At one o'clock in the afternoon, all the training soldiers gathered in the square of District 3, which made the originally open and empty square seem particularly crowded.

Even the trainers who are not qualified to carry engines are here at this moment.

Everyone wants to see what a carrier engine looks like.

But they were doomed to disappointment.

For at one end of the square, fifty gates were raised.

The main gate appears to be the entrance to the elevator and is supposed to be an underground area.

The underground of Cainiao Island is definitely not simple, Ling An had already guessed this, but he had never really entered the underground area.

When the electronic sign on the gate lights up with the number of a Trainer, the Trainer's bracelet will also indicate it, and the Trainer will enter the gate and go underground via the elevator.

Where the engine is carried, underground.

The sign on one of the gates changed again, and Huaji's bracelet sounded.

"Second brother, I'll go first, bless me, let me successfully carry the engine!"

"Dead boy, I'm not dead yet, how can I bless you!" Ling An scolded with a smile.

Although Hua Ji graduated from the training army as a commander, in front of Ling An, he was always the same as at the beginning, which made Ling An feel familiar and reassured.

Some things change, but some don't.

The door closed, and Huaji disappeared.

According to the previous pattern, these gates would open about every five minutes.

At this rate, even with fifty gates, it would be impossible for tens of thousands of training soldiers to carry engines in one afternoon.

Maybe some people are not here today, but just want to take a look in advance.

Soon, Ling An's bracelet also sounded.

He looked, it was Gate Seven.

Beside him, Ye Zixu's bracelet also sounded, it was the fifth door.

"002, it looks like we're together again." Ye Zixu was helpless.

The people above always seem to like to put the two of them together.

"Let's compare it, doesn't it mean that the carrying engine itself can also be regarded as an assessment?" Ling An smiled.

Without delay, they went straight to their respective doors.

Brush –

The door closed, and Ling An felt the elevator go down quickly.

He didn't know how many meters he had descended, but when the door opened again, he saw a very different place from the ground.

On Cainiao Island, except for various training grounds and accommodation facilities, the rest was very close to the original environment, but at this time, Ling An saw a pure white room.

The whole room is made of some kind of metal.

Stepping out of the elevator, Ling An looked at the room curiously.

Behind you, the elevator doors close. Ling An seemed to be completely trapped in it.

His eyes flashed, this can't be a test, right?

However, it turned out that Ling An was thinking too much, and this was just a waiting area for the people above.

A tall woman wearing a white mask and a research gown appears in the room.

"Ladybug 002, come with me."

Ling Anxin was puzzled, but he still followed the woman all the way.

The complexity of the underground surprised Ling An, every few tens of meters out there would be a door, the woman in the research uniform could only enter after swiping the card, and the door was often a fork in the road, if there was no person familiar with this place to lead the way, it was easy to get lost.

Why is this designed? Is it protecting something?

Although there were many forks in the road, under the leadership of the woman, Ling An still reached the place within five minutes.

In front of another white gate, at this moment, the indicator light on the door is red,

"When the lights turn green, you can go in." After the woman finished speaking, she turned and left in the other direction, and she had to go to pick up the others.

It seems that the elevator above is just sending people down, and it takes five minutes just to reach the place.

The reason for the control of a wave of people every five minutes may simply be that the roads here are too complicated to be carried around, and the number of staff is limited.

After waiting for a while, the indicator light turned from red to green, and Ling An pushed the door in.

Behind the door, five people in research coats were busy in front of several machines, and Ling An saw a staff member insert a metal container the thickness of an adult's arm and thirty centimeters long into an instrument.

The instrument is five meters tall and is a cylinder, with many tubes connected to it.

"Confirm the target status again."

"In good condition."

"Start injecting."

The staff's expression was as usual, and the tall woman in front of the console, wearing a white mask and long chestnut-colored hair, gave the order to inject in.

Inject?

Ling An's heart moved, but immediately a staff member shouted to him:

"Ladybug 002, huh?"

"Yes!" Ling An hurriedly replied.

"Hmm...... Go over there first and take off your clothes. The staff said.

Undressing?

Ling An was stunned.

"Hurry up, do you want me to drag it for you? Is that how you drag your feet in training? The male staff member said impatiently.

Taking a light breath, Ling An walked over to where he was pointing and began to undress.

"Take it all off, and take off your underwear." Said the staff.

In the process of undressing, several staff members over there were constantly performing some operations on the instrument.

Ling An had just finished taking it off, and the instrument in front of him was turned on. An equally naked man stared at him.

The two looked at each other awkwardly, not knowing what to do.

"Front, your clothes are in the back, go put them on yourself, and go out through the door over there." The cold voice of the staff came.

Ling An embarrassedly gave way to the brother.

It's also too embarrassing, what if it comes out is a female trainer.

Well, no, it doesn't seem like men and women enter through an elevator at all.

"Ladybug 002, go in and fix your body." The staff shouted.

Ling An hurriedly walked into the instrument.

There was a place to put his hands and feet inside the instrument, and as soon as Ling An put his limbs in, the door of the instrument was closed.

Immediately, Ling An felt that his hands and feet were fixed.

Without a struggle, Ling An knew that this was definitely going to carry the engine.

Outside the instrument, unlike the coldness that Ling An had seen before, these staff members instantly became extremely excited.

It's a far cry from when the previous trainers were loaded into the engine.

"Let's get started." The chestnut-haired woman took a deep breath.

She was none other than Dr. Qiu Yu, and at this moment, she was staring intently at the screen, on which were Ling An's various indices and his real-time images inside the instrument.

A few people around suddenly became busy.

"Detect the physical condition of the subject."

"Cardiorespiratory index is normal."

"The blood is normal."

"Inject a palliative." Dr. Qiu Yu said.

……

Ling An felt a needle in the veins of his arm, and something was injected into it.

Some kind of liquid, and the amount is not small, which makes Ling An a little uncomfortable.

Immediately, he shuddered.

Electric shock!

The voltage was not large, but it lasted for about thirty seconds, and Ling An could still endure this feeling of paralysis and pain.

He felt that the swelling in his body caused by the fluid injection had subsided a lot.

……

"The moderator has spread." The impatient male staff member from before stared at the screen and said.

Dr. Qiu Yu took out a box, and if Ling An saw it, he would definitely be able to recognize that this box was what Instructor Xiang Yi had been carrying during the previous escort mission.

Opening the box, Qiu Yu took out the contents of the box, which was the kind of metal container that Ling An had seen before.

It's just that the logo on the previous container is two crossed swords, and on this container, in addition to the crossed sword, there is also a letter G.

Dr. Qiu Yu was calm on the surface, but there was excitement in his eyes that could not be hidden.

She placed the container in the port and took a deep breath.

"Start injecting into the engine cells!"

……

As soon as the swelling in Ling An's body subsided a little, he felt something injected into his veins again.

This time, it feels like the volume is more.

I won't have to be shocked again.

Ling An muttered in his heart.

Outside the instrument, Dr. Qiu Yu stood behind a staff member, staring intently at the screen.

"Start correcting the engine cell position!"

Ling An didn't know that in order to install the engine for him, the next trainer had already waited outside the door for longer than him.

With the manipulation of the staff outside, Ling An felt his body itch.

It's not itchy on the outside, it's itchy all over the body.

This itch made him want to reach out and scratch it.

However, his limbs were fixed, which made Ling Anxin even more upset.

At this moment, Ling An would rather be electrocuted.

This itch is more unbearable than scraping it with a knife.

Taking a deep breath, Ling An told himself, hold back, hold on.

This must be carrying the engine, and what has just been injected should be the engine.

He originally thought that the engine might be something installed in the body, it must be a big chunk, maybe similar to some modders in the superhero movies of the last century, but he didn't expect it to be an injection.

Outside the instrument.

Dr. Qiu Yu looked at Ling An on the screen, although his expression was uncomfortable, but he didn't shake around, and couldn't help but nod.

"All the engine cells are in place."

"Inject a mist G substance."

"Begin to polymerize G matter, activate the engine."

Several of the tubes connected to the instrument began to shake slightly.

As soon as Ling An's itching ended, he felt another change in his body.

And what is it this time?

I thought I was going to suffer again, but this time it wasn't a change like an electric shock or a sharp itch.

On the contrary, Ling An felt that some kind of gas appeared in the instrument, and his body immediately absorbed these mist as if he had been hungry and thirsty for a long time.

Moreover, it is not only through the mouth and nose, but also on every pore of the whole body that seems to be absorbing.

The speed of absorption was very fast, and in just over ten seconds, Ling An felt that the injected gas had been absorbed by himself.

"Activate the engine control system."

Outside the instrument, Qiu Yu gave instructions.

Ling An was thinking about what these gases were, when suddenly there was a dizziness in his brain.

After a moment, Ling An was shocked to feel the change in his body.

He could feel almost every inch of flesh and blood in his body, countless small dots with shimmering light walking all over his body, and there were at least a dozen small dots of glimmer in every cubic centimeter of flesh and bones.

And between these dots, there are some thin silk threads, which connect the small dots of light all over the body.

Especially in Ling An's heart, there were nearly fifty small dots in an average cubic meter of flesh and blood.

In addition to this, there is also the location of the dantian, where a large number of small spots of shimmering light are gathered.

The silk thread seems to connect the heart from the dantian, through the spine, and finally to your own brain!

At this time, Ling An discovered that the small spots of light near the brain were almost as many as the heart and dantian!

But it all seems to be only on the periphery of the brain.

These pictures seemed to be generated directly in Ling An's mind by these small spots of light near his brain.

Ling An understood.

These tiny dots and threads that run through the whole body are the engine!
