The expression on Lu Feng's face also became solemn, and at this time, he could also think of some things that had happened recently.

A few days ago, martial law was imposed in the entire grassland city, and even the army was dispatched, setting up checkpoints at various intersections to check passers-by, patrolling at night also became more numerous, and the police often searched some public places.

Then, the news naturally spread, after all, the arrest operation on the side of the tavern is impossible to keep secret after the matter has passed, and everyone knows that the spy has reached his side and actually probed for information near a machine factory.

Then, many things suddenly became apparent, no wonder the factory wanted to issue a ban on alcohol some time ago, ostensibly because of the dirtiness of the diesel engine plant in the coal province, but in fact, because of the activities of this spy.

Drinking is wrong, they are a military factory, they have a lot of military secrets here, fortunately they didn't drink there!

At this time, I don't know how many people are afraid.

Of course, they also heard that the arrest operation was jointly carried out in several places, in the capital and in the south, and they were all very successful there.

Now, several days have passed, and the longer the time passes, the more difficult it will be to carry out the arrest operation, after all, there is such a time, people can already run far away.

The endless prairie is difficult to run away from without food, water and horses, but what if people are prepared? Maybe I'd have run away by now.

The country is still not peaceful in a few remote areas, and they have run away in various ways. Therefore, as time goes by, the opportunities to find these two people have become less and less, and everyone has relaxed their vigilance, and now, Qin Zhenhua's arrangement, is it something that comes to mind?

Everyone thought that the two spies ran away, but in fact, they didn't run away at all, but entered a machine factory!

A machine factory is too big, there are too many no-man's corners, those two people, if they hide in a machine factory, perhaps, it is really a clever move, this is the most dangerous place, but also the safest place.

No matter how strict the search is outside, the inside of this machine factory has almost not been affected in any way, and it is normal to commute to work, after all, as long as you use your brain a little, you know that the spies dare not come back, and the spies are back?

They hid, but they had to fill their stomachs, so they could only pretend to be rats and steal food everywhere?

Do they go to the cafeteria?

The canteen is empty, there is no place to hide, it is better to have this welding workshop on our own, there are obstacles everywhere, there is a lot of scrap iron over there, all kinds of machines, equipment, just find a place, you can hide.

"Master Lu, in the past few days, the craftsmanship has been thought through, right?" Qin Zhenhua asked.

Now, my own lunch has been eaten, what about the two people? Is it still on the shop floor, or has it sneaked away? After hearing Qin Zhenhua ask Zhao Ming to inform the people in the security department, those two people, if they really existed, would definitely slip away.

Unless... Unless there's something more appealing to them, what's more appealing to spies right now than technology? The other party is lurking in Prairie City, that is, to steal the intelligence of a machine factory, and now, hiding back and forth in the factory, although it looks embarrassing, in fact, there is really a lot of information.

Now, Qin Zhenhua and Lu Feng are talking about craftsmanship, perhaps, the other party will take the risk of staying and listening, during this time, they come and go freely, and it is estimated that they have found a shortcut.

Well, that's the only way left.

Lu Feng said: "I have thought it through, our new generation of tanks can start welding, we are confident, even if we do this, we can't stop, it's a little tiring." ”

"Oh, that's right, but don't worry too much, we plan to introduce automatic welding equipment in the future."

"Automatic welding equipment?" Hearing Qin Zhenhua's words, Lu Feng became excited: "Automatic welding? How can it be automatically welded? Do you want to use a computer? ”

"That's right, just like our CNC lathes, there is a computer-controlled robotic arm, and this robotic arm, holding a welding handle, can weld the weld. In this way, we welders only need to weld those places that are not easy to weld. In the West, I have already seen this type of welding. Well, this one is called a welding robot, and it's tall. ”

In the past few years, the first welding robot in the United States has appeared, and in China, since the seventies, this technology has also been studied, but, for now, it is still very difficult, and it has hardly entered the practical field.

Anyway, I'm bragging now, what can't be said, we've seen the world abroad.

Qin Zhenhua said this, Lu Feng was also interested, I don't know if he was really interested, or if he was cooperating with him in the exercise, and at this moment, suddenly, a buzzing sound sounded on the side.

It's the sound of an electric motor! Then, with a creak, the sound of the wire rope braking was heard, and the two raised their heads and looked overhead.

A machine factory is a heavy machinery factory, the operation of various devices are large, take the welding workshop as an example, all kinds of car body steel plates, often on the weight of tons, so, back and forth to carry [new www.xxbiquge.xyz], overhead crane, that is a must.

And now, above their heads, at this time, there is a crane passing by, on that crane, hanging an uncut steel plate, estimated to weigh more than twenty tons, now, it is stuck on the top of the heads of the two, and then, with a speed visible to the naked eye, the steel plate fell from above!

Nima! Qin Zhenhua suddenly cursed secretly in his heart, originally thinking that even if these two people were hiding, they would be cautious, like rats crossing the street, where would they dare to take the initiative to appear.

Who would have thought that people would actually take the initiative to attack, and at this time, they would actually attack the two of them.

In the workshop, at this time, there were only Qin Zhenhua and Lu Feng, and the operation of the crane must have been manipulated by the black hand hidden behind the scenes.

Moreover, as long as they can't be caught, then, this incident, in the end, will be regarded as an accident, the crane accidentally lost control, if the other party has a heart, you can also pour a basin of water into the control room of the crane and burn the circuit, so that the camouflage is more like.

At this moment, Qin Zhenhua thought about these things clearly, and now, in this situation, it seems that it is not easy to run out.
