Els's surgery, much like the one Lin Jie performed at that mysterious military base, required operation within an extremely narrow window.
First, he needed to extract Els's right eyeball from its socket.
Then, using real-time 3D angiographic images near Els's right optic nerve and the brain's visual center, he had to ascertain the position and insert a hair-thin hollow fiber tube along the optic nerve into his brain.
This process required both precision and speed.
The contrast agent injected into Els's intracranial vessel wouldn't last long, as it would be quickly flushed out by the blood flow.
If too much contrast agent were continuously injected, it could seriously strain the liver and kidneys, causing adverse effects.
Lin Jie steadied his breathing and heartbeat, picking up a hollow fiber tube with his fingers.
