Half past two in the morning.
Song He woke up, threw off the covers, and sat down in front of the computer.
More than a dozen mathematics papers were open on the computer at once. Although Song He had scored 140 on his English exam, he still had many blind spots when reading English papers and had no choice but to rely on translation software.

His head hurt terribly. His brain felt like it was about to explode!
Mathematics Progress detected. Promoted from Gold Level 67 to Gold Level 68! Mathematics Progress detected. Promoted from Gold Level 68 to Gold Level 69!
The dizzying feeling of oxygen deprivation struck again. Song He rubbed his temples in pain.
A moment later, he suddenly slapped his thigh.
Since he so often became oxygen-deprived while solving problems, why not buy some oxygen?!
He took out his phone and searched for canned oxygen. To his surprise, the delivery app could deliver it. A twenty-four-hour pharmacy sold one-liter cans of oxygen, so he decisively ordered a whole case of thirty-six bottles!

The deliveryman came wobbling along on an electric scooter. Song He waved to him.
