"Boss, what is this?"

Looking at the passage in front of him, Lan Gang was very puzzled, before falling asleep, he had been living in this city, and he knew everything clearly, but he never knew that there was a tunnel here.

Jin Yang shook his head:

"I don't know what's going on, let's see first"

As he spoke, he stepped forward to the edge of the cave.

The entrance in front of me is 20 meters wide and 15 meters high, rectangular, with walls, tops and floors on both sides, flat and smooth, as if it has been specially polished.

"This is definitely not an ordinary mine, an ordinary mine will be reinforced to a certain extent at most to prevent the underground from collapsing, and it is impossible to build it so luxuriously, because it is not necessary."

Looking at the tunnel in front of him, Jin Yang thought in his heart that he had an intuition that this passage was definitely not as simple as it seemed.

After thinking for a while, Jin Yang turned to the group of autobots and said:

"Let's go and see together, and be vigilant."

After saying that, he carried the energy gun into the tunnel in front of him, and the other Autobots were also aroused, and they took the energy gun in their hands and walked into the tunnel one after another.

The passage was pitch black and there was no light, but fortunately, the Autobots' eyes had an infrared scanning function, which did not affect the line of sight.

Jin Yang led nine Autobots to search forward along the tunnel that continued to slope downward and spiraled inward.

However, a group of Autobots walked in the tunnel for two hours, conservatively estimated to be several kilometers underground, and the road ahead was still with a large curved corner, empty as if there would never end.

"Boss, how long are we going to go?" The bumblebee behind him was a little impatient and asked impatiently.

"I think it's better to go back, leave the castle early, our safety can be guaranteed"

Walk in the middle of the warhead, put forward your opinion.

"The nearest Decepticon base is more than 1,000 kilometers away from here, plus the time for the dinosaur bird to return, there are no three days that we can't arrive, we have enough time to evacuate, explore the tunnel in front of us first, don't worry."

Jin Yang said as he walked.

Let him return, isn't that a joke? The passage in front of him was full of mystery, as if it was deliberately hiding something, and in his opinion, no one would be bored enough to build an underground tunnel that would not have the slightest effect, and since it was done, there must be a reason for it, maybe he could find something good.

"I hope to find something good", Jin Yang thought with some expectation.

Another two hours have passed, a group of autobots have gone deeper than ten kilometers underground, the tunnel still has not come to the heart, the Weilong Weimeng brothers and electromagnetic waves, have long been full of complaints, if it was not for Jin Yang to suppress it, it may have been a trouble, even Jin Yang's confidence has been shaken.

Just as he was considering whether to continue walking, the environment ahead suddenly changed.

"Hey, what ...... this?"

Jin Yang, who was walking in front, suddenly stopped and looked ahead in a daze.

The bumblebee who was walking behind, seeing that Jin Yang stopped and didn't leave, couldn't help but wonder:

"Boss, what are you looking at?"

"Come and see, too"

Jin Yang took a few steps forward, got out of the tunnel, and said to several Autobots behind him.

Behind him, Bumblebee, Lan Gang, as well as warheads, antennas and other Autobots, followed out of the tunnel, and when they saw the scene in front of them, they were all stunned.

I saw that at the end of the tunnel, an underground space with a radius of several kilometers appeared, of course, this is not the point.

To their amazement, in the central area of this vast underground space, there was a boxy platform.

The platform is about two kilometers wide and hundreds of meters high, and the entire body is made of metal, and the shimmering light on the surface can be seen under the reflection of infrared rays.

Above the platform, there are some strangely shaped buildings, giant mechanical arms with a diameter of more than ten meters, bridges made of metal gears, very sci-fi towers, and cylindrical objects that glow with ghostly lights, all of which look very chaotic and disorderly. However, when these strange buildings, when connected with the huge platform below, they exuded a majestic and heavy atmosphere, as if the two capitals were originally one, which brought great shock to Jinyang.

His eyes were staring at this strange "building", and the more Jin Yang looked at it, the more he felt, it was like a fortress, the platform below was undoubtedly a bearing base, and the dark columns were clearly cannon barrels, and the thick caliber was definitely not small.

"It's just that why is this battle fortress built underground, and not on the ground?"

Jin Yang was very puzzled in his heart.

Soon, a group of Autobots came under the platform.

Coming closer, Jinyang can feel the majesty and grandeur of this fortress even more, the side of the base is 90 degrees perpendicular to the ground, and the whole body is composed of a piece of metal 100 meters high and two kilometers long, as if a huge city wall is horizontally ahead.

Looking around, Jin Yang didn't find anything that could provide climbing over, so he beckoned Wei Long to come over and instructed them:

"Go around this fortress and see if there is any way up."

Hearing that there was work to do, the two brothers of Weilong and Weimeng hurriedly patted their chests and said:

"Boss, you can take a look, our brother will take care of the ...... who has done this beautifully."

Jin Yang's eyes glared, "Don't talk nonsense, don't go soon."

When the two brothers saw that Jin Yang was angry, they instantly shut up, and immediately transformed into two cars and drove forward along the edge of this fortress.

Jin Yang and the other autobots waited in place for more than ten minutes, and the two brothers came back one after another.

Under the gaze of the autobots, Wei Long hung his head and said:

"I couldn't find my way up here."

The mighty man next to him also said:

"I don't see it either."

All the Autobots were dumbfounded, so high, how could they get up without a road?

Jin Yang was very helpless in his heart, a height of hundreds of meters is equivalent to a thirty or forty-story building on the earth, and without climbing equipment, even a Transformer can't climb it, unless he has the ability to fly. It's a pity that none of the Autobots in their group are airplanes.

"Do you want to give up? Absolutely impossible, if you don't get something good, buddy won't leave today"

Jin Yang didn't believe that a wall could stop him, if he wanted to say a way, it was not nothing, dig some earth and stones from the side, pile up a slope in front of the fortress, and naturally he could go up.

It really doesn't work, you can dig a row of holes in the metal wall as a place to put your feet, and then use these holes as a ladder to climb up.

Of course, without figuring out the situation, he didn't want to use the second method in order to try to make some unexpected changes.

Just as Jin Yang was about to discuss with the other Autobots how to solve this problem, the bumblebee beside him suddenly took a few steps forward and came to the base of the fortress.

Then, in the stunned eyes of all the Autobots, he clenched his fist with one hand, mustered all the strength of his body, and smashed his fist into the metal wall in front of him.

"Knock ......"

The sound of bells like morning bells and dusk drums buzzed in the underground space, and even the surrounding ground was faintly shaking, as if an earthquake had occurred.

The sudden loud noise startled all the Autobots, and they were almost knocked to the ground, and the Autobots who came back to their senses glared at the bumblebee angrily, and it was obvious that his collision behavior made everyone very dissatisfied.

The bumblebee also seemed to know that he was in trouble, so he couldn't help but lower his head and pretend to be an ostrich.

Jin Yang was also frightened by this terrifying voice, and was about to say a few words about bumblebee, but at this moment, from the metal wall in front of him, there was a piercing sound of gears tumbling and rubbing against metal.

Immediately afterwards, the metal wall began to vibrate slightly, and in a "crunch-crunch" sound, a wall close to the ground began to bulge outward, slowly protruding a metal brick 10 meters wide and 1 meter high. Over time, the raised bricks slowly move forward on the ground and stretch longer and longer.

Then, above the first metal brick, another metal brick protruded.

Then came the third, fourth, fifth, and more and more metal bricks protruding from the walls, forcing the onlookers to retreat to make way for the metal bricks in front of them.

A minute later, between the fortress and the ground, there was an additional staircase 10 meters wide and 45 degrees upward.

Jin Yang, Lan Gang, Warhead and other Autobots looked at each other, "This is okay."

As the bumblebee that caused this mutation, he scratched his head embarrassedly, his eyes full of surprise.
