Light Castle, Main Building One, fifteenth underground level, furnace maintenance room.
Richard, Lorenz, Schrodinger, and the other stewards entered. Several supervisors from the maintenance room immediately came forward to greet them.
Siemens, the golden-haired steward, got straight to the point. "Lord Richard, all furnace indicators are normal. As long as nothing unexpected happens, it can operate for a long time. You have nothing to worry about."
Richard nodded lightly after hearing this and walked toward the deepest part of the maintenance room. Through the glass wall, he could clearly see the furnace in operation.
The so-called furnace was an enormous, flattened tank-shaped device. Its size was rather exaggerated, standing twelve meters tall with a diameter of twenty meters.
At that moment, the furnace resembled a kettle filled with boiling water. "Gurgle, gurgle" sounds continuously came from within, making the entire furnace tremble slowly and causing even the maintenance room itself to shake slightly. During this process, an immense amount of energy surged out of the furnace and was transmitted through the dense lines laid beneath the floor into Light Castle's energy trunk line, where it served its purpose.
Richard studied the furnace seriously for quite a while and could not help sighing inwardly: It hadn't been easy.
It really hadn't been easy.
This furnace was the physical form of the so-called "Sun in a Bottle," and the principle involved was the once-unattainable controlled nuclear fusion.
Yes, controlled nuclear fusion.
Nuclear fusion was comparatively simple to explain. It was exactly the opposite of nuclear fission—nuclear fission split a heavier atomic nucleus into two or more lighter atomic nuclei, with the lost mass converted into energy during the process, displaying terrifying power. Nuclear fusion, on the other hand, combined lighter atomic nuclei into heavier atomic nuclei under certain conditions, with the excess
