A week flew by.
Aside from the times he came out for food, Su Yutong had never seen the door in front of her open.
She gently set the pouch of Space Food outside the door, then reached out and knocked softly.
"Professor, it's lunchtime."
As usual, there was no response.
Su Yutong was hardly surprised. She shrugged and prepared to leave.
Based on her past experience "feeding" him, the food probably wouldn't be taken inside for another hour or two.
But today seemed a little different.
She had barely turned around when she heard the mechanism of the office door opening behind her.
Su Yutong froze for a moment, then instinctively turned back toward the door.
Lü Yongchang looked haggard, but his eyes shone brightly!
"P-Professor?"
Su Yutong called softly.
Perhaps her voice snapped Lü Yongchang out of his thoughts, for he abruptly stopped midstep.
"Oh, Yutong..."
Lü Yongchang glanced in her direction and said in an extremely hoarse voice, "I need to go to the Biological Laboratory."
With that, he stepped out through the doorway.
"Careful!" Su Yutong cried softly. "Professor, your lunch!"
Lü Yongchang stopped midstep again.
He looked down and finally noticed the lunch sitting outside his door.
"Lunch... Never mind, I'll eat later." Urgency and excitement flashed in Lü Yongchang's eyes. "Oh, Zero, is Mao Zhengzhi in the lab? Tell him I've figured it out!"
As he spoke, he tried to step around the pouch of food in front of him.
But he soon stopped again.
There was only one reason.
He had noticed Su Yutong glaring at him.
After a brief internal struggle, Lü Yongchang chose the path of least resistance-he silently bent down and picked up the pouch of Space Food.
"Ahem! I just realized I'm a little hungry..." A trace of embarrassment
