"Could it be that this is a secret base for Japanese biologists to cultivate biological weapons?"

Su Yuan suddenly recalled the contents of Yamashita Fengwen's secret order.

Su Yuan was shocked when he thought of this!

What if the Japanese biologists really developed a terrible biological weapon here? Maybe, even the ending of World War II will not be what it was in history.

But such a situation did not happen. Su Yuan secretly breathed a sigh of relief and continued to check the situation in the room.

Later, Su Yuan discovered that almost all of the huge glass bottles in the room were broken, and even traces of some liquid remained on the floor.

Su Yuan leaned over and took a look. Judging from the traces of liquid, it was probably some kind of biological culture fluid.

So Su Yuan quickly thought that these huge pillar-shaped glass bottles once cultivated some kind of special creatures!

Later, I don’t know what happened, causing the glass bottle to break, and the special creature inside also escaped...

In order to confirm his guess, Su Yuan continued to search inside the house.

Soon, Su Yuan discovered a huge hole in the innermost corner of the house!

Su Yuan judged from the location of this huge hole that it should be the ventilation opening of this basement room.

In other words, those special creatures should have escaped from this huge hole.

But where did those special creatures go?

With this question in mind, Su Yuan simply opened his "Sky Eye" and swept towards the huge hole.

Soon, Su Yuan discovered that outside the huge cave, there were actually several huge exhaust pipes.

These exhaust pipes are large enough for an adult to get into.

Su Yuan guessed that those special creatures probably escaped through the exhaust pipe!

As for where they escaped, Su Yuan didn't know...

At this time, Su Yuan suddenly heard a sound of "instigating" coming from the direction of the exhaust pipe.

The sudden appearance of such strange sounds in the originally quiet basement can't help but give people a creepy feeling.

Su Yuan was not afraid, but curious, so he looked in the direction where the sound came from.

I vaguely saw a dark shadow flashing past the corner of the exhaust pipe.

Su Yuan became more and more curious. Whether it was a military base or this basement, which had been abandoned for many years, there were still living things appearing? Is there any secret hidden there?

Thinking of this, Su Yuan moved, jumped over the huge hole, then followed the exhaust pipe and hurried forward.

Soon, Su Yuan came to the corner of the exhaust pipe, and then saw a track paved with rails!

In front of this track is a dark and deep arched tunnel, and I don't know where it leads.

Su Yuan was greatly surprised. He did not expect to see such a scene. It seemed that there were many secrets hidden in this basement!

At this moment, a black figure suddenly and quickly jumped out of the arched tunnel.

Su Yuan took a closer look and saw that it was a huge rat!

This rat is astonishingly large, comparable to a calf, with black fur all over its body, and its eyes are shining with faint red light. The most special thing is that the mouth of this big rat is as white as a scimitar.

The sharp teeth look particularly scary.

To be honest, this was the first time Su Yuan saw such a huge rat, which was almost as big as an adult!

After the big rat sprang out of the tunnel, it stared straight at Su Yuan with its two red eyes, then bared its teeth at him, as if it wanted to attack.

Su Yuan couldn't help but be startled. It looked like this big rat was very aggressive!

Sure enough, the big rat stared at Su Yuan for about half a minute, then suddenly jumped forward and rushed towards him. It was extremely fast and agile, comparable to a ferocious beast!

Su Yuan dodged and avoided the attack of the big rat.

The big rat pounced in the air, then immediately twisted its body, fled again, and pounced on Su Yuan. The momentum clearly regarded him as prey.

Su Yuan didn't want to get entangled with this big rat, so he raised his right palm and sent a palm in the air.

Bang!

The big mouse received a slap in the air, let out a strange cry, and rolled its body several times in mid-air before falling to the ground.

But after it landed, a pit was sunk in the middle of the big mouse's palm, and blood overflowed. However, it did not die. Instead, it struggled on the ground for a few times before getting up again.

Su Yuan couldn't help but frown when he saw this. The volleying palm he sent out just now was very powerful. Even a martial artist at the level of Martial Master couldn't withstand this blow.

But the big rat managed to hold on. Even though it was injured, it was still able to struggle to get up. Such a strong defense was comparable to that of a ferocious beast!

After getting up, the big rat seemed to be afraid of Su Yuan. It did not attack him again, but raised its head and let out a few weird screams, "Creak... squeak... squeak..."

Following the scream of the big rat, more than a dozen black shadows emerged from the depths of the tunnel and quickly gathered in this direction.

When Su Yuan looked over, he saw that there were more than a dozen mice of about the same size!

Obviously, these dozen big rats were summoned by the injured big rat.

If you can't beat him, shake the rat. This big rat is quite cunning.

squeak squeak...

More than a dozen big rats gathered around the injured big rat, making piercing screams from time to time. They looked as if they were discussing something.

About ten seconds later, the dozen or so big rats suddenly dispersed, and then gathered into groups of three. They were divided into four groups in total, and then stared at Su Yuan with "eager eyes".

Zhizhi...zhizhi...

The four groups of rats exchanged information, and then two groups of them rushed towards Su Yuan.

The other two groups took a circuitous approach and quickly circled behind Su Yuan, forming an outflanking formation.

Su Yuan was shocked, these big rats could actually "form up", their IQs were really not low!

Whoosh whoosh whoosh…

Four groups of big rats attacked Su Yuan at the same time!

Su Yuan hurriedly used his "flying" magical power and jumped up, suspended in mid-air.

squeak squeak...

The four groups of big rats immediately jumped into the air. They all raised their eyes to look at Su Yuan in mid-air, and let out a series of ear-piercing screams.

Su Yuan didn't want to get entangled with them anymore, so he volleyed downwards and fired more than a dozen palm thunders.

Boom boom boom…

The dozens of palm thunders, armed with thunder and lightning and powerful force, instantly blasted the dozens of big rats to pieces, with black smoke rising from their bodies.

The dozen or so big rats fell to the ground and struggled a few times before dying one after another!
