"Speak up! What are your thoughts after hearing what Barrett Walker said just now?" Prag Leo seemed to have grasped something in his heart upon hearing Barrett Walker's words. After pondering for a while, he asked expressionlessly. At this moment, he no longer had that condescending air. After all, the onlookers see more than the players, and Barrett Walker's words might open up new horizons for his research. Barrett Walker couldn't tell him that these things were only brought up by people years later, and those people were stuck in dead ends. As long as they found a way, they would quickly find a way out. Barrett Walker could only give some hints on the side. Under the scrutiny of everyone, he slowly said, "The most important issue I think about mechs is the issue of power. Currently, electricity is widely used, mainly from bioelectricity provided by humans entering the Second World. This is the greatest invention in the new mythological era, which not only willingly confines humans but also provides power for free. The power provided by the electric motor is simply insufficient to drive the mechs. According to some of Tesla's principles, electricity can be wirelessly transmitted as energy. Of course, the public, including me, is not aware of these things, and I'm afraid you are very clear about this. The biggest problem for not going in this direction is that the electric motor cannot provide such powerful power. Even if it is solved, transmitting electricity is very dangerous for the people inside the mechs." "The only way is to go in another direction, that is, nuclear fusion. Even airplanes can fly in the sky. This is the mainstream! Nuclear energy can provide such powerful power. However, trying to miniaturize the nuclear reactor, with the current technology, bombarding the uranium-235 nucleus with neutrons from the outside, the possibility is very slim! But have you thought about using something else to replace it, have you? And this thing can be done without demanding conditions..." Barrett Walker talked at length. Of course, all these things were several years later. However, he didn't know if this alien invasion would ignite the fuse of the end of the world a little ahead of time, so he also needed to make a contribution to the future of humanity to compensate for the guilt in his heart caused by changing reality. After all, at the end of the world, the deaths are not just one or two people, but everyone is in danger of being wiped out. Prag Leo's hands trembled, and his eyes looking at Barrett Walker became even more fanatical. While everyone on the side was worried about what might happen, he said, "Never mind these people, let's go! Let's go to the mech workshop to take a look!" As soon as he said that, the arm that had just thrown Barrett Walker out aimed at the empty wall. There was a rumbling sound in the place where the robot had just appeared, and a huge passage suddenly appeared, as if a machine was running. Barrett Walker took a look inside. This scene was so familiar. Wasn't this the huge machine he had seen before he fell into the sword mound? Looking at the spacious and huge walls inside, Barrett Walker's eyes were full of shock. How much manpower and material resources would be needed to create such a large space and such a large machine system? Prag Leo observed Barrett Walker and saw that he indeed had a shocked expression, and his face showed a pleased look. Walking on the steel corridor, there was a huge open space below. Looking down from the center of these huge gears, Barrett Walker couldn't see to the bottom at a glance. If this place wasn't too high-tech, Barrett Walker would doubt if it was a miracle. "Is nuclear energy used here?" "It's not nuclear energy! It's an energy from a cosmic meteorite, which is equivalent to nuclear energy! However, it's more advanced than nuclear energy and can even reverse gravity. Going downstairs will feel like going upstairs. I've been studying it for a long time and still haven't figured out what kind of energy spectrum it is." Barrett Walker knew that there was a theory that said all matter appears in the form of waves. For example, light is composed of photons, which are also a kind of continuously moving wave. Hearing him say this, it was obvious that this energy method had gone beyond the understanding of objects on Earth. However, in this day and age, even alien monsters existed, so there was nothing strange about it. But it brought up a very serious question: "Why can't this energy be used by the mechs?" "I wish I could, but this energy is too huge and very unstable. It could explode at any time," the old man said somewhat dimly.

Barrett Walker fell silent for a few seconds, surprised that they had already thought of using alternatives. Perhaps his words would not be valued, as he was considered ignorant in comparison to the others. After all, three mediocre minds could surpass one exceptional mind, and sometimes an offhand remark could suddenly enlighten them. Therefore, Barrett Walker refrained from speaking further, so as not to risk ridicule by saying too much.

Walking along the steel corridor, Barrett looked down into the darkness below, feeling a powerful sense of awe. The sight would likely cause vertigo in those with a fear of heights, but seeing the calm demeanor of the scientists, Barrett couldn't help but admire them. After crossing the unobstructed sky bridge, he entered a room filled with machine parts.

In the distance, rows of mechs hung on the assembly line, motionless. Barrett's excitement surged at the thought of these machines surpassing all others and becoming a tool of attraction. However, if the nearby professors knew his thoughts, they would likely be furious and reprimand him with a wrench to the head.

Observing the fully assembled mech, Barrett noted that it was not the usual satellite generation tracked mech. It stood nearly three meters tall with very thick legs and a compression column between them, along with a dozen various colored wires. The proportions of its arms and legs were disproportionate, but Barrett assumed that it possessed considerable strength. In its center was a narrow space.

This awe-inspiring mech, which could be ranked alongside women, immediately captivated Barrett. He let out a cheer, then quickly rushed over and ascended the stairs in front of it. Peering inside through the transparent cover, he asked eagerly, "This mech can be activated once it's assembled, right? How do I start it?"

"Hmph! You truly are a student," said Pragg Leow, with pride. This was his masterpiece, containing two independent power systems, an intelligent auxiliary control system, and a fully intelligent operating system. The countless components could probably build two of the latest combat machines.

Pragg Leow also approached the mech, caressing it as if it were his own grandchild, his face filled with affection. Suddenly, he solemnly commanded, "Double happiness! Start!" Then he stepped back, and the mech suddenly moved, followed by the illumination of the operating system inside the transparent cover.

Barrett watched with ecstatic joy, feeling several times more euphoric than a climax.
