The thousand forged silver obtained from the old man is the size of a face plate, and you must know that under normal circumstances, there are already a lot of people who make a bowl the size of a bowl.

This time, even Chu Nan himself felt like he had made money, although he didn't know much about these things, he also knew that these rare metals were very few, but now that there were so many suddenly, it was definitely a big profit.

When Chu Nan and the others said goodbye, Aya was still a little incredulous, she never expected to come here once and get such a good thing, this is what she has been looking for.

Next, they didn't hang out, but chose to return, this time they came here, they did a lot of things, and their mood was relaxed, and they should also practice well.

On this continent, strength is strong, the strong are respected, only with strong enough strength can they run rampant in this world, otherwise it is absolutely difficult to survive.

The way back was very smooth, and I didn't encounter the existence of the evil mage, and of course it took several days.

This time, it took them half a month, which can be said to take a long time, but their mood was also released in this round trip, which was very comfortable.

Cultivation is about gradual progress, not in a hurry, only in this way can you grow rapidly, blindly immersed in hard practice. It is very likely to go crazy, after all, on this continent, things that go crazy happen from time to time.

Back at the academy, Chu Nan chose to retreat as soon as possible, this time he made a breakthrough in the realm on the way back and forth, which made him feel like he was leaping into the sea, and he wanted to absorb the experience on the way back and forth this time.

The retreat and cultivation were something he had thought about on the way back this time, and the battle with the evil mage had made him understand a lot, and the tricks with the master could make him understand his shortcomings, and there were some reasons why he needed to learn the magic he found in the skyscraper this time.

At this time, Chu Nan was in retreat, and the little black dog also chose to retreat, and as for Aya, she went to the inner courtyard. Who he wants to find and put back the harvest this time is an important material for research.

......

In a secret room, several people sat around a table.

These people were the Del and Nissan people that Chu Nan knew, and there was a design plan in front of them at this time.

"After my improvement in the past few days, the drawings have been determined, let's see if it's okay."

Leah said at this point.

She is the designer among several people, and she provides the drawings.

Everyone looked at each other, and then nodded in agreement.

If Chu Nan was here, he would definitely be shocked, because this so-called fighter jet is like a flying saucer, but this flying saucer is very terrifying, surrounded by a circle of shell holes, that is to say, when this thing is completely successfully studied, it will burst out with amazing combat effectiveness, at least he can be afraid of the enemy on all sides.

"Since it's okay, let's make sure we use this thing as a drawing."

After asking again, Leah nodded and said, these days, he has really struggled with folding paper, and it is really difficult to design.

Their requirements are very high, saying that they can fly, and they are not afraid of enemies on all sides, they can attack enemies in a circle, and they must take off and land at any time, and so on, which really makes Leah have a lot of headaches.

"Alright. Now that the drawings are here, the next thing we need to do is to study, Aya, you go ahead and procure the materials we need, Nissan. You're in charge of the command, Khruf, you're in charge of building, Leah, you're going to continue to improve this thing, and the Mu brothers and sisters, you're in charge of building the weapons that belong to this one, the ones that have to be high-performance, and I'm in charge of the energy composition of this thing. ”

Del was the leader of a group of several people, and arrangements were made at this time.

"Oh. By the way, and Chu Nan, Aya, you remember to ask him for money. ”

Del said hurriedly, as if he had thought of some crucial question.

If Chu Nan was here, he would probably roll his eyes a little, and he would be the one who paid for it.

However, he is happy to invest this money, after all, these things have been studied, but the existence of the sky, when the time comes, he will drive this thing around the continent, it is really very comfortable, it is much better than using the magic yuan himself, and it can be used as a good means of transportation.

Although the drawings designed by Leah are very small, but they are very comprehensive, this aircraft is very large, it can seat a total of six people, which is just limited to doing, and there is a bed in the middle, so that it can carry at least seven people, which is really a very good thing.

In fact, if this thing is placed here in Chu Nan, how many people are worth it, as long as his demon realm is big enough, it is not impossible to put down the entire Ionian people, but this is a bit far away, although the demon realm will grow larger according to the growth of his strength, but it is not so fast, it will take a long process.

......

At this time, Chu Nan was in retreat, and he didn't know what was happening.

Retreat, not only limited to cultivation, but also learning all kinds of magic, this retreat, he lasted a total of a month, when he came out, the little black dog they were still in retreat, this time out, they also have a lot of insights.

"Is there any information?"

Chu Nan was puzzled, because he found that the system actually had a message prompt.

"Congratulations to the host for installing 1,000 self-service vending machines."

These are words of congratulations, and there are many more below.

"Reward: [1] Host magic level +1

[2] Lottery chance +1

[3] Unlimited use of food robots [Requirements: Must build a food shop]"

After reading these rewards, Chu Nan himself was surprised, this time the rewards were really too rich, but he was a little puzzled, what does this so-called building a small food shop mean.

"A small food shop means having its own cabin, and then the food robots will replace the clerks, and they will be the salespeople inside."

The system seemed to know Chu Nan's doubts, and explained it to him, after listening, Chu Nan was really shocked, I have to say that the food robot does look like a human, if you don't know in advance or hear the food robot speak, it is really impossible to distinguish, in this way, it is definitely artificial intelligence to replace the operation of people.

This kind of black technology, Chu Nan was really shocked, you must know that even on his original planet, there is no such existence in that place of scientific and technological civilization, although there are robots, but there is no realistic enough to cook, and the existence that can open a store.

"Since Ionia, as an experimental base, already has self-service vending machines, the food robot experimental shop cannot be carried out in Ionia."

The voice of the system sounded again, making Chu Nan a little speechless, this is forcing himself to go out, and it is the kind that goes abroad.
