Upon returning to base, White Steel was stunned to see two large circular gates towering over the cracks in the plane—if he remembered correctly, they didn't have before the vacation.

"You ...... The gate has already been built!? ”

Bai Gang asked, grabbing a researcher who was directing construction.

"Eighty-seven percent of the part is done, wait two more days, and in two days you can have the final inspection."

"Your progress...... It's too fast! ”

The man said disdainfully: "Please, it's not a whole casting, it's just a small part module built like a building block, and the accuracy requirements are even worse than during the First World War. Do you think it's hard to accomplish this with the world's second largest strength in China? It's not a problem to build at all, the problem is that it can't move without the help of the natives, and only God knows when Master Anu will come back! ”

In fact, Annu returned in a much shorter time than the people at the base had anticipated, due to their habit of ignoring the experimental mini-portals they had built earlier, from which Anu and his hired helpers had returned.

When Annu and the others emerged from the portal one by one, they startled the researchers who were conducting testing there, and the base immediately called an emergency meeting to reconsider the protective measures for the portal.

Afraid that the enemy would use the portal to carry out a surprise attack, the high-level officials directly designed the room where the portal was located as an "execution ground", with guns, bombs, mines and mines just the most basic, poison gas, flames, liquid nitrogen and even lasers!

However, the small portal that can only allow two people to pass through at most is of little significance even if it is used by the enemy, and what really frightens Commander Ren and them is the rift in their own plane!

If after the large portal is built, the natives like Anu and the others can use their own portals without knowing it...... It's better not to build it!

So less than ten minutes after the accident, Bai Gang was urged to inquire about the situation.

"Master Annu, I didn't expect you to come back so quickly, in fact, you don't need to work so hard, no matter what, your body is still important."

Seeing Annu, Bai Gang came up and greeted him warmly, at this time Annu was in high spirits, but the physical exhaustion was difficult to hide, and the whole person was like a ghost who hadn't come out of the Internet café for half a year (the author himself has really seen it!). It's been a bag for more than a year, and it's still a couple! Back then, it was strange, why didn't you get a computer yourself if you had such a package method as money! Later, I didn't see him for a while, and then I found out that the man had become a handyman in an Internet café...... ）。

Annu shook his head and said, "It's okay, don't look scary now, in fact, my body has never been so good!" Hahaha, thanks to you, with those Mithril you gave me, I said that I moved a reclusive master to heal my body, and I would have no problem living for another twenty or thirty years! Now I'm all thinking about the portal, and even if you let me sleep, I won't be able to sleep, so it's better to come over quickly. ”

"That's really congratulations, can these mages behind you introduce me to me?"

Annu patted his head and said apologetically: "I'm really sorry, I'm so excited to see the Earl, I forgot to introduce it, most of these are my friends in the Red Tower, and a few are space mages in the Colorless Tower, they are all experts in portals, more professional than us, and you can be foolproof with them." ”

Saying that, Anu introduced these mages to Bai Gang one by one, and after the introduction, Bai Gang invited them to rest and eat, and on the way, Bai Gang came to Annu's side and asked as he walked.

"Master Annu, aren't the portals a one-to-one correspondence? Why can you use our portal? ”

Anu smiled and said, "Count Bai, you take it for granted, if the portal can really only be used one by one, wouldn't those lively trading cities have to be portals everywhere?" In fact, as long as you can find the coordinates of the plane where the portal is located, you can complete the connection. ”

Bai Gang frowned: "In this way, doesn't it mean that if the enemy wants to use the large portal I built, it is okay to directly raid here, and even the Huaguo mainland on the other side of the door!?" ”

"In theory, it's possible, but in practice it's not." Anu explained, "Even if there are small commercial portals, other portals basically have defensive measures, you know, the human body is very fragile in the process of teleportation, and there is no room for resistance, even the space defense magic arranged by the apprentice can easily kill the master characters in the process of teleportation, so if you can't 100% guarantee the safety of the connected portal, no one will teleport at all, because that is simply suicide!" Not even a god-level powerhouse! ”

"Tsk, I see, but how do you locate the coordinates of the portal? Is it through a stable door or a portal? ”

The large portal is divided into two parts - a portal that tears through space and a door that expands the rift stabilization.

Anu replied: "The coordinates are determined when the portal tears through the space, so of course the positioning depends on the portal, as long as the portal is activated, there will be a unique spatial coordinate, and the stabilization gate only plays an auxiliary role, and it cannot be relied on to determine the coordinates." ”

Bai Gang thought for a moment and asked, "What if it's a rift that is temporarily opened when a summoner summons otherworldly creatures?" Can it be located? ”

Annu rolled her eyes and said, "Your mind is really jumping, Lord Earl. Attempts to locate the rift in order to reach the Atlas have failed, and it has been confirmed that the rift without a plane gate is unlocatable. ”

Hearing this, Bai Gang couldn't help but breathe a sigh of relief, that is to say, his own cracks are not locatable.

After chatting with Annu casually, Bai Gang found a reason to leave, and after confirming that Anu couldn't hear it, Bai Gang said: "You all heard what Anu said just now, right?" It's getting more and more troublesome. ”

Commander Ren, who was sitting in front of the screen, sighed and said, "The little things that are no problem for these aborigines are simply unsolvable problems for us...... Apprentice-level defensive magic can easily kill master-level masters, but the problem is that we don't even have apprentices here, let alone how to arrange defensive magic!

Fortunately, we already have a dimensional rift, so naturally we don't need a portal to tear the space, the portal is just a model and it is not activated at all, and it is impossible for others to exploit the loopholes. However, there is still a need to build some defenses around the plane gates, just in case.

In addition, I'm afraid that you will need to play a play for Master Annu and them, Major Bai. ”

"No problem."
