"Click, click..."Chen Chen stretched his waist comfortably.

One day and one night, he slept comfortably and practiced for most of the day, and when he woke up, it was already dark.

He took some food from the ring and quickly filled his stomach, and when he had finished eating, he took out the guns and grenades, loaded them with bullets, put them away in sorts, and went to the entrance of the dugout in the darkness of the night.

When he was about to get off the highway, he put the car away, and then started to work lightly, and made a few vertical leaps to the bomb shelter.

He moved the big stone away, and when his body entered, he blocked the stone back untouched.

It's pitch black inside, you can't see your fingers, and there's not a trace of light!

This kind of absolute darkness can make people's hearts fearful, but fortunately it does not include Chen Chen.

Because he knows that there are no ghosts in this world...

took out an absenteeism hat from the storage ring, pressed the headlamp on the absenteeism hat, and the air-raid shelter was instantly illuminated.

When he came to the iron gate, it was indeed as he saw during the day yesterday, the iron gate made of steel bars was very strong, and each steel bar was the thickness of a baby's arm!

The place embedded in the wall next to it seems to be connected to the steel bars of the bomb shelter, and it is believed that the cement was chiseled first, then welded, and finally re-plastered with cement during construction.

The big lock was not ordinary, and the steel bars next to it were rusty, but the big lock was only stained with some dust.

Chen Chen weighed it with his hands, at least more than 20 catties!

He took out the equipment of acetylene flame and asked the system in his heart: "System, what should you do if you encounter this situation?" ”

System: "Don't talk to the system during the mission, this is the final test for the host." ”

Chen Chen pursed his lips, the flamethrower in his hand made a clattering sound, adjusted the size of the flame, and then began to cut around the lock.

"Let's just chat, not from your set of information." Chen Chen also took the time to light a cigarette.

He is also trying to calm himself down, otherwise he will be too nervous and easily affect his judgment.

The system was silent for a moment before saying: "It's still that the host's courage and cultivation are not up to par, the host can get a plane, and then jump off without a parachute near Fort Rick!"

If you have the internal force to slow down, and you can't fall to death, you can jump directly into the enemy's lair. Also, the lock in front of you is also very easy to open, put the mental power into the keyhole, and with a little effort, you can directly open the lock, why is it so troublesome! ”

Chen Chen: "......"

A bit autistic.

Don't want to talk anymore...

It's the same people, why is the system so good?

The system continued: "You are in the modern age, and it is right to use modern thinking for everything, but it is better to incorporate what you have learned into it so that it can be most effective." ”

Chen Chen nodded teachablely, the system is all based on experience, and the first thing to consider when encountering something is the most labor-saving and direct way.

He didn't think about it.

He didn't even think about jumping from a high altitude, and the system looked like it was normal.

It seems that the way of thinking about problems in the future should be as far as possible from the perspective of mortals.

In fact, it's not his fault, living in the city, where would he think about those strange things that go against human common sense.

……

The acetylene flame cut quickly, and in less than twenty minutes, he harvested a large steel lock and opened the iron door smoothly.

Without any further delay, Chen Chen walked lightly and quickly towards the depths of the air-raid shelter.

Being in an air-raid shelter, it is easy for ordinary people to lose their way, unable to distinguish between southeast and northwest, and even if they go around the road, they may not be able to find the way they came!

Fortunately, Chen Chen is a cultivator, and his sense of direction is still quite keen, and after walking a fork in the road, he chose the right direction to Fort Rick without hesitation.

What does it feel like to run alone in a bomb shelter at night?

I believe that few people can experience it firsthand.

I could hear my own breath, my own footsteps, and the slightest echo, but nothing else!

Chen Chen regretted it a little, he knew that there would be today, he would have collected a motorcycle into the storage ring, and he could get there with a few feet of throttle, and he still struggled to run with his feet.

It's not impossible to drive, the bomb shelter is very spacious, about two meters apart, but if you encounter a turn or something, the car will not work.

Of course, it would be better if there was a system of electric vehicles in that time and space, and Chen Chen's world does not seem to have popularized electric vehicles on a large scale.

Hey?

Chen Chen, who was running, seemed to have found another way to make money...

It's doable to think about it!

Electric vehicles are simple in structure, battery technology is available in Huali, and it is also very advanced.

It is estimated that after a year and a half of research and development, the finished product can be made, and then while the market is not yet popular, build a brand first and occupy the market in advance!

The memory of the later stage of the system is that new energy vehicles such as electric vehicles are gradually replacing gasoline vehicles, but it is estimated that it is not easy.

After all, there has been no breakthrough in battery technology, and an electric car is actually just a machine that sits on a battery.

Chen Chen thinks that hydrogen energy vehicles are good, which can replace gasoline and will not pollute the environment, but the energy conversion link in the middle needs to be broken through.

When the separated hydrogen is equivalent to the value of the same amount of gasoline, then hydrogen energy will dominate the market!

After all, there is no pollution, and any city will welcome it.

Secretly keep this idea in mind, and in the future, it is completely possible to let your car company develop in this direction.

"The Point Guard Is Here"

Now, let's digest the technology given by Lisa first.

I don't know how far it can develop, it's better than nothing, and besides, he doesn't have ready-made engine technology, or he is just lagging behind...

If he digests what Lisa gave, he believes that even if he can't catch up with the world's top level engine, it shouldn't be much behind...

In fact, Chen Chen didn't know that the engine technology that Lisa gave him in Ri Province was even more complete than he imagined!

Of course, it's one thing to know how to make it, and it's another thing to make it...

You must know that a lot of awesome technologies, even if they don't rely on patent protection, they just can't make it according to the model!

This distress entangled TT experts for two years before it was finally solved...

Of course, that's all for later.

Car building is another major part of Chen Chen's company, and these technologies have accumulated enough, so that he can touch the aerospace sector.

There is a need not only for technology and talent, but also for ... Money!

When the time comes, rockets and spaceships will be built, and they will have to go through countless tests, and it will be a great loss to blow up one of them!

……

After running at a high speed for more than half an hour, Chen Chen stopped, not to reach his destination, but to encounter an iron gate again...

And after seeing this iron door, Chen Chen suddenly wanted to scold his mother angrily...
