After all the tests were passed, it took another hour to paint the trailer and add the iron cage. During this period, the engineers changed the oil and filter element of the power generation diesel engine and the traveling mechanism of Raytheon. Liu Shubao also quickly mastered the basic structure of some chariots under the guidance of Shi Qingshan and Wang Hongwen.

At this time, he seemed to be an expert among the six members of the chariot, commanding the chariot to retreat with a clear eye, hooking up the trailer, connecting the hidden brake hose and control lines in turn, and no longer smiling hippie, quite like an old driver.

The triangular track of the trailer is a component that is prone to failure, and after President Jin instructed the trailer to install maintenance tools and vulnerable spare parts, he repeatedly introduced the precautions to Shi Qingshan and Liu Shubao, and then completed the handover.

Shi Qingshan felt the serious and dedicated spirit of the group of mature and wise or young and intelligent engineers in front of him at close range, looking at their pale temples, sweat on their heads, and their eyes were hot for no reason.

"Smack!"

He raised his head and chest, saluted a standard military salute, turned his upper body, and slowly swept his gaze over everyone.

Liu Shubao and Hu Zhenfeng also stood up and saluted, paying the highest respect to these backbones of the country.

Dean Jin was stunned, thousands of emotions suddenly welled up in his heart, tears fell, choked and stretched out his hands to shake hands with Shi Qingshan and several others one by one: "Take care all the way!" ”

"Take care!"

"Goodbye!"

The seven men got into the car and waved goodbye to the group, and the chariot started silently, quietly slid away, and drove out of the underground parking lot with the engineers' finely crafted trailer.

......

It is said that through a month's efforts, the troops occupied all the substations along the capital to the northern plateau, so that Yanjing directly used the wind power from the prairie.

Sydney's family lives in Xiyuan Park, and on the way there, Hu Zhenfeng asked Shi Qingshan: "Shi team, where is the other person in your car group?" Commander Yang asked them all to call. ”

Shi Qingshan still has a grudge against Hu Zhenfeng for killing Wu Jing. Although it may have been wise for him to do so at that time, otherwise Wu Jing might have been dragged away and the end might have been even worse, he still felt psychologically uncomfortable, because Wu Jing did not ask others to kill him at that time.

To give a simple example, it is like a comrade-in-arms who is injured on the battlefield and is in pain, but you can't see him in pain, and shoot him to death while he is still fighting with death.

No one has the right to deprive another of his life at will, except at his own request and under circumstances of his excruciating pain that cannot be saved.

Shi Qingshan pondered whether this was a woman's kindness, but quickly dispelled this idea. He has never been merciful to villains and enemies, and the reason why he is unhappy may be because of Hu Zhenfeng's approach at that time and his comrades-in-arms, "don't abandon, don't give up!" "The spirit is contradictory, right?

"Staff Officer Hu's decisive character is more suitable for surviving in the last days, right?" He thought.

"Stone team?" Hu Zhenfeng saw that Shi Qingshan didn't react, so he shouted again.

"Oh!"

Shi Qingshan came back to his senses, "Forget it!" Zhang Gong didn't go south with us, now we have to pick him up for at least half an hour, don't let Commander Yang wait for a long time! ”

"Oh...... Is that Zhang Gongjia from Yanjing? Hu Zhenfeng asked casually.

Shi Qingshan nodded silently: "Hmm! ”

Hu Zhenfeng also vaguely guessed at this time that Shi Qingshan might have an opinion that he shot Wu Jing and killed the giant rat together.

In fact, after a day of getting along, he already had a sense of sympathy for Shi Qingshan, and sincerely wanted to make him a friend, and he didn't want to be estranged.

After thinking about it again and again, he sighed and said to himself: "In this world, the heart is not ruthless, and the stand is not stable!" ”

Shi Qingshan raised his eyes and looked at Hu Zhenfeng, understanding that he was admonishing himself, but he did not agree with this sentence in his heart.

Everyone has their own way of dealing with people in society, or they are exquisite, or loyal and kind. Or scheming, or sunny and cheerful. It is difficult to say that a clever person will live better than a loyal person, and a person with more eyes will suffer less than a person who is arrogant. There are positive and negative sides to things, as long as you don't do bad things, the principles that suit you are the best.

Shi Qingshan was relieved to figure this out, the world was in chaos like this, there was no need to dwell on who was right and who was wrong, any decision might be wrong in that situation at that time.

People can't be resurrected after death, so that the people around them now live with dignity is the most important consideration! Although he is not a virgin, he is a soldier! If you can't do anything to save the world, try to take care of the people you know.

He thought for a while and said to Hu Zhenfeng: "Can I trouble you?" ”

Hu Zhenfeng's heart was relieved, and he hurriedly said: "Please speak!" ”

Shi Qingshan hesitated and said, "The Zhang Gong who didn't come is a local, and now he temporarily lives at No. 88 Longtan Villa. That house is quite eye-catching, and I'm worried that bad people will trouble him, can you help take care of him after we leave? ”

Hu Zhenfeng happily agreed: "It's a trivial matter!" I'll say hello to the person in charge over there tomorrow. ”

Shi Qingshan hurriedly thanked him.

Hu Zhenfeng can promise to take care of Zhang Gong's family, he let go of a piece of his heart, earlier he promised that the members of the car should take care of each other, no matter how chaotic the world is, not forgetting the original intention is the foundation of being a man.

The women were all looking out the window in a daze, while Liu Shubao was holding his sheep and watching Wang Hongwen control the chariot in the cockpit.

In fact, simply driving a chariot does not ask much, Anjia can get started quickly, in the case of unobstructed roads, no zombies and vehicles blocked in the middle of the road, the chariot can choose automatic driving, in case of special circumstances, it will automatically dodge, and it will send a prompt if you can't dodge, stop and change to manual driving.

The most basic aspect, first of all, Liu Shubao must learn to look at the posture of the chariot. Because Thor's driver's seat is equipped with gyroscope swing compensation and shock absorption buffer, it will always remain vertical when it is powered on, no matter whether the chariot crosses a trench or climbs a steep slope, the seat will move in the opposite direction to the chariot's tilt, and the driver will always maintain the most comfortable posture, so you don't know the external attitude of the chariot based on feeling alone, and you also need to be able to look at the attitude gauge, just like flying an airplane.

There is also a combat vehicle because it is fully electrically propulsed, so its travel mechanism is slightly different from that of the internal combustion engine. Ordinary combat vehicles mostly drive the tracks to roll through the two driving wheels outside the gearbox, and cooperate with the supporting pulleys and load-bearing wheels. The all-electric propulsion is driven by the driving wheels on the four DC motors on the front and rear sides, which is equivalent to an automatic two-wheel drive vehicle becoming a continuously variable four-wheel drive vehicle.

This is still simple, because Liu Shubao knows a lot about the mechanical part and the electric and motor, and he has the talent in that area, and he can understand it at a glance. But when it comes to digital operating systems and microelectronic circuits, he is a primary school student, and he is not even as good as Shi Qingshan.

Shi Qingshan at least learned some digital theories in college, while Liu Shubao only graduated from a technical school majoring in mechanical and electrical maintenance, and only knew a little about the basic principles of electronic circuits, so it was extremely difficult to understand.
