The current space wrap is not usable, because this space wrap is too fragile. It has a thin outer skin from the outside to the inside, so it must be strengthened and not damaged casually.

"No, why do you want to get the outer skin, I just need to get the inside right. ”

Suddenly, Chi Nan thought of a question, after all, what is really useful in each package is actually the buds inside. Thinking of this, Chi Nan simply dismantled the flower buds to transform and strengthen.

After a full day of adjustments, the final finished bud is manufactured. This bud was directly strengthened to the level of the silver peak by Chi Nan, but the space inside each bud was strengthened from half a cubic meter to one cubic meter.

As for the bud itself, the size is much smaller, a small waist bag, which can store a whole row of ten buds, and it does not take up space, and the original package can also hold other things.

Pond Nan has asked the Chamber of Commerce designers to start designing the shapes of various space wraps, and it will definitely be beautiful. And the leather on the outside, of course, should be used the best. The toughness of the bud itself is also the strength of a silver-level material. Even if it is hit by the fighting spirit of the Silver Warrior, it will be difficult to destroy it.

This space comes from the structure of the magic pattern, and even if the bud is destroyed, the contents will not be lost, but will fall out all at once. After all, this bud is not a space carved out from the outside world.

In the end, Chi Nan set up a lock opening authority on the flower bud, which can only be opened by the owner, which is equivalent to a password lock. As long as it is not destroyed, others will not be able to take out the contents of it.

"Very well, that's it, it looks like the men's wallets in the territory are going to break again. Thinking of the madness of those women on the earth for bags, Chi Nan showed a weird and sinister smile.

The parcel was put down, and Chi Nan continued his previous research. After a large number of experiments, it has been proved that all kinds of ground weapons are actually covered by airships. Airships are capable of replacing everything except ordinary weapons.

In the end, Chi Nan had no choice but to expand his ground weapons, and finally took shape into something that looked like a huge fortress. With such a large size, it is impossible to fly using the previous floating ball structure, unless Chi Nan evolves the floating ball. But it can't fly, and it's okay to float at close range on the ground.

The consumption may be quite small, but it can also be moved slowly. After all, this is a plant structure the size of a fortress, and the entire pond has made it more than 100 meters high and has a radius of more than 300 meters.

If this thing stops where it is, it's no different from a real fortress. Such a large thing, surrounded by thick dragon perch, this is a gold-level material, and it is extremely hard.

With such a large fortress, Chi Nan believes that even if a legendary-level master wants to destroy it, it will not be possible for a while.

There is also a layer of light pattern tree layer inside, which is the light pattern tree that has evolved to the gold level by Chinan, and the strength is very high.

In order to support such a large war fortress, there is not just one, but a full five, that Chi Nan has added to it. Spread out in five different corners while providing energy for the entire fortress.

The entire fortress is surrounded by weapons, and the wind cannons and ice cannons on the surface are densely packed, as long as the energy is not exhausted, no number of troops will be enough to die. On the surface of the city wall, a large number of vines were entangled, and these vines were covered with dense spikes.

The spikes are retractable, and when unfolded, they reach a level of two meters, enough to pierce a horse from head to tail. It is not a narcotic, but a special toxin that is a mixture of anesthetic and poison.

At the bottom of the floor, there is a large circle of flowers. This is no ordinary flower, this flower is capable of spitting out pollen when fighting, and this pollen has a very strong hallucinogenic effect. Inhale a little, even a silver-level master will be dizzy. The more you inhale, the more the gold master will definitely be affected.

At the top, there is a rooftop-like existence, densely packed with Bat missiles and hummingbird fighters. These weapons are capable of flying out of here.

In addition, there are quite a few pneumatic cannons on the upper level of this fortress. That's right, it's the pneumatic cannon that should have been eliminated, but this pneumatic cannon is not an ordinary cannonball, but another kind of explosive mushroom.

This explosive mushroom has also been evolved to the gold level by Chinan, but it is not shrinking because it is larger. So these barrels, too, have a diameter of three meters. When this big mushroom explodes, it is definitely no worse than the Bat missile in terms of unit power, and the most important thing is that it covers a very wide area, and it is not a small area of burning damage.

Speaking of which, without such a large barrel, it is impossible to carry such a large shell.

Inside the fortress, there are also a large number of production workshops, densely packed with various war weapons, and a formation of airships is stationed in it.

"No matter where you put this thing, it will be a war fortress in itself, and it will be called a war fortress in the future. Chi Nan was very satisfied with the four words of war fortress written on this thing.

"In terms of details, I'll leave it to others to study, anyway, this thing is by far the most powerful comprehensive combat weapon. On the ground, I don't think there's anything quite like this stuff yet. ”

"It's incomparable, this thing is a base in itself. Chi Nan, you said that it would be better if the base airship was directly integrated into the war fortress. "I didn't expect Sophia to be paying attention to this stuff as well.

Chi Nan was stunned for a moment, and then suddenly said: "Yes, why didn't I expect it, it's still our Sophia who is the smartest." ”

What I have always wanted to do is an invincible weapon of war on the bottom, balancing the balance of power between the bottom and the air. But I didn't expect that since I had already done this, why not go further.

If you directly integrate various base buildings into it, isn't this a complete active base? In this way, your self-sufficiency will be even stronger, and at most you will be surrounded by flowers everywhere you go, and there is nothing wrong with that. It doesn't matter whether it's a ground weapon or not, as long as the comprehensive capability is strong.

Thinking of this, Chi Nan was full of energy, directly controlled remotely, and began to pick and choose some suitable base buildings to integrate into this war fortress, which is really a perfect war weapon.

The only downside is that this thing moves too slowly. The speed is about the same as that of a normal Spider tank, and it is also very demanding on the ground. It seems that it's time to evolve those floaters.
