Here in Fengtian City, Ouyang qianer is going to find Qin Ziyi in madiwen city through the transmission array of Fengtian city. Seeing that she is about to go to the transmission Hall of Fengtian City, she just sees Qin Ziyi coming out of the transmission hall and Tang Long is coming along.

Ouyang qian'er sees Qin Ziyi and Tang long, and quickly walks towards Qin Ziyi and Tang long.

As she walked along, she had already looked at Tang Long and said, "young master, we have completed our research on the fourth generation of rapid fortress, and the test flight has also been completed. Everything goes well."

"Really?" Tang Long was very happy to hear the news.

Now he needs to use the fourth generation of rapid fortress, the fourth generation of rapid fortress test flight completed, can directly solve his big problem.

Ouyang qian'er looked at Tang Long and then said, "last time you came over, we were already testing the fourth generation of rapid fortress. Now all kinds of tests have been completed successfully. There is no problem with everything. You can put it into use immediately!"

Tang Long said: "in this case, you will take me to see the fourth generation of rapid fortress."

"Good!" Ouyang qian'er agreed and led the way ahead.

Tang Long and Qin Ziyi, together with Ouyang qianer, soon arrived at a large and empty place behind Fengtian city.

Here, Tang Long has seen four swift fortresses and his former air fortress.

He asked Ouyang qian'er, "how is the transformation of the air fortress?"

Ouyang qian'er said: "the air fortress has been transformed and can be used, but as I said before, the air fortress is too big to transfer space!"

Tang Long said: "the air fortress can't transfer space, it doesn't matter, as long as it can be used as the transfer point of the rapid fortress, that's OK!"

Ouyang qian'er said: "we have made special mecha puppets to replace the flying pilots of the swift fortress and the flying pilots of the air fortress, which can save a lot of energy."

Tang Long agreed: "this can save a lot of energy."

Ouyang qian'er knew this arrangement in advance and supported it very much.

He looked at Ouyang qian'er and said, "first tell me how to drive this fourth generation fast fortress. I will use it now."

Ouyang qian'er takes out two scrolls, which are both inheritance scrolls.

She handed the inheritance scroll to Tang Long and said, "the driving methods of the fourth generation of rapid fortress, as well as some points to pay attention to, are recorded in the inheritance scroll. With the inheritance scroll, these methods can be easily learned."

Tang Long took over the scroll and directly put it into the sky sealing flag. Then he said, "I'm going to take all these fast fortresses away."

Ouyang qian'er said: "we are already studying the fifth generation of rapid fortress. However, we are only imagining that it is very difficult to make it successful, and we also need blood red crustaceans and other things."

Tang Long said: "this you slowly study, with the fourth generation of rapid fortress, has been able to solve many of our major problems."

With that, he went over and collected all the four fourth generation rapid fortresses into the sky sealing flag.

And he put the fortress in the sky flag.

At this point, he needs to use the fourth generation of rapid fortress, which is of great use.

Take away the rapid fortress, Tang Long and Qin Ziyi together, first went to the strange old man there to have a look, to see this period of time this strange old man again tossed out what strange things.

The strange old man was beside the chair where Mu Qingcheng sat last time. He was busy with his hands and feet. When he saw Tang Long coming, he looked at Tang Long and said, "Stinky boy, you're here just in time. I'm going to find you!"

Tang Long said curiously, "what do you want from me?"

Strange old head said: "I went to batian city two days ago. I heard that Qingcheng said that you had got a lot of supernatural animal essence blood before?"

Tang Long said: "indeed, I did get a lot of animal essence blood before, and those spirit animal essence blood are also the divine animal essence blood of dragon and Phoenix."

He got the blood essence of the gods and beasts in the strange space of Pamir city. After saving the dragon and Phoenix, he got them in another small space.

All those things are in his flag now.

Strange old head way: "you give those dragon and Phoenix blood essence to me some, I want the best."

Tang Long said curiously, "what do you want those for? Is it necessary to arrange attack array and so on? Or who are you going to help raise your blood? "

Strange old head way: "I want to use these things to do some try, have no use I don't know, you give me some is!"

Tang Long also didn't refuse, nodded and agreed.

He hoped that the old man would come up with something new.

He took out some of the blood essence of dragon and Phoenix, which were the best selected. The strange old man took away two bottles, which contained the blood essence of two ancient dragon and Phoenix.The strange old man carefully explored the two bottles of blood essence, and said with great satisfaction: "this is the top-level divine animal essence blood. With these two bottles of supernatural animal essence blood, my experiment should not have much problem."

Tang Long asked curiously, "what experiment doesn't have much problem?"

The strange old man curled his lips at Tang Long: "I tell you that you don't understand. Anyway, I take this thing to be of great use. Although this is only an attempt, and it is only an aid, but I believe that with this assistance, my experiment will surely succeed!"

Tang Long knew that the strange old man would not say more about this matter. Even if he asked the old man again, the old man would not say more, so he would not ask more.

He felt that when the old man came up with something strange, he would tell him.

Then he and Qin Ziyi stayed with the strange old man for a while, and then they left together. Then Tang Long and Qin Ziyi returned to madiwen city again.

Qin Ziyi looked at Tang Long and said, "husband, are you going to the enchanting land now?"

"Yes." Tang Long nodded: "I want to send the rapid fortress to the past. This fast fortress will play a very important role, because the blood demon world may be about to undergo great changes!"

Qin Ziyi took out four or five space rings and gave them to Tang Long: "this is a few space rings that I bought for a long time ago. There is a lot of space in these space rings. There is no problem to install one or two fast fortresses."

Hearing what Qin Ziyi said, Tang Long was extremely surprised.

If Qin Ziyi had not prepared in advance, he would have never thought of this crop.

He has a sky flag, but others don't.

Although Gongsun and Mo'er all have space rings, ordinary space rings can't hold such a big fast fortress. It must be a waste of time to find them temporarily.

For this reason, Qin Dazi doesn't have to prepare for this problem in advance.

He directly hugged Qin Ziyi, and then chewed on her face: "Ziyi, you are so careful. If it wasn't for you, it would be a thorny problem at the critical moment. You are really my good wife!"

Qin Ziyi was held tightly by Tang long, and her pretty face turned red slightly. She also followed Tang Long's embrace and said in a soft voice: "husband, I really hope that this catastrophe in the world can be ended earlier!"

Tang Long said: "I also hope that this catastrophe can end early." After a pause, he said: "as long as we all work together to solve the strongest people around the blood devil ancestor and the devil ancestor one by one, I won't have to take care of the later things. Then I will accompany you and go sightseeing every day!"

Qin Ziyi nodded with expectation. She hoped that the moment would come earlier.
