Cosmic Survival: Sign In From The Rescue Capsule

The rotation time of this planet is actually relatively long, about 30 days to complete a day and night cycle, that is, the time of day and night, each lasting about 15 days.

As for the location of the industrial base, after landing for so many days, it has slowly ushered in the "noon hour", so in the calculation of time, there are still seven days, and the dark night of the planet will usher in!

At that time, not only will the surface of the planet become colder, but these nocturnal monsters will also be dispatched!

"Seven days.........should be still time, right?~"

Zhang Mingrui was slightly dignified, because according to his own analysis just now, the next thing to do, or – there are a lot of them.

First of all, it is necessary to develop all three technologies first, a total of scientific research power demand, 217 degrees!

At present, although the overall power generation efficiency of Zhang Mingrui has reached about 10 million kWh, if you want to make 2.1 billion, that is, 210,000 kWh of electricity, it will take at least 210 hours!

That's 8.75 days!

That's two days more than the remaining 7 days!

"Spit up..."

Zhang Mingrui wailed in his heart, if he had discovered the existence of the nocturnal monster earlier, he might have had more time to prepare.

But now, not only is there not enough time, but you must also think of some ways to improve your power generation efficiency again!

"There are two ways."

"First, continue to expand the number of power towers."

"But according to the power generation efficiency of 50,000 degrees per hour per generation tower, at least 100 to 200 must be built to greatly improve the power generation efficiency."

"Moreover, because the output rate of various raw materials is actually not very high, it takes more than a day to build so many raw materials."

Zhang Mingrui let out a long breath and sighed.

"As for the second way, it is to build that solar power tower, if you have 500,000 kWh of electricity per hour, you only need to build ten to improve the efficiency of power generation."

"But the problem with this approach is that adding a ninth-level technology study may leave me less time."

"Secondly, the solar intensity on this planet is likely to not be able to support the full power generation efficiency of the solar power tower!"

Zhang Mingrui said solemnly, a few hours ago he felt that there was nothing to do, but now he is surprised to find that there are many problems that need to be solved!

"If only the inferior matrix research station could be upgraded to perfect quality."

Turning his head and glancing at the research station that was still trying to make an electromagnetic matrix, he sighed softly in his heart.

At the moment, the AI calendar sounded!

"Zero hour chime!"

"Today is April 15, 15th year of the cosmic calendar, the 105th day of your survival in the cosmic survival race.

"Today is the day of weekly check-in, please remember to check in time!"

"Sign in now!"

【Sign in successfully! 】 】

[Congratulations to the host, get the perfect mining machine production drawings! ] 】

[Congratulations to the host for completing the weekly check-in! ] 】

[Congratulations to the host! ] Get an epic ultrasonic oscillator! 】

This weekly check-in, Zhang Mingrui did not go to the bath and change clothes, because compared to other types of lotteries, weekly check-ins are irrelevant.

But what I didn't expect was that the check-in system once again rewarded itself with two good things!

The first, the perfect mining machine, can directly increase the current resource collection efficiency by ten times, temporarily solving the problem that the resource acquisition speed cannot keep up with the component production speed when various components are made.

As for the second, the epic ultrasonic oscillator, it is related to the sound as soon as it is heard, but what is the use of it, it is not clear for the time being.

"View information!"

With an order, information slowly emerged.

【Epic ultrasonic oscillator】

[Note]: It can emit sound waves of 1 Hz-200,000 Hz, a single setting, only a single frequency of sound waves can be emitted, with functions such as attracting, driving away monsters, long-distance information transmission, ranging, speed measurement, gravel and so on.

[Resource requirements]: No, the device does not exist in the information system.

【Note】: The correct use of ultrasonic oscillator will help you solve many problems.

After reading the information introduction of [Epic Ultrasonic Oscillator], Zhang Mingrui's mood was not only surprised, but also had many doubts.

The reason for the surprise is simple, because the sound waves it emits actually have the function of driving away monsters!

The reason for the confusion is that other functions are flagged!

Ranging, speed measurement, gravel is still relatively easy to understand, after all, sound waves do contain energy, but this long-distance information legend is a little confusing.

Transmitting information in this universe? To whom to pass it on? To the monster?

Zhang Mingrui pouted, a little helpless, but nevertheless, even if it only had the function of attracting or driving away monsters, it was enough to be happy!

In this way, in the face of the upcoming nocturnal monster attack, it seems that there is already a certain self-preservation ability!

"The frequency of sound waves that bats can feel should be between 10,000 and 150,000 hertz.

... Ask for flowers...

"Mice can feel sound waves at frequencies between 200 and 90,000 hertz.

"As for the frequency at which wolves can hear, it's 15 to 50,000 hertz."

"But these data are all data on Earth, and since they are monsters, they may be different from these."

Zhang Mingrui muttered that if he could find a suitable frequency and make the sonic oscillator keep sounding, he could drive away all three nocturnal monsters at once!

But the problem is, what exactly is the frequency of sound waves that these monsters can hear, it is impossible to determine for the time being.......... This is why Zhang Mingrui said that although he got an ultrasonic oscillator, he only had "certain" self-preservation ability.

"Offense is the best defense!"

"You still have to develop two weapon technologies first!"

...... 0

Zhang Mingrui first built the [Epic Ultrasonic Oscillator] on the spaceship, and then solemnly said.

Immediately after the decision, it is better not to carry out the research and development of solar power towers, after all, it is really risky.

"Start developing the ninth-level technology [Lock Attack Technology]!"

"Ten-level technology [thermal conductivity induction technology] join the R&D queue!"

After giving these two orders in a row, Zhang Mingrui went to sleep and rest.

When you wake up tomorrow, another hard-fought battle will start again!

If you want to build a [Locking Attack Device] and [Thermal Conductivity Sensing Device], there is a raw material that is necessary, called high-energy graphite.

If you want to build this thing, in addition to the research and development of the ten-level technology [smelting and refining technology] first, you also need to collect enough coal!

"For every 10kg of coal mine, 1kg of refined coal can be smelted, and every 10kg of refined coal can produce 1kg of high-energy graphite..."

"The development of science and technology is really a money-burning thing!"

Zhang Mingrui sighed softly and turned his head to glance at the coal mining area not far away.

I thought that the coal in it was enough for a thermal power plant to burn it for six or seven or eight months.

But now it seems that if the use of coal mines increases, then the time to generate electricity will be greatly reduced!

"Uncomfortable."

"Although I don't want to move now, when the coal runs out, I still need to be forced to move!"

Zhang Mingrui muttered, although he was extremely reluctant in his heart, there was no way at all, he could only accept it!

"So, let's start building a batch of mining machines specifically to store coal mines that make high-energy graphite."

After that, a new round of battles officially started 100 million! .
