When Dragon King and Carl talked about Jianmu's clan, the results of the detection of the branches of the Evolution Tree have come out.

Carl looked at the test result report and showed a look of surprise in his eyes: "Dragon King, this plant can indeed be used as a substitute for black gold."

"May I?"

"It is true. Although its hardness is slightly worse than that of black gold, it has good ductility and compressive resistance. It is enough to use it to make a portal."

"So, can the portal be built?"

Carl asked carefully: "Dare you ask the Dragon King, are there many such plants?"

"It's okay."

Carl was silent for a moment and said in a sincere tone: "Your Excellency Dragon King, no matter how many plants there are, from my personal perspective, I would like to advise the Dragon King that it is best not to let other civilizations know that Dawei has such materials comparable to black gold. Otherwise, this is likely to attract covetousness, even if it is the self-universe, it is not actually peaceful."

The Dragon King glanced at Carl and smiled and said, "Well, don't worry, and in fact, there are not many such plants. After building the portal, there are probably no more left."

Carl nodded and changed the subject: "What about energy? Dragon King is ready to use black hole energy to promote it?"

"Well, just use black hole energy, it is more convenient to create black holes."

"Okay, Dragon King prepares the materials, and then we go to another planet to make portals."

The reason why we don’t create portals in Dawei is because the project of making portals is huge, and black holes will bring powerful radiation. The Dragon King is fine, but ordinary people obviously cannot withstand the radiation of black holes. It is much safer to create portals in aliens.

Carl came to Dawei this time and also brought some engineering and scientific researchers. These people all have complete technology to manufacture portals. As long as the materials are sufficient, nothing will be a problem.

Under the guidance of Carl and the engineering researchers, the Dragon King first captured hundreds of barren planets, and then fused them together to form a super huge planet.

This super huge planet is about three times the size of the sun, its density is about fifteen times that of the earth, and its weight is about two hundred and three times that of the earth. This planet will become the carrier of the portal.

The Dragon King took the initiative to create this planet because it was so fast. If Karl and others were asked to do it, it would probably take several years for this job alone. The Dragon King didn't want to wait that long.

This planet was named the portal star by the Dragon King because it will become the portal between the great power and the universe in the future.

After finishing the portal star, the Dragon King took out some trunks of evolution trees and then penetrated these trunks into the interior of the planet in a certain direction, with the focus on the underground where the portal will be built in the future.

Because the portal is quite heavy, the foundation must be laid, otherwise it will be funny if the portal collapses or fails to enter the stone.

After the portal frame is built, dig out the star body below and build out the energy generator of the portal.

Next is the Dragon King who created a black hole. The black holes created are captured by a large black hole capturer and then sent into the energy generator. When the number of black holes is sufficient, the energy generator can generate enough energy to promote the operation of the portal.

During the entire production process, the Dragon King made considerable efforts, more than 80% of them were done by the Dragon King himself, and the remaining 20% ​​were completed by Carl and those engineering researchers.

The overall structure of this super-large portal is more than 100,000 meters high and has a width of about 30,000 meters. Its weight is about 71 times that of the earth. If the Dragon King had not specially created the portal star and placed it on an ordinary planet, such a weight would be enough to suppress that kind of ordinary planet to explode.

Connect the coordinates of the one, two, one star ring portal, and then turn on the energy generator. The majestic energy begins to appear. A slight tremor comes from the portal frame, and then it becomes stable. Finally, a silver-gray space vortex is formed in the middle of the portal.

"Successful." Carl breathed a sigh of relief, "With this portal, Dawei and the One-Two-One-One-One-One-One-One-One-One-One-One-One-One-One-One-One-One-One-One-One-One-One-One-One-One-One-One-One-One-One-One-One-One

The Dragon King also nodded happily.

It is worth mentioning that because this star ring portal is relatively huge, the tearing power during teleportation is also very terrifying. Therefore, the requirements for teleporting items are relatively high, and ordinary spacecraft cannot pass through this portal at all.

If it is a direct teleportation of creatures, the physical requirements for the creatures are also very high. Perhaps only strong people above the Star Sea level can withstand this kind of power. If they are below the Star Sea level, they will be avoided and will be torn apart by space power.

Building a portal is only the first step, and the next step is to build a defense system around the portal.

In fact, the structure of the portal is very stable and will not be damaged easily. But even so, the defense of the portal is the top priority of all civilizations. After all, there are still many weapons in the universe that can destroy the portal, and the role of the portal is too huge, which can be said to be a battle between military strategists. Now, the first thing to destroy and protect in various civilizations in the universe is the portal.

Carl has prepared several plans for the Dragon King, all of which are relatively mature defense systems. These defense systems have been verified countless times by the Lion Heart Empire. Although I dare not say that they are foolproof, they are indeed very effective.

The Dragon King chose the most widely used defense system, called the multi-satellite arch defense system.

This multi-satellite defense system is to set up some satellite planets around the portal star and guard them around the portal star. In this way, once foreign enemies invade, they must first pass the satellite planet level to gain time to protect the safety of the portal.

To this end, the Dragon King imitated the structure of the solar system and created eight satellite planets around the portal star, allowing these eight satellite planets to revolve clockwise with the portal star as the center, and set up a military base on these eight satellite planets, which sent troops to settle in.

But this is not enough. In addition to the eight satellite planets, the Dragon King has traveled thousands of miles to capture hundreds of planets from distant star fields, making them secondary satellite planets of portal stars. These secondary satellite planets do not need to set up military bases, but they have to arrange some unmanned detection equipment and control them with intelligent systems.

Finally, invisible dark thunders are required to lay out the star fields around the portal star. The location of these invisible dark thunders will change every few days or weeks. In short, everything is to protect the safety of the portal and not be destroyed immediately.
