Zhang Gangchuan received a reply from his superiors, knowing that the prototype would be transported to the Power Engineering Laboratory. He regretted submitting the report and thought it was 'equivalent to losing a prototype'.
In fact, he was not prepared to lose the prototype. He just thought that sending the prototype over for Zhao Yi to take a close look, study it, and review the accompanying materials would be enough.
The Power Engineering Laboratory did not have adequate facilities to make the engine run, and since it couldn't even be turned on, it was impossible to conduct any other research.
So before Yuan Haitao and his team arrived, Zhang Gangchuan said he would 'cooperate with all tasks', but he only planned to have them come over for a short time, expecting them to return in a few weeks.
Yuan Haitao was the team leader and one of the high-end technical personnel in the R&D group.
He cared about the prototype even more than Zhang Gangchuan did.
