Because Su Yuan had such a feeling in his heart that these big mice that appeared inexplicably in the tunnel and attacked him were by no means natural products!

Because these big mice not only have an outrageous size, but also have strong attack power and defense, but will actively attack humans. What's more terrifying is that they also have certain wisdom.

Judging from the location where these big mice appeared, they are most likely products cultivated by the Underground Biology Research Institute!

Thinking of this, Su Yuan's questions became even more...

Because Su Yuan suddenly remembered why the originally strictly sealed nuclear raw materials leaked? Is it related to this underground biology research institute?

Moreover, Su Yuan found so many skeletons in the Underground Biology Research Institute, and they died of death when they were attacked by powerful forces. So what exactly did they kill?

Is there any more ferocious animals besides these giant mice?

And what is the deep tunnel in front of you?

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

Just as Su Yuan was thinking, he suddenly heard a burst of rapid footsteps coming from the other end of the Underground Biology Research Institute.

Su Yuan was stunned and hurriedly followed the sound, and then he saw two people wearing thick anti-nuclear radiation suits appearing in front of the huge hole of the Underground Biology Research Institute, protruding towards him. It was Lan Qingling and Yu Baiying.

"Why are you here?"

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

"We heard the explosions above and were worried that something would happen to you, so we got off together!"

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

"I don't know much..."

Su Yuan shook his head and said, "But one thing is certain that those skeletons died suddenly when they encountered fierce attacks during their lifetime. Moreover, the time from being attacked to death was very short, which means that the things that attacked them had a rapid and terrifying power!"

"Well... Could it be related to the research project that this underground biology institute is engaged in?"

Yu Baiying was stunned and then guessed like this.

"It should be!"

Lan Qingling next to him interjected, and then said: "I analyzed the documents I found in the bunker office, whether it was nuclear weapons research or this biology research institute built underground in the military base, which were all confidential projects of the Japanese military during World War II, and there seemed to be a certain connection between the two!"

"Oh? What kind of connection?"

Su Yuan asked Lan Qingling in curiosity.

"The raw materials and manufacturing methods for nuclear weapons should be provided by Nazi Germany to the Japanese military, so the Japanese military secretly built this military base on this island! But for some reason, the Japanese military built an underground biology institute in the military base to study and develop biological weapons."

Speaking of this, Lan Qingling paused for a moment and said: "From the equipment and scale of this underground biology research institute, this plan should have been implemented that year! But for some reason, a serious accident occurred here, which led to the current situation..."

After hearing Lan Qingling's analysis, Su Yuan and Yu Baiying felt that things became more confusing.

"Big brother, what happened to the explosion just now?"

Lan Qingling suddenly asked Su Yuan this.

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

Su Yuan replied quickly, and then told him about the strange tunnel he had discovered and the passing of the giant mice.

After listening to Su Yuan’s narrative, Lan Qingling and Yu Baiying looked at each other for a moment.

"Big brother, take us to see the tunnel and the corpses of those giant rats!"

Lan Qingling said this to Su Yuan.

"Okay, come with me!"

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

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

Seeing the scorched corpses of more than a dozen giant rats, Lan Qingling and Yu Baiying were not scared, but came forward and observed carefully.

Lan Qingling even asked Su Yuan to use the Meiji 30-type bayonet to turn the corpses of the giant rats, allowing her to conduct more detailed observation and analysis.

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

"Genetic modification engineering?"

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

"Sister Bai Ying, although genetic engineering technology was proposed in 1973, the word gene was proposed by biologists in 1909. Several countries conducted research on this aspect, including Japan during World War II, and achieved many results!"

But Lan Qingling said this to Yu Baiying.

Yu Baiying immediately had nothing to say, because Lan Qingling was an expert in this field and a genius girl from the lhd super elite troops, and she knew more than her.

"Xiao Ling, do you think there would be other animals in the genetic engineering of the Japanese army in those days, besides these giant mice?"

Su Yuan thought about it and then asked Lan Qingling this way.

"Sure!"

Lan Qingling immediately replied this and said to Su Yuan: "There were photos of various animals in the previous documents, which showed that those animals have become basic engineering and experimental products! And you should also see that the skeletons in the Underground Biology Research Institute were not killed by these giant mice, but by creatures that were more brutal and powerful than them! Therefore, there must be other animals that have been modified with genes."

“It makes sense!”

Su Yuan nodded, expressing his agreement with Lan Qingling's statement.

"Let's go and have a look in the tunnel! Maybe we can discover more secrets!"

Lan Qingling looked at the deep tunnel and made such a suggestion.

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

Yu Baiying disagreed with Lan Qingling's proposal.

"Sister Bai Ying, you should also know that we have visited the military base above, but we can't find tools to leave this island! So, do you think there is a possibility that if we find those ships or communication equipment in that tunnel?"

But Lan Qingling asked Yu Baiying in this way.

Yu Baiying was stunned, Lan Qingling's words were not without reason.
