With the money and goods settled, Su Ming merely stood there with his arms folded, watching Blue Beetle buzz away carrying the three items as he waited for Hal's examination results on the three hostages.
Hal had absolutely no medical background. He knew less about how many bones the human body had than a mercenary like Deathstroke did, and he still had to go to the hospital whenever he caught a cold.
But the Power Ring made up for that weakness. As long as the tiny ring had energy, it could take X-rays, perform CT scans, MRI scans, and a whole host of alien-tech diagnostic procedures.
Moreover, the Power Ring could project the injured person's condition in simple diagrams that even an idiot could understand, allowing Green Lantern to consult them.
Yes, merely consult them. Even if it found internal bleeding or severe fractures, Hal would have no idea how to treat them.
It couldn't be helped. He was in the Air Force, after all. The Air Force of the new era was no longer the profession from before World War I, where people flew biplanes and shot bricks and throwing knives at enemy pilots.
Compared to the Army, pilots generally did not get injured. If they did, the injury was fatal. Whether they were hit by aircraft cannons or had a missile warhead strike the cockpit, they would die immediately. There was no need for first aid.
"They show no signs of poisoning. Or rather, the Power Ring can't detect any." Hal looked grave, unable to understand why this was happening. "The Stranger simply passed out from exhaustion, though I have no idea what could exhaust him. As for Donna and Kara, their outer brain membranes are wrapped in a black mist-like energy, preventing me from scanning their brainwaves."
