He was swaying on his feet, after all, he was getting older. Standing like this for a whole day, coupled with mental tension, it was hard to endure despite his good physical maintenance.
Fortunately, Song Chongjin quickly caught Old Doctor Du.
He had also changed into some freshly laundered clothes and cleaned himself up before daring to come in.
After escorting Old Doctor Du to the door, he asked Yao Da to help him home, attended to his bathing, and prepared a meal, ensuring he ate well before taking a good rest.
Turning around, he looked at Wang Yongzhu's disheveled appearance, feeling quite heartbroken: "I'll stand guard for you. If there's anything I need to watch out for, let me know. You should go freshen up, eat something. You've gone a whole day without eating!"
Earlier, Wang Yongzhu had already seized the moment when Old Doctor Du wasn't looking to feed a drop of the Level C Gene Nutrient Solution from Chen Xing to Old Man Wu, knowing he was fine at the moment.
