Although Su Ming and others were very curious about where Mia was taking them in the middle of the night, they didn't dare to ask more questions seeing how mysterious she was.

An hour later, Mia led them around, avoiding the patrolling security guards, and from the underground garage to the central training building of Huangting Academy.

"This way."

Mia gently led them to a door without any sign.

This door still has the original mechanical lock.

Mia took out a special metal wire from her pocket and started tinkering with the original mechanical lock on the door.

When Su Ming saw this scene, his expression was as exciting as he wanted.

Rhine and the others were even more shocked, and they all spoke in a panic.

"Teacher, what are you doing?"

"Unlock it!"

Mia replied without even thinking about it.

"Teacher, is this inappropriate?"

"You're not going to lead us as thieves, are you?"

"Teacher, why don't we go back? We don't want to be expelled from school the next day!"

Rhine and others were panicked. It was obvious that this was the controlled area of ​​the college.

"What are you afraid of? I will be the one to take care of you if anything happens."

Mia replied nonchalantly.

When Su Ming listened to Mia's words, he also felt that she was really too random. He was just about to say something.

Click!

The mechanical lock was opened by Mia.

Su Ming decisively swallowed back the unspoken words. It was too late to say anything now, the lock had already been opened.

Mia opened the door excitedly, waved to everyone and said.

"Come in!"

Su Ming and others could only bite the bullet and walk in.

The room was very dark and I couldn't see clearly at all.

But then Mia pressed the switch on the wall.

Bang~

Rows of lights came on.

Su Ming and others were stunned when they looked at the scene in front of them.

They are now in a very special training room with two closed changing rooms in the corner.

In the middle area of ​​the training room, there are rows of cylindrical pools sunk into the ground, and there is nothing else.

Su Ming and others looked at the training room in confusion.

"Teacher, what is this for?"

Ellu asked politely.

"Don't ask so many questions. There is a changing room over there with training clothes. Go and change!"

Mia carefully closed the door, and then said to Su Ming and others.

Although Su Ming and others were confused, they still walked to the changing room obediently.

Soon after, Su Ming put on a pair of shorts similar to swimming trunks and walked out with his upper body naked.

"Wow, squad leader, you actually have so many abdominal muscles! No wonder you are so strong."

Zhang Yi joked with a smile.

"Let's see how squad leader exercises. Your abdominal muscles look pretty perfect, not like dead muscles."

Shi Wushan and others came forward excitedly.

"Okay, stop making trouble! Are you in class now?"

Su Ming said with a dark look on his face.

"Don't look at the monitor. What's so interesting about that? Look at the girl in our class."

Mandy shouted excitedly.

Su Ming turned around and looked over, only to see An Qi, Ai Lu and others all put on tight-fitting training clothes. The clothes were almost attached to the skin and perfectly outlined their figures.

"Wow!"

Zhang Yi and others shouted excitedly.

Ai Lu and others all rolled their eyes at Zhang Yi and others, but they didn't say anything.

Soon everyone changed their clothes and lined up in front of Teacher Mia.

Mia glanced at everyone present and said to everyone.

"Did you see the independent training pools in front?"

"I saw it."

Rhine and others responded one after another.

"Everyone, get down and hold your breath!"

Mia simply ordered.

"Ah? Why are we practicing this, right? What's the use of lung capacity?"

An Qi and others commented in confusion.

Su Ming also felt that something was wrong. What on earth was this teacher Mia going to do?

Unfortunately, Mia was too lazy to explain, she said impatiently.

"Why are you asking so many questions? There is one training pool for each person."

Su Ming and others could only obey Mia's arrangements unconditionally, and they walked to each training pool.

The cylindrical training pool was filled with a viscous green liquid that didn't look like clear water.

"Get down!"

Mia shouted to everyone.

Su Ming took a deep breath and immediately jumped into the training pool.

thump!

Su Ming's whole body sank. The training pool was not deep, only about 2.5 meters, and the buoyancy was quite high. He could float up with a little struggle.

Seeing Su Ming take the lead in jumping, everyone gathered their courage and jumped.

Mia then took out a professional timer and pressed it.

Time passed by second by second, and when the timer reached 3 minutes and 29 seconds.

Mandy was the first to be unable to hold on, and was the first to float up, gasping for air, followed by famous students one after another.

Mia looked at the floating students and frowned.

Ordinary people can hold water for four minutes as long as they are trained. But the water in these training pools is not ordinary water, but special liquid used for NOCY training.

These training liquids themselves contain oxygen and can penetrate into the body through the skin, so they can be held in for longer.

But now it's only been more than three minutes, and I'm starting to lose it.

Mia continued to watch patiently.

As time goes by, more and more students are floating.

When the time came to six minutes and twenty seconds, Rhine emerged from the training pool, breathing heavily.

"Huh~"

"Okay, Rhine! Did you hold it in for so long?"

Zhang Yi and others praised him one after another.

"It's okay, am I the longest one?"

Rhine asked excitedly.

"Well, that's not true. The monitor hasn't come up yet?"

Zhang Yi explained to Rhine.

"Isn't it?"
