If he has nothing to do, he will find something to do for himself, and the last thing that Gray Dragon Castle lacks now is sweat and passion, Wang Wei plunged into the casino and played for several days. Tyra was amazed - the whole casino was his, and he could still play so energetically.

Late at night, Wang Wei fell asleep, and Luna opened her eyes and looked at the man who had put her upstairs in her arms. Today, Wang Wei is still wandering around the Gray Dragon Castle, as if he is full of inexhaustible strength, but everyone knows that he can't leave the Gray Dragon Castle at all, because only here, he is the safest, and the World Tree can isolate Wang Wei's breath in a large range. The only thing they need to watch out for is the next revenge from Dimogorgan.

The two-headed baboon has never been a generous person, and if he loses a head and will never come back, he will definitely not be generous and give it away so easily.

It is possible that Di Mo Gaogen will find Wang Wei along the head that has been sealed on Wang Wei's chest, although it is only a possibility, but it must not be guarded against.

Wang Wei knows about this, and the girls also know about it.

This is also the reason why Wang Wei never leaves the Gray Dragon Castle, he is the kind of person who will never make trouble for his own people.

But now Luna finds that she is becoming more and more unable to see through her lover, she has lost the contract link, and it seems that the two have lost their previous tacit understanding, to be precise, it seems that Wang Wei has become a little out of touch in the recent period, and it seems that it does not match his original personality. But it's not really disconnected, because he's who he is, and Luna knows that the man hasn't changed.

What's changed?

Luna reaches out and gently strokes the other's face.

This face has always been tense, he is always busy, busy with one thing, and then start busy with another, it seems that he is always idle, he is even busier than the emperor. But it was only after he was injured that he gradually relaxed, his face was full of sincere smiles, and he felt happy from the bottom of his heart.

It was a sense of relief.

Luna's hand gently rubbed Wang Wei's cheek, if it was before, I'm afraid the other party would have woken up a long time ago, and then pounced on him with a wicked smile. But now he is really asleep, and there is hardly anything to disturb him.

This man has lifted all guards.

Early in the morning, when I woke up, Wang Wei was lying in bed with Luna in her arms, and Elidan went out to exercise early. The simple-minded Derpy Gua thought very simply, only when she is stronger can she better protect Wang Wei.

Luna looked at the man who had barely changed from his sleeping position, gently removing his large hand from her chest, and knew that all she had to do was look at him and support him, and that was all that mattered.

After being held back for too long, a certain man finally held back his anger. He couldn't leave the Grey Dragon Castle, so he simply began to sit there in a daze, but he wasn't in a daze without doubt, he was thinking about a lot of things.

Of course, at least on the surface, it does.

"I don't have any strength, don't I have any brains?"

Wang Wei, who had been thinking about it for two whole days, finally expressed the above opinions.

All the time, Wang Wei has been thinking about how to regain his strength, although it is a pity that the power is lost, but he does not have any reluctant emotions in it, as if he has long been unwilling to have these powers. He began to think about how to gain new power when he didn't have it, and this power was simple, that is, the knowledge he had, which was different from the previous knowledge.

Wang Wei suddenly remembered that since he came to this world, Wang Wei had always fixed his power on something unique to this world, that is, the elements.

In the past, there was also something that supported the world, and that thing was called mechanics.

It can be said that Wang Wei's previous world was built on mechanics, and people believed that relying on their quantum mechanics could solve all the mysteries of the universe. After encountering the elements, Wang Wei immediately realized that quantum mechanics actually worked, after all, these elements did not look any different from the elements.

So, since the elements that Wang Wei wants can't be used now, it's always okay to use the previous knowledge, right?

It's just that this kind of thing is easier said than done.

Wang Wei is not a research scholar, and his greatest advantage is that he has an excellent memory, but memory may not be able to be transformed into practical things. After holding back for a few days, Wang Wei finally discovered that those things in the previous world were on the verge of elimination in this world. There is no doubt that airplanes, tanks, and cannons are more than the ubiquitous elements of this world, but some ideas are not problematic.

A Mithril Elf can only control two small crystal-burning cannons, and once they are asked to control the large crystal-burning cannons, the magic net in the puppet will be unable to support it due to energy overrun. But what if a new tank is made?

The only requirement for a tank in Earth combat is to provide a strong firepower output while resisting an attack. And now, Wang Wei has lost his strength, but he has a magic net, and the magic net is the premise of the output of all attack power.

To build a tank, you must build a tank. This is Wang Wei's plan.

Earlier, a number of tanks appeared on the mainland. But these bulky devices really can't afford the value of their price, so after a few years, this kind of thing is gradually phased out. However, what Wang Wei wants to do is different from theirs.

Unmanned is an idea, and many people in the world have this plan in the past, and if the tank really reaches unmanned, it will at least save a lot of resources.

Wang Wei's plan was simple, he wanted to build a tank force, a tank force that would not be easily destroyed.

However, this plan was rejected by the Shadow Girl almost instantly.

"No, your plan requires the use of a levitation circle, unless you can lay a magic net on every corner of the continent, the magic consumption alone is enough to make you cry to death!"

The shadow girl didn't give Wang Wei any face at all, she was telling the truth. The levitation circle is very simple within the range of the magic net, but once it leaves the range of the magic net, the consumption of this thing will really make everyone jaw-dropping.

"However, it's not without opportunities, in the past, in Evanses, the technology of the puppets was not too advanced, although their energy technology was very advanced, but now our puppet technology is very advanced, and we now have the magic technology of response, so maybe we can get something very good. ”

The size of a puppet is inversely proportional to its ability to move, and is a linear process with energy consumption. Except for Verne, who has now made large puppets suitable for the use of mountain giants, but Wang Wei does not need their help, with the small puppet technology, and with the help of small sesame, the Phantom Girls can easily design large mechanism puppets. Since Wang Wei named an unmanned model that could install a large crystal-burning cannon, the Phantom Girls simply turned the power furnace in the center into a huge device to meet the needs of firepower output.

The result of the design was very unsatisfactory, in order to balance the power and energy output, the entire puppet almost became deformed, after all, Wang Wei needed a cannon that could move on its own, and it also had to meet sufficient defense, and the heavy body made the ordinary two-legged puppet move extremely slowly.

In the end, Wang Wei, who had changed back and forth, still threw away one of the functions of the tank.

Armor.

The final result of the discussion made Wang Wei very frustrated, the energy usage rate in this world is very low, especially for the elements, a bulky tank needs to consume less energy than directly to build a few large bombs and drop them with a lion dragon.

Therefore, Wang Wei simply hit the idea on those scorpions.

The seventh-order scorpion has reached a rather gorgeous point in size, and its power is even more incredible. Their bodies are strong enough to bear a considerable amount of weight, compared to the recoil of a cannon.

What's more, the tail behind the scorpion has become three.

The scorpion's strength follows the size of the magic crystals in its body, and the scorpion's tail has become three, indicating that the magic crystals in his body have also become three, and his tail is a natural energy energy output unit. Instead of thinking about the construction of a tank, it is better to mount a powerful gun directly on his back. Anyway, the scorpion can control the return to the contract space by itself, and the loss can be controlled in a reasonable place. It also saves a lot of resources.

This idea was supported by Wang Wei, and the only drawback of the large crystal-burning cannon was its high recoil and unsustainable energy output. Wang Wei has solved the need for magic crystals in the bottomless pit of the Burning Crystal Cannon, and now he only needs to place the energy device and cannon on his body, and then use their tail control to complete the shooting.

The final shape was the same three-series cannon as the aircraft carrier designed by Wang Wei, but it was much smaller than the super-large caliber thing. The scorpion can extend its tail behind the cannon for fire control.

Compared to the puppets used by the elves, this cannon is very powerful, and the range of firepower is very large, but the elves are pursuing a large damage output for a few targets. After a simple test, the scorpions should be able to operate these things with ease. A lot of equipment is saved and used in the energy system.

Wang Wei has been holding back in the Gray Dragon Fort for three months.

In three months, his face was completely white, and he successfully turned into a strengthened version of the little white face - the big white face.
