After Old Master Fu was done talking to the two scientists from the Space Academy, he went to his usual room with a walking cane. He had suffered a lot when he was young and worked day and night after entering the Space Academy. Now that he was old, he could not walk well. Even at home, he had to rely on a walking cane.
Li Jinnian was resting with his eyes closed when he heard the sound of the sliding door. He suddenly opened his eyes and quickly stood up.
"Slow down," he said softly as he helped the old man into the house. He steadily helped his white-haired grandfather sit down. "You're old. It's better to worry less about the Space Academy. Don't waste your energy, lest your body can't take it."
