It is expected that Zhang Chen can succeed and create this cross-era product.

"Secretary, keep these drawings well, and add a few more insurances, this is the hope of mankind to rise in the apocalypse!" Cao Bing was extremely solemn and handed over the drawings to the secretary.

Zhang Chen left the Business Friends Alliance.

When you get home, take out the various appliances from the printer's storage interface and disassemble them to get all kinds of metals.

Input all kinds of metals into the printer and successfully print out the [Nuclear Power Device].

Zhang Chen tried to install the nuclear energy device on his arm, he tried to move his arm, and the small and portable nuclear energy device did not affect his activities.

"Try the energy converter above." Zhang Chen installed the matching spray gun module on the peripherals of the conversion rate.

At the flip of a switch, the nuclear energy is converted into electricity, and finally a high-temperature blue flame is ejected from the long tube of the spray gun.

The use of nuclear energy devices requires almost no complicated operation, and only needs to be equipped with corresponding peripheral modules according to their own use.

Among the included modules, there are a large number of tool modules, which are enough to meet the needs of most scenarios.

"The nuclear energy device can also be installed with a thermal weapon module to fire plasma shells, which is very sci-fi, and for safety reasons, the opening of thermal weapon modules should be restricted in the later stage."

If the thermal weapon module is opened, you can imagine what kind of impact it will have in the end of the world without legal constraints.

Humans may also use this weapon to kill each other.

If the nuclear device falls into the hands of the good people, it is better to say, but if it falls into the hands of the bad people, it may directly lead to the destruction of mankind.

Therefore, it is necessary to limit the production of thermal weapon modules, and even close the corresponding peripheral drawings for destruction.

"Brother, what's this on your arm?" Zhang Yuxi asked.

When Zhang Chen was testing the nuclear energy device, he was discovered by Zhang Yuxi.

"This is a new product that I just printed, with this thing, you can play a lot of new tricks, if you want, I will print one for each of you."

Zhang Chen printed four more copies of the materials.

This kind of sci-fi product should be a copy for everyone, and for its own people, it is necessary to open up the thermal weapon mod.

This thing is usually outdoors, not only a guarantee of survival, but also a lifesaver in times of danger.

Zhang Chen gave the things to Zhang Yuxi and asked her to send them to everyone.

As for the instructions for use, in fact, there is a schematic diagram on the product, and it is very easy to use, you only need to switch the module, and you can understand it by looking at it.

Zhang Chen privately took out the Rubik's Cube he had picked up earlier.

This thing had fallen from the alien UFO before.

Zhang Chen didn't understand this thing at all, but it was because of this thing that he activated the sci-fi module.

This Rubik's Cube looks ordinary, but it contains technology that Zhang Chen doesn't know.

That is, when the Rubik's Cube is turned, the color of the square will automatically change to another order, which makes Zhang Chen puzzled.

Perhaps the changing color blocks on the Rubik's Cube are hiding a kind of information.

Zhang Chen turned the Rubik's Cube in boredom, no matter how he turned it, he couldn't make the Rubik's Cube return to its original state.

Perhaps to unlock this Rubik's Cube, it will take wisdom that transcends the times.

If it is an ordinary Rubik's Cube, Zhang Chen can solve it simply by using the formula.

Even if he doesn't use formulas, then with his spatial logical thinking, he can still solve it with some brains.

But there is no law to follow in this Rubik's Cube, it is more like a school of natural constants, infinite is not cyclical, there are endless possibilities.

After turning around for a while, Zhang Chen just made the color blocks on it more chaotic and complicated, and other than that, there was no new progress.

Tastelessly throwing the Rubik's Cube back into the printer's storage space, Zhang Chen chose to continue to meditate cross-legged and cultivate aura.

As he continued to cultivate day by day, finally tonight, Zhang Chen successfully condensed the aura into the shape of a vase on the palm of his hand.

The third final account is preliminarily grasped.

In a week's time, he initially mastered the third decision, and Zhang Chen felt that this progress was very fast.

Perhaps with the help of the special function of the Imperial Object, he has gained some advantages in controlling the aura.

"Continue to work hard and strive to be proficient in condensing the form."

"It took me almost an hour to condense this vase, and then it should be shortened."

Zhang Chen was once again immersed in aura cultivation.

He condensed the vase in the palm of his hand again, and this time it took only forty minutes, which was significantly faster than before.

But that wasn't enough, all he needed to do was condense the form in a minute.

The third duel is to prepare for the fourth, so the time to condense must not be too long, otherwise the enemy will kill him at that time.

"I can only compress the time to less than thirty minutes at most tonight." Zhang Chen saw that the sky was slightly bright outside, so he was ready to lie down and sleep.

The next morning, he remembered that Lu Bu hadn't come back yet.

After being separated the night before, Zhang Chen separated from Lu Bu, and then Lu Bu lost his whereabouts.

This made Zhang Chen worry.

It wasn't until noon that there was a knock at the door.

Zhang Chen went to open the door, if there was no accident, it should be Lu Bu who came back.

However, after opening the door, there was a big man standing two meters and three meters tall outside.

The big man wears brown shorts and a white shirt, and he is powerful.

"Are you ......" Zhang Chen hesitated when he saw the big man who was a few centimeters taller than himself.

The person in front of him was a great threat to him, and Zhang Chen didn't know him.

Could it be someone from the Hangcheng Jindan Cultivator Alliance?

It shouldn't be, because the location of the base has changed, so it won't be easily approached.

"Lord!"

The man called out directly to Zhang Chen and revealed his identity.

"Lu Bu?" Zhang Chen was surprised.

"You've grown up?" Zhang Chen asked again, circled around Lu Bu, and said, "What did you eat to grow up?" ”

"It's that King Kong, I ate it, and it grew to its peak state." Lu Bu said.

What was in front of him was not a bloody corpse, but a man with human skin, and he had a handsome appearance, even completely different from Lu Bu when he was a child.

No wonder Zhang Chen couldn't recognize it.

"King Kong was eaten by you?" Zhang Chen was a little unconvinced, such a huge monster, how long would it take to eat.

"Ate me for two days, but in the end, he lived up to his mission and successfully transformed his flesh and blood, and now I'm at my peak, and it's earth-shattering to shoot at will, if you don't believe it, please see it."

Lu Bu said, with a movement of his hand, a ball of blood condensed in the air, transforming into various forms, and even evolving a war in the air.

"Okay, I believe you are powerful, put it away quickly, otherwise it will be discovered by the cultivators, and I will think that the blood corpse will come back." Zhang Chen hurriedly reminded.

The blood corpses have now been wiped out by the Alliance of Cultivators and the Strangers.

Although Lu Bu didn't look like a bloody corpse, he was actually still a bloody corpse, and his different knowledge had an extra human skin.

But when it comes to really fighting, he is still the bloody corpse Lu Bu.
