The No. 4 underground training ground, a conventional secrecy level area, is located in the southeast of the first area, covering an area of about 10,000 square meters, with perfect infrastructure and complete equipment, which is used for the daily training needs of many troops in the surrounding area, and is the closest to the residential area of Zhou Hai and other pilots participating in the training, which is one of the active areas.

"It's nice to have money." After arriving at the No. 4 underground training ground, Su Peng, who had a ruddy complexion, encompassed the entire training ground in his eyes, and the whole person ran while watching, sighing slightly.

Zhou Hai heard Su Peng's exclamation, shook his head with a smile, and quietly watched the huge training ground.

Laughing and laughing, he agreed very much with Su Peng's words.

Look at this No. 4 training ground, which is visually eight meters high, about 120 meters long, and about 75 meters wide, with an area of 9,000 square meters and a total volume of 72,000 cubic meters.

Not to mention the various training equipment in the training ground, this seemingly ordinary training ground alone is enough to break through the sky.

Expensive!

It's more expensive than you think!

God knows how much money was spent on the construction of this No. 4 training ground, and then think about the No. 3, No. 2, and No. 1 in front, and maybe the No. 5, No. 6, and No. 7 in the back, as well as the entire Qingcheng nuclear submarine base.

In Training Ground 4, the top lighting system is in working condition, releasing a steady stream of soft light like flowing water, illuminating the entire area.

On the runway, several officers and soldiers belonging to the nearby area were already organizing daily physical training, and the sound of uniform footsteps and rhythmic slogans echoed in the huge training ground.

"All of them, set aside! Remind two points, first, everyone should be quiet, do not speak, do not communicate with non-participating members, and pay attention to confidentiality. ”

At this time, Senior Colonel Zhang Wu, who was at the front of the team, gave the order, and reminded everyone who stopped advancing and kept in line: "Second, during physical training, whoever has physical discomfort or symptoms, you must tell me immediately, treat it, don't be reckless, because this is 450 meters deep underground!" ”

The voice was solemn and serious.

For all participants, confidentiality and security, whether the former or the latter, are of exactly the same importance.

Confidentiality, needless to say.

As a member of the training with a high level of confidentiality, it is strictly forbidden to exchange information with non-participants in life or daily training to avoid leaking secrets.

Safety, the core of temporary training, as the training site of the Qingcheng nuclear submarine base, needs to ensure the safety of every pilot participating in the training.

You must know that the underground environment is different from the surface environment, due to changes in air pressure, light and objective environmental conditions, during the training process, the body of the pilots participating in the training will be affected to varying degrees, and then there will be corresponding physiological reactions, some people will have increased blood pressure, some people will have difficulty breathing, some people will be dizzy, and some people will even have life-threatening conditions.

If you don't find out about the situation in time, then congratulations, you have won a ticket for a lifetime tour of the underworld, a refined blue and white porcelain columbarium, plus the title of martyr and a pension.

This is not alarmism, much less a joke, but a real situation.

The threat of death, for military personnel, is never far away, even if it is peacetime.

Serious, focused, pragmatic!

Aviation industry, born from rigor, loyal to harsh, not a trace of mistakes!

At this moment, in the specially set up medical room at the entrance of the playground, there are already four military doctors and two nurses on standby, ready to rescue at any time.

Hearing the reminder given by Colonel Zhang Wu, everyone looked serious and nodded one after another, knowing the meaning of these words.

"All of them, run and go! One, two, one! ”

Glancing at everyone, Senior Colonel Zhang Wu did not continue to delay, and gave the command again, leading the entire team to run forward and merge into the training ground track.

"One-two-one!" The crowd shouted.

Colonel Zhang Wu straightened his back, his breath was slightly heavy, and he naturally found the proper running rhythm, and then shouted: "One, two, three, four!" ”

"One, two, three, four!"

The neat shouts that belonged to the team of participants in the training came out and poured around.

"All of them have, running a song - "Unity is Strength", ready, up!" After running more than 100 meters, Senior Colonel Zhang Wu's snort was a little short, he was nearly 50 years old, which made his physical fitness and function decline slightly, and the whole person looked a little out of breath, took a deep breath, his eyes were sharp, and he gave orders in a loud voice.

Zhou Hai glanced at Zhang Wu, who was a little panting, and then looked at the people around him with normal faces, did not speak, sorted out the lyrics, adjusted them slightly, and then sang loudly:

"Unity is strength, unity is strength, this strength is iron, this strength is steel, harder than iron......"

At the same time, the whole team did not stop at all, and the loud and emotional legendary song suddenly sounded, and swept away like a rolling torrent.

Sing and run, keep your feet on the ground, and work hard to move forward.

This is a legendary song, but also a legendary song, originated in 1943, the number of times sung is immeasurable, condensing the military soul belonging to China.

The soul of the army is also among the loudest notes!

There is no distinction between military branches, no system, but it belongs exclusively to Chinese soldiers!

In the training ground, accompanied by the most familiar songs, the team of carrier-based aircraft pilots who participated in the training for the first time echoed with the surrounding teams of soldiers who were training on a daily basis, and played a training symphony unique to the early morning with slightly different but emotional notes.

Time passes slowly.

It didn't take long for more and more training teams to enter the No. 4 training ground, and the runway was full of blue and white sea soul shirts, all of which were military personnel and naval soldiers from various departments stationed in the surrounding area.

"Eh, big guy, take a look at the square team running towards us, in front of it is led by Colonel Zhang, there are only twelve people."

Not far away, the squadron belonging to the 'Jinling' submarine ran into the training ground, in the team, a young crew with a slightly thin face, habitually observing the internal situation, when he found the oncoming training team of only 12 people, he was stunned for a moment, his eyes lit up, and a sense of curiosity welled up in his heart, and he whispered to his comrades around.

The surrounding nearly 100 officers and soldiers are all subordinate to the 'Jinling' Type 093 attack nuclear submarine combat establishment and are stationed in the No. 1 underground area of the base.

"It seems like the pilots who are coming to our boat."

A dark-faced and rude crew member next to him looked at the oncoming Senior Colonel Zhang Wu and the ship's flight team, observed it, and said slowly.

"It's not like, it's supposed to be. Sure enough, it's flying in the sky, and the temperament is different. Another crew member in his thirties took over the conversation, looked at the closer and closer ship flight team, his eyes showed a hint of envy, and sighed slightly.
