Suppressing the excitement in his heart, Su Cheng walked through a blue corridor, and then took the elevator to the next floor and entered a huge workshop.

In the workshop, hundreds of small workers and robots are walking back and forth, and all kinds of raw materials are sent by transport trucks, and then turned into basic parts and large objects are carried away.

Standing in the center, the huge 3D printer is rumbling into operation.

Every day's operation requires up to 500 million soft girl coins worth of technology points.

"Boss!" Su Cheng walked over, and a small worker robot in charge of commanding hurriedly greeted him respectfully.

"Well, tell them all to stop what they're doing. Su Cheng commanded.

"Yes!" the robot yelled at the working robots, and then they quickly straightened out the work at hand.

Then they were neatly arranged to the side, waiting for Su Cheng's lecture.

However, Su Cheng didn't lecture today, walked to the front of the 3D printer, and silently recited it.

In an instant, the huge fuselage suddenly disappeared, and the robots present were all products of the Science and Technology City, so no one was surprised, they just stood in place, looking ahead without squinting.

Immersed in the system, Su Cheng hurriedly checked the upgrade needs of the 3D printer.

[Epic 3D Printer: 1000 mission points and 100 million technology points required for upgrade]

Note 1: There is a fundamental difference between an epic 3D printer and an advanced state.

Note 2: The upgrade took 240 hours.

Note 3: After the upgrade is completed, the Epic 3D printer will be larger and occupy a wider area, so please prepare your host.

Bite!

[Epic upgrade coupon detected in the inventory, please ask the host, whether it is used for 3D printer upgrade]

"Grandma's, it's really expensive, it's as high as a thousand mission points!"

Su Cheng secretly said in his heart Sure enough, he knew that the 3D printer was a thing that went against the sky, and it took a lot to upgrade.

I don't mention the technology points, the important thing is the task point, and it actually needs a thousand points.

This is the most expensive single consumption Su Cheng has ever seen.

But fortunately, when I was lucky in the lottery before, I drew an epic upgrade coupon, which happened to be used to upgrade the 3D printer.

The system sent a prompt, Su Cheng did not hesitate, and after a little slander, he used the epic upgrade coupon to make the 3D printer enter the upgrade sequence.

Bite!

[It will take 239 hours, 59 minutes and 56 seconds for the 3D printer to reach an epic state]

Immediately after, the time it took to upgrade into Su Cheng's ears made his heart move.

Speaking of which, the [local tyrant system] is not as long as the time required for a 3D printer to ascend to the epic level.

Of course, the length of time it takes to upgrade does not indicate whether the item is powerful or not.

After all, the system dominates the Science and Technology City, and the 3D printer is a product of the Science and Technology City, of course, the system is more powerful.

"240 hours, 10 days, that's a bit long. ”

While chattering, Su Cheng came to the [Special Zone].

In the [Special Zone], find the purchase section of the [100 times time variable card], check it, and find that the purchase is still required for 100 task points.

Without much hesitation, he glanced at the remaining 1986 task points, and Su Cheng directly crossed out a hundred and bought a [100 times time variable card].

Then, it is directly used in the upgrade of the 3D printer.

In an instant, the 240 hours required for the upgrade were suddenly reduced to 2.4 hours.

In just over two hours, it was not a problem for Su Cheng.

However, when the 3D printer was upgraded in the Science and Technology City, Su Cheng left the workshop in order to pass the time, took a supersonic train, and went straight to the Segal Islands.

As early as when Su Cheng was drawing, he took some of the robots to Segal.

It took about an hour and a half for Su Cheng to successfully cross the land in the southwestern part of the Indian Ocean.

Wu San got the notice of Dianyi and knew that Su Cheng was coming, so he had already stopped what he was doing and came to the tunnel exit to greet Su Cheng.

"Hehe, boss, I miss you to death, long time no see. Wu San's big grinning personality will not be hidden in front of anyone, and when he saw Su Cheng, he actually wanted to hug him to show his closeness.

However, when Su Cheng saw his ragged appearance, he pointed at him with disgust, so that his movements could only be stopped.

"I heard that you got a 'controlled nuclear fusion device', where is it?" Su Cheng said.

"That thing, I put it under the dock, under the seabed, do you want to see it? Wu San replied.

"Forget it, there's nothing to see. But is your 'controlled fusion device' elementary or intermediate?"

From the introduction of the 'Nobby Air Cargo Ship', Su Cheng learned that the division of the nuclear fusion device corresponds to the level of the system.

The lowest beginner, the current highest is epic.

"Of course, it's a primary, intermediate fusion device that takes longer to prepare. By the way, boss, my database has changed, and I guess you've taken the system to epic, right?"

"Well, not long ago. Su Cheng said: "The upgrade is complete, in addition, I also got some good things in the Science and Technology City." ”

"Good things?" Wu San's eyes lit up, "What are they?"

"There is a set of construction materials for the 'Dark Dragon Fighter'. Su Cheng said.

Hearing this, Wu San's originally bright eyes darkened, and he pouted: "Boss, I don't need that thing now, I've been researching the 'Dark Dragon Fighter' recently, and now that the database is upgraded, it will be able to come out soon, and the construction materials won't help me much." ”

Speaking of this, Wu San smiled again: "But boss, if you can take out the production line of the 'Dark Dragon Fighter' from the Science and Technology City, it will be amazing." ”

"The production line? Su Cheng's heart moved, and he sank half of his mind into the [Tuhao System], and then entered the temptation of Mo Lido.

At a glance, Su Cheng's face darkened.

"Five hundred task points, ten million technology points, such an expensive one, rob people!

"Ahem, boss, in fact, it's not expensive, the performance of the 'Dark Dragon Fighter' is superior, if there is a production line, we can fix mass production, ten planes a day, one billion dollars, that's a lot of money." ”

Wu San rubbed his hands, coughed lightly, and hurriedly tried to persuade Su Cheng in his own way, but unfortunately, his ability to persuade people was not enough, and the reasons were not sufficient.

"Go, go, the 3D printer will be upgraded immediately, and when it reaches the epic level, I will explore and study the production line by myself, and 500 task points will be too expensive. Su Cheng didn't even think about it, and refused directly.

"Boss, it's really not good, the information of the production line can also be used. Wu San retreated and whispered.

"What's the information?" Su Cheng glanced at it and found that there were many fewer task points and technology points, but after thinking about it, he still didn't agree to him, and just said that he would talk about it later.

"Boss, you're too picky. Wu San was quite resentful.

"Go, dare to bury me, believe it or not?" Su Cheng scolded with a smile, and then said: "There is also a 'Nobby Air Cargo Ship', you know this thing, right?"

"'Nobby Air Freighter'?" Wu San's eyes moved, "This is a good thing, equipped with an advanced strong magnetic engine and a primary nuclear fusion device, it can be amphibious operation, even if it is suspended for ten years, it is not a problem, you take it out quickly, I have not seen a large freighter in Science and Technology City for a long time, and my heart is itchy." ”
