Tang Hao didn't feel that he was the future of mankind at all, at least the future of mankind should not be sitting motionless on a stone chair like him, and even the most basic freedom was lost.

"Adjutant, what do you think the world on the ground will be like?" Tang Hao recalled the various materials he had collected before: "Does human civilization still exist?" Are our efforts still meaningful? ”

The adjutant replied, "As long as humanity exists, human civilization will not perish. ”

"Any intelligent race has evolved from the most basic small organic molecules through hundreds of millions or even billions of years."

"During this period, life has been devastated countless times, but as long as you survive, you have the opportunity to continue to evolve and develop."

"Now at least in this underground world, there are still humans in this world, even if all humans are wiped out except this planet; Even if the ground is really barren, all traces of human civilization have been wiped out......"

"As long as humans exist, they can set sail again, and it will take thousands, if not tens of thousands, of years to climb the mountain again."

Its words were very motivating, and even Tang Hao listened to them with enthusiasm.

"Very good, the revival of human civilization begins with our little 'journey to the underworld'!" Tang Hao said proudly: "We not only want to return to the ground, but also fly to the sky, go to space and other planets, and regain the position of human beings in the universe!" ”

……

Tang Hao's second Form 2 speech did not affect the progress of the "Journey to the Underworld" team.

After installing the "subspace warehouse" with a mobile barrier, their task on this level is completely completed.

Now there are a total of 20 Gatling gun trucks, 20 electromagnetic kinetic gun trucks, as well as 10 transport vehicles and this mobile barrier, which has completely completed the process of full mechanization.

Each member of the group had their own vehicle, and they were able to rest with the workers in the mobile barriers, and even the slaves were paid a higher salary, and they could sit in the passenger compartment towed by the transport cart and move with the large army.

Once everything was ready, the Journey to the Dead and all the members of Sector 14 were ready to leave the machine building factory and head to the central core to begin their march to the upper level.

"Eh, Mamba, why don't you give your mobile barrier a name?" Freya asked, looking at the heavily armed man.

The corners of Mamba's mouth twitched, naming such a thing has always been a shortcoming of some mysterious power, and he was worried about what a strange name this mobile barrier would have.

Freya said to herself: "Why don't I think of one for you, you see, our mobile barrier is called the 'Iron Bull', and your force value is higher than ours......"

She thought for a moment and said, "Why don't you call it the Giant Rhino?" What do you think of the name? ”

"Good!" Before the mysterious power appeared, Mamba immediately clapped his head.

Although the name is a bit rustic, at least within the acceptable range of normal people, in order to avoid a more bizarre name, Mamba immediately announced this decision to all members in the spiritual network.

Anyway, it's already a done deal, and it's impossible to change it.

Everyone was relieved to hear the name, and it seems that everyone has PTSD about the name.

……

With the sound of a mechanical turn, the journey to the upper floor finally began.

Tang Hao looked at the steel giant beast with six mechanical legs, and he also sighed in his heart that the progress of the "Journey to the Underworld" was really too great.

The "Iron Bull" of the 14th District of the "Boom Boom Boom ......" followed the "Giant Rhino" and also started a new round of migration.

This time, with the help of the "Journey to the Underworld", Freya and the others no longer have to pull the heavy city walls to set off, and the children are driving multi-legged chariots around the "Iron Bull", and the strength of their team should not be underestimated.

The "Giant Rhino" was also surrounded by a large number of multi-legged chariots, and walked towards the core hub step by step.

Looking at its heavy armor, lined barrels, and very textured body, Tang Hao sighed: "This big guy looks a bit steampunk, but ...... There are some big chimneys that emit black smoke, how do you say that? ”

"How riveting and steaming just ......" Tang Hao recalled the stalk of his original world, and laughed happily: "...... Turret supremacy! Billions of turrets, billions of glory! ”

The intelligent adjutant of the base came over very inopportunely: "Your Excellency Commander, please forgive this machine for disagreeing with each other, although the multi-turret structure has different opinions, but the riveting technology has obviously been completely abandoned by the times......"

"In the embryonic stage of nuclear power reactors, steam power barely exerted a trace of residual heat, and then it was swept into the garbage heap of history......"

"As for the rigid suspension, both wheeled and tracked combat vehicles have been withdrawn from the stage of history, and there is no need to discuss it."

Tang Hao rolled his eyes, and cursed this guy who was terrible in his heart: "You said you were fat, and you still gasped!" ”

……

Lias's reconnaissance team was the first to reach the core hub, which was so barren that there were no lit lampposts and it was pitch black.

Following the light of the chariots, the convoy cautiously moved through the darkness, having already probed the area and found no threat, but Lias kept everyone on their toes.

A tunnel leading to the dome slowly appeared in front of everyone, and compared to the core hub of the "fortress" city, this pipeline looked as if it had been abandoned, and there was no light from the inside out.

"Car No. 2 and car No. 3, enter the alert position, please answer when you receive it!" Lias pressed the call button.

He's wearing a multi-purpose suit now, but it's okay, but this mask is a bit of a hindrance, and he always likes to lift it when he's fine.

The other two vehicles quickly responded, and three vehicles were scattered around the core hub, ready to prepare for the arrival of the large army.

The footsteps of the "Click......Click" and "Giant Rhino" came from a distance, and its high-powered light dispelled all the darkness, and everyone was able to see the whole picture of the core passage.

"Uh, Freya, are you sure our core passage is working properly?" Susie looked at the dark and broken vertical passage in front of her, a little worried.

The voice of Freya, the leader of the Iron Bull, came from the communicator: "Don't worry, Susie, although this pipeline is rarely used, it can still connect the upper, middle and lower worlds, but we have to pay them a little in advance." ”
