Glanced at the current mission point, at 1743 points.

In terms of science and technology, due to the two tens of millions of expenditures, it is much less, but because the current super-dimensional technology is vigorously engaged in development, although the United States is oppressed, Robert's progress in Brazil has not stopped, plus the actions of Candace in Europe, a lot of money has been spent.

Therefore, there are still 63.21 million technology points.

Under Su Cheng's control, he used the [Special Zone Unlock Right] again and bought a total of 20 metal hydrogen production lines.

The mission points were instantly reduced to 743 points, and the technology points were only 43.21 million points.

Although the expenses were very large, Su Cheng only felt distressed for a while, and then stabilized his mood, anyway, the task points and technology points are used for consumption, if they don't need to be stored alone, then they will lose the meaning of their existence.

"There is one unlocking right left, you can keep it for the time being, 20 production lines of metal hydrogen are enough!"

Exiting the [Tuhao System], Su Cheng took out a resolute and resolute character, directly spent 200,000 technology points, and used perfect construction to build the 20 [Metal Hydrogen Production Lines] one by one in this underground space.

The space that originally seemed relatively empty was a little more crowded, of course, just a little.

After the construction was completed, Su Cheng frowned, and he found a big problem.

"There are production lines, but can the current underground heat energy supply so many production lines?"

The production of metallic hydrogen requires a huge amount of energy, and the electrical energy of the general power station is not enough, so the second power station chose to use underground thermal energy at the base of the volcanic island for energy replenishment.

But after all, this is the surface, and Su Cheng is also worried that because the ground is not deep, the supply of underground energy will not be sufficient after a period of time.

Considering this kind of problem, Su Cheng immediately dialed the second phone.

"Boss, what instructions do you have?" Dian Er was busy with new energy vehicles at the moment, and when he found Su Cheng's phone, he immediately connected it.

Su Cheng said: "I have built 20 production lines of metal hydrogen from the Science and Technology City, and now there is no energy supply to start, can the heat energy you drew from the underground supply these production lines?"

"Boss, small problem, the volcano where the base is located, the heat energy in it is very rich, and it is connected to the underground magma area, not to mention 20, even if it is 20,000, it can be fully supplied, but it is just ......"

"Have any other questions?" Su Cheng's heart tightened.

"No, it's just that I'm still in Paris, and the heat converter doesn't have it at the base of the volcanic island. Dian Er said: "However, since the tunnel between the volcanic island and the second research institute is open, you can actually go over there and take the nuclear fusion device back and place it at the base of the volcanic island, in that case, it will be more convenient to directly use nuclear energy to drive the metal hydrogen production line than underground thermal energy." ”

"Damn, you said it earlier. Hearing this, Su Cheng rolled his eyes and went around, the conversation just now was equivalent to not saying anything.

"Uh...... It was the boss who asked me first, and I can only explain it to you slowly. Denji smiled wryly.

"Alright, I don't blame you. That's it for now, hang up. ”

Ending the call, Su Cheng got on the supersonic train and rushed to the second research institute non-stop.

The supersonic train is worthy of being a high-tech product designed by Electric Er, and with the cooperation of the Science and Technology City Tunnel, the 20,000-mile area from the volcanic island to Silicon Valley has been successfully crossed in just 100 minutes.

It is no exaggeration to say that if Su Cheng unveils this tunnel and supersonic train, they will become an epoch-making way to travel, and with the protection of the tunnel, the safety is almost 100%.

The ultra-fast speed and ultra-high security will shock and even drive the whole world crazy.

However, Su Cheng is not so stupid, this kind of strategic tunnel, it is better for him to know it alone, and outsiders don't want to know.

After arriving at the Second Research Institute, Su Cheng and Wu San met.

When he saw Su Cheng, he was very angry and wanted to hug him, but when he saw his dirty body, Su Cheng avoided it in disgust.

"You guy, why are you so dirty, you have to love cleanliness, you're a robot. ”

Wu San smiled, full of care: "Boss, I'm such a person, clean when I should be clean, sloppy when I should be sloppy, isn't this doing research." ”

"Well, have you had any new inventions recently?" Su Cheng didn't bother to discipline him.

"Yes, I've been working on airplanes lately. "Wu Sandao.

Engage in airplanes?

The corners of Su Cheng's lips twitched when he heard this, and he coughed lightly: "What kind of plane?"

"Well, it's a 'Dark Dragon Fighter' in my memory bank. ”

"'Dark Dragon Fighter'?" Su Cheng was a little interested when he heard this novel name.

Wu San explained: "The 'Dark Dragon Fighter' is a super fighter, it has a maximum flight speed of Mach 10, a sonic cruise speed of Mach 7.2, and is equipped with a night-to-day perspective, and the combat efficiency at night can reach 90% of that during the day. ”

"What's even more powerful is that the 'Dark Dragon Fighter' also has the electromagnetic field to control the sonic boom, and it will hardly make a sound when flying, even if it flies at a speed of Mach 10, the sound it emits will not exceed 80 decibels. ”

The sound of 80 decibels sounds very loud and noisy in normal times, but at an altitude of thousands of meters or even tens of thousands of meters, this decibel volume cannot be heard by people on the ground at all.

"In addition to these, the 'Dark Dragon Fighter' can also emit electromagnetic disorder in the field, within a radius of thirty kilometers, it is impossible to locate its figure with radar, of course, I am talking about the first-generation 'Dark Dragon Fighter', if it is upgraded to the fourth-generation fighter, it will have a real stealth effect, which cannot be seen by the naked eye. ”

"However, the fourth-generation 'Dark Dragon Fighter' needs sound-absorbing steel and many high-grade materials, which are not available on the earth. ”

Hearing Wu San's introduction, Su Cheng was excited at first, but as he spoke, Su Cheng calmed down.

After finishing speaking, Su Cheng said lightly: "After talking so much, how long will it take for you to get the 'Dark Dragon Fighter' in your mouth?"

"Uh...... Well, I don't know much about this, it's half a year, and it's a long, long time...... "Wu Sanzhi is authentic."

"I know that. Su Cheng glared at him.

Wu San said: "Ahem, boss, if you can be promoted to the epic level as soon as possible and update my database, then the 'Dark Dragon Fighter' will only be able to do well in two months." ”

Su Cheng rolled his eyes, he thought, but is the epic system so easy to upgrade, you need to complete the mobile phone task to trigger the upgrade task, it's still early.

However, Wu San's words made Su Cheng pay more attention to this matter in his heart, it seems that this mobile phone task must find a time to speed up, of course, it can't be rushed.

Taking the elevator, Su Cheng entered the ground of the Second Research Institute and came to a hidden laboratory, "Now that the tunnel between Huaxia and the United States has been opened, if you want to, it is best to go back to the base of the volcanic island to conduct research, and after a while, the tunnel to Sehgal will be opened, you go directly over there to do it, even if the island is blown up, no one will care about you." ”

"Hehe, that's a good feeling, but, in fact, I haven't been engaged in weapons for a while, mainly in the study of fighters and submarines, in addition to the dark dragon fighter, I also have some complete ideas for the drawings of nuclear submarines. Wu San said with a smile.
