After the air defense identification system was installed, Su Buyan and Xia Chujian returned to the first floor and began to repair Liu Shun's mechanical head.
Liushun's hemispherical mechanical head was just the shell, which was broken, and the eye display screen on the shell was also damaged.
This level of repair is a piece of cake for Su Buyan.
In order to prevent the same thing from happening in the future, Su Buyan used glass stone as the eye display screen, and then used special metal composite titanium to remake the mechanical head shell for Liu Shun.
"Glassstone has an ideal two-dimensional crystal structure, extremely high electron transmission capabilities, strong thermal conductivity, and is even harder than composite titanium. It's the material used for visual shields on interstellar battleships."
"Compound titanium is a special metal, an order of magnitude stronger than conventional metals. From now on, let alone being squeezed by an elevator car, even a punch from a regular mecha wouldn't hurt its head."
Su Buyan said proudly while replacing Liushun's head shell.
Xia Chujian was watching from the side and asked casually, "What about mechas that are higher than ordinary levels?"
Su Buyan glared at her and said, "If Liu Shun offends a mecha higher than the ordinary level, it would be more convenient to return to the factory and rebuild it!"
Xia Chujian didn't care about Su Buyan's attitude at all. She smiled and said, "Actually, I think ordinary-class mechas are pretty good. I've practiced with ordinary-class mechas in the Special Security Bureau. They're over three meters tall, and the built-in sniper rifle is really cool!"
Su Buyan said, "Only three meters? That's indeed an ordinary type among conventional mechas."
Xia Chujian was curious: "Besides the ordinary type, are there other types of conventional mechas?"
"Of course there are!" This was Su Buyan's area of expertise, and he immediately began to talk non-stop. "There are also medium-sized mechanical mechas, which are six meters tall. Advanced mechanical mechas are fifteen meters tall. The highest level of conventional mechas is the interstellar mecha, which is one hundred and fifty meters tall!"
Xia Chujian exclaimed in surprise, "There's an interstellar mecha among the regular mechas?! It's actually 150 meters tall! - Is it for humans to pilot?!"
"Conventional interstellar mechas are also mechanical mechas, but they have requirements for mental strength. If your mental strength is below level S, you cannot drive an interstellar mecha." Su Buyan said, pulling out the virtual display screen of his quantum optical brain and showing Xia Chujian the types of conventional mechas he had just mentioned.
Xia Chujian only then realized that the ordinary conventional mecha that he had always been so proud of was nothing more than an inferior little brother compared to other levels of mecha.
Six-meter-high medium-sized mechas, fifteen-meter-high advanced mechas, and one hundred and fifty-meter-high interstellar mechas were lined up in front of her, which was truly dazzling.
Su Buyan sighed and said, "I now completely understand why you hid Shao Siming's black silver mecha. It's a new type of mecha I developed, and it was originally kept secret. Because it hadn't solved the problem of defending against psychic attacks, it hadn't yet been deployed to the interstellar forces."
"But somehow the news has spread. Several other countries in the Beichen Galaxy are ready to make a move. They are said to have sent spies to the Beichen Empire to gather information on the new mecha."
Xia Chujian didn't care at all. She held her chin with both hands and looked at these conventional mechanical mechas in fascination, saying, "The Shao Siming mecha is indeed a groundbreaking breakthrough compared to these conventional mechas. But I still prefer the appearance of these conventional mechas!"
Those dark and dull metals, the huge and tall bodies, and the various heavy weapon systems that come with them, have a toughness and romance that is a blend of iron and blood.
Su Buyan looked a little strange: "...You actually like these big and clumsy mechanical systems?"
Xia Chujian said, "These mechas are indeed large, but they are not clumsy at all! Why can't my Shao Siming mecha have a form like this?"
She thought, if her Shao Siming mecha could also have such a majestic appearance, she would wake up laughing in her dreams!
Su Buyan's whole body trembled, and something seemed to flash through his mind.
He murmured, "The exotic metal black silver used in Shao Siming's mecha is different from both conventional and special metals. Its properties determine that it can provide close protection..."
Xia Chujian frowned and said, "Is it really impossible? I remember that Shao Siming's black silver armor can be stored in a small necklace because its melting point is quite peculiar. It can be melted by a certain voltage, and it can also be solidified into a solid defense by changing the voltage. Then why can't it be allowed to solidify into a larger shape when it forms a new solidified state..."
Su Buyan was shocked and eagerly grabbed Xia Chujian's hand, saying, "Say your last words again!"
Xia Chujian was puzzled, but he still repeated, "I just said, why can't we let it solidify into a larger shape when it forms a new solidified state..."
Su Buyan slapped his thigh and exclaimed in ecstasy, "That's right! Since changes in voltage can cause black silver to solidify into different shapes, we can add another instruction to the chip to allow it to solidify into a few more shapes!"
"For example, a three-meter-tall, regular mecha! That way, you don't have to hide anymore! You can just use it directly, and even if others see it, they'll just think it's a regular mecha!"
