Zhou Yun was very satisfied when he saw that the alien creatures in front of him were so knowledgeable, and looking at this situation, even the steps of the experiment could be omitted.

However, in order to be responsible for the customer, it is still necessary to test the power of the weapon, and only in this way can the customer be convinced.

Thinking of this, Zhou Yun explained his thoughts to these alien creatures, and let them see the power of the weapon, so that they could buy it with confidence.

Soon, they came to a clearing where they were ready to complete experiments on weapons.

With a "boom", a large pit appeared in the open space in front of him, and the ground shook.

Seeing the power of this small missile, the alien creatures around Zhou Yun gasped, this kind of destructive power was beyond their expectations, if they had this tone before, the casualties would not be so heavy.

After a while, Zhou Yun looked at a card in his hand, and was very satisfied, even if that race was just a small race, the funds paid made him very satisfied.

Five million blue crystal coins are naturally nothing for a race, but for Zhou Yun, this is already a huge amount of money.

With this fund, some of his plans can also be implemented, in this world, at the beginning, except for the meteorite steel suit, he can be said to have nothing, and now, with a huge amount of five million blue crystal coins, Zhou Yun feels that his life has reached the peak.

Now, he has a small black crystal in his hand, and this crystal of pure energy is the key to his next research.

The Ark reactor, developed using nuclear fusion technology, is a kind of energy conversion, and the violent reaction of hydrogen and helium atoms produces a huge amount of energy.

Without research, he still didn't know how much power this black crystal had, but he also knew in his heart that the energy contained in it should not be underestimated.

Nowadays, all kinds of tribes are fighting each other for this kind of thing.

He is just a hurried passer-by in this world, and naturally he doesn't care about what happens in this world.

The matter has come to an end, and he has to go about his own business, the instrument matter, and he is ready to solve it today, so that he will have something to do tomorrow.

Just got the five million blue crystal coins, he has confidence in his heart, money is not omnipotent, but no money is absolutely impossible, this wise saying, although the meaning expressed is very straightforward, but it is very in line with reality.

The instrument he wanted could be bought in the black market of the Floating City, but this time, the Moon Butterfly Clan was invaded by the Limo Clan, and the Floating City suffered serious damage, and the black market was naturally not spared.

This time, he mainly tried his luck, if the black market can conduct normal transactions, there is no need to go to other parties, on the contrary, he can only go to the city of chaos to try his luck, after all, he can study the instruments of black crystals, and all races attach more importance to it.

Blatantly buying, naturally, there is no path, but you can still get it by making dark transactions.

When Zhou Yun came to the entrance of the black market, he was dumbfounded, there was still the entrance of the black market, which was completely razed to the ground, and the previous battle, the destructive power was really too great, and many places were seriously damaged.

Faced with this situation, even if he didn't want to go to the City of Chaos, there was no way, in the Duchy of Kirtland, only the main industry of this city was the black industry, since this was the case, he naturally had to go.

Now, he is worth five million blue crystal coins, and when he goes to the city of chaos, he will naturally not use the previous flying machine, but lease a flying machine with better performance, and the previous one, he will naturally return it, but he signed a contract, if the aircraft is damaged, he will compensate up to 300,000 blue crystal coins.

A small transport aircraft with superior performance, it is different to pilot, and the speed is faster, this time, it was only used for three hours, and he came to the city of chaos, and this time, he found an abnormality.

There was an atmosphere of slaughter in the whole city, and it seemed that something had happened that he didn't know, but he came this time just to buy equipment, and he didn't provoke any race.

The destination this time is still the shop of the old man of the lizard tribe, Zhou Yun found that there are a lot of good things in the other party's shop, these instruments have been transformed by the old man of the lizard people, and the performance seems to be more superior, understanding this kind of thing, Zhou Yun sighed a little.

This old man of the lizard clan has an amazing ability in mechanical transformation, and Zhou Yun also has the intention of discussing with the other party, in order to learn the knowledge of machinery, he has put in a lot of hard work, and only he knows the sadness.

The old man of the lizard clan was also very surprised when he saw Zhou Yun, his small shop had not opened for two weeks, but he didn't expect that in just a few days, Zhou Yun would come twice, and it was difficult to remember.

When the other party heard what Zhou Yun needed, he was even more surprised, that instrument had been in his hands for a year, but no one cared, if it was not sold after a while, it was ready to be disposed of as waste.

Disassemble the entire instrument and get the parts inside to use to modify other instruments.

It is with this approach that he is able to improve his ability to modify his machinery, either by acquiring instruments that he can use or by improving his own skills, which is the best of both worlds.

With the money obtained from selling the equipment, the old man of the lizard tribe invested all of it in the recycling of waste equipment, and found good parts from a large number of dilapidated instruments, so as to carry out transformation, which is the work of the old man of the lizard tribe for a long time.

The master is in the people, for this sentence, he really understands, many people are not famous, but their ability is very strong.

There was business coming to the door, and the old man of the lizard tribe naturally had no reason to refuse, and pointed to an instrument next to him, and saw that the appearance of the instrument was almost the same as in the photo, Zhou Yun was relieved.

After paying 200,000 aquamarine coins, he left this place with the instrument, and after calculating it, he had already spent nearly 300,000 azurite coins, which was not a small number.

However, it is obviously nothing to consume this amount of money for scientific research, and the investment will definitely increase in the future, depending on what he can research.

For the direction of research, he has a general idea, energy is an indispensable thing for anything, if there is something small but full of energy, it will be absolutely crazy to be known by the scientific researchers of the earth planet.

Put the instrument in the laboratory, he started the research, with the research of his predecessors, in the initial stage, it was very smooth, and successfully stimulated the energy in the dark spirit crystal, but, in Zhou Yun's opinion, this method can only be regarded as the most primitive method, which will waste a lot of energy and cannot be used with maximum efficiency.
