Entering the gate, it was an ordinary hall, and a cylindrical elevator with transparent material appeared in front of the two of them.

When the two entered, they descended at a terrible high speed. Outside, it's pitch black.

After a full 30 seconds, Tang Lang's estimate had at least dropped more than 500 meters, and the eyes of the two suddenly lit up.

The "Merry Genius" was moved by the integrity of his heart to the tears that contained the entire eye socket, and he couldn't help but shed it at all, and tears flowed down his cheeks. This made Tang Lang, who was also shocked by the scene in his eyes, feel less bad for him, no matter what, this guy is quite emotional.

Sensual people generally can't go there, because deep down in their hearts, they have their own soft places. And the more rational people are, the harder they are, they are suitable to be colleagues, but not friends. Just as the kings of ancient times called themselves lonely and widowed. As for the sensual emperor, he generally doesn't last long, unless he is lucky.

It's a space of incredible depth and expanse. It is high, at least tens of meters, and even the elevator that descends at high speed takes several seconds to land. The countless lights overhead are like stars, illuminating the huge space, and the width and length are even more incomprehensible, according to Tang Lang's estimates, there is at least a huge area as three or four football fields.

The two of them stepped out of the elevator and were in this huge space, and they had a sense of insignificance for no reason. But what makes the two of them feel even more small may not only be because the secret space under the ground is unimaginably large, but that in this space, countless scientific and technological achievements of their predecessors are densely placed. In every shop window and exhibition position, there is a dazzling array of everything.

Tang Lang has seen the federal arsenal, dozens of mecha standing quietly, and he has also experienced the big battle with air pirates, the charge of hundreds of mecha is like destroying the world, but compared to the mecha here, it is completely pediatric. Not to mention the wide variety of mechas, not to mention what scientific development path is recorded, in terms of quantity alone, it completely kills the number of mecha that Tang Lang has ever seen, and there are at least a thousand mechas.

At this moment, Tang Lang was not a student, but a warrior, and he instinctively analyzed combat effectiveness by quantity.

Seeing Tang Lang's blank gaze on the large number of mecha with different shapes, the "Merry Genius" who wiped away the tears on his cheeks without showing a trace regained his arrogance as a senior professor, and said disdainfully: "It is rumored that there are the earliest models of mecha since the founding of the Federation here, and the latest mecha that has not yet been put into active service, as well as the collection of mecha of various countries and eras in the starry sky, and it is normal to have a large number." ”

"How many are there?" Tang Lang subconsciously asked.

“。。。。。。” Lao Wang was asked a little speechlessly, is it the first time for Lao Tzu to come? You're more annoying than that old fellow Edward!

"Rat-eyed!" Lao Wang reprimanded. "The advanced laboratory is not a professional mecha laboratory, the mecha is only a small part of it, young man, your vision should be broader, in this ocean of wisdom of predecessors, you can see the light of wisdom that you usually unimaginable."

As far as the facts are concerned, Lao Wang is really not wrong. At first glance, the large number of mechs is only a small part of the vast space on display. Starship power plant like a hill, the formidable starship energy cannon, the star fighter with a length of more than ten meters, the sci-fi all-terrain vehicle, the rotorcraft, the huge mechanical arm, the high-end lathe。。。。。 The crystallization of a wide variety of science and technology, even if the mind is as firm as Tang Lang, it is also extremely shocking.

This is also the first time he came to this starry sky, and he deeply felt that he had come to a future world, and he was really an indigenous from 4,000 years ago. It's really dirty buns!

"I still need a while to finish, Xiao Wang, you take Xiao Tang for a walk!" Professor Edward's voice came at the right time.

Lao Wang involuntarily jumped on his forehead, except for those old men in the future, whoever calls him Xiao Wang is in a hurry, he will have to call him Lao Wang in the future, even if it is next door.

Shopping and eating is the patent of girls, but for an old man and a little man who are both physically and mentally shocked, shopping and watching is a must.

Although the two of them were unhappy with each other, as a tutor of the academy, they had the consciousness of taking care of the "safety" of the palace of knowledge. Tang Lang doesn't care, although Lao Wang is annoying, but his talent is leveraged, he can tell that he is ugly and ugly, and he just uses it as a tour guide, as long as he ignores his increasingly stinky face.

Why is it so big in heart, just touch whatever stuff you want, especially he, a senior professor, doesn't dare to be good! Why didn't an armed robot pop up and beat you into meat sauce! Lao Wang watched Tang Lang tap on the mecha and power engine countless times, and this ambition would pop up in his mind.

"Don't mess with that electric turbine!"

"Don't move that mecha, don't press it indiscriminately, it's the first generation of keyboard button control mecha thousands of years ago, and now there are only five left in the whole federation, if you break it, you will pay for it?" Stay away from it! ”

"Bastard, don't move that robotic arm! That's the fifth-generation individual maintenance robotic arm, an epoch-making product! ”

"My dear mother! Hurry up and put it down, it's an antimatter bomb, if it is detonated, not to mention that the entire academy will have to be blown up into space! Lao Wang's face turned a little pale at that moment, and even the vernacular of his family popped out.

。。。。。。

Facing the ignorant guy in front of him, Lao Wang, who had been angry all the way, finally collapsed completely after Tang Lang looked at a basketball-sized metal ball.

He was completely afraid of the ignorant and fearless Tang Lang. As a senior professor, Lao Wang didn't dare to take chances with his predecessors, and those who wanted to achieve something in science had to have a kind of "madness" that ordinary people did not have, and the probability that the antimatter bomb could be detonated was definitely greater than 50%. Including these mecha that exist underground, Lao Wang is sure that once there is a war here, even those old antiques, as long as they put in energy crystals, they can be activated to become killing machines, not just become exhibits here.

And that's not just speculation. A hundred years ago, because of the intervention of the Great Eagle Empire, when the Federation encountered a major crisis, the Academy Management Committee issued an order, led by thirty mentors, and thousands of outstanding students who were selected to respond to the establishment of an independent mecha division of the Military Academy to prepare for the war.

Although these scientists of the Federation are antique, they are by no means pedantic, their homes are almost gone, and they still want to engage in wool in the palace of knowledge? As long as the home is still there, everything will be there again. Otherwise, leave the good to the enemy?

"Let's go and visit the technology of the Ancient Blue Star Era! Take a look at the ancestors. At this time, the "Merry Genius" pulled the interested Tang Lang in an almost pleading gesture, just begging him not to harm these high-tech crystallizations.

For Lao Wang, although the ancient objects that have gone through thousands or even tens of thousands of years in the Ancient Blue Star Era are more precious, at least those will not explode! Moreover, the items filled with an ancient atmosphere will give people a kind of admiration from the depths of their souls because of the solemnity of the years, which should make Tang Lang's goods a little more restrained.

As Lao Wang thought, the rust of the bronzes left by the Xia, Shang, Zhou, Spring and Autumn Warring States period was mottled with the vicissitudes of time, and Tang Lang did not do it for the first time, but just stared with his eyes. The Tang knife is still sharp, the Song clothes are as gorgeous as ever, and the tiger squat cannon from the Ming Dynasty shows the wisdom from the ancestors of the Chinese people.

Until, Tang Lang walked in front of an exhibition stand, stopped and stared for a long time, and there was a trace of something in his eyes that made Lao Wang a few meters away inexplicable. It was the light weapons display stand of the 200s before the first ephemeris year, and it was still the era of gunpowder-driven live metal ammunition.

Then, Tang Lang stretched out his hand, took out one of the more than two dozen guns in the display case, and carefully looked at it in his hand.

"Hey, that's an antiquity from thousands of years ago, why don't you have such a long memory, put it back!" Lao Wang's subconscious "roar"!

Then, his voice gradually became smaller, as Tang Lang raised his head to look at his gaze.

In Tang Lang's eyes, there was a trace of crystal that made his heartstrings tremble for no reason.

It is undeniable that Lao Wang doesn't like Tang Lang, not only that Tang Lang is a "back protégé" because he is taken care of by Professor Edward, but he also doesn't like Tang Lang's appearance of being neither humble nor arrogant in the face of him. It was as if he was Xiao Tang, and his senior professor was the Xiao Wang in his eyes, which somewhat frustrated his self-esteem as a mentor.

But no matter how much he didn't like it, Lao Wang had to admit that Tang Lang was definitely an excellent soldier, and the scene when he forced an intermediate and second-level mecha division back with his fists almost showed that he must be a soldier of a hundred battles on the battlefield. At least, Lao Wang, who is an intermediate second-level mecha master, knows in his heart that even if it is him, he will never be able to do better than Zhou Jinjin.

But why is such an excellent soldier holding a gun that is thousands of years old, so emotional?

"Mr. Wang, do you know what this gun is called?" Tang Lang rubbed the body of the gun with his hand, lowered his eyelids, and asked in a low voice.

He thought he could forget his hometown, but after he picked up this extremely familiar gun, it poured into his mind like a tide, the grass and trees in his hometown, the ten years in the southwest, the father who had been asleep, the gentle eyes of the sister, and the little nephew waved his hand to say goodbye to the white and fat little hand, which was extremely clear.

"This, there is an introduction above!" Lao Wang wants to be crazy a little, he is not a weapon book, knowing the changes in weapons in the past few hundred years is very amazing, who remembers thousands of years ago?

But as a teacher's pride, he couldn't let him say a word, so he could only click on the virtual screen on the stage, which clearly displayed the model "81" of this automatic gunpowder driven metal live ammunition rifle.

"What you said is just a model, in fact, it was in the army at that time, called 81 bars!" Tang Lang shook his head and muttered to himself.

Sure enough, the one who can't go back is the hometown!

The sparkle that no one can glimpse under the lowered eyelids, the thicker it is!
