The next morning, Luo Yingxue gently stroked Yu Kai's head, her eyes filled with love and reluctance, a gaze that seemed to melt all the ice in the world. "Mom will be back in a few days! Shihan and Wu Xiaohu will stay with you for the next few days!"
Yu Kai frowned slightly, his eyes filled with reluctance and worry, like stars obscured by dark clouds. "Mom, I don't need anyone to accompany me. It's safe here! Bring them all with you. They can help you."
"Don't worry! A small country like Liang doesn't need them yet! Mom is leaving, you must listen to Academician Chao and never touch things that you shouldn't touch, to avoid danger!" Luo Yingxue warned seriously, her tone full of concern and majesty.
"Yeah!" Yu Kai nodded obediently, watching Luo Yingxue turn around and steadily get on a dark green military vehicle. "Mom! You must be careful!" His voice trembled slightly.
The car window slowly rolled down. Luo Yingxue smiled and waved, giving an OK sign. Then, the massive iron gate closed with a dull thud, and the car slowly ascended until it disappeared from Yu Kai's sight. Yu Kai and the others were left standing there, their eyes filled with worry.
"Xiao Kai! Let's go, your mother will be back soon!" Academician Chao Tian said softly to Yu Kai, his voice as gentle as the spring breeze blowing across the lake.
"Hmm!" Yu Kai immediately cleared up his frustration, as if locking all the gloom away in the corner of his heart. "Master Chao, do you have any mechas that require someone to enter and pilot them?" His eyes shone with curiosity and anticipation, a glimmer like the breaking light of dawn.
"This is still under research. It is a huge challenge for us to make the mecha as flexible as a human and have explosive combat power! The requirements for the driver are also relatively high. We only have the corresponding drawings now, and there are still many difficulties to be overcome!" Academician Chao Tian explained to Yu Kai as he walked, his steps slightly heavy, as if every step carried the heavy burden of scientific research.
"What difficulties have you encountered?" Yu Kai looked at Mr. Chao and asked carefully, his eyes following Mr. Chao's figure closely, his focused expression as if he wanted to engrave every word Mr. Chao said in his heart.
"This kind of large-scale combat equipment requires enormous energy to drive its complex mechanical structure, powerful weapon system, and possible flight devices. Current energy supply methods, such as chemical batteries, can hardly meet the needs of long-term, high-power operation." Mr. Chao frowned and said solemnly, his furrowed brows like a series of ravines that were difficult to cross.
"Also, in order for the mecha to be able to fight continuously, it is necessary to develop energy equipment with extremely high energy storage density. For example, if traditional lithium-ion batteries are used, their energy density is far from enough to support the mecha's long-term high-intensity activities. Although nuclear fusion energy has huge energy, it is currently difficult to miniaturize it for use in mechas." He sighed helplessly, and that sigh seemed to be a helpless sigh about the bottleneck of science and technology.
Yu Kai wrote down everything, unconsciously tightening his grip on the pen. "Anything else?"
Seeing Yu Kai so earnest, Elder Chao smiled with satisfaction, a flicker of approval in his eyes. "Also, during combat and high-mobility maneuvers, the mecha's outer shell and internal structure are subjected to tremendous stress. This requires the development of extremely strong materials that can both withstand enemy attacks and withstand the forces generated by its own movement, such as the impact of high-speed running, jumping, and flying."
"At the same time, the material cannot be too heavy, otherwise it will seriously affect the maneuverability and energy consumption of the mecha. Finding a material that is both light and strong, like the special alloys or new composite materials in science fiction works that can take into account both protective performance and lightness, is a major challenge." Mr. Chao's eyes became profound, as if he was thinking about those material problems that have not yet been solved.
"In addition, mechas need to perform a variety of complex movements, such as precise hand manipulation, flexible limb movements, and stable flight attitude control. This requires the control system to accurately convey the pilot's intentions, and the feedback mechanism to be sensitive enough to enable the mecha to respond quickly and accurately.
To better cope with the complex and ever-changing battlefield conditions, mechas require highly intelligent assistance systems. This system must help the pilot analyze battlefield conditions, predict enemy movements, and automatically adjust the mecha's state, yet it shouldn't be so complex as to interfere with the pilot's decision-making. Elder Chao spoke eloquently, as if recounting a grand yet arduous technological blueprint. His passionate words seemed to outline the majestic presence of the mecha of the future.
"Also, to make a mecha powerful in combat, it needs a strong power source to drive its rapid movement and use heavy weapons. However, too much power can make the mecha difficult to control, causing problems when starting, stopping, and turning.
While ensuring power, the mecha must also be able to flexibly operate in a variety of terrains and spatial environments, such as narrow city streets, rugged mountain terrain, and the complex environment of space. Achieving the perfect balance between power and maneuverability is a key challenge. "Mr. Chao explained earnestly, his serious expression seeming to convey the hardships of scientific and technological exploration," he said.
"Mr. Chao, can you build the mecha first? I know a power that may be able to solve these problems!" Yu Kai thought for a moment, his eyes suddenly lit up, and he said seriously, his bright eyes like fireworks suddenly blooming in the night sky.
"What power?" All the scientific researchers in the car seemed to have their sensitive nerves touched. They instantly turned their eyes to him, their eyes full of curiosity and confusion. Those gazes were like blazing lasers.
"My mother used...psychic power!" Yu Kai said seriously, his tone firm and with a hint of pride.
