City: I'm Really Not Rich

"This is the high-power mode of the Titanium Energy Knife, as well as the long-range attack mode."

Wan'er smiled and didn't care about the rumbling of the sea behind her. She skillfully operated the knife in her hand, and then handed Zhang Chen a telescope.

Then he raised his knife and stabbed the sea on the other side. Zhang Chen didn't see anything, but a small reef island in the farthest field of vision suddenly exploded.

Although no sound can be heard, the feeling of the rocks splashing still makes people feel a thrilling feeling.

Wan'er didn't think so, she happily returned to Zhang Chen's side.

"The titanium energy knife can also have a higher range, but your telescope can only see so far, and you can't observe 247 any longer."

Zhang Chen had a smile on his face, and his heart had turned into a Roaring Emperor.

Which planet's black technology is this? Such a small knife is more powerful than a rocket launcher, right?

If a civilization with titanium blade technology could also have guns and cannons, wouldn't it be possible to directly level the water blue star with one shot?

"Master, the titanium energy knife has a precision shooting mode, as long as you want, you can blind the fly's eyes without hurting its life, I will show you again..."

Wan'er was still enthusiastically introducing this titanium energy knife.

Zhang Chen waved his hand without (ajcj) force.

"No need to introduce, I'll give you this knife.

He has no interest in this black technology of mass destruction. Since Wan'er seems to like it so much, he just gave her a favor.

Sure enough, Wan'er's eyes blushed when she heard it.

"The owner of such a precious thing is really willing to give it to Wan'er?

"Well, precious things are just right for you. 35

Zhang Chen smiled and said.

Wan'er knelt on one knee and lifted the titanium energy knife above her head at once.

"Wan'er swears to protect the master to the death. No matter what happens, Wan'er and the dark guards will be the master's toughest shield and sharpest sword. Your glory is our glory!"

"Well, okay, you go back first.

Zhang Chen lay down on the sun lounger, took a sip of coconut juice and calmed down, and waited for the sea to calm down before starting the third lottery draw.

He understands that this advanced lottery is similar to those krypton gold games played before, the prize pool has expanded several times, there are things that are much better than the ordinary lottery, and some are only a little better than the ordinary lottery.

What can be drawn depends on the face.

"Okay, another shot!"

Zhang Chen chose the third lottery draw, and he once again stood in the starry sky.

Finally, the system dinged, and a starlight fell in front of him.

Congratulations to the host for drawing the technology optional box: you can choose one of the four boxes for sea, land and air people, and there will be a technology that can change the development of civilization at this stage.

Note: The host obtains all theoretical knowledge of this technology, as well as all secondary technology knowledge required by this technology. In addition, a copy of physical data will be presented, including all theoretical data, excluding experimental data.

what?

Technology that changes the development of civilization?

This sounds like a very cool look. If you choose "empty", is it possible to get the curvature engine technology directly, so that humans can become space creatures in minutes?

Zhang Chen sat up unconsciously.

He realized that after he had hacked two hands, he might have drawn an epic divine outfit.

His eyes fell on the four boxes in the void, and his heart began to tangle.
