Tang Long said curiously: "What special purpose is you to make such a puppet beast?"

Luo Yuhan said: "After this puppet beast is successfully made, we only need to give this puppet beast a fixed ability to move. We can control it with our soul to allow this puppet beast to open a rapid fortress, which is much more convenient and safer."

After a pause, Luo Yuhan explained: "Using this kind of puppet beast to open a fast fortress, the puppet beast is tireless and can save manpower. We only need to integrate a soul command into it, and we can control the puppet beast with our minds. In this way, it will be very easy to open a fast fortress. Otherwise, it will take at least two people to open a fast fortress!"

After hearing Luo Yuhan's idea, Tang Long immediately agreed and said, "You are really amazing. You actually thought of such a way to control the rapid fortress. This way, you don't have to waste manpower when opening the rapid fortress, and it can better ensure the stability of the rapid fortress."

Luo Yuhan said: "This is mainly the idea that the old man came up with. He knew too many techniques. In addition, he said that you gave him a very complex formation drawing before. Based on that formation, he integrated some of the techniques and formations he knew, so that this puppet beast of the puppet mecha could make the rapid fortress control the easiest way."

After hearing Luo Yuhan's words, Tang Long looked forward to the completion of the manufacturing of the fourth-generation rapid fortress.

He knew that once this fourth-generation rapid fortress was built, it would definitely play a great role in the subsequent battle against the demon clan and the blood demon clan.

Not to mention anything else, at least it can play a big role when mobilizing people.

Although he could quickly reach Ye Qingling and the others with the Huixin Sect, this was limited to Ye Qingling and the others, and others would not do it.

But with this fourth-generation rapid fortress, when encountering major dangers, everyone will have the opportunity to quickly transfer.

You know, both the demon clan and the blood demon clan have very powerful existences.

The most important thing is that these guys use any means to do things. At some point, these guys are likely to use extreme means to threaten them. If Tang Long has a rapid fortress, in some cases, he can solve some extreme problems! So Tang Long thinks that this fourth-generation rapid fortress is definitely very important to them.

If Tang Long and the others have this rapid fortress, they can quickly gather everyone, or allow everyone to move away quickly in times of danger, so that they can better ensure everyone's safety.

Tang Long looked at Luo Yuhan and asked, "How long does it take for the rapid fortress to transfer space to complete this transfer?"

Luo Yuhan said: "It only takes twenty seconds!"

"Twenty seconds, very good!"

When Tang Long got this answer, he felt more and more satisfied.

He asked, “How long will it take for the fourth generation of the rapid fortress to be put into use?”

Luo Yuhan said: "We guess it will take less than two months. In two months, we can build at least two rapid fortresses that can transfer space!"

As he said that, he paused and said, "However, because the blood-red carapace of the Hell Demon Spider is limited, and those blood-red turtle shells have been used a lot, so at most we can create five such rapid fortresses that can transfer space!"

Tang Long was a little surprised: "I brought so many blood-red turtle shells before, but I could only make five fourth-generation rapid fortresses?"

Luo Yuhan said: "This is impossible. Although there are indeed many blood-red turtle carapaces, they have to be processed before they can be used. There are very few parts that can be used. This is a problem that the old man only solved after researching for a long time. As for the blood-red turtle carapaces of the hell spiders, there are not many left before, and they also need to be specially modified to use them, so the consumption is very large!"

Tang Long asked: "How many people can a fourth-generation rapid fortress accommodate?"

Luo Yuhan said: "Can accommodate fifty people."

"Fifty people, this is not a small number!"

Tang Long thought for a while and asked again: "How is the defense of the fourth generation of rapid fortress?"

Luo Yuhan said: "There is no problem with defense, because we have used all the materials of the blood-red turtle shells. We have also laid a defensive barrier outside the fourth-generation rapid fortress. Even if it is a strong Earth Ancestor, the fourth-generation rapid fortress will not be bombarded and broken by a few attacks."

He paused and continued: "The most important thing is that we have arranged a formation connection between the defensive barriers inside and outside the rapid fortress. The warriors in the rapid fortress can use the formation to integrate their vitality into the defensive barriers of the rapid fortress, so that the defense power of the rapid fortress can be enhanced!"

Tang Long said: "How is the flight speed of the fourth-generation rapid fortress?"

Luo Yuhan said: "The flight speed of the fourth-generation rapid fortress is ten times faster than that of the third-generation rapid fortress, exceeding the flight speed of the strongest Earth Ancestral powerhouse."

“This is not bad.”

Tang Long is quite satisfied with the fourth-generation rapid fortress. Such defense and flight speed can also be used to transfer space. Such rapid fortress is already quite good.

Luo Yuhan added at this time: "In addition, we are also modifying the air fortress, and also arranged teleportation arrays and space arrays in the air fortress. Although this air fortress cannot be transferred in space because it is too large, it can allow other rapid fortresses to quickly transfer around the air fortress, and the defense of the air fortress has also been enhanced to the strongest by us."

Tang Long said with satisfaction: "The fortress in the sky is indeed very large, and it is already very good to be modified and strengthened by you."

He paused and asked, "Where is the old man? I'll go see him."

Luo Yuhan said: "He is here, and there is his special laboratory."

He paused and said, "His laboratory is strange and he has arranged a lot of messy things, which we can't understand."

Tang Long said: "The strange old man seems to have many secrets hidden in his body. When I saved him, he was being investigated by the people of the Blood Temple. The people of the Blood Temple obviously attach great importance to the secrets that exist on him!"

Luo Yuhan said curiously: "What's the secret about him?"

"I have no idea."

Tang Long said: "I think the secret in him should be his achievements in the artifact master. He is indeed much better than ordinary people in refining weapons. If the people in the Blood Temple know his abilities in this area, of course they will do whatever they can to get him."

Luo Yuhan nodded: "He is indeed very powerful in refining weapons. My brother and sister used to think that we are already very good in this regard. We are already proud of being able to create that kind of monster mecha. However, after we met him, we realized that we are far worse than him in this regard!"

Tang Long said: "Okay, keep busy with yours, I'll go and see that weird old man."

As he said that, he turned around and left with Qin Ziyi and Xiao Que'er.

Soon they arrived at the place where the strange old man was.

This is a big and large laboratory, ten times larger than the laboratory where Luo Yuhan was before. It is filled with all kinds of messy things and a lot of materials left over from the blood-red turtle shell.

The remaining materials have divided blood-red runes on them, and they are all sorted out and placed in some places.

Obviously, the old man has to use these materials for research.

The strange old man looked at Tang Long and smiled and said, "You must have seen the fourth generation of express fortress, how about it?

We made it pretty well, right?”

"Not bad, really good."

Tang Longdao had already walked to the side of a very strange big jar here.

This jar is completely transparent. Thousands of metal lines made of various metals are connected around the jar. An extremely powerful energy-gathering array is arranged outside the line, and a very powerful lightning array! Thunder and lightning flashes in the jar, and there is a fist-sized lightning ball in the center, and there are countless dense and extremely subtle patterns in the light ball.
