I can upgrade in the last days

Chapter 520 Breathing underwater, enlarged version of the devil!

Indus Base, Department of Genes.

In the entire factory building, the assembly of serums is proceeding in an orderly manner. At this time, the mass production is already very orderly, and the shipments are increasing every day.

"Commander Song, why are you here?"

Seeing Song Yan, Xu Pin quickly greeted him. He has now changed from a laboratory assistant to a factory supervisor.

"I want to talk to Professor Pei about something, is he still in the office now?"

Song Yan took a look at the factory in front of him, and it could be said that the construction was on the right track.

"Yes, I won't accompany you there for now. There are still some things that I need to take care of here."

Xu Pin pointed in the direction of the office with a smile on his face, and then continued to take charge of what he should be responsible for.

Song Yan turned away and gently pushed open the office door. The situation inside was very clear, with documents piled up on the desk.

The old man who was over fifty years old seemed to be radiant at this time. He looked at the documents very carefully and even took off his reading glasses.

"Who?"

"It's me, Professor Pei. I want to consult you about something."

Song Yan chuckled, then pulled up a chair and sat down, with a desire for knowledge in his eyes.

"Oh, Commander Song, you should do it first. If you have any questions, just tell me."

"I would like to ask, if we are going to conduct underwater combat, can our current survivor genes be able to complete underwater combat?"

Song Yan's question was very general, and there was no specific question.

Pei Hongcai frowned first, then shook his head and said:
"I can't say well about this matter. After all, I can't directly explain what happened today."

"Then let's change the way. If underwater creatures wash ashore, then we can fight back. So if we go underwater, can we fight?"

Song Zhensheng reorganized his words and asked his question again.

Pei Hongcai nodded at this time, he expressed his understanding, and then said:

"I understand what you mean. You mean, can our fighters breathe underwater like fish?"

"Yes, after all, there may be an underwater contest with them in the future."

Song Yan frowned. Although he had not expected this, he had to prepare for it now.

"Underwater? Is it marine life?"

Pei Hongcai raised his head and met Song Yan's eyes.

The latter shook his head and said:

"It's a creature that is more terrifying than marine life. It's hard to explain this kind of thing. Can you make something that breathes underwater?"

If the problem of underwater breathing can be solved, then it should be regarded as the first step to target the devil.

"This kind of thing should be possible in theory, but it will take some time."

Pei Hongcai shook his head. If he wants to make this gene-altering medicine in the short term, the time required may be calculated to a certain extent.

"Okay, I see. Let's try to get started on this matter. We don't have enough time, but we should have it."

Song Yan nodded, then stood up and walked outside.

Through his conversation with the former, he discovered that this matter was indeed becoming more and more urgent, and he must improve his strength as soon as possible.

In the upper space, an old man was sitting peacefully by the lake fishing, his eyes were very calm.

Suddenly, the lake surface rippled on his fishing rod. He waved his hand gently, and a golden light was caught by him.

"It's so fast. Let me see what happened."

After he finished speaking, the golden light flew into the air, and after shaking off the moisture on his body, it turned into a streamer and entered his mind.

A series of scenes continued to emerge, just like a movie.

After a long time, the old man slowly opened his eyes, showing a strange look and said:
"It's really strange that such a thing would happen unexpectedly."

He shook his head, then put away his fishing rod, stood up, and walked towards his courtyard gate.

The scene around him was constantly changing as he moved.

Just ten steps away, the front of the old man turned into the far door of his home, and the color of the sky in the distance also changed to the trace left by the setting sun.

"Grandpa, what are you eating today?"

The child came out bouncing around the corner not far away, with a hint of expectation in his eyes.

"Today, eat steamed sea bass today."

The old man walked into the courtyard door with a smile, and the child followed him.

After a sumptuous dinner, the old man sat alone in the courtyard. He slightly raised his eyes and glanced at the sky. At this time, the sunset had completely gone, leaving only the starry sky and a bright moon.

"Could it be propelled? But what is it that accelerates the speed?"

The old man raised his hand again, and a ray of light flew towards the sky along his fingers, and disappeared into the dark night.

Wutong base, the entrance of the ruins.

Song Yan walked in without hesitation, and the familiar Oluto picture appeared around him, and then transformed into a gray and white three-dimensional space.

"I hope the reward this time will not disappoint me."

After taking a deep breath, he walked inside.

The familiar scene flashed again, this time the appearance of the battlefield was a little different from before, but a broken canyon.

Song Yan stood on the edge of one side and looked towards the canyon, but found that the bottom was bottomless.

"Strange, why did the map suddenly change?"

He didn't quite understand, it was completely different from what he imagined.

Boom!
A bell rang, and he suddenly looked up, only to find that opposite him, black figures began to gather one after another, they were the devils!

"Devil? But, such a long distance, do you want me to fly over?"

Song Yan was a little puzzled, but when he was about to fly over, he found that the group of demons were rushing towards him.

However, there is a crack like an 800-meter runway in the middle?
The dense black | The demon started to sprint, and then fell into the crack. Song Yan stood there in a daze, a little dazed.

They didn't need to take action at all, so they just died generously?
But soon, he discovered the strangeness of this matter. After the hundred demons jumped down, there was a sound for ten seconds.

Pfft!

It feels like a cracked egg.

Soon, a figure that looked seven or eight times bigger than ordinary demons jumped out of the crack.

Such a monster is not the figure that Song Yan had seen before. The height of an ordinary demon is only 20 meters. This black shadow is [-] meters tall, nearly eight stories high!

"Roar!"

After it rushed out of the crack, it roared and rushed towards Song Yan.

"What exactly is this?"

Song Yan was a little dazed, and then the Demon Blade emerged from his hand, rushing towards the huge and ferocious black shadow.

From the details of the sunlight reflection, it can be clearly seen that each scale is very clear and looks tough and powerful.

Song Yan's speed was very fast. He first dodged the black shadow's attack, and then went around its back, planning to find its weak point first.

"How come, here?"

He was a little confused, this enlarged version of the demon also had its own energy core, but this core was wrapped in layers of black scales.

Such a position is located at the highest position of the entire spine.

In the hand of the enlarged version of the devil, there is still a huge bone knife, which he swings with great force.

Song Yan had no choice but to dodge the attack, and then pierced it towards the core. The demon-loving blade in his hand also became very shiny at this moment, and looked extremely sharp.
