The scientific research system has been studied many times before by Mu Feng.

What to do first, what to do next, has already been planned, tomorrow after Neptune wakes up, let her go to work in the scientific research center, and then she can start working.

What Mu Feng cares about is new, the facility upgrade function, the port area expansion function, and the design drawings of intelligent construction machines.

Facility upgrades can improve the overall performance of port facilities, such as resource collection stations, which can increase the speed of resource output.

The function of the port area expansion is to increase the overall size of the port area and add new buildings and facilities.

Whether it's expansion or upgrading, there are two options.

Take, for example, resource harvesting facilities.

The first way is to directly spend resources to purchase a set of collection facilities from the system, which requires 150,000 resources, and then the construction time is 12 hours.

Every time you buy in the future, it is 150,000 resources, 12 hours, it is always fixed, the whole process does not require human intervention, and you can choose the installation location when you buy.

The second option, built manually using smart construction machines, where raw materials are sourced from nature as much as possible.

Critical, core, and special components and materials that are temporarily unavailable are produced through the manufacturing center, which consumes resources and is handed over to the construction machine for assembly.

In the second way, the corresponding basic industrial facilities need to be built first, and the time and resources required for this process are affected by the environment and have great uncertainty.

After the completion of basic industrial facilities, it is estimated that only 50,000 resources will be needed to build a set of resource collection facilities, or even lower.

The exact amount of each subsequent construction depends on the completion of the industrial base.

In short, the first way is to buy and buy, and the second way is to do it all myself!

As a Chinese who has suffered countless losses, Mu Feng certainly chose to do it himself.

Mufeng directly selected the manufacturing equipment in the manufacturing center, and used the drawings just obtained to start producing intelligent construction machines.

An intelligent construction machine requires 100 points for each of the two resources and takes 30 minutes.

Mu Feng glanced at the time, it was 0 o'clock in the morning, and he chose to produce 16 units first, and it was expected that the production would be completed at eight o'clock tomorrow morning, and after he woke up, he just started to learn how to use them.

After all this was done, Mu Feng was really sleepy, so he shrank directly into the quilt, closed his eyes and prepared to sleep.

At this moment, the monotonous sound of music of two different heights and rhythms, constantly repeating and alternating reverberations, sounded outside the window.

Mu Feng opened his eyes suddenly, this is the radar alert in the port area set by himself.

This music represents a Level 1B alert, indicating that there is a bathyscapital fleet of less than 6 vessels, and it is within 100 kilometers of the port area.

This kind of warning level is not high, so it is not loud, but it can also be heard by the whole body, and it is enough to wake Mu Feng himself.

Mu Feng listened attentively for a while, and the corridor outside the door sounded the sound of hurried footsteps, and three people ran out of the room one after another, it should be Liaoning, Changchun, and Taiyuan.

The three of them said a simple word, two went back to the room, and one went to the dock.

After a while, the roar of fighter jets came from the direction of the pier, indicating that Liaoning had gone to eliminate this wave of deep sea.

Mu Feng once instructed that all the battle-based ship mothers, as long as they found the deep sea, as long as they could be destroyed, they could be destroyed, without waiting for their own orders.

If you sink the deep sea, you can get loot, and there is a high probability that you will get resources in the loot lottery, as long as you don't lose the battle, you won't lose the battle.

In order to be able to take the initiative to turn the ship into a hull as soon as possible, Liaoning is particularly attentive to deep-sea combat, and when it hears the alarm, it immediately gets up and takes the initiative to go out to destroy it.

Since Liaoning went, there was no need to worry about safety at all, Mu Feng closed his eyes and continued to sleep.

After coming to this world, Mu Feng has developed the habit of going to bed early and getting up early, he hasn't stayed up all night for a long time, and now it's early in the morning, and he almost fell asleep directly as soon as he closed his eyes.

I don't know how long I slept, but in a trance, I heard the alarm again, and then the sound of the fighter jet, Mu Feng opened his eyes in a daze, and found that there was indeed a sound outside, or a level 1B alarm.

Mu Feng subconsciously glanced at the time, it was now 1 o'clock in the morning, and he couldn't help frowning slightly.

I slept for an hour, and before I went to sleep, there was a deep sea attacking, and now after an hour, there is a deep sea again, is the frequency of this deep sea activity increased?

However, the deep sea within 6 is not a threat to his port area and ship girls at all, Mu Feng didn't care much, closed his eyes and continued to sleep.

An hour later, at 2 a.m., Mu Feng was woken up again by the sound of sirens and fighter jets.

Or a level 1B warning, within 6 deep seas, 100 km range.

Mu Feng resisted the urge to burst into foul language, turned his head and continued to sleep.

At three o'clock in the morning, Mu Feng was woken up again, and it was still the sound of Class 1B sirens and whizzing fighter jets.

Mu Feng exhaled helplessly, looked at the extraordinarily fragrant Crimson who had been sleeping next to her, and began to envy her a little in his heart.

Mu Feng doesn't have to worry about fighting, it's just that this voice is too annoying.

I can't turn off the alarm yet, in case a large-scale attack is carried out, and they are approached near the port area, the damage will be immeasurable.

Mu Feng burrowed into the quilt with a bitter face, covered his head and slept, praying in his heart not to ring.

However, the matter was far from over, and in the time that followed, sirens sounded every hour or so.

After Liaoning ran a few times, it was estimated that he was really tired, and later he went out to fight in Changchun and Taiyuan.

Every time Mu Feng was woken up, his mental condition became worse, his mood became more irritable, and the time he fell asleep became shorter and shorter.

At nine o'clock the next morning, Mu Feng woke up again from a short sleep, but this time it was not the sound of an alarm, but a strange feeling of wetness.

Mu Feng, who was in a trance, opened his eyes and found that it was Crimson who was licking his face very seriously.

"Hey......" Mu Feng, who was physically and mentally exhausted, was too lazy to complain, and reached out to pat Crimson's back, "Crimson, don't make trouble, you go to the restaurant to eat, I'll sleep for a while." ”

Crimson blinked a little suspiciously: "Commander...... You...... Under the weather? ”

"Hey!" Mu Feng was taken aback, "Crimson you...... Can you speak the full story? It seems that your cleanup yesterday was really effective, how do you feel physically? ”

Crimson reached out and touched her stomach: "Body...... Very comfortable......"

"It's good to be comfortable......" Mu Feng let out a long sigh of relief.

Although Crimson's thinking was still so simple and naïve, and her speech was still intermittent, she was able to fully express some meanings.

Mu Feng confirmed that Crimson was fine, and the drowsiness came again, and waved his hand weakly:

"Crimson, you go to the kitchen to eat first, and I'll sleep for a while."

"Crimson...... Accompany...... Commander...... Sleep ......"

After Crimson finished speaking, she got into the quilt, hugged Mu Feng's body with both arms, and pressed her chest directly on Mu Feng's chest.

Mu Feng felt the subtle touch in front of him, and shook his head helplessly: "Forget it, let's not sleep, let's go to the restaurant to eat something first......"
