Finally, when the elevator was descending to the 5th basement floor, Mitsuo Akisawa pressed the stop button and immediately opened the door of the elevator.

Ming Ze Guangnan was the first to walk out of the door of the elevator, and Alida and Ning Lei in the back also cautiously followed.

However, the corridor was pitch black, and nothing could be seen, and although Alida had a small oil lamp in her hand, the area that could be illuminated was really limited.

Under such conditions, how could it be possible to quickly find the main control room that controlled the entire fortress?

And if you can't find the main control room in a very short time, those biochemical Japanese soldiers who were attracted away by Gu Xiaole may come back at any time!

Won't the time come to waste?

"Papapa......" Suddenly in the dark, Mitsuo Mingze didn't know what switch he had touched, and then in the entire corridor where he couldn't see his fingers, the electric lights on the walls lit up one by one, and the entire five underground floors were also illuminated.

It seems that the experience of living in an underground fortress for many years has made these biochemical Japanese soldiers accustomed to the dark environment where there is no light.

Alida took a closer look, and found that in addition to a few rooms full of motors and equipment in front, there was a room in the back that was significantly larger than the other rooms, only to see that Ming Ze Mitsuo moved his somewhat rickety body and slowly led them to the front of the large room, although the paint of the door had long been oxidized and peeled off, Alida pushed the door hard and locked it tightly.

Mitsuo Akisawa used his long fingernails to scratch the paint on the door, making a "creaking ......" sound that made the eardrums collapse.

"Stop, stop...... Xiaolei, don't let him scratch again!" Alida quickly covered her ears and said.

Ning Lei was also uncomfortable when she heard this, and hurriedly walked behind Mitsuo Ming Ze and said: "すみません、マスター室は鍵で開けますか?" (Excuse me, does the main control room need a key to open?)"

The Mitsuo Ming Ze also seemed to be a little embarrassed by what he had just done, and hurriedly responded with their island people's signature nod, and stretched out his hand to invite Alida to come over and open the door.

Ning Lei glanced back at Alida, who walked to the main control room with understanding, took out the main control key of the fortress that had brought the little monkey gold back before, and inserted it.

Sure enough, the door of the "bang" electric control opened directly, and the rows of colorful instruments and switches inside were all exposed, and it seemed that they were obviously in the right place.

Alida and Ning Lei were overjoyed and hurriedly ran in, although the switches were marked in Japanese, but with Ning Lei translating on the side, Alida quickly found the switches to control several key departments.

Among them, the most important thing is to close the gate of the fortress, which is to connect the barbed wire fence around the fortress to 380 volts of high-voltage electricity, which is the key to whether they can defend against these biological and chemical Japanese attacks.

After doing all this, Alida breathed a sigh of relief, and just wanted to take Ning Lei and the three sisters of the Lin family back to the ground to see what the situation was now, but was suddenly stopped by Ming Ze Guangnan on the side!

He didn't know where he got a pen, and although his long nails twisted his fingers to hold it, he struggled to write on the wall beside him:

"地に戻らないでください。 Koji Ooda Daisakai が殺しました。 ”

Alida glanced at Ning Lei next to her in confusion, and the latter said with a slight smile:

"He's warning us not to go back to the ground, and he's saying Koji Oda will kill us!"

So that's the case, Alida nodded, it seems that this little soldier named Ming Ze Mitsuo has a really good heart, but it's a pity that he has been transformed into this kind of monster that is not a human or a ghost in this dark underground laboratory, and I am afraid that he will never be able to return to normal human society in this life.

"You tell him, don't be afraid, we have guns in our hands! In addition, we have already connected the surrounding power grid, even if that Oda Koji Daisa wants to come in, I'm afraid it won't be so easy!"

As she spoke, Alida symbolically waved the Chicago typewriter in her hand at Mitsuo Akirasawa.

After Ning Lei translated her words to this Ming Ze Guangnan, this guy lowered his head and seemed to fall into deep thought, and after a long time, he slowly nodded, and actually led a few of them back to the ground of the fortress in the elevator.

......

Of course, this is what happened just an hour ago, and the few of them returned to the observation room on the second floor of the military fortress.

Soon, Erida and the others found that Koji Oda had returned to the base with their strangely behaving group of biochemical Japanese troops.

The closed doors of the military fortress made him very angry, but he never expected that even the barbed wire fence on the outer wall was connected to high-voltage electricity!

Koji Oda, who was completely unaware of the fact that he was unguarded and was directly scorched by high-voltage electricity, and lost several imperial soldiers at once, that the main control switch of the power supply of this military fortress was in a building with five floors underground.

Even if that cowardly accomplice had the key to the main control room, it was unlikely that he would have been able to find it exactly in the underground building in a very short time, right?

"Could it be that the one I left behind, the one who didn't look like an imperial soldier, betrayed the empire and told those guys about the structure of the underground building of the fortress?"

Thinking of this, Koji Oda Osaku angrily opened his huge mouth at the fortress:

"Hiss...... Roar Roar Roar ......"

A strange low-frequency roar filled the entire fortress, and the little soldier Ming Ze Guangnan, who had been standing behind Ning Lei, suddenly covered his ears with his hands as if he had suffered some great injury, and squatted on the ground in pain and kept shaking his body......

"He, what's wrong with him?" Seeing that this strange-looking Japanese soldier suddenly changed his appearance, Lin Jiao, the little girl on the side, shouted in shock.

Alida and Ning Lei were also a little overwhelmed, after all, this kind of low-frequency sonic attack had no effect on normal humans like them, but from the actions of Ming Ze Guangnan, it could be seen that he was experiencing great pain at this moment.

Fortunately, this low-frequency sonic attack was not only effective against Mitsuo Akisawa, and the biochemical Japanese soldiers who were closer to Koji Oda and Osa were obviously suffering more severely than Mitsuo Akira, and after a while, the biochemical Japanese soldiers standing behind Osa all fell to the ground one by one, convulsing non-stop.

Seeing this scene, Koji Oda had to stop and continue to roar, and then angrily slammed the fortress wall several times before slowly kneeling on the ground in front of the fortress, like a samurai waiting for his opponent to appear.

After a full 10 minutes, the biochemical Japanese soldiers who had just been attacked by his low-frequency voice and were embarrassed climbed up one by one, and knelt outside the walls of the military fortress like Koji Oda.

Although they can't speak, their current actions are undoubtedly trying to tell the people inside:

We are ready for a long battle with you......
