"Knock, knock!" Someone knocked on the bedroom door.
Song He got up and opened the door, but there was no one outside. Two cardboard boxes, one large and one small, sat by the entrance. They contained an oxygen generator.
The large box held a common household oxygen generator with a five-liter capacity, enough to meet the needs of his brain cells burning fiercely.
The small box held a compact mask-style oxygen generator. It looked much like a gas mask, so he could wear it to class tomorrow.
Song He plugged in the large oxygen generator and studied while breathing in oxygen.
During the day's classes, Yu Anbang's scheduled lessons had reached page 85, while Song He had raced all the way to page 200. But it still wasn't fast enough. If he wanted to stand out in the class, he had to stay up all night and catch up!
Night had fallen heavily outside the window. The Dormitory Building was brightly lit, and the boy sat upright as profound and complicated knowledge flashed before his eyes.
Thermogravimetric Analysis, calorimetry, Gas Volumetry, Fast Pyrolysis...
Differential Thermal Analysis, Differential Scanning Calorimetry, Microcalorimetry...
Heat Flux, Heat Flow, heat enthalpy, entropy, Kinetic Phenomenological Law...
Upgrade notifications kept popping up before his eyes. Besides chemistry upgrades, a few physics and mathematics upgrade notifications appeared from time to time.
Song He sighed. The sciences really were closely interconnected. Even something seemingly as simple and crude as explosives required knowledge of physics, chemistry, and mathematics. Add biology, and the set would be complete.
He suddenly froze, his mind filling with wild possibilities.
Could explosives be connected to biology?
The thought was like a spark emerging from a wasteland. At first, it was only a faint glimmer, but soon the flames spread in every direction, completely beyond control!
