Xu Dan naturally understood the meaning of what the system said, but he had no choice but to do so.

Now he can only remind Dr. Banner and Falcon to be careful, these rare metals are indeed very strong.

Once they are not utilized properly, these rare metals can tear their bodies apart, and even ingest them during research.

The process of this kind of research is not as simple as they imagined.

"Xu Dan, you are finally back, everything in the laboratory is completely done, just waiting for your research again."

After making all the preparations, Dr. Banner spoke to Xu Dan with great satisfaction.

And Dr. Banner At the moment is really very explicit about these things.

He no longer wants Xu Dan to do something that has no chance of winning.

And he himself doesn't want to do these things that have no chance of winning, and he can even make this negative ion cannon.

Stark walked over slowly from the side, "I also found some materials, I don't know if I can use them, and these materials were obtained from the big steel country before.

After taking out some steel materials like this, Xu Dan and Dr. Banner were extremely happy.

I didn't expect Stark to actually do these things.

"Is there really so many things in this big steel country? And although these metals are second only to rare metals, there are many things he can do."

Xu Dan picked up the steel in his hand, he understood that it would be good if the steel could be integrated into the negative ion cannon.

There are even a lot of high-quality steel in it, such a steel is comparable to rare metals.

"It's nothing. On the side of the big steel country, he even gave us some crystals that they can't use."

As soon as Stark took out the crystal, Xu Dan immediately ran up and took the crystal.

He knows the function of these crystals now, and he can use these crystals as a certain line to directly pull negative ions in.

This is a circuit made of crystals, and all circuits have certain dangers, but the circuits of crystals are complete, without any danger.

"It's really great, this crystal came too timely!"

Soon Xu Dan brought these crystals over, he thanked Stark, and also thanked the big steel country.

All in all, the crystals here allow them to create a lot of circuits. Dr. Banner didn't understand what Xu Dan wanted to do at first, but then he saw Xu Dan's actions being understood.

Dr. Banner said: "|| Xu Dan let me help you, it's hard for you to do it alone."

Xu Dan nodded. It was indeed very difficult for him to complete it alone. He had to have someone to help him with what he saw.

But these crystals (Node's) are the crystals he has taken the most, and there are not many impurities in this kind of crystal.

It would be the best if it could exist as a real line.

To attract negative ions, once they can enter the realm of negative ions, it is the best choice for them to use nano-materials.

Nanomaterials are their final root, and there are those rare metals as the shell, which can also do what they want, and they are very tough. .
