The results of the experiment made him very satisfied, this power has been at least doubled compared to the previous power, and on the battlefield, doubling the power of the weapon may turn the war around.

Next, he was going to go back to the floating city to have a good rest, all day, staying in the experiment, he also felt a little bored, the small missile had been successfully developed, and it was more powerful than expected, so he was ready to take a break.

However, when he returned to the Floating City, he found that the expressions on the faces of each of the inhabitants were very strange, and he did not know what was going on, but it would not be a good thing to think about it, otherwise the faces of the inhabitants would not be so ugly.

He didn't understand what was going on, so he didn't go back to the lab, but went to Yueyu's residence.

After entering, he found that the other party's face was very serious, and seeing this situation, Zhou Yun expressed his doubts.

"Yueyu, what the hell happened, your face was so serious."

At this time, Yueyu was suddenly awakened, she had been pondering just now, and Zhou Yun came to her side, but she didn't find it.

However, since Zhou Yun asked, she was not prepared to hide it.

After Yueyu's narration, Zhou Yun finally knew what was going on, it turned out that the floating city could float in the air, in addition to the material of the Moon Sky Stone, there was also the support of anti-gravity technology, and the operation of the anti-gravity system required a lot of energy.

The main source of energy is that kind of black crystal, but with the mining over the years, the storage of black crystals has been declining, according to the storage of black crystals of the Moon Butterfly Clan, it will not be long before it will be exhausted, and the floating city will not float in the air, becoming a thing of the past.

A month later, the city will fall to the ground and become a land city, for this situation, Zhou Yun has no waves in his heart, he has just come to this world, and he has no special feelings for the floating city.

Knowing the current situation in the Floating City, Zhou Yun also had a measure in his heart.

This world, facing a serious energy crisis, black crystals, pure energy crystals, like seedlings to grow, accelerate the growth of civilization, but this growth, the foundation is not solid, once the black crystals disappear from this world, the world's scientific and technological development will come to a standstill, and even regress.

This is the result of pulling seedlings to grow, since he learned about the development history of this world, he has understood this result in his heart, from the original coal energy directly to energy energy, this way of development, can not last long.

Whether he will stay in this world in a month is still an unknown question, and now thinking too much about it is useless.

After saying goodbye to Yueyu, Zhou Yun returned to his laboratory, and after resting for a while, he continued to work, he had already thought about the next plan, first make a fund, and then buy black crystals, and study it well, he felt that whether he could break through the bottleneck of technological development in the future was all on this black crystal.

The civilized races of this world have been studied for decades, but they have not gained the slightest, Zhou Yun knows that it is not that the races here are stupid, but that their horizons are limited, and the races here have not embarked on the road of nuclear fusion since they got this black crystal containing huge energy.

I don't have any experience at all.,It's a completely black research.,It's strange to be able to study it.。

After returning to the laboratory, Zhou Yun entered the network to browse the various things that happened at this moment, which has become his habit, and only by fully understanding the world and knowing the various things that have happened can he deduce the future development trend.

Suddenly, he was attracted by a piece of news, the big head clan and the multi-claw clan clashed because of a small black crystal mine, and the two clans started, but, when the battle was about to end, the lizard clan suddenly rushed out and reaped the fruits of victory.

Seeing this news, an idiom appeared in his heart, sandpiper and clam compete for fishermen and profits, and the current situation is how consistent with this idiom.

This is just news, but the information revealed in it makes him have to pay attention to it, and now that the situation has reached such a grim moment, he has no worries in his heart.

The easiest time to get rich is when there is a war, since ancient times, war money is the most profitable way to obtain capital, but this method has a high risk, without a certain strength, it is not to get rich, it is possible to lose your life.

However, Zhou Yun has a lot of confidence in his own strength, and if there is something that is not long-eyed to provoke him, he will let the other party know why the flowers are so red.

Yesterday, he didn't have such confidence, but after the success of today's experiment, his self-confidence will burst, and the previous weapon used one less one, so his confidence was not enough, but today he succeeded in creating that kind of small missile, that is, he doesn't have to worry about not being replenished after this weapon is used up.

Time passed slowly, it was already night, and at this time, the entire floating city was plunged into brilliant lights, and the nightlife had just begun.

In this world, the life of living beings is like a fat sheep to be slaughtered, if there is no strength, even freedom will become a luxury, along the way, he has seen too many such scenes, many intelligent races are locked in a cage, being treated as monkeys.

The law of survival of the law of the jungle is vividly embodied here, in the earth star, with the constraints of the law, ordinary people will at least have a relatively peaceful living environment.

Seeing this, he felt some sympathy in his heart, but it was only sympathy, he had no reason with these races, and he would not spend money for them.

After a while, Zhou Yun came to his destination, the Science and Technology Exhibition Center in the Floating City, where scientific researchers of many races gathered to show their scientific and technological achievements, and if they were valued, they might get an opportunity to go to the top.

The reason why he came here was to see what research results these so-called scientific researchers had, but when he turned around, he showed a look of disappointment, these research results are all based on black crystals, many of which are flashy and have no practical significance.

However, after a turn, he was not without gains, at least his understanding of black crystals rose another notch.

"Mr. Zhou Yun, why are you here?"

Suddenly, he heard a familiar voice, turned around, and sure enough, it was Yueyu, and there was a follower beside the other party.
