Gu Mang had told Yu Mufeng to deliver something last night.
As Gu Mang's movements were quite restricted on Jijing Island, he had only managed to bring the item over with Responsive Dragon's help.
As soon as he got off the plane, he heard the news of the Leng residence burning down. He laughed and rejoiced over their misfortune while saying that heaven indeed had eyes.
It was only when he arrived at the villa that he found out that it was Gu Si's doing and that Gu Mang's hand was seriously injured. He blew up right there and then. And I was wondering why she wanted me to bring this thing over.
Gu Mang looked toward the box. "Has it been tested?"
Yu Mufeng nodded. "This is the latest model. My dad worked on it with Red Scorpion based on your manuscript. It's currently only available at Red Scorpion's general hospital and it's more convenient to use than the previous one."
