Tang Long knows that if this array is placed on a new generation of rapid fortress, the energy utilization rate of radiant energy crystal will be increased by at least 20 times!

The most important thing is, with this array, the energy can cycle all the time!

Although there will be some energy consumption in such recycling, but the consumption is very small, which can not only increase the flying speed of the rapid fortress by dozens of times, but also reduce the speed of energy consumption crystal stone by more than 100 times!

In this way, it not only greatly saves the use of energy spar, but also greatly improves the speed of the rapid fortress.

"If the second generation of rapid fortress comes out, it must be very strong!"

Tang long looked at the array in his hand. He was also very satisfied. He hurried out and found Ouyang qianer. He drew the array and made it into a scroll of inheritance. It took him half a day to explain the formation to Ouyang qian'er, who knew it.

After all this, it's late at night!

Ouyang qian'er and their new array are naturally very happy.

They have improved the second generation of rapid fortress in all aspects, and now they have this new array layout. Combined with their previous efforts, the second generation of rapid fortress, whether in terms of speed or comfort, is bound to have a major breakthrough!

Moreover, the defense of this new generation of rapid fortress can also be upgraded to a higher level.

The most important thing is, at this time, Ouyang qianer and they are already studying the third generation of rapid fortress!

At this time, they also had a bold innovation in this third generation of rapid fortress. This innovation is that they will arrange the blood red shell of hell devil spider in the rapid fortress!

They have a very bold idea!

The blood red crustaceans of hell demon spider contain powerful space power, and even contain some mysterious space runes and space rules.

They have a lot of blood red crustaceans, and can arrange a powerful space array on the rapid fortress.

This idea is completed. If the research is successful, it is likely that the rapid fortress can achieve space transfer!

Of course, this research is still in the initial state of imagination. There are still many problems in space power that need to be studied hard to seek breakthroughs. Obviously, there is still a long way to go to complete this step and it will take a long time.

However, if such a rapid fortress research is successful, it can make the rapid fortress become a terror existence that can transfer space everywhere in the air. It is not so powerful!

By then, the rapid fortress will be able to accomplish many things.

Ouyang qian'er and they told Tang long in detail about this idea.

After listening to their idea, Tang Long was shocked.

Tang Long thinks that these people are really rare talents in this respect. If the third generation of rapid fortress is successfully studied by them, it will be very useful for the future war between the blood god temple and the whole world!

"In this regard, you should study it with all your strength and strive for a breakthrough as soon as possible. If you need any support, please go to Ziyi!" Tang Long solemnly said: "this third generation of rapid fortress, we must study it out for me!"

"Good!"

Ouyang qian'er and they all agreed.

Seeing that Tang long supported their research, they were very happy, of course.

Tang Long and Ouyang qian'er talked about some other things about the rapid fortress and the air fortress. Then they followed Ouyang qianer and went to the warehouse to take a fast fortress.

This is, of course, the first generation of rapid fortress.

Although the second generation of rapid fortress has been basically successfully studied, the final dynamic array has just been developed.

Of course, after the research of this array is completed, all that remains is to build and assemble, which will be very fast.

Now there are many craftsmen in Tangmen. It takes not a long time to build a fast fortress.

According to Ouyang qianer's plan, the second generation of rapid fortress will be able to come out in less than half a year.

At that time, the third generation of rapid fortress should also be able to make a breakthrough in technology.

Tang Long took a swift fortress away. He left in a hurry and went to the Nine Emperor's palace. He went out from the Nine Emperor's palace, and then summoned the swift fortress from the sky sealing flag.

At this time, he also summoned the Xuanyuan sky array from the sky sealing flag.

And death and light come out together.

Tang long looked at the death demons and the Holy Light demons and said, "this fast fortress, you'd better learn how to open it, which is of great use to us in the future."

The death demon and the light demon both felt strange about the rapid fortress.

Xuanyuan sky array is going to open the fast fortress directly.

He has always been curious about the rapid fortress and has been studying it. Moreover, he also likes to open this fast fortress.

Tang Long went to sit down and rest.Holy light and death demons are curious to visit the rapid fortress. When they are finished, they will go to Xuanyuan sky array to learn how to open this fast fortress.

They are also interested in this strange big thing.

Time is in a hurry, the twinkling of an eye is already dawn.

Tang long had a good rest at this time, and he went to open a fast fortress.

Next, Tang Long has been in a hurry, day and night, the original need for four or five days of travel, three days he is finished, at this time, he has arrived at Leigu city.

Leigecheng is a big city.

Besides, it's a strange city.

In the middle of the city, there is a huge square, which is the size of fifty football fields!

on such a large square, a very mysterious array is arranged.

And in the middle of the array, a very high building was built. The building was as high as 1000 meters. It was a dark and strange iron tower. The iron tower was made of strange metal!

On the tower, there are all kinds of mysterious lightning runes.

Moreover, in the height of the whole city of thunder, one after another strange lightning, always thundering downward, but it is very strange that such a series of lightning thunderbolt down, but are all absorbed by the dark iron tower on the square of Leizhou City!

Because of the existence of the iron tower, the thunder city will not produce constant thunder and thunder. Under the protection of the tower, thunder and lightning will not cause any harm to the city.

In such an environment, high-altitude lightning constantly, but no sound can be heard below!

Moreover, there are many people living in this city!

Even this city, still very lively and prosperous!

This situation also makes Tang long very curious, such a place, there are so many people living, and it seems that these people actually live very well!

"The world is so big that there are so many strange things." Tang long thought secretly.

He was curious about the Dark Tower in the middle of the square.

Moreover, he was also curious about the strong defensive array that was arranged on the square.

This array obviously contains mysterious energy, which can absorb and condense the lightning power in all directions. The tower is even more mysterious. It can completely absorb the lightning power from all sides of the array!

"This tower absorbs the power of thunder and lightning all the year round. How strong is the power of thunder and lightning contained in it?"

"Or, the thunder and lightning force in the tower, can produce some kind of transformation?!

Tang long stood next to the square, feeling the powerful power of thunder and lightning in the sky, the power of absorbing the power of thunder and lightning, and the strength of the array covering the whole square. Looking at the mysterious tower in the array, he was full of curiosity.
