Just at that moment, Xu Yang and Lew Hang appeared together in the box!
He assumed Ge Zhicheng was conducting a 500-ton-class engine test, so he did not intervene.
The blueprints for Huang's 500-ton-class engine had been delivered to them two days ago.
He had specifically instructed his team of researchers to study it thoroughly!
However, Xu Yang noticed something amiss!
Having spent two days at Kyoto's rocket engine research center, Xu Yang was more than familiar with Huang's 500-ton-class engine!
He immediately spotted the numbers on the control panel!
In the fuel mix, they had added more hydrogen, clearly aiming to increase the engine's power, to boost the engine's thrust!
Xu Yang had a design for a 1000-ton-class engine in his mind, so he knew that the fuel needed for a 700-ton-class engine was vastly different from that of a 500-ton-class!
