Because Su Yuan had a feeling in his heart that these big rats that appeared inexplicably in the tunnel and attacked him were definitely not a product of nature!

Because these giant rats not only have ridiculously large sizes, but also powerful attack and defense capabilities, and will actively attack humans. What's even more frightening is that they also possess a certain amount of intelligence.

Judging from the places where these big rats appear, they are most likely products cultivated by underground biological research institutes!

Thinking of this, Su Yuan had more questions in his heart...

Because Su Yuan suddenly remembered, why did the nuclear materials that were strictly sealed leak out? Could it be related to the underground biological research institute?

Moreover, Su Yuan found so many skeletons in the underground biological research institute, and they all died after being attacked by powerful forces. So what exactly were they killed by?

Are there other more ferocious animals besides these giant rats?

And what is this deep tunnel in front of us used for?

These questions made Su Yuan even more curious. He felt that there were many amazing secrets hidden in the abandoned military base on this unknown island.

Just as Su Yuan was thinking, he suddenly heard a rush of footsteps coming from the other side of the Underground Biological Research Institute.

Su Yuan was startled and hurriedly followed the message. Then he saw two people wearing thick nuclear radiation protection suits appearing in front of the huge hole in the underground biological research institute. They poked their heads towards him. It was Lan Qingling.

and Yu Baiying.

"Why are you here?"

Su Yuan hurriedly walked over and asked the two women this way.

"We heard an explosion from above and were worried that something might happen to you, so we came down together!"

Yu Baiying responded like this, and then asked Su Yuan: "We saw a lot of skeletons in the basement, what is going on?"

"I'm not so sure either…"

Su Yuan shook his head, and then said: "But one thing is certain. Those skeletons were suddenly attacked by fierce attacks before they died. Moreover, the time from when they were attacked to when they died was extremely short, which means that what attacked them was...

It has swift and terrifying power!”

"Hmm...could it be related to the research project of this underground biological research institute?"

Yu Baiying was stunned for a moment, and then guessed like this.

"should be!"

Lan Qingling next to him interjected, and then said: "I analyzed the documents found in the bunker office. Whether it was nuclear weapons research or the biological research institute built underground in the military base, they were all related to the Japanese army during World War II.

It’s a confidential project of the other side, and there seems to be a certain connection between the two!”

"Oh? What kind of connection?"

Su Yuan asked Lan Qingling curiously.

"The raw materials and manufacturing methods of nuclear weapons should have been provided by Nazi Germany to the Japanese military, so the Japanese military secretly built this military base on this island! But for some unknown reason, the Japanese military

Within the base, an underground biological research institute was built to research and develop biological weapons."

Having said this, Lan Qingling paused for a moment and then said: "Judging from the equipment and scale of this underground biological research institute, this plan should have been implemented back then! But for some unknown reason, a serious accident occurred here.

As a result, it became like this..."

After hearing Lan Qingling's analysis, both Su Yuan and Yu Baiying felt that the matter had become more complicated and confusing.

"Brother, what happened with the explosion just now?"

Lan Qingling suddenly asked Su Yuandao.

"Oh, I found some exaggeratedly large rats in the tunnel inside!"

Su Yuan hurriedly replied, and then told him about the strange tunnel he discovered and the story of those giant rats.

After listening to Su Yuan's narration, Lan Qingling and Yu Baiying looked at each other.

"Brother, take us to see that tunnel and the corpses of those giant rats!"

Lan Qingling said this to Su Yuan.

"Okay, come with me!"

Su Yuan nodded, then led Lan Qingling and Yu Baiying towards the tunnel.

After a while, the three of them arrived at the entrance of the tunnel.

Seeing the charred corpses of more than a dozen giant rats, Lan Qingling and Yu Baiying did not feel scared, but moved forward and observed them carefully.

Lan Qingling even asked Su Yuan to use the Meiji 30-style bayonet to turn over the corpses of those giant rats so that she could conduct more detailed observation and analysis.

After struggling for a while, Lan Qingling said: "These giant mice are not born in nature, but are the product of genetic modification projects."

"Genetic modification project?"

When Yu Baiying heard this, she hurriedly said: "As far as I know, genetic engineering technology originated in 1973, and genetic modification only appeared in the past twenty years. How could Japan have such advanced technology during World War II?"

"Sister Bai Ying, although genetic engineering technology was proposed in 1973, the word gene was proposed by biologists in 1909. Then several countries conducted research in this area, including Japan during World War II.

, and achieved a lot of results!”

Lan Qingling said this to Yu Baiying.

Yu Baiying suddenly had nothing to say, because Lan Qingling was an expert in this field and a genius girl from the LHD super elite unit. She definitely knew more than she did.

"Xiao Ling, do you think that in addition to these giant rats, there will be other animals in the genetic engineering of the Japanese army?"

Su Yuan thought for a while and then asked Lan Qingling.

"there must be!"

Lan Qingling immediately replied like this, and then said to Su Yuan: "There were photos of various animals in those documents before, which shows that those animals have become experimental subjects for genetic engineering projects! And you should be able to tell it, big brother.

, those skeletons in the Underground Biological Research Institute were not killed by these giant rats, but by creatures that were more ferocious and powerful than them! Therefore, there must be other genetically modified animals."

"That makes sense!"

Su Yuan nodded, agreeing with Lan Qingling's statement.

"Let's go take a look in the tunnel! Maybe we can find more secrets!"

Lan Qingling looked at the deep tunnel and made this suggestion.

"I think it's better not to go in! What we should consider now is how to leave the island. If we venture into this tunnel, wouldn't it be very troublesome if we encounter danger?"

Yu Baiying did not agree with Lan Qingling's proposal.

"Sister Bai Ying, you should also know that we have searched all over the military base above, but we can't find the tools to leave the island! So, do you think there is a possibility that if we are in that tunnel,

Find those ships and other things, or communication equipment?"

Lan Qingling asked Yu Baiying this way.
