"So, this prime minister's office has actually been around for many years?" Listening to the faint tremor sound above his head from time to time, Hao Yi shrank his neck, looked at the structure of this underground secret passage, and seemed to ask Erin who was leading the way in front of him casually.

It is an underground tunnel about five or six meters wide in diameter, which is connected to a secret prison under the Prime Minister's Office at one end. A thin layer of metal steel plate is inlaid with various pipes and sections of helium energy lamps. As Haoyi and the two walked over step by step, those helium lamps lit up on their own as if they were automatically inducted. However, I don't know if it's because it's been too long, the brightness of those helium lamps is obviously a little dimmer, and even some pipes are faintly oozing misty water vapor, and occasionally there are drops of water dripping down in one or two corners.

Looking at the shape of this secret passage, it looks like the tunnel built by the early interstellar migration of mankind.

"I don't know!" Erin looked down at a palm-sized terminal microcomputer in her hand, which seemed to show the holographic circuit map of this underground secret tunnel, and two flickering red dots, which probably represented her and Haoyi.

"It seems that this secret passage has existed since I was sensible!" Erin glanced back at Haoyi, flashing those big dark and innocent eyes, as if recalling childhood events, and said with a blurred look: "Even the current Prime Minister's Office seems to have been here at that time." At that time, however, it was a small three-story house, and the passage opened under it, and there was no messy prison cell. I remember that my mother used to take me down this secret passage and say why I wanted to hide from my father! ”

"Hide and seek?" Hao Yi was stunned and couldn't help but be confused. Even if an adult wants to play hide and seek, he won't use such a labyrinth-like secret passage. However, thinking that Bertlem was likely to still have the name of the leader of the *** underground shili back then, Haoyi suddenly realized a little in his heart.

Obviously, Erin's mother Monica's so-called hide and seek is actually hiding from the federal colonial Governorate and the like.

"Yes! That's how my mom coaxed me at the time! As she spoke, Erin's expression was a little gloomy, and her eyes with long eyelashes slowly drooped, as if muttering: "Now that I think about it, my parents must have had a lot of things to hide from me at that time!" ”

"Maybe they're scared of you!" Seeing this, Haoyi's heart softened, and he involuntarily comforted him.

Erin nodded a little understanding, then turned around, glanced at the map in her hand again, and continued to lead the way.

The terminal computer in her hand that recorded the map of this underground secret passage had been kept in the hands of Erin's mother, Monica. And just a few days ago, I don't know if it was the providence in the dark, Monica panicked for no reason, and it was a ghost who handed over the terminal microcomputer to little Erin and asked her to keep it well. Thinking about it now, maybe Monica had realized that the situation in Myrsa was about to change dramatically, and handed over the map of the secret passage to little Erin, probably like borrowing her daughter's hand to leave a way back for her husband Bertlem. However, Monica may never have dreamed that her daughter would use this secret passage to run away with a federal special operator who only had a few faces.

In addition to the terminal microcomputer in Erin's hand, the two of them each wore a set of individual light armor, Haoyi also held an assault rifle in his hand, and Erin also had a 9mm spike pistol pinned to his waist. The equipment was taken from the guards of the secret prisons.

After Erin commanded the guards to rescue Haoyi, Erin even made a shocking statement that she would take Haoyi out of prison. At that time, I almost didn't scare the guards to the point that their eggs were broken. And in order to prevent these guards from running to report to her father, Erin simply didn't do anything, of course, not to kill those guards, but to drive these guards to the small cell where Hao Yi originally lived and locked them up. Then, in the extremely complaining eyes of those guards, Erin took Haoyi away, found the entrance to this underground secret passage, and got in.

"Hey, Grandma, how long is this ghost secret passage?" Seeing that he had walked through another crossroads, Hao Yi subconsciously tightened the rifle in his hand, and looked at the other two secret passages where there was no trace of light, and he shivered unconsciously. This underground secret passage is not only old, but also has a continuous fork in the road, like an underground labyrinth. If it weren't for the secret passage map that Erin had in his hand, even if Hao Yi broke in alone, I believe he would not be able to distinguish between the southeast and the northwest, let alone find the secret passage exit.

Thinking of this, Haoyi had the idea of going back to Dalena, Hu Erpang and others. At that time, when Erin pulled him into the secret passage, he was thinking about rescuing Hu Erpang and the others. But Erin and the guards didn't know where Hu Erpang was locked up, and Bertreum could come back at any time, so if he continued to hesitate, I'm afraid that even Erin wouldn't be able to help Haoyi get out. In desperation, Hao Yi had to temporarily dispel his thoughts, and comforted himself in his heart and said that after he got out, he would try to come back and rescue Hu Erpang and others.

"I don't know!" Erin threw a sentence without looking back, almost making Haoyi stumble in fright.

"W-What? You don't know either? Well, auntie, don't tell me, you don't even know where the secret exit is! Haoyi suddenly had black lines on his head and stammered and asked. For this eldest lady who can often surprise people, Haoyi really doesn't dare to have any illusions.

"The map shows that there are several exits to this secret passage!" Probably something was wrong, Erin raised her hand and gently tapped the terminal microcomputer, while answering Haoyi casually. Her seemingly casual actions scared Haoyi's scalp numb. If something really malfunctioned with the terminal computer in Erin's hand, then the two of them might get lost in this labyrinthine tunnel.

"I've come in many times since I was a child, but basically every time my mother brought me in, and every time she took me out through the nearest exit to the Prime Minister's Palace, I really haven't been to the other exits!" Irene explained as she continued walking, "There is an automatic navigation function on the map, and I set the exit of the secret passage to the furthest exit from the Prime Minister's Palace, which should be outside the city!" ”

"......" Hearing Erin's words, Hao Yiden had the idea of rushing over and snatching the terminal microcomputer, God knows where this eldest lady who never knew how to write the word "afraid" would take him.

"Wait!" While talking, the two bypassed a fork in the road, Erin suddenly stopped and tilted her head to look at the terminal microcomputer in her hand for a long time, and then turned back to Haoyi to say hello, then ran to the side excitedly, opened a dark grid with a white arrow logo on it, crackling as if a password had been lost.

"Buzz!" The next moment, not far from Erin's side, a huge automatic door suddenly cracked.

"Come in!" Seeing this, Erin happily turned back to Hao Yi and said hello, and jumped into a secret room behind the automatic door. Hao Yi was stunned for a moment, and then hurriedly followed in.

After a bright helium lamp flashed, what caught Haoyi's eye was a small secret room the size of a basketball court. The secret room was densely packed with tarpaulin-covered things. The scene in front of him reminded Haoyi of the scene in the garage in Zhou Po's secret underground base at that time.

"I'm X, shouldn't this be a row of luxury locomotives too?" Hao Yi was stunned and lost his voice.

"Luxury locomotives?" Erin was also stunned by Haoyi's question, and immediately shook her little head like a wave drum, hid the terminal microcomputer in her hand, stepped forward and used her little hands to lift the nearest tarpaulin. A cloud of dust shook off along the tarpaulin, revealing a brand-new motorized airship.

"Isn't it!" Haoyi was suddenly stunned.

"What isn't? It's all jet ships! Erin seemed a little dissatisfied with Haoyi's lack of joy, and muttered, "My mother and I both like to drive motorboats, so my mother simply asked my father to build this garage here." There are all kinds of jet ships hidden here! You see, this is the latest MAP2 motorboat, which is said to have just been launched on the market. And this one, the UP23 airship, is so fast that it can almost catch up with the latest sports cars! ”

As she spoke, Erin lifted the tarpaulins one after another, revealing different styles of motorized airships. And Erin actually introduced the performance of these motorized airships to Haoyi one by one, etc., and talked about how she learned to drive an airship with her mother back then.

"They say that there is a father and a son, and of course, a mother and a daughter. It is conceivable that this eldest lady's mother is definitely a ruthless character! While listening to Irene's explanation, Haoyi secretly reached out and wiped the cold sweat on his forehead, and involuntarily sketched the glorious image of Erin's mother Monica in his mind.

"Boom!" Just as Erin was frowning, there was a faint tremor overhead, and patches of crushed lime were shaken off from the cracks in the steel wall.

"Who, what the hell do you think is going on? Does anyone really want to go against my dad? This abrupt movement made Erin subconsciously stop explaining the performance, looked up at the steel ceiling with a slightly pale face, and asked Haoyi in a snort.

In Erin's concept, her father was already the head of the entire St. Prolius district, and it was almost impossible for a second person to oppose her father except for her daring to bare her teeth. However, more than ten minutes ago, the faint sound of explosions outside seemed to make this thought in her heart slowly begin to waver.

"Don't think about it, grandma, let's run away! Maybe, your dad has already sent someone to slap us in the back! Hao Yi took advantage of the fact that the eldest lady had finally stopped temporarily, hurriedly stepped forward, picked a motorcycle airship casually, and after touching the switch button and driving program three or two times, he started it violently.

"Hey, wait for me!" Seeing Haoyi driving an airship and swooping out of the garage, Erin came to her senses, hurriedly stepped onto an airship, and flew out.

After about half an hour, the two finally reached what Irene called the furthest exit from the Prime Minister's Office. However, when Erin opened the exit door, Haoyi was suddenly shocked by the scene outside, and his jaw fell to the ground......
