A week later.

In the restaurant at the maritime airport.

Su Yu and Tanya sat by the window, eating lunch.

There were quite a few people sitting in the hall, most of them students.

They looked at Tanya and Su Yu with a little awe in their eyes.

Tanya is able to fly freely in the air, has the ability of a magister, and many people have seen the artillery spell that covers the ground, which is a realm that humans cannot reach.

And Su Yu is even more mysterious.

On the surface, he is an ordinary high school student, but in fact, one person blocks thousands of zombies, and the power of the detonation charm in one hand is amazing.

Just looking at ability, Tanya is far superior to Su Yu, but between the two, Su Yu is the team leader, which shows that he is stronger.

"Mr. Su Yu, the professor, please go." A soldier approached and saluted.

"I see." Su Yu frowned and disappeared.

Everyone in the hall was amazed when they saw this scene.

Tanya drank her coffee and looked out the window.

"The potential is good, but unfortunately he is not a known figure, and the risk of recommending him seems to be a bit high." Tanya muttered.

……

In an underground laboratory.

"Su Yujun, I'm sorry to disturb your lunchtime. It took us a week and with the help of a few immunizers to finally finish the first dose, and now it's time to test it. An old professor apologized.

"Have you started?" Su Yu looked at the soldiers who were locked in the glass room.

"We knew that the virus had a short onset, but in order to ensure that there was an accident, we had already kept him there for an hour. There are no special cases yet..."

"Open the door, I have the easiest way to test it." Su Yu interrupted the old professor's words.

"Yes." The old professor hurriedly asked people to open the door.

Su Yu walked into the glass room, and the soldiers who were being tested saw him and hurriedly saluted.

"Arms outstretched." Su Yu looked at the wound on his arm.

The soldier did not hesitate and put his arm in front of him.

Su Yu put one hand on his arm, and the light of medical ninjutsu emanated, and in a short time, the wound was completely healed.

"Su Yujun, is this okay?" The old professor stood behind Su Yu and asked.

"My medical ninjutsu can quickly repair wounds, and at the same time, it will also accelerate the erosion rate of the virus, which will mutate in half an hour, but after I use medical ninjutsu, it will take up to ten minutes. If the potion is successful, he will not exhibit any abnormal effects for ten minutes. Su Yu explained.

This is something he discovered recently.

When the old professor heard this, he stared at the soldier.

Everyone in the lab was watching, and not a single one made a sound, and this was the time to decide what they were trying to do.

Ten minutes was too long for them, and as the last second passed, cheers rang out from the lab.

"Congratulations, the potion is ready to be manufactured on a large scale." Su Yu said a word to the old professor and walked out of the laboratory.

In less than an hour, the news of the success of the immunization agent spread throughout the sea airfield.

Its success means that the remaining human beings have the strength to fight and are no longer afraid of zombies.

What's more, their offspring will also be immune to the virus.

Pilots of airplanes at sea airports are still alive, and as long as the medicine is produced on a large scale, it can be sent to all parts of the world.

……

Night, on the island.

This has become the exclusive area of Su Yu and the others, and even if the sea airport is very lively, they have no intention of living there.

Except, of course, Minami Satoka, who, as the commander of the battle squad, naturally couldn't live here.

On the deck of the yacht.

Su Yu looked at the bright moon in the sky.

There are more than 1,000 survivors at the sea airfield, and now with immunity agents, even without him and Tanya, humans will be able to successfully fight back.

In half a month, the number of Su Yu's copper treasure chests has reached the upper limit of acquisition, but there is still a half-month countdown.

"System, can't you let me go back early?" Su Yu asked a system in his heart.

"The countdown is over, and it's back automatically." The system's answer remains the same.

"Su Yujun..."A voice sounded.

"......" Su Yu turned his head to look at Yuriko Takashiro in a swimsuit.

Ever since he rescued Yuriko Takashiro, Saya Takashiro has been looking at him with strange eyes.

Especially every night, when Yuriko Takashiro walks into Su Yu's room, it makes Saya Takashiro think a lot.

Actually, it was just that Yuriko Takashiro saw that Su Yu was too tired, so she gave him a knee pillow.

Other than that, the most he could do was to blind him.

"Can I sit here?" Yuriko Takashiro said softly, and as she spoke, she had already sat down.

"I didn't go to clean up the zombies today, so I don't need a knee pillow..."

"Don't force it, Su Yujun, I know you're working hard." Yuriko Takashiro hugged Su Yu.

"......" Su Yu, how should he explain this misunderstanding?

"You say you're a mercenary, but you're actually a hero. I've always been thinking about humanity, cleaning up the zombies in the city every day, saving those who are trapped, resisting thousands of zombies and saving hundreds of survivors with my own strength..."Yuriko Takashiro's voice was very gentle.

Su Yu wanted to say that he was for the dungeon and the virtual treasure chest.

"Thank you for protecting us, you are the hero in my heart, Su Yujun..."Yuriko Takashiro lowered her head.

Su Yu was stunned for a moment, and then he smelled a strange fragrance.

"What is this?" Su Yu hurriedly pushed away Yuriko Takajo.

"You'll find out in a moment." Yuriko Takajo said with a slight blush.

Su Yu opened his mouth, feeling the acceleration of his heartbeat, and he understood.

……

The early morning sun set on the deck, and Su Yu woke up.

My head was groggy, as if I had drunk too much wine.

"Newcomer, you're so lucky." Tanya's teasing voice sounded, and she threw Su Yu a piece of clothing.

Only then did he notice that the clothes on his body were missing.

"Last night, who else but Yuriko Takashiro?" Su Yu saw the marks on the deck, and the corners of his mouth twitched.

"Well, you guess." Tanya smiled wickedly.

Su Yu lowered his head and thought about it, and suddenly remembered something.

"I remember you said a few days ago that my bloodline is extremely rare, and my descendants will definitely become strong like me?" Su Yu looked up at Tanya.

"It's true, and I didn't expect them to be that crazy." Tanya shrugged.

"That's... Su Yujun, it's time for breakfast. Saya Takashihiro's voice sounded from behind.

Su Yu turned his head to look at Saya Takashihiro.

"There's... What's the matter? Saya Takajo blushed and avoided Su Yu's gaze.

"It's fine." Su Yu got dressed and got up.

Tanya smiled and followed behind the two.

When the three of them came to the living room, the atmosphere was even more subtle.

Poison Island Tsuneko and Miyamoto Rei saw Su Yu, and their pretty faces turned red.

"What about Mrs. Takashiro?" Su Yu asked.

"Mother has gone to the sea airport," Saya Takashiro whispered.

Su Yu glanced at Minami Sayaka and Jukawa Shizuka's room again, this pair was normal, and they never ate breakfast.
