Mu Feng heard the knock on the door, and first glanced at Yuanwang No. 7 next to her, and made sure that she had returned to her normal posture before getting up to open the door, and at the same time wincing at the people outside.

Changchun, who was standing outside the door, instinctively stretched out his voice and shouted coquettishly:

"Commander...... Changchun wants to ......"

Changchun originally subconsciously hugged Mu Feng's waist, but when he saw Mu Feng's expression, he reacted at once, and looked inside:

"Ah...... Seventh sister is here......"

Changchun let out a low snort, immediately returned to a serious appearance, followed Mu Feng inside, and at the same time greeted Yuanwang No. 7:

"Seventh sister, you also came to play with the commander?"

Yuanwang No. 7 stood up and walked in front of Changchun, gently stroked Changchun's hair, pulled Changchun back to the living room, and let Changchun sit down next to him:

"The seventh sister came to find the commander, originally wanted the commander to study my hull and how to adjust it, but Changchun came over before we started."

Changchun did not doubt him, but said thoughtfully:

"Oh...... Indeed, Neptune, Sister Heping, and Sister Hulun have also changed their gas turbines, increased their speed, and installed some defensive weapons, and the hull of the Seventh Sister has not yet moved......"

Mu Feng looked at Yuanwang No. 7 with a little confusion:

"Seventh sister, are you serious?"

Yuanwang No. 7 had a natural expression:

"Of course I'm serious? Why, Commander, you don't want to help me? ”

Mu Feng hurriedly waved his hand and said:

"Of course not, if you need it, Seventh Sister, of course I have to go all out!"

Yuanwang No. 7 smiled and said:

"It's not too early, shall we start early?"

Mu Feng nodded a little subtly:

"Alright, let's go sit inside."

Mu Feng took Changchun's hand and took Yuanwang No. 7 into the bedroom together.

Yuanwang No. 7 took off his shoes, lay down on the Mufeng bed, looked at Mu Feng who was sitting on the edge of the bed, stretched out a finger and shook it gently, squinted his eyes and said:

"It's not allowed to do strange things to my sister while she's asleep, right? Changchun also helped supervise! ”

Changchun nodded seriously and agreed:

"Well, don't worry, Seventh Sister, I'll look at the commander."

Mu Feng's expression was a little embarrassed, and he didn't know if Yuanwang No. 7 was a joke, so he quickly changed the topic:

"Seventh sister, Neptune and Heping have brought some defensive weapons with them after their transformation, and you don't have any ship-borne weapons on you now, so you have to install some just in case, right?"

Yuanwang 7 thought for a moment:

"This world is really too dangerous, and it's definitely not okay to have no weapons on you, so it's good to be like them and pretend to be defensive.

"But don't pretend too much, think about it, I have eyes, a white coat, and a bazooka on my back, and I come here to do scientific research, it's not the same, right?"

Mu Feng nodded slightly, entered the system to find the hull of Yuanwang No. 7, and first observed it as a whole.

The Yuanwang 7 is 224.9 meters long, 27.2 meters wide, 44.2 meters high, and has a full load displacement of 27,000 tons.

As a scientific research ship, the personnel living on Yuanwang 7, in addition to sailors, are more scientific researchers related to aerospace surveying.

Therefore, the internal environment of the hull is much better than that of ordinary warships, and the seaworthiness is also very good, the freeboard is tall, and it can resist 12 typhoons.

Similarly, as a research vessel, he does not need to be very high, with a maximum speed of less than 20 knots.

But the endurance is very good, the range can reach 18,000 nautical miles, and the self-sustaining power is 100 days.

In fact, according to the type of work she does, this state is very suitable.

Mu Feng felt that Yuanwang No. 7 was just looking for a reason to stay.

But Mu Feng didn't say anything, and still managed to adjust her in a more suitable direction.

First of all, as a scientific research ship, the internal personnel space is relatively large, and there is a lot more space if it is slightly compressed.

The power system was then dismantled, six new gas turbines were installed, and an integrated power system was applied.

Six sets of gas turbines, providing a total of nearly 300,000 kilowatts of electricity output, of course, are not to be seen from afar, but mainly to simplify the ship's power supply system.

With these six sets of gas turbines and supporting generator sets, the power supply problems of various high-power scientific research equipment, observation, and communication antennas on her hull have been solved all at once.

At the same time, it also provides energy for various defensive weapons that he wants to add.

Mu Feng has always adhered to a concept, when I have a weapon, I can choose to use it or not, but if you don't have a weapon, then even if you want to use it, it will be useless.

Whether the weapon is used for defense or attack depends entirely on the mind of the person using it.

Only when we are strong can we be qualified to choose peace and to have compassion for others.

Mu Feng repaired the bridge of the Yuanwang 7 into a style similar to 055, installed various radars supporting the weapon system around and on the top, and installed the corresponding control system inside the bridge.

A twin 155-mm electromagnetic cannon is installed on the bow platform.

Around the top of the hull, a total of 4 sets of twin 76-mm electromagnetic guns, 4 sets of Hongqi-10 near-defense missiles, and 4 sets of 1130 close-defense systems are installed.

Eight sets of vertical launch units are arranged in the middle position for the installation of anti-aircraft and anti-ship missiles.

It seems that there are a lot of things, but in fact, the hull of the Yuanwang is very spacious, and it doesn't take up much space at all.

For example, you can fit four times more hanging hair, but you don't need that much.

In the end, Mu Feng looked at the abundant power system, but he couldn't help it, and built a small-scale scientific research program.

Adjust the shape of the Yuanwang's hull and strengthen the hull structure so that she can adapt to faster speeds.

Directly consume your own stored research points to complete, and directly adjust the application accordingly.

After all the adjustments were completed, Mu Feng asked the system to check to ensure that there were no problems, and finally confirmed the transformation plan, and Yuanwang 7 entered a dormant state.

Mu Feng exhaled and stood up, covered Yuanwang No. 7 with the quilt, took Changchun's hand and left the bedroom.

Close the bedroom door, go back to the living room, and sit down with Changchun in your arms.

Changchun sat on Mu Feng's lap and hooked Mu Feng's neck with both hands:

"Commander, how long will it take for the transformation of the seventh sister?"

Mu Feng lowered his head and kissed Changchun's lips lightly:

"It takes about an hour......

Changchun listened, rolled his eyes, propped up his body, and sat on Mu Feng's lap face to face:

"Shall we wait here then?"

Of course, Mu Feng didn't want to just wait, so he directly blocked Changchun's mouth, and the palm holding her waist slowly probed into her clothes.

The sofa said: I haven't seen any scenes, I'm used to it for a long time.

An hour later.

Yuanwang No. 7 slowly opened his eyes, looking at Mu Feng standing in front of his bed, Changchun holding his arm, a pair of watery eyes, as if he had just taken a bath, and his whole body exuded a lazy atmosphere.

Mu Feng was like a doctor, asking the patient with a serious face:

"Seventh sister, how do you feel?"

Yuanwang No. 7 stood up, stretched in front of the bed, frowned slightly, and said:

"My body is stronger, but you're stuffing too much stuffed into my body, is it really just a defensive weapon? I feel that the capital ships of ordinary countries can't beat me now! ”

Mu Feng said with a serious expression:

"Seventh sister, don't think about it too much, this is really just a defensive weapon, a defensive weapon......"
