Where is the helicopter? Although it is true that it is most convenient to go up and down, in addition to helicopters, there are not rockets up and down?

The sealing is done, the coating is done, the material is changed to the right, and then a fairing is made...... Can it be a rocket at all.

The rocket acceleration is nothing more than 2 to 3g.

Although the non-working fluid engine can't do it, it is a bit difficult to add a load to 1g. Even if it doesn't, it can fall into space at a speed slightly lower than that of a free-fall, and the faster it flies, the more efficient it becomes—

The most important thing in space is to offset your own weight.

The rocket has the largest dead weight when it is first launched, and as the altitude increases, the gravity gradually decreases until it loses weight, and the acceleration becomes larger and larger. Ordinary rockets often run out of fuel at this time, but non-working engines do not.

Moreover, deep space can ignore the frictional resistance of air, and the acceleration will increase as it flies, until it is a full g more than when it was launched.

So in the end, the efficiency is not inferior to ordinary rockets at all, and there is no need to do the separation of the first and second stages like a rocket, what else do you want?

However, Ye Han also understands what the professor meant, it is nothing more than that he has no technical content, and he can do better.

I thought, can you do it in this lab? It's all about time...... Although the system is vague about the limit of playing Schrödinger, Ye Han's preset time is three days—which is easy to deduce from the previous two rounds.

Lathe machining, 3D printing, including design, assembly, commissioning...... All of this takes time!

Even if the machine tool printer is very efficient, the work-free engine is simple and leather, and the parts with little mechanical movement, time-consuming and labor-intensive tests such as reliability, fatigue, and durability can be omitted, and there is still a lot of work to be done.

Because before the game is over, he has to make the engine as perfect as possible.

Because once specified, this thing is no longer an ordinary item, and will be transformed into an attribute magic weapon.

At that time, it will not be possible to replace it with ordinary materials, and you will have to travel through various time and space streams to find suitable materials, or spend time with your own ability and will...... So one step is the best! Even if it is not in place, there is room for convenient transformation.

More importantly, in addition to the work-free engine, he has more things to build, and more theories to try to verify......

With the rules of this world broken, it is not just a non-working engine that can be made.

The system feels that the rules of the world are not uniform, and the mess and patchwork can make him unable to easily affinity with the universe, and he can't wave his hand to level everything, but he doesn't know that the building house is more leaky, and he can pick up more seams!

"Look, we could have added a turbine engine! The air intakes are cut on both sides, and the air intake channels are pre-heated around the upper part of the engine, which by the way cools the engine and then supercharged into the engine......" the professor said with his bold idea.

Ye Han was disdainful at first, but he listened to it and came to his senses.

It's not that the professor's idea makes sense, but his simple way of thinking inspired Ye Han's bolder ideas-

"Why add a turbine engine instead of an electromagnetic propulsion system? The non-working engine itself is a kind of electromagnetic thruster......"

"A set of electromagnetic cooling rings and superconducting coils are added here. The electromagnetic cooling ring maintains the superconducting state of the coil at ultra-low temperatures, and the superconducting coil generates a super-strong magnetic field, which rapidly heats the passing air to an ionic state that can be accelerated by the magnetic field......"

"This eliminates the need for fuel and adds unnecessary loads......"

This was originally a weapon conceived by Ye Han, but now that he thinks about it, it seems that he is planning to turn the Hall Thruster [Note 1] upside down and use it as a flamethrower, and now this is correct.

The professor's hairs stood up when he heard this, and he praised Ye Han again and again, "Amazing!" Bad bad !" It's almost time to kneel down and sing to conquer!

The professor is still like this, a circle of experimental dogs and the master is really kneeling.

There is no need to explain to a big star like a flower who is smiling, scrambling to sign the confidentiality agreement, for fear of being kicked out and missing this moment to witness history and witness miracles......

In short, Ye Han, who returned to college, was like a fish in water.

Because there is no need for emotional intelligence here, there is no need for intrigue, and the work-free engine is so good!

When he put it there, it was as if the tiger's body was shaken, and Wang Ba's qi leaked sideways...... Tyrant pulls off his pants!

==========

Compared to Ye Han, the others were not so pleasant.

Whether it is an NPC or a contestant, whether it is a positive or negative side, it is very unpleasant!

Because of the police's investigation and Ye Han's counterattack, the evil capital is becoming more and more chaotic.

Originally, the cyber bomb could only affect for a while, and the system would repair it automatically.

But don't the police give up, try again and again, and increase the weight again and again...... In desperation, Ye Han's cyber bombs had to be dropped again and again, blocking the network data and making the entire city unsteady; Disrupting traffic signals makes it difficult for police officers to move quickly and slows down their investigations.

In a word, the gods fought, and the people suffered.

For this chaotic situation, the opposing contestants should be happy to see it, why not be happy?

Of course not happy.

The city is paralyzed, it is inconvenient to find prey, it is inconvenient to run away after finishing the work, and it is especially inconvenient because the case cannot be broadcast on the Internet, and it is difficult for radio and television stations to interview it...... Even if they commit crimes, they can't be known.

You must know that popularity and influence are the most critical indicators for judging the success of a serial killer.

If these two can't go up, the assessment can only be tied with Douglas - half of the normal.

It is useless to be a model worker for multiple crimes, and you can only receive rewards once a day.

As for the positive contestants, they are even more unlucky!

obviously had other cases in hand, but he was forced to investigate Ye Han in various ways......

Those who have the ability do not dare to move, such as Mitnik; The ability to dare to move is not enough.

Although catching Ye Han can also resist the task, and the reward will definitely not be less, the competition is too fierce!

The previous case was sharded, and the scope of each sub-bureau was different, even if Ye Han intervened, after all, it was just one more, but now it's good...... There is this case in everyone's list, and if you count it roughly, there are more than 100 participating teams and hundreds of people.

I really hope for this, the difficulty is no less than that of Shangqing North.

So most of them obeyed on the surface, hid the fragrance in their stomachs, and quietly investigated their own cases.

But as the saying goes, there is no impermeable wall in the world.

Although the university town is remote, although Ye Han's hiding is secret, and the protective measures are also in place, it was slowly found after all.

After all, the evil capital is not big, with a population of 100,000 and thousands of policemen, and it will not take long to search for them from house to house.

If it is usually so simple and rude, there will definitely be a lot of chaos, but now that the city is paralyzed, it is not so resistant to being searched by the door, especially the culprit who caused all this...... It's an unprecedented cooperation.

But the main clues come from two places.

One is a certain master, although he signed a confidentiality agreement, he still secretly made a call to his home and was locked in the approximate location.

The other is from prison.

There was only one day left in the three days, and the chief of the police of the evil capital finally bowed his noble head to a certain criminal: "I signed your exoneration agreement, as long as you can lead the police to find Ye Han!" ”

"You said you, wouldn't it be good if you signed early? Wasting so much of everyone's time. Tom Show Killer admired the police chief's sudden bruising muscles, "Do you think I can't smell it if you cover it up like this, we are all the way?" ”

Happily listening to the system prompts in my ears, I smiled even more.
