"Wow, look at what you've done on the launcher... It was completely different from the one I've shown you. What about telling me what changes you've done on it so far?" Zhang Qin Feng praised Victor for his acute sense in weapon design and improvement.
At first, he felt a little guilty for showing Victor and Marvin the video clip for an older generation rocket launcher. Considering the age of the video, it was at least more than three years old. Added with the video clip was just an improved advertisement to attract more overseas buyers; the actual age of the weapon was at least five years and above.
He chooses to make it work with an older generation rocket launcher to reduce the burden for Victor and Marvin because it was their first project together.
