The better the drive unit performed, the greater the power and speed behind each punch, and the more destructive force it could unleash!
If they wanted to increase the suit's power, the drive unit was one of the most crucial components!
If the Iron Man suit had been strong enough back then, when the Fire Dragon bit down on it, he could have pried its jaws apart directly, escaped with ease, and even pulled out every last one of its teeth!
So Tony Stark's first priority was to develop a more powerful new drive unit!
Chen Mo had nothing much to do at the moment. The Fire Dragon's modifications would still take some time, and there was no telling how long it would take to perfect the Extremis Virus. Since he was idle anyway, Chen Mo simply joined their research!
Upgrading the drive unit sounded simple enough. After all, it was only a basic power component, far less complex than the Iron Man suit's overall structure. But precisely because its structure was simple, improving its performance was actually difficult!
If Tony Stark wanted to increase the Iron Man suit's strength, he could simply use twice as many drive units. If he wanted to increase its flight speed, he could add more thrusters. The suit might become bulkier, but its combat power would certainly improve!
In fact, this was the simplest way to enhance the Iron Man suit!
But Tony Stark clearly would not allow a super genius like himself to take such a low-effort shortcut!
And the drive unit itself obviously could not be strengthened merely by increasing its size. That would only push the Iron Man suit toward becoming larger and larger!
What Tony Stark wanted was a fundamental technological upgrade that would increase the drive unit's power output
