This instrument is somewhat similar to the old eye tracker. It displays a holographic image, captures the movement trajectory of the eyes, and finally calculates their focusing speed.

Jiang Ling quickly used the machine to measure her binocular coordination score. She didn't know where her score of four nines ranked among the general population, but she should have passed.

Next is visual resolution and night vision, which are tested together.

There is also nothing much to say. Color blindness is easy to be discovered, and they usually can't even pass the initial selection stage; as for night vision ability, they seem to just check it roughly. Thanks to the development of modern nutrition, almost no one will be stuck in this item.

Afterward, Jiang Ling successfully passed the tests for hearing, touch, smell, and taste. She felt these tests were somewhat redundant. After all, 90% of human perception comes from vision, while the remaining senses are usually only used to assist in judgment. Once the eyes are deceived, the other senses will also be deceived.

"Next..."

Jiang Ling pushed open a door that looked a little different.

There are not many people in this room, and there are only a few doctors working inside. Many people are just here for formalities.

"Excuse me, what is this place for?" She pulled the person in front of her and asked.

"I don't know either. It seems like all I have to do is follow the team!"

Yeah?

The team moved forward, and when they passed a Mediterranean man in a white coat, Jiang Ling was stopped by him.

"Wait! Let me see!" He squinted his eyes and looked forward, as if he was observing some animal.

"Hey, what do you want to do?" Jiang Ling took a step back and avoided the head that was approaching.

"It's a psychic! Psychic, go that way!" He suddenly climbed onto the table and pointed his finger at the small door on the other side.

Instantly, the entire place fell silent; even the person at the front of the line, mechanically stamping their documents, stopped. The crowd gradually parted, clearing a path for Jiang Ling. Only then did she sense a faint psychic fluctuation in the room.

She opened the small door and took a few steps inside. Suddenly, more than a dozen fully armed robots appeared. They were on full alert, with more than ten guns and several instruments pointed at Jiang Ling, which frightened her greatly.

In the dim room, several flashing white lights made Jiang Ling's eyes hurt.

"Ahem, don't be nervous." A trembling voice came from a speaker in the room. "The test has begun. First, please tell me my exact location."

"Is this a recording?" Jiang Ling blocked some of the light with her arms and pressed her back against the wall.

The video recorder in the room faithfully recorded everything that happened.

Not long after, the loudspeaker continued: "Now prepare for a new round of testing, three, two, one..."

They didn't care about the thickness of the wall at all, and the muzzles of the guns were ready to fire at the same time.
