Chen Zheng handed Xiaoxiao to the skinny monkey to take with him temporarily, and he went up to the top floor of the main account building......

Here, the whole floor belongs to Lao Xia.

"Tuk Tuk ......"

Chen Zheng knocked on the door at the end of the stairs.

"Please come in."

Lao Xia's voice sounded from inside the door.

Chen Zheng pushed the door in, and the first thing he saw was an unusually wide hall. It's just that the hall is now full of messy furnishings, and many things are connected to thick wires, which look like some kind of incredible scientific instruments......

If someone who is unfamiliar with this place suddenly comes to this room, it is easy to bump into your head or trip over the mess under your feet with just two steps.

However, Chen Zheng is already very familiar with this place, and many of the equipment is even made and installed by himself, so it should be said that he is the second person who is familiar with this place in the entire base.

As for the first ...... That was naturally Lao Xia himself.

"Coming? Wait a minute. Lao Xia pulled down his glasses and looked at Chen Zheng, smiled and beckoned him to his side, and then put on his glasses again and was busy with the work in hand.

Chen Zheng looked down and felt that the parts looked familiar, but for a while, he couldn't remember where he had seen them.

"What are you?" Chen Zheng finally couldn't help but ask.

"Hehe, a simple testing tool." Lao Xia smiled, "Originally, I was going to manufacture the tidal gate at full speed, but some parts were not always in supply......

"Well, my question ......" Chen Zheng had a good attitude and wanted to admit his mistakes.

“…… No, it's not just you, I still have some theoretical things that I haven't fully figured out, so while you're making parts, I'm thinking about some things...... It doesn't delay. ”

Lao Xia waved his hand: "But that's not what I'm going to talk about today...... You know, the bottleneck is the gravitational wave problem. I did a lot of calculations last night, but I didn't get a solid answer in the end......"

"Then I suddenly remembered that I had built a gravitational wave generator before, so why not make another one and work backwards from the results? And then ......."

Lao Xia patted the thing in front of him.

“…… I remember, it's a gravitational wave generator! Chen Zheng was stunned. Previously, the core component of the zero-pressure generator was the gravitational wave generator.

"That's right, that's it." Lao Xia smiled, "And then you also know the result...... I couldn't figure out how he worked then, and it's the same today. ”

Lao Xia shook his head, but he still had a smile on his face, as if he was deliberately selling Guanzi.

"But you must have made a new discovery, huh?" Chen Zheng asked.

"Hey, that's right." Lao Xia took out the two gravity wave generators and handed one of them to Chen Zheng.

"What is this?" As soon as he got his hands on the heavy machine, Chen Zheng noticed its strangeness - the gravitational wave generator had a semicircular mass of metal at the front, and at the end of the gravitational wave generator was a screen the size of a mobile phone.

"What is this?" Chen Zheng was stunned.

"Some of my small modifications were commissioned by Brother Eye's help." Lao Xia looked very proud.

"After working on gravitational wave generators without success, I wanted to study the nature of gravitational waves indirectly through the force field generated by gravitational waves blowing on zero crystals...... But you know, I don't have any scattered crystals in my hands. ”

Lao Xia said as he took another round piece of zero crystal.

"And I didn't have a way to process the zero crystal myself, so I couldn't carve it into the shape of the previous zero pressure generator, so I found two semi-circular zero crystals that you cut before, and installed them according to the spirit pressure generator......"

"No wonder ......" Chen Zheng looked at the huge "flashlight" in his hand, and couldn't help but cry and laugh.

Chen Zheng still remembered that this piece of zero crystal was accidentally cut when he killed the insect man before, but fortunately, the cut was relatively symmetrical...... Otherwise, these two instruments are not "flashlights", but "sickles and axes......

"But because of this, I discovered a detail that I hadn't noticed before." Lao Xia is colorful.

After speaking, he didn't continue to explain, but adjusted the two "flashlights", and handed one of them back to Chen Zheng after setting the parameters.

"You take this to the front, I'll take this to the back."

Obviously, he was going to demonstrate his new invention.

Chen Zheng curiously took the "flashlight" and walked to the end of the hall, while Lao Xia stood at the other end of the hall.

"Now, you look down at the screen......" Lao Xia shouted from afar.

"Good ......"

“3、2、1……”

"Buzz ......"

With the end of Lao Xia's countdown, the "flashlight" in Chen Zheng's hand suddenly shook slightly - if it weren't for Chen Zheng's extreme sensitivity and early attention to the "flashlight", otherwise such a weak vibration would have been suddenly dropped by him.

"Sorry, the following 500 have not been written, and I will fix it later."

Finally, I wanted to study the nature of gravitational waves indirectly through the force field generated by gravitational waves blowing through zero crystals...... But you know, I don't have any scattered crystals in my hands. ”

Lao Xia said as he took another round piece of zero crystal.
