red? Did someone's blood splash on it?"

Tanaka Koji did not answer Sato's question, but roared and rushed towards the other party.

It was not until then that Sato noticed that the red blood on Tanaka Koji's head did not seem to be the blood splashed on his face by other people.

Without any hesitation, Sato immediately took out his pistol again, aimed at Tanaka Koji's blood-red head and pulled the trigger until the magazine was empty. Only then did he successfully shoot and kill the opponent before Tanaka Koji was about to bite him.

As Koji Tanaka died and then resurrected, the blood-red color on his head completely faded away.

"What happened? What got your head like that?"

After reloading, Sato still pointed the pistol at Tanaka Koji's head and asked.

"Sato-san... Monster... There's a monster in this building!"

Tanaka Koji, who had transformed back into a human, spoke to Sato breathlessly.

"monster?"

Sato asked back, somewhat confused.

"Yes! That's right! There are monsters in this building! The security guards killed by me, Takahashi and A Yuan have all turned into monsters with blood-red heads!"

After regaining his composure, Koji Tanaka helped Sato stand up.

"You mean, that monster with a red head is just like you just now?"

At some point, Sato suddenly recalled the red skull that was revealed after Nan Tianren tore off his skin. After Nan Tianren turned into that state, his strength and speed increased significantly.

"Are you saying that I just turned into that kind of monster?"

Before Tanaka Koji could finish his words, more crimson heads appeared from the corridor he came from, and attacked the two of them with bared fangs and claws.

"Get to the rooftop! We have to escape now!"

He already knew that he had to empty an entire magazine to kill a Crimson Head, and that this monster was contagious and could turn himself into an irrational monster. Facing a dozen aggressive Crimson Heads, Sato, who only had a pistol and a tranquilizer gun in his hand and could no longer release the Black Ghost today, immediately decided to escape.

But just a few steps after Sato and Koji Tanaka ran in the opposite direction, two lickers suddenly attacked them from the ceiling in the opposite direction.

The two lickers pounced on Sato and Koji Tanaka respectively.
