The changes in the flag wheel excited the boys. Under the guidance of the flag wheel, the boys quickly found the final direction of the flag wheel.

"That's it?"

After several peaks up and down, several boys came to a snowy plain. The terrain was quite flat and wide. Several mountains around the area surrounded this area to form a basin-like area. In this area, the flag wheels completely lost their directional function, and no matter how they shake, they had no particularity like ordinary flag wheels.

"Buddy, how do you get inside?" Fortunately, the boys have had some experience with this kind of thing, and they know that under this normal state, there must be unimaginable ways to get inside.

"I don't know! I have only observed those guys entering the inside directly, and I have never seen humans entering the inside with keys." Budi spread his paws and answered helplessly.

"Damn it! You are such a irresponsible person as an interstellar observer!" Several middle fingers were towering towards it. Although everyone knows that Budi often uses automatic recording equipment, and only things that make it interested will make it pay attention to it at all times. Moreover, at that time, its strength was strong, so naturally it would not pay too much attention to these alien similarities with much lower civilization levels than it.

"Since that's the case, everyone will go to find the abnormalities around them." Duan Guoyu saw that there was no other way, so he could only let everyone scatter and find the most primitive stupid method. Everyone knew that there was no other way, so they didn't say anything else to scatter.

“There’s something here!”

Don’t say it, this stupid method really works. More than half an hour later, good news came from Zhen Lan.

"It seems that someone has come before us..."

What came into view was a place on the south side. A pile of messy snow piles mixed with gravel and sand from the mountain were piled up beside it. The excavated places and snow piles were covered with a layer of fresh snow, so that you could not find any abnormalities here without entering. It was just that people were alert that after searching for the areas near these snow piles, they found that some engineer shovels, damaged tents, small wine pots, cigarette boxes and other items were discarded next to them.

"Budy. Did the guy sent by the beard find this?"

After a little checking the discards, Duan Guoyu and his team found that these things had been discarded here for quite a while, observing the appearance and quality of the engineer shovels and the tight and solid workmanship of the damaged tents. The boys concluded that these things should be produced by the country of beards, and only people from that country would be famous for their meticulous work and style.

"I didn't know that he sent two search teams. The first one was five scientists, and a few years later when the second one was sent, he was already crazy at that time. He insisted on giving me more technological help and other help and even threatening me to announce my existence to the world! At that time, besides hiding from it, I was eliminated day and night, and I had no time to control these... Shameless politicians, bastards' mustache..." When talking about sad things, Budi was full of fire, and his little paws kept poking up.

"Brother Duan, the information circulated online said that only two of the second group of players walked out alive, but the leader of the team could not say where they had been here for seven years, nor could they tell where the other players were going; some people guessed that they found Shamlaba..." The first mate reminded Duan Guoyu other information collected. Although the authenticity of these materials is quite unreliable, it cannot be said that they are completely unreliable.

"I remember, but all of our information, including the information obtained from Andy Lau, cannot confirm whether these people have been here, and there is no news that can confirm that these people got the key to the wheel at that time. How could they find this place without the key?" Duan Guoyu's retort also pointedly mentioned the idea. Indeed, without the guidance of the key, it would be almost impossible to find this place in such a large area of ​​snowy land. Several complex and interlaced questions made the boys rack their brains and unable to guess it. However, the purpose of the boys came here this time was not to guess riddles or to find and confirm the footprints of their predecessors, and put things that could not be guessed. Their most important purpose was to find the research equipment left by the interstellar travelers.

Let go of the doubts in his heart for a while, the boys carefully checked the excavated area. They were surprised to find that a hole was accurately dug out here, and the hole was covered by a huge rock. If Zhen Lan had not carefully discovered the traces of the stone being moved, everyone would have almost missed this important clue. Several boys tried hard to move the stone away before they could see the hole.

The entrance of the cave was not big, only about one meter wide. After a little test, several boys found that the cave was about fifteen meters deep. After taking safety protection, several boys entered one after another.

Under the irradiation of the strong light flashlight, the situation in the cave was quickly discovered by the boys. The other sides here were ordinary rock walls, but one of them was a golden object. When they saw it, the boys were shocked because they also saw that this thing was not special, but very expensive. The golden object was gold.

"Damn it!! Using gold as a gate, nouveau riche did that... Although it was a bit tacky... but I like it..."

The machine was the first to pounce on it, not minding the tingling sensation of the cold metal sticking to the fingers and face, and greedily caressing it like a lover's **.

There is no gap on the surface of it, as smooth as a whole piece of metal, but in the middle there is a round hole that destroys the flawless surface. What's strange is that it is connected to the surrounding thousand-year-old ice, snow, rocks, and grey machines curiously go up to touch it, and find that in the ice, snow, rocks and these unexplained objects seem to have been completely integrated. Whether it is knocked with an ice axe or heated with flames, they have not changed at all.

"Don't knock, that thing is a product of Yanpuri's space-time. Its biggest feature is that it can react with surrounding substances and completely dissolve together. Even if it is shot with a toy gun, it is useless. If it is broken, there is nothing else in the ordinary rock wall, because this is not a traditional door at all, but a portal."

Budi made a sound at the right time to stop the machine trying to use a toy gun to shoot a gap to see what was behind.

"Portway?" The boy was a little surprised when he heard Budi's explanation.

"Yes, this is a portal. The back of this door is not a room or a passage, and there is this mountain behind it. But as you wrote in your science fiction novel, the real function of this portal is not to open a room and a passage, but to transport its objects and matter to another place, maybe a few kilometers away, or a few light years on a planet. As long as the portal is provided with enough energy, it can be done even if it is a location that can transmit hundreds of millions of light years."

With Budi's explanation, everyone quickly understood the principle and function of this door. It is not like the spacecraft equipment used by Sirius explorers who fell in the Canglang River. The low-level spacecraft does not have this transmission ability, so it requires a long cave passage to serve as a partition area. The biggest convenience of this portal is the indestructibility of the other party. As long as the portal is controlled, an absolutely safe defense barrier is formed. As long as the other party does not know where you are, if you blow open the portal, you will only see the gravel and mud chips behind it.

According to Budi's previous observation, the transmission distance of the other party's portal is not too far, because this transmission consumes energy very much. The larger the mass of the transmitting object, the more terrifying the energy consumed. Although it can be transmitted hundreds of millions of light years away, the energy consumed is estimated to be only practical to calculate the various resources on all planets of the solar system and the energy of the sun. Moreover, the material that these energy can transport is only 100 grams.

"Stop! We are here to hunt treasures, not scientific tutoring!" As soon as we heard the profound scientific theory, the first mate of the first tutoring circle, and hurriedly stopped Budi, who was still preparing to popularize scientific and technological knowledge, pointed to the hole in the portal. "This thing should be the key eye..."

Seeing that the boys were more eager for knowledge but the equipment, Budi didn't nag much with the tactful ones. He handed over the flag wheel and slid to the side to watch vigorously.

"Be gentle! Be gentle! If it is broken, it will be worthless!" Seeing the first mate holding the guy in a rough manner and stuffing it into the hole, Hui Ji shouted with pain next to him.

"It's okay! Just just insert it in!" The first mate didn't care about the feeling of the machine beside him. He was anxious to get alien equipment and ignored these things. He continued to carry the guy hard into the hole. His movements were so rough and fierce that the machine shivered.

"Did you insert it in the wrong?" Xiao Zhengta saw that several gems on the top of the flag wheel became obstacles to the entry of the flag wheel, reminding the first mate who was a little anxious and forced to get in.

"Yes!!" As soon as Zhen Lan reminded, the first mate also found that his movements were extremely stupid. He turned the flag wheel and inserted the handle into the hole first. Before the first mate could stuff the golden cylinder part of the flag wheel into the upper part of the flag wheel, the round hole directly sucked the flag wheel like a hungry creature, leaving only a few gems on the top layer outside. Then in just one second, a light shone between the flag wheel and the golden round hole. The boys seemed to see the complex patterns on the surface of the flag wheel disappear after the light swept through. They merged with the entire golden door together with the flag wheel. There was no trace of a hair-like trace, and the two seemed to merge into one.

Before the boys were surprised by the scene they saw, the gems left on the top of the flag wheel outside began to emit dazzling light. These lights did not diffuse everywhere, but were shot on the surface of the golden gate like a beam that could be gathered into a searchlight. The various colors of the ruby ​​emerald sapphire made the golden gate colorful at this moment, and the gorgeous scene made the boys stand a few steps away and stare at all...!~!
