Chapter 486: Zhang Gangchuan Must Work Hard!_3

Kunlun engines haven't even reached this stage yet!

Moreover, using the J-20 for testing, if the J-20 can be adapted, what's the point of developing the Warhawk II engine?

Zhang Gangchuan's mind was in chaos, he didn't even know how he left.

Liu Jiankun, on the other hand, sat back in his lounge chair with a relaxed mindset, sipping tea. He thought that telling Zhang Gangchuan about it was a great way to "shift emotions."

Just now, it was he who was shocked and bitter-smiling.

Now he could calmly drink his tea as if he didn't care about anything, and it was Zhang Gangchuan who became shocked and bitter-smiling.

"This is really a good method!"

Liu Jiankun's mood lightened, and his mind became much more agile. He suddenly thought of the Warhawk II engine and immediately had a great idea, "The Warhawk-1's technology is high-end and its performance superior, but its cost is still a bit too high."
