Dong Chen originally paid attention to the game world, but he didn't pay much attention to this door-like thing, after all, this was too high-end for him, and he couldn't start if he wanted to study it, and it was far from being as real as what could be seen and touched in the game world.

However, Dong Chen looked at the neat incision in front of him in a daze, some of the materials on the shelf that were not neatly placed and stretched out were all cut, and they generally looked like a circle, which was exactly the size of the arc door that had been opened before.

Speaking of the size of the arc gate, he never figured it out, it turned out that it was two meters when it was unfolded at the beginning, and his height of one meter seven or eight was just right when he walked in, and then when he wore two meters and two power armor to enter, it automatically rose to about two meters and four.

Two days ago, he also tried to expand the limit, but his biggest venue now is the laboratory, with a height of six meters three, so he only expanded to six meters two, he feels that this expansion is not the limit, it can be bigger, but it is just tested here, and the experiment will be wasted outside.

And he found that the size of the expansion has nothing to do with the energy, no matter the size is 10%, is it actually the same size of the channel opened each time, but what he sees is this? But this neat cut counts as something about.

Then he took a steel pipe from the shelf, then walked to the center of the field and opened the arc door, looking at the neat arc edge and the small arc that kept jumping inside, he stretched the steel pipe in, and then slowly moved to the edge, and when he moved to the edge and broke through the edge to come out, the steel pipe was not shortened by the edge as he imagined, but intact.

Isn't the clearly visible edge the actual edge? Or is it the reason why I'm moving from the inside out?

He then took the pipe and moved it from the outside to the inside, but after passing the edge, the pipe was still intact.

However, Dong Chen had already noticed that he was holding the steel pipe at this time, could it be his own reason?

Looking back at the material rack that had been cut like that, I confirmed this guess.

He then tested the inside-out and outside-in experiments with the throwing method, and when the steel pipe flew from the outside to the inside, the edge of the arc gate was cut open, and the two halves of the steel pipe did not disappear in the real world. Then you put the steel pipe into the arc door and throw it to the edge, and it will also be cut in half, except that the first half is in the real world, and the second half is gone.

Dong Chen also deliberately went in to take a look, and sure enough, he fell into the game world, because he opened the door twice over there, the energy to come in and go out this time was not enough, so he could only do experiments here.

But there is also a good thing about this world, that is, you can wave casually.

I saw Dong Chen come to the open space outside the shelter, controlling the circular arc door to fly around, he didn't know what he was using? Is it mental power or mental power, or is it useless, anyway, the arc gate is flying around with his thoughts.

When he shrunk the arc gate to a centimeter in diameter, he found that he was flying faster, and he only saw a blue trail in the air, which was extremely beautiful and dangerous.

I saw that those things on the blue flight trajectory were either cut off or pierced through a hole, and they really flew to where they were destroyed, and this is still the arc gate used to cross the world, this is obviously a flying sword, okay.

Later, he tried to expand the limit again, and when he spread to more than ten meters on the ground, he had to move to the sky, because the building next to it was cut off a piece, and in the sky it did not stop until it was magnified to a diameter of two hundred meters.

That's big enough.

And on the problem of energy consumption has also been experimented, it is indeed a fixed consumption of 10% of the energy every time it is opened, and with the length of time to expand, it will also consume a part of the energy to maintain the expansion of the arc door, and the speed of energy consumption is about twice the speed of charging, that is, it takes a day to charge, and if you open the arc door without crossing, it will also close after half a day because of energy exhaustion.

Later, when waiting for the energy to recover, Dong Chen sorted out the data of the water purifier again, these are no longer the original paper materials, they are the Chinese electronic materials that Dong Chen translated, and the schematic diagram was also drawn after redesign.

And he also made a combination according to the realistic scientific and technological situation, the equipment is not the original appearance at all, except for the core filter membrane has not changed, some parts have been replaced, although the performance has been weakened by 15%, but the product in the face of the real world still occupies a great advantage.

It's just that when Dong Chen waited until the charge was completed and returned to the real world, the corners of his mouth twitched a little when he looked at the mess in this place, this ...... Patronizing and playing handsome over there, all the things that have been cut off are thrown here.

Okay, cement, bricks, rotten wood, waste steel bars, Dong Chen threw these all back, and swept the ground again, and the vacuum cleaner sucked it all before he cleaned up all those things.

But it's all worth it, and a new feature has been developed.

…………

Inside Sun Hao's office.

Dong Chen and Sun Hao were sitting on the sofa in the hospitality area, while Sun Hao was looking at the screen of a laptop, but Dong Chen was pointing at him from the side.

“…… It can improve the efficiency by three to four times, but the energy consumption is not even half, as a whole, if the same energy consumption, it will be eight to ten times that of ordinary water purification equipment, and its cost is not high relative to the same type of equipment, it can be popularized, these things for occupying the market, you must know more than me, and the specific operation is your strength. Dong Chen finally said to Sun Hao.

"Well, if the technology you said is okay, it is entirely possible that it will become one of the pillar industries of our company, but its core is chemical products, it seems that we have to acquire a chemical plant, and other parts can be produced by us, and even downstream industries can be done together." Sun Hao nodded affirmatively and said.

"There must be a lot of money needed, we don't have it at the moment?" Dong Chen said suspiciously.

"Loan, according to our company's rising potential and your technology, the loan is no problem at all, you don't understand it if it's too professional, after all, you don't learn this, you just need to know that we are going to go on the fast track." Sun Hao said with a smile, with a confident look on his face.

"Okay, I don't understand this, I just need to provide you with technology, and I have to trouble you to apply for a patent, it turns out that Brother Lin helped to apply, and he can only rely on you when he leaves, I am not very good at this aspect, it is too troublesome, the main thing is that this technology does not have too many scientific and technological barriers, otherwise I am too lazy to care about this matter." Dong Chen said helplessly.

For a student who has just walked out of school, this kind of thing is really troublesome, especially because of his personality, and he chose an art major, although he is now a career changer, but after so many years, the whole person is still a little bit literary and artistic, and he is most afraid of trouble.

Maybe the more things I come into contact with in the future, I think I will have new feelings.

No way, living in this big dye vat-like society, it's not so easy to be alone, so there is still a lot to learn.

"I know, you scientific researchers, technical nerds and other things are all in this problem, but your invention this time is not simple, haha, no wonder Lao Lin admires you so much." Sun Hao said with a smile, and praised him again by the way.

"Ahem, it's actually not my invention, it's an invention made by a few of my buddies and me, how do I know so much, you also said, technology nerds, many people don't want to show their heads, it just so happens that I know so many tech nerds, I'm very cheerful, so they ask me, hehe." Dong Chen said embarrassedly.

I can only let my buddy go online, otherwise I can't resist so many things now.
