The journey at sea was a bit boring, but it also meant that Green had more time to do the things he needed to do, such as studying the gravity ring.

The gravity ring is a large metal ring structure engraved with a magic array, and although this metal ring structure may not seem difficult to make, the material science principles contained in it are difficult to see from the drawings - quenching? Carburizing? What is the proportion of metals such as gold, silver, copper, iron, etc. in the material? None of this is shown on the drawings.

According to the drawings, the gravity ring can be made, but it is difficult to guarantee whether it will work properly. Of course, if you have a lot of money, regardless of the magic guide part is all Mithril on the magic part of the magic part of the magic resistance, all the magic iron is on the magic resistance part, and all the anti-pressure part is made of pure gold, then the gravity ring made should be able to function normally even if there is a slight problem - this is like making a cannon out of brass or bronze when the steel smelting technology is not up to par, which is a typical example of "not enough technology, equipment to make up".

Although the method of "not enough technology, equipment to make up" can solve technical problems, this method is too expensive!

Fifty tons of pure gold! That's not some kind of broken metal! It's pure gold!

Although Green is very rich, it is compared with "people", and this kind of precious metal consumption calculated by the ton is a bit unbearable even if the power of the whole country is too much!

If you don't have enough money, then what can you do?

Of course, only technology can make it up!

……

And then it all turned out to be back to square one. Rather than buying fifty tons of adamantite, Green felt that it was easier to climb the tech tree.

"It's not easy to get the key technology, but it's stuck in material science." Green sighed, put down the information in his hand, touched his chin, and looked up at the dark sea outside the window, "Materials science...... Sure enough, I still have to find a way to kidnap a dwarf who is good at metal smelting technology. ”

Master Harry is good at pharmacy, Miss Beth is good at magic technology, and the experts in materials science are still in a state of "waiting to be recruited" - the workshop in the territory can only produce "gray quality" civilian equipment at present, and Green's original idea of mass-producing magic rifles has had to be put on hold due to material factors.

"It's almost time to rest." Green rubbed his forehead, put away the papers on the table, and put them in the folder.

Green stood up from his desk and stretched.

"Da Mei, get me some hot water!" Green shouted out the door.

"Yes, master~" The voice of the succubus royal sister came from outside the door.

It didn't take long for the succubus to enter the room carrying a bucket of hot water.

"Master, hot water."

"Huh?" Green looked at the succubus in front of him and couldn't help frowning, "What's going on with your boobs?" ”

The succubus has two large water bags on his chest! Since the proportions of the breasts are really weird, it looks a little disgusting.

Feeling Green's disgust, the succubus's expression stiffened a little: "No, nothing." Maybe it's because of the repulsion of the plane. ”

"Tsk!" Green instantly lost all his desires, "Forget it, put the hot water down, you can go." ”

"Yes, yes." The succubus hurriedly put down the bucket full of hot water and left the room.

After leaving the room, the succubus palpitated and touched the pair of eldest daughters on his chest. Am I mistaken? Isn't bigger boobs better?

Bewildered, the succubus stood outside the door of Green's room, thinking.

At this moment, Succubus Lori pushed a food cart and walked over.

"Hey~ little one, you're not in the kitchen, what are you doing here?" The succubus royal sister did not hesitate to block the way of little Lori.

As a succubus with sound strength, Mei Mena looked down on the weak chicken succubus in front of her from the bottom of her heart!

"Get out of the way, I'm here to deliver supper to my master." Little Lori also has no good feelings for the compatriots in front of her.。

The so-called same-sex expulsion, unless the relationship between superiors and subordinates is determined, the relationship between demons has always been bad - succubi are no exception.

"Hey~ little guy, you'd better be honest and don't spoil my business! Otherwise, I wouldn't mind using the abyss way to make you feel the demonic passion! The succubus royal sister stared at the succubus Lori in front of her with a wary face.

"Bad for you?" Succubus Lori sneered, "Don't you think you have a chance to charm your master?" Stop dreaming, that's impossible. You're a piece of trash in the eyes of your owner! ”

"Trash?" Memena's expression changed slightly, and she suddenly remembered the way Green looked at her just now. At that time, Green's eyes made Memena feel a little scared......

"That's right, in the eyes of the master, you are a big piece of garbage!" Succubus Lori stimulates the people in front of her with vicious language.

"Nope! I'm pretty sure the host was interested in my boobs! ”

"Boobs?" Succubus Lori puffed up her chest, "You mean the two lumps in front of me?" Just two lumps of fat, but also want to charm the owner? Are you thinking too stupid about your master? ”

Memena looked at each other's chests, then at her own, and thought for a moment.

"Hey! I see what the problem is! Memena suddenly laughed, "That's right. It's true that two lumps of breast (harmony) room are not enough to make such a strong man fall, but I can tempt him with more milk (harmony) rooms! ”

That's right, since a pair of Nunako can't conquer the enemy, let's have a few more!

Succubus Lori's expression changed slightly: "You can't do this!" ”

"Hahaha! Are you scared? Memena laughed wildly, "Wait, I'll use my boobs to make the master fall in love with me completely!" ”

Succubus Lori's face became very bad. Looking at the expression of the little Lori, Mei Mena's mood became more and more happy!

"It's noisy!"

With Green's voice, the room door "Bang!" The ground suddenly opened, and a black ball flew out of the room and smashed directly into the succubus who was laughing maniacally.

"Ah!!h The succubus lady fell directly to the ground and screamed in pain.

Greene: "Go back and copy the maid's code a hundred times!" ”

"Yes, yes, master." The succubus sister knelt on the ground, trembling.

Although she pretended to be scared on the surface, Memena did not have the slightest fear in her heart. Damn it! Wait for me, tomorrow I will show you the power of the Nunoko Ocean! After I use Nunoko Ocean to make you fall, see how I clean you up!

Succubi are born with the ability to transform, and this "transformation" is not just a superficial "transformation", but can change from the root! They can be transformed into any image that suits the tastes of the person they are charmed with. A few more pairs of female nakos are really not a problem for succubi.
